Professor Mark Kendall is planning to dispatch the 160-year-old needle and syringe to history. He’s invented a new vaccine technology that’s painless, uses a fraction of the dose, puts the vaccine just under the skin, and doesn’t require a fridge.
The Nanopatch is a 1 cm square piece of silicon with 20,000 microscopic needles engineered on one side. Coat the needles with dry vaccine, push it gently but firmly against the skin, and the vaccine is delivered just under the outer layer of skin.
It’s a technology he invented in response to a call from the Bill and Melinda Gates Foundation seeking ideas for delivery of vaccines in developing countries—where it’s a challenge to keep conventional wet vaccines cold to the point of delivery.
The idea that long-term memory might be stored in our brain’s DNA is being tested by Professor Geoff Faulkner, using brains affected by Alzheimer’s.
Geoff has already shown that the DNA in our brains is different to the DNA in the rest of our bodies and that it changes as we learn. He’s proposing that these changes are associated with how we store our long-term memories.
More recently, he’s linked these differences to the function of genes in the hippocampus, the part of the brain that controls memory and spatial navigation, and has been implicated in memory loss with ageing, schizophrenia and Alzheimer’s disease. Continue reading Are memories stored in DNA?→
Today, 85 per cent of children with leukaemia can be cured, but the outlook for patients over 60 is bleak. Only 10 per cent survive beyond one year as their cancer adapts to weather the storm of standard chemotherapy treatments. Associate Professor Steven Lane wants to change that outlook.
Steven and his team at the QIMR Berghofer Medical Research Institute have developed a method to rapidly profile the genetics of different leukaemia types—of which there are hundreds—and model them in the lab.
Australian and American researchers and businesses are partnering to bring new manufacturing technologies to market
Paint fit for a Dreamliner
Next time you board a new Boeing Dreamliner, take note of its Australian paint.
Developed by researchers at CSIRO, Australia’s national science agency, ‘Paintbond’ has now been adopted across the entire Boeing aircraft fleet, and more than 1,000 aircraft have been re-coated using the technology so far.
Why is it better? The new spray-on topcoat paint technology saves time, reduces the impact on the environment, and is safer to use.
Perth researchers help Chevron keep oil and gas flowing smoothly
Out in the Gulf of Mexico Chevron are operating a $7.5 billion platform that’s recovering oil and gas from two-kilometre-deep ocean.
It’s the largest and deepest operation in the Gulf, with over 146km of pipeline bringing oil and gas to refineries.
But pipelines operating at extreme depths in cold water and crushing pressure are prone to blockage. University of Western Australia researchers are helping Chevron keep oil and gas flowing through deep-water pipes.
The conditions have been right for Zika virus to spread during the warmer months of past years in Townsville, Cairns and Rockhampton, according to research led by the Australian Red Cross Blood Service.
Using temperature data from January 2015 to December 2016, the team modelled the ability of mosquitoes to spread the virus in four Queensland cities. Brisbane (the fourth city) was the only site where the risk was low.
“If locations experience outbreaks of dengue, the conditions would also be right for outbreaks of Zika,” says lead researcher Dr Elvina Viennet.
The findings emphasise the need for imported cases to be reported immediately, Elvina says.
Seagrass meadows provide food and habitat for everything from dugongs and birds to fish and tiny crabs.
Globally we’re losing over 100 sq. km per year due to dredging, coastal developments and runoff. That’s bad news for the animals they support, and bad news for us too, as seagrass supports healthy coastal fisheries as well as acting as a carbon store.
To see how seagrass can be given a fighting chance, Dr Paul Wu at the ARC Centre of Excellence for Mathematical and Statistical Frontiers and collaborators have put an extended modelling technique to new use, predicting seagrass health and suggests how some modified human activities could reduce the damage.
Professor Perry Bartlett is putting people with dementia on treadmills.
He has already reversed dementia and recovered spatial memories in mice through exercise. And in 2016 he and colleagues at The University of Queensland will begin clinical trials to see if exercise will have the same impact in people with dementia. Then he’ll look at depression.
Underpinning these projects is the idea that the brain is constantly changing; and that learning, memory, mood, and many other brain functions are in part regulated by the production of new neurons.
