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?
There’s still life in lead batteries. East Penn Manufacturing operates the largest single-site, lead-acid battery manufacturing facility in the world in Berks County, Pennsylvania.
They argue that their new lead batteries are 99 per cent recyclable and ideal for large-scale storage.
To prove it, they’re developing a 3MW power storage system using the UltraBattery technology invented by Australia’s CSIRO.
By combining lead-acid technology with a supercapacitor, the UltraBattery not only charges and discharges rapidly, but lasts four to five times longer than an ordinary battery.
Almost all matter we can see and touch is made up of the protons and neutrons. But what are protons and neutrons composed of? The simple answer is quarks, of which there are six distinct kinds, held together by gluons.
The ‘strong force’ carried by gluons is about 100 times stronger than electromagnetism, which governs the interactions of atoms. It’s a major focus of the ARC Special Research Centre for the Subatomic Structure of Matter (CSSM).
Established 20 years ago at the University of Adelaide, the Centre is at the international forefront of investigating the ramifications of quantum chromodynamics (QCD), the theory which describes the strong force interactions that are fundamental to how our world works.

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.
This allows them to work with many leukaemia types simultaneously, providing a cheaper, faster and more accurate model of the leukaemia. Continue reading Improving survival for patients with acute leukaemia
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.

Ultra-thin boron nitride outshines gold and silver when used to detect contaminants in smart sensing technology.
It is 100 times more effective at detecting dangerous materials in our food and environment than noble metals.
Traditionally, detection surfaces of these devices have been made using gold and silver. But covering these metals with a microscopically thin layer of boron nitride greatly enhances their performance.
The findings are by a team from Deakin University’s Institute for Frontier Materials, Japan’s National Institute for Materials Science and China’s Wenzhou University. Continue reading When boron nitride outshines gold and silver
Toxic algal blooms can now be detected up to two weeks before they become a serious health hazard, thanks to an early warning system developed through an Australian university-industry partnership. Continue reading Aussie kit detecting threat of toxic algal blooms
A large, star-shaped molecule is being harnessed by a University of Melbourne team to kill superbugs.
Professor Greg Qiao and his colleagues from the Melbourne School of Engineering have created a polymer that kills antibiotic-resistant bacteria by ripping apart their cell walls. Continue reading Using stars to overpower superbugs
By 2020, multiple sites worldwide will be trialing a non-invasive test for post-traumatic stress disorder (PTSD). The machine can determine if soldiers and emergency workers are prone to the disorder, and if so, they may be rested and not immediately deployed again.

Imagine if your exercise clothes could generate enough electricity to power your workout gadgets. This could be a reality in a few years with the development of a flexible, self-charging, non-leaky battery (or thermocell) that could convert body heat into power for devices such as fitness trackers.
