A University of Melbourne team has developed a device that uses nanoscale diamonds to measure the magnetic fields from a living cell’s atoms and molecules, with resolution a million times greater than current magnetic resonance imaging.

A malaria vaccine target

A vaccine is the holy grail of malaria control. Alan Cowman, of Melbourne’s Walter and Eliza Hall Institute, has discovered proteins that are key to the malaria parasite’s virulence, and therefore a potential vaccine target. He’s been able to weaken live parasites by manipulating their genes. It’s the culmination of over 20 years’ research into malaria and won Alan a $50,000 Victoria Prize.

Mundane passion anchors $20 billion industry

An engineer has credited a passion for the mundane as the driving force behind his geotechnical solutions that have influenced nearly all the oil and gas developments in north-west Western Australia.

Mark Randolph is providing engineering solutions to support offshore oil rigs.

The industry is expanding rapidly to meet the demand for natural gas in the growing Asian economies. Mark Randolph has contributed to anchoring the essential infrastructure as the industry moves offshore and into deep waters. He provides the analysis and design of piled foundations and solutions for offshore foundations, anchoring systems and pipelines.

Starch to save young lives

A fibre may help save millions of children in developing countries who die or who are left malnourished from diarrhoea each year.

Resistant starch in the diet may protect millions of children in developing countries from diarrhoea.

Graeme Young, AM, of Flinders University, is leading a global project that will test his theory that resistant starch increases zinc absorption in the body.

Putting off joint replacement

Advanced medical imaging has allowed Tasmanian scientists to trial new therapies for osteoarthritis and to potentially delay the need for joint-replacement surgery.

Graeme Jones and his team from the Menzies Research Institute used dual-energy X-ray absorptiometry to see what was happening to a joint’s internal structure as osteoarthritis developed, allowing them to spot changes long before a conventional X-ray could.

Clunies Ross

The 2013 ATSE Clunies Ross Award Winners follow in the footsteps of past winners such as Ian Frazer, inventor of the cervical cancer vaccine; Nobel laureate Barry Marshall, who discovered the bacteria that causes stomach ulcers; Fiona Wood, inventor of spray-on skin; and Martin Green and Stuart Wenham, international leaders in silicon cell technology.

The Australian Academy of Science recognised five individuals for their career achievements in 2013.

Tracking the spread of deadly diseases

Dr Kathryn (Kat) Holt, Bio21 Institute, The University of Melbourne

Kathryn-Holt-700x500-2Kat Holt is using genetics, maths and supercomputers to study the whole genome of deadly bacteria and work out how they spread. Studying a typhoid epidemic in Kathmandu, she found that it didn’t spread in the way we thought epidemics did. Her research, published in Nature Genetics, will change how we go about responding to epidemics.

With the support of her L’Oréal For Women in Science Fellowship, Kat will be using the same techniques to understand how antibiotic-resistant bacteria spread in Melbourne hospitals. Are people catching these superbugs in hospital, or are they bringing the bugs into hospital with them? Can we give the intensive care clinicians early warning of a drug-resistant bacteria in their patients?

Kathryn (Kat) has been a pioneer ever since she became the first student at the University of Western Australia to undertake an honours year in the then-fledgling area of bioinformatics.

Kat ventured across the Nullarbor to the other side of Australia—to the Walter and Eliza Hall Institute of Medical Research in Melbourne—where she sought advice from bioinformatics guru Prof Terry Speed. As a result, she ended up as a doctoral student at the world renowned Sanger Institute at the University of Cambridge, one of the homes of the human genome project.
