Solving the problem of how to store energy is essential for a future run on renewables.
That’s why promising materials for hydrogen fuel cells and high capacity, long-lived batteries are being explored at the atomic level by the Australian Synchrotron.

Australian Synchrotron scientist Dr Qinfen Gu is investigating a new class of hydrogen storage materials being developed by scientists at the University of Wollongong and their international collaborators.Qinfen is using the powerful X-rays of the synchrotron to observe and analyse the structure of these materials.

Our blood has a built-in system for breaking up heart attack-inducing clots—and we’re a step closer to drugs that could switch that system on at will.

Australian researchers have won the decades-long race to define the structure of plasminogen—a protein whose active form quickly dissolves blood clots.
The current crop of clot-busting drugs have many side effects, including bleeding and thinning of the blood, so harnessing the body’s own mechanism for clearing clots could offer a better way. Continue reading Clues to switching off your blood clots→
Many plastics and polymers—including paints, glues and lubricants—will be transformed in the coming years by the work of Australian chemists, Professors David Solomon and Ezio Rizzardo.

Their work is integral to more than 500 patents and their techniques are used in the labs and factories of DuPont, L’Oréal, IBM, 3M, Dulux and more than 60 other companies.
Eventually, the pair’s chemical theories and processes will influence hundreds of products.
Unhealthy cells are less “squishy” than their healthy counterparts. That difference is used by a small device developed by engineers at Monash University to test living blood cells for diseases, such as malaria and diabetes. The device can then sort the cells for future culturing and experimentation without harming them.

The patented “lab-on-a-chip” and accompanying control system has attracted considerable interest from pharmaceutical companies, according to co-inventor Dr Greg Sheard of the Department of Mechanical and Aerospace Engineering. Continue reading Health check for live cells→
A new brain implant could deliver anti-epilepsy drugs straight to where they’re needed and, in future, on demand. This will be particularly helpful for the 30 per cent of epilepsy patients who suffer severe side-effects, such as nausea, rashes, weight change and dizziness, from their medication, leaving them unable to be treated.

The implant is a biodegradable polymer that ARC Centre of Excellence for Electromaterials Science associate Bionics program leader A/Prof Simon Moulton compares to the types of polymers used in dissolvable stitches. Continue reading On-demand epilepsy drug→
CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) telescope is already booked out for much of its first five years of data gathering, even before it formally begins early operations in 2013.

More than 400 astronomers from over a dozen nations have already signed up to look for pulsars, measure cosmic magnetic fields, and study millions of galaxies.
ASKAP was built at the specifically radio-quiet Murchison Radio-astronomy Observatory (MRO) in Western Australia as a technology demonstrator for the $2 billion Square Kilometre Array radio telescope. Continue reading Wide open skies for Australian astronomy→
An Australian physicist is unravelling the mystery of how the hot, brilliant stars we see today emerged from our Universe’s “dark age”.

Theoretical physicist Prof Stuart Wyithe is one of the world’s leading thinkers on the Universe as it was 13 billion years ago, when there were no stars or galaxies, just cold gas.
In the next few years astronomers will learn much more as powerful new telescopes come online.
The Earth is losing species and ecosystems fast, but figuring out the best response is not easy when information, time and money are scarce.

Dr Eve McDonald-Madden is using maths to help governments and others make tough decisions on how best to use limited resources to preserve ecosystems under threat.
The young Australian scientist helps to save species, not by going out into the field, but by analysing the data other people have collected on endangered species. Continue reading The mathematics of conservation→
A new fibre optic medical tool is revolutionising our understanding of serious but socially embarrassing digestive illnesses, such as constipation, diarrhoea and irritable bowel syndrome. Thanks to this device, medical scientists can see for the first time the coordinated, fine and complex muscular activity of the human digestive system in action.

CSIRO optical physicist Dr John Arkwright, together with Dr Philip Dinning, of Flinders University, collected a 2011 Eureka Prize for their creation of the fibre optic catheter, which gleans information about digestive function by measuring pressure.

Neutrons and native frogs are an unlikely but dynamic duo in the battle against antibiotic-resistant bacteria, commonly known as superbugs, recent research has shown.

The skin secretions of the Australian green-eyed and growling grass frogs contain peptides (small proteins) that help frogs fight infection. Researchers hope these peptides will offer a new line of defence against a range of human bacterial pathogens, including methicillin-resistant Staphylococcus aureus (MRSA).
