A New Twist Reveals Superconductivity’s Secrets

March 16, 2021

An unexpected superconductor was beginning to look like a fluke, but a new theory and a second discovery have revealed that emergent quasiparticles may be behind the effect.

Imaginary Numbers May Be Essential for Describing Reality

March 3, 2021

A new thought experiment indicates that quantum mechanics doesn’t work without strange numbers that turn negative when squared.

Physicists Study How Universes Might Bubble Up and Collide

January 25, 2021

Since they can’t prod actual universes as they inflate and bump into each other in the hypothetical multiverse, physicists are studying digital and physical analogs of the process.

Galaxy-Size Bubbles Discovered Towering Over the Milky Way

January 6, 2021

For decades, astronomers debated whether a particular smudge was close-by and small, or distant and huge. A new X-ray map supports the massive option.

The Search for Dark Matter Is Dramatically Expanding

November 23, 2020

Physicists plan to leave no stone unturned, checking whether dark matter tickles different types of detectors, nudges starlight, warms planetary cores or even lodges in rocks.

Room-Temperature Superconductivity Achieved for the First Time

October 14, 2020

Physicists have reached a long-sought goal. The catch is that their room-temperature superconductor requires crushing pressures to keep from falling apart.

A New Cosmic Tension: The Universe Might Be Too Thin

September 8, 2020

Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?
