Unlocking the secret of the owl's silent flight (IMAGE)

"The owl wing has a serrated leading edge, a porous and compliant trailing edge, and a velvety surface composed of flexible interlocking fibers that look like a jungle canopy when viewed under a microscope," says Lehigh University's Justin Jaworski, an associate professor of mechanical engineering. "One part of my work has investigated how owls may cleverly use the effects of elasticity and porosity at their wing edges to reduce noise."
