  1. Physics

    Candy Science: M&Ms pack more tightly than spheres

    Squashed or stretched versions of spheres snuggle together more tightly than randomly packed spheres do.

  2. Physics

    Two New Elements Made: Atom smashups yield 113 and 115

    Two new elements—115 and 113—have joined the periodic table.

  3. Materials Science

    Pumping Carbon: Researchers watch nanofibers grow

    The first atomic-scale movies of carbon nanofiber growth show particles of a metal catalyst pulsating wildly while carbon and metal atoms scuttle across the particle’s surface.

  4. Physics

    Skipping stones 101

    Using their own stone-skipping machine, physicists have found what may be the best angle for a rock to hit the water in order to achieve the most skips.

  5. Physics

    New signs of shadow particles

    The influence of as-yet-undiscovered heavy particles outside of today's prevailing theory of particle physics may have accelerated the rate at which subatomic muons wobbled in a recent experiment.

  6. Physics

    Wet ‘n’ Wild

    Scientists have tracked the weirdness of water to microscopic arrangements of molecules and perhaps to the existence of a second, low-temperature form of the familiar substance.

  7. Physics

    A Solid Like No Other: Frigid, solid helium streams like a liquid

    Frozen helium prepared in a laboratory has apparently transformed into a superfluid solid, or supersolid—a never-before-seen phase of matter that theorists predicted more than 30 years ago.

  8. Tech

    Tapping sun’s light and heat to make hydrogen

    Researchers have demonstrated a highly efficient means of splitting water molecules to generate hydrogen fuel.

  9. Physics

    Light pulse hovers in atom capsule

    A new way to freeze light pulses in midflight preserves the pulses' optical energy and may eventually lead to using stationary light in optical circuits and quantum computers.

  10. Tech

    Electronic skin senses touch

    A pressure-detecting membrane laminated onto a sheet of flexible plastic electronics may lead to artificial skin for robots.

  11. Tech

    Flashy Transistors: Electronic workhorses also shed light

    Researchers have discovered that the transistor can emit light, a yet-untapped talent.

  12. Physics

    Topsy Turvy: In neutrons and protons, quarks take wrong turns

    Revved-up particles, namely quarks, spinning inside neutrons in the opposite direction to that of the neutrons themselves, challenge the prevailing model of how quarks behave.
