How migrating birds 'run a marathon,' burning muscles and organs in long flights
Migrating birds complete long non-stop flights of many hours for songbirds and days for some shorebirds to reach breeding or wintering grounds. During such flights a bird's metabolic rate is very high, fueled by stored fat, ...

Fluctuating forces of flight captured by new, high-tech paint
As it thunders upward through the Earth's atmosphere to carry a spacecraft into orbit, a rocket is buffeted by a chaotic flow of air. At high speeds, airplanes experience a similar, unsteady flow of air over their wings. ...
