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.

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.

Building water sensitive cities

water4a_300x180 Staff in a Monash University-led project, called Water Sensitive Cities, believe the time is right for a bold idea that could produce 20 to 30 per cent of Melbourne’s future water needs.

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

Womb stem cells could help regenerate a diseased liver.
Womb stem cells could help regenerate a diseased liver.

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.

Dr Marnie Blewitt wants to know how a human being is made: how does a single fertilised egg develop into an adult with millions of cells performing a myriad of different functions.

“How does a cell know which of its 30,000 or so genes should be active and which should be dormant?” says Marnie, a researcher at the Walter and Eliza Hall Institute of Medical Research.

Two million containers—but how many pests?

Balancing the risks and benefits of trade and pests.
Balancing the risks and benefits of trade and pests.

Every visitor to Australia quickly learns that we take quarantine seriously. Our country is free of many pests, weeds and diseases that are widespread overseas. Our relative disease-freedom is good news for our people, for agriculture and for the environment.

Visitors’ luggage is screened at the airports. But what about the two million shipping containers that enter Australia each year? How do we strike a balance between open trade and quarantine?

Victorian scientists have discovered a milk protein with the potential to treat metabolic syndrome and chronic muscular and bone diseases.

The protein, when given daily to mice, caused them not only to build more muscle but also to want to exercise. The findings also showed an increase in muscle in mice not given exercise.
