  1. Physics

    Light rambles through room-temperature ruby

    Researchers have dramatically slowed light within a solid at room temperature.

  2. Physics

    Attractive atoms pick up repulsive habits

    Rubidium atoms intrinsically attract each other, but new experiments near absolute zero have induced the atoms to repel each another instead.

  3. Physics

    Rare Events: Exotic processes probe the heart of matter

    Physicists have for the first time unambiguously detected and measured the rates of certain reactions among protons, neutrons, and simple atomic nuclei.

  4. Physics

    Why is antimatter absent? Hunt heats up

    Two new particle accelerators built to help discover why there's matter instead of antimatter in the universe are closing in on an answer at record speed.

  5. Materials Science

    A Hard Little Lesson: Squeezed nanospheres grow superstrong

    A substance not known for its hardness—silicon—becomes one of the hardest of materials when formed into ultrasmall spheres.

  6. Computing

    Pictures Only a Computer Could Love

    New, unconventional lenses shape scenes into pictures for computers, not people, so that computer-equipped microscopes, cameras, and other optical devices can see more with less.

  7. Physics

    Matter’s Missing Piece Shows Up

    The first direct evidence of the tau neutrino, the last of the 12 subatomic particles considered the fundamental building blocks of matter, has finally been found.

  8. Physics

    Muon Manna? Particle shower may spotlight loose nukes

    Radiation from space may help border guards spot loose nukes stowed in shipping containers.

  9. Physics

    Squirming through space-time

    In the exotic realm of curved space, the topography of space itself might provide a propulsion assist—albeit a tiny one.

  10. Physics

    In orbit, water makes the stretch

    An astronaut-at-play stumbled upon an unexpected behavior of water in near-zero gravity: The formation of durable films—some as wide as saucers—that would instantly break here on Earth.

  11. Physics

    Bunches of atoms madly morph

    While investigating the instability of tiny clusters of atoms, scientists observe ultrasmall salt grains switching shapes at a stupendous rate.

  12. Physics

    New approach smooths wrinkle analysis

    A simple new theory of wrinkle formation predicts basic traits of wrinkled surfaces, such as how close together the folds will be, without miring scientists in impossible-to-solve equations.
