Superconductivity’s secret ‘broken symmetry’
CORNELL (US)—Scientists have found a “broken symmetry,” where electrons act like molecules in a liquid crystal: Electrons between copper and oxygen atoms arrange themselves differently “north-south” than “east-west.” (more…)

Dawdling electrons move at their own pace
CORNELL (US)—Scientists for the first time have produced images of “heavy fermions”—electrons that move through a conductor as if their mass were up to 1,000 times what it should be. (more…)

Tiny light beam budges nanoscale object
CORNELL (US)—With a bit of leverage, researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That’s enough to completely switch the optical properties of the structure from opaque to transparent, they report. (more…)

Virtual crashes sound like the real thing
CORNELL (US)—When you kick over a garbage can, it doesn’t make a pure, musical tone. That’s why the sound is so hard to synthesize. Now computer scientists have developed a practical method to generate the crashing and rumbling sounds of objects made up of thin “harmonic shells.” (more…)
