For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A wave of recent experiments is now tearing at those boundaries, revealing ...

Solid, liquid, gas … and something else? While most of us learn about just three states of matter in elementary school, physicists have discovered several exotic varieties that can exist under extreme ...

Scientists have discovered a new state of matter that isn't a solid, liquid, or gas. Researchers call this new type of material a 'corralled supercooled liquid'. Atoms in a liquid are normally like ...

You learn about three or four phases of matter in school—solids, which have a shape and volume, liquids, which have a volume only, and gases and plasmas, which have neither a definite shape nor volume ...
