A revolution is underway in the development of autonomous wireless sensors, low-power consumer electronics, smart homes, domotics and the Internet of Things. All the related technologies require efficient and easy-to-integrate energy harvesting devices for their power. Billions of wireless sensors are expected to be installed in interior environments in coming decades.

Indoor photovoltaic (PV) power sources on ultra-thin curvable substrates have the potential to facilitate these technological in...

In a study recently published in the Monthly Notices of the Royal Astronomical Society, Dr. Jade Powell and Dr. Bernhard Mueller from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) simulated three core-collapse supernovae using supercomputers from across Australia, including the OzSTAR supercomputer at Swinburne University of Technology. The simulation models—which are 39 times, 20 times and 18 times more massive than our sun— revealed new insights into exploding massive stars and the next generation of gravitational-wave detectors.

Core-collapse supernovae are the explosive deaths of massive stars at the end of their lifetime...

The brain has a powerful ability to remember and connect events separated in time. And now, in a new study in mice, scientists have shed light on how the brain can form such enduring links.

A woman walking down the street hears a bang. Several moments later she discovers her boyfriend, who had been walking ahead of her, has been shot. A month later, the woman checks into the emergency room. The noises made by garbage trucks, she says, are causing panic attacks...

Computers, mobile phones and all other electronic devices contain thousands of transistors, linked together by thin films of metal. Scientists at Linköping University, Sweden, have developed a method that can use the electrons in a plasma to produce these films.

The processors used in today’s computers and phones consist of billions of tiny transistors connected by thin metallic films. Scientists at Linköping University, LiU, have now shown that it is possible to create thin films of metals by allowing the free electrons in a plasma take an active role...
