Physicists trap light in nanoresonators for record time

The reference particle captured light for a time exceeding 200 periods of one wave oscillation, 20-40 times longer than usual. This opens new perspectives in such areas as manufacturing compact sensors, night vision devices, and optical data transmission.

Magnetic microrobots use capillary forces to coax particles into position

New research shows how simple, microscopic robots, remotely driven by magnetic fields, can use capillary forces to manipulate objects floating at an oil-water interface.
