Bats save energy by drawing in wings on upstroke: study

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

Scientists find a key to growth differences between species

The tiny, little-noticed jewel wasp may provide some answers as to how different species differ in size and shape. And that could lead to a better understanding of cell growth regulation, as well as the underlying causes ...

Flight Artists film smallest insect in flight

The Flight Artists team from Wageningen University, the Netherlands, has been the first to make high-speed camera footage of parasitic wasps of about 1 mm wingspan.

Evolution in reverse: insects recover lost 'wings'

The extravagant headgear of small bugs called treehoppers are in fact wing-like appendages that grew back 200 million years after evolution had supposedly cast them aside, according to a study published Thursday in Nature.

Micro flying robots can fly more effectively than flies

There is a long held belief among engineers and biologists that micro flying robots that fly like airplanes and helicopters consume much more energy than micro robots that fly like flies. A new study now shows that a fly ...
