    2.1 billion people still don’t have safe drinking water.

    Using a type of graphene called Graphair, scientists from Australia have created a water filter that can make highly polluted seawater drinkable after just one pass.

    The technology could be used to cheaply provide safe drinking water to regions of the world without access to it.

    “Almost a third of the world’s population, some 2.1 billion people, don’t have clean and safe drinking water,” said lead author Dong Han Seo.

    “As a result, millions – mostly children – die from diseases associated with inadequate water supply, sanitation and hygiene every year. In Graphair we’ve found a perfect filter for water purification.

    “It can replace the complex, time consuming and multi-stage processes currently needed with a single step.”

    Developed by researchers at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Graphair is a form of graphene made out of soybean oil.

    Graphene – a one-atom-thick, ultrastrong carbon material – might be touted as a supermaterial, but it’s been relatively expensive to produce, which has been limiting its use in broader applications.

    Graphair is cheaper and simpler to produce than more traditional graphene manufacturing methods, while retaining the properties of graphene.

    One of those properties is hydrophobia – graphene repels water.

    To turn it into a filter, the researchers developed a graphene film with microscopic nanochannels; these allow the water through, but stop larger pollutants with larger molecules.

    Then the team overlaid their new film on a typical, commercial-grade water filtration membrane to do some tests.

    When used by itself, a water filtration membrane becomes coated with contaminants, blocking the pores that allow the water through. The researchers found that during their tests using highly polluted Sydney Harbour water, a normal water filter’s filtration rate halved without the graphene film.

    Then the Graphair was added to the filter. The team found that the combination filter screened out more contaminants – 99 percent of them – faster than the conventional filter. And it continued to work even when coated with pollutants, the researchers said.

    This eliminates a step from other filtration methods – removing the contaminants from the water before passing it through the membrane to prevent them from coating it.

    This is a similar result to one found last year, where minuscule pores in a graphene filter were able to prevent salt from seawater from passing through – and allow water through faster.

    “This technology can create clean drinking water, regardless of how dirty it is, in a single step,” Seo said.

    “All that’s needed is heat, our graphene, a membrane filter, and a small water pump. We’re hoping to commence field trials in a developing world community next year.”

    Eventually, they believe that the technology could be used for household and even town-based water filtration, as well as seawater and industrial wastewater treatment.

    For the first time scientists will deploy new model deep sea Argo floats in the Southern Ocean that will help build our understanding of oceans, how they are warming and the impact on our climate.

    A global network of over 3800 Argo floats already provide us with an understanding of ocean temperature and salinity up to 2000 metres, however these new generation, data-collecting, autonomous ocean robots will provide unprecedented information about oceans up to depths of 5000 metres.

    The deep water Argo floats will be deployed as part of a six-week research expedition that will set sail for Antarctica tomorrow aboard CSIRO’s Research Vessel “Investigator”.

    Researchers will be investigating climate contributions of the deep ocean, clouds and atmospheric aerosols through a series of projects that will fill information gaps about the magnitude and pace of future climate change.

    Voyage Chief Scientist Dr Steve Rintoul, from CSIRO and the Antarctic Climate and Ecosystems CRC, said research from the voyage would provide unique information about the Southern Hemisphere’s ocean’s capacity to continue to absorb heat and carbon dioxide.

    “The world’s climate is strongly influenced by the oceans, and the vast Southern Ocean plays a major role in how climate variability and change will play out in future decades,” Dr Rintoul said.

    “We already know that the Southern Ocean makes important contributions to global sea level change through taking up more heat than any other ocean on Earth and through influencing how fast the Antarctic Ice Sheet loses mass.

    “To understand this system we need comprehensive and continuous measurements over a huge area of ocean, which has been very difficult in the past.”

    Dr Rintoul’s team will be deploying 11 deep-water floats near the Antarctic edge that have been supplied by the Scripps Research Institute (USA), Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and Laboratoire d’Océanographie et du Climat (LOCEAN, France).

    “It’s the first time these next-generation deep water Argo floats will be deployed near Antarctica. By providing year-round measurements through the full ocean depth, the floats will fill a massive data gap for the climate research community,” Dr Rintoul said.

