Both of my parents are Black but have white ancestors. Those recessive white genes were passed on to me, and I was born very light-skinned, with blue eyes and light, wavy hair. This was not a ...
Starscourge Radahn was the child of Radagon - a red-haired champion of the game's Golden Order faction, who worship a cosmic entity known as the Greater Will - and Rennala, queen of the Carians, a group of moon-worshiping nobles and astrologers predating the Elden Ring who draw power from the stars.
Light skin provides better absorption qualities of ultraviolet radiation, which helps the body to synthesize higher amounts of vitamin D for bodily processes such as calcium development. [2] [11] On the other hand, light-skinned people who live near the equator, where there is abundant sunlight, are at an increased risk of folate depletion.
Dark-skinned people, who produce more skin-protecting eumelanin, have a greater protection against sunburn and the development of melanoma, a potentially deadly form of skin cancer, as well as other health problems related to exposure to strong solar radiation, including the photodegradation of certain vitamins such as riboflavins, carotenoids ...
A low-pressure mercury-vapor discharge tube floods the inside of a biosafety cabinet with shortwave UV light when not in use, killing microbes on irradiated surfaces. Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms ...

Human blood in veins is not actually blue. Blood is red due to the presence of hemoglobin; deoxygenated blood (in veins) has a deep red color, and oxygenated blood (in arteries) has a light cherry-red color. Veins below the skin can appear blue or green due to subsurface scattering of light through the skin, and aspects of human color ...
A photolabile protecting group (PPG; also known as: photoremovable, photosensitive, or photocleavable protecting group) is a chemical modification to a molecule that can be removed with light. PPGs enable high degrees of chemoselectivity as they allow researchers to control spatial, temporal and concentration variables with light. Control of ...
