A re-examination of a particle discovered in 2015 has scientists debating its true identity.
Quantum entanglement, doubted by Einstein, has passed increasingly stringent tests.
The bottom quark may lead physicists on a path to new discoveries.
When they look for violations of Einstein’s general relativity, physicists deliberately plan experiments to find nothing at all.

Standard Model predictions align with the LHCb experiment’s observation of an uncommon decay.
Scientists furthered studies of the Higgs boson, neutrinos, dark matter, dark energy and cosmic inflation and continued the search for undiscovered particles, forces and principles.
A theoretical species of particle might answer nearly every question about our cosmos—if scientists can find it.
Physicists exchanged cognac in Copenhagen at the conclusion of a bet about supersymmetry and the LHC.