    Scientists from the Antarctic Climate and Ecosystems Cooperative Research Centre will also be making measurements of trace elements like iron, using ultra-clean techniques to avoid contamination. Phytoplankton, like humans, need small amounts of iron to be healthy. The voyage will help identify what controls how much biological activity occurs in the Southern Ocean.

    During the Investigator’s journey, an international team of scientists from agencies including CSIRO, the Australian Bureau of Meteorology, the US National Centre for Atmospheric Research (NCAR), and the University of Utah, will conduct experiments to explore the interaction between aerosols and clouds.

    Clouds and aerosols, which occur naturally and from greenhouse gases, both reflect and absorb heat from the sun, but as greenhouse gases change globally, so will this interaction.

    Bureau of Meteorology Project Leader Dr Alain Protat said that the experiments will use a unique combination of aircraft, ship-based and satellite observations to collect detailed data on clouds and the interactions between incoming radiation, aerosol production, and then the formation of precipitation.

    “The Southern Ocean region is the cloudiest place on Earth, yet we don’t understand why these clouds are different from clouds in other regions – the lack of pollution over this remote region is a possible explanation, which we will explore with these unprecedented observations,” Dr Protat said.

    “We know from reference satellite observations that global climate models struggle to represent the energy balance at the Earth’s surface over the Southern Ocean region, and what that means for the accuracy of future climate predictions is largely unknown.

    “The complexity of the problem requires collocated, state-of-the art, measurements of aerosol, clouds, precipitation and radiation to understand the interactions and feedbacks between them.”

    Ocean and atmospheric research conducted aboard the Investigator will provide valuable and unique insights to inform knowledge of climate change and sea level rise projections.

    The Investigator is run by the Marine National Facility and is Australia’s only blue-water research vessel, enabling scientists from across Australia and the world to study from the equator to Antarctica.

    From CSIRO: “Ten innovations chosen for Accelerator program”

    A detection system to keep prawns safe from pests, a smarter smaller wind turbine and wearable tech that can screen for gut disorders are some of the emerging technologies that will be fast-tracked though the national sci-tech accelerator, ‘ON, powered by CSIRO’.

    Ten teams announced today have been selected for the latest round of ON Accelerate, a structured, full-time accelerator that brings together the experience and expertise of established researchers, entrepreneurs and inspiring mentors.

    [I found no image of the accelerator.]

    CSIRO Chief Executive Dr Larry Marshall said that ON had uncovered science and technology solutions for some of Australia’s biggest challenges in energy, food and agriculture, water quality, wildlife conservation and health.

    “Establishing ON was about bringing the Australian research sector closer to Australian industry – creating a pathway to help our scientists turn their excellent science into real-world solutions,” Dr Marshall said.

    “The program is built on the shoulders of scientists who have made the leap into business, and likewise business people who have leapt into the world of science.

    “Bridging the gap between science and business, ON delivers in a similar way to the prestigious US I-Corps program, which is probably the most successful accelerator in the world.

    “The key advantage of ON is that it is backed by the national science agency, and almost every university has jumped in with us to support ON.

    “This collaboration across the innovation system is allowing us to deliver game-changing innovations for Australia and the world.”

    Selected following a competitive two-day bootcamp, the teams come from the University of Newcastle, Flinders University, Macquarie University, The University of Western Australia, James Cook University and CSIRO.

    Tony Tucker from the ‘eDNA Field Pump’ team at James Cook University in Townsville said ON had completely changed his view on commercialisation and the value in unlocking important Australian research.

    “When we came into Bootcamp, I was initially sceptical about what we could get out of the program, and wasn’t sure what we could actually achieve,” Mr Tucker said.

    “But I’m completely won over by the ON program – I now know why this experience is so important.

    “The feedback from the mentors and judging panel helped me see how we could have an even greater impact.

    “We weren’t thinking big enough. Now I know we can push our technology to even more applications for the world.”

    In the 18 months since CSIRO opened the ON accelerator to universities and publicly funded research agencies under the National Innovation and Science Agenda (NISA), it has graduated 200 teams of researchers with the business and entrepreneurial skills needed to fast-track great science and technology innovation from the lab to reality.

