    Every so often, somewhere beneath our feet, rocks rupture, and an earthquake begins. With big enough ruptures, we might feel an earthquake as seismic waves radiate to or along the surface. However, a mere 15% to 20% of the energy needed to break rocks in the first place translates into seismicity, scientists suspect.

    The remaining energy can dissipate as frictional heat, leaving behind melted planes of glassy rock called pseudotachylyte. The leftover energy may also fracture, pulverize, or deform rocks that surround the rupture as it rushes through the crust, said Erik Anderson, a doctoral student at the University of Maine (US). Because these processes occur kilometers below Earth’s surface, scientists cannot directly observe them when modern earthquakes strike. Shear zones millions of years old that now reside at the surface can provide windows into the rocks around ancient ruptures. However, although seismogenically altered rocks remain at depth, heat and pressure can erase clues of past quakes, said Anderson. “We need some other proxy,” he said, “when we’re looking for evidence of earthquakes in the rock record.”

    Micas—sheetlike minerals that can stack together in individual crystals that often provide the sparkle in kitchen countertops—can preserve deformation features that look like microscopic chevrons. On geology’s macroscale, chevrons form in layered strata. In minuscule sheaves of mica, petrologists observe similar pointy folds because the structure of the mica leaves it prone to kinking, rather than buckling or folding, said Frans Aben, a rock physicist at University College London (UK).

    In a new article in Earth and Planetary Science Letters, Anderson and his colleagues argue that these microstructures—called kink bands—often mark bygone earthquake ruptures and might outlast other indicators of seismicity.

    Ancient Kink Bands, Explosive Explanation

    To observe kinked micas, scientists must carefully cut rocks into slivers thinner than the typical width of a human hair and affix each rock slice to a piece of glass. By using high-powered microscopes to examine this rock and glass combination (aptly called a thin section), Anderson and his colleagues compared kink bands from two locations in Maine, both more than 300 million years old. The first location is rife with telltale signs of a dynamically deformed former seismogenic zone, like shattered garnets and pseudotachylyte. The second location exposes rocks that changed slowly, under relatively static conditions.

    Comparing the geometry of the kink bands from these sites, the researchers observed differences in the thicknesses and symmetries of the microstructures. In particular, samples from the dynamically deformed location display thin-sided, asymmetric kinks. The more statically deformed samples showcase equally proportioned points with thicker limbs.

    Kink bands, said Aben, can be added to a growing list of indicators of seismic activity in otherwise cryptic shear zones. The data, he said, “speak for themselves.” Aben was not involved in this study.

    To further cement the link between earthquakes and kink band geometry, Anderson and colleagues analyzed 1960s era studies largely driven by the development of nuclear weapons. During that time, scientists strove to understand how shock waves emanated from sites of sudden, rapid, massive perturbations like those produced at nuclear test sites or meteor impact craters. Micas developed kink bands at such sites, as well as in complementary laboratory experiments, said Anderson, and they mimic the geometric patterns produced by dynamic strain rate events—like earthquakes. “[Kink band] geometry,” Anderson said, “is directly linked to the mode of deformation.”

    Stressing Rocks, Kinking Micas

    In addition to exploring whether kinked mica geometry could fingerprint relics of earthquake ruptures, Anderson and his colleagues estimated the magnitude of localized, transient stress their samples experienced as an earthquake’s rupture front propagated through the rocks, he said. In other words, he asked, might the geometry of kinked micas scale with the magnitude of momentary stress that kinked the micas in the first place?

    By extrapolating data from previously published laboratory experiments, Anderson estimated that pulverizing rocks at the deepest depths at which earthquakes can nucleate requires up to 2 gigapascals of stress. Although stress doesn’t directly correspond to pressure, 2 gigapascals are equivalent to more than 7,200 times the pressure inside a car tire inflated to 40 pounds per square inch. For reference, the unimaginably crushing pressure in the deepest part of the ocean—the Mariana Trench—is only about 400 times the pressure in that same tire.

    By the same conversion, kinking micas requires stresses 8–30 times the water pressure in the deepest ocean. Because Anderson found pulverized garnets proximal to kinked micas at the fault-filled field site, he and his colleagues inferred that the stresses momentarily experienced by these rocks as an earthquake’s rupture tore through the shear zone were about 1 gigapascal, or 9 times the pressure at the Mariana Trench.

    Aben described this transient stress estimate for earthquakes as speculative, but he said the new study’s focus on earthquake-induced deformation fills a gap in research between very slow rock deformation that builds mountains and extremely rapid deformation that occurs during nuclear weapons testing and meteor impacts. And with micas, he said, “once they’re kinked, they will remain kinked,” preserving records of ancient earthquakes in the hearts of mountains.

    Looking like the “Eye of Sauron” from the Lord of the Rings trilogy, an ancient undersea volcano was slowly revealed by multibeam sonar 3,100 meters (10,170 ft) below our vessel, 280 kilometers (174 miles) southeast of Christmas Island.

    This was on day 12 of our voyage of exploration to Australia’s Indian Ocean Territories, aboard CSIRO’s R/V Investigator.

    Previously unknown and unimagined, this volcano emerged from our screens as a giant oval-shaped depression called a caldera, 6.2 km by 4.8 km across. It is surrounded by a 300-m-high rim (resembling Sauron’s eyelids), and has a 300-m-high cone-shaped peak at its center (the ‘pupil’).

    A caldera is formed when a volcano collapses. The molten magma at the base of the volcano shifts upwards, leaving empty chambers. The thin solid crust on the surface of the dome then collapses, creating a large crater-like structure. Often, a small new peak then begins to form in the center as the volcano continues spewing magma.

    One well-known caldera is the one at Krakatoa in Indonesia, which exploded in 1883, killing tens of thousands of people and leaving only bits of the mountain rim visible above the waves. By 1927, a small volcano, Anak Krakatoa (“child of Krakatoa”), had grown in its center.

    In contrast, we may not even be aware of volcanic eruptions when they happen deep under the ocean. One of the few tell-tale signs is the presence of rafts of light pumice stone floating on the sea surface after being blown out of a submarine volcano. Eventually, this pumice stone becomes waterlogged and sinks to the ocean floor.

    Our volcanic ‘eye’ was not alone. Further mapping to the south revealed a smaller sea mountain covered in numerous volcanic cones, and further still to the south was a larger, flat-topped seamount.

    Following our Lord of the Rings theme, we have nicknamed them “Barad-dûr (‘Dark Fortress’)” and “Ered Lithui (‘Ash Mountains’)”, respectively.

    Although author J.R.R. Tolkien’s knowledge of mountain geology wasn’t perfect, our names are wonderfully appropriate given the jagged nature of the first and the pumice-covered surface of the second.

    The Eye of Sauron, Barad-dûr, and Ered Lithui are part of the Karma cluster of seamounts that have been previously estimated by geologists to be more than 100 million years old, and which formed next to an ancient sea ridge from a time when Australia was situated much further south, near Antarctica.

    The flat summit of Ered Lithui was formed by wave erosion when the seamount protruded above the sea surface, before the heavy seamount slowly sank back down into the soft ocean seafloor. The summit of Ered Lithui is now 2.6 km below sea level.

    5
    But here is the geological conundrum. Our caldera looks surprisingly fresh for a structure that should be more than 100 million years old. Ered Lithui has almost 100 m of sand and mud layers draped over its summit, formed by sinking dead organisms over millions of years.

    This sedimentation rate would have partially smothered the caldera. Instead it is possible that volcanoes have continued to sprout or new ones formed long after the original foundation. Our restless Earth is never still.

    But life adapts to these geological changes, and Ered Lithui is now covered in seafloor animals. Brittle-stars, sea-stars, crabs, and worms burrow into or skate over the sandy surface. Erect black corals, fan-corals, sea-whips, sponges, and barnacles grow on exposed rocks. Gelatinous cusk-eels prowl around rock gullies and boulders. Batfish lie in wait for unsuspecting prey.

    Our mission is to map the seafloor and survey sea life from these ancient and secluded seascapes. The Australian government recently announced plans to create two massive marine parks across the regions. Our expedition will supply scientific data that will help Parks Australia to manage these areas into the future.

    Scientists from museums, universities, CSIRO, and Bush Blitz around Australia are participating in the voyage. We are close to completing part one of our journey to the Christmas Island region. Part two of our journey to the Cocos (Keeling) Island region will be scheduled in the next year or so.

    No doubt many animals that we find here will be new to science and our first records of their existence will be from this region. We expect many more surprising discoveries.

    CSIRO -Commonwealth Scientific and Industrial Research Organisation (AU) , is Australia’s national science agency and one of the largest and most diverse research agencies in the world.

    CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people.

    Federally funded scientific research began in Australia 104 years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949 further legislated changes included renaming the organisation as CSIRO.

    Notable developments by CSIRO have included the invention of atomic absorption spectroscopy; essential components of Wi-Fi technology; development of the first commercially successful polymer banknote; the invention of the insect repellent in Aerogard and the introduction of a series of biological controls into Australia, such as the introduction of myxomatosis and rabbit calicivirus for the control of rabbit populations.

    One of Earth’s greatest mysteries is how it transformed itself ever so gradually from a barren ball of rock into a launching pad for life.

    Earth scientists have spent decades piecing together the relevant clues — identifying and studying the planet’s complex interplay of geological processes, atmospheric dynamics, and chemical cycles. In particular, scientists have studied the roles played by carbon and silicon in stabilizing Earth’s climate over a vast stretch of time.

    Now a Yale-led study in the journal Nature provides an unprecedented look at this 3-billion-year-old story, told in ancient sediments from around the world.

    “We wanted to advance our understanding of what processes have regulated Earth’s climate over geologic time scales,” said Noah Planavsky, an associate professor of Earth and planetary sciences in Yale’s Faculty of Arts and Sciences and co-corresponding author of the new study with Yale graduate student Boriana Kalderon-Asael and University College London (UK) researcher Philip Pogge von Strandmann.

    “How the Earth’s climate has remained stable for the majority of the last 3 billion years is one of the most fundamental questions one can ask about how the Earth works,” Planavsky said.

    At the root of Earth’s climate life story is its ability to remove carbon dioxide from the atmosphere and store it in rocks and sediments. We have plants to thank for that, the researchers said.

    The emergence of plants on land and in the ocean led to gradual — but major — changes in how rocks and sediments weathered. These changes in weathering opened the door for sequestering carbon into the Earth itself.

    “The result was a substantial decrease in carbon dioxide levels, which kept pace with the increasing luminosity of the sun as it aged, helping to ensure that the Earth remained persistently habitable to both simple and complex life forms,” Planavsky said.

    Kalderon-Asael and Planavsky led an international team of researchers that gathered more than 600 sediment samples at roughly 100 sites worldwide. The researchers studied geochemical data found in lithium isotopes in the samples — a methodology used in other studies over the past decade to look at specific points in Earth’s recent and distant past.

    The new study encompasses the entirety of Earth’s history allowing researchers to document the evolution of how Earth regulated its climate.

    “It gives us the whole picture,” said Kalderon-Asael, the study’s first author. “This began as a one-year project to look at a couple of sites. As we started to see the data come in, we added more collaborators and more samples until we were able to look at all of Earth’s history.”

    In addition to the history lesson, the study offers a long-term perspective on the rapid changes in global climate today.

    “Through all of the massive changes Earth has undergone — in the biosphere and in the amount of solar radiation it receives — it has remained habitable by making adjustments on extremely long time-scales,” Planavsky said. “It highlights how totally unprecedented the current shifts are in the carbon cycle.”

    The research was funded, in part, by the Alternative Earths NASA Astrobiology Institute, the Packard Foundation, and the Yale Institute for Biospheric Studies.

    About Yale University (US)

    Yale University (US) is a private Ivy League research university in New Haven, Connecticut. Founded in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and one of the nine Colonial Colleges chartered before the American Revolution. Collegiate School was renamed Yale College in 1718 to honor the school’s largest benefactor, Elihu Yale.

    Yale University (US) comprises three major academic components: Yale College (the undergraduate program); the Graduate School of Arts and Sciences; and the professional schools. In addition, Yale encompasses a wide array of centers and programs, libraries, museums, and administrative support offices. Approximately 11,250 students attend Yale.

    Chartered by Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers. It moved to New Haven in 1716 and shortly after was renamed Yale College in recognition of a gift from East India Company governor Elihu Yale. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale’s faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research.

