When it comes to systems for cleaning up marine oil spills, most of them simply float in place, waiting for the oil to come to them. A new robot, however, could proactively move through oil slicks – and it's inspired by both a dolphin and a sea urchin.

Giant solidified masses of fat, grease, and other waste threaten to clog sewer lines and cause huge spillages in cities worldwide. Researchers at RMIT have developed two novel ways to prevent these blocks of waste from forming.

Researchers in Australia have developed a titanium alloy that's 30% cheaper to produce than standard titanium, and is stronger and more ductile than other titanium alloys.

Researchers at Australia's RMIT University have devised a simple and clever contraption that could make drinking water available in disaster-stricken areas, by pulling it out of thin air.

Deep-sea sponges have a secret: their light lattice-like forms are astonishingly stiff and strong. Inspired by these creatures, RMIT researchers have developed a new structure to make significantly stronger materials for more durable buildings.

Tubular structures that fold flat for storage may not take up much room in that form, but they also tend not to be very strong when deployed. That isn't a problem with an experimental new type of tube, that's inspired by both origami and bamboo.

In a world first, the researchers who used waste coffee grounds to make concrete that’s 30% stronger are putting their innovative material to the test by laying sidewalks made of the stuff to see how it fares when it's subjected to foot traffic.

Bricks made of discarded glass and recycling-waste ash have been shown to insulate better than regular bricks, while also requiring less energy to produce. And of course, they additionally use materials which would otherwise end up in landfills.

While there are already clothing materials that help keep wearers cool simply by allowing heat to escape, an experimental new fabric coating goes a step further. Utilizing a whole bunch of nanodiamonds, it actually draws heat away from the body.

3D-printed concrete structures are claimed to be faster and cheaper to build than their traditional counterparts, but they're not always as strong. That problem may soon be solved by adding a pinch of graphene oxide, which could also be used to detect cracks.

Cybersecurity is a growing concern as more critical infrastructure can be exposed to hacks. Now Australian engineers have developed and demonstrated a new technique called “ineffable cryptography,” which treats keys like the Coca-Cola secret formula.

This year's Australian national Dyson Award winner tells us more about the bolt-on REVR retrofit kit he's developing, that aims to convert ICE cars to practical, efficient hybrids for less than US$3,200, taking less than a day to install.
