China and Australia are the world’s two largest producers of gold. So, it’s fitting that a device combining Australian and Chinese research, and capabilities in high-tech manufacturing, is set to shake up the industry.
Ore processors need to know how much gold is in their raw material to get the most out of it. The current industry standard for testing ore is the fire assay, an elaborate and time-consuming process that requires temperatures over 1000 degrees and toxic chemicals such as lead. It also takes at least 8 hours to complete.

In a whisper-quiet area of the outback in Western Australia, 133,000 radio
telescope antennas are about to be built.
When complete, they’ll be able to pick up radio signals from
the time when the first stars in the universe formed.

Healthy soil for a healthy planet
To rein in global warming, scientists believe it will not be
enough to reduce our greenhouse gas emissions: we will also need to remove CO2
from the atmosphere.
Soils are an important reservoir for carbon, as they contain
nearly double that found in the atmosphere and vegetation combined.
Agricultural practices have degraded soil carbon stocks, so there is a large
potential for atmospheric carbon to be sequestered in soils.

Sonar and satellites reveal the fish and other creatures that live far below the surface.
The depths of the ocean still hold great mysteries. At depths between 200 and 1,000 metres live creatures that, taken altogether, weigh as much as 10 billion tonnes.
Rudy Kloser, an expert on echo sounding and deep-sea ecosystems at CSIRO in Hobart, says these creatures are vital but poorly understood. Continue reading Spying on the denizens of the Southern Ocean
Australian-made mirrors are helping the Mediterranean country of Cyprus move to renewable energy and secure its supply of drinking water.
Though Cyprus is blessed with plentiful sunshine, rainfall is low and the country depends on energy-intensive desalination plants for its drinking water. Continue reading Australian mirrors helping to power Cyprus
Changing lives together: from water to astronomy to cancer, this collection showcases outstanding collaborations between French and Australian researchers.
Scientific collaboration between Australia and France stretches back to the early days of European settlement, when La Pérouse built an observatory at Botany Bay in 1788.

A new kind of wheat high in resistant starch can improve intestinal health
Bowel cancer is the world’s third most common cancer. A diet that includes more resistant starch, a kind of fibre that feeds good bacteria in the large intestine, can make it less common. Resistant starch helps improve gut health and reduces the risk of conditions such as diabetes, obesity, heart disease and cancer.
Since 2006, CSIRO scientists have been working in a joint venture with French company Limagrain Céréales Ingrédients and the Grains Research and Development Corporation to develop wheat with more resistant starch. Continue reading Wheat that’s good for guts
Australia’s pioneering 3D metal printing technology is now at work in Toulouse, printing components for the French aerospace company, Safran Power Units.
3D printing has the potential to transform manufacturing, allowing rapid prototyping of components, and the creation of lighter and more efficient components that would be impossible to make using traditional casting technologies. But there are many challenges to overcome to ensure that the components meet the intense engineering and regulatory requirements of the aerospace industry. Continue reading Printing in metal
A perfect view of the Milky Way
On a series of calm, cool mornings in April 2017, 70 French scientists (from the French space science agency CNES, CNRS IRAP, and the Université Paul Sabatier de Toulouse) launched three enormous balloons into the sky above the heart of Australia.
CNES was using the Alice Springs Balloon Launching Centre (ASBLS) to send three precision scientific instruments up to altitudes of 30–40 kilometres to make observations that are impossible from the ground.
