The cold, oxygen-free sediment at the bottom of the sea hosts a wealth of microbes. Many bacteria living there survive by metabolizing methane as a carbon source, and researchers had assumed that archaea did the same. But researchers led by geomicro­biologist Bo Barker Jørgensen at Aarhus University, in Denmark, have found evidence for something different: Archaea appear to dine on proteins lurking in the marine sediment (Nature, DOI: . . .
