Neutrinos are known for funny business. Now scientists have set a new limit on a quantum trait responsible for the subatomic particles’ quirkiness: uncertainty. The lightweight particles morph from ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

Today the University of Edinburgh announced the death of the Nobel Prize-winning physicist Peter Higgs. As NPR's Geoff Brumfiel reports, Higgs was a reclusive, brilliant researcher whose insights ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...

The discovery of a new subatomic particle that may be the elusive Higgs boson has electrified the entire field of physics. The particle has... New Subatomic Particle May Be Physics' Missing Link ...

The Nobel-Prize-winning physicist Peter Higgs has died at age 94. He was celebrated for his work on the mass of subatomic particles. Today the University of Edinburgh announced the death of the Nobel ...
