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 ...

Experiments have yielded a fascinating new type of matter, neither granular nor crystalline, that responds to some stresses as a fluid would and to others like a solid. The new material, known as PAM ...

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 ...
