Bioluminescence is observed even in some marine bacteria, which emit a steady light once they have attained a certain level of concentration of organic particles, a state known as quorum sensing. Now, researchers at the Hebrew University of Jerusalem have discovered that light emitted by the ...
The measured light is dominated by flashes over a very faint ambient background. The median light levels follow an exponential scaling law below 2000 m and decrease at the rate of 1/e per kilometer. Stimulated bioluminescence is observed in the wake of the instrument, even at depth....

Bioluminescence, created by a chemical reaction, can be used to find or attract food, mates, or avoid predatory attacks. The spectacle has been observed inseveral hundred speciesmany of which are marine. While in numerous cases bioluminescence has been conserved and passed down through related spec...
How and why bioluminescenceoccursis not fully understood; however, in the undersea realm, it appears to be used in a variety of interesting and ingenious ways. The most commonly observed form of bioluminescence in the sea is the pinpoint sparking of light at night that can create cometlike tr...

Bioluminescence has been observed in 11 halocyprid ostracod species, and the sites of secretion are described. Bioluminescence in cypridinid ostracods has been thoroughly investigated (Harvey, 1952). However, since the original suggestion that the edge glands in the carapace of halocyprid ostracod...
The production of luminous clouds has been observed in the Oplophoridae, Pandalidae and Thalassocarididae of the Caridea, and in the Penaeidae of the Penaeidea (Table 1). Observations of the luminescence of specific light organs or tissues are much less numerous. Luminescence has been ...
leaving most of the ocean environment in perpetual darkness. Yet even shallow ocean waters, dark only at night, harbor luminous organisms. In an extensive study off the California coast, 76% of all individual animals (in 553 taxa) observed between the surface and a depth of 3900 m are known...
Injection of cells in the suprarenal aorta showed diffuse distribution of cells in normal animals, whereas distinct localization to the kidneys was observed in mice with ischemia- and reperfusion-induced acute kidney injury (AKI). Intrajugular infusion of MSCs demonstrated predominant accumulation of ...
