Bat's powerful lift is illuminated by fog

Technique shows how bats and insects share the secret of slow flight.

Bats have a clever aerodynamic trick to make flying easier, researchers have found: the sharp edge at the front of their wings cuts through the air in such a way as to create a vortex on top of the wing, producing up to 40% of the lift needed to stay aloft.

“It explains how these animals are able to fly at very slow speed,” says Anders Hedenström from Lund University in Sweden, who led the research — published in Science1 — that showed the effect with a live bat.