    The 10 big ideas to be fast-tracked through this round of ON Accelerate include:

    Virtual reality technology that allows carers to learn by doing, safely – The University of Newcastle
    A tool for preventing faults in power network assets before energy catastrophes hit – Curtin University
    A solar forecasting system – CSIRO, Energy
    An acoustic belt that uses the natural noises of the gut for health screening – The University of Western Australia
    An on-the-go field tool for reliable and transportable water monitoring – James Cook University
    A new pest detection system that cuts costs and time delays for Aussie prawn farmers – CSIRO Agriculture and Food
    An alternative to the expensive and cumbersome ‘leaky gut’ test for suspected sufferers – CSIRO Health and Biosecurity
    A new way to beat the current costs and delays in new drug development – Macquarie University
    On the spot testing for elite athletes and their sport scientists – The University of Western Australia
    A small wind turbine that can produce nearly twice the power than existing wind turbines of the same size – The University of Newcastle

    The 10 successful teams were chosen by ON’s industry mentor network and an expert judging panel of Liddy McCall co-founder of Yuuwa Capital, COO of Performance Assurance Ruth Marshall and Martin Duursma from CSIRO’s Main Sequence Ventures.

    These teams join successful graduates of the ON accelerator like Cardihab, Coivu, Modular Photonics, Silentium Defence and ePat.

    ON Accelerate4 will commence in February 2018 and will run for twelve weeks in hubs across the country, where teams will develop business planning, commercialisation and pitching skills.

    The program culminates in ‘ON Demo Night’ where teams will pitch their innovations to an audience of industry experts, investors and potential partners for further funding and support for commercialisation.

    Australia seems on the brink of embracing space in a coordinated manner, but how should we do it?

    This week, the Australian government released three reports to help chart the future of Australia’s space industry. Their conclusions will feed into the review of Australia’s space industry underway by former CSIRO head Dr Megan Clark.

    The reports examine Australia’s existing space capabilities, set them in the light of international developments, and identify growth areas and models for Australia to pursue. The promise is there:

    Australia has scattered globally competitive capabilities in areas from space weather to deep-space communication but “by far the strongest areas” are applications of satellite data on Earth to industries like agriculture, communications and mining
    Australian research in other sectors like 3D printing and VR is being translated to space with potentially high payoffs
    global trends, including the demand for more space traffic management, play to our emerging strengths
    the prize for success is real – the UK currently has an A$8 billion space export industry, and anticipates further growth.

    While it is not the first time the government has commissioned this type of research, the updates are welcome given the fast pace of space innovation. Taken together they paint a picture of potential for the future of Australian space and a firm foundation for a space agency.

    The rules of the game

    The Global Space Industry Dynamics report from Bryce Space and Technology, a US-based space specialist consulting firm, sets out the “rules of the game” in the US$344 billion (A$450 billion) space sector.

    2
    The global space economy at a glance. Figures are from 2016, and shown in US$.
    Marcella Cheng for The Conversation, adapted from Global Space Industry Dynamics Research Paper by Bryce Space and Technology

    It highlights that:

    three quarters of global revenues are made commercially, despite the prevailing perception that space is a government concern
    most commercial revenue is made from space-enabled services and applications (like satellite TV or GPS receivers) rather than the construction and launch of space hardware itself
    commercial launch and satellite manufacturing industries are still small in relative terms, at about US$20.5 billion (A$27 billion) of revenues, but show strong growth, particularly for smaller satellites and launch vehicles.

    The report also looks at the emerging trends that a smart space industry in Australia will try and run ahead of. Space is becoming cheaper, more attractive to investors and increasingly important in our data-rich economy. These trends have not gone unnoticed by global competitors, though, and the report describes space as an increasingly “crowded and valuable high ground”.

    What is particularly useful about the report is its sharp focus on the three numbers that determine commercial attractiveness:

    market size
    growth
    profitability.

    The magic comes through matching these attractive sectors against areas where Australia can compete strongly because of existing capability or geographic advantage.

    The report suggests growth opportunities across traditional and emerging space sectors. In traditional sectors, it calls out satellite services, particularly commercial satellite radio and broadband, and ground infrastructure as prime opportunities. In emerging sectors, earth observation data analytics, space traffic management, and small satellite manufacturing are all tipped as potentially profitable growth areas where Australia could compete.

    The report adds the speculative area of space mining as an additional sector worth considering given Australia’s existing terrestrial capability.

    It is encouraging that Australian organisations have anticipated the growth areas, from UNSW’s off-earth mining research, to Geoscience Australia’s integrated satellite data to Mt Stromlo’s debris tracking capability.

