Scientists create DNA tracking tags, might soon be used to track protesters as well as animals

Researchers at the University of Aveiro in Portugal are developing DNA barcode tags that can be harmlessly applied to a wide variety of products, even foods or liquids. Each tag is a unique combination of DNA base pairs that attach to most surfaces, and can later be collected, amplified, and sequenced, to reveal the history of the object they mark.
