Researchers at Lund University have found that our skin protects us against the harmful ultraviolet rays of the sun by converting the radiations from the rays to heat. This is done through a chemical reaction that releases protons from the molecules of the pigment. This pigment is called Eumelanin. "We found that eumelanin converts harmful UV radiation into heat with almost 100 per cent efficiency. The chemical reaction is incredibly quick, taking less than a thousandth ...Tuesday, 30 September 2014
Skin Uses Projectiles to Protect Against UV Rays