    Australian capabilities

    Australian capabilities are the focus of a second report, by ACIL Allen consulting, Australian Space Industry Capability. The review highlights a smattering of world class Australian capabilities, particularly in the application of space data to activities on Earth like agriculture, transport and financial services.

    There are also emerging Australian capabilities in small satellites and potentially disruptive technologies with space applications, like 3D printing, AI and quantum computing. The report notes that basic research is strong, but challenges remain in “industrialising and commercialising the resulting products”.


    Australian universities made cubesats for an international research project.

    The concern about commercialisation prompts questions about the policies that will help Australian companies succeed.

    Should we embrace recent trends and rely wholly on market mechanisms and venture capital Darwinism, or buy into traditional international space projects?

    Do we send our brightest overseas for a few years’ training, or spin up a full suite of research and development programs domestically?

    Are there regulations that need to change to level the playing field for Australian space exports?
    Learning from the world

    Part of the answer is to be found in the third report, Global Space Strategies and Best Practices, which looks at global approaches to funding, capability development, and governance arrangements. The case studies illustrate a range of styles.

    The UK’s pragmatic approach developed a £5 billion (A$8 billion) export industry by focusing primarily on competitive commercial applications, including a satellite Australia recently bought a time-share on.

    A longer-term play is Luxembourg’s use of tax breaks and legal changes to attract space mining ventures. Before laughing, remember that Luxembourg has space clout: satellite giants SES and Intelsat are headquartered there thanks to similar forward thinking in the 1980s. Those two companies pulled in about A$3 billion of profit between them last year.

    Norway and Canada show a middle ground, combining international partnerships with clear focus areas that benefit research and the economy. Norway has taken advantage of its geography to build satellite ground stations for polar-orbiting satellites, in an interesting parallel with Australia’s longstanding ground capabilities. Canada used its relationship with the United States to build the robotic “Canadarm” for the Space Shuttle and International Space Station, developing a space robotics capability for the country.


    Canadarm played an important role in Canada-USA relations.

    The only caution is that confining the possible role models to the space sector is unnecessarily limiting. Commercialisation in technology fields is a broader policy question, and there is much to learn from recent innovations including CSIRO’s venture fund and the broader Cooperative Research Centre (CRC) program.

    As well as the three reports, the government recently released 140 public submissions to the panel.

    There is no shortage of advice for Dr Clark and the expert reference group; appropriate given it seems an industry of remarkable potential rests in their hands.

    CSIRO Parkes radio telescope has discovered around half of all known pulsars. Wayne England, Author provided.

    A pulsar is a small, spinning star – a giant ball of neutrons, left behind after a normal star has died in a fiery explosion.

    With a diameter of only 30 km, the star spins up to hundreds of times a second, while sending out a beam of radio waves (and sometimes other radiation, such as X-rays). When the beam is pointed in our direction and into our telescopes, we see a pulse.

    2017 marks 50 years since pulsars were discovered. In that time, we have found more than 2,600 pulsars (mostly in the Milky Way), and used them to hunt for low-frequency gravitational waves, to determine the structure of our galaxy and to test the general theory of relativity.

    The Discovery

    In mid-1967, when thousands of people were enjoying the summer of love, a young PhD student at the University of Cambridge in the UK was helping to build a telescope.

    It was a poles-and-wires affair – what astronomers call a “dipole array”. It covered a bit less than two hectares, the area of 57 tennis courts.

    2
    Jocelyn Bell Burnell, who discovered the first pulsar. CC BY-SA

    By July it was built. The student, Jocelyn Bell (now Dame Jocelyn Bell Burnell), became responsible for running it and analysing the data it churned out. The data came in the form of pen-on-paper chart records, more than 30 metres of them each day. Bell analysed them by eye.

    What she found – a little bit of “scruff” on the chart records – has gone down in history.

    Like most discoveries, it took place over time. But there was a turning point. On November 28, 1967, Bell and her supervisor, Antony Hewish, were able to capture a “fast recording” – that is, a detailed one – of one of the strange signals.

    In this she could see for the first time that the “scruff” was actually a train of pulses spaced by one-and-a-third seconds. Bell and Hewish had discovered pulsars.

    But this wasn’t immediately obvious to them. Following Bell’s observation they worked for two months to eliminate mundane explanations for the signals.

