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.

Inorganic tubes get smaller than ever
Researchers have created the smallest stable, freestanding inorganic nanotubes yet.
- Materials Science
Novel nanotubes are now made-to-order
Researchers have made nanotubes with specific sizes and traits by designing molecules that self-assemble.

Surface reaction recorded in real time
Ultrafast laser pulses may have for the first time revealed the incredibly rapid, step-by-step progress of a complete chemical reaction on a surface, at the actual speed at which it took place.

Cold sliver may sense electron quiver
By detecting vibrations of less than an atom's width of a tiny cantilever, physicists have made the most sensitive measurement of force ever by mechanical means.

Moon may radio cosmic rays’ biggest hits
Efforts to use the moon to detect the highest-energy cosmic rays get a boost from an experiment showing that gamma rays zipping through a giant sandbox cause the kind of microwave bursts moon-watchers are hoping to see.

Frigid ‘dynamite’ assembles into superatom
Although it's now the fifth element to be made into the strange state of ultracold matter known as Bose-Einstein condensate, helium may prove to be the most revealing so far because of unusually high energies within the newly condensed atoms.
