Unique study shows how bats maneuver

For the first time, researchers have succeeded in directly measuring the aerodynamics of flying animals as they maneuver in the air. Previously, the upstroke of the wings was considered relatively insignificant compared to the powerful downstroke but, in a new study, biologists have observed that it is on the upstroke of the wings that bats often turn.
