Breath test for malaria is in the air

At present, diagnosing malaria can be a difficult process involving powerful microscopes and careful scanning of blood samples for tiny parasites in a technique discovered in 1880. But a more accessible method may be in the works. A team of Australian scientists has discovered that certain chemicals are present and can be detected in the breath of sufferers, raising the possibility of a cheap breath test to diagnose the deadly disease.

Researchers create world's first 3D-printed jet engines

Working with colleagues from Deakin University and CSIRO (Commonwealth Scientific and Industrial Research Organisation), researchers from Australia's Monash University have created the world's first 3D-printed jet engine. While they were at it, they created the world's second one, too. One of them is currently on display at the International Air Show in Avalon, Australia, while the other can be seen at the headquarters of French aerospace company Microturbo, in Toulouse.Read More

Autonomous mini helicopters hunt down invasive weeds from the air

The sheer density of the rainforests in Australia's far-north creates a slight problem for local conservationists. With incursions by invasive plants posing a threat to the native flora, inaccessibility for people makes it a difficult and time-consuming task to monitor the region. Now researchers from the CSIRO have developed two mini helicopters capable of hunting down the dangerous weeds from the air, significantly reducing the resources needed to preserve local plant life.

Wastewater that cleans itself results in more water, less sludge

Using wastewater to clean itself is the premise of new Australian technology that relies on the formation of compounds called hydrotalicites, and which results in less sludge than traditional water treatment with lime. In one test in Australia, the equivalent of 20 Olympic-sized swimming pools of wastewater were treated, with final sludge reductions of up to 90 percent. Read More

CSIRO sets world record in generating "supercritical" steam using solar power

Researchers at Australia's CSIRO have claimed a world record for the highest temperatures ever achieved using solar energy to generate "supercritical" steam at its solar thermal test plant in Newcastle, Australia. Featuring more than 600 directional mirrors (heliostats) directed at two towers housing solar receivers and turbines, the researchers produced the steam at a pressure of 23.5 MPa (3400 psi) and 570° C (1,058° F).

Handheld device detects and analyzes soil contamination within seconds

Contamination of soil from petroleum spills is an ongoing problem that threatens to adversely affect the environment and the health of the people in it, so rapid testing of sites is a pressing issue. However, with laboratory samples and results requiring at least a number of days turn around, particularly in remote locations, rapid analysis is not usually possible. RemScan is a self-contained, hand-held hydrocarbon contamination testing device designed to address this problem. Recently released on the US market, the device is capable of testing many hundred samples a day, providing data on the spot, within seconds, and completely without the need of a laboratory.

"We Feel" tool uses Twitter to provide real-time view of world's emotions

A new online tool aims to create a real-time emotional map of how people all over the world feel, from analyzing how cheerful or depressed different countries might be, to how budget cuts or other news might hit people emotionally. Called "We Feel," the tool analyzes 32,000 tweets a minute to monitor people's collective mood swings and how their emotions fluctuate over time globally. Read More
