One of humanity’s biggest threats is also the smallest – bacteria. But now, researchers at RMIT in Australia have found a new method for killing these superbugs that they can’t resist – magnetic nanoparticles that physically tear them to shreds.

The quality of 3D-printed metal parts could soon improve, thanks to new research out of Australia. Scientists there have determined that the application of ultrasound boosts the strength of such items, by modifying their microstructure.

The 3D-printing of titanium-alloy objects does open up some intriguing possibilities. That said, the finished items aren't always as strong as they could be. New research suggests that adding copper to those alloys could make a big difference.

A team of Australian researchers has developed a novel early detection test for Parkinson’s disease based on a short series of drawing and writing tasks. The team is aiming to move through final trial stages and bring the new test to market by 2022.

Australian scientists have developed a stick-like tes device that users spit on to find out if they're at risk of heart disease.

Engineers have recently focused on trying to emulate the structure of the brain with artificial synapses. Now, a team of researchers have made a new artificial synapse design that works using a light-based biotechnology technique called optogenetics.

Capturing carbon from the air and sequestering it is emerging as a viable strategy, and now scientists have developed a new method to turn CO2 gas back into solid coal, that can then be buried, or even used for electronic components.

​When sewage sludge is processed at wastewater treatment plants, the leftover "biosolid" material is generally dried and set aside. While some of it ends up being used as fertilizer, much is often just stockpiled. Soon, however, it could find its way into eco-friendly fired-clay building bricks.

Fiber optics allows for ultra-fast communication systems, and more data can be crammed in by "twisting" the light. Now, Australian researchers have developed a device to decode beams that’s small enough to fit over the end of a fiber optic cable.

​While exposure to SOME sunlight is necessary, we all know that getting too much is not a good idea – among other things, it can cause sunburn, skin cancer and premature aging of the skin. With that in mind, a new paper wristband has been designed to let us know when to seek the shade.

​Titanium is very biocompatible, which is why it's so often used for medical implants. That said, chemical compounds in the metal sometimes do result in implants being rejected by the body. Scientists at RMIT University are attempting to address the problem, by coating such implants with diamonds.

​There are already "smart glass" windows that can be tinted to block the sun's hot rays, thus reducing the need to run air-conditioning systems. Such systems still require electricity, however. Now, scientists have developed a coating that allows existing glass to become smart … no power required.