    Bell also found another three sources of pulses, which helped to scotch some rather more exotic explanations, such as the idea that the signals came from “little green men” in extraterrestrial civilisations. The discovery paper appeared in Nature on February 24, 1968.

    Later, Bell missed out when Hewish and his colleague Sir Martin Ryle were awarded the 1974 Nobel Prize in Physics.[More discrimination.]

    A pulsar on ‘the pineapple’

    CSIRO’s Parkes radio telescope in Australia made its first observation of a pulsar in 1968, later made famous by appearing (along with the Parkes telescope) on the first Australian $50 note.

    Fifty years later, Parkes has found more than half of the known pulsars. The University of Sydney’s Molonglo Telescope also played a central role, and they both remain active in finding and timing pulsars today.

    U Sidney Molonglo Observatory Synthesis Telescope (MOST), Hoskinstown, Australia

    Internationally, one of the most exciting new instruments on the scene is China’s Five-hundred-metre Aperture Spherical Telescope, or FAST.

    FAST radio telescope, now operating, located in the Dawodang depression in Pingtang county Guizhou Province, South China

    FAST has recently found several new pulsars, confirmed by the Parkes telescope and a team of CSIRO astronomers working with their Chinese colleagues.

    Why look for pulsars?

    We want to understand what pulsars are, how they work, and how they fit into the general population of stars. The extreme cases of pulsars – those that are super fast, super slow, or extremely massive – help to limit the possible models for how pulsars work, telling us more about the structure of matter at ultra-high densities. To find these extreme cases, we need to find lots of pulsars.

    Pulsars often orbit companion stars in binary systems, and the nature of these companions helps us understand the formation history of the pulsars themselves. We’ve made good progress with the “what” and “how” of pulsars but there are still unanswered questions.

    As well as understanding pulsars themselves, we also use them as a clock. For example, pulsar timing is being pursued as a way to detect the background rumble of low-frequency gravitational waves throughout the universe.

    Pulsars have also been used to measure the structure of our Galaxy, by looking at the way their signals are altered as they travel through denser regions of material in space.

    Pulsars are also one of the finest tools we have for testing Einstein’s theory of general relativity.

    This theory has survived 100 years of the most sophisticated tests astronomers have been able throw at it. But it doesn’t play nicely with our other most successful theory of how the universe works, quantum mechanics, so it must have a tiny flaw somewhere. Pulsars help us to try and understand this problem.

    What keeps pulsar astronomers up at night (literally!) is the hope of finding a pulsar in orbit around a black hole. This is the most extreme system we can imagine for testing general relativity.

    Finally, pulsars have some more down-to-earth applications. We’re using them as a teaching tool in our PULSE@Parkes program, in which students control the Parkes telescope over the Internet and use it to observe pulsars. This program has reached over 1,700 students, in Australia, Japan, China, The Netherlands, United Kingdom and South Africa.Pulsars also offer promise as a navigation system for guiding craft travelling through deep space. In 2016 China launched a satellite, XPNAV-1, carrying a navigation system that uses periodic X-ray signals from certain pulsars.Pulsars have changed our our understanding of the universe, and their true importance is still unfolding

    So what can we expect these new radio projects to discover? We have no idea, but history tells us that they are almost certain to deliver some major surprises.

    Making these new discoveries may not be so simple. Gone are the days when astronomers could just notice something odd as they browse their tables and graphs.

    Nowadays, astronomers are more likely to be distilling their answers from carefully-posed queries to databases containing petabytes of data. Human brains are just not up to the job of making unexpected discoveries in these circumstances, and instead we will need to develop “learning machines” to help us discover the unexpected.

    With the right tools and careful insight, who knows what we might find.

    Travelling from Western Australia to Tasmania via the Great Australian Bight, the inaugural voyage in the program gave 20 postgraduate students two weeks of at-sea training on Board Australia’s advanced marine research vessel Investigator.

    CAPSTAN (Collaborative Australian Postgraduate Sea Training Alliance Network) is a national approach to developing the next generation of marine scientists and provides multidisciplinary at-sea training to meet the needs of industry and government.

    The program makes use of Investigator’s wide research capability to deliver training that ranges from seafloor coring and marine life surveys to sea survival skills and ship navigation using charts.

