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.

Pitching Science
A new computer model of baseball pitching helps give pitching robots humanlike abilities and may have enabled engineers to solve a half-century-old puzzle of baseball science.
- Physics
Stretching and twisting a bright idea
A new, stretchy type of liquid-crystal component makes it possible to change a laser's color by simply pulling on the membrane—a much easier, cheaper means of adjustment than that used for today's complex and expensive tunable lasers.

In a squeeze, nitrogen gets chunky
Remarkable already for being a semiconductor and, perhaps, an explosive, a new, solid form of nitrogen made by crushing the ordinary gas to the highest pressures ever also stands out because it continues to survive when the pressure is released.

Electrons trip on tiny semiconductor steps
A first glimpse of how a semiconductor's surface alters electrons' magnetic fields, or spins, suggests that tiny steps in the surfaces are tripping up efforts to create so-called spintronics circuits from semiconductors.

Nanotubes form dense transistor array
Researchers have made an array of transistors out of carbon nanotubes.
