Definition of bioluminescence in English:

bioluminescence

noun

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

    • ‘The relatively large shear forces that stimulate dinoflagellate bioluminescence are higher than typical levels of oceanic turbulence.’
    • ‘Chemistry and biophysics of bioluminescence.’
    • ‘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.’
    • ‘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.’
    • ‘While it is evident why certain organisms display bioluminescence, some organisms such as mushrooms glow for unknown reasons.’
    • ‘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.’
    • ‘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.’
    • ‘The chemiluminescent reactions found in living organisms are called bioluminescence.’
    • ‘This is because some species are capable of bioluminescence, in which chemicals made by the organism produce light in a chemical reaction.’
    • ‘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 luminescence was quantified in live cells using bioluminescence imaging.’
    • ‘Rapid control of wound infections by targeted photodynamic therapy monitored by in vivo bioluminescence imaging’
    • ‘Most studies that report in vivo bioluminescence emission spectra or describe the color of bioluminescence only deal with the adults.’
    • ‘It is possible that fluorescence in these medusae represents a daylight functional analog of bioluminescence (similar to ‘blanching’ in comb jellies ).’
    • ‘Dinoflagellate bioluminescence differs biochemically from that of other major luminescent groups.’
    • ‘How do flows trigger physiological responses such as bioluminescence in organisms, or changes in growth rate, nutrient uptake, and cell structure?’
    • ‘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.’
    • ‘You can find more books, videos, and software about deep sea life, marine biology, and bioluminescence at the web site above.’
    • ‘We are cautioned against confusing bioluminescence with fluorescence and phosphorescence.’
    • ‘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.
      • ‘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.’
      • ‘With transfected cells grown as solid tumors in vivo, the bioluminescence light is emitted shortly after systemic administration of luciferin.’
      • ‘It's been pretty well established that some squids use bioluminescence to communicate.’
      • ‘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.’
      • ‘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.’
      • ‘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.’