    Students even receive training in the traditional maritime skill of knot tying from the ship crew!

    The diverse training on offer was matched by the range of students and trainers on board the ship for the first CAPSTAN voyage.

    Twelve Australian universities were represented, along with staff from the Marine National Facility, reflecting the highly collaborative nature of the CAPSTAN program.

    CAPSTAN Director, Dr April Abbott from Macquarie University, said the first voyage had exceeded all expectations and provided more than a few memorable experiences.

    “The voyage has been amazing, and both students and trainers have described it as a once in a lifetime experience,” Dr Abbott said.

    “Students received training in sampling seafloor geology and sediments, studied the chemistry of the ocean and got up close to marine life, including some large pods of whales – and that was just the first couple of days.

    “So much has been learned about doing research at sea, and I’m sure everyone now has a greater appreciation of the impact that sea sickness can have on a research program.”

    Chief Scientist on the CAPSTAN voyage, Associate Professor Jochen Kaempf from Flinders University, echoed the many benefits that the CAPSTAN voyage had delivered.

    “CAPSTAN offers research-based training for students and this voyage has resulted in the collection of new scientific data that will help underpin our understanding of the marine environment,” Professor Kaempf said.

    “Students have assisted in 3D mapping previously unmapped regions of seafloor, revealing features that may play a vital role in coastal nutrient cycling in the Great Australian Bight region. CAPSTAN training involves the collection of real data and students are contributing to real world research.

    “For me, one of the highlights of the voyage was seeing a future generation of marine scientists plan and conduct a scientific program for a full day of the voyage. They all did an outstanding job.”

    Postgraduate student, Helen Hayes from University of Technology Sydney, said the voyage would be important for many students in helping shape future careers.

    “To have had the opportunity to train on board this impressive research ship with all the amazing people that make the science happen has been a highlight of my career. You learn so many things that you can’t find in books or in the classroom,” Ms Hayes said.

    “CAPSTAN provides at-sea training that is not available anywhere else in Australia and Ms Hayes said that the voyage had inspired many fellow students to continue following a career in the marine sciences.

    “There are so many opportunities that this training opens up. I hope to be back as a scientist on future voyages to help contribute to developing greater understanding about the marine environment, and how we manage it from impacts such as climate change.

    “It’s also really great to see such a strong representation of women in the program, both as trainers and students. The marine sciences are a great career path for women.”

    CAPSTAN will continue on board Investigator in coming years with a further two training voyages scheduled in the initial three-year pilot program.

    CAPSTAN is led by Macquarie University, supported by the Marine National Facility and governed by a network of leading industry and university partners. The program aims to provide a platform for institutional, industrial and generational knowledge transfer and collaboration to help support Australia’s growing blue economy, which is expected to contribute over $100billion a year to the Australian economy by 2025.

    From U Sidney: “Gravitational waves world-first discovery Down Under” 

    U Sidney bloc

    University of Sidney

    17 October 2017

    Sydney confirms radio emission from gravitational wave event.

    A Sydney team was the first in the world to confirm radio waves from the latest gravitational waves event, resulting from a spectacular neutron star merger that has produced light and radio waves as well as gravitational waves.

    How the discovery unfolded in Sydney.

    An Australian group was the first in the world to confirm the radio emission from a gravitational wave event, discovered by collaborators in the United States being announced today.

    The discovery of gravitational waves in 2015 was awarded the Nobel Prize for physics this year. The discovery of these ripples in space-time, produced by massive, accelerating bodies, like orbiting black holes (which cannot be seen directly) or neutron stars, confirms a prediction made by Albert Einstein in 1916.

    Now, a group led by Associate Professor Tara Murphy, from the University of Sydney and the Centre of Excellence for All-Sky Astrophysics (CAASTRO), has confirmed radio-wave emission from a gravitational wave event discovered on 17 August this year.

    The results are included in a Science paper published today with co-author institutions including the California Institute of Technology (Caltech) and Oxford University; simultaneously teams from the international science community are publishing related research in other leading journals, demonstrating the second epoch in gravitational waves discovery.

    Scientists representing LIGO-Virgo, and some 70 observatories today reveal the gravitational waves discovery – the first to produce light and radio waves, not just gravitational waves.

