    Glaciers in the Arctic are not nearly as devoid of life as they might appear at first sight.

    In fact, carpets of ice and snow in Greenland and Iceland are practically crawling with microscopic life forms.

    Like seasonal zombies, many of these organisms lie dormant in winter, waking from their frozen slumber only with the summer melt.

    “A small puddle of meltwater on a glacier can easily have 4,000 different species living in it,” says microbiologist Alexandre Anesio from Aarhus University in Sweden.

    “They live on bacteria, algae, viruses, and microscopic fungi. It’s a whole ecosystem that we never knew existed until recently.”

    When researchers tested the ice and snow at two glaciers in the mid-to-late summer, one in Iceland and the other in Greenland, more than half the bacteria they found were active.

    The rest were dormant or dead.

    Within just a day of thawing, however, some of those dormant microbes regained the ability to read genes and produce amino acid building blocks – like the stiff cogs of a machine finally turning after six months of stillness.

    The findings suggest microbial communities on snow and ice can rapidly respond to changes in ice melt.

    But while adaptation in the face of climate change is usually considered a good thing, at least at a species level, it’s also true that a dramatic change in one organism can destabilize an entire ecosystem.

    In the future, rain and winter warming events in the Arctic are expected to increase with climate change, and some microbes are already thriving in the slush.

    The snow algae that performs best in Greenland’s meltwater is a deep dark purple, and in recent years, scientists like Anesio have noticed the color spreading.

    “When I travel to Greenland, I now see vast areas where the ice is completely dark because of the algae,” says Anesio.

    The dark appearance of the snow and ice ultimately means that more heat from the Sun is absorbed, increasing melt by 20 percent.

    Snow algae is not a factor included in current climate models. The missing microbes in ice are just one explanation for why Greenland’s glaciers could be melting faster in reality than predicted in models.

    A previous study [Nature Geoscience (below)], for instance, found that adding water to a snowpack over two months led to an increase in snow algae of 48 percent.

    After just three days of thawing in the lab, some samples from the current study contained 35 percent more active microbes than before.

    “Crucially, our results suggest that glacial microorganisms are able to respond to short melt-events occurring on the timescale of hours to days – which is sufficiently short that periodic melting on glacier surfaces potentially impacts the functioning of glacial ecosystems and biogeochemical cycles,” scientists write.

    “Enhanced winter warming is predicted to become more prevalent as a result of future climate change and could therefore bring about ecological changes to glaciers.”

    The future of Arctic snow and ice doesn’t just look darker. It is.

    The study was published in Geobiology.

    Study suggests ancient microorganisms helped cause massive volcanic events.

    Visually striking layers of burnt orange, yellow, silver, brown and blue-tinged black are characteristic of banded iron formations, sedimentary rocks that may have prompted some of the largest volcanic eruptions in Earth’s history, according to new research from Rice University.

    The rocks contain iron oxides that sank to the bottom of oceans long ago, forming dense layers that eventually turned to stone. The study published this week in Nature Geoscience [below] suggests the iron-rich layers could connect ancient changes at Earth’s surface — like the emergence of photosynthetic life — to planetary processes like volcanism and plate tectonics.

    In addition to linking planetary processes that were generally thought to be unconnected, the study could reframe scientists’ understanding of Earth’s early history and provide insight into processes that could produce habitable exoplanets far from our solar system.

    “These rocks tell — quite literally — the story of a changing planetary environment,” said Duncan Keller, the study’s lead author and a postdoctoral researcher in Rice’s Department of Earth, Environmental and Planetary Sciences. “They embody a change in the atmospheric and ocean chemistry.”

    Banded iron formations are chemical sediments precipitated directly from ancient seawater rich in dissolved iron. Metabolic actions of microorganisms, including photosynthesis, are thought to have facilitated the precipitation of the minerals, which formed layer upon layer over time along with chert (microcrystalline silicon dioxide). The largest deposits formed as oxygen accumulated in Earth’s atmosphere about 2.5 billion years ago.

    “These rocks formed in the ancient oceans, and we know that those oceans were later closed up laterally by plate tectonic processes,” Keller explained.

    The mantle, though solid, flows like a fluid at about the rate that fingernails grow. Tectonic plates — continent-sized sections of the crust and uppermost mantle — are constantly on the move, largely as a result of thermal convection currents in the mantle. Earth’s tectonic processes control the life cycles of oceans.

    “Just like the Pacific Ocean is being closed today — it’s subducting under Japan and under South America — ancient ocean basins were destroyed tectonically,” he said. “These rocks either had to get pushed up onto continents and be preserved — and we do see some preserved, that’s where the ones we’re looking at today come from — or subducted into the mantle.”

    Because of their high iron content, banded iron formations are denser than the mantle, which made Keller wonder whether subducted chunks of the formations sank all the way down and settled in the lowest region of the mantle near the top of Earth’s core. There, under immense temperature and pressure, they would have undergone profound changes as their minerals took on different structures.

    “There’s some very interesting work on the properties of iron oxides at those conditions,” Keller said. “They can become highly thermally and electrically conductive. Some of them transfer heat as easily as metals do. So it’s possible that, once in the lower mantle, these rocks would turn into extremely conductive lumps like hot plates.”

    Keller and his co-workers posit that regions enriched in subducted iron formations might aid the formation of mantle plumes, rising conduits of hot rock above thermal anomalies in the lower mantle that can produce enormous volcanoes like the ones that formed the Hawaiian Islands. “Underneath Hawaii, seismological data show us a hot conduit of upwelling mantle,” Keller said. “Imagine a hot spot on your stove burner. As the water in your pot is boiling, you’ll see more bubbles over a column of rising water in that area. Mantle plumes are sort of a giant version of that.”

    “We looked at the depositional ages of banded iron formations and the ages of large basaltic eruption events called large igneous provinces, and we found that there’s a correlation,” Keller said. “Many of the igneous events — which were so massive that the 10 or 15 largest may have been enough to resurface the entire planet — were preceded by banded iron formation deposition at intervals of roughly 241 million years, give or take 15 million. It’s a strong correlation with a mechanism that makes sense.”

    The study showed that there was a plausible length of time for banded iron formations to first be drawn deep into the lower mantle and to then influence heat flow to drive a plume toward Earth’s surface thousands of kilometers above.

    In his effort to trace the journey of banded iron formations, Keller crossed disciplinary boundaries and ran into unexpected insights.

    “If what’s happening in the early oceans, after microorganisms chemically change surface environments, ultimately creates an enormous outpouring of lava somewhere else on Earth 250 million years later, that means these processes are related and ‘talking’ to each other,” Keller said. “It also means it’s possible for related processes to have length scales that are far greater than people expected. To be able to infer this, we’ve had to draw on data from many different fields across mineralogy, geochemistry, geophysics and sedimentology.”

    Keller hopes the study will spur further research. “I hope this motivates people in the different fields that it touches,” he said. “I think it would be really cool if this got people talking to each other in renewed ways about how different parts of the Earth system are connected.

    Keller is part of the CLEVER Planets: Cycles of Life-Essential Volatile Elements in Rocky Planets program, an interdisciplinary, multi-institutional group of scientists led by Rajdeep Dasgupta, Rice’s W. Maurice Ewing Professor of Earth Systems Science in the Department of Earth, Environmental and Planetary Sciences.

    “This is an extremely interdisciplinary collaboration that’s looking at how volatile elements that are important for biology — carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur — behave in planets, at how planets acquire these elements and the role they play in potentially making planets habitable,” Keller said.

    “We’re using Earth as the best example that we have, but we’re trying to figure out what the presence or absence of one or some of these elements might mean for planets more generally,” he added.

    Cin-Ty Lee, Rice’s Harry Carothers Wiess Professor of Geology, Earth, Environmental and Planetary Sciences, and Dasgupta are co-authors on the study. Other co-authors are Santiago Tassara, an assistant professor at Bernardo O’Higgins University in Chile, and Leslie Robbins, an assistant professor at the University of Regina in Canada, who both did postdoctoral work at Yale University, and Yale Professor of Earth and Planetary Sciences Jay Ague, Keller’s doctoral adviser.

    NASA (80NSSC18K0828) and the Natural Sciences and Engineering Research Council of Canada (RGPIN-2021-02523) supported the research.

    Rice University [formally William Marsh Rice University] is a private research university in Houston, Texas. It is situated on a 300-acre campus near the Houston Museum District and is adjacent to the Texas Medical Center.
    Opened in 1912 after the murder of its namesake William Marsh Rice, Rice is a research university with an undergraduate focus. Its emphasis on education is demonstrated by a small student body and 6:1 student-faculty ratio. The university has a very high level of research activity. Rice is noted for its applied science programs in the fields of artificial heart research, structural chemical analysis, signal processing, space science, and nanotechnology. Rice has been a member of the Association of American Universities since 1985 and is classified among “R1: Doctoral Universities – Very high research activity”.
    The university is organized into eleven residential colleges and eight schools of academic study, including the Wiess School of Natural Sciences, the George R. Brown School of Engineering, the School of Social Sciences, School of Architecture, Shepherd School of Music and the School of Humanities. Rice’s undergraduate program offers more than fifty majors and two dozen minors, and allows a high level of flexibility in pursuing multiple degree programs. Additional graduate programs are offered through the Jesse H. Jones Graduate School of Business and the Susanne M. Glasscock School of Continuing Studies. Rice students are bound by the strict Honor Code, which is enforced by a student-run Honor Council.
    Rice competes in 14 NCAA Division I varsity sports and is a part of Conference USA, often competing with its cross-town rival the University of Houston. Intramural and club sports are offered in a wide variety of activities such as jiu jitsu, water polo, and crew.
    The university’s alumni include more than two dozen Marshall Scholars and a dozen Rhodes Scholars. Given the university’s close links to National Aeronautics Space Agency, it has produced a significant number of astronauts and space scientists. In business, Rice graduates include CEOs and founders of Fortune 500 companies; in politics, alumni include congressmen, cabinet secretaries, judges, and mayors. Two alumni have won the Nobel Prize.

    Background

    Rice University’s history began with the demise of Massachusetts businessman William Marsh Rice, who had made his fortune in real estate, railroad development and cotton trading in the state of Texas. In 1891, Rice decided to charter a free-tuition educational institute in Houston, bearing his name, to be created upon his death, earmarking most of his estate towards funding the project. Rice’s will specified the institution was to be “a competitive institution of the highest grade” and that only white students would be permitted to attend. On the morning of September 23, 1900, Rice, age 84, was found dead by his valet, Charles F. Jones, and was presumed to have died in his sleep. Shortly thereafter, a large check made out to Rice’s New York City lawyer, signed by the late Rice, aroused the suspicion of a bank teller, due to the misspelling of the recipient’s name. The lawyer, Albert T. Patrick, then announced that Rice had changed his will to leave the bulk of his fortune to Patrick, rather than to the creation of Rice’s educational institute. A subsequent investigation led by the District Attorney of New York resulted in the arrests of Patrick and of Rice’s butler and valet Charles F. Jones, who had been persuaded to administer chloroform to Rice while he slept. Rice’s friend and personal lawyer in Houston, Captain James A. Baker, aided in the discovery of what turned out to be a fake will with a forged signature. Jones was not prosecuted since he cooperated with the district attorney, and testified against Patrick. Patrick was found guilty of conspiring to steal Rice’s fortune and he was convicted of murder in 1901 (he was pardoned in 1912 due to conflicting medical testimony). Baker helped Rice’s estate direct the fortune, worth $4.6 million in 1904 ($131 million today), towards the founding of what was to be called the Rice Institute, later to become Rice University. The board took control of the assets on April 29 of that year.

    In 1907, the Board of Trustees selected the head of the Department of Mathematics and Astronomy at Princeton University, Edgar Odell Lovett, to head the Institute, which was still in the planning stages. He came recommended by Princeton University‘s president, Woodrow Wilson. In 1908, Lovett accepted the challenge, and was formally inaugurated as the Institute’s first president on October 12, 1912. Lovett undertook extensive research before formalizing plans for the new Institute, including visits to 78 institutions of higher learning across the world on a long tour between 1908 and 1909. Lovett was impressed by such things as the aesthetic beauty of the uniformity of the architecture at the University of Pennsylvania, a theme which was adopted by the Institute, as well as the residential college system at University of Cambridge (UK) in England, which was added to the Institute several decades later. Lovett called for the establishment of a university “of the highest grade,” “an institution of liberal and technical learning” devoted “quite as much to investigation as to instruction.” [We must] “keep the standards up and the numbers down,” declared Lovett. “The most distinguished teachers must take their part in undergraduate teaching, and their spirit should dominate it all.”
    Establishment and growth

    In 1911, the cornerstone was laid for the Institute’s first building, the Administration Building, now known as Lovett Hall in honor of the founding president. On September 23, 1912, the 12th anniversary of William Marsh Rice’s murder, the William Marsh Rice Institute for the Advancement of Letters, Science, and Art began course work with 59 enrolled students, who were known as the “59 immortals,” and about a dozen faculty. After 18 additional students joined later, Rice’s initial class numbered 77, 48 male and 29 female. Unusual for the time, Rice accepted coeducational admissions from its beginning, but on-campus housing would not become co-ed until 1957.

    Three weeks after opening, a spectacular international academic festival was held, bringing Rice to the attention of the entire academic world.

    Per William Marsh Rice’s will and Rice Institute’s initial charter, the students paid no tuition. Classes were difficult, however, and about half of Rice’s students had failed after the first 1912 term. At its first commencement ceremony, held on June 12, 1916, Rice awarded 35 bachelor’s degrees and one master’s degree. That year, the student body also voted to adopt the Honor System, which still exists today. Rice’s first doctorate was conferred in 1918 on mathematician Hubert Evelyn Bray.

    The Founder’s Memorial Statue, a bronze statue of a seated William Marsh Rice, holding the original plans for the campus, was dedicated in 1930, and installed in the central academic quad, facing Lovett Hall. The statue was crafted by John Angel. In 2020, Rice students petitioned the university to take down the statue due to the founder’s history as slave owner.

    During World War II, Rice Institute was one of 131 colleges and universities nationally that took part in the V-12 Navy College Training Program, which offered students a path to a Navy commission.

    The residential college system proposed by President Lovett was adopted in 1958, with the East Hall residence becoming Baker College, South Hall residence becoming Will Rice College, West Hall becoming Hanszen College, and the temporary Wiess Hall becoming Wiess College.

    In 1959, the Rice Institute Computer went online. 1960 saw Rice Institute formally renamed William Marsh Rice University. Rice acted as a temporary intermediary in the transfer of land between Humble Oil and Refining Company and NASA, for the creation of NASA’s Manned Spacecraft Center (now called Johnson Space Center) in 1962. President John F. Kennedy then made a speech at Rice Stadium reiterating that the United States intended to reach the moon before the end of the decade of the 1960s, and “to become the world’s leading space-faring nation”. The relationship of NASA with Rice University and the city of Houston has remained strong to the present day.

    The original charter of Rice Institute dictated that the university admit and educate, tuition-free, “the white inhabitants of Houston, and the state of Texas”. In 1963, the governing board of Rice University filed a lawsuit to allow the university to modify its charter to admit students of all races and to charge tuition. Ph.D. student Raymond Johnson became the first black Rice student when he was admitted that year. In 1964, Rice officially amended the university charter to desegregate its graduate and undergraduate divisions. The Trustees of Rice University prevailed in a lawsuit to void the racial language in the trust in 1966. Rice began charging tuition for the first time in 1965. In the same year, Rice launched a $33 million ($268 million) development campaign. $43 million ($283 million) was raised by its conclusion in 1970. In 1974, two new schools were founded at Rice, the Jesse H. Jones Graduate School of Management and the Shepherd School of Music. The Brown Foundation Challenge, a fund-raising program designed to encourage annual gifts, was launched in 1976 and ended in 1996 having raised $185 million. The Rice School of Social Sciences was founded in 1979.

    On-campus housing was exclusively for men for the first forty years, until 1957. Jones College was the first women’s residence on the Rice campus, followed by Brown College. According to legend, the women’s colleges were purposefully situated at the opposite end of campus from the existing men’s colleges as a way of preserving campus propriety, which was greatly valued by Edgar Odell Lovett, who did not even allow benches to be installed on campus, fearing that they “might lead to co-fraternization of the sexes”. The path linking the north colleges to the center of campus was given the tongue-in-cheek name of “Virgin’s Walk”. Individual colleges became coeducational between 1973 and 1987, with the single-sex floors of colleges that had them becoming co-ed by 2006. By then, several new residential colleges had been built on campus to handle the university’s growth, including Lovett College, Sid Richardson College, and Martel College.

    Late twentieth and early twenty-first century

    The Economic Summit of Industrialized Nations was held at Rice in 1990. Three years later, in 1993, the James A. Baker III Institute for Public Policy was created. In 1997, the Edythe Bates Old Grand Organ and Recital Hall and the Center for Nanoscale Science and Technology, renamed in 2005 for the late Nobel Prize winner and Rice professor Richard E. Smalley, were dedicated at Rice. In 1999, the Center for Biological and Environmental Nanotechnology was created. The Rice Owls baseball team was ranked #1 in the nation for the first time in that year (1999), holding the top spot for eight weeks.

    In 2003, the Owls won their first national championship in baseball, which was the first for the university in any team sport, beating Southwest Missouri State in the opening game and then the University of Texas and Stanford University twice each en route to the title. In 2008, President David Leebron issued a ten-point plan titled “Vision for the Second Century” outlining plans to increase research funding, strengthen existing programs, and increase collaboration. The plan has brought about another wave of campus constructions, including the erection the newly renamed BioScience Research Collaborative building (intended to foster collaboration with the adjacent Texas Medical Center), a new recreational center and the renovated Autry Court basketball stadium, and the addition of two new residential colleges, Duncan College and McMurtry College.

