We summarize the week's scientific breakthroughs every Thursday.
- Materials Science
Scientists tone down silicon rockers
Researchers have created pairs of silicon atoms that stay level instead of slowly rocking in place, permitting scientists to study silicon-surface reactions in unprecedented detail.
- Materials Science
High-temperature ceramics takes flight
A recent NASA flight test of ultrahigh-temperature ceramic materials might lead to a new aerospace design that would make the space shuttle look downright old-fashioned.
- Physics
Protons may waltz off nuclear dance floor
Detection of proton pairs simultaneously emitted from neon nuclei raises the possibility that a new and long-sought window into the nucleus has been found and unlocked.
- Materials Science
New work improves stainless steel surface
A novel electrochemical method improves the surface of stainless steel without making the metal brittle or prone to corrosion.
- Physics
Solid-state insights yield physics Nobel
The 2000 Nobel Prize in Physics went to three scientists and inventors whose work laid the foundation of modern information technology, particularly through their invention of rapid transistors, laser diodes, and integrated circuits.
- Physics
Electron cloud mirrors fossil life-form
Remarkable molecules whose electron clouds would resemble now-extinct marine creatures called trilobites could appear in experiments on ultracold atom clouds known as Bose-Einstein condensates, theorists predict.
- Physics
Goo’s melting could keep battery cool
Using the sometimes dangerous heat of lithium batteries to melt wax or similar materials may keep the potent cells cool enough for safe use in electric vehicles while also boosting the batteries' performance.

One-molecule chemistry gets big reaction
Carrying out a widely used chemical reaction on one molecule at a time, researchers demonstrate unprecedented control of molecular behavior and, possibly, the ability to make novel nanotechnology devices and compounds that can't be created with ordinary chemistry.
- Physics
Electron breakup? Physics shake-up
A controversial theoretical proposal that challenges more than a century of theory and experiments suggests that loose electrons in liquid helium may break into pieces, dubbed electrinos.
- Physics
Most-Wanted Particle Appears, Perhaps
Hints of the Higgs boson—the crucial and last undetected fundamental particle predicted by the central theory of particle physics—have cropped up at a particle collider in Switzerland just as the machine is slated to be dismantled to make room for a more powerful collider.
- Physics
Electrons get a crack at the nucleus
As long suspected but never before shown, electrons orbiting an atom can directly excite the atom's nucleus.
