Non-trivial spacetime shape provides topological protection against quantum fluctuations that should make the constant enormous.

Stable plasma waves enable free-electron laser amplification at extreme ultraviolet wavelengths in just a few millimeters of acceleration.

LUX-ZEPLIN recorded a single particle interaction that could be a WIMP 200 times heavier than a proton. At 2.6 sigma, it has a 0.5% chance of being background.

Neutron stars might be surrounded by clouds of tiny particles called axions, and this might help explain dark matter.
