A cheap and simple material, using sulphur from petroleum industry waste and plant oils from the food industry, is being tested to clean up mercury pollution from soil and water.
The rubbery material will undergo field tests in 2017 in Australian mining and sugarcane sites, the latter of which use fungicides that contain mercury. The work is supported by funding from the National Environmental Science Programme’s emerging priorities funding.
“Our technology is about as simple as it can get: mix sulphur with plant oils and heat, then add the resulting material into the contaminated area,” says lead researcher Dr Justin Chalker, of Flinders University. Continue reading The sweet side of sulphur: cheap mercury clean-up
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.

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
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. Continue reading Converting body heat into useable electricity
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
A transparent, silk-derived implant that looks like a contact lens and can fix damaged eardrums is giving hope to millions who suffer from recurrent ear infections.
Creators of the device—from the Australian Research Council’s Future Fibres Research Hub and the Perth-based —secured funding to start human clinical trials with it in Australia in 2018.
The implant, called ClearDrum, is made from silk protein that forms a see-through scaffold on which cells can grow to close eardrum perforations. Continue reading Touch of silk to repair ruptured eardrums
A star-shaped, large 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
Saliva or blood tests may one day be used to detect when we’re too tired to drive or think clearly.
A team of scientists has found specific biological markers (biomarkers) linked to reduced alertness, including eye movement patterns, blood-based metabolites, chemiresistor signal responses and various speech parameters.
If these can be used to develop a test, they hope to see it on the road and in the workplace within the next two-to-five years. Continue reading Towards a portable test for tiredness
Switching off T cells before they begin to damage the nervous system is the basis of an Australian therapy for multiple sclerosis (MS), which is expected to begin clinical trials by the end of 2017.
Developed by researchers at Victoria University in western Melbourne and the University of Patras in Greece, it brings together peptides, or protein fragments, with a biochemical delivery system already shown to be effective in cancer vaccine clinical trials. Continue reading Turning off toxic T cells in MS clinical trial
A new index on digital inclusion is setting out a path for all Australians to get the vital benefits that come with internet access.
Information and communication technologies have become near-essential for everyday life, but many people in low income, remote and vulnerable communities can’t access them. Continue reading The dream to get every Australian connected online
