A passenger jet could one day fly halfway around the world in just a few hours. That’s the goal of the High-speed Experimental Fly project (HEXAFLY): going beyond the supersonic realm pioneered by the now-defunct Concorde to reach hypersonic speeds more than five times as fast as sound.

Part of the difficulty is that such catastrophes are often “compound events” in which multiple factors combine to wreak havoc.
Continue reading Compound interestSwinburne University researchers have developed a way to bring 3D printing with carbon fibre composites to an industrial scale.
Strong, lightweight carbon fibre composites can be used to make everything from aeroplanes and high-end race cars to sports equipment, and they are in high demand.
Continue reading 3D printing carbon fibre at industrial scaleBushfires are becoming more intense and increasing their range—so European and Australian researchers have initiated a five-year joint project to combat the threat.
“New regions are becoming affected by recurrent fires,” says Associate Professor Marc Demange from the Royal Melbourne Institute of Technology (RMIT).
Continue reading Sharing knowledge, fighting firesTo rein in global warming, scientists believe it will not be enough to reduce our greenhouse gas emissions: we will also need to remove CO2 from the atmosphere.
Soils are an important reservoir for carbon, as they contain nearly double that found in the atmosphere and vegetation combined. Agricultural practices have degraded soil carbon stocks, so there is a large potential for atmospheric carbon to be sequestered in soils.

Rudy Kloser, an expert on echo sounding and deep-sea ecosystems at CSIRO in Hobart, says these creatures are vital but poorly understood. Continue reading Spying on the denizens of the Southern Ocean
From his lab at the South Australian Health and Medical Research Institute (SAHMRI), Irish-born researcher David Lynn is combining computational and big data analysis with experimental approaches to unpicking biological networks at the molecular level. Continue reading Big data for life
Though Cyprus is blessed with plentiful sunshine, rainfall is low and the country depends on energy-intensive desalination plants for its drinking water. Continue reading Australian mirrors helping to power Cyprus
