Australian-led astronomers find the most iron-poor star in the Galaxy, hinting at the nature of the first stars in the Universe.
A newly discovered ancient star containing a record-low amount of iron carries evidence of a class of even older stars, long hypothesised but assumed to have vanished.
In a paper published in the journal Monthly Notices of
the Royal Astronomical Society: Letters, researchers led by Dr Thomas
Nordlander of the ARC Centre of Excellence for All Sky Astrophysics in 3
Dimensions (ASTRO 3D) confirm the existence of an ultra-metal-poor red
giant star, located in the halo of the Milky Way, on the other side of the
Galaxy about 35,000 light-years from Earth.
Discovering our changing planet: a perfect France–Australia partnership
Professor Kurt Lambeck is one of Australia’s most eminent scientists—a geophysicist who revealed how the Earth changes shape and how these changes are tied to sea levels, the movement of continents, and the orbits of satellites. Vital to his career have been French collaborations that now span almost half a century.
The brainpower of 18 institutions and more than $30 million are expanding the net to detect gravitational waves—disturbances in the fabric of spacetime—and cement Australia’s role in the emerging field.
Dating of ancient human teeth discovered in a Sumatran cave site suggests modern humans were in Southeast Asia 20,000 years earlier than previously thought.
The international research, led by Dr Kira Westaway from Macquarie University and published in Nature, has pushed back the timing of when humans first left Africa, their arrival in Southeast Asia, and the first time they lived in rainforests.
Your smartphone’s Wi-Fi connections are fast and reliable thanks to the work of Australian astronomers in the 1990s.
Today, your phone is also being protected from cyberattacks by Australian software that works within the kernel of the phone’s operating system to protect it from hacking and software faults. The kernel is the most fundamental part of an operating system. It acts between the hardware and the applications.
Now Australian researchers are working to secure America’s growing fleets of autonomous machines, with ‘microkernel’ software known as seL4.
The new software is built on the work of researchers at the University of New South Wales and National ICT Australia (now CSIRO’s Data61 Group).
The work of Indonesian and Australian scientists is resulting in re evaluation of Jakarta’s seismic risk by Indonesian Government agencies.
The team is scanning the Earth from thousands of kilometres in the air, right down to chemical traces found in rocks, as they hunt out telltale signs of future earthquakes and the damage they might do. They’ve highlighted a major new seismic threat for East Java as well as the tsunami threat to Bali, Lombok, Nusa Tenggara, and other coasts along the Flores Sea; and have identified active faults in the Nusa Tenggara region of Eastern Indonesia, measuring the rates of strain building up.
Indonesian and Australian scientists are part of a team searching for buried treasure: using the movement of tectonic plates to predict when and where giant deposits of gold and copper should form, while building an understanding of the conditions these deposits are created in.
The project, which was begun in 2013 and due for completion in 2016, is using Southeast Asia as a ‘natural laboratory’ to explore these natural processes and their products. Knowing when and how deposits formed can help us understand geological processes occurring today.
A team from Universitas Gadjah Mada (UGM) and the Australian National University (ANU) are planning to use thousands of sensors to monitor heat, noise, human activity and power usage in commercial buildings in Yogyakarta. This data will help them design a real-time monitoring system that saves energy and can be used in commercial buildings across Indonesia.
Energy demand in Indonesia has grown by 150 per cent over the last 30 years. Electricity supply is struggling to keep up—blackouts are common in hospitals, hotels, offices, shopping centres and university laboratories.
