Australia on Wednesday approved plans for a massive solar and battery farm that would export energy to Singapore, a project it calls the “largest solar precinct in the world”.

Authorities announced environmental approvals for SunCable’s US$24 billion project in Australia’s remote north that is slated to power 3million homes.

The project, which will include an array of panels, batteries and, eventually, a cable linking Australia with Singapore, is backed by tech billionaire and green activist Mike Cannon-Brookes.

“It will be the largest solar precinct in the world –- and heralds Austral...

High-resolution images show large spots on the surface of Polaris. Researchers using Georgia State University’s Center for High Angular Resolution Astronomy (CHARA) Array have identified new details about the size and appearance of the North Star, also known as Polaris. The new research is published in The Astrophysical Journal.

Earth’s North Pole points to a direction in space marked by the North Star. Polaris is both a navigation aid and a remarkable star in its own right. It is the brightest member of a triple-star system and is a pulsating variable star...

Heart failure is a leading cause of death worldwide and is especially deadly for people who don’t have access to medical facilities. A team of researchers aims to bring heart failure screening from the lab to the home with a point-of-care electrochemical biosensor prototype that measures levels of two biomarkers for heart failure in as little as 15 minutes from just a drop of saliva.

Trey Pittman, a graduate student at Colorado State University, will present his team’s research at the fall meeting of the American Chemical Society (ACS).

“Our device would be ideal for people who are at high risk for heart failure but have limited access to a ...

Researchers have identified the specific locations from which most of the approximately 200 Martian meteorites originate. They’ve traced the meteorites to five impact craters within two volcanic regions on the red planet called Tharsis and Elysium. Their study was published recently in the journal Science Advances.

Martian meteorites find their way to Earth when something hits the surface of Mars hard enough so that material is “blasted off the surface and accelerated fast enough to leave Mars’ gravity,” says Chris Herd, curator of the U of A’s Meteorite Collection and professor in the Faculty of Science...
