How light can vaporize water without the need for heat

It's the most fundamental of processes—the evaporation of water from the surfaces of oceans and lakes, the burning off of fog in the morning sun, and the drying of briny ponds that leaves solid salt behind. Evaporation ...

How molecular 'handedness' emerged in early biology

Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions akin to the left and right versions of human hands. One of the great mysteries about the origins ...

It's a fine line between a black hole energy factory and a black hole bomb

Black holes are powerful gravitational engines. So you might imagine that there must be a way to extract energy from them given the chance, and you'd be right. Certainly, we could tap into all the heat and kinetic energy ...
