Unusually White Beetle Gives Scientists Bright Ideas

Facebook X LinkedIn Email
EXETER, England, Jan. 25, 2007 -- An obscure species of beetle could teach scientists how to produce brilliant white ultrathin materials and more efficient white light sources, according to a research team studying the insect.Scientists are expecting the beetle's whiteness to be replicated in synthetic materials and applied to many technological applications. (Images courtesy of P. Vukusic, University of Exeter) The Cyphochilus beetle has a highly unusual brilliant white shell. New research by the University of Exeter and Imerys Minerals Ltd. and published Jan. 19 in the journal Science reveals the secret to this...Read full article

    Glossary
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    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...
    spectrometry
    The study and measurement of spectra and their components.
