VIDEO: Scanner Tells Consumers Nutritional Facts About Food

Called SCiO, the tiny spectrometer allows consumers to scan their food to better understand the physical make-up of the product. For example, SCiO can get nutritional facts, see how ripe the fruit is through a peel and even help farmers figure out the ideal time to harvest.

The small machine relies on spectroscopy, the same kind of light-based technology that astronomers use to determine the composition of stars.
