Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings, allowing them to hunt and capture their prey in silence.  And owls are vicious. Imagine the Go Pro footage you would get if you stuck one of those on an owl for the evening. A research group working to solve the mystery of exactly how owls achieve this acoustic stealth presented their findings at the American Physical Society's (APS) Division of Fluid Dynamics meeting over the weekend in Pittsburgh and hope their work on "silent owl technology" will help the design of aircraft, wind turbines, and submarines.  read more