    Yale is organized into fourteen constituent schools: the original undergraduate college; the Yale Graduate School of Arts and Sciences; and twelve professional schools. While the university is governed by the Yale Corporation, each school’s faculty oversees its curriculum and degree programs. In addition to a central campus in downtown New Haven, the university owns athletic facilities in western New Haven, a campus in West Haven, Connecticut, and forests and nature preserves throughout New England. As of September 2019, the university’s assets include an endowment valued at $30.3 billion, the second largest endowment of any educational institution in North America. The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States. Students compete in intercollegiate sports as the Yale Bulldogs in the NCAA Division I – Ivy League.

    As of October 2020, 65 Nobel laureates, five Fields Medalists and three Turing award winners have been affiliated with Yale University. In addition, Yale has graduated many notable alumni, including five U.S. Presidents; 19 U.S. Supreme Court Justices; 31 living billionaires; and many heads of state. Hundreds of members of Congress and many U.S. diplomats; 78 MacArthur Fellows; 252 Rhodes Scholars; 123 Marshall Scholars; and nine Mitchell Scholars have been affiliated with the university.

    Yale traces its beginnings to “An Act for Liberty to Erect a Collegiate School”, a would-be charter passed during a meeting in New Haven by the General Court of the Colony of Connecticut on October 9, 1701. The Act was an effort to create an institution to train ministers and lay leadership for Connecticut. Soon after, a group of ten Congregational ministers, Samuel Andrew; Thomas Buckingham; Israel Chauncy; Samuel Mather (nephew of Increase Mather); Rev. James Noyes II (son of James Noyes); James Pierpont; Abraham Pierson; Noadiah Russell; Joseph Webb; and Timothy Woodbridge, all alumni of Harvard University(US), met in the study of Reverend Samuel Russell located in Branford, Connecticut to donate their books to form the school’s library. The group, led by James Pierpont, is now known as “The Founders”.

    Originally known as the “Collegiate School”, the institution opened in the home of its first rector, Abraham Pierson, who is today considered the first president of Yale. Pierson lived in Killingworth (now Clinton). The school moved to Saybrook and then Wethersfield. In 1716, it moved to New Haven, Connecticut.

    Meanwhile, there was a rift forming at Harvard between its sixth president, Increase Mather, and the rest of the Harvard clergy, whom Mather viewed as increasingly liberal, ecclesiastically lax, and overly broad in Church polity. The feud caused the Mathers to champion the success of the Collegiate School in the hope that it would maintain the Puritan religious orthodoxy in a way that Harvard had not.

    Naming and development

    1
    Coat of arms of the family of Elihu Yale, after whom the university was named in 1718

    In 1718, at the behest of either Rector Samuel Andrew or the colony’s Governor Gurdon Saltonstall, Cotton Mather contacted the successful Boston born businessman Elihu Yale to ask him for financial help in constructing a new building for the college. Through the persuasion of Jeremiah Dummer, Elihu “Eli” Yale, who had made a fortune in Madras while working for the East India Company overseeing its slave trading activities, donated nine bales of goods, which were sold for more than £560, a substantial sum of money at the time. Cotton Mather suggested that the school change its name to “Yale College.” The name Yale is the Anglicized spelling of the Iâl, which the family estate at Plas yn Iâl, near the village of Llandegla, was called.

    Meanwhile, a Harvard graduate working in England convinced some 180 prominent intellectuals to donate books to Yale. The 1714 shipment of 500 books represented the best of modern English literature; science; philosophy; and theology at the time. It had a profound effect on intellectuals at Yale. Undergraduate Jonathan Edwards discovered John Locke’s works and developed his original theology known as the “new divinity.” In 1722 the Rector and six of his friends, who had a study group to discuss the new ideas, announced that they had given up Calvinism, become Arminians, and joined the Church of England. They were ordained in England and returned to the colonies as missionaries for the Anglican faith. Thomas Clapp became president in 1745 and while he attempted to return the college to Calvinist orthodoxy, he did not close the library. Other students found Deist books in the library.

    Curriculum

    Yale College undergraduates follow a liberal arts curriculum with departmental majors and is organized into a social system of residential colleges.

    Yale was swept up by the great intellectual movements of the period—the Great Awakening and the Enlightenment—due to the religious and scientific interests of presidents Thomas Clap and Ezra Stiles. They were both instrumental in developing the scientific curriculum at Yale while dealing with wars, student tumults, graffiti, “irrelevance” of curricula, desperate need for endowment and disagreements with the Connecticut legislature.

    Serious American students of theology and divinity particularly in New England regarded Hebrew as a classical language along with Greek and Latin and essential for the study of the Hebrew Bible in the original words. The Reverend Ezra Stiles, president of the college from 1778 to 1795, brought with him his interest in the Hebrew language as a vehicle for studying ancient Biblical texts in their original language (as was common in other schools) requiring all freshmen to study Hebrew (in contrast to Harvard, where only upperclassmen were required to study the language) and is responsible for the Hebrew phrase אורים ותמים (Urim and Thummim) on the Yale seal. A 1746 graduate of Yale, Stiles came to the college with experience in education, having played an integral role in the founding of Brown University(US), in addition to having been a minister. Stiles’ greatest challenge occurred in July 1779 when British forces occupied New Haven and threatened to raze the college. However, Yale graduate Edmund Fanning, Secretary to the British General in command of the occupation, intervened and the college was saved. In 1803, Fanning was granted an honorary degree LL.D. for his efforts.

    Students

    As the only college in Connecticut from 1701 to 1823, Yale educated the sons of the elite. Punishable offenses for students included cardplaying; tavern-going; destruction of college property; and acts of disobedience to college authorities. During this period, Harvard was distinctive for the stability and maturity of its tutor corps, while Yale had youth and zeal on its side.

    The emphasis on classics gave rise to a number of private student societies, open only by invitation, which arose primarily as forums for discussions of modern scholarship literature and politics. The first such organizations were debating societies: Crotonia in 1738, Linonia in 1753 and Brothers in Unity in 1768. While the societies no longer exist, commemorations to them can be found with names given to campus structures, like Brothers in Unity Courtyard in Branford College.

    19th century

    The Yale Report of 1828 was a dogmatic defense of the Latin and Greek curriculum against critics who wanted more courses in modern languages, mathematics, and science. Unlike higher education in Europe, there was no national curriculum for colleges and universities in the United States. In the competition for students and financial support, college leaders strove to keep current with demands for innovation. At the same time, they realized that a significant portion of their students and prospective students demanded a classical background. The Yale report meant the classics would not be abandoned. During this period, all institutions experimented with changes in the curriculum, often resulting in a dual-track curriculum. In the decentralized environment of higher education in the United States, balancing change with tradition was a common challenge because it was difficult for an institution to be completely modern or completely classical. A group of professors at Yale and New Haven Congregationalist ministers articulated a conservative response to the changes brought about by the Victorian culture. They concentrated on developing a person possessed of religious values strong enough to sufficiently resist temptations from within yet flexible enough to adjust to the ‘isms’ (professionalism; materialism; individualism; and consumerism) tempting him from without. William Graham Sumner, professor from 1872 to 1909, taught in the emerging disciplines of economics and sociology to overflowing classrooms of students. Sumner bested President Noah Porter, who disliked the social sciences and wanted Yale to lock into its traditions of classical education. Porter objected to Sumner’s use of a textbook by Herbert Spencer that espoused agnostic materialism because it might harm students.

    Until 1887, the legal name of the university was “The President and Fellows of Yale College, in New Haven.” In 1887, under an act passed by the Connecticut General Assembly, Yale was renamed to the present “Yale University.”

    Sports and debate

    The Revolutionary War soldier Nathan Hale (Yale 1773) was the prototype of the Yale ideal in the early 19th century: a manly yet aristocratic scholar, equally well-versed in knowledge and sports, and a patriot who “regretted” that he “had but one life to lose” for his country. Western painter Frederic Remington (Yale 1900) was an artist whose heroes gloried in combat and tests of strength in the Wild West. The fictional, turn-of-the-20th-century Yale man Frank Merriwell embodied the heroic ideal without racial prejudice, and his fictional successor Frank Stover in the novel Stover at Yale (1911) questioned the business mentality that had become prevalent at the school. Increasingly the students turned to athletic stars as their heroes, especially since winning the big game became the goal of the student body, and the alumni, as well as the team itself.

    Along with Harvard and Princeton University(US), Yale students rejected British concepts about ‘amateurism’ in sports and constructed athletic programs that were uniquely American, such as football. The Harvard–Yale football rivalry began in 1875. Between 1892, when Harvard and Yale met in one of the first intercollegiate debates and 1909 (the year of the first Triangular Debate of Harvard, Yale and Princeton) the rhetoric, symbolism, and metaphors used in athletics were used to frame these early debates. Debates were covered on front pages of college newspapers and emphasized in yearbooks, and team members even received the equivalent of athletic letters for their jackets. There even were rallies sending off the debating teams to matches, but the debates never attained the broad appeal that athletics enjoyed. One reason may be that debates do not have a clear winner, as is the case in sports, and that scoring is subjective. In addition, with late 19th-century concerns about the impact of modern life on the human body, athletics offered hope that neither the individual nor the society was coming apart.

    In 1909–10, football faced a crisis resulting from the failure of the previous reforms of 1905–06 to solve the problem of serious injuries. There was a mood of alarm and mistrust, and, while the crisis was developing, the presidents of Harvard, Yale, and Princeton developed a project to reform the sport and forestall possible radical changes forced by government upon the sport. President Arthur Hadley of Yale, A. Lawrence Lowell of Harvard, and Woodrow Wilson of Princeton worked to develop moderate changes to reduce injuries. Their attempts, however, were reduced by rebellion against the rules committee and formation of the Intercollegiate Athletic Association. The big three had tried to operate independently of the majority, but changes did reduce injuries.

    Expansion

    Yale expanded gradually, establishing the Yale School of Medicine (1810); Yale Divinity School (1822); Yale Law School (1843); Yale Graduate School of Arts and Sciences (1847); the Sheffield Scientific School (1847); and the Yale School of Fine Arts (1869). In 1887, as the college continued to grow under the presidency of Timothy Dwight V, Yale College was renamed Yale University, with the name Yale College subsequently applied to the undergraduate college. The university would later add the Yale School of Music (1894); the Yale School of Forestry & Environmental Studies (founded by Gifford Pinchot in 1900); the Yale School of Public Health (1915); the Yale School of Nursing (1923); the Yale School of Drama (1955); the Yale Physician Associate Program (1973); the Yale School of Management (1976); and the Jackson School of Global Affairs which will open in 2022. It would also reorganize its relationship with the Sheffield Scientific School.

    Expansion caused controversy about Yale’s new roles. Noah Porter, moral philosopher, was president from 1871 to 1886. During an age of tremendous expansion in higher education, Porter resisted the rise of the new research university, claiming that an eager embrace of its ideals would corrupt undergraduate education. Many of Porter’s contemporaries criticized his administration, and historians since have disparaged his leadership. Levesque argues Porter was not a simple-minded reactionary, uncritically committed to tradition, but a principled and selective conservative. He did not endorse everything old or reject everything new; rather, he sought to apply long-established ethical and pedagogical principles to a rapidly changing culture. He may have misunderstood some of the challenges of his time, but he correctly anticipated the enduring tensions that have accompanied the emergence and growth of the modern university.

    20th century

    Behavioral sciences

    Between 1925 and 1940, philanthropic foundations, especially ones connected with the Rockefellers, contributed about $7 million to support the Yale Institute of Human Relations and the affiliated Yerkes Laboratories of Primate Biology. The money went toward behavioral science research, which was supported by foundation officers who aimed to “improve mankind” under an informal, loosely defined human engineering effort. The behavioral scientists at Yale, led by President James R. Angell and psychobiologist Robert M. Yerkes, tapped into foundation largesse by crafting research programs aimed to investigate, then suggest, ways to control sexual and social behavior. For example, Yerkes analyzed chimpanzee sexual behavior in hopes of illuminating the evolutionary underpinnings of human development and providing information that could ameliorate dysfunction. Ultimately, the behavioral-science results disappointed foundation officers, who shifted their human-engineering funds toward biological sciences.

    Biology

    Slack (2003) compares three groups that conducted biological research at Yale during overlapping periods between 1910 and 1970. Yale proved important as a site for this research. The leaders of these groups were Ross Granville Harrison; Grace E. Pickford; and G. Evelyn Hutchinson and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology; endocrinology; and ecology, respectively, over a long period of time. Harrison’s group is shown to have been a classic research school. Pickford’s and Hutchinson’s were not. Pickford’s group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and postgraduate students were extremely productive, but in diverse areas of ecology rather than one focused area of research or the use of one set of research tools. Hutchinson’s example shows that new models for research groups are needed, especially for those that include extensive field research.

