Small urban ‘rain gardens’ are popping up all around Australia and Indonesia to keep waterways free from pollutants, stop flooding and erosion, and to grow food.
Although they may look similar to a normal garden, beneath the surface rain gardens are a sandwich of layers of sand, gravel, roots and microbes through which polluted water passes and clean water exits, which can then be used for irrigation or washing.
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.
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.

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.
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.
Malaria kills 500,000 people every year. And 90 per cent of those are children. Griffith University researchers are screening hundreds of thousands of compounds supplied by Japanese companies to find the right compound with activity against the malaria parasite.
Japan’s Global Health Innovative Technology Fund is supporting the research as part of their search for new ways to fight malaria.
“GHIT is a fund that invests in partnerships between Japanese and non-Japanese entities,” says BT Slingsby, the Executive Director of GHIT.
“Many of those entities are in Australia including The University of Melbourne, The Walter and Eliza Hall Institute, and Griffith University.”
“Currently we’re working with companies such as Daiichi-Sankyo, Takeda, Mitsubishi Tanabe, and Eisai,” says Griffith University’s Vicky Avery.
They bring those compounds to us. We then dispense them into plates which contain the parasite we’re trying to kill. After they’ve been incubated for a period of time we then look to see whether they’ve had an effect in killing the parasites.
“Once one defines a hit, usually it’s the pharmaceutical company that drives forward the further development of that compound to create a drug.
“This collaboration is fantastic in that it has three groups who complement each other,” Vicky says.
The Japanese pharma companies bring expertise in drug discovery and development. GHIT has managed to pull together significant funding from both global partners as well as the Japanese Government. And Griffith University brings the biology expertise.
