Oil-eating bacteria could help to tackle spills

A team of scientists from Heriot-Watt University has created an underwater observatory in the Faroe-Shetland Channel—and found its waters are teeming with oil-eating bacteria that could help deal with future oil spills.

Mysterious magnetic fossils offer past climate clues

There are fossils, found in ancient marine sediments and made up of no more than a few magnetic nanoparticles, that can tell us a whole lot about the climate of the past, especially episodes of abrupt global warming. Now, ...