    Medicine

    Milton Winternitz led the Yale School of Medicine as its dean from 1920 to 1935. Dedicated to the new scientific medicine established in Germany, he was equally fervent about “social medicine” and the study of humans in their culture and environment. He established the “Yale System” of teaching, with few lectures and fewer exams, and strengthened the full-time faculty system. He also created the graduate-level Yale School of Nursing and the Psychiatry Department and built numerous new buildings. Progress toward his plans for an Institute of Human Relations, envisioned as a refuge where social scientists would collaborate with biological scientists in a holistic study of humankind, unfortunately, lasted for only a few years before the opposition of resentful anti-Semitic colleagues drove him to resign.

    Before World War II, most elite university faculties counted among their numbers few, if any, Jews, blacks, women, or other minorities. Yale was no exception. By 1980, this condition had been altered dramatically, as numerous members of those groups held faculty positions. Almost all members of the Faculty of Arts and Sciences—and some members of other faculties—teach undergraduate courses, more than 2,000 of which are offered annually.

    History and American studies

    The American studies program reflected the worldwide anti-Communist ideological struggle. Norman Holmes Pearson, who worked for the Office of Strategic Studies in London during World War II, returned to Yale and headed the new American studies program. Popular among undergraduates, the program sought to instill a sense of nationalism and national purpose. Also during the 1940s and 1950s, Wyoming millionaire William Robertson Coe made large contributions to the American studies programs at Yale University and at the University of Wyoming. Coe was concerned to celebrate the ‘values’ of the Western United States in order to meet the “threat of communism”.

    Women

    In 1793, Lucinda Foote passed the entrance exams for Yale College, but was rejected by the President on the basis of her gender. Women studied at Yale University as early as 1892, in graduate-level programs at the Yale Graduate School of Arts and Sciences.

    In 1966, Yale began discussions with its sister school Vassar College(US) about merging to foster coeducation at the undergraduate level. Vassar, then all-female and part of the Seven Sisters—elite higher education schools that historically served as sister institutions to the Ivy League when most Ivy League institutions still only admitted men—tentatively accepted, but then declined the invitation. Both schools introduced coeducation independently in 1969. Amy Solomon was the first woman to register as a Yale undergraduate; she was also the first woman at Yale to join an undergraduate society, St. Anthony Hall. The undergraduate class of 1973 was the first class to have women starting from freshman year; at the time, all undergraduate women were housed in Vanderbilt Hall at the south end of Old Campus.

    A decade into co-education, student assault and harassment by faculty became the impetus for the trailblazing lawsuit Alexander v. Yale. In the late 1970s, a group of students and one faculty member sued Yale for its failure to curtail campus sexual harassment by especially male faculty. The case was party built from a 1977 report authored by plaintiff Ann Olivarius, now a feminist attorney known for fighting sexual harassment, A report to the Yale Corporation from the Yale Undergraduate Women’s Caucus. This case was the first to use Title IX to argue and establish that the sexual harassment of female students can be considered illegal sex discrimination. The plaintiffs in the case were Olivarius, Ronni Alexander (now a professor at Kobe University[神戸大学; Kōbe daigaku](JP)); Margery Reifler (works in the Los Angeles film industry), Pamela Price (civil rights attorney in California), and Lisa E. Stone (works at Anti-Defamation League). They were joined by Yale classics professor John “Jack” J. Winkler, who died in 1990. The lawsuit, brought partly by Catharine MacKinnon, alleged rape, fondling, and offers of higher grades for sex by several Yale faculty, including Keith Brion professor of flute and Director of Bands; Political Science professor Raymond Duvall (now at the University of Minnesota(US)); English professor Michael Cooke and coach of the field hockey team, Richard Kentwell. While unsuccessful in the courts, the legal reasoning behind the case changed the landscape of sex discrimination law and resulted in the establishment of Yale’s Grievance Board and the Yale Women’s Center. In March 2011 a Title IX complaint was filed against Yale by students and recent graduates, including editors of Yale’s feminist magazine Broad Recognition, alleging that the university had a hostile sexual climate. In response, the university formed a Title IX steering committee to address complaints of sexual misconduct. Afterwards, universities and colleges throughout the US also established sexual harassment grievance procedures.

    Class

    Yale, like other Ivy League schools, instituted policies in the early 20th century designed to maintain the proportion of white Protestants from notable families in the student body, and was one of the last of the Ivies to eliminate such preferences, beginning with the class of 1970.

    Town–gown relations

    Yale has a complicated relationship with its home city; for example, thousands of students volunteer every year in a myriad of community organizations, but city officials, who decry Yale’s exemption from local property taxes, have long pressed the university to do more to help. Under President Levin, Yale has financially supported many of New Haven’s efforts to reinvigorate the city. Evidence suggests that the town and gown relationships are mutually beneficial. Still, the economic power of the university increased dramatically with its financial success amid a decline in the local economy.

    21st century

    In 2006, Yale and Peking University [北京大学](CN) established a Joint Undergraduate Program in Beijing, an exchange program allowing Yale students to spend a semester living and studying with PKU honor students. In July 2012, the Yale University-PKU Program ended due to weak participation.

    In 2007 outgoing Yale President Rick Levin characterized Yale’s institutional priorities: “First, among the nation’s finest research universities, Yale is distinctively committed to excellence in undergraduate education. Second, in our graduate and professional schools, as well as in Yale College, we are committed to the education of leaders.”

    In 2009, former British Prime Minister Tony Blair picked Yale as one location – the others are Britain’s Durham University(UK) and Universiti Teknologi Mara (MY) – for the Tony Blair Faith Foundation’s United States Faith and Globalization Initiative. As of 2009, former Mexican President Ernesto Zedillo is the director of the Yale Center for the Study of Globalization and teaches an undergraduate seminar, Debating Globalization. As of 2009, former presidential candidate and DNC chair Howard Dean teaches a residential college seminar, Understanding Politics and Politicians. Also in 2009, an alliance was formed among Yale, University College London(UK), and both schools’ affiliated hospital complexes to conduct research focused on the direct improvement of patient care—a growing field known as translational medicine. President Richard Levin noted that Yale has hundreds of other partnerships across the world, but “no existing collaboration matches the scale of the new partnership with UCL”.

    In August 2013, a new partnership with the National University of Singapore(SG) led to the opening of Yale-NUS College in Singapore, a joint effort to create a new liberal arts college in Asia featuring a curriculum including both Western and Asian traditions.

    In 2020, in the wake of protests around the world focused on racial relations and criminal justice reform, the #CancelYale movement demanded that Elihu Yale’s name be removed from Yale University. Yale was president of the East India Company, a trading company that traded slaves as well as goods, and his singularly large donation led to Yale relying on money from the slave-trade for its first scholarships and endowments.

    In August 2020, the US Justice Department claimed that Yale discriminated against Asian and white candidates on the basis of their race. The university, however, denied the report. In early February 2021, under the new Biden administration, the Justice Department withdrew the lawsuit. The group, Students for Fair Admissions, known for a similar lawsuit against Harvard alleging the same issue, plans to refile the lawsuit.

    Yale alumni in Politics

    The Boston Globe wrote that “if there’s one school that can lay claim to educating the nation’s top national leaders over the past three decades, it’s Yale”. Yale alumni were represented on the Democratic or Republican ticket in every U.S. presidential election between 1972 and 2004. Yale-educated Presidents since the end of the Vietnam War include Gerald Ford; George H.W. Bush; Bill Clinton; and George W. Bush. Major-party nominees during this period include Hillary Clinton (2016); John Kerry (2004); Joseph Lieberman (Vice President, 2000); and Sargent Shriver (Vice President, 1972). Other Yale alumni who have made serious bids for the Presidency during this period include Amy Klobuchar (2020); Tom Steyer (2020); Ben Carson (2016); Howard Dean (2004); Gary Hart (1984 and 1988); Paul Tsongas (1992); Pat Robertson (1988); and Jerry Brown (1976, 1980, 1992).

    Several explanations have been offered for Yale’s representation in national elections since the end of the Vietnam War. Various sources note the spirit of campus activism that has existed at Yale since the 1960s, and the intellectual influence of Reverend William Sloane Coffin on many of the future candidates. Yale President Richard Levin attributes the run to Yale’s focus on creating “a laboratory for future leaders,” an institutional priority that began during the tenure of Yale Presidents Alfred Whitney Griswold and Kingman Brewster. Richard H. Brodhead, former dean of Yale College and now president of Duke University(US), stated: “We do give very significant attention to orientation to the community in our admissions, and there is a very strong tradition of volunteerism at Yale.” Yale historian Gaddis Smith notes “an ethos of organized activity” at Yale during the 20th century that led John Kerry to lead the Yale Political Union’s Liberal Party; George Pataki the Conservative Party; and Joseph Lieberman to manage the Yale Daily News. Camille Paglia points to a history of networking and elitism: “It has to do with a web of friendships and affiliations built up in school.” CNN suggests that George W. Bush benefited from preferential admissions policies for the “son and grandson of alumni”, and for a “member of a politically influential family”. New York Times correspondent Elisabeth Bumiller and The Atlantic Monthly correspondent James Fallows credit the culture of community and cooperation that exists between students, faculty, and administration, which downplays self-interest and reinforces commitment to others.

    During the 1988 presidential election, George H. W. Bush (Yale ’48) derided Michael Dukakis for having “foreign-policy views born in Harvard Yard’s boutique”. When challenged on the distinction between Dukakis’ Harvard connection and his own Yale background, he said that, unlike Harvard, Yale’s reputation was “so diffuse, there isn’t a symbol, I don’t think, in the Yale situation, any symbolism in it” and said Yale did not share Harvard’s reputation for “liberalism and elitism”. In 2004 Howard Dean stated, “In some ways, I consider myself separate from the other three (Yale) candidates of 2004. Yale changed so much between the class of ’68 and the class of ’71. My class was the first class to have women in it; it was the first class to have a significant effort to recruit African Americans. It was an extraordinary time, and in that span of time is the change of an entire generation”.

    Leadership

    The President and Fellows of Yale College, also known as the Yale Corporation, or board of trustees, is the governing body of the university and consists of thirteen standing committees with separate responsibilities outlined in the by-laws. The corporation has 19 members: three ex officio members, ten successor trustees, and six elected alumni fellows.

    Yale’s former president Richard C. Levin was, at the time, one of the highest paid university presidents in the United States. Yale’s succeeding president Peter Salovey ranks 40th.

    The Yale Provost’s Office and similar executive positions have launched several women into prominent university executive positions. In 1977, Provost Hanna Holborn Gray was appointed interim President of Yale and later went on to become President of the University of Chicago(US), being the first woman to hold either position at each respective school. In 1994, Provost Judith Rodin became the first permanent female president of an Ivy League institution at the University of Pennsylvania(US). In 2002, Provost Alison Richard became the Vice-Chancellor of the University of Cambridge(UK). In 2003, the Dean of the Divinity School, Rebecca Chopp, was appointed president of Colgate University(US) and later went on to serve as the President of the Swarthmore College(US) in 2009, and then the first female chancellor of the University of Denver(US) in 2014. In 2004, Provost Dr. Susan Hockfield became the President of the Massachusetts Institute of Technology (US). In 2004, Dean of the Nursing school, Catherine Gilliss, was appointed the Dean of Duke University’s School of Nursing and Vice Chancellor for Nursing Affairs. In 2007, Deputy Provost H. Kim Bottomly was named President of Wellesley College(US).

    Similar examples for men who’ve served in Yale leadership positions can also be found. In 2004, Dean of Yale College Richard H. Brodhead was appointed as the President of Duke University(US). In 2008, Provost Andrew Hamilton was confirmed to be the Vice Chancellor of the University of Oxford(UK).

    The university has three major academic components: Yale College (the undergraduate program); the Graduate School of Arts and Sciences; and the professional schools.

    Campus

    Yale’s central campus in downtown New Haven covers 260 acres (1.1 km2) and comprises its main, historic campus and a medical campus adjacent to the Yale–New Haven Hospital. In western New Haven, the university holds 500 acres (2.0 km2) of athletic facilities, including the Yale Golf Course. In 2008, Yale purchased the 17-building, 136-acre (0.55 km2) former Bayer HealthCare complex in West Haven, Connecticut, the buildings of which are now used as laboratory and research space. Yale also owns seven forests in Connecticut, Vermont, and New Hampshire—the largest of which is the 7,840-acre (31.7 km2) Yale-Myers Forest in Connecticut’s Quiet Corner—and nature preserves including Horse Island.

