GOTHENBURG, Sweden, Feb. 26, 2009 – The mystery of how some marine animals produce light has come one step closer to being solved. Researchers at the University of Gothenburg have discovered that krill, the luminous crustacean, can use special and previously unknown muscles to regulate light intensity. The phenomenon of light emission by living organisms – bioluminescence – is quite common, especially in marine species. It is known that light is generated by chemical reactions in which oxygen molecules play an important part. In the animal world, these chemical reactions take place in special luminescent cells called...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...
