How Australia and India broke up—100 million years ago

Dr Joanne (Jo) Whittaker, Institute for Marine and Antarctic Studies, University of Tasmania, Hobart

Dr Joanne (Jo) Whittaker likes to solve jigsaw puzzles. Now this marine geoscientist is tackling the biggest puzzle on the planet—the formation of continents.
WithSDP_0059 the help of Australia’s national marine research vessels, and now her L’Oréal Fellowship, Jo is reconstructing how the Indian, Australian and Antarctic tectonic plates separated over the past 200 million years, forming the Indian Ocean and the continents as we see them today. This information will help us model climate change better, find new gas resources, and understand the dynamics of the land in which we live.

The piece of this jigsaw she is now working on centres on two underwater plateaux, the Batavia and Gulden Draak Knolls, towering about 3000 metres above the Perth Abyssal Plain (PAP), which is around 1600 kilometres off the coast of Geraldton in Western Australia. In November 2011, Jo’s team mapped and sampled rocks from both knolls. Based on the evidence so far, Jo says, it looks like they split from the margins of the moving Indian Plate about 100 million years ago.

When killing saves lives: our immune system at work

Dr Misty Jenkins, Peter MacCallum Cancer Centre, Melbourne

Misty-Jenkins-700x500Dr Misty Jenkins spends a lot of her time watching killers at work: the white blood cells of the body that eliminate infected and cancerous cells. She can already tell you a great deal about how they develop into assassins and arm themselves. Now with the support of her L’Oréal For Women in Science Fellowship Misty is exploring how they become efficient serial killers—killing one cancer cell in minutes and moving on to hunt down others. Her work will give us a greater understanding of our immune system and open the way to better manage T cells to defeat disease.

Misty’s career so far has been quite a journey for a girl from Ballarat. Along the way she been mentored by Nobel Prize-winning immunologist Prof Peter Doherty and become the first Indigenous Australian to attend either Oxford or Cambridge. Now working with Prof Joe Trapani as a National Health and Medical Research Council  (NHMRC) postdoctoral fellow in the Cancer Cell Death laboratory at the Peter MacCallum Cancer Centre in Melbourne, Misty has been awarded a $25,000 L’Oréal Australia and New Zealand For Women in Science Fellowship. She will use the money to further her study of what triggers T cells to detach themselves from their targets and seek additional prey.

Small devices to fight a big disease

Detection of dangerous water-borne pathogens will soon be much easier, thanks to advances using microfluidic systems developed at the Melbourne Centre for Nanofabrication (MCN), the Victorian node of the Australian National Fabrication Facility (ANFF).

Microfluidics deals with the control and manipulation of fluids in tiny, constrained volumes, in order to perform scientific tasks. The advantages in such systems centre around the cost and effort savings associated with miniaturisation and automation.

Made to order: printing of live cells

Surgeons may soon be able to regrow patients’ nerves, such as those in damaged spinal cords, using technology adapted from the type of inkjet printer most of us have connected to our computer at home.

Researchers at the ARC Centre of Excellence for Electromaterials Science (ACES), University of Wollongong (UOW) node in NSW, have spent the past three years developing the technology to print living human cells—nerve cells and muscle cells onto tiny biodegradable polymer scaffolds. They’ve also developed a special “ink” that carries the cells.

More efficient solar cells with quantum dots

The global race to develop high efficiency, low cost solar energy is fierce. And Baohua Jia and her colleagues are front runners.

Conventional solar cells are efficient, but thick and expensive. Baohua and her colleagues imagine a future when solar cells are so thin and cheap that city skyscrapers will be powered by a coating on their glass. But at present such thin-film solar cells are not efficient enough for general use.

Using her knowledge of nanotechnology and optics, Baohua and her colleagues have already created thin-film solar cells that are more than 20 per cent more efficient than those of her competitors. They have already lodged two patents.

But Baohua thinks she can do better. And that will be the focus of the work assisted by her $25,000 L’Oréal Australia & New Zealand For Women in Science Fellowship.

A new art form from nanotech

Science and art have combined to bring hand-drawn content for holographic TV and other 3D display technologies a step closer, thanks to research at the Australian National Fabrication Facility’s NSW node (ANFF-NSW) at the University of New South Wales (UNSW).

Unlike the traditional method of making a hologram—which involves reflecting a laser off a real object—the new technique simulates objects within computer software. In a recent test, a virtual, digital hologram file was produced and etched as a 3 mm-wide nanoscale pattern onto a glass plate using ANFF-NSW’s Electron Beam Lithography facility. When laser light was shone through the glass, a 3D hologram sprang into life.

Light work makes for a better drop

New Australian technology will enable real-time monitoring of wine throughout its fermentation and maturation process, reducing spoilage and improving quality.

The “Smart Bung” technology has been pioneered at the University of Adelaide by the Institute for Photonics & Advanced Sensing (IPAS) and the School of Agriculture, Food and Wine (SAFW). The work is led by Prof Tanya Monro, Director of IPAS.

An optical fibre sensor incorporated into the bung of a wine cask can detect substances that might cause the wine to spoil. The optical fibres have tiny holes that take up minute samples of the wine. The sensor shines light through the fibres to determine the concentration of certain important chemicals, such as hydrogen peroxide and sulphur dioxide—all without having to open the cask. The system will enable continuous, real-time cask-by-cask monitoring and an immediate response if problems are detected.

Micro muscles bend to the task

A breakthrough in the electroactive polymers used to make electrically controlled micro “artificial muscles” could be important for future drug delivery in the body, as well as a having a host of other applications.

The new research, conducted at the Australian National Fabrication Facility’s (ANFF) materials node at the University of Wollongong (UOW) in NSW has produced materials which, unlike earlier versions, do not need to be immersed in an electrolyte solution. They are self-sufficient and can even work in air. Continue reading Micro muscles bend to the task
