Tiny gas-filled bubbles in the porous rock found around hot springs are thought to have played an important role in the origin of life. Temperature differences at the interface between liquid phases could therefore have initiated ...

Methane is not only a powerful greenhouse gas, but also a source of energy. Microorganisms therefore use it for their metabolism. They do so much more frequently and in more ways than was previously assumed, as revealed by ...
