1. What’s in your food?
SCiO is a pocket molecular sensor. Shine its little light on your food (or really most anything) and it will send your smartphone data about what’s in it. In the case of food, it can tell you about the quantity of calories, sugar, protein and other factors. It only really works on single objects, so while it could tell you the chemical makeup of each ingredient in a salad, it can’t tell you about the entire salad in one go. The sensor could be useful for dieters, amusing for amateur chemistry buffs and potentially life-saving for people with special dietary concerns, such as diabetics. The sensor itself costs $249, and you’ll need a smartphone app with a monthly subscription. They hope to begin shipping later this year.
