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.

Some swell materials give up their secret
The discovery of a previously overlooked crystal structure in the best so-called piezoelectric materials may explain their remarkable amount of swelling when zapped by an electric field.

Crystals step up to a new surface
Researchers have made crystals that reversibly change their surface shape when hit by light.

SQUID can catch concealed corrosion
A new technology that can detect corrosion deep within aluminum aircraft parts has revealed that high concentrations of salt don't corrode hidden joints any more than low levels of salt.

Jiggling the Cosmic Ooze
Spurred by the first tentative sightings after a decades-old search, physicists seeking the universe's mass-giving particle — the Higgs boson — have fired up the world's highest-energy particle collider to join the pursuit.

Scientists belt out a novel nanostructure
Researchers have used metal oxides to make microscopic ribbonlike structures that could prove useful for developing future nanoscale devices.

When warming up causes cooling down
Under the right circumstances, heating a tiny cluster of sodium atoms makes its temperature fall.

Physicists get B in antimatter studies
New observations that subatomic particles called B mesons decay differently from their antimatter versions may help explain why the universe is made almost entirely of matter, not antimatter.
