After spending the past decade studying ground-nesting wasps a team of researchers from the Australian National University believe that they've unlocked the secret to the insects' uncanny homing abilities -- one they hope can be applied to future UAV development. Modern, autonomous UAVs have to be laden with high resolution cameras, GPS radios and a slew of other high-tech gadgetry in order to know where they are and where they're going. Wasps, on the other hand, only need their compound eyes and a daily refresher flight.
