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…)

Staging a nanoscale disappearing act

CORNELL—Researchers have developed a device that can make it seem that a bump in a carpet—or, indeed, any flat surface—isn’t there. So far the illusion works only at the nanoscale, but the researchers from Cornell University suggest that the basic principle might eventually be scaled up for military and communications applications, or perhaps used in reverse to concentrate solar energy.
