An unmanned Pelican quadrocopter recently broke the endurance record for laser-powered hovering after spending more than 12 hours airborne. That crushes the previous record of six hours of laser-beam-powered flight.
New studies on bats and bluegill sunfish add to scientists' knowledge of a rare and enviable trait