    Yale is noted for its largely Collegiate Gothic campus as well as several iconic modern buildings commonly discussed in architectural history survey courses: Louis Kahn’s Yale Art Gallery and Center for British Art; Eero Saarinen’s Ingalls Rink and Ezra Stiles and Morse Colleges; and Paul Rudolph’s Art & Architecture Building. Yale also owns and has restored many noteworthy 19th-century mansions along Hillhouse Avenue, which was considered the most beautiful street in America by Charles Dickens when he visited the United States in the 1840s. In 2011, Travel+Leisure listed the Yale campus as one of the most beautiful in the United States.

    Many of Yale’s buildings were constructed in the Collegiate Gothic architecture style from 1917 to 1931, financed largely by Edward S. Harkness, including the Yale Drama School. Stone sculpture built into the walls of the buildings portray contemporary college personalities, such as a writer; an athlete; a tea-drinking socialite; and a student who has fallen asleep while reading. Similarly, the decorative friezes on the buildings depict contemporary scenes, like a policemen chasing a robber and arresting a prostitute (on the wall of the Law School) or a student relaxing with a mug of beer and a cigarette. The architect, James Gamble Rogers, faux-aged these buildings by splashing the walls with acid, deliberately breaking their leaded glass windows and repairing them in the style of the Middle Ages and creating niches for decorative statuary but leaving them empty to simulate loss or theft over the ages. In fact, the buildings merely simulate Middle Ages architecture, for though they appear to be constructed of solid stone blocks in the authentic manner, most actually have steel framing as was commonly used in 1930. One exception is Harkness Tower, 216 feet (66 m) tall, which was originally a free-standing stone structure. It was reinforced in 1964 to allow the installation of the Yale Memorial Carillon.

    Other examples of the Gothic style are on the Old Campus by architects like Henry Austin; Charles C. Haight; and Russell Sturgis. Several are associated with members of the Vanderbilt family, including Vanderbilt Hall; Phelps Hall; St. Anthony Hall (a commission for member Frederick William Vanderbilt); the Mason, Sloane and Osborn laboratories; dormitories for the Sheffield Scientific School (the engineering and sciences school at Yale until 1956) and elements of Silliman College, the largest residential college.

    The oldest building on campus, Connecticut Hall (built in 1750), is in the Georgian style. Georgian-style buildings erected from 1929 to 1933 include Timothy Dwight College, Pierson College, and Davenport College, except the latter’s east, York Street façade, which was constructed in the Gothic style to coordinate with adjacent structures.

    Interior of Beinecke Library

    The Beinecke Rare Book and Manuscript Library, designed by Gordon Bunshaft of Skidmore, Owings & Merrill, is one of the largest buildings in the world reserved exclusively for the preservation of rare books and manuscripts. The library includes a six-story above-ground tower of book stacks, filled with 180,000 volumes, that is surrounded by large translucent Vermont marble panels and a steel and granite truss. The panels act as windows and subdue direct sunlight while also diffusing the light in warm hues throughout the interior. Near the library is a sunken courtyard, with sculptures by Isamu Noguchi that are said to represent time (the pyramid), the sun (the circle), and chance (the cube). The library is located near the center of the university in Hewitt Quadrangle, which is now more commonly referred to as “Beinecke Plaza.”

    Alumnus Eero Saarinen, Finnish-American architect of such notable structures as the Gateway Arch in St. Louis; Washington Dulles International Airport main terminal; Bell Labs Holmdel Complex; and the CBS Building in Manhattan, designed Ingalls Rink, dedicated in 1959, as well as the residential colleges Ezra Stiles and Morse. These latter were modeled after the medieval Italian hill town of San Gimignano – a prototype chosen for the town’s pedestrian-friendly milieu and fortress-like stone towers. These tower forms at Yale act in counterpoint to the college’s many Gothic spires and Georgian cupolas.

    Yale’s Office of Sustainability develops and implements sustainability practices at Yale. Yale is committed to reduce its greenhouse gas emissions 10% below 1990 levels by the year 2020. As part of this commitment, the university allocates renewable energy credits to offset some of the energy used by residential colleges. Eleven campus buildings are candidates for LEED design and certification. Yale Sustainable Food Project initiated the introduction of local organic vegetables fruits and beef to all residential college dining halls. Yale was listed as a Campus Sustainability Leader on the Sustainable Endowments Institute’s College Sustainability Report Card 2008, and received a “B+” grade overall.

    Notable nonresidential campus buildings

    Notable nonresidential campus buildings and landmarks include Battell Chapel; Beinecke Rare Book Library; Harkness Tower; Ingalls Rink; Kline Biology Tower; Osborne Memorial Laboratories; Payne Whitney Gymnasium; Peabody Museum of Natural History; Sterling Hall of Medicine; Sterling Law Buildings; Sterling Memorial Library; Woolsey Hall; Yale Center for British Art; Yale University Art Gallery; Yale Art & Architecture Building and the Paul Mellon Centre for Studies in British Art in London.

    Yale’s secret society buildings (some of which are called “tombs”) were built both to be private yet unmistakable. A diversity of architectural styles is represented: Berzelius; Donn Barber in an austere cube with classical detailing (erected in 1908 or 1910); Book and Snake; Louis R. Metcalfe in a Greek Ionic style (erected in 1901); Elihu, architect unknown but built in a Colonial style (constructed on an early 17th-century foundation although the building is from the 18th century); Mace and Chain, in a late colonial early Victorian style (built in 1823). (Interior moulding is said to have belonged to Benedict Arnold); Manuscript Society, King Lui-Wu with Dan Kniley responsible for landscaping and Josef Albers for the brickwork intaglio mural. Buildings constructed in a mid-century modern style: Scroll and Key; Richard Morris Hunt in a Moorish- or Islamic-inspired Beaux-Arts style (erected 1869–70); Skull and Bones; possibly Alexander Jackson Davis or Henry Austin in an Egypto-Doric style utilizing Brownstone (in 1856 the first wing was completed, in 1903 the second wing, 1911 the Neo-Gothic towers in rear garden were completed); St. Elmo, (former tomb) Kenneth M. Murchison, 1912, designs inspired by Elizabethan manor. Current location, brick colonial; and Wolf’s Head, Bertram Grosvenor Goodhue, erected 1923–1924, Collegiate Gothic.

    Relationship with New Haven

    Yale is the largest taxpayer and employer in the City of New Haven, and has often buoyed the city’s economy and communities. Yale, however has consistently opposed paying a tax on its academic property. Yale’s Art Galleries, along with many other university resources, are free and openly accessible. Yale also funds the New Haven Promise program, paying full tuition for eligible students from New Haven public schools.

    From Cornell Chronicle (US) : “Trace gas phosphine points to volcanic activity on Venus” 

    From Cornell Chronicle (US)

    July 12, 2021
    Blaine Friedlander
    bpf2@cornell.edu

    1
    Maat Mons, a large volcano on Venus, is shown in this 1991 simulated-color radar image from National Aeronautics Space Agency (US)’s Magellan spacecraft mission.

    Scientists last autumn revealed that the gas phosphine was found in trace amounts in Venus’ upper atmosphere. That discovery promised the slim possibility that phosphine serves as a biological signature for the hot, toxic planet.

    Now Cornell scientists say the phosphine’s chemical fingerprints support a different and important scientific find: evidence of explosive volcanoes on the mysterious planet.

    “The phosphine is not telling us about the biology of Venus,” said Jonathan Lunine, the David C. Duncan Professor in Physical Sciences and chair of the Department of Astronomy in the College of Arts and Sciences. “It’s telling us about the geology. Science is pointing to a planet that has active explosive volcanism today or in the very recent past.”

    Lunine and Ngoc Truong, a doctoral candidate in geology, have authored the study, “Volcanically Extruded Phosphides as an Abiotic Source of Venusian Phosphine,” published July 12 in the PNAS.

    Truong and Lunine argue that volcanism is the means for phosphine to get into Venus’ upper atmosphere, after examining observations from the ground-based, submillimeter-wavelength James Clerk Maxwell Telescope atop Mauna Kea in Hawaii, and the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile.

    “Volcanism could supply enough phosphide to produce phosphine,” Truong said. “The chemistry implies that phosphine derives from explosive volcanoes on Venus, not biological sources.”

    Our planetary neighbor broils with an almost 900-degree Fahrenheit average surface temperature and features a carbon dioxide-filled atmosphere enveloped in sulfuric acid clouds, according to NASA.

    If Venus has phosphide – a form of phosphorous present in the planet’s deep mantle – and, if it is brought to the surface in an explosive, volcanic way and then injected into the atmosphere, those phosphides react with the Venusian atmosphere’s sulfuric acid to form phosphine, Truong said.

    He found published laboratory data confirming that the phosphide reacts with sulfuric acid to produce phosphines efficiently.

    Volcanism on Venus is not necessarily surprising, Lunine said. But while “our phosphine model suggests explosive volcanism occurring, radar images from the Magellan spacecraft in the 1990s show some geologic features could support this.”

    In 1978, on NASA’s Pioneer Venus orbiter mission, scientists uncovered variations of sulfur dioxide in Venus’ upper atmosphere, hinting at the prospect of explosive volcanism, Truong said, similar to the scale of Earth’s Krakatoa volcanic eruption in Indonesia in 1883.

    Said Truong: “Confirming explosive volcanism on Venus through the gas phosphine was totally unexpected.”

    Funding for the research was provided by the NASA Goddard Space Flight Center (US) in Greenbelt, Maryland.

    Stem Education Coalition

    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 (US) 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 Jacobs Technion-Cornell Institute(US) 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 SUNY – The State University of New York (US) 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(US) 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 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(US), 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(US) 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(US)’s JPL-Caltech (US) 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 (US) and the Metropolitan University of Puerto Rico [Universidad Metropolitana de Puerto Rico](US).

    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 an National Science Foundation (US) 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(US), 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 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.

    From GFZ German Research Centre Helmholtz Centre for Geosciences Potsdam: “Continental pirouettes” 

    From GFZ German Research Centre Helmholtz Centre for Geosciences Potsdam

    1

    The plates of the Earth’s crust perform complicated movements that can be attributed to quite simple mechanisms. That is the short version of the explanation of a rift that began to tear the world apart over a length of several thousand kilometers 105 million years ago. The scientific explanation appears today in the journal Nature Geoscience.

    According to the paper, a super volcano split the Earth’s crust over a length of 7,500 kilometers, pushing the Indian Plate away from the African Plate. The cause was a “plume” in the Earth’s mantle, i.e. a surge of hot material that wells upwards like an atomic mushroom cloud in super slow motion. It has long been known that the Indian landmass thus made its way northward and bumped into Eurasia. But a seemingly counterintuitive east-west movement of the continental plates was also part of the process. This is supported by calculations by a team led by Dutch scientist Douwe van Hinsbergen (Utrecht University [ Universiteit Utrecht] (NL)) and Bernhard Steinberger (GFZ German Research Centre for Geosciences).

    According to the findings, the Indian Plate did not simply move away from Africa, but rotated in the process. The reason for this is the subcontinent, whose land mass acts on the much larger continental plate like an axis around which the entire plate rotates. In the south, the scissors opened, in the north they closed – there, mountain-building processes and the subduction of crustal plates were induced.

    This has dramatic effects up to the present time: The subduction processes continue and trigger earthquakes again and again in the Mediterranean region between Cyprus and Turkey. The traces of the plume and the supervolcano can still be identified today. They are flood basalts on Madagascar and in the southwest of India. They testify to immense volcanic activity fed by the mantle plume.

    Bernhard Steinberger has calculated the movement and pressure that the super volcano near present-day Madagascar could cause further north on the Arabian Peninsula and in what is now the Mediterranean. He has also published a “kitchen table experiment on Youtube” which illustrates the movements.

    The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences

    Our vision

    The future can only be secured by those who understand the System Earth and its interactions with Man: We develop a profound understanding of systems and processes of the solid Earth together with strategies and options for action to address global change and its regional impacts, to understand natural hazards and to minimize associated risks, as well as to assess the human impact on System Earth.
    Earth System Science for the Future

    The GFZ is Germany’s national research center for the solid Earth Sciences. Our mission is to deepen the knowledge of the dynamics of the solid Earth, and to develop solutions for grand challenges facing society. These challenges include anticipating the hazards arising from the Earth’s dynamic systems and mitigating the associated risks to society; securing our habitat under the pressure of global change; and supplying energy and mineral resources for a rapidly growing population in a sustainable manner and without harming the environment.

