Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and ...

No matter how good our human designs may be, evolution has had a 4-billion-year head start, so there’s no shame in copying off Mother Nature’s homework. Engineers at the University of Bristol have ...

The role of unmanned aerial vehicles (UAVs) has expanded rapidly in both military and civilian circles over the past decade and although most designs to date are miniature versions of conventional ...

Insects are thought to use specific chest muscles to actively open and close their wings. However, high-speed imaging reveals that rhinoceros beetles flap their hindwings to deploy them for flight, ...
