The ‘coolest’ place for astronomy

High on the Antarctic Plateau, in one of the coldest places on Earth, a group of telescopes are peering through stellar dust clouds into the heart of our galaxy.

The cold helps counteract interference from the telescopes and surrounding equipment, which can hinder our ability to see relatively
‘cool’ objects in space, such as asteroids, young stars, and interstellar gas.

More wheat, less water

China and Australia can dramatically boost wheat yields and improve food security by unlocking the genetic potential within the hundreds of wheat varieties grown in the two countries. That’s the promise of the latest collaboration between wheat researchers in the two countries.

Chinese farmers have been growing wheat for at least 4,000 years. Crop yields per hectare are now nearly 10 times higher than in 1960 and China is now the largest wheat producer in the world. But wheat researchers say we can do more.

From sky to hospital

Working together to create advanced manufacturing industries

The maiden flight of the COMAC C919 airliner in May 2017 illustrated China’s ambition in advanced manufacturing.

Many of the airliner’s parts are made using 3D printing, and Australian engineers are working with their Chinese colleagues to develop the technology further.

A New Hope for Coral Reefs: Largest-Ever Study Unlocks Global Solution to Save Coral Communities

Scientists urge priority action on hundreds of surviving reefs.

The majority of 2500 reefs surveyed in a major international exercise retain the coral species that give them their distinctive structure.

More than 80 marine scientists, including several from Australia, contributed to the study, which is published in the journal, Nature Ecology and Evolution.

Searching for insight? Maybe get into nature

Early results from Australia-wide experiment suggest being outdoors can be a good way to trigger “aha” moments.

People are most likely to have a sudden bright idea when out in the bush – or lying in bed.

That’s one of the early observations arising from The Aha! Challenge, the month-long Australia-wide science experiment that kicked off during National Science Week and runs until the end of August.

The experiment, which revolves around a series of online brainteasers, aims to explore sudden bursts of clarity and insight, and their role in problem-solving. In effect, it’s a nationwide quest to find the things that make you go “aha!

And so far the results have been very revealing.

Using quantum dots and a smartphone to find killer bacteria

Australian scientists develop cheap and rapid way to identify antibiotic-resistant golden staph (MRSA).

A combination of off-the-shelf quantum dot nanotechnology and a smartphone camera soon could allow doctors to identify antibiotic-resistant bacteria in just 40 minutes, potentially saving patient lives.

Staphylococcus aureus (golden staph), is a common form of bacterium that causes serious and sometimes fatal conditions such as pneumonia and heart valve infections. Of particular concern is a strain that does not respond to methicillin, the antibiotic of first resort, and is known as methicillin-resistant S. aureus, or MRSA.

Recent reports estimate that 700 000 deaths globally could be attributed to antimicrobial resistance, such as methicillin-resistance. Rapid identification of MRSA is essential for effective treatment, but current methods make it a challenging process, even within well-equipped hospitals.

Gender bending: baby turtles influence their own sex

Chinese-Australian research finds climate change good news, and solves an evolutionary mystery

Baby turtles influence their gender by moving around inside their eggs, research has revealed.

The idea that an embryo reptile can act in a way that affects its chances of developing as male or female has long been thought impossible, but findings by scientists from China and Australia have now provided clear proof of the process.

The research, published in the journal Current Biology, solves a long-standing evolutionary mystery – and offers hope that at least some species thought especially vulnerable to effects of climate change will prove more robust than thought.

Anaemic star carries the mark of its ancient ancestor

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.

Aussie sharks still at risk from industrial fishing, despite protections

Macquarie University’s Professor Rob Harcourt urges Oceania-wide action to safeguard several species.

Sharks in Australian waters are well protected but are at risk as soon as they leave them, a new international study reveals.

The study compiled by 150 scientists around the world – including 26 with ties to Australia – has found that even in the most remote parts of the world’s oceans migratory sharks are in severe danger from commercial fishing fleets, new research reveals.

In a paper published in the journal Nature, more than 150 scientists, including Professor Rob Harcourt from the Department of Biological Sciences at Australia’s Macquarie University, report that the sharks – which include iconic species such as the shortfin mako (Isurus oxyrinchus)  and the great white (Carcharodon carcharias) – congregate in food-rich areas that are also prime hunting grounds for commercial longline fishing fleets.

Astronomer flies high to spy on star formation

Dr Stuart Ryder is venturing into the stratosphere on a NASA jet to study the birthplace of massive stars.

Macquarie University astronomer Dr Stuart Ryder is in New Zealand to hitch a ride on a NASA jet and take a closer look at how stars are born in one of the most active stellar nurseries ever seen.

“We’re looking at a molecular cloud called BYF73, which is collapsing in on itself at extremely high speeds and forming massive stars,” says Stuart, who is an Adjunct Fellow with the Department of Physics and Astronomy at Macquarie University.
