3D-Printed Bomb-Sniffing Dog Noses Could Replace the Real Thing

Dogs are well known for their incredible sense of smell, which is said to be from 10,000 to 100,000 times more acute than ours. Using a vision analogy, what humans can see at a third of a mile, dogs can see just as well more than 3,000 miles away, according to James Walker, former director of the Sensory Research Institute at Florida State University, which conducted studies on the topic.

This ability makes dogs more reliable (and much less invasive) at detecting explosives in airports than human Transportation Security Administration (TSA) agents using high-tech full-body scans and X-rays. Of course, the downside is that while saving human lives, sniffing out explosives is extremely dangerous for the dogs.

Fortunately, a new invention may end the need to use live animals as bomb detectors.
