from public places. Now scientists have suggested that drones, as well as wind turbines and planes, could learn something from owls. Sponsored By designing an aerofoil with the cross section of an owl wing and the same structure formed by the feathers along its trailing edge, researchers have calculated that they can reduce the noise of artificial wings.
