HOPES that we will find life on Mars have been dented by the claim that something is quickly destroying methane. This suggests conditions on the planet are much harsher than we thought.

This was a surprise, because the gas should have spread evenly around the planet, so Franck Lefevre and François Forget of the Pierre and Marie Curie University in Paris, France, created a climate model to explain how such concentrations might form. The pair found that to recreate the observations,
