‘Milestone’ Evidence for Anyons, a Third Kingdom of Particles
Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.
Top Dark Matter Candidate Loses Ground to Tiniest Competitor
Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.
Physicists Finally Nail the Proton’s Size, and Hope Dies
A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.
Strange Metal-like Bonds Discovered in Customized Crystals
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.
A Call for Courage as Physicists Confront Collider Dilemma
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.”
Physicists Peer Inside a Fireball of Quantum Matter
Experimenters in Germany have glimpsed the kind of strange, non-atomic matter thought to fill the cores of merging neutron stars.