    These challenges are inextricably linked with the dynamics of planet Earth, not just the solid Earth and the surface on which we live, but also the hydrosphere, atmosphere, and biosphere, and the chemical, physical, and biological processes that connect them. Hence, we view our planet as a system with interacting components. We investigate the structure and history of the Earth, its properties, and the dynamics of its interior and surface, and we use our fundamental understanding to develop solutions needed to maintain planet Earth as a safe and supportive habitat.

    Our expertise

    In pursuit of our mission, we have developed a comprehensive spectrum of expertise in geodesy, geophysics, geology, mineralogy, geochemistry, physics, geomorphology, geobiosciences, mathematics, and engineering. This is complemented by our deep methodological and technological knowhow and innovation. We are responsible for the long-term operation of expansive instrument networks, arrays and observatories, as well as data and analytical infrastructures. To accomplish our large-scale tasks, we have established MESI, the worldwide unique Modular Earth Science Infrastructure.

    Our research is organized in a matrix structure, with disciplinary competences grouped in four scientific departments. The departments guarantee the development and continuity of disciplinary skills, methods, and infrastructures. This is an indispensable foundation for our ability to engage with evolving scientific insights, new technologies, and unexpected, pressing challenges of societal relevance.

    The grand challenges and the complexity of system Earth on the other hand, require a close multidisciplinary interaction and integration across scientific competence fields to secure advances in understanding and solutions. For these reasons, and to achieve our scientific mission, we coordinate our research via five Research Units (RU) that foster the required long-term research collaborations and that transcend the organizational / management units. These five RUs are:

    Global Processes – Integrated monitoring and modelling: How are linked processes controlling the global dynamics of the Earth and change in the Earth System?

    Plate Boundary Systems – Understanding the dynamics that affect the human habitat: How do the dynamic processes of the solid Earth’s most dynamic systems function and how do they control related hazards and resource formation?

    Earth Surface and Climate Interactions – Probing records to constrain mechanisms and sensitivities: How does climate change today and in the past affect the Earth surface and how do surface processes, in turn, influence the atmosphere and climate?

    Natural Hazards – Understanding risks and safeguarding the human habitat: How can we better predict and understand natural hazards, their dynamics, and their consequences?

    Georesources and Geoenergy – Raw materials and contributions to the energy transition: How can georesources and the geological subsurface be used in a sustainable way?

The total volume of erupted deposits may exceed 5,000 cubic kilometers. Credit: Steve Self, University of California-Berkeley (US).

    A massive volcanic eruption in Indonesia about 74,000 years ago likely caused severe climate disruption in many areas of the globe, but early human populations were sheltered from the worst effects, according to a Rutgers-led study.

    The findings appear in the journal PNAS.

    The eruption of the Toba volcano was the largest volcanic eruption in the past two million years, but its impacts on climate and human evolution have been unclear. Resolving this debate is important for understanding environmental changes during a key interval in human evolution.

    “We were able to use a large number of climate model simulations to resolve what seemed like a paradox,” said lead author Benjamin Black, an assistant professor in the Department of Earth and Planetary Sciences at Rutgers University-New Brunswick. “We know this eruption happened and that past climate modeling has suggested the climate consequences could have been severe, but archaeological and paleoclimate records from Africa don’t show such a dramatic response.

    “Our results suggest that we might not have been looking in the right place to see the climate response. Africa and India are relatively sheltered, whereas North America, Europe and Asia bear the brunt of the cooling,” Black said. “One intriguing aspect of this is that Neanderthals and Denisovans were living in Europe and Asia at this time, so our paper suggests evaluating the effects of the Toba eruption on those populations could merit future investigation.”

    The researchers analyzed 42 global climate model simulations in which they varied magnitude of sulfur emissions, time of year of the eruption, background climate state and sulfur injection altitude to make a probabilistic assessment of the range of climate disruptions the Toba eruption may have caused. This approach let the team account for some of the unknowns related to the eruption.

    “By using a probabilistic approach, we aim at understanding the likelihood that some regions were less impacted by Toba, considering the wide range of estimates of its size and timing, in addition to our lack of knowledge of the underlying climate state,” said Black.

    The results suggest there was likely significant regional variation in climate impacts. The simulations predict cooling in the Northern Hemisphere of at least 4°C, with regional cooling as high as 10°C depending on the model parameters. In contrast, even under the most severe eruption conditions, cooling in the Southern Hemisphere — including regions populated by early humans — was unlikely to exceed 4°C, although regions in southern Africa and India may have seen decreases in precipitation at the highest sulfur emission level.

    The results explain independent archaeological evidence suggesting the Toba eruption had modest effects on the development of hominid species in Africa. According to the authors, their ensemble simulation approach could be used to better understand other past and future explosive eruptions.

    “Our results reconcile the simulated distribution of climate impacts from the eruption with paleoclimate and archaeological records,” according to the study. “This probabilistic view of climate disruption from Earth’s most recent super-eruption underscores the uneven expected distribution of societal and environmental impacts from future very large explosive eruptions.”

    The study included researchers from the National Center for Atmospheric Research, University of Leeds and University of Cambridge, and was supported by the NSF National Center for Atmospheric Research (US) and the National Science Foundation (US).

    Rutgers, The State University of New Jersey (US), is a leading national research university and the state’s preeminent, comprehensive public institution of higher education. Rutgers is dedicated to teaching that meets the highest standards of excellence; to conducting research that breaks new ground; and to providing services, solutions, and clinical care that help individuals and the local, national, and global communities where they live.

    Founded in 1766, Rutgers teaches across the full educational spectrum: preschool to precollege; undergraduate to graduate; postdoctoral fellowships to residencies; and continuing education for professional and personal advancement.

    Rutgers University (US) is a public land-grant research university based in New Brunswick, New Jersey. Chartered in 1766, Rutgers was originally called Queen’s College, and today it is the eighth-oldest college in the United States, the second-oldest in New Jersey (after Princeton University (US)), and one of the nine U.S. colonial colleges that were chartered before the American War of Independence. In 1825, Queen’s College was renamed Rutgers College in honor of Colonel Henry Rutgers, whose substantial gift to the school had stabilized its finances during a period of uncertainty. For most of its existence, Rutgers was a private liberal arts college but it has evolved into a coeducational public research university after being designated The State University of New Jersey by the New Jersey Legislature via laws enacted in 1945 and 1956.

    Rutgers today has three distinct campuses, located in New Brunswick (including grounds in adjacent Piscataway), Newark, and Camden. The university has additional facilities elsewhere in the state, including oceanographic research facilities at the New Jersey shore. Rutgers is also a land-grant university, a sea-grant university, and the largest university in the state. Instruction is offered by 9,000 faculty members in 175 academic departments to over 45,000 undergraduate students and more than 20,000 graduate and professional students. The university is accredited by the Middle States Association of Colleges and Schools and is a member of the Big Ten Academic Alliance, the Association of American Universities (US) and the Universities Research Association (US). Over the years, Rutgers has been considered a Public Ivy.

    Research

    Rutgers is home to the Rutgers University Center for Cognitive Science, also known as RUCCS. This research center hosts researchers in psychology, linguistics, computer science, philosophy, electrical engineering, and anthropology.

    It was at Rutgers that Selman Waksman (1888–1973) discovered several antibiotics, including actinomycin, clavacin, streptothricin, grisein, neomycin, fradicin, candicidin, candidin, and others. Waksman, along with graduate student Albert Schatz (1920–2005), discovered streptomycin—a versatile antibiotic that was to be the first applied to cure tuberculosis. For this discovery, Waksman received the Nobel Prize for Medicine in 1952.

    Rutgers developed water-soluble sustained release polymers, tetraploids, robotic hands, artificial bovine insemination, and the ceramic tiles for the heat shield on the Space Shuttle. In health related field, Rutgers has the Environmental & Occupational Health Science Institute (EOHSI).

    Rutgers is also home to the RCSB Protein Data bank, “…an information portal to Biological Macromolecular Structures’ cohosted with the San Diego Supercomputer Center (US). This database is the authoritative research tool for bioinformaticists using protein primary, secondary and tertiary structures worldwide….”

    Rutgers is home to the Rutgers Cooperative Research & Extension office, which is run by the Agricultural and Experiment Station with the support of local government. The institution provides research & education to the local farming and agro industrial community in 19 of the 21 counties of the state and educational outreach programs offered through the New Jersey Agricultural Experiment Station Office of Continuing Professional Education.

    Rutgers University Cell and DNA Repository (RUCDR) is the largest university based repository in the world and has received awards worth more than $57.8 million from the National Institutes of Health (US). One will fund genetic studies of mental disorders and the other will support investigations into the causes of digestive, liver and kidney diseases, and diabetes. RUCDR activities will enable gene discovery leading to diagnoses, treatments and, eventually, cures for these diseases. RUCDR assists researchers throughout the world by providing the highest quality biomaterials, technical consultation, and logistical support.

    Rutgers–Camden is home to the nation’s PhD granting Department of Childhood Studies. This department, in conjunction with the Center for Children and Childhood Studies, also on the Camden campus, conducts interdisciplinary research which combines methodologies and research practices of sociology, psychology, literature, anthropology and other disciplines into the study of childhoods internationally.

    Rutgers is home to several National Science Foundation (US) IGERT fellowships that support interdisciplinary scientific research at the graduate-level. Highly selective fellowships are available in the following areas: Perceptual Science, Stem Cell Science and Engineering, Nanotechnology for Clean Energy, Renewable and Sustainable Fuels Solutions, and Nanopharmaceutical Engineering.

    Rutgers also maintains the Office of Research Alliances that focuses on working with companies to increase engagement with the university’s faculty members, staff and extensive resources on the four campuses.

    Scientists are set to uncover the secrets of a rare meteorite and possibly the origins of oceans and life on Earth, thanks to Science and Technology Facilities Council (STFC) (UK) funding.

    Research carried out on the meteorite, which fell in the UK earlier this year, suggests that the space rock dates back to the beginning of the Solar System, 4.5 billion years ago.

    The meteorite has now been officially classified, thanks in part to the STFC-funded studies on the sample.

    The Winchcombe meteorite, aptly named after the Gloucestershire town where it landed, is an extremely rare type called a carbonaceous chondrite. It is a stony meteorite rich in water and organic matter which has retained its chemistry from the formation of the solar system. Initial analyses showing Winchcombe to be a member of the CM (“Mighei-like”) group of carbonaceous chondrites have now been formally approved by the Meteoritical Society.

    STFC provided an urgency grant in order to help fund the work of planetary scientists across the UK. The funding has enabled the Natural History Museum to invest in state-of-the-art curation facilities to preserve the meteorite, and also supported time-sensitive mineralogical and organic analyses in specialist laboratories at several leading UK institutions.

    Dr Ashley King, a UK Research and Innovation (UKRI) Future Leaders Fellow in the Department of Earth Sciences at the Natural History Museum, said: “We are grateful for the funding STFC has provided. Winchcombe is the first meteorite fall to be recovered in the UK for 30 years and the first ever carbonaceous chondrite to be recovered in our country. STFC’s funding is aiding us with this unique opportunity to discover the origins of water and life on Earth. Through the funding, we have been able to invest in state-of-the-art equipment that has contributed to our analysis and research into the Winchcombe meteorite.”

    The meteorite was tracked using images and video footage from the UK Fireball Alliance (UKFAll), a collaboration between the UK’s meteor camera networks that includes the UK Fireball Network, which is funded by STFC. Fragments were then quickly located and recovered. Since the discovery, UK scientists have been studying Winchcombe to understand its mineralogy and chemistry to learn about how the Solar System formed.

    Dr Luke Daly from the University of Glasgow and co-lead of the UK Fireball Network, said: “Being able to investigate Winchcombe is a dream come true. Many of us have spent our entire careers studying this type of rare meteorite. We are also involved in JAXA’s Hayabusa2 and NASA’s OSIRIS-REx missions, which aim to return pristine samples of carbonaceous asteroids to the Earth.

    For a carbonaceous chondrite meteorite to fall in the UK, and for it to be recovered so quickly and have a known orbit, is a really special event and a fantastic opportunity for the UK planetary science community.”

    Funding from STFC enabled scientists to quickly begin the search for signs of water and organics in Winchcombe before it could be contaminated by the terrestrial environment.

    Dr Queenie Chan from Royal Holloway, University of London (UK) added: “The teams preliminary analyses confirm that Winchcombe contains a wide range of organic material! Studying the meteorite only weeks after the fall, before any significant terrestrial contamination, means that we really are peering back in time at the ingredients present at the birth of the solar system, and learning about how they came together to make planets like the Earth.”

    A piece of the Winchcombe meteorite that was recovered during an organised search by the UK planetary science community is now on public display at London’s Natural History Museum.

