Is there anything a smartphone can’t do?

Yesterday, the FDA published new standards for sunscreen labeling:

Sunscreens that don’t protect against both ultraviolet a and B rays and have a sun protection factor, SPF, of at least 15 will have to carry warning label: “This product has been shown only to help prevent sunburn, not skin cancer or early skin aging.”

MIAMI, FL – JUNE 15: Doctor Antonella Tosti, Dermatologist University of Miami School of Medicine, displays an image on her iphone of a mark on the skin of Michael Casa Nova, 12, as she uses it as a dermatoscope while examinging him for symptoms of skin cancer due to sun exposure on June 15, 2011 in Miami, Florida. The federal Food and Drug Administration announced that sunscreen manufacturers are to change the labels on their products to prohibit the use of certain marketing terms. The new rules are meant to help clear up confusion about the meaning of “sun protection factor,” or SPF, and other terms like “waterproof.” (Photo by Joe Raedle/Getty Images)
