Vacuum in optical cavity can change material's magnetic state without laser excitation

Protostars Can Siphon Material from Far Away

Groundbreaking study shows defects spreading through diamond faster than the speed of sound. Defects can make a material stronger or fail catastrophically. Knowing how fast they travel can help researchers understand things like earthquake ruptures, structural failures and precision manufacturing.

A Star Threw Off a Sun’s Worth of Material. And Then it Exploded!
