Bionic ear pioneer wins the $50,000 CSL Florey Medal for 2011

Now Graeme Clark is looking for a better ear using his first recipient’s cochlear gift

Ceremony: 7 pm, 21 Nov, Mural Hall, Parliament House Canberra

Australian bionic ear pioneer Professor Graeme Clark will receive the CSL Florey Medal tonight in the presence of 90 of his peers at the 2011 Association of Australian Medical Research Institute’s annual dinner in the Mural Hall at Parliament House Canberra.

Over the past thirty years hundreds of thousands of people have had their lives transformed by Graeme Clark’s invention. Thirty-three years after Rod Saunders became the first recipient of Clark’s bionic ear, Graeme is returning to the laboratory to improve the bionic ear, and the new generation of bionic devices following it.

Today he announced that he will be joining NICTA, Australia’s national ICT Research Centre of Excellence, to help them close the gap between electronics and the brain – making better connections and enabling a bionic ear that would provide true hi-fi hearing.

And, he will bring to the laboratory precious brain and ear samples donated by Rod Saunders, the first recipient of the bionic ear. Rod died in 2007 and bequeathed his body to medical science.

In winning the CSL Florey Medal, Graeme joins an elite bunch of Australian medical researchers following in the footsteps of Howard Florey who developed penicillin.

They include:

  • Nobel Laureates Barry Marshall and Robin Warren, for discovering that bacteria cause stomach ulcers;
  • Jacques Miller, who unravelled the role of the thymus in the immune system;
  • Colin Masters, for his pivotal work on Alzheimer’s disease;
  • Peter Coleman, who unveiled the structure of the ‘flu virus, leading to the anti-’flu drug Relenza;
  • Ian Frazer, for the development of the vaccine against cervical cancer.

The medal has been presented every two years since 1998 by Australian Institute of Policy and Science (AIPS).

The prize money has doubled this year thanks to the support of CSL. “We deeply appreciate the support of CSL. This is a time when medical research needs champions, and with CSL’s help we are recognising and promoting those champions to all Australians and the next generation,” says Elektra Spathopoulos, AIPS executive director.

“Graeme Clark is a fitting winner,” says CSL’s Chief Scientist, Dr Andrew Cuthbertson. “Professor Clark had a big idea and took it through a tortuous scientific and regulatory path to create a device that has transformed the lives of people around the world. His ideas have seeded many other initiatives in bionics.”

Now 76, Graeme shows little sign of slowing down. “I don’t think I’m genetically engineered to wind down, but I’m trying hard, for my family’s sake.”

Tuesday: Sonya Pemberton nominated for National Press Club Excellence in Health award

Melbourne-based science writer and film-maker Sonya Pemberton has been nominated for a National Press Excellence in Health Journalism award to be announced at the National Press Club.

She was nominated for her film Immortal, which shows the astonishing discovery made by a team of scientists led by Australian-born Professor Elizabeth Blackburn: a key to unlimited life and endless youth in cells.

On Tuesday 22 November the award will be given out in Canberra, but Sonya is currently in Europe for her next project, which focuses on vaccination.

She’s looking at the measles epidemic sweeping France that started when just one 10-year old school girl brought the disease back from holidays to a cluster of low vaccination.

Wednesday: Australia Hears becomes Blamey & Saunders Hearing

Peter Blamey and Elaine Saunders, the scientists behind Australia’s new self-fitted digital hearing aids, have renamed their company to avoid confusion with other hearing aid suppliers.

The name change, to Blamey & Saunders Hearing, coincides with their move into bigger premises in East Melbourne, to accommodate more staff, more stock and a bigger audiology clinic. And they are now selling their hearing aid products under the IHearYou™ brand name.

Blamey & Saunders Hearing’s new name and new office are being launched officially by Michelle Gallaher, CEO of the BioMelbourne Network, on Wednesday 23 November.

Corals can sense what’s comingI

Australian scientists have thrown new light on the mechanism behind the mass death of corals worldwide as the Earth’s climate warms. A team of scientists from Townsville has shown that as sea water begins to warm a complex cascade of molecular signals is triggered leading up to the self-inflicted death of corals and their symbiotic algae .

Sunken islands found in Indian Ocean


In the remote waters of the Indian Ocean, west of Perth, scientists have discovered two sunken islands, almost the size of Tasmania, which were once part of the supercontinent Gondwana. The data collected could significantly change our understanding of the way in which India, Australia and Antarctica broke off from Gondwana.

Spinal cord treatment offers hope


Brisbane researchers have developed a promising new treatment for spinal cord injury in animals, which could eventually prevent paralysis in thousands of people worldwide every year. The treatment, which combined vascular endothelial and platelet-derived proteins, was applied to animals immediately after spinal cord injury, and evaluated after one and three month periods.

