Fresh Science
Fresh Science is a national competition that has been helping early-career researchers find, and then share their stories of discovery for the past 18 years.
Taking young researchers with no media experience and turning them into spokespeople for science, Fresh Science gives its finalists a taste of life in the limelight, with a day of media training and a public event in their home state.
In 2015 Fresh Science ran in every mainland state, with 61 Fresh Scientists in six state events, and seven public events bringing Fresh Science to around 1000 members of the public.

And researchers need Perth men for a study to find out why
Monday 23 June 2014
Media call 9-10am AWST at Edith Cowan University Mount Lawley Campus with researchers and patients.
Perth researchers have shown that twice-weekly exercise can improve sexual function in prostate cancer patients by 50 per cent.
Now, they’re calling on Perth men to participate in a new study to find out why exercise works, and how effective it can be on a broader range of patients.
One in six Australian men will be diagnosed with prostate cancer, and 90 per cent of them will report some form of sexual dysfunction during or after their treatment.
“Men think about sex a lot – on average, every 45 minutes which is more often than they think about food or sleep,” says Dr Prue Cormie, a senior research fellow at Edith Cowan University. “So it’s not surprising that sexual dysfunction is the most frequently identified issue of importance among prostate cancer survivors.”
Last year, Prue and her colleagues at the Edith Cowan University Health and Wellness Institute put a group of men with prostate cancer through a supervised exercise program involving twice-weekly group-based sessions of resistance exercise such as weight lifting, and aerobic exercises including walking and cycling.

Lighter-weight, fuel-efficient cars may be closer to reality thanks to Geelong researchers who are giving carbon fibre the gripping power it needs to be able to stand up to impacts from motorists.
High-performance vehicles already use carbon fibre – a high-strength lightweight material that can be moulded into complex shapes – to make cars lighter, more fuel-efficient and faster.
But although strong, carbon fibre is prone to damage from sudden impact. And unlike metal, it can’t be repaired – only replaced.
This factor has limited the material’s uptake by the wider automotive industry, as the common bingle would end up costing motorists a lot more to fix.
Ms Linden Servinis, a PhD student at Deakin University, and her colleagues have developed a treatment for carbon fibre that makes it 16% stronger by forming extra chemical ‘arms’ that grip onto its surroundings, allowing the material to withstand greater impacts. [continue reading…]
But researchers have to teach yeast to make it
Thursday 5 June 2014
Queensland researchers are persuading baker’s yeast to produce orange-flavoured renewable jet fuel from sugar.
Mr Timothy Brennan and his colleagues at the University of Queensland’s Australian Institute for Bioengineering and Nanotechnology have helped genetically-engineered yeast to evolve to make an oil called limonene, which is found naturally in lemons and oranges, and also happens to be an efficient jet fuel.
They’ve worked out how to get the yeast to make more oil without killing itself in the process.
It’s an important step in scaling up biofuel production so that it can become a serious alternative to traditional fossil fuels. [continue reading…]

Scientist available for interview in Perth on Tuesday 3 June
Dr Francis Torres, a physicist at the University of Western Australia, has developed the mirror device at the heart of a new amplifier technology, which uses an interaction between a high-powered laser and mirror motion to magnify subtle metal, temperature and biological vibrations so they are more easily detected.
“Our idea is to connect the sensors in existing space exploration tools to our amplifier so they can look deeper underground and find smaller and hard-to-find targets such as hidden mineral deposits, water or other bacterial life,” says Francis, who developed the resonator mirror as part of his PhD.
According to Francis, the amplifier technology could also enhance the detection sensitivity of Earth exploration tools and medical sensors.

Vision: laboratories, close-up photos of the worms, footage of Michael’s talk
Cairns researchers have discovered a wound-healing and cancer-causing hormone in the spit of a liver worm that lives in over nine million people and infects adventurous Australian tourists. The Southeast Asian liver fluke munches through the liver repairing the damage as it goes. But after many years of infection it can cause liver cancer and kills 20,000 people each year in Thailand alone.
Now James Cook University researcher Dr Michael Smout has found that a protein in the spit also sends wound-healing messages.
In 2010 James Cook University researchers discovered that the worm spit was promoting cell growth and wound repair. Then in 2012 Dr Michael Smout discovered a growth hormone in the spit, showed it was responsible both for the repair and in part for the cancer, and that it promotes wound-healing. He hopes that the work will lead both to new wound-healing compounds, and to a vaccine against the worm.
The discovery received no public attention at the time. But now its discoverer, Dr Michael Smout, is presenting the work publically for the first time thanks to FameLab Australia. He won the Australian final two weeks ago in Perth using a teddy bear to assist in his talk. He flies to the International FameLab final in the UK on Friday to represent Australia.

Congratulations to Dr Michael Smout from James Cook University for taking out Australia’s first FameLab competition on Tuesday night in Fremantle, WA.
Michael and his research story on cancer-causing liver worms will be heading to the UK in June to represent Australia at the International FameLab competition held at the Times Cheltenham Science Festival.
He’ll be needing some extra luggage allowance to take his props with him.
Congratulations to all the finalists, and to the runner-up Tim Brennan from The University of Queensland.
You’ll be hearing more about Michael’s work and other Fresh Science stories in the coming weeks.

