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…)
