Scientists caught a black hole ringing like a bell
Two black holes merged, creating a new, bigger one. This event triggered the clearest ripples in spacetime ever observed.

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.
