Origami inspires highly efficient solar steam generator

Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. ...

New technology improves hydrogen manufacturing

Industrial hydrogen is closer to being produced more efficiently, thanks to findings outlined in a new paper published by Idaho National Laboratory researchers. In the paper, Dr. Dong Ding and his colleagues detailed advances ...

Why steam burns are particularly vicious

Even if the wound looks superficially harmless, steam burns must be cooled persistently. Empa researchers have now been able to show for the first time how hot steam achieves its vicious effect: It penetrates the upper skin ...

The thermodynamics of computing

Information processing requires a lot of energy. Energy-saving computer systems could make computing more efficient, but the efficiency of these systems can't be increased indefinitely, as ETH physicists show.

Scientists create 'Swiss army knife' for electron beams

DESY scientists have created a miniature particle accelerator for electrons that can perform four different functions at the push of a button. The experimental device is driven by a terahertz radiation source and can accelerate, ...

Bali volcano belches steam, sulphur as more evacuees flee

A rumbling volcano on the holiday island of Bali is spewing steam and sulphurous fumes with more intensity, heightening fears of an eruption as officials said the number of evacuees had topped 144,000.

Video: When water levitates

Have you ever seen a drop of water navigate a maze? It's possible thanks to the same phenomenon that lets you know if a griddle is hot enough for pancake batter. Water droplets that dance and skitter across a hot surface ...