    Beginning in late 2008, the university considered a merger with Baylor College of Medicine, though the merger was ultimately rejected in 2010. Rice undergraduates are currently guaranteed admission to Baylor College of Medicine upon graduation as part of the Rice/Baylor Medical Scholars program. According to History Professor John Boles’ recent book University Builder: Edgar Odell Lovett and the Founding of the Rice Institute, the first president’s original vision for the university included hopes for future medical and law schools.

    In 2018, the university added an online MBA program, MBA@Rice.

    In June 2019, the university’s president announced plans for a task force on Rice’s “past in relation to slave history and racial injustice”, stating that “Rice has some historical connections to that terrible part of American history and the segregation and racial disparities that resulted directly from it”.

    Campus

    Rice’s campus is a heavily wooded 285-acre (115-hectare) tract of land in the museum district of Houston, located close to the city of West University Place.

    Five streets demarcate the campus: Greenbriar Street, Rice Boulevard, Sunset Boulevard, Main Street, and University Boulevard. For most of its history, all of Rice’s buildings have been contained within this “outer loop”. In recent years, new facilities have been built close to campus, but the bulk of administrative, academic, and residential buildings are still located within the original pentagonal plot of land. The new Collaborative Research Center, all graduate student housing, the Greenbriar building, and the Wiess President’s House are located off-campus.

    Rice prides itself on the amount of green space available on campus; there are only about 50 buildings spread between the main entrance at its easternmost corner, and the parking lots and Rice Stadium at the West end. The Lynn R. Lowrey Arboretum, consisting of more than 4000 trees and shrubs (giving birth to the legend that Rice has a tree for every student), is spread throughout the campus.
    The university’s first president, Edgar Odell Lovett, intended for the campus to have a uniform architecture style to improve its aesthetic appeal. To that end, nearly every building on campus is noticeably Byzantine in style, with sand and pink-colored bricks, large archways and columns being a common theme among many campus buildings. Noteworthy exceptions include the glass-walled Brochstein Pavilion, Lovett College with its Brutalist-style concrete gratings, Moody Center for the Arts with its contemporary design, and the eclectic-Mediterranean Duncan Hall. In September 2011, Travel+Leisure listed Rice’s campus as one of the most beautiful in the United States.

    The university and Houston Independent School District jointly established The Rice School-a kindergarten through 8th grade public magnet school in Houston. The school opened in August 1994. Through Cy-Fair ISD Rice University offers a credit course based summer school for grades 8 through 12. They also have skills based classes during the summer in the Rice Summer School.

    Innovation District

    In early 2019 Rice announced the site where the abandoned Sears building in Midtown Houston stood along with its surrounding area would be transformed into the “The Ion” the hub of the 16-acre South Main Innovation District. President of Rice David Leebron stated “We chose the name Ion because it’s from the Greek ienai, which means ‘go’. We see it as embodying the ever-forward motion of discovery, the spark at the center of a truly original idea.”

    Students of Rice and other Houston-area colleges and universities making up the Student Coalition for a Just and Equitable Innovation Corridor are advocating for a Community Benefits Agreement (CBA)-a contractual agreement between a developer and a community coalition. Residents of neighboring Third Ward and other members of the Houston Coalition for Equitable Development Without Displacement (HCEDD) have faced consistent opposition from the City of Houston and Rice Management Company to a CBA as traditionally defined in favor of an agreement between the latter two entities without a community coalition signatory.

    Organization

    Rice University is chartered as a non-profit organization and is governed by a privately appointed board of trustees. The board consists of a maximum of 25 voting members who serve four-year terms. The trustees serve without compensation and a simple majority of trustees must reside in Texas including at least four within the greater Houston area. The board of trustees delegates its power by appointing a president to serve as the chief executive of the university. David W. Leebron was appointed president in 2004 and succeeded Malcolm Gillis who served since 1993. The provost six vice presidents and other university officials report to the president. The president is advised by a University Council composed of the provost, eight members of the Faculty Council, two staff members, one graduate student, and two undergraduate students. The president presides over a Faculty Council which has the authority to alter curricular requirements, establish new degree programs, and approve candidates for degrees.

    The university’s academics are organized into several schools. Schools that have undergraduate and graduate programs include:

    The Rice University School of Architecture
    The George R. Brown School of Engineering
    The School of Humanities
    The Shepherd School of Music
    The Wiess School of Natural Sciences
    The Rice University School of Social Sciences

    Two schools have only graduate programs:

    The Jesse H. Jones Graduate School of Management
    The Susanne M. Glasscock School of Continuing Studies

    Rice’s undergraduate students benefit from a centralized admissions process which admits new students to the university as a whole, rather than a specific school (the schools of Music and Architecture are decentralized). Students are encouraged to select the major path that best suits their desires; a student can later decide that they would rather pursue study in another field or continue their current coursework and add a second or third major. These transitions are designed to be simple at Rice with students not required to decide on a specific major until their sophomore year of study.

    Rice’s academics are organized into six schools which offer courses of study at the graduate and undergraduate level, with two more being primarily focused on graduate education, while offering select opportunities for undergraduate students. Rice offers 360 degrees in over 60 departments. There are 40 undergraduate degree programs, 51 masters programs, and 29 doctoral programs.

    Faculty members of each of the departments elect chairs to represent the department to each School’s dean and the deans report to the Provost who serves as the chief officer for academic affairs.

    Rice Management Company

    The Rice Management Company manages the $6.5 billion Rice University endowment (June 2019) and $957 million debt. The endowment provides 40% of Rice’s operating revenues. Allison Thacker is the President and Chief Investment Officer of the Rice Management Company, having joined the university in 2011.

    Academics

    Rice is a medium-sized highly residential research university. The majority of enrollments are in the full-time four-year undergraduate program emphasizing arts & sciences and professions. There is a high graduate coexistence with the comprehensive graduate program and a very high level of research activity. It is accredited by the Southern Association of Colleges and Schools Commission on Colleges as well as the professional accreditation agencies for engineering, management, and architecture.

    Each of Rice’s departments is organized into one of three distribution groups, and students whose major lies within the scope of one group must take at least 3 courses of at least 3 credit hours each of approved distribution classes in each of the other two groups, as well as completing one physical education course as part of the LPAP (Lifetime Physical Activity Program) requirement. All new students must take a Freshman Writing Intensive Seminar (FWIS) class, and for students who do not pass the university’s writing composition examination (administered during the summer before matriculation), FWIS 100, a writing class, becomes an additional requirement.

    The majority of Rice’s undergraduate degree programs grant B.S. or B.A. degrees. Rice has recently begun to offer minors in areas such as business, energy and water sustainability, and global health.

    Student body

    As of fall 2014, men make up 52% of the undergraduate body and 64% of the professional and post-graduate student body. The student body consists of students from all 50 states, including the District of Columbia, two U.S. Territories, and 83 foreign countries. Forty percent of degree-seeking students are from Texas.

    Residential colleges

    In 1957, Rice University implemented a residential college system, which was proposed by the university’s first president, Edgar Odell Lovett. The system was inspired by existing systems in place at University of Oxford (UK) and University of Cambridge (UK) and at several other universities in the United States, most notably Yale University. The existing residences known as East, South, West, and Wiess Halls became Baker, Will Rice, Hanszen, and Wiess Colleges, respectively.

    Student-run media

    Rice has a weekly student newspaper (The Rice Thresher), a yearbook (The Campanile), college radio station (KTRU Rice Radio), and now defunct, campus-wide student television station (RTV5). They are based out of the RMC student center. In addition, Rice hosts several student magazines dedicated to a range of different topics; in fact, the spring semester of 2008 saw the birth of two such magazines, a literary sex journal called Open and an undergraduate science research magazine entitled Catalyst.

    The Rice Thresher is published every Wednesday and is ranked by Princeton Review as one of the top campus newspapers nationally for student readership. It is distributed around campus, and at a few other local businesses and has a website. The Thresher has a small, dedicated staff and is known for its coverage of campus news, open submission opinion page, and the satirical Backpage, which has often been the center of controversy. The newspaper has won several awards from the College Media Association, Associated Collegiate Press and Texas Intercollegiate Press Association.

    The Rice Campanile was first published in 1916 celebrating Rice’s first graduating class. It has published continuously since then, publishing two volumes in 1944 since the university had two graduating classes due to World War II. The website was created sometime in the early to mid 2000’s. The 2015 won the first place Pinnacle for best yearbook from College Media Association.

    KTRU Rice Radio is the student-run radio station. Though most DJs are Rice students, anyone is allowed to apply. It is known for playing genres and artists of music and sound unavailable on other radio stations in Houston, and often, the US. The station takes requests over the phone or online. In 2000 and 2006, KTRU won Houston Press’ Best Radio Station in Houston. In 2003, Rice alum and active KTRU DJ DL’s hip-hip show won Houston PressBest Hip-hop Radio Show. On August 17, 2010, it was announced that Rice University had been in negotiations to sell the station’s broadcast tower, FM frequency and license to the University of Houston System to become a full-time classical music and fine arts programming station. The new station, KUHA, would be operated as a not-for-profit outlet with listener supporters. The FCC approved the sale and granted the transfer of license to the University of Houston System on April 15, 2011, however, KUHA proved to be an even larger failure and so after four and a half years of operation, The University of Houston System announced that KUHA’s broadcast tower, FM frequency and license were once again up for sale in August 2015. KTRU continued to operate much as it did previously, streaming live on the Internet, via apps, and on HD2 radio using the 90.1 signal. Under student leadership, KTRU explored the possibility of returning to FM radio for a number of years. In spring 2015, KTRU was granted permission by the FCC to begin development of a new broadcast signal via LPFM radio. On October 1, 2015, KTRU made its official return to FM radio on the 96.1 signal. While broadcasting on HD2 radio has been discontinued, KTRU continues to broadcast via internet in addition to its LPFM signal.

    RTV5 is a student-run television network available as channel 5 on campus. RTV5 was created initially as Rice Broadcast Television in 1997; RBT began to broadcast the following year in 1998, and aired its first live show across campus in 1999. It experienced much growth and exposure over the years with successful programs like Drinking with Phil, The Meg & Maggie Show, which was a variety and call-in show, a weekly news show, and extensive live coverage in December 2000 of the shut down of KTRU by the administration. In spring 2001, the Rice undergraduate community voted in the general elections to support RBT as a blanket tax organization, effectively providing a yearly income of $10,000 to purchase new equipment and provide the campus with a variety of new programming. In the spring of 2005, RBT members decided the station needed a new image and a new name: Rice Television 5. One of RTV5’s most popular shows was the 24-hour show, where a camera and couch placed in the RMC stayed on air for 24 hours. One such show is held in fall and another in spring, usually during a weekend allocated for visits by prospective students. RTV5 has a video on demand site at rtv5.rice.edu. The station went off the air in 2014 and changed its name to Rice Video Productions. In 2015 the group’s funding was threatened, but ultimately maintained. In 2016 the small student staff requested to no longer be a blanket-tax organization. In the fall of 2017, the club did not register as a club.

    The Rice Review, also known as R2, is a yearly student-run literary journal at Rice University that publishes prose, poetry, and creative nonfiction written by undergraduate students, as well as interviews. The journal was founded in 2004 by creative writing professor and author Justin Cronin.

    The Rice Standard was an independent, student-run variety magazine modeled after such publications as The New Yorker and Harper’s. Prior to fall 2009, it was regularly published three times a semester with a wide array of content, running from analyses of current events and philosophical pieces to personal essays, short fiction and poetry. In August 2009, The Standard transitioned to a completely online format with the launch of their redesigned website, http://www.ricestandard.org. The first website of its kind on Rice’s campus, The Standard featured blog-style content written by and for Rice students. The Rice Standard had around 20 regular contributors, and the site features new content every day (including holidays). In 2017 no one registered The Rice Standard as a club within the university.

    Open, a magazine dedicated to “literary sex content,” predictably caused a stir on campus with its initial publication in spring 2008. A mixture of essays, editorials, stories and artistic photography brought Open attention both on campus and in the Houston Chronicle. The third and last annual edition of Open was released in spring of 2010.

    Athletics

    Rice plays in NCAA Division I athletics and is part of Conference USA. Rice was a member of the Western Athletic Conference before joining Conference USA in 2005. Rice is the second-smallest school, measured by undergraduate enrollment, competing in NCAA Division I FBS football, only ahead of Tulsa.

    The Rice baseball team won the 2003 College World Series, defeating Stanford, giving Rice its only national championship in a team sport. The victory made Rice University the smallest school in 51 years to win a national championship at the highest collegiate level of the sport. The Rice baseball team has played on campus at Reckling Park since the 2000 season. As of 2010, the baseball team has won 14 consecutive conference championships in three different conferences: the final championship of the defunct Southwest Conference, all nine championships while a member of the Western Athletic Conference, and five more championships in its first five years as a member of Conference USA. Additionally, Rice’s baseball team has finished third in both the 2006 and 2007 College World Series tournaments. Rice now has made six trips to Omaha for the CWS. In 2004, Rice became the first school ever to have three players selected in the first eight picks of the MLB draft when Philip Humber, Jeff Niemann, and Wade Townsend were selected third, fourth, and eighth, respectively. In 2007, Joe Savery was selected as the 19th overall pick.

    Rice has been very successful in women’s sports in recent years. In 2004–05, Rice sent its women’s volleyball, soccer, and basketball teams to their respective NCAA tournaments. The women’s swim team has consistently brought at least one member of their team to the NCAA championships since 2013. In 2005–06, the women’s soccer, basketball, and tennis teams advanced, with five individuals competing in track and field. In 2006–07, the Rice women’s basketball team made the NCAA tournament, while again five Rice track and field athletes received individual NCAA berths. In 2008, the women’s volleyball team again made the NCAA tournament. In 2011 the Women’s Swim team won their first conference championship in the history of the university. This was an impressive feat considering they won without having a diving team. The team repeated their C-USA success in 2013 and 2014. In 2017, the women’s basketball team, led by second-year head coach Tina Langley, won the Women’s Basketball Invitational, defeating UNC-Greensboro 74–62 in the championship game at Tudor Fieldhouse. Though not a varsity sport, Rice’s ultimate frisbee women’s team, named Torque, won consecutive Division III national championships in 2014 and 2015.

    In 2006, the football team qualified for its first bowl game since 1961, ending the second-longest bowl drought in the country at the time. On December 22, 2006, Rice played in the New Orleans Bowl in New Orleans, Louisiana against the Sun Belt Conference champion, Troy. The Owls lost 41–17. The bowl appearance came after Rice had a 14-game losing streak from 2004–05 and went 1–10 in 2005. The streak followed an internally authorized 2003 McKinsey report that stated football alone was responsible for a $4 million deficit in 2002. Tensions remained high between the athletic department and faculty, as a few professors who chose to voice their opinion were in favor of abandoning the football program. The program success in 2006, the Rice Renaissance, proved to be a revival of the Owl football program, quelling those tensions. David Bailiff took over the program in 2007 and has remained head coach. Jarett Dillard set an NCAA record in 2006 by catching a touchdown pass in 13 consecutive games and took a 15-game overall streak into the 2007 season.

    In 2008, the football team posted a 9-3 regular season, capping off the year with a 38–14 victory over Western Michigan University in the Texas Bowl. The win over Western Michigan marked the Owls’ first bowl win in 45 years.

    Rice Stadium also serves as the performance venue for the university’s Marching Owl Band, or “MOB.” Despite its name, the MOB is a scatter band that focuses on performing humorous skits and routines rather than traditional formation marching.

    Rice Owls men’s basketball won 10 conference titles in the former Southwest Conference (1918, 1935*, 1940, 1942*, 1943*, 1944*, 1945, 1949*, 1954*, 1970; * denotes shared title). Most recently, guard Morris Almond was drafted in the first round of the 2007 NBA Draft by the Utah Jazz. Rice named former Cal Bears head coach Ben Braun as head basketball coach to succeed Willis Wilson, fired after Rice finished the 2007–2008 season with a winless (0-16) conference record and overall record of 3-27.

    Microbes are by far the most important factor in determining how much carbon is stored in the soil, according to a new study with implications for mitigating climate change and improving soil health for agriculture and food production.

    The research is the first to measure the relative importance of microbial processes in the soil carbon cycle. The study’s authors found that the role microbes play in storing carbon in the soil is at least four times more important than any other process, including decomposition of biomatter.

    That’s important information: Earth’s soils hold three times more carbon than the atmosphere, creating a vital carbon sink in the fight against climate change.

    The study, published May 24 in Nature [below], describes a novel approach to better understanding soil carbon dynamics by combining a microbial computer model with data assimilation and machine learning, to analyze big data related to the carbon cycle.

    The method measured microbial carbon use efficiency which tells how much carbon was used by microbes for growth versus how much was used for metabolism. When used for growth, carbon becomes sequestered by microbes in cells and ultimately in the soil, and when used for metabolism, carbon is released as a side product in the air as carbon dioxide, where it acts as a greenhouse gas. Ultimately, growth of microbes is more important than metabolism in determining how much carbon is stored in the soil.

    “This work reveals that microbial carbon use efficiency is more important than any other factor in determining soil carbon storage,” said Yiqi Luo, the Liberty Hyde Bailey Professor in the School of Integrative Plant Science in the College of Agriculture and Life Sciences, and the paper’s senior author.

    The new insights point agricultural researchers toward studying farm management practices that may influence microbial carbon use efficiency to improve soil health, which also helps ensure greater food security. Future studies may investigate steps to increase overall soil carbon sequestration by microbes. Researchers may also study how different types of microbes and substrates (such as those high in sugars) may influence soil carbon storage.

    Soil carbon dynamics have been studied for the last two centuries, but those studies were mainly concerned with how much carbon gets into the soil from leaf litter and roots, and how much is lost to the air in the form of CO2 when organic matter decomposes.

    “But we are the first group that can evaluate the relative importance of microbial processes versus other processes,” Luo said.

    In an example of cutting-edge digital agriculture, Luo and colleagues made a breakthrough and developed a method to integrate big data into an earth system computer model by using data assimilation and machine learning.

    The model revealed that overall carbon use efficiency of microbe colonies was at least four times as important as any of the other components that were evaluated, including decomposition and carbon inputs.

