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.

Chemical sensors gain true portability
Researchers have designed simple new films for indicating the presence of worrisome airborne chemicals.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
