A new phase of matter called a “time crystal” plays with our expectations of thermodynamics. The physicist Vedika Khemani talks with Steven Strogatz about its surprising quantum behavior.

A new analysis argues that ubiquitous eruptions in the sun’s corona explain the vast flow of charged particles seen streaming out through the solar system.

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.
