Long-eared bats are assisted in flight by their ears and body, according to a study by researchers at Lund University in Sweden. The recent findings improve understanding of the bats’ flying technique and could be significant for the future development of drones etc. Contrary to what researchers previously assumed, Christoffer Johansson Westheim et al show long-eared bats are helped in flight by their large ears.

“We show how the air behind the body of a l...
