In 2006, Darpa, the Department of Defense's R&D arm, commissioned AeroVironment, a company specializing in remote aircraft, to create an unmanned aerial vehicle (UAV) small enough to fly through an open window. AeroVironment had already built the 4.5-foot-wingspan Raven, which first saw combat over Afghanistan in 2003, but making a UAV so much smaller took five years and 300 different wing designs.
It's the summer, which means swarms of bugs. And if you keep your window open to get cool summer breezes, it means swarms of bugs in your house. Artists James Auger and Jimmy Loizeau have designed a clock that puts those bugs--and the energy created when they're digested by the group's special fuel cell--to work for you.
Groggy fruit flies could lead to the perfect sleeping pill for time-zone hoppers

Geneticist Amita Sehgal of the University of Pennsylvania was recently studying fruit flies in her lab when she noticed something peculiar. The insects slept normally when bathed in light for 24 hours a day but tossed and turned when shifted from one day/night cycle, or â€time zone,â€ to another. It turns out they were suffering from something akin to serious jet lag.
Tiny robotic bulldozers may soon be on their way to Mars.

They'll be too small to clear the way for settlements, but tiny robotic bulldozers may soon be on their way to Mars. Weighing 8 pounds each, the rovers will dig for water or other treasures. Each is equipped with an arm that can scoop Martian soil into an overhead bucket. They're not yet scheduled to fly.