    The explosion, produced by a pair of neutron stars merging, took place in galaxy NGC 4993, about 130 million light-years away. The first follow-up detection was optical, about 11 hours after the event, and was detected by a number of groups worldwide. X-ray emissions were detected nine days later and radiowaves after 15 days.

    University of Sydney Associate Professor Tara Murphy, who leads the radio astronomy follow-up in Australia, said she was in the United States with colleague David Kaplan when they saw the gravitational wave announcement come through on the private email list of the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO).

    “We immediately rang our team in Australia and told them to get onto the CSIRO telescope as soon as possible, then started planning our observations,” she said.

    “We were lucky in a sense in that it was perfect timing but you have to be at the top of your game to play in this space. It is intense, time-critical science.”

    PhD candidate Dougal Dobie spent hours observing on the telescope. More details in today’s piece by Associate Professor Murphy in The Conversation.

    The team used the CSIRO’s Australia Telescope Compact Array to monitor the gravitational wave event for more than 40 hours over several weeks. Dr Douglas Bock, Director of CSIRO’s Astronomy & Space Science team, said this extraordinary detection by an Australian team, using Australian facilities, made a significant contribution to the global discovery.

    “Running a national facility involves providing researchers with access – fast – so they can monitor unexpected astronomical events of extraordinary scientific interest,” Dr Bock said.

    The ARC Centre of Excellence for Gravitational Waves (OzGrav) director Professor Matthew Bailes said: “Never before have we seen where in the Universe gravitational waves came from; the subsequent avalanche of science was virtually unparalleled in modern astrophysics.”

    University of Sydney Vice-Chancellor and Principal Dr Michael Spence said: “This international discovery, with Sydney playing an integral role, demonstrates that the best science and modern innovation is intrinsically a collaborative effort.

    “What better a way to confirm that Einstein’s theory of relativity was correct, gain insights into massive bodies like black holes and, with this knowledge, start to re-think our understanding of the Universe,” Dr Spence concluded.

    Our founding principle as Australia’s first university was that we would be a modern and progressive institution. It’s an ideal we still hold dear today.

    When Charles William Wentworth proposed the idea of Australia’s first university in 1850, he imagined “the opportunity for the child of every class to become great and useful in the destinies of this country”.

    We’ve stayed true to that original value and purpose by promoting inclusion and diversity for the past 160 years.

    It’s the reason that, as early as 1881, we admitted women on an equal footing to male students. Oxford University didn’t follow suit until 30 years later, and Jesus College at Cambridge University did not begin admitting female students until 1974.

    It’s also why, from the very start, talented students of all backgrounds were given the chance to access further education through bursaries and scholarships.

    Today we offer hundreds of scholarships to support and encourage talented students, and a range of grants and bursaries to those who need a financial helping hand.

    Minister for Education and Training, Senator the Hon Simon Birmingham working with East Adelaide Primary School students as part of STEM in Schools.

    The STEM in Schools event, run by CSIRO, Australia’s national science agency, forms part of National Science Week and will see classrooms across the country come alive with science as students participate in a virtual classroom discussion with STEM professionals working in the international space industry.

    Many also have the opportunity to take part in hands-on science activities with CSIRO scientists.

    More than 30 Federal MPs will also head back to school for the day and join students in the activities, underlining the national importance of STEM for Australia’s future.

    With research indicating that 75 per cent of the fastest growing occupations now require STEM skills and knowledge, it is now more important than ever to engage students in science, technology, engineering and maths.

    CSIRO Chief Executive Dr Larry Marshall said the event was about inspiring a curiosity and passion in science that will encourage more students to pursue STEM as a foundation of their future.

    “For Australia to prosper, we need to empower our students to calmly and confidently stare into the face of Australia’s challenges, knowing that science has the power to solve the impossible and turn challenge into opportunity,” Dr Marshall said.

    “STEM in Schools teaches our children how they can reshape the future, inspiring them with the possibilities of science. These students will go on to become our scientists, engineers, business leaders and entrepreneurs of tomorrow.”

    STEM in Schools events are taking place in over 350 schools around Australia, with over 70 CSIRO staff and 30 members of parliament visiting schools across the country to conduct activities and share their passion for STEM.

    Follow the conversation and see all the action from the events across the country with #STEMinSchools on Twitter, Facebook and Instagram.

    Astronomers working with our Compact Array telescope are beginning to suspect more and more stars of hiding a secret.

