‘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

With performance three times better than copper’s, this new material could substantially improve heat management of electronics, data centers and energy systems

A new calculation helps narrow down the mass of the W boson, one of the heaviest fundamental particles in the universe

A single subatomic particle from deep space had the same energy as a baseball pitch, and scientists still don’t know how it got here

Scientists at CERN built a container weighing about a ton to transport just 92 subatomic antimatter particles without annihilating them

The Large Hadron Collider just produced a never-before-seen particle made of charm and down quarks
