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.

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.

Future brightens for carbon nanotubes
Researchers have made a lightbulb that depends on carbon nanotubes for its glow.

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.

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

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.