    The new process-based model, machine learning approach, which made this result possible for the first time, opens the possibility for applying the method to analyze other types of big data sets.

    Feng Tao, a researcher at Tsinghua University, Beijing, is the paper’s first author. Xiaomeng Huang, a professor at Tsinghua University, is a corresponding author, along with Luo. Benjamin Houlton, the Ronald P. Lynch Dean of CALS and professor in the departments of Ecology and Evolutionary Biology and of Global Development; and Johannes Lehmann, the Liberty Hyde Bailey Professor in the Soil and Crop Sciences Section of the School of Integrative Plant Science in CALS, are both co-authors.

    The study was funded by the National Science Foundation, the National Key Research and Development Program of China and the National Natural Science Foundation of China, among others.

    The New York State SUNY-College of Agriculture and Life Sciences at Cornell University is a statutory college and one of the four New York State contract colleges on the Cornell University campus in Ithaca, New York. With enrollment of approximately 3,100 undergraduate and 1,000 graduate students, CALS is the third-largest college of its kind in the United States and the second-largest undergraduate college on the Cornell campus.

    Established as a Land-grant college, CALS administrates New York’s cooperative extension program jointly with the College of Human Ecology. CALS runs the New York State Agricultural Experiment Station in Geneva, New York, and the Cornell University Agricultural Experiment Station, as well as other research facilities in New York.

    In 2007-08, CALS total budget (excluding the Geneva Station) is $283 million, with $96 million coming from tuition and $52 million coming from state appropriations. The Geneva Station budget was an additional $25 million.

    Academic programs

    CALS offers more than 20 majors, each with a focus on Life Sciences, Applied Social Sciences, Environmental Sciences and Agriculture and Food. CALS undergraduate programs lead to a Bachelor of Science degree in one of 23 different majors. The Applied Economics and Management program, for example, was ranked 3rd nationally in BusinessWeek’s Best Undergraduate Business Programs, 2012, edition. CALS also offers graduate degrees in various fields of study, including the M.A.T., M.L.A., M.P.S., M.S., and Ph.D.

    Cornell’s College of Agriculture and Life Sciences is the most renowned institution in its field. In 2019, it is ranked 1st in the “Food and Nutrition” and “Agricultural Sciences” sectors of Niche.com

    With an admission rate of 11.5% for the fall of 2018, admission into the college is extremely competitive and in the middle relative to the other colleges at Cornell.

    Once called “the first American university” by educational historian Frederick Rudolph, Cornell University represents a distinctive mix of eminent scholarship and democratic ideals. Adding practical subjects to the classics and admitting qualified students regardless of nationality, race, social circumstance, gender, or religion was quite a departure when Cornell was founded in 1865.

    Today’s Cornell reflects this heritage of egalitarian excellence. It is home to the nation’s first colleges devoted to hotel administration, industrial and labor relations, and veterinary medicine. Both a private university and the land-grant institution of New York State, Cornell University is the most educationally diverse member of the Ivy League.

    On the Ithaca campus alone nearly 20,000 students representing every state and 120 countries choose from among 4,000 courses in 11 undergraduate, graduate, and professional schools. Many undergraduates participate in a wide range of interdisciplinary programs, play meaningful roles in original research, and study in Cornell programs in Washington, New York City, and the world over.

    Cornell University is a private, statutory, Ivy League and land-grant research university in Ithaca, New York. Founded in 1865 by Ezra Cornell and Andrew Dickson White, the university was intended to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell’s founding principle, a popular 1868 quotation from founder Ezra Cornell: “I would found an institution where any person can find instruction in any study.”

    The university is broadly organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers two satellite medical campuses, one in New York City and one in Education City, Qatar, and The Jacobs Technion-Cornell Institute in New York City, a graduate program that incorporates technology, business, and creative thinking. The program moved from Google’s Chelsea Building in New York City to its permanent campus on Roosevelt Island in September 2017.

    Cornell is one of the few private land grant universities in the United States. Of its seven undergraduate colleges, three are state-supported statutory or contract colleges through The State University of New York (SUNY) system, including its Agricultural and Human Ecology colleges as well as its Industrial Labor Relations school. Of Cornell’s graduate schools, only the veterinary college is state-supported. As a land grant college, Cornell operates a cooperative extension outreach program in every county of New York and receives annual funding from the State of New York for certain educational missions. The Cornell University Ithaca Campus comprises 745 acres, but is much larger when the Cornell Botanic Gardens (more than 4,300 acres) and the numerous university-owned lands in New York City are considered.

    Alumni and affiliates of Cornell have reached many notable and influential positions in politics, media, and science. As of January 2021, 61 Nobel laureates, four Turing Award winners and one Fields Medalist have been affiliated with Cornell. Cornell counts more than 250,000 living alumni, and its former and present faculty and alumni include 34 Marshall Scholars, 33 Rhodes Scholars, 29 Truman Scholars, 7 Gates Scholars, 55 Olympic Medalists, 10 current Fortune 500 CEOs, and 35 billionaire alumni. Since its founding, Cornell has been a co-educational, non-sectarian institution where admission has not been restricted by religion or race. The student body consists of more than 15,000 undergraduate and 9,000 graduate students from all 50 American states and 119 countries.

    History

    Cornell University was founded on April 27, 1865; the New York State (NYS) Senate authorized the university as the state’s land grant institution. Senator Ezra Cornell offered his farm in Ithaca, New York, as a site and $500,000 of his personal fortune as an initial endowment. Fellow senator and educator Andrew Dickson White agreed to be the first president. During the next three years, White oversaw the construction of the first two buildings and traveled to attract students and faculty. The university was inaugurated on October 7, 1868, and 412 men were enrolled the next day.

    Cornell developed as a technologically innovative institution, applying its research to its own campus and to outreach efforts. For example, in 1883 it was one of the first university campuses to use electricity from a water-powered dynamo to light the grounds. Since 1894, Cornell has included colleges that are state funded and fulfill statutory requirements; it has also administered research and extension activities that have been jointly funded by state and federal matching programs.

    Cornell has had active alumni since its earliest classes. It was one of the first universities to include alumni-elected representatives on its Board of Trustees. Cornell was also among the Ivies that had heightened student activism during the 1960s related to cultural issues; civil rights; and opposition to the Vietnam War, with protests and occupations resulting in the resignation of Cornell’s president and the restructuring of university governance. Today the university has more than 4,000 courses. Cornell is also known for the Residential Club Fire of 1967, a fire in the Residential Club building that killed eight students and one professor.

    Since 2000, Cornell has been expanding its international programs. In 2004, the university opened the Weill Cornell Medical College in Qatar. It has partnerships with institutions in India, Singapore, and the People’s Republic of China. Former president Jeffrey S. Lehman described the university, with its high international profile, a “transnational university”. On March 9, 2004, Cornell and Stanford University laid the cornerstone for a new ‘Bridging the Rift Center’ to be built and jointly operated for education on the Israel–Jordan border.

    Research

    Cornell, a research university, is ranked fourth in the world in producing the largest number of graduates who go on to pursue PhDs in engineering or the natural sciences at American institutions, and fifth in the world in producing graduates who pursue PhDs at American institutions in any field. Research is a central element of the university’s mission; in 2009 Cornell spent $671 million on science and engineering research and development, the 16th highest in the United States.

    Cornell is a member of the Association of American Universities and is classified among “R1: Doctoral Universities – Very high research activity”.

    For the 2016–17 fiscal year, the university spent $984.5 million on research. Federal sources constitute the largest source of research funding, with total federal investment of $438.2 million. The agencies contributing the largest share of that investment are The Department of Health and Human Services and the National Science Foundation , accounting for 49.6% and 24.4% of all federal investment, respectively. Cornell was on the top-ten list of U.S. universities receiving the most patents in 2003, and was one of the nation’s top five institutions in forming start-up companies. In 2004–05, Cornell received 200 invention disclosures; filed 203 U.S. patent applications; completed 77 commercial license agreements; and distributed royalties of more than $4.1 million to Cornell units and inventors.

    Since 1962, Cornell has been involved in unmanned missions to Mars. In the 21st century, Cornell had a hand in the Mars Exploration Rover Mission. Cornell’s Steve Squyres, Principal Investigator for the Athena Science Payload, led the selection of the landing zones and requested data collection features for the Spirit and Opportunity rovers. NASA-JPL/Caltech engineers took those requests and designed the rovers to meet them. The rovers, both of which have operated long past their original life expectancies, are responsible for the discoveries that were awarded 2004 Breakthrough of the Year honors by Science. Control of the Mars rovers has shifted between National Aeronautics and Space Administration’s Jet Propulsion Laboratory at Caltech and Cornell’s Space Sciences Building.

    Further, Cornell researchers discovered the rings around the planet Uranus, and Cornell built and operated the telescope at Arecibo Observatory located in Arecibo, Puerto Rico(US) until 2011, when they transferred the operations to SRI International, the Universities Space Research Association and the Metropolitan University of Puerto Rico [Universidad Metropolitana de Puerto Rico].

    The Automotive Crash Injury Research Project was begun in 1952. It pioneered the use of crash testing, originally using corpses rather than dummies. The project discovered that improved door locks; energy-absorbing steering wheels; padded dashboards; and seat belts could prevent an extraordinary percentage of injuries.

    In the early 1980s, Cornell deployed the first IBM 3090-400VF and coupled two IBM 3090-600E systems to investigate coarse-grained parallel computing. In 1984, the National Science Foundation began work on establishing five new supercomputer centers, including the Cornell Center for Advanced Computing, to provide high-speed computing resources for research within the United States. As a National Science Foundation center, Cornell deployed the first IBM Scalable Parallel supercomputer.

    In the 1990s, Cornell developed scheduling software and deployed the first supercomputer built by Dell. Most recently, Cornell deployed Red Cloud, one of the first cloud computing services designed specifically for research. Today, the center is a partner on the National Science Foundation XSEDE-Extreme Science Engineering Discovery Environment supercomputing program, providing coordination for XSEDE architecture and design, systems reliability testing, and online training using the Cornell Virtual Workshop learning platform.

    Cornell scientists have researched the fundamental particles of nature for more than 70 years. Cornell physicists, such as Hans Bethe, contributed not only to the foundations of nuclear physics but also participated in the Manhattan Project. In the 1930s, Cornell built the second cyclotron in the United States. In the 1950s, Cornell physicists became the first to study synchrotron radiation.

    During the 1990s, the Cornell Electron Storage Ring, located beneath Alumni Field, was the world’s highest-luminosity electron-positron collider. After building the synchrotron at Cornell, Robert R. Wilson took a leave of absence to become the founding director of DOE’s Fermi National Accelerator Laboratory, which involved designing and building the largest accelerator in the United States.

    Cornell’s accelerator and high-energy physics groups are involved in the design of the proposed ILC-International Linear Collider (JP) and plan to participate in its construction and operation. The International Linear Collider (JP), to be completed in the late 2010s, will complement the The European Organization for Nuclear Research [La Organización Europea para la Investigación Nuclear][Organisation européenne pour la recherche nucléaire] [Europäische Organisation für Kernforschung](CH)[CERN] Large Hadron Collider(CH) and shed light on questions such as the identity of dark matter and the existence of extra dimensions.

    As part of its research work, Cornell has established several research collaborations with universities around the globe. For example, a partnership with the University of Sussex(UK) (including the Institute of Development Studies at Sussex) allows research and teaching collaboration between the two institutions.

    Crispr Microbiome

    $70M funding will catalyze a bold new initiative led by Jennifer Doudna and Jill Banfield to apply precision genome editing to microbial communities.

    The Audacious Project, an initiative housed at TED, encourages the world’s greatest change-makers to dream bigger. A new initiative led by Jennifer Doudna and Jill Banfield at the Innovative Genomics Institute and announced today at the TED Conference in Vancouver is a big dream that uses the smallest tools: microbes.

    The research initiative, “Engineering the Microbiome with CRISPR to Improve our Climate and Health,” will receive $70 million in funding from donors, making it the largest scientific project funded through The Audacious Project to date. It involves a close collaboration across three University of California (UC) campuses — the Innovative Genomics Institute (IGI) at UC-Berkeley, UC-Davis, and UC-San Francisco — that capitalizes on the strengths of each institution.

    “This cutting-edge initiative will harness the University of California’s research prowess to solve real-world problems in areas that affect us all: sustainability and health,” says University of California President Michael V. Drake, MD. “I’m very pleased to see multiple UC entities working collaboratively to develop and deploy new technology for the public good. I’m grateful to our philanthropic partners for supporting impactful research that will change the world for the better.”

    The two project leaders have a unique connection: Doudna is best known for her groundbreaking work developing CRISPR genome editing, for which she received the Nobel Prize in Chemistry in 2020; Banfield studied microbial communities for decades and first introduced Doudna to CRISPR systems in bacteria, at a fortuitous meeting at a UC Berkeley café in 2006. Now, they’re bringing their specialties together to develop a new toolkit to address global problems in climate and human health by applying CRISPR genome editing to complex microbial communities known as “microbiomes.”

    “This is an exciting new frontier for CRISPR,” says Doudna. “The precision tools we’re developing will help us understand how microbiomes work at the fundamental level. And we can leverage that knowledge to address problems caused by microbes.”

    The Supersized Impact of Miniature Microbes

    Though invisible to the naked eye, microbes — bacteria, fungi, viruses, and other microscopic organisms — are everywhere. They account for the vast majority of life’s diversity and they shape the world in significant but often overlooked ways. While scientists have historically studied microbes individually, they commonly live in complex communities, or microbiomes, in the environment around us, and on and even in our bodies. In fact, there are more microbial cells in our body than human cells, and we depend on them for a variety of functions — but when out of balance, microbiomes can also create problems instead.

    There is a growing understanding in the medical community that microbiomes in our gut, our airways, and on our skin can significantly impact health issues, including asthma, allergies, obesity, cardiovascular disease, and neurological disorders like Alzheimer’s disease. These health issues affect hundreds of millions of people around the world, and in many cases disproportionately affect people of color and low-income communities.

    Microbiomes also represent a significant and largely unaddressed source of global greenhouse gas emissions. Microbes from livestock, agricultural soils, and landfills emit methane and nitrous oxide. Cow burps are commonly pointed to as a major source of methane, but those burps actually originate from methane-producing microbes in the animals’ guts.

    Currently, the tools we have to address problem-causing microbiomes are blunt. Antibiotics wipe out whole populations of beneficial and harmful bacteria, probiotics have limited impact, and fecal transplants have shown some promise in specific areas, but face concerns with safety and acceptance.

    The IGI team is developing a revolutionary new approach to precisely control microbiomes by building on two state-of-the-art methods pioneered by Doudna and Banfield that have both developed significantly over the past decade: CRISPR genome editing and genome-resolved metagenomics. Less than 1 percent of microbial species can be cultured in the lab, but genome-resolved metagenomics removes the need to grow individual species one-by-one by providing a detailed map of all organisms in a microbiome and the functions of their genes. Banfield and collaborators used these techniques in a 2016 paper in Nature Microbiology to develop a new, clearer picture of the tree of life, showing just how much of the tree is dominated by unseen microbes.

    Pairing genome-resolved metagenomics with CRISPR genome editing provides the opportunity and the necessary knowledge to fine-tune microbiomes by making highly targeted changes to specific genes in specific microbes.

    “DNA is the instruction manual for an organism and CRISPR is a tool that can rewrite the manuals to fundamentally change how organisms work,” says Banfield. “Genome-resolved metagenomics is the way we can read the instruction manual for any organism and it has brought to light tens of thousands of organisms that we didn’t even know existed.”

    In a 2022 paper in “Nature Microbiology” [below], Doudna, Banfield, and their teams showed for the first time that they could precisely edit genes directly within complex microbiomes, including model systems that replicated natural soil and infant gut microbiomes. The new initiative builds on that work, and is focused on refining the toolkit into a precision microbiome editing platform, as well as creating a new class of interventions to treat and prevent human diseases, and reduce greenhouse gas emissions to help reach global climate goals.

    Abstract

    Understanding microbial gene functions relies on the application of experimental genetics in cultured microorganisms. However, the vast majority of bacteria and archaea remain uncultured, precluding the application of traditional genetic methods to these organisms and their interactions. Here, we characterize and validate a generalizable strategy for editing the genomes of specific organisms in microbial communities. We apply environmental transformation sequencing (ET-seq), in which nontargeted transposon insertions are mapped and quantified following delivery to a microbial community, to identify genetically tractable constituents. Next, DNA-editing all-in-one RNA-guided CRISPR-Cas transposase (DART) systems for targeted DNA insertion into organisms identified as tractable by ET-seq are used to enable organism- and locus-specific genetic manipulation in a community context. Using a combination of ET-seq and DART in soil and infant gut microbiota, we conduct species- and site-specific edits in several bacteria, measure gene fitness in a nonmodel bacterium and enrich targeted species. These tools enable editing of microbial communities for understanding and control.

    The University of California is a public land-grant research university system in the U.S. state of California. The system is composed of the campuses at Berkeley, Davis, Irvine, Los Angeles, Merced, Riverside, San Diego, San Francisco, Santa Barbara, and Santa Cruz, along with numerous research centers and academic abroad centers. The system is the state’s land-grant university.

    The University of California was founded on March 23, 1868, and operated in Oakland before moving to Berkeley in 1873. Over time, several branch locations and satellite programs were established. In March 1951, the University of California began to reorganize itself into something distinct from its campus in Berkeley, with University of California President Robert Gordon Sproul staying in place as chief executive of the University of California system, while Clark Kerr became the first chancellor of The University of California-Berkeley and Raymond B. Allen became the first chancellor of The University of California-Los Angeles. However, the 1951 reorganization was stalled by resistance from Sproul and his allies, and it was not until Kerr succeeded Sproul as University of California President that University of California was able to evolve into a university system from 1957 to 1960. At that time, chancellors were appointed for additional campuses and each was granted some degree of greater autonomy.

