For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A ...

Discovering a new class of matter in the lab of Chiara Daraio at Caltech, researchers have identified a type of material that uniquely responds to stress, behaving like a fluid under some conditions ...

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 ...
