A new paper from cfaed’s Chair for Molecular Functional Materials describes a new approach to revolutionize the production of molecular hydrogen. In many of the approaches for hydrogen production, the electrocatalytic hydrogen evolution reaction (HER) from water splitting is the most economical and effective route for the future hydrogen economy...

Monash researchers have identified a new concept – ‘orphan memory’ – which changes the current thinking around gravitational waves. Einstein’s theory of general relativity predicts that cataclysmic cosmic explosions stretch the fabric of spacetime. The stretching of spacetime is called ‘gravitational waves.’ After such an event, spacetime does not return to its original state. It stays stretched out. This effect is called ‘memory.’ The term ‘orphan’ alludes to the fact that the parent wave is not directly detectable.

“These waves could open the way for studying physics currently...

A false-color image map of the gas density in the Musca star-forming filament (the highest densities are shown in red). New theoretical work on the structure of these long filaments proposes several kinds of star-forming zones along the length and successfully reproduces many of the features seen in filaments like this one in Musca. Kainulainen, 2016

Interstellar molecular clouds are often seen to be elongated and “filamentary” in shape, and come in a wide range of sizes. In molecular clouds, where stars form, the filamentary structure is thought to play an important role in star formation as the matter collapses to form protostars...

Lipogems® is a non-expanded and microfragmented adipose tissue graft that is injected into damaged areas of the body in order to provide a cushion and structural support while promoting a healing environment. Lipogems® preserve the natural healing properties of adipose tissue by maintaining the fats Vascular Stromal Niches which contain mesenchymal cells and pericytes.

Body fat now can help treat bone joint conditions, including injuries and osteoarthritis – the type of arthritis caused by wear and tear in tissue between joints, which affects 27 million people. A new device gently suctions, processes and uses a patient’s own fat tissue to provide a potential source of stem cells and growth factors to promote healing...
