25.01.2022 Neutron star collisions do not create the quantity of chemical elements previously assumed, a new analysis of galaxy evolution finds. The research also reveals ...that current models can’t explain the amount of gold in the cosmos creating an astronomical mystery. ASTRO 3D astronomers researchers Chiaki Kobayashi at University of Hertfordshire and Amanda Karakas at Monash University, together with Maria Lugaro from Hungary's Konkoly Observatory, used computer modelling to develop a new-look Periodic Table, showing the stellar origins of naturally occurring elements from carbon to uranium.

25.01.2022 Does cutting your contribution to climate change also improve your mental health? Researchers want to know how you’re dealing with eco-anxiety. The public healt...h scientists from Melbourne’s Deakin University University and Monash University are exploring how bad news about the environment brings us down and whether taking even small actions on climate change boosts our mental health. To find out, they are asking people to take a survey which aims to understand the mental health impacts of climate change. Read the full story: https://www.scienceinpublic.com.au/abc/tempcheck

24.01.2022 How do stars destroy lithium? Was a drastic change in the shape of the Milky Way caused by the sudden arrival of millions of stellar stowaways? These are just a... couple of the astronomical questions likely to be answered following the release today of ‘GALAH DR3’, the largest set of stellar chemical data ever compiled. The data, comprising more than 500 GB of information gleaned from more than 30 million individual measurements, was gathered by astronomers including Sven Buder, Sarah Martell and Sanjib Sharma from Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) using the Anglo Australian Telescope (AAT) at the Australian Astronomical Observatory at Siding Spring in rural New South Wales.

24.01.2022 , Global Change Biology . Previously, current ...models underestimated the impact of hurricanes and typhoons on coral reef communities assuming wave damage occurred primarily within 100 kilometres of its track. To test the consequences of using the standard distance-based model, Dr Marji Puotinen and colleagues collected existing information on cyclone size and frequency, crunching data gathered between 1985 and 2015 for 150 coral reef ecoregions around the world. The team includes researchers from Australian Institute of Marine Science, the The University of Western Australia and the Indian Ocean Marine Research Centre (UWA).

23.01.2022 Vaccines alone won’t keep Australia COVID-safe, review finds. High levels of testing, efficient vaccine distribution and addressing pandemic mental health impac...ts are critical if Australia is to maintain control over COVID-19 in 2021, the country’s learned body for health and medical sciences has concluded. The Australian Academy of Health and Medical Sciences (AAHMS), an independent body comprising more than 400 senior researchers, has released a report spelling out the necessary next steps for pandemic response in the new year.

20.01.2022 Bend it like Einstein: Astronomers turn galaxies into magnifiers. Astronomers have turned a cluster of galaxies into a gargantuan magnifying lens, using it to study another galaxy, 10.7 billion light years away, in unprecedented detail. Taking advantage of a phenomenon known as gravitational lensing, the team of scientists, led by NASA Goddard Space Flight Centre scientist Dr Soniya Sharma, identified star forming regions in the distant and ancient galaxy....

19.01.2022 Children in remote and regional schools will soon be visited by astronomers bearing gifts in a quest to kindle interest in the cosmos. The scientists drawn fr...om the ranks of the ARC Centre of Excellence for All Sky Astrophysics in 3D (ASTRO 3D) and The Australian National University will donate a powerful telescope and high-tech accessories to each school so classes can continue to explore the Universe long after the astronomers have left.

18.01.2022 At cosmic noon, puffy galaxies make stars for longer. Massive galaxies with extra-large extended puffy disks produced stars for longer than their more compact... cousins, new modelling reveals. In a paper published in the Astrophysical Journal, researchers led by Dr Anshu Gupta and Associate Professor Kim-Vy Tran from Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D), show that the sheer size of a galaxy influences when it stops making new stars.

The guidelines are the result of four years of extensive review of the evidence on the harms and benefits of drinking alcohol. They replace the previous version, published in 2009. They will underpin policy decisions and public health messaging for many years to come. Read more: https://bit.ly/345cKxh

11.01.2022 Milky Way ancient star orbits are more diverse than thought, prompting a rethink on galaxy evolution, astronomers led by the University of Padova’s Giacomo Cord...oni and Gary Da Costa from The Australian National University and ASTRO 3D reveal in a new paper in the Monthly Notices of the Royal Astronomical Society (MNRAS). The research involved a team from ANU, University of Padova, Monash University, Massachusetts Institute of Technology (MIT), Uppsala University, the Max Planck Institute for Astronomy in Germany and Stockholm University.

10.01.2022 Designer crops, animals, babies? Genome editing is too important to be left to the experts, say University of Canberra’s John Dryzek et al today in Science. Th...e practice of genome editing which alters an organism’s DNA in ways that could be inherited by subsequent generations is both more complex and less dramatic than the popular tropes suggest. However, its implications are so profound that a growing group of experts believe it is too important a matter to be left only to scientists, doctors and politicians. 25 leading researchers from across the globe call for the creation of national and global citizens’ assemblies, made up of lay-people, tasked with considering the ethical and social impacts of this emerging science.

08.01.2022 Milky Way not unusual, astronomers find. Detailed cross-section of another galaxy reveals surprising similarities to our home. The first detailed cross-section ...of a galaxy broadly similar to the Milky Way, published today, reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt. The galaxy, dubbed UGC 10738, turns out to have distinct ‘thick’ and ‘thin’ discs similar to those of the Milky Way. This suggests, contrary to previous theories, that such structures are not the result of a rare long-ago collision with a smaller galaxy. They appear to be the product of more peaceful change. And that is a game-changer. It means that our spiral galaxy home isn’t the product of a freak accident. Instead, it is typical.

03.01.2022 More than 60 years to achieve gender equity? It will take until at least 2080 before women make up just one-third of Australia’s professional astronomers, an an...alysis published today in the journal Nature Astronomy reveals. Astronomers have been leaders in gender equity initiatives, but our programs are not working fast enough, says Professor Lisa Kewley, director of the ARC Centre of Excellence for All-Sky Astrophysics in 3 Dimensions (ASTRO 3D).

03.01.2022 The secrets of 3000 galaxies laid bare. The complex mechanics determining how galaxies spin, grow, cluster and die have been revealed following the release of a...ll the data gathered during a massive seven-year Australian-led astronomy research project. The scientists observed 13 galaxies at a time, building to a total of 3068, using a custom-built instrument called the Sydney-AAO Multi-Object Integral-Field Spectrograph (SAMI), connected to the 4-metre Anglo-Australian Telescope (AAT) at Siding Spring Observatory in New South Wales. The telescope is operated by the Australian National University. Read more: http://bit.ly/36B5dHN Image credit: Scott Croom/University of Sydney
