Fresh Science helps Australian early-career researchers find their story and their voice.
Over the past 20 years Fresh Science has trained and empowered more than 500 future leaders in science to engage with the community, media, government and industry.
In 2016, we chose 60 researchers around the country, trained them, and gave them the chance to present their science in pubs, school talks and to the media. Here are a few of their stories.
Heart attacks, cancers, mental disorders, diabetes, and other non-communicable diseases (NCDs) are on the rise in Indonesia and Australia. In 2007 they caused 60 per cent of Indonesian deaths; by 2014 this had risen to more than 70 per cent.
NCDs also account for over 90 per cent of Australian deaths. More than half the country’s adults are considered overweight or obese and a 2014 study found Australia’s obesity rate was rising faster than anywhere else in the world.

More than 1.2 million Australians have an autoimmune disease. But any two people may experience it very differently, even if their disease has the same name.
Unlike infectious diseases, autoimmune diseases are not passed from person to person. They are our bodies fighting themselves, making every person’s disease unique.
“A lot of clinical trials fail as they treat all patients with a certain ‘disease’ as one big group,” says Professor Carola Vinuesa, from the National Health and Medical Research Council Centre for Research Excellence in Personalised Immunology at The Australian National University.

The researchers found that a father’s high-fat diet could change the molecular make-up of his sperm, leading to obesity and diabetes-like symptoms in two generations of offspring.
“With obese fathers, changes in the sperm’s microRNA molecules are linked with programming the embryo for obesity or metabolic disease later in life,” says Tod Fullston, the study’s lead author and an NHMRC Peter Doherty Fellow with the University of Adelaide’s Robinson Research Institute.
The Australian Academy of Science recognised five individuals for their career achievements in 2013.
The patented “lab-on-a-chip” and accompanying control system has attracted considerable interest from pharmaceutical companies, according to co-inventor Dr Greg Sheard of the Department of Mechanical and Aerospace Engineering. Continue reading Health check for live cells
Each year we identify early-career scientists with a discovery and bring them to Melbourne for a communication boot camp. Here are some of their stories.

Print your own lasers, lights and TV screens
Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have developed liquid inks based on quantum dots that can be used to print such devices and in the first demonstration of their technology have produced tiny lasers. Quantum dots are made of semiconductor material grown as nanometre-sized crystals, around a millionth of a millimetre in diameter. The laser colour they produce can be selectively tuned by varying their size.
High tech cling wraps that ‘sieve out’ carbon dioxide from waste gases can help save the world, says Melbourne University chemical engineer, Colin Scholes who developed the technology. The membranes can be fitted to existing chimneys where they capture CO2 for removal and storage. Not only are the new membranes efficient, they are also relatively cheap to produce. They are already being tested on brown coal power stations in Victoria’s La Trobe Valley, Colin says. “We are hoping these membranes will cut emissions from power stations by up to 90 per cent.”
Victorian scientists have discovered a milk protein with the potential to treat metabolic syndrome and chronic muscular and bone diseases.
The protein, when given daily to mice, caused them not only to build more muscle but also to want to exercise. The findings also showed an increase in muscle in mice not given exercise.
Why do we get fat? What’s the link between obesity, diabetes and hypertension? Can we break the link? These are critical questions around the world. Prof. Michael Cowley may have the answers.
He’s shown how our brains manage our consumption and storage of fat and sugar and how that can go wrong. He’s created a biotech company that’s trialling four obesity treatments.
