    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.

  2. Materials Science

    Chemical sensors gain true portability

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

  3. 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.

  4. 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.

  5. 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.

  6. Physics

    Quantum queerness gets quick, compact

    New ways to trap and cool atoms may hasten practical uses of strange ultracold atom clouds known as Bose-Einstein condensates.

  7. Materials Science

    Environment’s stuck with nonstick coatings

    Some nonstick coatings such as Teflon break down at high temperatures into undesirable compounds that persist in the environment.

  8. Materials Science

    Titanium dioxide hogs the spotlight

    Researchers have created new coatings that break down toxins and keep mirrors from fogging when the materials are exposed to visible light.

  9. Physics

    Antimatter mystery transcends new data

    The discovery of a disparity in decays of subatomic particles known as B mesons and anti-B mesons sheds light on how matter and antimatter differ but deepens the mystery of why matter predominates in the universe today.

  10. Physics

    Physics Bedrock Cracks, Sun Shines In

    The first data from a new Canadian detector of particles called neutrinos not only resolve a 30-year-old puzzle about how the sun works, but also revise estimates of mysterious "dark" matter in the universe and strengthen a key challenge to the prevailing theory of particle physics.

  11. Physics

    New probe zooms in on midgets of magnetism

    A new microscope for peering at magnetic materials provides the first glimpses of how such materials behave on a scale of only tens of atoms.

  12. Materials Science

    Scientists get a handle on crystal shape

    Researchers have discovered how the orientation of amino acid molecules can make a growing crystal take on either a right- or a left-handed form.