    The University of California currently has 10 campuses, a combined student body of 285,862 students, 24,400 faculty members, 143,200 staff members and over 2.0 million living alumni. Its newest campus in Merced opened in fall 2005. Nine campuses enroll both undergraduate and graduate students; one campus, The University of California-San Francisco, enrolls only graduate and professional students in the medical and health sciences. In addition, the University of California Hastings College of the Law, located in San Francisco, is legally affiliated with University of California, but other than sharing its name is entirely autonomous from the rest of the system. Under the California Master Plan for Higher Education, the University of California is a part of the state’s three-system public higher education plan, which also includes the California State University system and the California Community Colleges system. University of California is governed by a Board of Regents whose autonomy from the rest of the state government is protected by the state constitution. The University of California also manages or co-manages three national laboratories for the U.S. Department of Energy: The DOE’s Lawrence Berkeley National Laboratory , The DOE’s Lawrence Livermore National Laboratory , and The Doe’s Los Alamos National Laboratory.

    Collectively, the colleges, institutions, and alumni of the University of California make it the most comprehensive and advanced post-secondary educational system in the world, responsible for nearly $50 billion per year of economic impact. Major publications generally rank most University of California campuses as being among the best universities in the world. Eight of the campuses, Berkeley, Davis, Irvine, Los Angeles, Santa Barbara, San Diego, Santa Cruz, and Riverside, are considered Public Ivies, making California the state with the most universities in the nation to hold the title. University of California campuses have large numbers of distinguished faculty in almost every academic discipline, with University of California faculty and researchers having won 71 Nobel Prizes as of 2021.

    In 1849, the state of California ratified its first constitution, which contained the express objective of creating a complete educational system including a state university. Taking advantage of the Morrill Land-Grant Acts, the California State Legislature established an Agricultural, Mining, and Mechanical Arts College in 1866. However, it existed only on paper, as a placeholder to secure federal land-grant funds.

    Meanwhile, Congregational minister Henry Durant, an alumnus of Yale University, had established the private Contra Costa Academy, on June 20, 1853, in Oakland, California. The initial site was bounded by Twelfth and Fourteenth Streets and Harrison and Franklin Streets in downtown Oakland (and is marked today by State Historical Plaque No. 45 at the northeast corner of Thirteenth and Franklin). In turn, the academy’s trustees were granted a charter in 1855 for a College of California, though the college continued to operate as a college preparatory school until it added college-level courses in 1860. The college’s trustees, educators, and supporters believed in the importance of a liberal arts education (especially the study of the Greek and Roman classics), but ran into a lack of interest in liberal arts colleges on the American frontier (as a true college, the college was graduating only three or four students per year).

    In November 1857, the college’s trustees began to acquire various parcels of land facing the Golden Gate in what is now Berkeley for a future planned campus outside of Oakland. But first, they needed to secure the college’s water rights by buying a large farm to the east. In 1864, they organized the College Homestead Association, which borrowed $35,000 to purchase the land, plus another $33,000 to purchase 160 acres (650,000 m^2) of land to the south of the future campus. The Association subdivided the latter parcel and started selling lots with the hope it could raise enough money to repay its lenders and also create a new college town. But sales of new homesteads fell short.

    Governor Frederick Low favored the establishment of a state university based upon The University of Michigan plan, and thus in one sense may be regarded as the founder of the University of California. At the College of California’s 1867 commencement exercises, where Low was present, Benjamin Silliman Jr. criticized Californians for creating a state polytechnic school instead of a real university. That same day, Low reportedly first suggested a merger of the already-functional College of California (which had land, buildings, faculty, and students, but not enough money) with the nonfunctional state college (which had money and nothing else), and went on to participate in the ensuing negotiations. On October 9, 1867, the college’s trustees reluctantly agreed to join forces with the state college to their mutual advantage, but under one condition—that there not be simply an “Agricultural, Mining, and Mechanical Arts College”, but a complete university, within which the assets of the College of California would be used to create a College of Letters (now known as the College of Letters and Science). Accordingly, the Organic Act, establishing the University of California, was introduced as a bill by Assemblyman John W. Dwinelle on March 5, 1868, and after it was duly passed by both houses of the state legislature, it was signed into state law by Governor Henry H. Haight (Low’s successor) on March 23, 1868. However, as legally constituted, the new university was not an actual merger of the two colleges, but was an entirely new institution which merely inherited certain objectives and assets from each of them. The University of California’s second president, Daniel Coit Gilman, opened its new campus in Berkeley in September 1873.

    Section 8 of the Organic Act authorized the Board of Regents to affiliate the University of California with independent self-sustaining professional colleges. “Affiliation” meant University of California and its affiliates would “share the risk in launching new endeavors in education.” The affiliates shared the prestige of the state university’s brand, and University of California agreed to award degrees in its own name to their graduates on the recommendation of their respective faculties, but the affiliates were otherwise managed independently by their own boards of trustees, charged their own tuition and fees, and maintained their own budgets separate from the University of California budget. It was through the process of affiliation that University of California was able to claim it had medical and law schools in San Francisco within a decade of its founding.

    In 1879, California adopted its second and current constitution, which included unusually strong language to ensure University of California’s independence from the rest of the state government. This had lasting consequences for the Hastings College of the Law, which had been separately chartered and affiliated in 1878 by an act of the state legislature at the behest of founder Serranus Clinton Hastings. After a falling out with his own handpicked board of directors, the founder persuaded the state legislature in 1883 and 1885 to pass new laws to place his law school under the direct control of the Board of Regents. In 1886, the Supreme Court of California declared those newer acts to be unconstitutional because the clause protecting University of California’s independence in the 1879 state constitution had stripped the state legislature of the ability to amend the 1878 act. To this day, the Hastings College of the Law remains an affiliate of University of California, maintains its own board of directors, and is not governed by the Regents.

    In contrast, Toland Medical College (founded in 1864 and affiliated in 1873) and later, the dental, pharmacy, and nursing schools in SF were affiliated with University of California through written agreements, and not statutes invested with constitutional importance by court decisions. In the early 20th century, the Affiliated Colleges (as they came to be called) began to agree to submit to the Regents’ governance during the term of President Benjamin Ide Wheeler, as the Board of Regents had come to recognize the problems inherent in the existence of independent entities that shared the University of California brand but over which University of California had no real control. While Hastings remained independent, the Affiliated Colleges were able to increasingly coordinate their operations with one another under the supervision of the University of California President and Regents, and evolved into the health sciences campus known today as the University of California-San Francisco.

    In August 1882, the California State Normal School (whose original normal school in San Jose is now San Jose State University) opened a second school in Los Angeles to train teachers for the growing population of Southern California. In 1887, the Los Angeles school was granted its own board of trustees independent of the San Jose school, and in 1919, the state legislature transferred it to University of California control and renamed it the Southern Branch of the University of California. In 1927, it became The University of California-Los Angeles; the “at” would be replaced with a comma in 1958.

    Los Angeles surpassed San Francisco in the 1920 census to become the most populous metropolis in California. Because Los Angeles had become the state government’s single largest source of both tax revenue and votes, its residents felt entitled to demand more prestige and autonomy for their campus. Their efforts bore fruit in March 1951, when UCLA became the first University of California site outside of Berkeley to achieve de jure coequal status with the Berkeley campus. That month, the Regents approved a reorganization plan under which both the Berkeley and Los Angeles campuses would be supervised by chancellors reporting to the University of California President. However, the 1951 plan was severely flawed; it was overly vague about how the chancellors were to become the “executive heads” of their campuses. Due to stubborn resistance from President Sproul and several vice presidents and deans—who simply carried on as before—the chancellors ended up as glorified provosts with limited control over academic affairs and long-range planning while the President and the Regents retained de facto control over everything else.

    Upon becoming president in October 1957, Clark Kerr supervised University of California’s rapid transformation into a true public university system through a series of proposals adopted unanimously by the Regents from 1957 to 1960. Kerr’s reforms included expressly granting all campus chancellors the full range of executive powers, privileges, and responsibilities which Sproul had denied to Kerr himself, as well as the radical decentralization of a tightly knit bureaucracy in which all lines of authority had always run directly to the President at Berkeley or to the Regents themselves. In 1965, UCLA Chancellor Franklin D. Murphy tried to push this to what he saw as its logical conclusion: he advocated for authorizing all chancellors to report directly to the Board of Regents, thereby rendering the University of California President redundant. Murphy wanted to transform University of California from one federated university into a confederation of independent universities, similar to the situation in Kansas (from where he was recruited). Murphy was unable to develop any support for his proposal, Kerr quickly put down what he thought of as “Murphy’s rebellion”, and therefore Kerr’s vision of University of California as a university system prevailed: “one university with pluralistic decision-making”.

    During the 20th century, University of California acquired additional satellite locations which, like Los Angeles, were all subordinate to administrators at the Berkeley campus. California farmers lobbied for University of California to perform applied research responsive to their immediate needs; in 1905, the Legislature established a “University Farm School” at Davis and in 1907 a “Citrus Experiment Station” at Riverside as adjuncts to the College of Agriculture at Berkeley. In 1912, University of California acquired a private oceanography laboratory in San Diego, which had been founded nine years earlier by local business promoters working with a Berkeley professor. In 1944, University of California acquired Santa Barbara State College from the California State Colleges, the descendants of the State Normal Schools. In 1958, the Regents began promoting these locations to general campuses, thereby creating The University of California-Santa Barbara (1958), The University of California-Davis (1959), The University of California-Riverside (1959), The University of California-San Diego (1960), and The University of California-San Francisco (1964). Each campus was also granted the right to have its own chancellor upon promotion. In response to California’s continued population growth, University of California opened two additional general campuses in 1965, with The University of California-Irvine opening in Irvine and The University of California-Santa Cruz opening in Santa Cruz. The youngest campus, The University of California-Merced opened in fall 2005 to serve the San Joaquin Valley.

    After losing campuses in Los Angeles and Santa Barbara to the University of California system, supporters of the California State College system arranged for the state constitution to be amended in 1946 to prevent similar losses from happening again in the future.

    The California Master Plan for Higher Education of 1960 established that University of California must admit undergraduates from the top 12.5% (one-eighth) of graduating high school seniors in California. Prior to the promulgation of the Master Plan, University of California was to admit undergraduates from the top 15%. University of California does not currently adhere to all tenets of the original Master Plan, such as the directives that no campus was to exceed total enrollment of 27,500 students (in order to ensure quality) and that public higher education should be tuition-free for California residents. Five campuses, Berkeley, Davis, Irvine, Los Angeles, and San Diego each have current total enrollment at over 30,000.

    After the state electorate severely limited long-term property tax revenue by enacting Proposition 13 in 1978, University of California was forced to make up for the resulting collapse in state financial support by imposing a variety of fees which were tuition in all but name. On November 18, 2010, the Regents finally gave up on the longstanding legal fiction that University of California does not charge tuition by renaming the Educational Fee to “Tuition.” As part of its search for funds during the 2000s and 2010s, University of California quietly began to admit higher percentages of highly accomplished (and more lucrative) students from other states and countries, but was forced to reverse course in 2015 in response to the inevitable public outcry and start admitting more California residents.

    As of 2019, University of California controls over 12,658 active patents. University of California researchers and faculty were responsible for 1,825 new inventions that same year. On average, University of California researchers create five new inventions per day.

    Seven of University of California’s ten campuses (UC Berkeley, UC Davis, UC Irvine, UCLA, UC San Diego, UC Santa Barbara, and UC Santa Cruz) are members of the Association of American Universities, an alliance of elite American research universities founded in 1900 at University of California’s suggestion. Collectively, the system counts among its faculty (as of 2002):

    389 members of the Academy of Arts and Sciences
    5 Fields Medal recipients
    19 Fulbright Scholars
    25 MacArthur Fellows
    254 members of the National Academy of Sciences
    91 members of the National Academy of Engineering
    13 National Medal of Science Laureates
    61 Nobel laureates.
    106 members of the Institute of Medicine

    Davis, Los Angeles, Riverside, and Santa Barbara all followed Berkeley’s example by aggregating the majority of arts, humanities, and science departments into a relatively large College of Letters and Science. Therefore, at Berkeley, Davis, Los Angeles, and Santa Barbara, their respective College of Letters and Science is by far the single largest academic unit on each campus. The College of Letters and Science at Los Angeles is the largest academic unit in the entire University of California system.

    Finally, Irvine is organized into 13 schools and San Francisco is organized into four schools, all of which are relatively narrow in scope.

    In 2006 the Scholarly Publishing and Academic Resources Coalition awarded the University of California the SPARC Innovator Award for its “extraordinarily effective institution-wide vision and efforts to move scholarly communication forward”, including the 1997 founding (under then University of California President Richard C. Atkinson) of the California Digital Library (CDL) and its 2002 launching of CDL’s eScholarship, an institutional repository. The award also specifically cited the widely influential 2005 academic journal publishing reform efforts of University of California faculty and librarians in “altering the marketplace” by publicly negotiating contracts with publishers, as well as their 2006 proposal to amend University of California’s copyright policy to allow open access to University of California faculty research. On July 24, 2013, the University of California Academic Senate adopted an Open Access Policy, mandating that all University of California faculty produced research with a publication agreement signed after that date be first deposited in University of California’s eScholarship open access repository.

    University of California system-wide research on the SAT exam found that, after controlling for familial income and parental education, so-called achievement tests known as the SAT II had 10 times more predictive ability of college aptitude than the SAT I.

    All University of California campuses except Hastings College of the Law are governed by the Regents of the University of California as required by the Constitution of the State of California. Eighteen regents are appointed by the governor for 12-year terms. One member is a student appointed for a one-year term. There are also seven ex officio members—the governor, lieutenant governor, speaker of the State Assembly, State Superintendent of Public Instruction, president and vice president of the alumni associations of University of California, and the University of California president. The Academic Senate, made up of faculty members, is empowered by the regents to set academic policies. In addition, the system-wide faculty chair and vice-chair sit on the Board of Regents as non-voting members.

    Originally, the president was the chief executive of the first campus, Berkeley. In turn, other University of California locations (with the exception of Hastings College of the Law) were treated as off-site departments of the Berkeley campus, and were headed by provosts who were subordinate to the president. In March 1951, the regents reorganized the university’s governing structure. Starting with the 1952–53 academic year, day-to-day “chief executive officer” functions for the Berkeley and Los Angeles campuses were transferred to chancellors who were vested with a high degree of autonomy, and reported as equals to University of California’s president. As noted above, the regents promoted five additional University of California locations to campuses and allowed them to have chancellors of their own in a series of decisions from 1958 to 1964, and the three campuses added since then have also been run by chancellors. In turn, all chancellors (again, with the exception of Hastings) report as equals to the University of California President. Today, the University of California Office of the President (UCOP) and the Office of the Secretary and Chief of Staff to the Regents of the University of California share an office building in downtown Oakland that serves as the University of California system’s headquarters.

    Kerr’s vision for University of California governance was “one university with pluralistic decision-making.” In other words, the internal delegation of operational authority to chancellors at the campus level and allowing nine other campuses to become separate centers of academic life independent of Berkeley did not change the fact that all campuses remain part of one legal entity. As a 1968 University of California centennial coffee table book explained: “Yet for all its campuses, colleges, schools, institutes, and research stations, it remains one University, under one Board of Regents and one president—the University of California.” University of California continues to take a “united approach” as one university in matters in which it inures to University of California’s advantage to do so, such as when negotiating with the legislature and governor in Sacramento. University of California continues to manage certain matters at the system wide level in order to maintain common standards across all campuses, such as student admissions, appointment and promotion of faculty, and approval of academic programs.

    The State of California currently (2021–2022) spends $3.467 billion on the University of California system, out of total University of California operating revenues of $41.6 billion. The “University of California Budget for Current Operations” lists the medical centers as the largest revenue source, contributing 39% of the budget, the federal government 11%, Core Funds (State General Funds, University of California General Funds, student tuition) 21%, private support (gifts, grants, endowments) 7% ,and Sales and Services at 21%. In 1980, the state funded 86.8% of the University of California budget. While state funding has somewhat recovered, as of 2019 state support still lags behind even recent historic levels (e.g. 2001) when adjusted for inflation.

    According to the California Public Policy Institute, California spends 12% of its General Fund on higher education, but that percentage is divided between the University of California, California State University and California Community Colleges. Over the past forty years, state funding of higher education has dropped from 18% to 12%, resulting in a drop in University of California’s per student funding from $23,000 in 2016 to a current $8,000 per year per student.

    In May 2004, University of California President Robert C. Dynes and CSU Chancellor Charles B. Reed struck a private deal, called the “Higher Education Compact”, with Governor Schwarzenegger. They agreed to slash spending by about a billion dollars (about a third of the university’s core budget for academic operations) in exchange for a funding formula lasting until 2011. The agreement calls for modest annual increases in state funds (but not enough to replace the loss in state funds Dynes and Schwarzenegger agreed to), private fundraising to help pay for basic programs, and large student fee hikes, especially for graduate and professional students. A detailed analysis of the Compact by the Academic Senate “Futures Report” indicated, despite the large fee increases, the university core budget did not recover to 2000 levels. Undergraduate student fees have risen 90% from 2003 to 2007. In 2011, for the first time in Univerchity of California’s history, student fees exceeded contributions from the State of California.

    The First District Court of Appeal in San Francisco ruled in 2007 that the University of California owed nearly $40 million in refunds to about 40,000 students who were promised that their tuition fees would remain steady, but were hit with increases when the state ran short of money in 2003.

    In September 2019, the University of California announced it will divest its $83 billion in endowment and pension funds from the fossil fuel industry, citing ‘financial risk’.

    At present, the University of California system officially describes itself as a “ten campus” system consisting of the campuses listed below.

    Berkeley
    Davis
    Irvine
    Los Angeles
    Merced
    Riverside
    San Diego
    San Francisco
    Santa Barbara
    Santa Cruz

    These campuses are under the direct control of the Regents and President. Only these ten campuses are listed on the official University of California letterhead.

