You'll never look at hummingbirds the same again. The Pentagon is pouring millions of dollars into the development of tiny drones inspired by biology, each equipped with video and audio equipment that can record sights and sounds.
They could be used to spy, but also to locate people inside earthquake-crumpled buildings and detect hazardous chemical leaks.
The smaller, the better.
Researchers are even exploring ways to implant surveillance and other equipment into an insect as it is undergoing metamorphosis. They want to be able to control it.
The devices could end up being used by police officers and firefighters.
Their potential use outside battle zones, however, is raising questions about privacy and the dangers of the winged creatures buzzing around in the same skies as aircraft.
