The long-term survival chances of patients with breast cancer plummet if the cancer recurs or spreads to other parts of the body in the process known as metastasis.

So the National Breast Cancer Foundation recently funded a five-year, $5 million National Collaborative Research Program to investigate metastasis and discover potential drugs to stop or slow it. The EMPathy Breast Cancer Network program was also charged with finding ways of diagnosing metastasis before it occurs. The research is highly dependent on the latest sequencing technology and demands the massive computer power and sophisticated data handling techniques of modern bioinformatics.

The technology used in your PC or PlayStation is also helping drive a revolution in radio astronomy—the replacement of custom-built hardware with flexible software and data solutions.
“Hardware solutions for radio astronomy have been evolving, but computer power has been evolving much faster,” says Matthew Bailes, from the Swinburne Centre for Astrophysics and Supercomputing. The Centre has developed software systems that are now used in Australia and overseas. Continue reading PlayStation graphics chips drive astronomy supercomputer→

Over aeons of time cosmic gas comes together, stars begin to form, supernovae explode, galaxies collide. And computational astronomers can watch it all unfold inside a supercomputer. That’s the kind of work post-doctoral fellows Rob Crain and Greg Poole are doing at the Swinburne Centre for Astrophysics and Supercomputing. Continue reading Supercomputers bring theory to life→
Researchers in the School of Geosciences at the University of Sydney have developed a computer package that lets scientists record and study the Earth over geological time.

Their GPlates software, which they describe as “Google Earth with a time-slider,” contains powerful tools for modelling geological processes. Yet it is simple enough to use in schools or at home, and is freely available. By combining data on continental motion, fossils and sediments, for example, scientists can analyse changes in geography, ocean currents and climate over geological time.

Every new technology brings opportunities and threats. Nanotechnology is no exception. It has the potential to create new materials that will dramatically improve drug delivery, medical diagnostics, clean and efficient energy, computing and more. But nanoparticles could also have significant health and environmental impacts.