    Although it shares the name and public status of the University of California system, the Hastings College of the Law is not controlled by the Regents or President; it has a separate board of directors and must seek funding directly from the Legislature. However, under the California Education Code, Hastings degrees are awarded in the name of the Regents and bear the signature of the University of California president. Furthermore, Education Code section 92201 states that Hastings “is affiliated with the University of California, and is the law department thereof”.

    Biology and geology and chemistry all worked together to make the present atmosphere.

    The “1. Great Oxygenation Event”, which occurred around 2.4 billion years ago, was one of the biggest transformations of our planet. Before it, there was practically no oxygen in the atmosphere; after, there was.

    Conventionally, the rise of oxygen is seen as life triumphantly terraforming a passive planet. But we’re learning now that Earth was an active participant, and it took two more big lifts of oxygen over the succeeding 2 billion years before it reached breathable levels. So which was more responsible for oxygen’s rise on Earth: the evolution of life or the evolution of the planet? Nature or nurture? And does the same answer apply to all of the rises of oxygen in Earth’s past?

    It’s a question beyond curiosity about our past, as it also affects how we might interpret signs of life on exoplanets.

    Alien Earth

    For almost half of our planet’s existence—the entire time before the Great Oxygenation Event, or GOE—Earth was effectively an alien planet. Apart from the obvious (the air was unbreathable), the oceans also lacked oxygen and were full of dissolved iron, while land was lethally irradiated by ultraviolet light, as the atmosphere lacked an ozone layer. Even the color palette was alien: Land lacked the reddish hues of dirt and the greens of vegetation, while the sky was pinkish-orange due to high methane levels.

    Life began in that alien environment, and at some point between 3.2 and 2.8 billion years ago, cyanobacteria began to use sunlight to split hydrogen from water, discarding oxygen as waste. That was a whopping 400 million to 800 million years before the GOE, roughly the same time that separates the present from the dawn of complex life.

    “Life turned on this set of reactions that can produce oxygen, but what we know from the geological record is that didn’t immediately result in huge amounts of oxygen in the atmosphere,” said Dr. Benjamin Mills of the University of Leeds.

    Clearly, the invention of oxygen-producing photosynthesis wasn’t enough by itself to oxygenate the atmosphere.

    Earth as oxygenator

    Earth loses about 90 tons of gas—mainly hydrogen and helium—to space every day. That’s tiny compared to the mass of our atmosphere, so there’s no cause for alarm. But before the GOE, hydrogen loss to space was so massive that it left an imbalance between isotopes of hydrogen today because hydrogen escapes more easily than deuterium, its heavier isotope. That imbalance shows Earth lost the equivalent of a quarter of the water that had filled its oceans due to hydrogen loss.

    “The mantle initially could have contained more water than it does now, and that water came out of the mantle initially in the form of hydrogen,” explained Professor Rajdeep Dasgupta of Rice University.

    Losing hydrogen from H2O but keeping the oxygen pushed Earth toward an oxidizing environment, the same way it was developed on Mars. Mars has just enough oxygen, which was left behind after the hydrogen from its water leaked into space, to rust its surface red,

    “There is a net oxidation of the planet, including the atmosphere, including the crust and the mantle through time,” Dasgupta said about Earth.

    Mellowing Earth

    On Earth, with its more active geology, there were many additional things for the oxygen to react with. “Oxygen buildup in the atmosphere is not just how you create oxygen; it’s also about how you might or might not destroy oxygen,” explained Dasgupta.

    Earth’s early atmosphere was stuffed with oxygen-consuming (“reducing”) gases, like hydrogen, carbon monoxide, hydrogen sulfide, sulfur dioxide, and methane. These were continuously emitted by volcanoes, as well as microbes and seawater reacting with lava. Hydrogen from seawater-lava reactions may have consumed more than 70 million tons of oxygen every year. The oceans were also full of dissolved iron that would rust on contact with any dissolved oxygen, consuming it.

    Collectively, these gases soaked up the oxygen as soon as it was made. “You don’t just need to make enough to fill the atmosphere with oxygen; you need to make enough to fill it with oxygen thousands and thousands of times over to keep it there,” said Mills.

    The cooling planet was crucial for making Earth friendlier to oxygen. Once Earth was cool enough, its crust began to move around the globe in rigid plates that collided, sending material plunging into the mantle and helping to cool the planet’s interior further.

    As a result, Earth transformed from a water world spotted with volcanic islands into a world with continents and mountains on thick continental crust.

    Thickening the crust increased the depth where magma was stored before erupting, thereby increasing the pressure on it. That simple change altered the chemistry of molten rock and thus the chemistry of gases released by volcanoes. “In one case, you will get reduced gases when the crust is thin. In another case, you will get more oxidized gases when the crust is thick,” Dasgupta told Ars. So the production of oxygen-eating gases dropped as continents grew.

    Death frees oxygen

    Before continents, a lack of nutrients like phosphorous in ocean water may have limited the abundance of life to less than 7 percent of living mass today. This kept the population of cyanobacteria low, suppressing the production of oxygen. But as continents grew, erosion delivered more nutrients to the oceans, and as the chemistry of lavas changed in concert with growing continents, those nutrients came from increasingly phosphorous-rich rocks, boosting the amount of life the planet could support.

    As the life in the oceans flourished, it boosted a process called “the carbon pump.” Today, the entire plankton population in the surface layer of the world’s oceans is murdered by planktonic grazers and viruses every few days. While much of the carbon in that carnage is recycled into new life, some settles onto the seabed where it gets buried, a process known as the “biological carbon pump.” With the exception of grazers, which didn’t exist yet, something similar was going on in early Earth.

    That organic carbon also reacts with oxygen, making CO2. So for oxygen to build up in the atmosphere, organic carbon must be buried. To put it another way, carbon burial promotes the rise of oxygen.

    As continents grew, so did the supply of iron washed into oceans, which bound to organic carbon, protecting it from being recycled by microbes until it was safely buried away, thus enhancing the carbon burial. Larger continents provided more space for sedimentary basins that also buried organic carbon, helping oxygen to rise.

    Wobbly transition

    With all these factors at work, it’s perhaps unsurprising that the GOE wasn’t a simple off-on switch. The rock record shows occasional “whiffs” of oxygen began hundreds of millions of years before the GOE, building to a climactic switch over to oxygen in the atmosphere, with oxygen levels continuing to wobble for another 200 million years afterward.

    “If that flux [of oxygen-eating gases] is decreasing over time, you’re approaching a switch point where eventually it flips over,” said Professor Ariel Anbar of Arizona State University. “As you approach that switch point, the system should become less and less stable. What was an overwhelming amount of reductant becomes a ‘just enough’ amount of reductant.”

    Flipping the oxygen state of the planet plunged it into crisis. “You’re keeping the Earth warm because of the good graces of methane greenhouse, and then along come whiffs of oxygen… and you start to erode that greenhouse,” said Anbar. “So you end up creating glacial episodes.”

    Consequently, Earth plunged into a series of planet-wide “Snowball Earth” ice ages right after the GOE and continuing for some 220 million years.

    Bored and unfulfilled

    The GOE changed the composition of the Earth by creating some 3,000 oxidized minerals that didn’t exist before. Sunlight in the stratosphere converted some oxygen into ozone, forming a layer that shielded land from sterilizing ultraviolet radiation. Methane oxidized to CO2, turning the sky blue; combined with the CO2 emitted by volcanoes, the planet had enough greenhouse gas to keep it from freezing. The dissolved iron in the oceans mostly precipitated into iron ore that is mined today, and oxygen reacted with hydrogen to make water, slowing its escape to space and preserving Earth’s oceans. A new kind of cell evolved—eukaryotes, many of which have a metabolism that relies on oxygen—that eventually enabled complex life.

    And yet the promise of breathable oxygen remained unfulfilled; it remained a mere 1 percent of present levels.

    It wasn’t the supply of oxygen-eating volcanic gases that kept oxygen in check, as geochemical data show that those diminished steadily. If they were controlling oxygen levels, oxygen should have been rising.

    “I think it’s telling us something about what’s really limiting the biosphere,” said Anbar, “and it’s not the availability of oxygen, and it’s not really the availability of energy. There’s plenty of energy at the surface. Life figured out pretty early how to capture it up to limits, which are set by nutrient availability.”

    This low-oxygen state lasted a billion and a half years, coinciding with a period of muted geological activity dubbed the “Boring Billion.” Although the causes and consequences of this underwhelming period are elusive, there seems to have been a long-lived supercontinent with limited mountain-building activity. Whatever mountains that once existed were worn to hills, their nutrients weathered out or stranded in a stable landscape, unable to feed sea life. And although the ocean’s surface stayed oxygenated, its depths remained anoxic and dissolved iron began to build up again.

    “You seem to have sort of a return to more reducing conditions in the oceans than before,” said Anbar. “It’s hard to have a lot of iron dissolve in seawater if you have any oxygen around,” he said.

    Second verse, kinda the same as the first

    Then, a billion and a half years after the GOE, Earth had its second big increase in oxygen levels, called the “2. Neoproterozoic Oxygenation Event,” or “NOE,” which occurred between about 800 million and 500 million years ago and took oxygen to about half of modern levels.

    Although the details are debated, the NOE was spookily similar to the GOE, with big fluctuations in oxygen for some 300 million years. Like the GOE, it coincided with major evolutionary advances in life, as well as a change in the style of plate tectonics; it, too, was followed by Snowball Earth glaciations.

    Again, fluctuations in oxygen reflect Earth at another tipping point. “You enter this period of instability, which seems to be a natural thing that happens when the ocean is about to become well-oxygenated,” said Mills. “If you have an ocean that’s oxygenated, you suddenly change a whole bunch of stuff. You change what minerals are going to form [and] you pull phosphorus out of the ocean. So you can have quite a dynamic shift when you oxygenate or deoxygenate the oceans.”

    Could new lifeforms have been the driver of the NOE?

    There’s a remarkable diversification of life then, and “sterane,” a biomarker for eukaryotic cells, shows they became more abundant at the time. The earliest animals evolved around then as well. Professor Tim Lenton of the University of Exeter has suggested that evolution led to more efficient carbon burial as the new lifeforms were larger, so they sank to the seabed faster, preserving more carbon from being recycled. Although that idea is controversial, there’s also evidence that algae may have begun colonizing land at that time. If so, the organic acids the algae must have used to extract nutrients from rock would have enhanced the supply of nutrients to the sea.

    Carbon isotopes show a big increase in organic carbon burial at this time, which would have encouraged oxygen to rise. The algal rock weathering and extra carbon burial would also have cooled the climate, possibly triggering the snowball glaciations.

    Cold slabs

    But life may not be the entire story, as Earth was transforming itself at that time of the NOE.

    Plate tectonics ended the “Boring Billion” by rifting the “Rodinia” supercontinent into several smaller continents scattered across the tropics.

    Mountain building was back in fashion, and volcanoes erupted with renewed vigor as continents bulldozed over oceanic plates.

    Earth was beginning a new style of plate tectonics, with colder plates producing a new suite of high-pressure rocks called “blueschists” as they plunged, or “subducted,” into the mantle. Earlier in Earth’s history, when the planet was hotter, the majority of plates melted once they entered the mantle, but by the NOE, the planet had cooled enough for most downward-moving plates—dubbed “slabs”—not to melt.

    “If you go to cold subduction zones, slab melting is precluded. You are only looking at the dehydration of the slab,” said Dasgupta. “In one case, it’s hot fluid, and in another case, it’s hydrous magma.”

    This new style of plate tectonics resulted in steadier, more sustained plunging of plates into the mantle, which increased the amount of continental crust and carbon sent deep into Earth’s interior. Crucially, this thickened mountain belts. The resulting erosion supplied more nutrients and iron to the oceans, which boosted biological activity, carbon burial, and oxygen rise.

    Once again, Earth careened on a roller coaster of climate and nutrient extremes. Two “Snowball Earth” glaciations ensued, with ice covering most of the planet for tens of millions of years, each followed by hot “super-greenhouse” conditions that flushed torrents of ice-pulverized rock nutrients into the oceans.

    Oxygen continued to fluctuate long afterward, with one low-oxygen episode triggering the oldest documented mass extinction of early animals about 550 million years ago. Despite that, life continued to evolve more energy-demanding lifestyles favored by higher oxygen levels, with organisms building larger bodies, burrowing into the seabed, and moving around under their own power.

    “The production of oxygen allows the type of life to change radically,” said Anbar. “Because suddenly… you have a lot more energy available, you can evolve aerobic metabolism, which is a much more energy-rich metabolism. You can then start doing more complicated things… evolution can figure out more complicated tricks.”

    Third time’s a charm

    Earth’s final oxygen rise, the “3. Paleozoic Oxygenation Event” or “POE,” began about 470 million years ago. It has a much clearer cause: the evolution of land plants. “Land plants certainly increased the rate of oxygen production, and we’re pretty convinced now that it was their evolution that bumps up oxygen levels to a level that we could breathe,” said Mills.

    The reason, again, comes down to the burial of organic carbon.

    “Plants have to build their bodies differently to marine algae and bacteria because they’ve got to stay upright,” explained Mills. That requires more carbon-rich bodies. “They can just start to bury more carbon. You’ve got a tenfold increase in the carbon-richness of the material that you’re burying,” said Mills.

    In a faint echo of earlier oxygenation events, the POE brought another severe glaciation. Although it was far shorter and milder than a “Snowball” glaciation, sea levels dropped drastically, and large parts of the oceans lost their oxygen again, causing a major mass extinction. But the glaciation was comparatively brief, and soon, modernish levels of oxygen supported energetic life like fish and land animals.

    But higher oxygen levels also brought fire, and fire limits oxygen.

    The oldest fragments of charcoal have been found in rocks that formed about 430 million years ago. Since fire can’t happen if oxygen is below 16 percent of the atmosphere, oxygen must have been higher by then. Conversely, the absence of charcoal, or “charcoal gaps,” imply that oxygen crashed below that level a few times since. That happened around 390 million years ago and again right after land plants were devastated by the end-Permian mass extinction 252 million years ago.

    “Oxygen levels have most likely been falling since the Cretaceous, and part of that is due to the change in makeup of the terrestrial biosphere, which just means it’s much more prone to fire than it used to be,” said Mills.

    Fire consumes oxygen and keeps vegetation in check, Mills told Ars. “If there were no wildfires at all, you’d have double the amount of productivity through forests, so they’re quite limiting,” he said.

    Was life or Earth more responsible for oxygen in the atmosphere?

    “We geobiologists tend to get all distracted by all the biology, and then we get lost in all the chemistry, too,” said Anbar. “It’s all sitting on a planet, and the planet is really big, and it moves slowly, but it’s inexorable.”

    Theoretically, “without any involvement of life at all, simply through whole-planet-scale geochemical cycling and tectonics, one could give rise to higher oxygen in the atmosphere of our planet with time,” said Dasgupta.

    This means that if oxygen is detected in the atmosphere of another planet, it may or may not indicate life: “It’s certainly not a yes-or-no,” said Mills. “But anything approaching Earth-like levels of oxygen in the atmosphere, I would say definitely.” That’s because photosynthesis was probably necessary for Earth’s current oxygen levels: “For Earth to have a lot of oxygen, I think you do need to have a photosynthetic biosphere,” said Anbar.

    But was it sufficient?

    “It’s at least plausible to argue had the mantle not evolved… that an O2-rich atmosphere would not have emerged,” said Anbar.

    “You absolutely needed life to begin the process, but in order to have that process run to completion, you needed solid Earth changes,” agreed Mills.

    In the “Gaia Hypothesis,” James Lovelock and Lynn Margulis argued that life “acquired control” of the planetary environment leading to “homeostasis by and for the biosphere.” But Earth’s oxygenation shows that the Earth was just as much in control of the planetary environment and the evolution of life, so the roles of the biosphere and geosphere are inseparable:

    Earth is a living planet. it is alive in a very real sense and how living planets evolve is an open question.

    Ars Technica was founded in 1998 when Founder & Editor-in-Chief Ken Fisher announced his plans for starting a publication devoted to technology that would cater to what he called “alpha geeks”: technologists and IT professionals. Ken’s vision was to build a publication with a simple editorial mission: be “technically savvy, up-to-date, and more fun” than what was currently popular in the space. In the ensuing years, with formidable contributions by a unique editorial staff, Ars Technica became a trusted source for technology news, tech policy analysis, breakdowns of the latest scientific advancements, gadget reviews, software, hardware, and nearly everything else found in between layers of silicon.

    Ars Technica innovates by listening to its core readership. Readers have come to demand devotedness to accuracy and integrity, flanked by a willingness to leave each day’s meaningless, click-bait fodder by the wayside. The result is something unique: the unparalleled marriage of breadth and depth in technology journalism. By 2001, Ars Technica was regularly producing news reports, op-eds, and the like, but the company stood out from the competition by regularly providing long thought-pieces and in-depth explainers.

    And thanks to its readership, Ars Technica also accomplished a number of industry leading moves. In 2001, Ars launched a digital subscription service when such things were non-existent for digital media. Ars was also the first IT publication to begin covering the resurgence of Apple, and the first to draw analytical and cultural ties between the world of high technology and gaming. Ars was also first to begin selling its long form content in digitally distributable forms, such as PDFs and eventually eBooks (again, starting in 2001).

    Study looks at dynamics of how warming may affect capture in soil near trees and other plants.

    1
    Ph.D. candidate Nikhil Chari (left) and Assistant Professor of Organismic and Evolutionary Biology Benton Taylor collect root exudates.

    The leaves of trees and plants have been called the Earth’s lungs because they take in carbon dioxide and give out oxygen. But beneath the soil’s surface, the roots of those plants are doing their bit for regulating the climate, facilitating the storage of carbon in the soil. But small changes in these processes can have considerable effects, as researchers in the Department of Organismic and Evolutionary Biology reveal in a study in Nature Geoscience [below].

