A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps ...

New physics target: Researchers set first constraints on possible dark matter–linked forces between electrons and nuclei using molecular measurements. Molecules as detectors: Heavy polar molecules ...

The muon mismatch was caused by calculation limits, not a new force. Improved methods bring theory and experiment into close ...
