B. Diabetics, put away the bandages: A new technique for checking blood sugar could make finger pricks a thing of the past. Chemists from Northeastern University have developed a method for injecting tiny fluorescent sensors under the skin that detect glucose in the blood. Take a picture of the freckle-size temporary tattoo with a special attachment that fits over your smart phone’s camera lens, and a computer program then analyzes the photo and reports your blood sugar number. The tattoo method is still under-going tests; it could be available in three years.
