After two decades of research the first wave of nanotechnology consumer products are entering the marketplace in applications as diverse as catalysts, surface treatments for glass, cosmetics and drug delivery. But the properties that make them attractive to industry may also have unforeseen consequences. That worries Amanda Barnard, a physicist at The University of Melbourne.
“Many materials that are normally inactive—gold and silver, for example—become biologically active when the particles are just a few nanometres in size. So, if we are creating these new particles we need to understand how they will behave in the environment.”
Amanda believes she can create a theoretical framework that will allow the risk of nanoparticles to be determined in the computer—before the particle has even been made. She will use her L’Oréal Australia For Women in Science Fellowship to develop new computational tools to predict the behaviour of nanoparticles in the environment.

As a child, Natalie Borg tried to grow crystals. Two decades on, she is still growing crystals. But now she is analysing them with synchrotron light, to figure out how our bodies mount a rapid defence when we are attacked by viruses.
“The immune system is complex and is made up of many specialised types of cells and proteins. The key is to understand their function,” Natalie says.
To date, she’s been working as part of a successful team at Monash University. In 2007 her work on how our natural killer T cells recognise fats from invaders was published in Nature.
Now she’s setting up her own laboratory at Monash—a bold move but essential if her career is to grow. With the help of her L’Oréal Australia For Women in Science Fellowship, she will study key steps in our body’s early warning system against viral attack.
Erika Cretney is fascinated by the human immune system. “As we find out more about how it works, it seems to grow in complexity,” she says. “I’m not sure that we’ll ever know everything about it.”
Her interest lies in ferreting out the function of genes, proteins and cell types in the immune system, and identifying the roles they play. And with the help of her L’Oréal Australia For Women in Science Fellowship, she is pursuing a new target: a small group of T cells that play a role in controlling inflammation and auto-immune diseases.
The Fellowship will give her the freedom to promote her new field of study at international conferences and it will help with childcare costs as she balances a full-time research career with the needs of her young son. Continue reading Unravelling the immune system→
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.
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.
