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 ...

A bird banking in a crosswind doesn't rely on spinning blades. Its wings flex, twist and respond instantly to its environment ...

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 ...

A major new theory for the evolution of flight is changing textbooks around the world. It involves wing-assisted incline running and a fundamental bird wing angle. One of the scientists who led the ...
