Researchers attached covert feather-inspired flaps to a 3D-printed model airplane wing and mounted it in a wind tunnel to explore the role of covert feathers in bird flight. By precisely measuring how ...

The Wright Brothers studied bird flight before they designed the first airplane. Now modern aircraft fly higher and faster than any bird, yet no manufactured device matches the graceful movements and ...

Postdoctoral researcher Girguis O. Sedky sitting inside of the wind tunnel, showing the covert feather-inspired flaps attached to the 3D-printed model airplane wing. The flaps deploy automatically in ...

Bird wing shape -- a proxy for long-distance flying ability, or dispersal -- is a trait that influences biodiversity patterns on islands around the world, according to biologists. You can know a lot ...
