Bonds make a sacrifice for tough bones
Researchers report that easily broken bonds in collagen may help prevent bones from easily fracturing.

Synthetic molecules mimic bone growth
Researchers have created molecules that assemble into a microscopic structure that mimics bone.

Shortest transistor makes its debut
A novel type of single-molecule transistor built around a one-molecule-thick layer of organic molecules may eventually lead to faster, denser chips because the channel through which electrons flow is so short.

Neutrino shortage may signal new force
The dearth of neutrinos from a precision experiment casts some doubt on the prevailing model of particle physics and may indicate that a previously unrecognized extra force exists.

Mishap halts work at Japanese neutrino lab
A costly accident has indefinitely disabled Super-Kamiokande, a cutting-edge neutrino detector in Japan.

The Brazil nut effect gets more jumbled
New and puzzling evidence for why big particles bob to the top when mixtures of granular materials are shaken-the so-called Brazil nut effect-emerges from an experiment showing that even the air between grains plays a role.

Nobel prize: Physics
Three scientists have jointly won the 2001 Nobel Prize in Physics for creating the first samples, 6 years ago, of a long-sought and strange state of matter called a Bose-Einstein condensate.

Adhesive loses its stick with heat
A new type of epoxy adhesive loses its stickiness when heated, allowing easy separation of materials that were once tightly bonded.

Tiny detector finds hydrogen better
Researchers have made a miniature device that can quickly detect hydrogen leaks.

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.