    Roots release exudates — organic carbon compounds — that interact with bacteria, fungi, and other soil elements to make its nutrients more accessible to the plant. “In its most basic sense, root exudates are materials that get put out into the soil to help the microbial community convert material that’s already in the soil into forms that the root can then take up and use,” explained Benton Taylor, assistant professor in OEB and the study’s senior author. “For example, root exudates can prime the soil microbial community to convert nitrogen to what’s called mineralized nitrogen, a form that’s usable for the plant.”

    These exudates also interact with mineral-associated organic matter (or MAOM), where carbon gets bound to clays and other soil minerals, essentially capturing and storing it.

    “MAOM” has been viewed as “essentially stable over decadal timescales,” according to Taylor, but the researchers found that changes in the rate and composition of root exudation can result in short-term changes to MAOM — and, thus ultimately, to the soil’s ability to store carbon.

    “Root exudates are important regulators of soil carbon storage,” said Nikhil R. Chari, a Harvard Griffin Graduate School of Arts and Sciences student in OEB. Chari, the study’s lead author, points out that these exudates “are already small molecules so they can directly affect the kind of microscopic soil carbon that makes up MAOM.”

    “If warming or other climate-change drivers change the types of exudates that are coming out on the plant, how is that going to affect these pools of carbon that would normally be in the soil for a long time?” Chari added.

    To simulate different root exudates, the researchers fabricated three different exudate “cocktails” of simple sugars, amino acids, and organic acids and pumped them into soils using artificial roots. In a step distinguishing their experiment from prior work, the researchers performed these tests using intact soil cores from the Harvard Forest, rather than artificial or homogenized soil, preserving native soil biology, structure, and heterogeneity.

    What they found showed the resilience of the soil — up to a point. “When we pumped just a little bit of exudate into the soil, the MAOM carbon pool did grow. It did accumulate bit by bit over time,” said Taylor. “When we pumped more exudates into the soil, more of those exudates made it into the MAOM pool — but the MAOM carbon pool didn’t get bigger. It just increased the rate at which MAOM was also being lost.”

    “Our data suggests that this loss will also increase the release of carbon out of these long-term storage pools, and that we won’t necessarily see this long-term accumulation of stable soil carbon if exudation rates increase,” said Taylor.

    This limitation has real-world implications. “If you think about plants having more carbon available to them as CO2 concentrations in the atmosphere rise, you might expect changes in their ability and their propensity to release carbon out of their roots,” said Taylor.

    The researchers also found that their exudate cocktails had differing effects on the MAOM. The organic and amino acids resulted in a lower rate of MAOM formation — and, ultimately, a net carbon accumulation. However, the simple sugar exudates produced a greater MAOM turnover — the equivalent of giving soil microbes a “sugar high,” Taylor suggested.

    “This gives us an idea of how these different exudate compounds will affect soil carbon dynamics,” said Chari. “What we really want to figure out is how these profiles, the rate of the carbon going into the soil and the types of carbon, like sugars or amino acids or organic acids coming in from the plant, are changing.”

    The team, he said, is working with other researchers around the world on the effects of warming and elevated carbon dioxide to “be able to pair the actual changes coming out of the plant with how we see these different exudates affecting soil carbon dynamics,” said Chari. “This would allow us to better predict soil carbon dynamics in the future.”

    Harvard University campus

    Harvard University is the oldest institution of higher education in the United States, established in 1636 by vote of the Great and General Court of the Massachusetts Bay Colony. It was named after the College’s first benefactor, the young minister John Harvard of Charlestown, who upon his death in 1638 left his library and half his estate to the institution. A statue of John Harvard stands today in front of University Hall in Harvard Yard, and is perhaps the University’s best-known landmark.

    Harvard University has 12 degree-granting Schools in addition to the Radcliffe Institute for Advanced Study. The University has grown from nine students with a single master to an enrollment of more than 20,000 degree candidates including undergraduate, graduate, and professional students. There are more than 360,000 living alumni in the U.S. and over 190 other countries.

    The Massachusetts colonial legislature, the General Court, authorized Harvard University’s founding. In its early years, Harvard College primarily trained Congregational and Unitarian clergy, although it has never been formally affiliated with any denomination. Its curriculum and student body were gradually secularized during the 18th century, and by the 19th century, Harvard University (US) had emerged as the central cultural establishment among the Boston elite. Following the American Civil War, President Charles William Eliot’s long tenure (1869–1909) transformed the college and affiliated professional schools into a modern research university; Harvard became a founding member of the Association of American Universities in 1900. James B. Conant led the university through the Great Depression and World War II; he liberalized admissions after the war.

    The university is composed of ten academic faculties plus the Radcliffe Institute for Advanced Study. Arts and Sciences offers study in a wide range of academic disciplines for undergraduates and for graduates, while the other faculties offer only graduate degrees, mostly professional. Harvard has three main campuses: the 209-acre (85 ha) Cambridge campus centered on Harvard Yard; an adjoining campus immediately across the Charles River in the Allston neighborhood of Boston; and the medical campus in Boston’s Longwood Medical Area. Harvard University’s endowment is valued at $41.9 billion, making it the largest of any academic institution. Endowment income helps enable the undergraduate college to admit students regardless of financial need and provide generous financial aid with no loans The Harvard Library is the world’s largest academic library system, comprising 79 individual libraries holding about 20.4 million items.

    Harvard University has more alumni, faculty, and researchers who have won Nobel Prizes (161) and Fields Medals (18) than any other university in the world and more alumni who have been members of the U.S. Congress, MacArthur Fellows, Rhodes Scholars (375), and Marshall Scholars (255) than any other university in the United States. Its alumni also include eight U.S. presidents and 188 living billionaires, the most of any university. Fourteen Turing Award laureates have been Harvard affiliates. Students and alumni have also won 10 Academy Awards, 48 Pulitzer Prizes, and 108 Olympic medals (46 gold), and they have founded many notable companies.

    Harvard University was established in 1636 by vote of the Great and General Court of the Massachusetts Bay Colony. In 1638, it acquired British North America’s first known printing press. In 1639, it was named Harvard College after deceased clergyman John Harvard, an alumnus of the University of Cambridge(UK) who had left the school £779 and his library of some 400 volumes. The charter creating the Harvard Corporation was granted in 1650.

    A 1643 publication gave the school’s purpose as “to advance learning and perpetuate it to posterity, dreading to leave an illiterate ministry to the churches when our present ministers shall lie in the dust.” It trained many Puritan ministers in its early years and offered a classic curriculum based on the English university model—many leaders in the colony had attended the University of Cambridge—but conformed to the tenets of Puritanism. Harvard University has never affiliated with any particular denomination, though many of its earliest graduates went on to become clergymen in Congregational and Unitarian churches.

    Increase Mather served as president from 1681 to 1701. In 1708, John Leverett became the first president who was not also a clergyman, marking a turning of the college away from Puritanism and toward intellectual independence.

    19th century

    In the 19th century, Enlightenment ideas of reason and free will were widespread among Congregational ministers, putting those ministers and their congregations in tension with more traditionalist, Calvinist parties. When Hollis Professor of Divinity David Tappan died in 1803 and President Joseph Willard died a year later, a struggle broke out over their replacements. Henry Ware was elected to the Hollis chair in 1805, and the liberal Samuel Webber was appointed to the presidency two years later, signaling the shift from the dominance of traditional ideas at Harvard to the dominance of liberal, Arminian ideas.

    Charles William Eliot, president 1869–1909, eliminated the favored position of Christianity from the curriculum while opening it to student self-direction. Though Eliot was the crucial figure in the secularization of American higher education, he was motivated not by a desire to secularize education but by Transcendentalist Unitarian convictions influenced by William Ellery Channing and Ralph Waldo Emerson.

    20th century

    In the 20th century, Harvard University’s reputation grew as a burgeoning endowment and prominent professors expanded the university’s scope. Rapid enrollment growth continued as new graduate schools were begun and the undergraduate college expanded. Radcliffe College, established in 1879 as the female counterpart of Harvard College, became one of the most prominent schools for women in the United States. Harvard University became a founding member of the Association of American Universities in 1900.

    The student body in the early decades of the century was predominantly “old-stock, high-status Protestants, especially Episcopalians, Congregationalists, and Presbyterians.” A 1923 proposal by President A. Lawrence Lowell that Jews be limited to 15% of undergraduates was rejected, but Lowell did ban blacks from freshman dormitories.

    President James B. Conant reinvigorated creative scholarship to guarantee Harvard University’s preeminence among research institutions. He saw higher education as a vehicle of opportunity for the talented rather than an entitlement for the wealthy, so Conant devised programs to identify, recruit, and support talented youth. In 1943, he asked the faculty to make a definitive statement about what general education ought to be, at the secondary as well as at the college level. The resulting Report, published in 1945, was one of the most influential manifestos in 20th century American education.

    Between 1945 and 1960, admissions were opened up to bring in a more diverse group of students. No longer drawing mostly from select New England prep schools, the undergraduate college became accessible to striving middle class students from public schools; many more Jews and Catholics were admitted, but few blacks, Hispanics, or Asians. Throughout the rest of the 20th century, Harvard became more diverse.

    Harvard University’s graduate schools began admitting women in small numbers in the late 19th century. During World War II, students at Radcliffe College (which since 1879 had been paying Harvard University professors to repeat their lectures for women) began attending Harvard University classes alongside men. Women were first admitted to the medical school in 1945. Since 1971, Harvard University has controlled essentially all aspects of undergraduate admission, instruction, and housing for Radcliffe women. In 1999, Radcliffe was formally merged into Harvard University.

    21st century

    Drew Gilpin Faust, previously the dean of the Radcliffe Institute for Advanced Study, became Harvard University’s first woman president on July 1, 2007. She was succeeded by Lawrence Bacow on July 1, 2018.

    Scientists find new route in bacteria to decarbonize industry. The discovery could reduce greenhouse gas emissions from the manufacturing of fuels, drugs, and chemicals.

    A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley has engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.

    The advance – which was recently announced in the journal Nature [below]– uses bacteria to combine natural enzymatic reactions with a new-to-nature reaction called the “carbene transfer reaction.” This work could also one day help reduce industrial emissions because it offers sustainable alternatives to chemical manufacturing processes that typically rely on fossil fuels.

    “What we showed in this paper is that we can synthesize everything in this reaction – from natural enzymes to carbenes – inside the bacterial cell. All you need to add is sugar and the cells do the rest,” said Jay Keasling, a principal investigator of the study and CEO of the Department of Energy’s Joint BioEnergy Institute (JBEI).

    Carbenes are highly reactive carbon-based chemicals that can be used in many different types of reactions. For decades, scientists have wanted to use carbene reactions in the manufacturing of fuels and chemicals, and in drug discovery and synthesis.

    But these carbene processes could only be carried out in small batches via test tubes and required expensive chemical substances to drive the reaction.

    In the new study, the researchers replaced expensive chemical reactants with natural products that can be produced by an engineered strain of the bacteria Streptomyces. Because the bacteria use sugar to produce chemical products through cellular metabolism, “this work enables us to perform the carbene chemistry without toxic solvents or toxic gases typically used in chemical synthesis,” said first author Jing Huang, a Berkeley Lab postdoctoral researcher in the Keasling Lab. “This biological process is much more environmentally friendly than the way chemicals are synthesized today,” Huang said.

    During experiments at JBEI, the researchers observed the engineered bacterium as it metabolized and converted sugars into the carbene precursor and the alkene substrate. The bacterium also expressed an evolved P450 enzyme that used those chemicals to produce cyclopropanes, high-energy molecules that could potentially be used in the sustainable production of novel bioactive compounds and advanced biofuels. “We can now perform these interesting reactions inside the bacterial cell. The cells produce all of the reagents and the cofactors, which means that you can scale this reaction to very large scales” for mass manufacturing, Keasling said.

    Recruiting bacteria to synthesize chemicals could also play an integral role in reducing carbon emissions, Huang said. According to other Berkeley Lab researchers, close to 50% of greenhouse gas emissions come from the production of chemicals, iron and steel, and cement. Limiting global warming to 1.5 degrees Celsius above pre-industrial levels will require severely cutting greenhouse gas emissions in half by 2030, says a recent report by the Intergovernmental Panel on Climate Change.

    Huang said that while this fully integrated system can be envisioned for a large number of carbene donor molecules and alkene substrates, it is not yet ready for commercialization.

    “For every new advance, someone needs to take the first step. And in science, it can take years before you succeed. But you have to keep trying – we can’t afford to give up. I hope our work will inspire others to continue searching for greener, sustainable biomanufacturing solutions,” Huang said.

    The University of California-Berkeley is a public land-grant research university in Berkeley, California. Established in 1868 as the state’s first land-grant university, it was the first campus of the University of California system and a founding member of the Association of American Universities . Its 14 colleges and schools offer over 350 degree programs and enroll some 31,000 undergraduate and 12,000 graduate students. Berkeley is ranked among the world’s top universities by major educational publications.

    Berkeley hosts many leading research institutes, including the Mathematical Sciences Research Institute and the Space Sciences Laboratory. It founded and maintains close relationships with three national laboratories at The DOE’s Lawrence Berkeley National Laboratory, The DOE’s Lawrence Livermore National Laboratory and The DOE’s Los Alamos National Lab, and has played a prominent role in many scientific advances, from the Manhattan Project and the discovery of 16 chemical elements to breakthroughs in computer science and genomics. Berkeley is also known for student activism and the Free Speech Movement of the 1960s.

    Berkeley alumni and faculty count among their ranks 110 Nobel laureates (34 alumni), 25 Turing Award winners (11 alumni), 14 Fields Medalists, 28 Wolf Prize winners, 103 MacArthur “Genius Grant” recipients, 30 Pulitzer Prize winners, and 19 Academy Award winners. The university has produced seven heads of state or government; five chief justices, including Chief Justice of the United States Earl Warren; 21 cabinet-level officials; 11 governors; and 25 living billionaires. It is also a leading producer of Fulbright Scholars, MacArthur Fellows, and Marshall Scholars. Berzerkeley alumni, widely recognized for their entrepreneurship, have founded many notable companies.

    Berkeley’s athletic teams compete in Division I of the NCAA, primarily in the Pac-12 Conference, and are collectively known as the California Golden Bears. The university’s teams have won 107 national championships, and its students and alumni have won 207 Olympic medals.

    Made possible by President Lincoln’s signing of the Morrill Act in 1862, the University of California was founded in 1868 as the state’s first land-grant university by inheriting certain assets and objectives of the private College of California and the public Agricultural, Mining, and Mechanical Arts College. Although this process is often incorrectly mistaken for a merger, the Organic Act created a “completely new institution” and did not actually merge the two precursor entities into the new university. The Organic Act states that the “University shall have for its design, to provide instruction and thorough and complete education in all departments of science, literature and art, industrial and professional pursuits, and general education, and also special courses of instruction in preparation for the professions”.

    Ten faculty members and 40 students made up the fledgling university when it opened in Oakland in 1869. Frederick H. Billings, a trustee of the College of California, suggested that a new campus site north of Oakland be named in honor of Anglo-Irish philosopher George Berkeley. The university began admitting women the following year. In 1870, Henry Durant, founder of the College of California, became its first president. With the completion of North and South Halls in 1873, the university relocated to its Berkeley location with 167 male and 22 female students.

    Beginning in 1891, Phoebe Apperson Hearst made several large gifts to Berkeley, funding a number of programs and new buildings and sponsoring, in 1898, an international competition in Antwerp, Belgium, where French architect Émile Bénard submitted the winning design for a campus master plan.

    20th century

    In 1905, the University Farm was established near Sacramento, ultimately becoming the University of California-Davis. In 1919, Los Angeles State Normal School became the southern branch of the University, which ultimately became the University of California-Los Angeles. By 1920s, the number of campus buildings had grown substantially and included twenty structures designed by architect John Galen Howard.

    In 1917, one of the nation’s first ROTC programs was established at Berkeley and its School of Military Aeronautics began training pilots, including Gen. Jimmy Doolittle. Berkeley ROTC alumni include former Secretary of Defense Robert McNamara and Army Chief of Staff Frederick C. Weyand as well as 16 other generals. In 1926, future fleet admiral Chester W. Nimitz established the first Naval ROTC unit at Berkeley.

    In the 1930s, Ernest Lawrence helped establish the Radiation Laboratory (now DOE’s Lawrence Berkeley National Laboratory) and invented the cyclotron, which won him the Nobel physics prize in 1939. Using the cyclotron, Berkeley professors and Berkeley Lab researchers went on to discover 16 chemical elements—more than any other university in the world. In particular, during World War II and following Glenn Seaborg’s then-secret discovery of plutonium, Ernest Orlando Lawrence’s Radiation Laboratory began to contract with the U.S. Army to develop the atomic bomb. Physics professor J. Robert Oppenheimer was named scientific head of the Manhattan Project in 1942. Along with the Lawrence Berkeley National Laboratory, Berkeley founded and was then a partner in managing two other labs, The Doe’s Los Alamos National Laboratory (1943) and The DOE’s Lawrence Livermore National Laboratory (1952).

    By 1942, the American Council on Education ranked Berkeley second only to Harvard University in the number of distinguished departments.

    In 1952, the University of California reorganized itself into a system of semi-autonomous campuses, with each campus given its own chancellor, and Clark Kerr became Berkeley’s first Chancellor, while Sproul remained in place as the President of the University of California.

    Berkeley gained a worldwide reputation for political activism in the 1960s. In 1964, the Free Speech Movement organized student resistance to the university’s restrictions on political activities on campus—most conspicuously, student activities related to the Civil Rights Movement. The arrest in Sproul Plaza of Jack Weinberg, a recent Berkeley alumnus and chair of Campus CORE, in October 1964, prompted a series of student-led acts of formal remonstrance and civil disobedience that ultimately gave rise to the Free Speech Movement, which movement would prevail and serve as precedent for student opposition to America’s involvement in the Vietnam War.

    In 1982, the Mathematical Sciences Research Institute (MSRI) was established on campus with support from the National Science Foundation and at the request of three Berzerkeley mathematicians — Shiing-Shen Chern, Calvin Moore and Isadore M. Singer. The institute is now widely regarded as a leading center for collaborative mathematical research, drawing thousands of visiting researchers from around the world each year.

