  1. Particle Physics

    Exotic particle packs a foursome of quarks

    Tetraquarks could help physicists understand the universe’s first generations of matter.

  2. Cosmology

    Galaxy’s gamma-ray glow may expose dark matter

    An excess of gamma rays at the center of the Milky Way could be a signature of dark matter.

    Catching Particle Fever

    Interspersed with the plot of Particle Fever are artful explanatory animations and commentary by six articulate physicists. Through these characters, we learn that the Higgs is a stepping stone toward a deeper understanding of the universe.

    More precision added to mass estimate of electron

    The electron has been weighed with unprecedented precision. Its new and improved mass is 17 times as precise as the previous best estimate.

  5. Particle Physics

    Single-pole magnet emerges in frozen concoction

    An experiment has simulated the long-sought magnetic particle.

  6. Particle Physics

    Electrons’ roundness frustrates researchers

    Experiment finds no signs of asymmetry, which would point to undiscovered particles.

  7. Particle Physics

    Higgs boson tale wins book prize

    The Particle at the End of the Universe by Sean Carroll.

  8. Physics

    Cruise through a collider

    Now anyone can tour the Large Hadron Collider and other CERN experiments in 360-degree photo panoramas online.

  9. Astronomy

    High-energy neutrinos ensnared from beyond the solar system

    Speedy particles detected in Antarctica may point to gargantuan black holes or cataclysmic explosions.

  10. Particle Physics

    Higgs mass isn’t natural, but maybe it shouldn’t be

    Famous particle’s perplexing properties suggest physicists should change their expectations.

  11. Physics

    It’s too soon to declare supersymmetry a tragedy

    Supersymmetry is the odds-on favorite to solve many of the mysteries about the physical world that have stumped theorists for decades. Supposedly the LHC should produce actual evidence for SUSY, but it hasn’t. And so some physicists have begun to declare SUSY dead, or at least on life-support.

    Nobel’s sharp cuts

    Gerald Guralnik was home when he learned online that physicists François Englert and Peter Higgs had won the Nobel Prize in physics for formulating the same theory he had proposed nearly 50 years ago.
