Researchers found that the oxybenzone in just a single drop of sunscreen can wreak havoc on fragile coral reef systems. Reefs all over the world are at risk.
Changes in sunscreen labels designed to make them clearer don't seem to be doing the job, a survey finds. Less than one quarter of people knew that SPF value relates to preventing sunburns.
Research suggests that genes that make a natural sunscreen jumped from algae to an ancestor of vertebrates hundreds of millions of years ago. Some animals kept the ability. Others didn't.
