The devastating bushfires in Victoria, Australia on 7 February 2009 resulted in the loss of 173 lives and caused major property and asset damage. The fires are considered to be Australia’s worst peacetime disaster.

Research combats invasive ants on Indigenous lands in northern Australia
Invasive ants are among the greatest environmental, social and economic threats to Australia, potentially costing the nation more than $1 billion annually. However, knowledge of the basic biology of these pest species remains rudimentary, and many management operations have been unsuccessful.

Mites hitch lift in birds’ beaks
Nectar-eating Australian birds make clever choices about which flowers to raid. And so do the flower mites which hitch a ride in their nasal passages, according to zoologists Jolene Scoble and Assoc. Prof. Michael Clarke at La Trobe University in Melbourne.
Surviving in the city
Why do some plant and animal species thrive in the city while others disappear?
Most ecological studies are done in natural environments not in towns and cities so we lack information on urban ecology.
A team from Melbourne’s Royal Botanic Gardens is changing that.
Penguins hold missing pieces of evolutionary puzzle
Antarctica’s humble Adélie penguin is helping scientists shed new light on the process of evolution and may even hold the secret of how animals adapt to climate change.

Lake Mungo reveals ancient human adaptation to climate change
Aboriginal Elders from the Traditional Tribal Groups in the Willandra Lakes World Heritage Area are collaborating with researchers to produce the first integrated account of the history of human settlement, landscape evolution and past environmental change for Australia’s foremost ‘Ice Age’ archive.

The lighting revolution has only just begun
LED lighting is sweeping the world. It’s energy efficient, long lasting, and could save users billions of dollars worldwide and dramatically reduce carbon emissions. But it’s still a young technology. Much more efficient lights are on the way.

Building water sensitive cities
Annually, almost as much stormwater falls on Melbourne as its citizens use, but only a fraction is captured and reused. Billions of litres of stormwater literally go down the drain and into Port Phillip Bay, degrading the ecological health of Melbourne streams and the bay.
Invasion of the grasses
DNA barcodes could help farmers and conservationists identify wanted and unwanted grasses.
Identifying grasses is difficult especially when they’re not flowering. But identification is important. Australia’s agriculture and ecology are threatened by invading grasses, such as Chilean needle grass (Nassella neesiana) and serrated tussock (N. trichotoma). And efforts to re-introduce native grasses can be hampered if you can’t tell the grasses apart.
Womb of life
What if the very thing that assists a fetus to grow in the womb could also prevent disease in a fully grown adult?
Monash Institute of Medical Research scientists have discovered that stem cells from the womb have the potential to treat inflammatory diseases such as lung fibrosis and liver cirrhosis in both children and adults.
