While bomb-sniffing dogs provide an invaluable service, training them using actual explosives can be risky for both the canines and their handlers. A new process could help, utilizing a harmless polymer that quickly absorbs the scent of explosives.

Trained dogs can do a lot of things, but one thing that they can’t do in all situations is hear commands made their handlers. That’s why scientists at Alabama’s Auburn University have created a control system to guide them.
