For the first time, Northwestern University scientists have watched water molecules in real-time as they prepared to give up electrons to form oxygen. In the crucial moment before producing oxygen, ...

Water behaves in remarkable ways when heated and pressurized beyond its critical point. Under these extreme conditions, known as supercritical water, it no longer acts like an ordinary liquid. Instead ...

Water has a split personality. When it’s flowing freely in a glass or a river, it’s the easygoing liquid we all know. But trap it inside the tiny pockets of a protein or a synthetic molecule, and it ...

The movement of protons through electrically charged water is one of the most fundamental processes in chemistry. It is evident in everything from eyesight to energy storage to rocket fuel — and ...

Water trapped inside tiny molecular cavities behaves in a surprisingly energetic way, pushing outward like people crammed in an elevator. When a new molecule enters these narrow spaces, the confined ...

They’re called comb jellies though they’re not jellyfish. And they are beautiful when exposed to the light. But where some of them live, 8,000 meters beneath the sea, there is no light and they have ...

Water, though familiar, still hides astonishing secrets. When squeezed into nanosized channels, it can enter a bizarre “premelting state” that is both solid and liquid at once. Using advanced NMR ...

NASA scientists have discovered water molecules in the polar regions of the moon. Instruments aboard three separate spacecraft revealed water molecules in amounts that are greater than predicted, but ...
