Scientists Discover What Makes Sunburns Hurt

Monday, 19 August 2013 | by Pat's Picks

Scientists have discovered what makes a sunburn hurt so much, says the Charlotte Observer. Blame a molecule called TRPV4—a “nightclub bouncer of the cell membrane world.” TRPV4 allows somethings to enter cells and keeps others at bay. Bad news: UV-B rays are one thing it lets in. Good news: Now that researchers have identified this behavior, they are working on a product to block the reaction, something that could potentially quell painful sunburns forever.
