"Although the cells of the retina themselves don't renew, the light sensitive parts do," explained Professor Marshall, pointing to the turnover of discs of photosensitive pigment. As the eye ages, its ability to dispose of waste products deteriorates and the old discs are not cleared away but buried in a sort of biological landfill for old pigment within the cells below.
If we're exposed to sunlight, its ultraviolet rays will oxidize the melanin (a photosensitive pigment) in our skin.
Algae are used in the biofuel production and this research would increase its value addition where they could be cultured for their photosensitive pigments. Furthermore, this would highlight the importance of high biodiversity in Brunei Darussalam.
Plants perceive light with photosensitive pigments, just as humans do.
If we understand how photosensitive pigments respond to specific wavelengths of light, we will better understand how to improve or change the light quality and thus affect growth and flowering.
These structures are packed to the extreme with photosensitive pigments to capture as many photons as possible in the animals' light-starved environment.
