An international team of scientists led by UC San Francisco researchers has mapped out the genetic trajectories taken by melanoma as it evolves from early skin lesions, known as precursors, to ...

Many people lather up with sunscreen or cover up with hats to protect themselves from the sun’s harmful rays. These added layers help to shield the skin from ultraviolet (UV) light, which damages DNA ...

Ultraviolet radiation, a high-frequency form of energy from the sun, is classified in the same risk category as X-rays and nuclear radiation. As temperatures and sun exposure increase, experts at the ...

Scientific consensus on the biological mechanisms underpinning sunburn has remained largely unchanged for decades. The ...

Sunburn has traditionally been attributed to UV-induced DNA damage. However, a new study reveals that RNA, another vital cellular molecule, plays a major role in triggering acute sunburn reactions.
