Preventing concrete bridges from falling apart

Extremes of temperature, rain, exposure to corrosive substances—all of these environmental factors contribute to the degradation of concrete. Specifically, a gas present in our environment, called hydrogen sulphide, turns ...

Paving the way for more efficient hydrogen cars

Hydrogen-powered vehicles emit only water vapor from their tailpipes, offering a cleaner alternative to fossil-fuel-based transportation. But for hydrogen cars to become mainstream, scientists need to develop more efficient ...

Geoscientists discover an overlooked source for Earth's water

Where did Earth's global ocean come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents' Professor in ASU's School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has ...

Astronomers witness slow death of nearby galaxy

Astronomers from The Australian National University (ANU) and CSIRO have witnessed, in the finest detail ever, the slow death of a neighbouring dwarf galaxy, which is gradually losing its power to form stars.

Image: Cloudlets swarm around our local supermassive black hole

This image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows the area surrounding Sagittarius A*, the supermassive black hole that lurks at the centre of the Milky Way—highlighted here with a small circle. ...

Artificial enzymes convert solar energy into hydrogen gas

In a new scientific article, researchers at Uppsala University describe how, using a completely new method, they have synthesised an artificial enzyme that functions in the metabolism of living cells. These enzymes can utilize ...
