How hidden soil fungi ‘steal’ bacterial DNA to control the rain

Tiny organisms on the ground – bacteria and fungi – have a “superpower” that allows them to reach up into the atmosphere and pull down the rain, according to a recent study.

To understand how a microbe can control a storm, we first have to look at how clouds become rain. High up in the atmosphere, water doesn’t always freeze at 0°C. Temperatures are normally much lower at cloud level but pure water can…
