Researchers crashed two beams of protons together at the highest energy level yet achieved.
A Japanese cargo ship that arrived on Monday at the space station delivered an astrophysics telescope that will join the flagship Alpha Magnetic Spectrometer in hunting for cosmic rays.
In a new blow for the futuristic 'supersymmetry' theory of the universe's basic anatomy, experts reported fresh evidence Monday of subatomic activity consistent with the mainstream Standard Model of particle physics.
Physicists have discovered the elusive pentaquark -- a collection of five quarks bound together to form an exotic state of matter.
A dwarf galaxy orbiting the Milky Way is humming with gamma rays, leading astronomers to hypothesize that it could be filled with annihilating dark matter particles.
The Large Hadron Collider (LHC) is the largest and most complex machine ever constructed, so it can be hard to fully appreciate its scale.
Version 2.0 of CERN's large hadron collider is set to get back in the discovery business next month, boasting twice the power, tougher wiring, better cooling systems, and upgraded cameras.
We may have found evidence that elusive, mysterious dark matter -- something for which there is no direct proof -- is actually sterile neutrinos. And that's going to take some explaining, by way of a speed-tutorial on quantum mechanics from Julian.
