The muscles in bats’ wings are much cooler than the muscles in their core. The finding could one day enhance our understanding of human muscle.

Crowded conditions prompt pea aphids to have offspring with wings. Viral genes in the insects' genomes let that happen, research finds.

The way fruit flies grow their wings could one day help diagnose and treat human genetic diseases.

The perfect wing shape not only makes for faster flying, but could also help us generate more energy from water.

Many butteflies use their wings to mimic other species to protect themselves from predators. Now, a new study shows how just one gene is key to their color.
