A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily.

IN 1950, Wald, Durell and St. George 1 found a shift of the absorption maximum in a rhodopsin-glycerin mixture illuminated at − 73° C., and they proposed lumi-rhodopsin as the first intermediate in ...

Photoreceptor cells in our eyes can adjust to both weak and strong light levels, but we still don't know exactly how they do it. Researchers now revealed that the photoreceptor protein rhodopsin forms ...

Regeneration of rhodopsin, which completes the rhodopsin cycle described in the following article, occurs spontaneously if the retina of the rat is isolated and sealed in a small chamber.

Any living organism that directly harnesses the sun's energy uses one of three types of energy-converting pigments: chlorophyll, which gives plants their green color, bacteriochlorophyll, or retinal ...