    21st century

    In the current century, Berkeley has become less politically active and more focused on entrepreneurship and fundraising, especially for STEM disciplines.

    Modern Berkeley students are less politically radical, with a greater percentage of moderates and conservatives than in the 1960s and 70s. Democrats outnumber Republicans on the faculty by a ratio of 9:1. On the whole, Democrats outnumber Republicans on American university campuses by a ratio of 10:1.

    In 2007, the Energy Biosciences Institute was established with funding from BP and Stanley Hall, a research facility and headquarters for the California Institute for Quantitative Biosciences, opened. The next few years saw the dedication of the Center for Biomedical and Health Sciences, funded by a lead gift from billionaire Li Ka-shing; the opening of Sutardja Dai Hall, home of the Center for Information Technology Research in the Interest of Society; and the unveiling of Blum Hall, housing the Blum Center for Developing Economies. Supported by a grant from alumnus James Simons, the Simons Institute for the Theory of Computing was established in 2012. In 2014, Berkeley and its sister campus, University of California-San Fransisco, established the Innovative Genomics Institute, and, in 2020, an anonymous donor pledged $252 million to help fund a new center for computing and data science.

    Since 2000, Berkeley alumni and faculty have received 40 Nobel Prizes, behind only Harvard and Massachusetts Institute of Technology among US universities; five Turing Awards, behind only MIT and Stanford University; and five Fields Medals, second only to Princeton University. According to PitchBook, Berkeley ranks second, just behind Stanford University, in producing VC-backed entrepreneurs.

    Bringing Science Solutions to the World

    In the world of science, The Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with “excellence.” Thirteen Nobel prizes are associated with Berkeley Lab. Seventy Lab scientists are members of the The National Academy of Sciences, one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation’s highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the The National Academy of Engineering, and three of our scientists have been elected into The Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world.

    Berkeley Lab is a member of the national laboratory system supported by The DOE through its Office of Science. It is managed by the University of California and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 202-acre site in the hills above The University of California-Berkeley campus that offers spectacular views of the San Francisco Bay, Berkeley Lab employs approximately 3,232 scientists, engineers and support staff. The Lab’s total costs for FY 2014 were $785 million. A recent study estimates the Laboratory’s overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars.

    Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a University of California-Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence’s belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.

    History

    1931–1941

    The laboratory was founded on August 26, 1931, by Ernest Lawrence, as the Radiation Laboratory of the University of California-Berkeley, associated with the Physics Department. It centered physics research around his new instrument, the cyclotron, a type of particle accelerator for which he was awarded the Nobel Prize in Physics in 1939.

    Throughout the 1930s, Lawrence pushed to create larger and larger machines for physics research, courting private philanthropists for funding. He was the first to develop a large team to build big projects to make discoveries in basic research. Eventually these machines grew too large to be held on the university grounds, and in 1940 the lab moved to its current site atop the hill above campus. Part of the team put together during this period includes two other young scientists who went on to establish large laboratories; J. Robert Oppenheimer founded The DOE’s Los Alamos Laboratory, and Robert Wilson founded The DOE’s Fermi National Accelerator Laboratory.

    1942–1950

    Leslie Groves visited Lawrence’s Radiation Laboratory in late 1942 as he was organizing the Manhattan Project, meeting J. Robert Oppenheimer for the first time. Oppenheimer was tasked with organizing the nuclear bomb development effort and founded today’s Los Alamos National Laboratory to help keep the work secret. At the RadLab, Lawrence and his colleagues developed the technique of electromagnetic enrichment of uranium using their experience with cyclotrons. The “calutrons” (named after the University) became the basic unit of the massive Y-12 facility in Oak Ridge, Tennessee. Lawrence’s lab helped contribute to what have been judged to be the three most valuable technology developments of the war (the atomic bomb, proximity fuse, and radar). The cyclotron, whose construction was stalled during the war, was finished in November 1946. The Manhattan Project shut down two months later.

    1951–2018

    After the war, the Radiation Laboratory became one of the first laboratories to be incorporated into the Atomic Energy Commission (AEC) (now The Department of Energy . The most highly classified work remained at Los Alamos, but the RadLab remained involved. Edward Teller suggested setting up a second lab similar to Los Alamos to compete with their designs. This led to the creation of an offshoot of the RadLab (now The DOE’s Lawrence Livermore National Laboratory) in 1952. Some of the RadLab’s work was transferred to the new lab, but some classified research continued at Berkeley Lab until the 1970s, when it became a laboratory dedicated only to unclassified scientific research.

    Shortly after the death of Lawrence in August 1958, the UC Radiation Laboratory (both branches) was renamed the Lawrence Radiation Laboratory. The Berkeley location became the Lawrence Berkeley Laboratory in 1971, although many continued to call it the RadLab. Gradually, another shortened form came into common usage, LBNL. Its formal name was amended to Ernest Orlando Lawrence Berkeley National Laboratory in 1995, when “National” was added to the names of all DOE labs. “Ernest Orlando” was later dropped to shorten the name. Today, the lab is commonly referred to as “Berkeley Lab”.

    The Alvarez Physics Memos are a set of informal working papers of the large group of physicists, engineers, computer programmers, and technicians led by Luis W. Alvarez from the early 1950s until his death in 1988. Over 1700 memos are available on-line, hosted by the Laboratory.

    The lab remains owned by the Department of Energy , with management from the University of California. Companies such as Intel were funding the lab’s research into computing chips.

    Science mission

    From the 1950s through the present, Berkeley Lab has maintained its status as a major international center for physics research, and has also diversified its research program into almost every realm of scientific investigation. Its mission is to solve the most pressing and profound scientific problems facing humanity, conduct basic research for a secure energy future, understand living systems to improve the environment, health, and energy supply, understand matter and energy in the universe, build and safely operate leading scientific facilities for the nation, and train the next generation of scientists and engineers.

    The Laboratory’s 20 scientific divisions are organized within six areas of research: Computing Sciences; Physical Sciences; Earth and Environmental Sciences; Biosciences; Energy Sciences; and Energy Technologies. Berkeley Lab has six main science thrusts: advancing integrated fundamental energy science; integrative biological and environmental system science; advanced computing for science impact; discovering the fundamental properties of matter and energy; accelerators for the future; and developing energy technology innovations for a sustainable future. It was Lawrence’s belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab tradition that continues today.

    Berkeley Lab operates five major National User Facilities for the DOE Office of Science:

    The Advanced Light Source (ALS) is a synchrotron light source with 41 beam lines providing ultraviolet, soft x-ray, and hard x-ray light to scientific experiments.

    The DOE’s Lawrence Berkeley National Laboratory Advanced Light Source.
    The ALS is one of the world’s brightest sources of soft x-rays, which are used to characterize the electronic structure of matter and to reveal microscopic structures with elemental and chemical specificity. About 2,500 scientist-users carry out research at ALS every year. Berkeley Lab is proposing an upgrade of ALS which would increase the coherent flux of soft x-rays by two-three orders of magnitude.

    Berkeley Lab Laser Accelerator (BELLA) Center

    The DOE Joint Genome Institute supports genomic research in support of the DOE missions in alternative energy, global carbon cycling, and environmental management. The JGI’s partner laboratories are Berkeley Lab, DOE’s Lawrence Livermore National Laboratory, DOE’s Oak Ridge National Laboratory (ORNL), DOE’s Pacific Northwest National Laboratory (PNNL), and the HudsonAlpha Institute for Biotechnology . The JGI’s central role is the development of a diversity of large-scale experimental and computational capabilities to link sequence to biological insights relevant to energy and environmental research. Approximately 1,200 scientist-users take advantage of JGI’s capabilities for their research every year.

    LBNL Molecular Foundry

    The LBNL Molecular Foundry is a multidisciplinary nanoscience research facility. Its seven research facilities focus on Imaging and Manipulation of Nanostructures; Nanofabrication; Theory of Nanostructured Materials; Inorganic Nanostructures; Biological Nanostructures; Organic and Macromolecular Synthesis; and Electron Microscopy. Approximately 700 scientist-users make use of these facilities in their research every year.

    The DOE’s NERSC National Energy Research Scientific Computing Center is the scientific computing facility that provides large-scale computing for the DOE’s unclassified research programs. Its current systems provide over 3 billion computational hours annually. NERSC supports 6,000 scientific users from universities, national laboratories, and industry.

    Environmental science student Spencer Toth looks to make new discoveries with bacteriophages.

    University of Delaware undergraduate student Spencer Toth was always interested in the environment and biology, so when she arrived at UD and realized that she could combine both of her passions by double majoring in biology and environmental science, it was a no-brainer.

    Now, having been named the first paid intern through the Environmental Science Program (ENSC), Toth will get the opportunity to work with Eric Wommack, professor of environmental microbiology and associate vice president of the UD Research Office, and Emily Morgese, a microbiology master’s student, in the Viral Informatics and Ecology Lab researching environmental microbiology to try to help aid our understanding of the environment and its ecosystems.

    Toth, who is also in the UD Honors College and in the World Scholars Program, said she worked as an environmental engineering intern in the past, exploring methods of incorporating microplastics into concrete, which was a great introduction into the world of research.

    “It was my first real research experience and it gave me exposure to the field of environmental sustainability and helped me realize that I wanted to focus more on the biological processes of our environment,” Toth said.

    With the help of Pinki Mondal, assistant professor in the Department of Geography and Spatial Sciences and the ENSC program director, Toth applied for and was named the first recipient of the ENSC internship.

    Mondal explained that she wanted to start a paid research internship where ENSC students could work on anything related to the environment, with faculty members from across the university throughout the academic year.

    “Spencer has been very active in finding interdisciplinary research opportunities in different departments at a very early career stage, and she submitted a compelling proposal for the first ENSC internship opportunity,” Mondal said. “I was thrilled to support her proposed research in Viral Ecology and Informatics for this spring/summer. I am grateful for the generous gifts made by alumni, friends and families who made it possible to support these paid research internships.”

    Working in the Viral Informatics and Ecology Lab, Toth will focus on bacteriophages, or bacteria viruses, that attack specific nitrogen-fixing bacteria and learn more about the phenome to genome relationship of these viruses.

    Leguminous plants form mutualistic-symbiotic relationships with bacteria that are beneficial to both the plant and the bacteria. The bacteria are able to provide fixed nitrogen from the atmosphere to the plants in exchange for beneficial byproducts produced by the plant during photosynthesis.

    However, there have been strains of Bradyrhizobium, a nitrogen fixing bacteria, that have been shown to not provide efficient amounts of nitrogen to the plant.

    “So, in a way, it’s almost acting in a parasitic manner,” Toth said. “It’s taking more of the byproducts and not providing the plant with the necessary nitrogen that it needs.”

    For this specific project, Toth will focus on the bacteriophages that attack Bradyrhizobium and learn more about the fundamental behavior of these viruses. Down the line, the hope is to possibly use the viruses in a form of phage-therapy in order to attack these specific cheater bacteria strains.

    The current research involves growing the bacteria, isolating the phage, extracting the DNA, getting the DNA sequences and performing bioinformatics.

    So far, Toth said the project has involved a lot of computational analysis and analyzing those DNA sequences, which has provided her a mix of both in-person culturing and allowed her vital lab experience. She has also been able to do a lot of the necessary bioinformatics work and learn skills that are applicable to various fields.

    The project could also have long-term implications, as in order to even reach the point of phage therapy, researchers first have to understand the fundamentals of how these viruses interact.

    “Being able to contribute to the explorative and the forefront of science in this way was very exciting to me,” Toth said. “There was a period last semester where I wasn’t even sure if I wanted to do research and when I learned more about environmental microbiology, it changed everything.”

    This excitement mostly stems from the fact that a lot of microbiology research is cutting-edge and involves new discoveries.

    “With microbiology, there is a lot that we’re still discovering,” Toth said. “So for me, microbiology was the answer for a specific research-field that makes me feel like I’m doing something significant because it’s contributing to finding new information that we still have yet to know.”

    Toth also said that for any undergraduates interested in research, an important lesson she has learned has been to reach out to faculty across the university.

    “One thing I’ve learned through this whole experience is the importance of networking,” she said. “This all started with emailing and talking with people whose research interested me. Especially for undergraduates who are looking to do research, it just starts with expressing your interests and reaching out to professors. That’s one of the biggest things that has helped me get where I am today, by meeting passionate people who are excited about their work.”

    U Delaware campus

    The University of Delaware is a public land-grant research university located in Newark, Delaware. University of Delaware (US) is the largest university in Delaware. It offers three associate’s programs, 148 bachelor’s programs, 121 master’s programs (with 13 joint degrees), and 55 doctoral programs across its eight colleges. The main campus is in Newark, with satellite campuses in Dover, the Wilmington area, Lewes, and Georgetown. It is considered a large institution with approximately 18,200 undergraduate and 4,200 graduate students. It is a privately governed university which receives public funding for being a land-grant, sea-grant, and space-grant state-supported research institution.

    The University of Delaware is classified among “R1: Doctoral Universities – Very high research activity”. According to The National Science Foundation, UD spent $186 million on research and development in 2018, ranking it 119th in the nation. It is recognized with the Community Engagement Classification by the Carnegie Foundation for the Advancement of Teaching.

    The University of Delaware is one of only four schools in North America with a major in art conservation. In 1923, it was the first American university to offer a study-abroad program.

    The University of Delaware traces its origins to a “Free School,” founded in New London, Pennsylvania in 1743. The school moved to Newark, Delaware by 1765, becoming the Newark Academy. The academy trustees secured a charter for Newark College in 1833 and the academy became part of the college, which changed its name to Delaware College in 1843. While it is not considered one of the colonial colleges because it was not a chartered institution of higher education during the colonial era, its original class of ten students included George Read, Thomas McKean, and James Smith, all three of whom went on to sign the Declaration of Independence. Read also later signed the United States Constitution.

    Science, Technology and Advanced Research (STAR) Campus

    On October 23, 2009, The University of Delaware signed an agreement with Chrysler to purchase a shuttered vehicle assembly plant adjacent to the university for $24.25 million as part of Chrysler’s bankruptcy restructuring plan. The university has developed the 272-acre (1.10 km^2) site into the Science, Technology and Advanced Research (STAR) Campus. The site is the new home of University of Delaware (US)’s College of Health Sciences, which includes teaching and research laboratories and several public health clinics. The STAR Campus also includes research facilities for University of Delaware (US)’s vehicle-to-grid technology, as well as Delaware Technology Park, SevOne, CareNow, Independent Prosthetics and Orthotics, and the East Coast headquarters of Bloom Energy. In 2020 [needs an update], University of Delaware expects to open the Ammon Pinozzotto Biopharmaceutical Innovation Center, which will become the new home of the UD-led National Institute for Innovation in Manufacturing Biopharmaceuticals. Also, Chemours recently opened its global research and development facility, known as the Discovery Hub, on the STAR Campus in 2020. The new Newark Regional Transportation Center on the STAR Campus will serve passengers of Amtrak and regional rail.

    Academics

    The university is organized into nine colleges:

    Alfred Lerner College of Business and Economics
    College of Agriculture and Natural Resources
    College of Arts and Sciences
    College of Earth, Ocean and Environment
    College of Education and Human Development
    College of Engineering
    College of Health Sciences
    Graduate College
    Honors College

    There are also five schools:

    Joseph R. Biden, Jr. School of Public Policy and Administration (part of the College of Arts & Sciences)
    School of Education (part of the College of Education & Human Development)
    School of Marine Science and Policy (part of the College of Earth, Ocean and Environment)
    School of Nursing (part of the College of Health Sciences)
    School of Music (part of the College of Arts & Sciences)

    Martin Stute and Grace Brown are studying the process of turning CO2 to stone.

    Climate science was not on Grace Brown’s mind when she decided to attend Barnard. Brown, who grew up in Westfield, New Jersey, had always gravitated toward outdoor conservation activities. When she came to Barnard, she was considering majoring in political science. But her environmental studies courses and Barnard’s access to cutting-edge science at the Columbia Climate School drew Brown into a new area of exploration.

    Last spring, Brown, who is now a senior and an environmental studies major, was looking for a project for her senior thesis. She asked for suggestions from environmental sciences professor Martin Stute, a leader in the area of hydrology and groundwater studies. As an adjunct senior research scientist at the Climate School’s Lamont-Doherty Earth Observatory, Stute has also been advancing a pivotal climate science research and development area: carbon capture and storage.

    Stute needed help with an ongoing, high-profile project in Oman. Brown would only need to go as far as Palisades, New York, and Columbia’s Lamont-Doherty Earth Observatory to be part of groundbreaking science. Once an elusive goal, carbon dioxide removal (CDR) — using science to remove CO2 from the air and then stow it safely away — is now considered an important, emerging technology, critical for helping reduce greenhouse gas emissions and, in this way, is helping to solve the greater climate change crisis.

    In the Q&A below, Stute and Brown talk about the Oman project and the promise of carbon capture.
    _______________________________________________________________________________

    What’s involved with carbon capture and sequestration?

    MS: In order to limit the effects of climate change, we need to not only cut back on our greenhouse gas emissions (mostly CO2 and methane) but also take some of these gases that we have put into the atmosphere back out. Carbon (in the form of CO2 and methane) can be captured at the source — for example, at a power plant — or directly from the air and then stored in plants, industrial materials, or in subsurface pores and cavities. I am working on one of the safest ways to store CO2 in the subsurface using a process called ‘carbon mineralization,’ in which CO2 is dissolved in water, pumped into reactive rocks such as basalts, where the CO2 is then converted to solid carbonate minerals (similar to limestone). I was part of an international team that demonstrated this process in a field application in Iceland.

    What’s happening in Oman?

    MS: This project is part of a large international research program that explores the geochemistry and microbiology of an ancient uplifted seafloor in the desert of Oman. Besides being used to study basic biogeochemical processes, this formation could also store vast quantities of CO2, similar to the basalts in Iceland. A key question of the study is how fast water circulates in this formation. Our study — funded by the US National Science Foundation in collaboration with California State University-Sacramento, and the Oman Drilling Project — uses substances naturally occurring in groundwater at very low concentrations (so-called ‘tracers’ such as radiocarbon, tritium, and noble gases) to determine how long the water has been underground and how fast it moves. This information is crucial for determining chemical reaction rates and how this formation could be used for CO2 storage.