    Institutions involved include:

    STFC – urgency grant is funding Natural History Museum and other STFC-funded planetary science groups.

    The University of Glasgow [Oilthigh Ghlaschu] (SCT) is the fourth oldest university in the English-speaking world and one of Scotland’s four ancient universities. It was founded in 1451. Along with the University of Edinburgh (SCT), the University was part of the Scottish Enlightenment during the 18th century. It is currently a member of Universitas 21, the international network of research universities, and the Russell Group (UK).

    In common with universities of the pre-modern era, Glasgow originally educated students primarily from wealthy backgrounds, however it became a pioneerin British higher education in the 19th century by also providing for the needs of students from the growing urban and commercial middle class. Glasgow University served all of these students by preparing them for professions: the law, medicine, civil service, teaching, and the church. It also trained smaller but growing numbers for careers in science and engineering.

    Originally located in the city’s High Street, since 1870 the main University campus has been located at Gilmorehill in the West End of the city. Additionally, a number of university buildings are located elsewhere, such as the University Marine Biological Station Millport on the Island of Cumbrae in the Firth of Clyde and the Crichton Campus in Dumfries.

    Alumni or former staff of the University include philosopher Francis Hutcheson, engineer James Watt, philosopher and economist Adam Smith, physicist Lord Kelvin, surgeon Joseph Lister, 1st Baron Lister, seven Nobel laureates, and two British Prime Ministers.

    Microscopic imperfections in rock crystals deep beneath Earth’s surface play a deciding factor in how the ground slowly moves and resets in the aftermath of major earthquakes, says new research involving the University of Cambridge.

    The stresses resulting from these defects – which are small enough to disrupt the atomic building blocks of a crystal – can transform how hot rocks beneath Earth’s crust move and in turn transfer stress back to Earth’s surface, starting the countdown to the next earthquake.

    The new study, published in Nature Communications, is the first to map out the crystal defects and surrounding force fields in detail. “They’re so tiny that we’ve only been able to observe them with the latest microscopy techniques,” said lead author Dr David Wallis from Cambridge’s Department of Earth Sciences, “But it’s clear that they can significantly influence how deep rocks move, and even govern when and where the next earthquake will happen.”

    By understanding how these crystal defects influence rocks in the Earth’s upper mantle scientists can better interpret measurements of ground motions following earthquakes, which give vital information on where stress is building up – and in turn where future earthquakes may occur.

    Earthquakes happen when pieces of Earth’s crust suddenly slip past each other along fault lines releasing stored-up energy which propagates through the Earth and causes it to shake. This movement is generally a response to the build-up of tectonic forces in the Earth’s crust, causing the surface to buckle and eventually rupture in the form of an earthquake.

    Their work reveals that the way Earth’s surface settles after an earthquake, and stores stress prior to a repeat event, can ultimately be traced to tiny defects in rock crystals from the deep.

    “If you can understand how fast these deep rocks can flow, and how long it will take to transfer stress between different areas across a fault zone, then we might be able to get better predictions of when and where the next earthquake will strike,” said Wallis.

    The team subjected olivine crystals – the most common component of the upper mantle — to a range of pressures and temperatures in order to replicate conditions of up to 100 km beneath Earth’s surface, where the rocks are so hot (roughly 1250 deg C) they move like syrup.

    Wallis likens their experiments to a blacksmith working with hot metal – at the highest temperatures, their samples were glowing white-hot and pliable.

    They observed the distorted crystal structures using a high-resolution form of electron microscopy called electron backscatter diffraction, which Wallis has pioneered on geological materials.

    Their results shed light on how hot rocks in the upper mantle can mysteriously morph from flowing almost like syrup immediately after an earthquake to becoming thick and sluggish as time passes.

    This change in thickness — or viscosity – transfers stress back to the cold and brittle rocks in the crust above, where it builds up – until the next earthquake strikes.

    The reason for this switch in behaviour has remained an open question, “We’ve known that microscale processes are a key factor controlling earthquakes for a while, but it’s been difficult to observe these tiny features in enough detail,” said Wallis. “Thanks to a state-of-the-art microscopy technique, we’ve been able to look into the crystal framework of hot, deep rocks and track down how important these miniscule defects really are”.

    Wallis and co-authors show that irregularities in the crystals become increasingly tangled over time; jostling for space due to their competing force fields – and it’s this process that causes the rocks to become more viscous.

    Until now it had been thought that this increase in viscosity was because of the competing push and pull of crystals against each other, rather than being caused by microscopic defects and their stress fields inside the crystals themselves.

    The team hope to apply their work to improving seismic hazard maps, which are often used in tectonically active areas like southern California to estimate where the next earthquake will occur. Current models, which are usually based on where earthquakes have struck in the past, and where stress must therefore be building up, only take into account the more immediate changes across a fault zone and do not consider gradual stress changes in rocks flowing deep within the Earth.

    Working with colleagues at Utrecht University [Universiteit Utrecht] (NL), Wallis also plans to apply their new lab constraints to models of ground movements following the hazardous 2004 earthquake which struck Indonesia, and the 2011 Japan quake – both of which triggered tsunamis and lead to the loss of tens of thousands of lives.

    U Cambridge Campus

    The University of Cambridge (UK) [legally The Chancellor, Masters, and Scholars of the University of Cambridge] is a collegiate public research university in Cambridge, England. Founded in 1209 Cambridge is the second-oldest university in the English-speaking world and the world’s fourth-oldest surviving university. It grew out of an association of scholars who left the University of Oxford(UK) after a dispute with townsfolk. The two ancient universities share many common features and are often jointly referred to as “Oxbridge”.

    Cambridge is formed from a variety of institutions which include 31 semi-autonomous constituent colleges and over 150 academic departments, faculties and other institutions organised into six schools. All the colleges are self-governing institutions within the university, each controlling its own membership and with its own internal structure and activities. All students are members of a college. Cambridge does not have a main campus and its colleges and central facilities are scattered throughout the city. Undergraduate teaching at Cambridge is organised around weekly small-group supervisions in the colleges – a feature unique to the Oxbridge system.

    History

    By the late 12th century the Cambridge area already had a scholarly and ecclesiastical reputation due to monks from the nearby bishopric church of Ely. However it was an incident at Oxford which is most likely to have led to the establishment of the university: three Oxford scholars were hanged by the town authorities for the death of a woman without consulting the ecclesiastical authorities who would normally take precedence (and pardon the scholars) in such a case; but were at that time in conflict with King John. Fearing more violence from the townsfolk scholars from the University of Oxford started to move away to cities such as Paris; Reading; and Cambridge. Subsequently enough scholars remained in Cambridge to form the nucleus of a new university when it had become safe enough for academia to resume at Oxford. In order to claim precedence it is common for Cambridge to trace its founding to the 1231 charter from Henry III granting it the right to discipline its own members (ius non-trahi extra) and an exemption from some taxes; Oxford was not granted similar rights until 1248.

    A bull in 1233 from Pope Gregory IX gave graduates from Cambridge the right to teach “everywhere in Christendom”. After Cambridge was described as a studium generale in a letter from Pope Nicholas IV in 1290 and confirmed as such in a bull by Pope John XXII in 1318 it became common for researchers from other European medieval universities to visit Cambridge to study or to give lecture courses.

    Foundation of the colleges

    The colleges at the University of Cambridge were originally an incidental feature of the system. No college is as old as the university itself. The colleges were endowed fellowships of scholars. There were also institutions without endowments called hostels. The hostels were gradually absorbed by the colleges over the centuries; but they have left some traces, such as the name of Garret Hostel Lane.

    Hugh Balsham, Bishop of Ely, founded Peterhouse – Cambridge’s first college in 1284. Many colleges were founded during the 14th and 15th centuries but colleges continued to be established until modern times. There was a gap of 204 years between the founding of Sidney Sussex in 1596 and that of Downing in 1800. The most recently established college is Robinson built in the late 1970s. However Homerton College only achieved full university college status in March 2010 making it the newest full college (it was previously an “Approved Society” affiliated with the university).

    In medieval times many colleges were founded so that their members would pray for the souls of the founders and were often associated with chapels or abbeys. The colleges’ focus changed in 1536 with the Dissolution of the Monasteries. Henry VIII ordered the university to disband its Faculty of Canon Law and to stop teaching “scholastic philosophy”. In response, colleges changed their curricula away from canon law and towards the classics; the Bible; and mathematics.

    Nearly a century later the university was at the centre of a Protestant schism. Many nobles, intellectuals and even commoners saw the ways of the Church of England as too similar to the Catholic Church and felt that it was used by the Crown to usurp the rightful powers of the counties. East Anglia was the centre of what became the Puritan movement. In Cambridge the movement was particularly strong at Emmanuel; St Catharine’s Hall; Sidney Sussex; and Christ’s College. They produced many “non-conformist” graduates who, greatly influenced by social position or preaching left for New England and especially the Massachusetts Bay Colony during the Great Migration decade of the 1630s. Oliver Cromwell, Parliamentary commander during the English Civil War and head of the English Commonwealth (1649–1660), attended Sidney Sussex.

    Modern period

    After the Cambridge University Act formalised the organisational structure of the university the study of many new subjects was introduced e.g. theology, history and modern languages. Resources necessary for new courses in the arts architecture and archaeology were donated by Viscount Fitzwilliam of Trinity College who also founded the Fitzwilliam Museum. In 1847 Prince Albert was elected Chancellor of the University of Cambridge after a close contest with the Earl of Powis. Albert used his position as Chancellor to campaign successfully for reformed and more modern university curricula, expanding the subjects taught beyond the traditional mathematics and classics to include modern history and the natural sciences. Between 1896 and 1902 Downing College sold part of its land to build the Downing Site with new scientific laboratories for anatomy, genetics, and Earth sciences. During the same period the New Museums Site was erected including the Cavendish Laboratory which has since moved to the West Cambridge Site and other departments for chemistry and medicine.

    The University of Cambridge began to award PhD degrees in the first third of the 20th century. The first Cambridge PhD in mathematics was awarded in 1924.

    In the First World War 13,878 members of the university served and 2,470 were killed. Teaching and the fees it earned came almost to a stop and severe financial difficulties followed. As a consequence the university first received systematic state support in 1919 and a Royal Commission appointed in 1920 recommended that the university (but not the colleges) should receive an annual grant. Following the Second World War the university saw a rapid expansion of student numbers and available places; this was partly due to the success and popularity gained by many Cambridge scientists.

    A massive volcanic eruption in Indonesia about 74,000 years ago likely caused severe climate disruption in many areas of the globe, but early human populations were sheltered from the worst effects, suggests a new study published in the journal PNAS.

    The eruption of the Toba volcano was the largest volcanic eruption in the past two million years, but its impacts on climate and human evolution have been unclear. Resolving this debate is important for understanding environmental changes during a key interval in human evolution.

    “We were able to use a large number of climate model simulations to resolve what seemed like a paradox,” said lead author Benjamin Black from Rutgers University (US). “We know this eruption happened and that past climate modeling has suggested the climate consequences could have been severe, but archaeological and palaeoclimate records from Africa don’t show such a dramatic response.

    “Our results suggest that we might not have been looking in the right place to see the climate response. Africa and India are relatively sheltered, whereas North America Europe and Asia bear the brunt of the cooling. One intriguing aspect of this is that Neanderthals and Denisovans were living in Europe and Asia at this time, so our paper suggests evaluating the effects of the Toba eruption on those populations could merit future investigation.”

    The researchers analysed 42 global climate model simulations in which they varied magnitude of sulphur emissions, time of year of the eruption, background climate state and sulfur injection altitude to make a probabilistic assessment of the range of climate disruptions the Toba eruption may have caused.

    The results suggest there was likely significant regional variation in climate impacts. The simulations predict cooling in the Northern Hemisphere of at least 4°C, with regional cooling as high as 10°C depending on the model parameters.

    In contrast, even under the most severe eruption conditions, cooling in the Southern Hemisphere — including regions populated by early humans – was unlikely to exceed 4°C, although regions in southern Africa and India may have seen decreases in precipitation at the highest sulphur emission level.

    The results explain independent archaeological evidence suggesting the Toba eruption had modest effects on the development of hominid species in Africa. According to the authors, their ensemble simulation approach could be used to better understand other past and future explosive eruptions.

    “Our work is not only a forensic analysis of Toba’s aftermath some 74,000 years ago, but also a means of understanding the unevenness of the effects such very large eruptions may have on today’s society,” said co-author Dr Anja Schmidt from the University of Cambridge. “Ultimately, this will help to mitigate the environmental and societal hazards from future volcanic eruptions.”

