Ceramics stretch for future applications
Researchers have created a ceramic that stretches to 10 times its original length in record time.

Model may expose how friction lets loose
Rather than just grinding past each other, sliding surfaces may tremble with minuscule ripples that overcome friction as they move along.

Caught in a Flash
View the tip of a snapped towel (which moves faster than the speed of sound), then take a look at a bursting water balloon, a collapsing water drop, a tennis ball in mid-collision with a racket, and many other amazing images in this gallery of high-speed photos snapped by high school students. Sorry! This Web […]

Window Opens into Strange Nuclei
By creating peculiar atomic nuclei that contain not just protons and neutrons but also pairs of rare nuclear particles with so-called strange quarks inside, researchers are shedding new light on the fundamental structure of matter and how it behaves under extreme conditions, as in neutron stars.

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.
