Statisticians have revealed the surprising source of dust that plagues townships beside a Hunter Valley rail line delivering coal to Newcastle’s busy port.
Airborne dust increases as trains pass. But it wasn’t clear exactly how—for example, whether the dust was escaping uncovered coal wagons or coming from the diesel engines pulling the wagons. The answer was surprising.
Mathematicians from the ARC Centre of Excellence for Mathematical and Statistical Frontiers correlated air-pollution data against information on passing trains and weather conditions.
The design of a 3D silicon chip architecture clears another hurdle in the international race to build quantum computers.
Researchers at the University of Melbourne and the University of New South Wales (UNSW) have designed a chip based on single atom quantum bits, creating a blueprint for building a large-scale silicon quantum computer.
It’s very hard to set up a jet engine in a wind tunnel and get accurate measurements inside it while it’s rotating 7,000 times a minute.
So while other members of the University of Melbourne’s mechanical engineering department use wind tunnels to measure turbulence on the surface of airplanes, Professor Richard Sandberg has developed a computer program to make the same measurements inside an engine.
His work also applies to the turbines used to generate power from gas, wind and wave.
Pairing psychology with cancer treatment has a profound impact on the wellbeing of patients, Associate Professor Maria Kangas and her team at the Centre for Emotional Health have found.
In a recent clinical trial, head and neck cancer patients were offered weekly cognitive behavioural therapy (CBT) sessions concurrent to their radiation therapy appointments.
After just seven sessions, patients reported a significant decline in cancer-related anxiety and/or depression. And after a year, 67 per cent were no longer experiencing any anxiety or depression and were doing better than the control group who had received regular counselling, but not CBT.
A new printing technology can now simultaneously print living stem cells and the environment they need to survive and become the right cell type. The first application is a cartilage repair kit.
“Our current 3D printers can integrate living and non-living materials in specific arrangements at a range of scales, from micrometres to millimetres,” says Professor Gordon Wallace, Director of the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong.
“And we’re developing new approaches that will enable 3D printing of nano-dimensional features.”
Seagrass meadows provide food and habitat for everything from dugongs and birds to fish and tiny crabs.
Globally we’re losing over 100 sq. km per year due to dredging, coastal developments and runoff. That’s bad news for the animals they support, and bad news for us too, as seagrass supports healthy coastal fisheries as well as acting as a carbon store.
To see how seagrass can be given a fighting chance, Dr Paul Wu at the ARC Centre of Excellence for Mathematical and Statistical Frontiers and collaborators have put an extended modelling technique to new use, predicting seagrass health and suggests how some modified human activities could reduce the damage.
A stable and compact nuclear waste technology is moving from research level to industrial-scale at the Australian Nuclear Science and Technology Organisation (ANSTO).
The planned full-scale nuclear waste treatment plant incorporates ANSTO’s Synroc innovation that locks away radioactive waste products by mimicking natural geology.
“A key part of the Synroc process is Hot Isostatic Pressing, which applies heat and pressure to minimise the disposal volume and transform liquid radioactive waste into a chemically durable material suitable for long term storage,” says Gerry Triani, Technical Director at ANSTO Synroc.
