The benefits of using medical-grade honey to treat and prevent infection in wounds has been confirmed by Sydney researchers.
Dr Nural Cokcetin tested more than 600 Australian honey samples and documented the antibacterial activity, which strongly corresponds to the levels of methylglyoxal (MGO), one of honey’s most active ingredients.
School-aged children are surrounded by messages about food and nutrition, from shop signs to brand advertising. Linguists from Indonesia and Australia have developed a new way of studying how this affects them, using smartphones and clever analysis.
In a project financed by The Australia-Indonesia Centre and led by Dr Sisilia Halimi of Universitas Indonesia and Professor Lesley Harbon of the University of Technology Sydney, researchers used their phones to take pictures of the ‘linguistic landscape’ around schools and their surrounds, in fact anywhere written text was evident.
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.
It’s not due to begin operating until 2013, but astronomers from around the world are already lining up to use CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP). In fact, the first five years of ASKAP’s operation are already booked out, with ten major international Survey Science projects looking for pulsars, measuring cosmic magnetic fields, studying millions of galaxies, and more.

Ken Freeman is hunting for fossils. But he’s not looking for old bones—he’s exploring the very origin and history of our Milky Way galaxy.
Conventional theory says that our galaxy grew big by engulfing smaller ones. If this is correct, stars from the original galaxies should be still identifiable within the main mass of stars via several tell-tale signs, from unusual velocities to spectral types. These stellar fossils would point to the galaxy’s birth and growth. Continue reading Galactic archaeology— digging into the Milky Way’s past→
Advanced telescopes need advanced astronomers to run them. Australia is matching the millions of dollars it is investing in new telescope technology with funds to help train the rising stars of Australian astronomy.
“We’ve had big investments in infrastructure, and now we need young scientists with the expertise to use them,” says Elaine Sadler, professor of Astrophysics at the University of Sydney and chair of the National Committee for Astronomy.
One new tranche of research funding for early career astronomers comes in the form of three-year Super Science Fellowships from the Commonwealth Government. In 2011, 14 young astronomers became Super Science Fellows, joining the 17 who started work in 2010. All up, astronomy will receive one-third of the Federal Government’s $27 million commitment to the Fellowships program. Continue reading Nurturing super astronomers at home→
Cracking the puzzle of unusual molecules in deep space that absorb some wavelengths of starlight is like unlocking the secrets of the Rosetta Stone, according to Rob Sharp of the Australian National University’s Research School of Astronomy and Astrophysics. “It’s the longest-standing problem in astronomical spectroscopy,” he says.
