Definition of bioluminescence in English:

bioluminescence

noun

  • 1[mass noun] The biochemical emission of light by living organisms such as glow-worms and deep-sea fish.

    • ‘New hatchlings, which instinctively head toward the brightest spot on the horizon, confuse urban lights with the ocean's reflection of moonlight, starlight and bioluminescence in the water.’
    • ‘It is possible that fluorescence in these medusae represents a daylight functional analog of bioluminescence (similar to ‘blanching’ in comb jellies ).’
    • ‘We are cautioned against confusing bioluminescence with fluorescence and phosphorescence.’
    • ‘The chemiluminescent reactions found in living organisms are called bioluminescence.’
    • ‘You can find more books, videos, and software about deep sea life, marine biology, and bioluminescence at the web site above.’
    • ‘This new technology, an imaging method known as in vivo bioluminescence, enables investigators to track changes in the viral population in the same animal day after day.’
    • ‘Ultimately he entered the field experimentally with a study on the pseudoflash with J. W. Hastings, soon to attain prominence in the molecular biology of bioluminescence and circadian biology.’
    • ‘The luminescence was quantified in live cells using bioluminescence imaging.’
    • ‘Rapid control of wound infections by targeted photodynamic therapy monitored by in vivo bioluminescence imaging’
    • ‘In light of their special adaptations related to bioluminescence, buoyancy, crypsis, feeding, intelligence, speed, and vision, they are generally considered to be among the most highly evolved marine invertebrates.’
    • ‘This is because some species are capable of bioluminescence, in which chemicals made by the organism produce light in a chemical reaction.’
    • ‘Dinoflagellate bioluminescence differs biochemically from that of other major luminescent groups.’
    • ‘While it is evident why certain organisms display bioluminescence, some organisms such as mushrooms glow for unknown reasons.’
    • ‘Although its biochemistry is well understood and is applied for various scientific techniques, the survival value of bioluminescence to the organisms themselves often remains unclear.’
    • ‘Chemistry and biophysics of bioluminescence.’
    • ‘How do flows trigger physiological responses such as bioluminescence in organisms, or changes in growth rate, nutrient uptake, and cell structure?’
    • ‘Most studies that report in vivo bioluminescence emission spectra or describe the color of bioluminescence only deal with the adults.’
    • ‘Scientists also have not identified the internal pathways or mechanisms in the organisms that trigger physiological responses to flow, such as bioluminescence and changes in growth rate, nutrient uptake, and structure.’
    • ‘The relatively large shear forces that stimulate dinoflagellate bioluminescence are higher than typical levels of oceanic turbulence.’
    • ‘Some species are capable of producing their own light through bioluminescence, which also makes fireflies glow.’
    1. 1.1 The light emitted by organisms such as glow-worms and deep-sea fish.
      • ‘With transfected cells grown as solid tumors in vivo, the bioluminescence light is emitted shortly after systemic administration of luciferin.’
      • ‘If the source is a bioluminescent searchlight, the ideal reflectance depends on the irradiance of the bioluminescence striking the organism relative to the background radiance.’
      • ‘Examples include incredibly sensitive eyes - designed to pick up even the faintest blue glow of another animal's bioluminescence.’
      • ‘This suggests that directed bioluminescence and the transmission of bioluminescence through gut walls are more important than ambient light for detecting animals at mesopelagic depths.’
      • ‘However, bioluminescence, which is quite rare on land, is found at all depths in the sea, and ranges from a steady glow to flashes of varying duration, frequency and intensity.’
      • ‘It's been pretty well established that some squids use bioluminescence to communicate.’
      • ‘At 150 meters below the ocean surface, all is dark - until the submersible, Alvin, descends into a firestorm of bioluminescence produced by barely visible sea creatures.’
