Physicists Just Learned Something Major About the Proton
Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behaviour are nearly imperceptible. But now, by exploiting decades-old data and a 50-year-old prediction about gravity’s import on subatomic particles, a team of physicists has teased out a measurement for a second mechanical property in…

Faster-Than-Light ‘Quasiparticles’ Touted as Futuristic Light Source
Nothing can travel faster than light, or 299,792,458 meters per second. But a certain group of particles acts as if it can, a team of physicists recently concluded, potentially paving the way for a powerful light source that could reveal new kinds of science. When electrons are excited and pushed around, they produce light of…
