So-called “higher symmetries” are illuminating everything from particle decays to the behavior of complex quantum systems.

If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection.

In the math of particle physics, every calculation should result in infinity. The set of techniques known as “resurgence” points toward an escape.

There once was a cosmic seed that sprouted the Milky Way galaxy. Astronomers have discovered its last surviving remnants.

Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened.

Cosmologists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter.

A paper in Nature reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community.

New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.

There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going on.
