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.
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.
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→
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.
A Macquarie University start-up that created a new way to develop drugs faster and more cheaply than current methods, has won a CSIRO innovation award.
Currently it takes over a decade and $2 billion to develop a new drug. Of these, four out of five will never be launched.
If we want everyone in need to have access to affordable and effective medications, we must reduce the time and cost associated with drug development, argues Molecular Sciences’ Professor Peter Karuso.
