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.

One way to produce clean water is to heat dirty water until it turns into steam. As the steam rises, it leaves behind the heavier contaminants and can be collected and cooled, providing clean water. There are many ways to ...
(Phys.org) —A team of researchers at Rice University has developed a solar powered autoclave based on solar energy and metal and carbon nanoparticles. In their paper published in the journal Proceedings of the National ...
The media often imply that the goal of the hunt for extrasolar planets is to find a rocky planet about the size of Earth orbiting a star like the sun at a distance that would allow liquid water to persist on its surface. ...

Carmelo Ferlito, a volcanologist at Università di Catania, in Sicily, has suggested in a paper published in the journal Earth-Science Reviews that Mt. Etna behaves more like a giant hot spring than a volcano. He is not, ...
Salmon largely disappeared from the Netherlands due to the construction of water mills, ecologists from Radboud University conclude (Scientific Reports, 20 July). The construction of water mills caused the destruction of ...
