The sticky geniuses behind Post-Its and Scotch Tape made a polar bear tracker that clings to their fur

Designed by 3M, the ‘Burr on Fur’ polar bear tracker sticks to the animal’s fur, and could be a breakthrough for wildlife research.

In order to protect animals like polar bears from certain threats, whether pollution, climate change, or people, we have to know their behavior. And in order to learn where polar bears live, how they move around, and how many there are, we have to track them. A group of researchers have been working on a new, less invasive way to do this with tags that stick to their fur—rather than collars around their necks or ear tags pierced through their skin.
