Photons May Emit Faster-Than-Light Particles, Physicists Suggest

The particles that make up light, photons, may live for at least 1 quintillion (1 billion multiplied by 1 billion) years, new research suggests. Full story

Strange Particles Shape-Shift From One Flavor to Another

Exotic particles called neutrinos have been caught in the act of shape-shifting, switching from one flavor to another, in a discovery that could help solve the mystery of antimatter. Full story

Physicists unveil results helping explain universe

After a quarter-century of searching, scientists have nailed down how one particularly rare subatomic particle decays into something else — a discovery that adds certainty to our thinking about how the universe began and keeps running. Full story

Weird Neutrinos Elude Scientists Yet Again

Though they've been looking for over a year, scientists have found no trace of an elusive interaction among elementary particles called neutrinos. Full story

5 Mysterious Particles Lurking Underground

While the world's largest atom smasher was busy finding the Higgs boson particle — thought to explain why other particles have mass — physicists have been quietly building giant underground laboratories deep beneath the Earth. Full story
