We summarize the week's scientific breakthroughs every Thursday.
- Materials Science
Getting Out the Thorn
Researchers are developing new ways to improve the compatibility of implantable biomaterials in the body.
- Materials Science
Can ancient stone avoid salt attacks?
Researchers have found that a polymer coating can protect stone from damage caused by growing crystals.
- Materials Science
Carbon nanotubes turn on water flow
Computer simulations show that water molecules will quicklye nter and flow along a carbon nanotube just 8 nanometers in diameter.
- Materials Science
Bonds make a sacrifice for tough bones
Researchers report that easily broken bonds in collagen may help prevent bones from easily fracturing.
- Materials Science
Synthetic molecules mimic bone growth
Researchers have created molecules that assemble into a microscopic structure that mimics bone.
- Physics
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.
- Physics
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.
- Physics
Mishap halts work at Japanese neutrino lab
A costly accident has indefinitely disabled Super-Kamiokande, a cutting-edge neutrino detector in Japan.
- Physics
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.
- Physics
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.
- Materials Science
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.
- Materials Science
Tiny detector finds hydrogen better
Researchers have made a miniature device that can quickly detect hydrogen leaks.