A simple and affordable ‘jetlag’ skin patch could help prevent deaths and disabilities of two million babies worldwide each year by reducing brain damage caused by low oxygen during birth.
Monash University PhD student James Aridas and his colleagues at MIMR-PHI Institute’s Ritchie Centre have found that melatonin patches, commonly used to treat jetlag in the US, can reduce damaging free radicals and subsequent brain cell death when they are administered in the hours after birth asphyxia has occurred.
The discovery could help change the fate of around 300 Australian babies who develop disabilities and neurodevelopmental disorders after birth asphyxia each year, as well as that of millions of babies in developing countries where treatment is almost non-existent.

Maths meets Carlton, AFL fights ACL
AFL knee injuries could be dramatically reduced if physiotherapists paid more attention to ankles, a Melbourne mechanical engineer has found. He is now trialling the mathematical models to help Carlton Football Club predict and screen for players at most risk of knee injuries.
Hossein Mokhtarzadeh has demonstrated that the ankle is key to preventing knee injuries that cost the Australian football codes tens of millions of dollars a year. As a University of Melbourne post-doctoral fellow at the Australian Institute for Musculoskeletal Science, Hossein is hoping to expand his work into protecting the anterior cruciate ligament (ACL) against injury by developing exercises to strengthen critical muscles supporting the ankle joint. He also has a vision for a mechanical bracing system for those who may not be able to train their muscles to a sufficient level.

Sydney sea squirts show that there’s more to fertilization and IVF than we thought
For sea squirts the key to a long and happy life is to be fertilized not by a fast sperm, but by one that stands the test of time, Dr Angela Crean, from the Evolution and Ecology Research Centre at the University of NSW, has found.
And her discovery, published in PLoS, also shows for the first time that the influence of sperm extends well beyond the moment of conception. If further studies demonstrate the same effects in human sperm, the finding will change some of the assumptions used in IVF practice.

Trial of treatment underway in Perth
Perth researchers are planning to end the sleepless nights that families face when ear infections strike and won’t go away. Their research could reduce the need for antibiotics and surgery, and help tackle hearing loss in indigenous communities.
Dr Ruth Thornton and her research team at the University of Western Australia have discovered that sticky nets of DNA hide the bacteria in the ears of kids with recurrent middle-ear infections, where they evade antibiotic treatment by creating impenetrable slimy biofilms.

Safeguarding an important food crop—and the world’s beer supply
- On-site – farmers’ crop of barley infected with leaf rust
- Lee Hickey, University of Queensland geneticist and John Agnew, Chair of the Northern Region Barley Advisory Committee will be available for comment.
An international study led by a Queensland scientist has found a way to better safeguard an important food crop—and the world’s beer supply.
The study, led by University of Queensland geneticist Dr Lee Hickey, successfully identified a gene that protects barley against leaf rust – a disease that hit Queensland farmers in 2010 and could destroy almost a third of the national crop.

Despite the claims of some, commercially viable fuels from algae have not yet been developed. But newly trialled native algae species provide real hope, a Queensland scientist has found.
Dr Evan Stephens and the team at the University of Queensland’s Institute for Molecular Bioscience, in collaboration with Germany’s Bielefeld University and Karlsruhe Institute of Technology, have identified fast-growing and hardy microscopic algae that could prove the key to cheaper and more efficient production of the alternative fuel.
With the help of these native species, Australia could potentially become an oil exporter like Middle East by devoting just 1% of its land to algae farms.

The discovery of a link between a specific gene and ageing in a species of worm could reveal valuable lessons for the treatment of Alzheimer’s disease.
Low levels of the protein generated from the gene known as ‘tau’—also present in humans—not only hastens age-related changes in the brain of the worm, but also shortens the worm’s life, Sydney University PhD candidate Yee Lian Chew has found.

Two tiny fossils are prompting an overhaul of theories about marsupial evolution after they revealed unexpected links to South America – and possibly Africa.
One of the fossils, found at the Tingamarra site in south-eastern Queensland, is a 55 million-year-old ankle bone from a mouse-sized marsupial previously known only from South America. The second is a tooth, which derives from a formerly unknown species that shows similarities to fossils found in South America and, surprisingly, North Africa.

Marsupial bones and worms’ brains
At day two of Fresh Science, meet two researchers from Sydney
Marsupial fossils the size of a grain of sand reveal unexpected links to South America – and possibly North Africa.
Two tiny fossils are set to overturn the conventional theory about the evolution of marsupials, which holds that there was a single migration from the part of the Gondwana ‘supercontinent’ that became South America to the part that became Australia.

Melbourne researchers have invented and patented a way of detecting and locating potential electrical faults along large stretches of power line before they occur.
The invention was inspired by a boyhood interest in electric fishes, such as the black ghost knifefish.
The patented detection system, already being employed by local electricity companies, could help prevent the major discharges that lead to sparking and blackouts, says Dr. Alexe Bojovschi, a post-doctoral fellow in electrical and computer engineering at RMIT University.

Asthma inhalers could soon become much more effective, thanks to a clever new way of making the particles they deliver invented by a Melbourne chemical engineer and his team.
Current puffer designs and typical size ranges of particles mean a large portion of the medication propelled into a patient’s throat remains there. Only a fraction reaches the lungs.
