Scientists have devised a way to use current gravitational-wave detectors to observe permanent deformations of spacetime caused by certain supernovae.

An analysis of gravitational data from the LIGO detector sets new limits on a wave-like form of dark matter called scalar-field dark matter.

Researchers use ultrashort laser pulses to trigger a spin-aligned electron flow on the few-femtosecond timescale—opening up a possible path toward faster spintronic devices.
