Researchers in Glasgow have developed an early warning sunburn indicator. A thin paper strip or sticker, filled with "intelligent ink," will turn pink after too much exposure to ultra-violet light. The device is easy to use, too: Before heading to the beach, strap on the bracelet or sticker and when you see it turn pink, it is time to put on a shirt or head indoors. The strips are inexpensive enough for frequent use and researchers are hoping to test the prototype this summer. We're learning more about this shiny new development with Andrew Mills, professor at Strathclyde University, who helped to create these sunburn wristbands.
