Magnets, not magic, make gas bulbs bad
Once as baffling as black magic, the random failures of glass bulbs used in magnetic resonance imaging (MRI) now appear to stem from unexpected magnetization of the glass.

Path to new elements now looks steeper
Making novel, superheavy elements is harder than was previously expected, according to a new experiment, but the findings may also help physicists better choose which atoms to smash into which.

Constant Changes
Evidence from the early universe that one of the so-called constants of nature, known as alpha, was once slightly smaller than it is today hints that the laws of physics themselves may vary over time and space.

Atomic Crowds Tied by Quantum Thread
Quantum states of record numbers of atoms—entire atom clouds—get blended together by physicists wielding a new, relatively simple technique in quantum telecommunications and computing.

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.
