Definition of bioluminescence in English:

bioluminescence

noun

  • 1The biochemical emission of light by living organisms such as fireflies and deep-sea fishes.

    • ‘The luminescence was quantified in live cells using bioluminescence imaging.’
    • ‘While it is evident why certain organisms display bioluminescence, some organisms such as mushrooms glow for unknown reasons.’
    • ‘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.’
    • ‘This is because some species are capable of bioluminescence, in which chemicals made by the organism produce light in a chemical reaction.’
    • ‘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.’
    • ‘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.’
    • ‘The relatively large shear forces that stimulate dinoflagellate bioluminescence are higher than typical levels of oceanic turbulence.’
    • ‘We are cautioned against confusing bioluminescence with fluorescence and phosphorescence.’
    • ‘The chemiluminescent reactions found in living organisms are called bioluminescence.’
    • ‘It is possible that fluorescence in these medusae represents a daylight functional analog of bioluminescence (similar to ‘blanching’ in comb jellies ).’
    • ‘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.’
    • ‘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.’
    • ‘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.’
    • ‘How do flows trigger physiological responses such as bioluminescence in organisms, or changes in growth rate, nutrient uptake, and cell structure?’
    • ‘Dinoflagellate bioluminescence differs biochemically from that of other major luminescent groups.’
    • ‘Chemistry and biophysics of bioluminescence.’
    • ‘Rapid control of wound infections by targeted photodynamic therapy monitored by in vivo bioluminescence imaging’
    • ‘Some species are capable of producing their own light through bioluminescence, which also makes fireflies glow.’
    • ‘Most studies that report in vivo bioluminescence emission spectra or describe the color of bioluminescence only deal with the adults.’
    1. 1.1 The light emitted by organisms such as fireflies and deep-sea fishes.
      • ‘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.’
      • ‘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.’
      • ‘Examples include incredibly sensitive eyes - designed to pick up even the faintest blue glow of another animal's bioluminescence.’
      • ‘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.’
      • ‘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.’
