    Jiggling the Cosmic Ooze

    Spurred by the first tentative sightings after a decades-old search, physicists seeking the universe's mass-giving particle — the Higgs boson — have fired up the world's highest-energy particle collider to join the pursuit.

    Physicists get B in antimatter studies

    New observations that subatomic particles called B mesons decay differently from their antimatter versions may help explain why the universe is made almost entirely of matter, not antimatter.

    Run-of-the-mill compound becomes superstar

    The discovery that simple, common magnesium diboride can conduct electric current without resistance and does so at a surprisingly high temperature has sent physicists racing to understand its properties and to try to improve upon them.

    Seeming sedate, some solid surfaces seethe

    Although they're as orderly as bathroom-floor tiles, surface atoms of copper--and perhaps other solids--actually roam randomly and widely within their grid.
