    Light shines in quantum-computing arena

    A new computing scheme using available technology and only classical physics appears to handle many tasks that researchers thought would be unsuited to any computers except the still-hypothetical ones that would exploit quantum physics.

    Device shifts molecules into slow motion

    Unlike other particle accelerators, which manipulate the speed and energy of charged particles, a new device accelerates neutral molecules such as ammonia.

  3. Physics

    Lead blocks may catch nuclear killer

    New measurements of neutron bursts from blocks of lead may help researchers solve a decades-old cosmic whodunit.

  4. Physics

    Maybe this watched pot already boiled

    Researchers smashing nuclei in hopes of producing a primordial state of matter called the quark-gluon plasma may have already made the stuff without realizing it.

  5. Physics

    New probe reveals unfamiliar inner proton

    Researchers taking one of the closest looks yet into the intact proton have found an unexpectedly complex interior electromagnetic environment.

  6. Materials Science

    Inorganic tubes get smaller than ever

    Researchers have created the smallest stable, freestanding inorganic nanotubes yet.

  7. Materials Science

    Novel nanotubes are now made-to-order

    Researchers have made nanotubes with specific sizes and traits by designing molecules that self-assemble.

  8. Physics

    Surface reaction recorded in real time

    Ultrafast laser pulses may have for the first time revealed the incredibly rapid, step-by-step progress of a complete chemical reaction on a surface, at the actual speed at which it took place.

  9. Physics

    Cold sliver may sense electron quiver

    By detecting vibrations of less than an atom's width of a tiny cantilever, physicists have made the most sensitive measurement of force ever by mechanical means.

  10. Physics

    Moon may radio cosmic rays’ biggest hits

    Efforts to use the moon to detect the highest-energy cosmic rays get a boost from an experiment showing that gamma rays zipping through a giant sandbox cause the kind of microwave bursts moon-watchers are hoping to see.

  11. Physics

    Frigid ‘dynamite’ assembles into superatom

    Although it's now the fifth element to be made into the strange state of ultracold matter known as Bose-Einstein condensate, helium may prove to be the most revealing so far because of unusually high energies within the newly condensed atoms.

  12. Physics

    Some swell materials give up their secret

    The discovery of a previously overlooked crystal structure in the best so-called piezoelectric materials may explain their remarkable amount of swelling when zapped by an electric field.