    How far are we from realizing the goal of removing carbon dioxide from the air and storing it away safely?

    MS: The capture and storage of large CO2 sources are well understood and economically feasible. Free-air capture is still expensive; large-scale demonstrations must be developed and deployed. However, many commercial carbon capture and storage plants are now operating worldwide. In fact, a startup company called 44.01, which received last year’s Earthshot Prize, has begun experimental CO2 injections in Oman. All this is not to say that carbon capture and storage is the silver bullet that will solve our greenhouse gas problem. It is just one approach that needs to be taken if we want to limit the worst effects of climate change. We still need to move to renewable energy sources as quickly as possible and transition to a sustainable economy.

    What surprised you most about the Oman project and your work in support of it?

    GB: I was surprised by the amount of technical, hands-on work I’ve gotten in methods development and instrumentation. Last summer, we spent a lot of time in the lab modifying our different analytical instruments to enable us to develop techniques specific to measuring samples and collecting data for the project. While this kind of method development is a large part of the research process, I was surprised to get this kind of behind-the-scenes look at the more technical aspects of scientific instrumentation. Something else that surprised me, I hadn’t realized how students can get involved with and contribute directly to groundbreaking projects. I’ve found that through the senior thesis and other opportunities available to us, students are really able to make an impact and contribute to extremely relevant research. It’s been very exciting and rewarding.

    Does being so involved with emerging research make you more hopeful about the future in light of what we know about the threat of climate change?

    GB: Being involved with emerging research definitely makes me more hopeful about the future. I think a major factor contributing to pessimism about climate change is the feeling that there’s nothing we can do about it, so I feel much more optimistic when I can take action. Spending time at places like the Lamont-Doherty Earth Observatory, I can’t help but feel hopeful when surrounded by so many scientists at the top of their field working very hard to understand the Earth and its changing climate better.

    The Lamont–Doherty Earth Observatory is the scientific research center of the Columbia Climate School, and a unit of The Earth Institute at Columbia University.

    It focuses on climate and earth sciences and is located on a 189-acre (64 ha) campus in Palisades, New York, 18 miles (29 km) north of Manhattan on the Hudson River.

    The Lamont–Doherty Earth Observatory was established in 1949 as the Lamont Geological Observatory on the weekend estate of Thomas W. and Florence Haskell Corliss Lamont, which was donated to the university for that purpose. The Observatory’s founder and first director was Maurice “Doc” Ewing, a seismologist who is credited with advancing efforts to study the solid Earth, particularly in areas related to using sound waves to image rock and sediments beneath the ocean floor. He was also the first to collect sediment core samples from the bottom of the ocean, a common practice today that helps scientists study changes in the planet’s climate and the ocean’s thermohaline circulation.

    In 1969, the Observatory was renamed Lamont–Doherty in honor of a major gift from the Henry L. and Grace Doherty Charitable Foundation; in 1993, it was renamed the Lamont–Doherty Earth Observatory in recognition of its expertise in the broad range of Earth sciences. Lamont–Doherty Earth Observatory is Columbia University’s Earth sciences research center and is a core component of the Earth Institute, a collection of academic and research units within the university that together address complex environmental issues facing the planet and its inhabitants, with particular focus on advancing scientific research to support sustainable development and the needs of the world’s poor.

    The Lamont–Doherty Earth Observatory at Columbia University is one of the world’s leading research centers developing fundamental knowledge about the origin, evolution and future of the natural world. More than 300 research scientists and students study the planet from its deepest interior to the outer reaches of its atmosphere, on every continent and in every ocean. From global climate change to earthquakes, volcanoes, nonrenewable resources, environmental hazards and beyond, Observatory scientists provide a rational basis for the difficult choices facing humankind in the planet’s stewardship.

    To support its research and the work of the broader scientific community, Lamont–Doherty operates the 235-foot (72 m) research vessel, the R/V Marcus Langseth, which is equipped to undertake a wide range of geological, seismological, oceanographic and biological studies.

    Lamont–Doherty also houses the world’s largest collection of deep-sea and ocean-sediment cores as well as many specialized research laboratories.

    Columbia U Campus
    Columbia University was founded in 1754 as King’s College by royal charter of King George II of England. It is the oldest institution of higher learning in the state of New York and the fifth oldest in the United States.

    University Mission Statement

    Columbia University is one of the world’s most important centers of research and at the same time a distinctive and distinguished learning environment for undergraduates and graduate students in many scholarly and professional fields. The University recognizes the importance of its location in New York City and seeks to link its research and teaching to the vast resources of a great metropolis. It seeks to attract a diverse and international faculty and student body, to support research and teaching on global issues, and to create academic relationships with many countries and regions. It expects all areas of the University to advance knowledge and learning at the highest level and to convey the products of its efforts to the world.

    Columbia University is a private Ivy League research university in New York City. Established in 1754 on the grounds of Trinity Church in Manhattan Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States. It is one of nine colonial colleges founded prior to the Declaration of Independence, seven of which belong to the Ivy League. Columbia is ranked among the top universities in the world by major education publications.

    Columbia was established as King’s College by royal charter from King George II of Great Britain in reaction to the founding of Princeton College. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University.

    Columbia scientists and scholars have played an important role in scientific breakthroughs including brain-computer interface; the laser and maser; nuclear magnetic resonance; the first nuclear pile; the first nuclear fission reaction in the Americas; the first evidence for plate tectonics and continental drift; and much of the initial research and planning for the Manhattan Project during World War II. Columbia is organized into twenty schools, including four undergraduate schools and 15 graduate schools. The university’s research efforts include the Lamont–Doherty Earth Observatory, the Goddard Institute for Space Studies, and accelerator laboratories with major technology firms such as IBM. Columbia is a founding member of the Association of American Universities and was the first school in the United States to grant the M.D. degree. With over 14 million volumes, Columbia University Library is the third largest private research library in the United States.

    The university’s endowment stands at $11.26 billion in 2020, among the largest of any academic institution. As of October 2020, Columbia’s alumni, faculty, and staff have included: five Founding Fathers of the United States—among them a co-author of the United States Constitution and a co-author of the Declaration of Independence; three U.S. presidents; 29 foreign heads of state; ten justices of the United States Supreme Court, one of whom currently serves; 96 Nobel laureates; five Fields Medalists; 122 National Academy of Sciences members; 53 living billionaires; eleven Olympic medalists; 33 Academy Award winners; and 125 Pulitzer Prize recipients.

    Richard Losick highlights flawed, human side of science in his MSI Distinguished Achievement Award lecture.

    Harvard microbiologist Richard Losick is still teaching at age 80 and did so Saturday, telling an audience of well over 100 at Harvard’s Northwest Building the story of DNA’s discovery — the real story — one of insights ahead of their time, of recognition denied and buried by incorrect dogma, and of credit eventually going to another.

    The tale was compelling enough itself, bearing lessons not just about the science of life that Losick has loved and passed on to others for decades, but also about the unpredictability of science — like any enterprise — once humans get involved in it.

    The bonus for the crowd, though, was the revered scientist telling it. The Maria Moors Cabot Professor of Biology has been at Harvard for 55 years, arriving as a junior fellow in 1968. On Saturday the microbial community came together for the Harvard Microbial Sciences Initiative’s 20th annual Microbial Sciences Symposium, a daylong affair that was capped by the presentation to Losick of the first MSI Distinguished Achievement Award.

    Using the bacterium Bacillus subtilis as a model, Losick has investigated some of life’s most basic processes, from DNA expression to how cells communicate, from protein activity to bacterial colonies and biofilms. In addition to his scientific work, Losick is known for his dedication to undergraduate teaching. As a Howard Hughes Medical Institute Professor, Losick is actively engaged in reforming undergraduate science education, making it more interdisciplinary and hands-on.

    Niels Bradshaw, assistant professor of biochemistry at Brandeis University, was a postdoc with Losick, and called him “my science hero, my mentor, my friend, and now my collaborator.”

    “Rich has been many of those things to many people in this room, some much longer than me,” Bradshaw said. “He’s also had a singularly important impact on life sciences research for longer than I’ve been alive.”

    The event itself brought almost 300 students, faculty, and researchers from Harvard and beyond to the Northwest Building for talks about everything from using artificial intelligence to fight pathogens to bacterial metabolism and physiology to host and predator impacts on pathogens to evolutionary and historical insights into microbiology.

    The program also included several “Science Art Features” that highlighted the beauty of the microbial world, and a talk and demonstration on chocolate fermentation.

    “In terms of audience, my work is aimed at everyone,” said artist Rogan Brown via video, referring to his elaborate paper sculptures of microbial colonies. “People can respond to it on a purely aesthetic level, or they can delve deeper into the ideas behind the sculpture. Also, it is my goal to show that beauty can be found in the most unlikely places, and it is both art and science that shine a light into those places.”

    Peter Girguis, professor of organismic and evolutionary biology and one of the event’s organizers, said part of its aim was to communicate science in as many ways as possible, whether through the feast for the eyes presented by visual artists, for the mind through scientific talks, or directly to the stomach with a dose of chocolate.

    In his award address, Losick told the story of a team, led by Oswald Avery, that in 1943 purified what they believed was the “transforming principle” that carried the information that allowed cells of one type to change into another.

    He outlined Avery’s work, carried out at the Rockefeller Institute in New York City, which involved two different strains of the bacteria that causes pneumonia. One was virulent and formed smooth-looking colonies on plates of nutrient agar. The second, nonvirulent, formed rough-looking colonies.

    By purifying molecules that they believed to be the “transforming principle,” they were able to change batches of nonvirulent into virulent strains. They determined that the “transforming principle” was DNA, a molecule that was already known to science, but whose foundational role in carrying genetic information was not.

    Instead of gaining praise for the work, Avery came under fire. The prevailing hypothesis about how genetic information was carried in the cell was that it was done by proteins, which are more complex molecules than DNA.

    One who held that theory was Alfred Mirsky, also at the Rockefeller Institute. Mirsky insisted that Avery’s samples were contaminated with traces of protein that explained their functionality. Despite efforts by Avery’s team, which included Colin MacLeod and Maclyn McCarty, to produce ever-purer DNA samples, Mirsky kept up the drumbeat for years. Avery, who was nominated for the Nobel Prize several times, wound up seeing the prize go to Alfred Hershey, Max Delbruck, and Salvador Luria for experiments conducted years later that confirmed DNA as the body’s genetic material.

    In explaining how Avery wound up being ignored, Losick attributed part of it to the strength of the prevailing dogma that genetic material had to be a protein, in part because DNA, with just four repeating bases, was thought not to be complex enough.

    He also pointed to Mirsky’s efforts to discredit Avery, aided by Avery’s low-key personality. In addition, he said, the Nobel winners were part of a well-known group of biologists who explored bacterial genetics, called the “Phage Group,” because of their use of bacteriophages, a type of virus that infects bacteria.

    “To me, the Phage Group and nucleic acid biochemists lived in different intellectual worlds. And the discovery of Avery was simply ahead of its time and largely went unappreciated. Nevertheless and looking back, we can say it represents one of the greatest of all discoveries in the biological sciences in the last century,” Losick said. “Today we celebrate the 20th anniversary of Microbial Sciences Initiative. … Let’s also celebrate the 80th anniversary of Oswald Avery’s transformative discovery in 1943 and — if you’ll permit me — of vastly less significance, yours truly is celebrating my 80th year on this planet. I was born the same year as the Avery, McCarty, MacLeod experiment, but to be honest was too young to appreciate it.”

    Harvard University campus

    Harvard University is the oldest institution of higher education in the United States, established in 1636 by vote of the Great and General Court of the Massachusetts Bay Colony. It was named after the College’s first benefactor, the young minister John Harvard of Charlestown, who upon his death in 1638 left his library and half his estate to the institution. A statue of John Harvard stands today in front of University Hall in Harvard Yard, and is perhaps the University’s best-known landmark.

    Harvard University has 12 degree-granting Schools in addition to the Radcliffe Institute for Advanced Study. The University has grown from nine students with a single master to an enrollment of more than 20,000 degree candidates including undergraduate, graduate, and professional students. There are more than 360,000 living alumni in the U.S. and over 190 other countries.

    The Massachusetts colonial legislature, the General Court, authorized Harvard University’s founding. In its early years, Harvard College primarily trained Congregational and Unitarian clergy, although it has never been formally affiliated with any denomination. Its curriculum and student body were gradually secularized during the 18th century, and by the 19th century, Harvard University (US) had emerged as the central cultural establishment among the Boston elite. Following the American Civil War, President Charles William Eliot’s long tenure (1869–1909) transformed the college and affiliated professional schools into a modern research university; Harvard became a founding member of the Association of American Universities in 1900. James B. Conant led the university through the Great Depression and World War II; he liberalized admissions after the war.

    The university is composed of ten academic faculties plus the Radcliffe Institute for Advanced Study. Arts and Sciences offers study in a wide range of academic disciplines for undergraduates and for graduates, while the other faculties offer only graduate degrees, mostly professional. Harvard has three main campuses: the 209-acre (85 ha) Cambridge campus centered on Harvard Yard; an adjoining campus immediately across the Charles River in the Allston neighborhood of Boston; and the medical campus in Boston’s Longwood Medical Area. Harvard University’s endowment is valued at $41.9 billion, making it the largest of any academic institution. Endowment income helps enable the undergraduate college to admit students regardless of financial need and provide generous financial aid with no loans The Harvard Library is the world’s largest academic library system, comprising 79 individual libraries holding about 20.4 million items.

    Harvard University has more alumni, faculty, and researchers who have won Nobel Prizes (161) and Fields Medals (18) than any other university in the world and more alumni who have been members of the U.S. Congress, MacArthur Fellows, Rhodes Scholars (375), and Marshall Scholars (255) than any other university in the United States. Its alumni also include eight U.S. presidents and 188 living billionaires, the most of any university. Fourteen Turing Award laureates have been Harvard affiliates. Students and alumni have also won 10 Academy Awards, 48 Pulitzer Prizes, and 108 Olympic medals (46 gold), and they have founded many notable companies.

    Colonial

    Harvard University was established in 1636 by vote of the Great and General Court of the Massachusetts Bay Colony. In 1638, it acquired British North America’s first known printing press. In 1639, it was named Harvard College after deceased clergyman John Harvard, an alumnus of the University of Cambridge(UK) who had left the school £779 and his library of some 400 volumes. The charter creating the Harvard Corporation was granted in 1650.

    A 1643 publication gave the school’s purpose as “to advance learning and perpetuate it to posterity, dreading to leave an illiterate ministry to the churches when our present ministers shall lie in the dust.” It trained many Puritan ministers in its early years and offered a classic curriculum based on the English university model—many leaders in the colony had attended the University of Cambridge—but conformed to the tenets of Puritanism. Harvard University has never affiliated with any particular denomination, though many of its earliest graduates went on to become clergymen in Congregational and Unitarian churches.

    Increase Mather served as president from 1681 to 1701. In 1708, John Leverett became the first president who was not also a clergyman, marking a turning of the college away from Puritanism and toward intellectual independence.

    19th century

    In the 19th century, Enlightenment ideas of reason and free will were widespread among Congregational ministers, putting those ministers and their congregations in tension with more traditionalist, Calvinist parties. When Hollis Professor of Divinity David Tappan died in 1803 and President Joseph Willard died a year later, a struggle broke out over their replacements. Henry Ware was elected to the Hollis chair in 1805, and the liberal Samuel Webber was appointed to the presidency two years later, signaling the shift from the dominance of traditional ideas at Harvard to the dominance of liberal, Arminian ideas.

    Charles William Eliot, president 1869–1909, eliminated the favored position of Christianity from the curriculum while opening it to student self-direction. Though Eliot was the crucial figure in the secularization of American higher education, he was motivated not by a desire to secularize education but by Transcendentalist Unitarian convictions influenced by William Ellery Channing and Ralph Waldo Emerson.

    20th century

    In the 20th century, Harvard University’s reputation grew as a burgeoning endowment and prominent professors expanded the university’s scope. Rapid enrollment growth continued as new graduate schools were begun and the undergraduate college expanded. Radcliffe College, established in 1879 as the female counterpart of Harvard College, became one of the most prominent schools for women in the United States. Harvard University became a founding member of the Association of American Universities in 1900.

    The student body in the early decades of the century was predominantly “old-stock, high-status Protestants, especially Episcopalians, Congregationalists, and Presbyterians.” A 1923 proposal by President A. Lawrence Lowell that Jews be limited to 15% of undergraduates was rejected, but Lowell did ban blacks from freshman dormitories.

    President James B. Conant reinvigorated creative scholarship to guarantee Harvard University’s preeminence among research institutions. He saw higher education as a vehicle of opportunity for the talented rather than an entitlement for the wealthy, so Conant devised programs to identify, recruit, and support talented youth. In 1943, he asked the faculty to make a definitive statement about what general education ought to be, at the secondary as well as at the college level. The resulting Report, published in 1945, was one of the most influential manifestos in 20th century American education.

    Between 1945 and 1960, admissions were opened up to bring in a more diverse group of students. No longer drawing mostly from select New England prep schools, the undergraduate college became accessible to striving middle class students from public schools; many more Jews and Catholics were admitted, but few blacks, Hispanics, or Asians. Throughout the rest of the 20th century, Harvard became more diverse.

    Harvard University’s graduate schools began admitting women in small numbers in the late 19th century. During World War II, students at Radcliffe College (which since 1879 had been paying Harvard University professors to repeat their lectures for women) began attending Harvard University classes alongside men. Women were first admitted to the medical school in 1945. Since 1971, Harvard University has controlled essentially all aspects of undergraduate admission, instruction, and housing for Radcliffe women. In 1999, Radcliffe was formally merged into Harvard University.
