Researchers have nailed down an elusive quantity called baryon number, which may be responsible for the cosmic mismatch between matter and antimatter

For almost 60 years, a global ban on nuclear weapons in space has held up. But the growing number of satellites and increasing geopolitical tension has scientists worried the moratorium could fail

After decades of debate, the scientific case is clear for Europe’s Future Circular Collider, a colossal successor to the Large Hadron Collider. But transforming this megaproject from vision to reality is far from guaranteed

Noether's work helped prove the conservation of energy in physics, a key foundation for Einstein's theory of relativity

The energy entrepreneur talks about the state of science innovation in the U.S.

‘Penguin’ decays from CERN’s latest Large Hadron Collider experiment hint at weird new physics

There are parts of the universe, and of the electromagnetic spectrum, that we’re not covering with our telescopes—but not as many as you might think!

Long-held assumptions tell us that atoms with the same number of protons, neutrons and electrons are indistinguishable, but one physicist wants to put this idea to the test

The Deep Underground Neutrino Experiment will study nature’s most mysterious particle a mile beneath South Dakota’s Black Hills and will potentially reveal the origins of matter

A recent experiment revealed that individual dark points on a light wave can move faster than the wave itself

After winning a Breakthrough Prize, the world’s most lucrative science award, theoretical physicist David Gross is using the moment to warn of nuclear war’s existential threat—and how we can escape it

This year’s winners include hundreds of physicists across more than 30 institutions