    We hadn’t noticed until now, but these stars may be ‘hairy’ – surrounded by a ‘mane’ of gas tendrils.

    Astro-sleuth Mark Walker (Manly Astrophysics) and his team came to the some-stars-are-hairy idea after using the Compact Array to study radio waves from distant, powerful galactic bodies called quasars.

    Quasars emit radio waves, but by the time they reach us on Earth, they have different properties — dimming and brightening rapidly. It seems something in space is making quasars twinkle. Quasar twinkling was first seen 30 years ago but until now its cause was a mystery.

    Mark and the team were observing a quasar near a bright, hot star called Spica, which lies in the constellation Virgo, and saw that it, too twinkled.

    Looking back at two other cases of quasar twinkling, observed with the Compact Array and other telescopes, the team found that they too occurred near hot stars: Vega (in the constellation Lyra) and Alhakim (in the constellation Centaurus).

    The chance of this happening at random is just one in ten million, the researchers say.

    So how are these hot stars linked to the quasars’ twinkling?

    By looking at the twinkling pattern, the astronomers were able to work out that the twinkling is caused by long, thin streams of gas radiating outward from the star.

    We already know one star that looks like this! It’s in the Helix Nebula, in the constellation Aquarius (as in the feature image).

    Here, a star is surrounded by globules of hydrogen gas, each about as big as our solar system. The ‘hair’ is created when UV radiation from the star blasts gas off the globules, creating long, thin streams.

    While the star in the Helix is old, younger stars might have these streams too, the researchers say.

    Their findings have been published in The Astrophysical Journal.

    From CSIRO: “Extreme El Niño events to stay despite stabilisation”

    The frequency of extreme El Niño events is projected to increase for a further century after global mean temperature is stabilised at 1.5°C above pre-industrial levels.

    Research published today in Nature Climate Change by an international team shows that if warming was halted to the aspirational 1.5°C target from the Paris Agreement, the frequency of extreme El Niño events could continue to increase, due to a continuation of faster warming in the eastern equatorial Pacific.

    CSIRO researcher and lead author Dr Guojian Wang said the growing risk of extreme El Niño events did not stabilise in a stabilised climate.

    “Currently the risk of extreme El Niño events is around five events per 100 years,” Dr Wang said.

    “This doubles to approximately 10 events per 100 years by 2050, when our modelled emissions scenario (RCP 2.6) reaches a peak of 1.5°C warming.

    “After this, as faster warming in the eastern equatorial Pacific persists, the risk of extreme El Niño continues upwards to about 14 events per 100 years by 2150.

    “This result is unexpected and shows that future generations will experience greater climate risks associated with extreme El Niño events than seen at 1.5°C warming.”

    The research was based on five climate models that provided future scenarios past the year 2100.

    The models were run using the Intergovernmental Panel on Climate Change’s lowest emissions scenario (RCP2.6), which requires negative emissions late in the century.

    Director of the Centre for Southern Hemisphere Oceans Research and report co-author, Dr Wenju Cai, said that this research continues important work on the impacts of climate change on the El Niño-Southern Oscillation which is a significant driver of global climate.

    “The most severe previous extreme El Niño events occurred in 1982/83, 1997/98 and 2015/16, years associated with worldwide climate extremes,” Dr Cai said.

    “Extreme El Niño events occur when the usual El Niño Pacific rainfall centre is pushed eastward toward South America, sometimes up to 16,000 kilometres, causing massive changes in the climate. The further east the centre moves, the more extreme the El Niño.

    “This pulls rainfall away from Australia bringing conditions that have commonly resulted in intense droughts across the nation. During such events, other countries like India, Ecuador, and China have experienced extreme events with serious socio-economic consequences.”

    Dr Cai added that while previous research suggested that extreme La Niña events would double under a 4.5°C warming scenario, results here indicated that under a scenario of climate stabilisation (i.e. 1.5°C warming) there was little or no change to these La Niña events.

    The research was conducted by researchers at the Hobart based Centre for Southern Hemisphere Oceans Research, an international collaboration between CSIRO, Qingdao National Laboratory for Marine Science and Technology, the University of New South Wales, and the University of Tasmania.

    The National Environmental Science Programme’s Earth System and Climate Change Hub co-funded this research.