No such thing as empty space


An ingenious experiment in which tiny parcels of light, or photons, are produced out of empty space has confirmed a long-standing theory that a vacuum contains quantum fluctuations of energy. In a landmark result, an international team of researchers has demonstrated for the first time a strange phenomenon known as the dynamical Casimir effect, or DCE for short.

Mini-strokes provide health warning


Patients who suffer stroke-like attacks can have mortality rates 20 per cent higher than the general population, new research finds, leading to calls for better stroke prevention strategies for those who experience a transient ischemic attack (TIA). In one of the largest studies of its kind ever conducted, more than 20,000 adults hospitalised in New South Wales between 2000-2007 with a TIA were compared against the general population for mortality rates.

Stop signal discovered for skin cancer


A new understanding what stops a common form of skin cancer from developing could make new cancer treatments and prevention available to the public in five years. An international team of scientists led by Melbourne researchers has discovered a gene that helps protect the body from squamous cell cancer (SCC) of the skin. The Cancer Council estimates that two in three Australians will be diagnosed with skin cancer before the age of 70 with SCC being one of the most common forms.

Tiny gene. Big melanoma risk


Queensland medical researchers, as part of an international study, have found a variant in the MITF gene which can significantly increase the risk of melanoma. The MITF gene is responsible for regulating pigmentation and melanoma development, but this small mutation can have a large impact on melanoma risk. Individuals possessing this genetic variant have a 250% increased risk of developing melanoma – which is as significant to melanoma risk as traits such as having red hair, say the researchers.

Magnetic treatment improves stroke patients’ ability to communicate


Magnetic stimulation of the brain could help improve language skills of stroke survivors with aphasia, according to research in Queensland. Transcranial Magnetic Stimulation is a non-invasive method that seeks to target brain activity, with the intention of facilitating the reorganisation of brain regions to alter language behaviours. The treatment involves placing a coil on the head which uses electromagnetic induction to induce weak electric currents by means of a changing magnetic field.

Monitoring technology to help maintain seniors’ independence


Seniors should be able to continue living an independent lifestyle in the comfort of their own home thanks tonew in-home monitoring technology being trialled on selected Illawarra residents. The system provides vital information on the day to day wellbeing of seniors who choose to remain in their own homes by recording data based on energy consumption in the household. The daily routine of each household will be mapped; with the monitor sending out an alert should an irregularity appear.

Clothing, food and electricity impact most on water footprint


A new Melbourne study reveals that clothing, food and electricity are the three biggest culprits for a household’s high water usage. The indirect, or embodied, water usage of an entire household over 50 years – which includes the construction and maintenance of the house, all belongings, food, clothing and other consumable items, financial services, cars and holidays – is equivalent to filling 54 Olympic swimming pools. It represents 94% of a household’s water footprint.

Human activity pulling the plug on a vital carbon sink


Human activity is significantly weakening the ability of coastal ecosystems to dampen the impacts of rising CO2 levels, according to a new study by Sydney environmental scientists. The team has recommended that a high priority be placed on protecting and conserving seagrass, salt marsh and mangrove ecosystems.

Brain link with restless legs


Researchers have found that people with restless legs syndrome – a disorder that causes a powerful urge to move the legs, particularly at night – have reduced function in an area of the brain important for controlling movement. Preliminary results from a new study at Neuroscience Research Australia (NeuRA) suggest that people with this disorder have up to 80 per cent less function in this brain region compared with healthy people.

New light shed on world’s deadliest pandemic mystery


Queensland research into the world’s most deadly influenza pandemic in 1918 has shed light on a major medical mystery. The study examined US and Commonwealth military records and controversially suggests that the presence of two different viruses is the reason the second wave of the pandemic was so much deadlier. The conclusions highlight the importance of acquired immunity and the use of modern vaccinations.

Australia’s first fowl cholera vaccine


Australia’s first live vaccine for fowl cholera in chickens, recently registered and approved for sale, is the result of a breakthrough in bacterial modification by Monash University researchers. Highly contagious fowl cholera is a problem in all poultry-producing countries, particularly where the birds are intensively reared, and also due to organic and free-range practices. Treatment is very difficult due to the fast progression of the disease and so vaccination of layers and breeders, is considered a better option.

UQ researchers develop new method for studying gene activity


Researchers from UQ, Harvard University and RocheNimblegen Inc. have developed a new method for examining genetic information that reveals clues to understanding gene structure and activity in the body. The method allows researchers to delve further than ever before into the human genome. It involves combining existing gene capture techniques with state-of-the-art ‘deep sequencing’ technology. Deep sequencing enables millions of different DNA molecules to be read in parallel.
