    Nobel prize: Physics

    Three scientists have jointly won the 2001 Nobel Prize in Physics for creating the first samples, 6 years ago, of a long-sought and strange state of matter called a Bose-Einstein condensate.

    Magnets, not magic, make gas bulbs bad

    Once as baffling as black magic, the random failures of glass bulbs used in magnetic resonance imaging (MRI) now appear to stem from unexpected magnetization of the glass.

    Path to new elements now looks steeper

    Making novel, superheavy elements is harder than was previously expected, according to a new experiment, but the findings may also help physicists better choose which atoms to smash into which.

    Constant Changes

    Evidence from the early universe that one of the so-called constants of nature, known as alpha, was once slightly smaller than it is today hints that the laws of physics themselves may vary over time and space.
