Owls produce negligible noise while flying. While many studies have linked the micro-fringes in owl wings to their silent flight, the exact mechanisms have been unclear. Now, a team of researchers has ...

Ms. Ackerman is the author of “What an Owl Knows: The New Science of the World’s Most Enigmatic Birds,” from which this essay is excerpted. When the first lucky observers spotted Flaco, the Eurasian ...

Owl-inspired innovations can reduce noise by as much as 10 decibels, similar to the difference in noise between a passing truck and a passing car. Ed MacKerrow / In Light Of Nature Every owl fancier ...

A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

Many species of owl are able to hunt without being heard by their prey by suppressing the noise of their wings at sound frequencies above 1.6 kilohertz (kHz) -- including the range at which human ...

To the ancient Greeks, the owl symbolized wisdom, but the Romans saw it as an evil omen. Their myths tell of an owl-like strix that stalked the night and preyed on human flesh. Ovid’s poem Fasti ...

Researchers have formulated a mathematical solution that could help minimize noise, maximize aerodynamics in design of porous airfoils (2-D wings) to improve wind turbines and air vehicles. Many ...
