Cynthia Graber reports on a skin patch developed by Israeli scientists that warns you when you’re getting too much sun – before you start to burn.


GRABER: It's summer time, and for many folks that means sunburn time. Scientists say incidents of sunburn and skin cancer have been on the rise as manmade chemicals thin the protective ozone layer. Until now, the only way to tell how much sun is too much is after the damage is done. But Israeli scientists have come up with a solution, a sticker that warns you before you burn. It measures ultraviolet radiation, the kind that causes burns and most skin cancers. It's a little round patch that contains chemicals that slowly turn color before your skin does, letting you know it's time to get into the shade or reapply sunscreen. The sticker works with sunscreen, absorbing it and factoring in the protective power of your sunscreen with your skin type. There are different color stickers that work with different skin types, so you can coordinate your beach wear with your sun protection. And that's this week's technology update. I'm Cynthia Graber.
