    Scientists belt out a novel nanostructure

    Researchers have used metal oxides to make microscopic ribbonlike structures that could prove useful for developing future nanoscale devices.

    When warming up causes cooling down

    Under the right circumstances, heating a tiny cluster of sodium atoms makes its temperature fall.

  3. Physics

    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.

  5. Physics

    Lasers nudge into nuclear medicine

    Using a tabletop laser, researchers produced a medically useful isotope usually made in warehouse-size particle accelerators called cyclotrons.

  6. Physics

    Muffled shots tell a lot about snow

    A snowfield muffles gunshots in a way that can now be used to reveal important traits of the snow.

  7. Physics

    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.

    From Metal Bars to Candy Bars

    Materials scientists have turned the tools of their trade on some of the most familiar substances in the world: food.

  10. Physics

    Muon orbits may defy main physics theory

    A tiny discrepancy from theory in a newly remeasured magnetic trait of a subatomic particle, the muon, may represent a first crack in the 30-year-old prevailing standard model of particle physics.

  11. Materials Science

    Scientists develop self-healing composites

    Researchers have developed a composite material that has the ability to repair small cracks within itself, a characteristic that could be used to extend the reliability and service life of electronic and aerospace components.

  12. Materials Science

    Droplets string themselves together

    Under the right conditions, mixing two incompatible polymers can produce drops that organize themselves into strings.
