Thunderstorms churn up a ‘boiling pot’ of high-energy gamma rays
A thunderstorm seen in gamma ray vision plays out as a complex, frenzied lightshow above the clouds.

Heat makes water evaporate. Now it appears light can, too
In the lab, shining light on water made it evaporate faster. This never-before-seen effect, if real, might be happening naturally all around us.
