    Atomic Crowds Tied by Quantum Thread

    Quantum states of record numbers of atoms—entire atom clouds—get blended together by physicists wielding a new, relatively simple technique in quantum telecommunications and computing.

  2. Materials Science

    Ceramics stretch for future applications

    Researchers have created a ceramic that stretches to 10 times its original length in record time.

  3. Physics

    Model may expose how friction lets loose

    Rather than just grinding past each other, sliding surfaces may tremble with minuscule ripples that overcome friction as they move along.

  4. Materials Science

    Materials use nitric oxide to kill bacteria

    A novel coating may offer a new way to fend off microbial buildup on catheters, artificial hips, and replacement cardiac valves.

  5. Materials Science

    Speed demon gets hooked on silicon

    A method for coating silicon with high-performance semiconductors such as gallium arsenide may make faster, low-power microcircuits both cheaper and more widespread.

  7. Physics

    Window Opens into Strange Nuclei

    By creating peculiar atomic nuclei that contain not just protons and neutrons but also pairs of rare nuclear particles with so-called strange quarks inside, researchers are shedding new light on the fundamental structure of matter and how it behaves under extreme conditions, as in neutron stars.

  8. Physics

    Accelerators load some new ammo: Crystals

    To make denser accelerator beams that may open new doors in physics, researchers have chilled ions in a miniature test accelerator until the ions coalesced into crystals.

  9. Materials Science

    Chemical sensors gain true portability

    Researchers have designed simple new films for indicating the presence of worrisome airborne chemicals.

  10. Physics

    Electrons rock and roll in nanotubes

    New probes of tiny carbon nanotubes reveal that the wavelike, quantum nature of electrons plays a role in tube properties and may even make possible novel electronic components that harness quantum effects.

  11. Physics

    Insects in the wind lead to less power

    A previously puzzling pattern of power loss in wind turbines results from coatings of insects that were smashed by the blades during low winds.

  12. Physics

    Turning magnetic resonance inside out

    A new method of manipulating magnetic signals makes it possible to gather useful information about a chemical sample—or perhaps one day a person—without often-claustrophobic confinement inside a magnetic coil.
