The remains of volcanoes from billions of years ago are helping scientists identify both bygone continental boundaries and new places to find mineral resources in Australia.

Honey for your wounds?
The benefits of using medical-grade honey to treat and prevent infection in wounds has been confirmed by Sydney researchers.
Dr Nural Cokcetin tested more than 600 Australian honey samples and documented the antibacterial activity, which strongly corresponds to the levels of methylglyoxal (MGO), one of honey’s most active ingredients.
When boron nitride outshines gold and silver
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
Aussie kit detecting threat of toxic algal blooms
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
Using stars to overpower superbugs
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
Detection of cancer and PTSD
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.
Converting body heat into useable electricity
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.

Improving agriculture, together
A new approach to horticultural spraying could be the result of a collaboration between design students from Kyoto Institute of Technology and Swinburne University in Melbourne.
“Yanmar is a manufacturer of farm machinery, and they asked us to solve a big problem for grape-growers,” says Natsumi Takamatsu, a design student at Kyoto.
“What we developed was a sprayer to mitigate the drift of sprayed agricultural chemicals. Really it was the actual viticulturists when we interviewed them and they were saying things like ‘If only I had something like this.’”
“Australia and Japan enjoy the seasons at opposite times of the year so we can conduct field research in the vineyards all year,” says Yoshiro Ono from Kyoto Institute of Technology.
Harnessing the sun and improving agriculture
Mitsubishi Heavy Industries have built a pilot concentrated solar power plant in Yokohama. It uses CSIRO technology now being manufactured by South Australian company Heliostat SA.
“We’re making seven-and-a-half-metre square solar mirrors,” says David Linder-Patton, the CEO of Heliostat SA.
They focus the sun’s energy into a tower receiver that generates heat which can be used in industries such as steel manufacturing, brick processing and mineral refining.
The Mitsubishi plant will test their technology on receivers they have developed and also CSIRO’s suntracking technology and heliostat manufacturing.
“Working with companies the size of Mitsubishi helps us to get to industrial scale a lot quicker than we could do otherwise,” says David.
Making mining safer
In Western Australia’s Pilbara iron ore mines, a fleet of robot trucks are moving more than a billion tonnes of dirt and rock. The giant trucks carry 350 tonnes in every load. They’ve been developed over the past decade in partnership with Komatsu.
“Rio Tinto and Japan’s Komatsu came together to produce not just the robots but a technology that is immensely useful to Rio Tinto.
Putting those things together has produced a fantastic result,” says Tetsuji Ohashi, the CEO of Komatsu.
“Mining in the future is all about moving lots and lots of material more efficiently,” says Michael Gollschewski, the MD of Rio Tinto’s Pilbara mines.
“Today we’ve got controllers sitting in the operation centre in Perth, overseeing 72 autonomous trucks 1500 km away in the Pilbara across three different sites. It’s amazing,” he says.
Repairing teeth together
Across Japan teeth are being made stronger with chewing gum and other products using an ingredient discovered in Australian dairy milk.
Now an innovative Japanese company is taking the Australian discovery to dental surgeries around the world.
“Our discovery was based on milk, to develop a delivery system of calcium phosphate to make teeth stronger,” says Eric Reynolds, from The University of Melbourne.
Clinical trials of the chewing gum showed that it helps stop tooth decay and helps reverse early stages of tooth decay.
“The Recaldent chewing gum was very successful in Japan and the leading dental supply company in Japan, GC Corporation, then became interested in the technology.”
“We’ve developed materials for repair of tooth decay and damage but now we’re focusing on prevention and protection collaborating with Melbourne University,” says Satoshi Tosaki from GC Corporation.
“One of those products is a cream, in Australia it’s called Tooth Mousse, that’s sold to dentists to strengthen patients’ teeth and that’s now sold in more than 50 countries worldwide,” he says.
“I’ve really enjoyed working with GC because I’ve learnt a lot from them in terms of business. But I think the most gratifying thing is that their products actually help people, and substantially reduce the burden of oral disease,” Eric says.
