U.S. closes atom smasher, passes baton to Europe

The powering down of Fermilab's Tevatron particle accelerator on Friday marked the end of a quarter-century of U.S. dominance in high-energy particle physics. Full story

Higgs boson rumor as elusive as particle itself

A rumor is floating around the physics community that the world's largest atom smasher may have detected a long-sought subatomic particle called the Higgs boson, also known as the "God particle." Full story

Proton-smasher breaks record for intensity

The world's largest particle accelerator, the Large Hadron Collider, has set a new world record by smashing together two beams with more particles than ever before. Full story

New subatomic particle: real or anomaly?

The announcement this week that scientists may or may not have discovered a new subatomic particle has riled up the physics world. So how do we know for sure whether the particle is real or not? Full story

Heaviest antimatter yet produced debuts

It seems antimatter might have a bit of a weight problem these days, if a new paper on the arXiv is to be believed — specifically, antimatter helium-4, an extremely rare (and heavy!) particle that just made its debut at Brookhaven's Relativistic Heavy Ion Collider (RHIC). Full story

Exotic antimatter particle exhibits new conduct

A rare particle containing equal parts weird antimatter and normal matter has popped up in experiments at the world's largest particle accelerator. Full story

  Physicist says ‘new particle observed’

CMS spokesperson Joe Incandela reports in a CERN video that a new particle has been observed at Europe's Large Hadron Collider.

  Scientists uncover ‘God particle’

Physicists at Cern, a nuclear research facility in Switzerland, are expected to announce that they have finally found the Higgs Boson, a sub-atomic particle. Derrick Pitts, chief astronomer at the Franklin Institute, discusses.