    The study included researchers from the US National Center for Atmospheric Research, the University of Leeds (UK) and University of Cambridge in the UK, and was supported by the National Center for Atmospheric Research and the National Science Foundation (US).

    U Cambridge Campus

    The University of Cambridge (UK) [legally The Chancellor, Masters, and Scholars of the University of Cambridge] is a collegiate public research university in Cambridge, England. Founded in 1209 Cambridge is the second-oldest university in the English-speaking world and the world’s fourth-oldest surviving university. It grew out of an association of scholars who left the University of Oxford(UK) after a dispute with townsfolk. The two ancient universities share many common features and are often jointly referred to as “Oxbridge”.

    Cambridge is formed from a variety of institutions which include 31 semi-autonomous constituent colleges and over 150 academic departments, faculties and other institutions organised into six schools. All the colleges are self-governing institutions within the university, each controlling its own membership and with its own internal structure and activities. All students are members of a college. Cambridge does not have a main campus and its colleges and central facilities are scattered throughout the city. Undergraduate teaching at Cambridge is organised around weekly small-group supervisions in the colleges – a feature unique to the Oxbridge system. These are complemented by classes, lectures, seminars, laboratory work and occasionally further supervisions provided by the central university faculties and departments. Postgraduate teaching is provided predominantly centrally.

    Cambridge University Press a department of the university is the oldest university press in the world and currently the second largest university press in the world.

    Hundreds of millions of years ago, in the middle of what would eventually become Canada’s Yukon Territory, an ocean swirled with armored trilobites, clam-like brachiopods and soft, squishy creatures akin to slugs and squid.

    A trove of fossils and rock layers formed on that ancient ocean floor have now been unearthed by an international team of scientists along the banks of the Peel River a few hundred miles south of the Arctic’s Beaufort Sea. The discovery reveals oxygen changes at the seafloor across nearly 120 million years of the early Paleozoic era, a time that fostered the most rapid development and diversification of complex, multi-cellular life in Earth’s history.

    “It’s unheard of to have that much of Earth’s history in one place,” said Stanford University geological scientist Erik Sperling, lead author of a July 7 study detailing the team’s findings in Science Advances. Most rock formations from the Paleozoic Era have been broken up by tectonic forces or eroded over time. “There’s nowhere else in the world that I know of where you can study that long a record of Earth history, where there’s basically no change in things like water depth or basin type.”

    Oxygen was scarce in the deep water of this and other oceans at the dawn of the Paleozoic roughly 541 million years ago. It stayed scarce until the Devonian, roughly 405 million years ago, when, in a geological blink – no more than a few million years – oxygen likely rocketed to levels close to those in modern oceans and the diversity of life on Earth exploded. Big, predatory fish appeared. Primitive ferns and conifers marched across continents previously ruled by bacteria and algae. Dragonflies took flight. And all of this after nearly four billion years of Earth’s landscapes being virtually barren.

    Scientists have long debated what might have caused the dramatic shift from a low oxygen world to a more oxygenated one that could support a diverse web of animal life. But until now, it has been difficult to pin down the timing of global oxygenation or the long-term, background state of the world’s oceans and atmosphere during the era that witnessed both the so-called Cambrian explosion of life and the first of Earth’s “Big Five” mass extinctions, about 445 million years ago at the end of the Ordovician.

    “In order to make comparisons throughout these huge swaths of our history and understand long-term trends, you need a continuous record,” said Sperling, an assistant professor of geological sciences at Stanford’s School of Earth, Energy & Environmental Sciences (Stanford Earth).

    Context for past life

    With permission from the Na Cho Nyak Dun and Tetlit Gwitch’in communities in Yukon, Sperling’s team, which included researchers from Dartmouth College (US) and the Yukon Geological Survey, spent three summers at the Peel River site. Arriving by helicopter, the research team hacked through brush with machetes beside Class VI rapids to collect hundreds of fist-sized samples of rock from more than a mile of interbedded layers of shale, chert and lime mudstone.

    Back at Sperling’s lab at Stanford, a small army of summer undergraduates and graduate students worked over five summers to help analyze the fossils and chemicals entombed in the rocks. “We spent a lot of time splitting open rocks and looking at graptolite fossils,” Sperling said. Because graptolites evolved a vast array of recognizable body shapes relatively quickly, the pencil-like markings left by the fossils of these colony-dwelling sea creatures give geologists a way to date the rocks in which they’re found.

    Once the researchers had finished identifying and dating graptolite fossils, they ground the rocks in a mill, then measured iron, carbon, phosphorous and other elements in the resulting powder to assess the ocean conditions at the time and place where the layers formed. They analyzed 837 new samples from the Peel River site, as well as 106 new samples from other parts of Canada and 178 samples from around the world for comparison.

    Stephanie Plaza-Torres, a co-author on the study who analyzed several dozen samples for the project in 2016 as an undergraduate in Stanford’s Summer Undergraduate Research in Geoscience and Engineering Program (SURGE), has gone on to pursue a PhD student in geological sciences at the University of Colorado-Boulder (US). “The most intriguing part for me was learning about geochemistry and how it is so useful for figuring out the environmental backdrop of ancient times. It really gives you the whole context for past life,” Plaza-Torres said. “After SURGE, I was hooked on geochemistry.”

    Winners and losers

    The data show low oxygen levels, or anoxia, likely persisted in the world’s oceans for millions of years longer than previously thought – well into the Phanerozoic, when land plants and early animals began to diversify. “The early animals were still living in a low oxygen world,” Sperling said. Contrary to long-held assumptions, the scientists found Paleozoic oceans were also surprisingly free of hydrogen sulfide, a respiratory toxin often found in the anoxic regions of modern oceans.

    When oxygen eventually did tick upward in marine environments it came about just as larger more complex plant life took off. “There’s a ton of debate about how plants impacted the Earth system,” Sperling said. “Our results are consistent with a hypothesis that as plants evolved and covered the Earth, they increased nutrients to the ocean, driving oxygenation.” In this hypothesis, the influx of nutrients to the sea would have given a boost to primary productivity, a measure of how quickly plants and algae take carbon dioxide and sunlight, turn them into new biomass – and release oxygen in the process.

    The change probably killed off graptolites. “Although more oxygen is really good for a lot of organisms, graptolites lost the low oxygen habitat that was their refuge,” Sperling said. “Any environmental change is going to have winners and losers. Graptolites might have been the losers.”

    Stanford University (US)

    Leland and Jane Stanford founded the University to “promote the public welfare by exercising an influence on behalf of humanity and civilization.” Stanford opened its doors in 1891, and more than a century later, it remains dedicated to finding solutions to the great challenges of the day and to preparing our students for leadership in today’s complex world. Stanford, is an American private research university located in Stanford, California on an 8,180-acre (3,310 ha) campus near Palo Alto. Since 1952, more than 54 Stanford faculty, staff, and alumni have won the Nobel Prize, including 19 current faculty members.

    Stanford University, officially Leland Stanford Junior University, is a private research university located in Stanford, California. Stanford was founded in 1885 by Leland and Jane Stanford in memory of their only child, Leland Stanford Jr., who had died of typhoid fever at age 15 the previous year. Stanford is consistently ranked as among the most prestigious and top universities in the world by major education publications. It is also one of the top fundraising institutions in the country, becoming the first school to raise more than a billion dollars in a year.

    Leland Stanford was a U.S. senator and former governor of California who made his fortune as a railroad tycoon. The school admitted its first students on October 1, 1891, as a coeducational and non-denominational institution. Stanford University struggled financially after the death of Leland Stanford in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, provost Frederick Terman supported faculty and graduates’ entrepreneurialism to build self-sufficient local industry in what would later be known as Silicon Valley.

    The university is organized around seven schools: three schools consisting of 40 academic departments at the undergraduate level as well as four professional schools that focus on graduate programs in law, medicine, education, and business. All schools are on the same campus. Students compete in 36 varsity sports, and the university is one of two private institutions in the Division I FBS Pac-12 Conference. It has gained 126 NCAA team championships, and Stanford has won the NACDA Directors’ Cup for 24 consecutive years, beginning in 1994–1995. In addition, Stanford students and alumni have won 270 Olympic medals including 139 gold medals.

    As of October 2020, 84 Nobel laureates, 28 Turing Award laureates, and eight Fields Medalists have been affiliated with Stanford as students, alumni, faculty, or staff. In addition, Stanford is particularly noted for its entrepreneurship and is one of the most successful universities in attracting funding for start-ups. Stanford alumni have founded numerous companies, which combined produce more than $2.7 trillion in annual revenue, roughly equivalent to the 7th largest economy in the world (as of 2020). Stanford is the alma mater of one president of the United States (Herbert Hoover), 74 living billionaires, and 17 astronauts. It is also one of the leading producers of Fulbright Scholars, Marshall Scholars, Rhodes Scholars, and members of the United States Congress.

    Stanford University was founded in 1885 by Leland and Jane Stanford, dedicated to Leland Stanford Jr, their only child. The institution opened in 1891 on Stanford’s previous Palo Alto farm.

    Jane and Leland Stanford modeled their university after the great eastern universities, most specifically Cornell University. Stanford opened being called the “Cornell of the West” in 1891 due to faculty being former Cornell affiliates (either professors, alumni, or both) including its first president, David Starr Jordan, and second president, John Casper Branner. Both Cornell and Stanford were among the first to have higher education be accessible, nonsectarian, and open to women as well as to men. Cornell is credited as one of the first American universities to adopt this radical departure from traditional education, and Stanford became an early adopter as well.

    Despite being impacted by earthquakes in both 1906 and 1989, the campus was rebuilt each time. In 1919, The Hoover Institution on War, Revolution and Peace was started by Herbert Hoover to preserve artifacts related to World War I. The Stanford Medical Center, completed in 1959, is a teaching hospital with over 800 beds. The DOE’s SLAC National Accelerator Laboratory(US)(originally named the Stanford Linear Accelerator Center), established in 1962, performs research in particle physics.

    Land

    Most of Stanford is on an 8,180-acre (12.8 sq mi; 33.1 km^2) campus, one of the largest in the United States. It is located on the San Francisco Peninsula, in the northwest part of the Santa Clara Valley (Silicon Valley) approximately 37 miles (60 km) southeast of San Francisco and approximately 20 miles (30 km) northwest of San Jose. In 2008, 60% of this land remained undeveloped.

    Stanford’s main campus includes a census-designated place within unincorporated Santa Clara County, although some of the university land (such as the Stanford Shopping Center and the Stanford Research Park) is within the city limits of Palo Alto. The campus also includes much land in unincorporated San Mateo County (including the SLAC National Accelerator Laboratory and the Jasper Ridge Biological Preserve), as well as in the city limits of Menlo Park (Stanford Hills neighborhood), Woodside, and Portola Valley.

    Non-central campus

    Stanford currently operates in various locations outside of its central campus.

    On the founding grant:

    Jasper Ridge Biological Preserve is a 1,200-acre (490 ha) natural reserve south of the central campus owned by the university and used by wildlife biologists for research.
    SLAC National Accelerator Laboratory is a facility west of the central campus operated by the university for the Department of Energy. It contains the longest linear particle accelerator in the world, 2 miles (3.2 km) on 426 acres (172 ha) of land.
    Golf course and a seasonal lake: The university also has its own golf course and a seasonal lake (Lake Lagunita, actually an irrigation reservoir), both home to the vulnerable California tiger salamander. As of 2012 Lake Lagunita was often dry and the university had no plans to artificially fill it.

    Off the founding grant:

    Hopkins Marine Station, in Pacific Grove, California, is a marine biology research center owned by the university since 1892.
    Study abroad locations: unlike typical study abroad programs, Stanford itself operates in several locations around the world; thus, each location has Stanford faculty-in-residence and staff in addition to students, creating a “mini-Stanford”.

    Redwood City campus for many of the university’s administrative offices located in Redwood City, California, a few miles north of the main campus. In 2005, the university purchased a small, 35-acre (14 ha) campus in Midpoint Technology Park intended for staff offices; development was delayed by The Great Recession. In 2015 the university announced a development plan and the Redwood City campus opened in March 2019.

    The Bass Center in Washington, DC provides a base, including housing, for the Stanford in Washington program for undergraduates. It includes a small art gallery open to the public.

    China: Stanford Center at Peking University, housed in the Lee Jung Sen Building, is a small center for researchers and students in collaboration with Beijing University [北京大学](CN) (Kavli Institute for Astronomy and Astrophysics at Peking University(CN) (KIAA-PKU).

