BUFFALO, N.Y., Dec. 21, 2009 – Using lasers and a water tank, an engineer hopes to use secrets gleaned from the aerodynamically unconventional flights of hummingbirds and other tiny birds and insects to help design tiny self-propelled flying surveillance devices. The research could also have biomedical and energy applications. Instead of the streamlined flow that occurs when air flows over the wing of a jet, fluid dynamics at the much smaller scale of hummingbird wings are characterized by a swirling, looping flow of air called a vortex, similar to that which is created by canoe paddles as they are pushed through the...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
