World’s oldest gem leading us to hidden treasures

Zircon, the oldest mineral on the planet, is helping geologists understand how Earth started out and how it continues to evolve. By better understanding the Earth’s structure, mining companies have been able to find new mineral deposits.

“Most of the mineral deposits that are exposed on the surface of the planet have already been found and mined, but we need to find the ones that are still hidden,” Dr Elena Belousova says.

She and her colleagues at the ARC Centre of Excellence for Core to Crust Fluid Systems have developed TerraneChron®, a tool that looks at zircons found in geological samples, such as rocks or sand in river beds, to find out when they crystallised.

Cool Kids goes bush – helping rural children with anxiety

Just under half the children in Australia with a mental health issue aren’t receiving the appropriate treatment, and one third of their parents say the main impediment is a lack of access to treatment options.

“We’ve got all these great programs that we know work, but kids in rural Australia have just not been getting access to them,” says Dr Lauren McLellan, a clinical psychologist and Research Fellow at the Centre for Emotional Health.

Genetics guiding anxiety treatment

For years we’ve been identifying genetic markers linked to mental disorders. Now it appears those same markers could also tell us who will best-respond to treatment.

A study of over 1,500 children, as part of the international Genes for Treatment collaboration, found those with a specific genetic marker were more responsive to psychological therapy than those without.

Building an emotionally healthy community

A unique national centre is working to build an emotionally healthy community through science and practice.

From four-year-olds with anxiety, to 90-years-olds with depression, the Centre for Emotional Health at Macquarie University takes a ‘lifespan approach’ to mental health.

They’ve spent the past 20 years studying, developing, testing and rolling out mental health programs – which are now available in eight languages and 15 countries including Denmark, the UK and Norway.

Predicting change, brains, trains and mental health

State Awards

“Trait-based ecology” enables Macquarie University’s Mark Westoby to explain patterns of species occurrence and abundance and to understand the impacts of climate change and changing patterns of land use. He received the $55,000 NSW Scientist of the Year.

Nanocapsules for drugs delivery: Frank Caruso is making miniature capsules that could better deliver drugs for cancer, AIDS and cardiovascular diseases. He won one of the 2014 Victoria Prizes for Science & Innovation worth $50,000.

Micro muscles bend to the task

A breakthrough in the electroactive polymers used to make electrically controlled micro “artificial muscles” could be important for future drug delivery in the body, as well as a having a host of other applications.

The new research, conducted at the Australian National Fabrication Facility’s (ANFF) materials node at the University of Wollongong (UOW) in NSW has produced materials which, unlike earlier versions, do not need to be immersed in an electrolyte solution. They are self-sufficient and can even work in air. Continue reading Micro muscles bend to the task

When the present upgrade is complete, the Sydney University Stellar Interferometer (SUSI) will be able to resolve objects the size of a beach ball on the Moon, says Mike Ireland of Macquarie University in Sydney. This large interferometer will be used to determine the dimensions—size, weight and velocity—of pulsating stars, hot stars, and massive stars. SUSI will also be involved in the search for binary stars and their planetary companions. Continue reading Seeing a beach ball on the moon
