Bat wings are like hands: meaty, bony and full of joints. A new study finds that bats take advantage of their flexibility by folding in their wings on the upstroke to save inertial energy. The ...

Evolution has done a pretty good job of producing efficient wings in birds and insects. In particular, natural wings tend to be quite flexible and this allows animals to generate lift and thrust with ...

A team from MIT and NASA led by Neil Gershenfeld is developing a new type of "morphing" wing that rather than using conventional flaps, changes its shape. This new wing is made up of overlapping ...