    Administration and organization

    Stanford is a private, non-profit university that is administered as a corporate trust governed by a privately appointed board of trustees with a maximum membership of 38. Trustees serve five-year terms (not more than two consecutive terms) and meet five times annually.[83] A new trustee is chosen by the current trustees by ballot. The Stanford trustees also oversee the Stanford Research Park, the Stanford Shopping Center, the Cantor Center for Visual Arts, Stanford University Medical Center, and many associated medical facilities (including the Lucile Packard Children’s Hospital).

    The board appoints a president to serve as the chief executive officer of the university, to prescribe the duties of professors and course of study, to manage financial and business affairs, and to appoint nine vice presidents. The provost is the chief academic and budget officer, to whom the deans of each of the seven schools report. Persis Drell became the 13th provost in February 2017.

    As of 2018, the university was organized into seven academic schools. The schools of Humanities and Sciences (27 departments), Engineering (nine departments), and Earth, Energy & Environmental Sciences (four departments) have both graduate and undergraduate programs while the Schools of Law, Medicine, Education and Business have graduate programs only. The powers and authority of the faculty are vested in the Academic Council, which is made up of tenure and non-tenure line faculty, research faculty, senior fellows in some policy centers and institutes, the president of the university, and some other academic administrators, but most matters are handled by the Faculty Senate, made up of 55 elected representatives of the faculty.

    The Associated Students of Stanford University (ASSU) is the student government for Stanford and all registered students are members. Its elected leadership consists of the Undergraduate Senate elected by the undergraduate students, the Graduate Student Council elected by the graduate students, and the President and Vice President elected as a ticket by the entire student body.

    Stanford is the beneficiary of a special clause in the California Constitution, which explicitly exempts Stanford property from taxation so long as the property is used for educational purposes.

    Endowment and donations

    The university’s endowment, managed by the Stanford Management Company, was valued at $27.7 billion as of August 31, 2019. Payouts from the Stanford endowment covered approximately 21.8% of university expenses in the 2019 fiscal year. In the 2018 NACUBO-TIAA survey of colleges and universities in the United States and Canada, only Harvard University(US), the University of Texas System(US), and Yale University(US) had larger endowments than Stanford.

    In 2006, President John L. Hennessy launched a five-year campaign called the Stanford Challenge, which reached its $4.3 billion fundraising goal in 2009, two years ahead of time, but continued fundraising for the duration of the campaign. It concluded on December 31, 2011, having raised a total of $6.23 billion and breaking the previous campaign fundraising record of $3.88 billion held by Yale. Specifically, the campaign raised $253.7 million for undergraduate financial aid, as well as $2.33 billion for its initiative in “Seeking Solutions” to global problems, $1.61 billion for “Educating Leaders” by improving K-12 education, and $2.11 billion for “Foundation of Excellence” aimed at providing academic support for Stanford students and faculty. Funds supported 366 new fellowships for graduate students, 139 new endowed chairs for faculty, and 38 new or renovated buildings. The new funding also enabled the construction of a facility for stem cell research; a new campus for the business school; an expansion of the law school; a new Engineering Quad; a new art and art history building; an on-campus concert hall; a new art museum; and a planned expansion of the medical school, among other things. In 2012, the university raised $1.035 billion, becoming the first school to raise more than a billion dollars in a year.

    Discoveries and innovation

    Natural sciences

    Biological synthesis of deoxyribonucleic acid (DNA) – Arthur Kornberg synthesized DNA material and won the Nobel Prize in Physiology or Medicine 1959 for his work at Stanford.
    First Transgenic organism – Stanley Cohen and Herbert Boyer were the first scientists to transplant genes from one living organism to another, a fundamental discovery for genetic engineering. Thousands of products have been developed on the basis of their work, including human growth hormone and hepatitis B vaccine.
    Laser – Arthur Leonard Schawlow shared the 1981 Nobel Prize in Physics with Nicolaas Bloembergen and Kai Siegbahn for his work on lasers.
    Nuclear magnetic resonance – Felix Bloch developed new methods for nuclear magnetic precision measurements, which are the underlying principles of the MRI.

    Computer and applied sciences

    ARPANETStanford Research Institute, formerly part of Stanford but on a separate campus, was the site of one of the four original ARPANET nodes.

    Internet—Stanford was the site where the original design of the Internet was undertaken. Vint Cerf led a research group to elaborate the design of the Transmission Control Protocol (TCP/IP) that he originally co-created with Robert E. Kahn (Bob Kahn) in 1973 and which formed the basis for the architecture of the Internet.

    Frequency modulation synthesis – John Chowning of the Music department invented the FM music synthesis algorithm in 1967, and Stanford later licensed it to Yamaha Corporation.

    Google – Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford. They were working on the Stanford Digital Library Project (SDLP). The SDLP’s goal was “to develop the enabling technologies for a single, integrated and universal digital library” and it was funded through the National Science Foundation, among other federal agencies.

    Klystron tube – invented by the brothers Russell and Sigurd Varian at Stanford. Their prototype was completed and demonstrated successfully on August 30, 1937. Upon publication in 1939, news of the klystron immediately influenced the work of U.S. and UK researchers working on radar equipment.

    RISCARPA funded VLSI project of microprocessor design. Stanford and UC Berkeley are most associated with the popularization of this concept. The Stanford MIPS would go on to be commercialized as the successful MIPS architecture, while Berkeley RISC gave its name to the entire concept, commercialized as the SPARC. Another success from this era were IBM’s efforts that eventually led to the IBM POWER instruction set architecture, PowerPC, and Power ISA. As these projects matured, a wide variety of similar designs flourished in the late 1980s and especially the early 1990s, representing a major force in the Unix workstation market as well as embedded processors in laser printers, routers and similar products.
    SUN workstation – Andy Bechtolsheim designed the SUN workstation for the Stanford University Network communications project as a personal CAD workstation, which led to Sun Microsystems.

    Businesses and entrepreneurship

    Stanford is one of the most successful universities in creating companies and licensing its inventions to existing companies; it is often held up as a model for technology transfer. Stanford’s Office of Technology Licensing is responsible for commercializing university research, intellectual property, and university-developed projects.

    The university is described as having a strong venture culture in which students are encouraged, and often funded, to launch their own companies.

    Companies founded by Stanford alumni generate more than $2.7 trillion in annual revenue, equivalent to the 10th-largest economy in the world.

    Some companies closely associated with Stanford and their connections include:

    Hewlett-Packard, 1939, co-founders William R. Hewlett (B.S, PhD) and David Packard (M.S).
    Silicon Graphics, 1981, co-founders James H. Clark (Associate Professor) and several of his grad students.
    Sun Microsystems, 1982, co-founders Vinod Khosla (M.B.A), Andy Bechtolsheim (PhD) and Scott McNealy (M.B.A).
    Cisco, 1984, founders Leonard Bosack (M.S) and Sandy Lerner (M.S) who were in charge of Stanford Computer Science and Graduate School of Business computer operations groups respectively when the hardware was developed.[163]
    Yahoo!, 1994, co-founders Jerry Yang (B.S, M.S) and David Filo (M.S).
    Google, 1998, co-founders Larry Page (M.S) and Sergey Brin (M.S).
    LinkedIn, 2002, co-founders Reid Hoffman (B.S), Konstantin Guericke (B.S, M.S), Eric Lee (B.S), and Alan Liu (B.S).
    Instagram, 2010, co-founders Kevin Systrom (B.S) and Mike Krieger (B.S).
    Snapchat, 2011, co-founders Evan Spiegel and Bobby Murphy (B.S).
    Coursera, 2012, co-founders Andrew Ng (Associate Professor) and Daphne Koller (Professor, PhD).

    Student body

    Stanford enrolled 6,996 undergraduate and 10,253 graduate students as of the 2019–2020 school year. Women comprised 50.4% of undergraduates and 41.5% of graduate students. In the same academic year, the freshman retention rate was 99%.

    Stanford awarded 1,819 undergraduate degrees, 2,393 master’s degrees, 770 doctoral degrees, and 3270 professional degrees in the 2018–2019 school year. The four-year graduation rate for the class of 2017 cohort was 72.9%, and the six-year rate was 94.4%. The relatively low four-year graduation rate is a function of the university’s coterminal degree (or “coterm”) program, which allows students to earn a master’s degree as a 1-to-2-year extension of their undergraduate program.

    As of 2010, fifteen percent of undergraduates were first-generation students.

    Athletics

    As of 2016 Stanford had 16 male varsity sports and 20 female varsity sports, 19 club sports and about 27 intramural sports. In 1930, following a unanimous vote by the Executive Committee for the Associated Students, the athletic department adopted the mascot “Indian.” The Indian symbol and name were dropped by President Richard Lyman in 1972, after objections from Native American students and a vote by the student senate. The sports teams are now officially referred to as the “Stanford Cardinal,” referring to the deep red color, not the cardinal bird. Stanford is a member of the Pac-12 Conference in most sports, the Mountain Pacific Sports Federation in several other sports, and the America East Conference in field hockey with the participation in the inter-collegiate NCAA’s Division I FBS.

    Its traditional sports rival is the University of California, Berkeley, the neighbor to the north in the East Bay. The winner of the annual “Big Game” between the Cal and Cardinal football teams gains custody of the Stanford Axe.

    Stanford has had at least one NCAA team champion every year since the 1976–77 school year and has earned 126 NCAA national team titles since its establishment, the most among universities, and Stanford has won 522 individual national championships, the most by any university. Stanford has won the award for the top-ranked Division 1 athletic program—the NACDA Directors’ Cup, formerly known as the Sears Cup—annually for the past twenty-four straight years. Stanford athletes have won medals in every Olympic Games since 1912, winning 270 Olympic medals total, 139 of them gold. In the 2008 Summer Olympics, and 2016 Summer Olympics, Stanford won more Olympic medals than any other university in the United States. Stanford athletes won 16 medals at the 2012 Summer Olympics (12 gold, two silver and two bronze), and 27 medals at the 2016 Summer Olympics.

    Traditions

    The unofficial motto of Stanford, selected by President Jordan, is Die Luft der Freiheit weht. Translated from the German language, this quotation from Ulrich von Hutten means, “The wind of freedom blows.” The motto was controversial during World War I, when anything in German was suspect; at that time the university disavowed that this motto was official.
    Hail, Stanford, Hail! is the Stanford Hymn sometimes sung at ceremonies or adapted by the various University singing groups. It was written in 1892 by mechanical engineering professor Albert W. Smith and his wife, Mary Roberts Smith (in 1896 she earned the first Stanford doctorate in Economics and later became associate professor of Sociology), but was not officially adopted until after a performance on campus in March 1902 by the Mormon Tabernacle Choir.
    “Uncommon Man/Uncommon Woman”: Stanford does not award honorary degrees, but in 1953 the degree of “Uncommon Man/Uncommon Woman” was created to recognize individuals who give rare and extraordinary service to the University. Technically, this degree is awarded by the Stanford Associates, a voluntary group that is part of the university’s alumni association. As Stanford’s highest honor, it is not conferred at prescribed intervals, but only when appropriate to recognize extraordinary service. Recipients include Herbert Hoover, Bill Hewlett, Dave Packard, Lucile Packard, and John Gardner.
    Big Game events: The events in the week leading up to the Big Game vs. UC Berkeley, including Gaieties (a musical written, composed, produced, and performed by the students of Ram’s Head Theatrical Society).
    “Viennese Ball”: a formal ball with waltzes that was initially started in the 1970s by students returning from the now-closed Stanford in Vienna overseas program. It is now open to all students.
    “Full Moon on the Quad”: An annual event at Main Quad, where students gather to kiss one another starting at midnight. Typically organized by the Junior class cabinet, the festivities include live entertainment, such as music and dance performances.
    “Band Run”: An annual festivity at the beginning of the school year, where the band picks up freshmen from dorms across campus while stopping to perform at each location, culminating in a finale performance at Main Quad.
    “Mausoleum Party”: An annual Halloween Party at the Stanford Mausoleum, the final resting place of Leland Stanford Jr. and his parents. A 20-year tradition, the “Mausoleum Party” was on hiatus from 2002 to 2005 due to a lack of funding, but was revived in 2006. In 2008, it was hosted in Old Union rather than at the actual Mausoleum, because rain prohibited generators from being rented. In 2009, after fundraising efforts by the Junior Class Presidents and the ASSU Executive, the event was able to return to the Mausoleum despite facing budget cuts earlier in the year.
    Former campus traditions include the “Big Game bonfire” on Lake Lagunita (a seasonal lake usually dry in the fall), which was formally ended in 1997 because of the presence of endangered salamanders in the lake bed.
