Australian-led GALAH project releases chemical information for 600,000 stars.
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.
Australian researchers find ways to overcome the blinding glare of quasars
NASA’s James Webb Space Telescope will uncover galaxies never before seen by humanity, Australian-led research reveals.
The telescope, due to launch in late 2021, is the largest, most powerful and complex space telescope ever built.
Two new studies led by Madeline Marshall from Australia’s University of Melbourne and the ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) find that the Webb will be able to reveal galaxies currently masked by powerful lights called quasars.
Ethical and social implications of powerful DNA-altering technology are too important to be left to scientists and politicians, researchers find.
Designer babies, mutant mozzies and frankenfoods: these are the images that often spring to mind when people think of genome editing.
The practice – 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.
Writing in the journalScience, 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.
Research conducted by former Fresh Science participant Dale Robinson has been covered in the 2020-2021 edition of Defence Science and Technology’s Outlook magazine.
Dr Robinson is a biomedical engineer at the University of Melbourne.
Minimising severe injury from blast events on military vehicles
Blast events inflicted on military vehicles are a consistent threat in contemporary conflicts. Developing equipment that better protects soldiers from this threat has become the focus of significant military research. It is critical to understand how severe injuries are inflicted and how forces from blast events are transmitted to the human body in order to strengthen blast protection for soldiers.
Research finds current models underestimate the impact of hurricanes and typhoons on coral reef communities
Big and strong cyclones can harm coral reefs as far as 1000 kilometres away from their paths, new research shows.
A study led by Dr Marji Puotinen from the Australian Institute of Marine Science (AIMS) sounds a warning about the way strong cyclone winds build extreme seas that affect coral reefs in Australia and around the world.
Conventional modelling used to predict how a cyclone, hurricane or typhoon might impact corals assumes that wave damage occurs primarily within 100 kilometres of its track.
Unusual galaxy set to prompt rethink on how structures in the Universe form
Astronomers have captured an image of a super-rare type of galaxy – described as a “cosmic ring of fire” – as it existed 11 billion years ago.
The galaxy, which has roughly the mass of the Milky Way, is circular with a hole in the middle, rather like a titanic doughnut. Its discovery, announced in the journalNature Astronomy, is set to shake up theories about the earliest formation of galactic structures and how they evolve.
Research finds rehab-only treatment yields better long-term results
Knee reconstructions may lead to more problems later in life than non-surgical rehabilitation, researchers have found.
A team led by Dr Adam Culvenor from La Trobe University looked at health outcomes for athletes with damaged anterior cruciate ligaments (ACL) – a devastating injury, particularly common among footballers.
Australian scientists flag dramatic improvement to next-gen perovskite R&D
Tests on new designs for next-gen solar cells can now be done in hours instead of days thanks to a new system built by scientists at Australia’s Monash University, incorporating 3D-printed key components.
The machine can analyse 16 sample perovskite-based solar cells simultaneously, in parallel, dramatically speeding up the process.
The invention means that the performance and commercial potential of new compounds can be very rapidly evaluated, significantly speeding up the development process.
