Climate change will impose a complex web of threats and interactions on the plants and animals living in the ice-free areas of Antarctica.
Increased temperatures may promote growth and reproduction, but may also contribute to drought and associated effects. These scenarios are explored in a new book, Trends in Antarctic Terrestrial and Limnetic Ecosystems: Antarctica as a Global Indicator, co-edited by Australian Antarctic Division biologist, Dr. Dana Bergstrom.
The extreme weather conditions that can turn an already dangerous bushfire into an explosive firestorm can now be better predicted, thanks to the work of a 30-year veteran of the Bureau of Meteorology.

Predictive mineral exploration by Australian scientists has given local mining companies a powerful edge in the hotly competitive world gold market. Instead of pouring money – and lots of it – into the ground in the quest for undiscovered mineral deposits: often coming up empty.
Bureau of Meteorology Research Centre climate scientists believe they have part of the answer to significant declines in Australian regional rainfall and subsequent stream flow since the 1970s.

On Mondays, Jenny Gunton sees diabetes patients at Sydney’s Westmead Hospital. And from Tuesday to Friday, she heads up a diabetes research laboratory at the Garvan Institute of Medical Research. She’s also the mother of two-and-a-half-year-old “Action Boy”.
Gunton is one of a growing band of physician-scientists. “It’s not a financially sensible decision, but I enjoy it,” says Gunton. “It’s also a better way for me to ask questions and attempt to answer them. And in that way, I help my patients.”
And now, with the help of her L’ORÉAL Australia For Women In Science Fellowship she will be exploring the link between Vitamin D and diabetes.
Black holes are some of the most bizarre objects in the universe. They can have as much mass as a billion stars combined. How did they form and how did they get so big?
“What are they doing to the galaxies in which they live?” asks Dr Ilana Feain of the CSIRO’s Australia Telescope National Facility.
This is one of the biggest questions facing astronomers in the 21st Century. The 29-year-old astronomer will use her L’ORÉAL Australia For Women In Science Fellowship in her quest for an answer to this question.
And she is enlisting two Australian girls’ schools to contribute to a 24/7 program to observe a ‘nanoquasar’ and its associated black hole some billion billion kilometres from Earth. Continue reading School girls join study to understand black holes and the birth of stars
Sarah Pryke has always had an eye for the shape, colour and movement of animals. After growing up surrounded by wildlife in a remote rural area of South Africa, she was employed as an illustrator by the local museum while studying for her science degree at the University of Natal.
Now, as a post-doctoral fellow of the at Macquarie University in Sydney, she is working in the Kimberleys investigating the impact of colour on the behaviour of the Gouldian finch, a small, dazzling bird of Australia’s tropical savannah.
With the help of her L’ORÉAL Australia For Women In Science Fellowship she plans to get a better understanding of their mating success – information that could be crucial to the survival of these endangered birds. Continue reading Life and love amongst the finches: Aggressive redheads win the best nest sites, but can the Gouldian finches survive?
When Catriona Bradshaw volunteered as a visiting medical officer in sexual health and HIV medicine at an African hospital, it was a turning point that confirmed her career choice – in sexual health.
Now, with the help of her L’ORÉAL Australia For Women In Science Fellowship, Bradshaw plans to clear up confusion about a common genital infection of women – bacterial vaginosis.
She suspects that bacterial vaginosis may be sexually transmitted. By studying the spread of the disease in young women she plans to determine if this is the case.
She hopes that her work will lead to improved treatment regimes – benefiting women in the West and in developing countries.
