What's up in
A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.
While studying materials made from DNA-coated nanoparticles, researchers found a new form of this matter: lattices in which smaller particles roam like electrons in metallic bonds.
At stake are fundamental ideas about how black holes form — and a six-way bet.
The theoretical particle physicist Ann Nelson, who died on August 4 at age 61, was a font of brilliant ideas and a champion of ending discrimination in the field.
New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.
Carlo Rubbia, leader of the bold collider experiment that in 1983 discovered the W and Z bosons, thinks particle physicists should now smash muons together in an innovative “Higgs factory.”
