As you use computers, as you’re surfing the web, especially in large data centres, it generates a lot of heat. And right now, that heat is wasted. It actually just gets pulled away and goes out through the chimneys, etc. Well, our scientists are putting small channels actually into the chips that do the computing, taking that heat back and using heat pump technology to then heat a building or even cool a building. So the energy will be reclaimed. So computing will become a lot more energy efficient.

For decades scientists have followed penguins by putting bands around their flippers. This allows individual birds to be identified at a distance. But there have been concerns that flipper bands might harm the birds by slowing them down as they swim. The latest study, reported in the journal Nature, confirms it. Scientists from Strasbourg University followed a colony of king penguins for ten years.
