Humans Track 33-Foot Chocolate Trail

Just like a skilled bloodhound, humans are able to track scents…like a 33-foot chocolate trail. The University of California, Berkeley is doing research to find out “whether mammals compare information coming from their two nostrils in order to aid scent-tracking performance.”



What they found was that not only do humans use both nostrils but, with training, “they can improve their accuracy significantly while nearly doubling their speed along the scent trail.”

I don’t know about you, but this is the kind of experiment I could participate in. Especially if you got to eat the chocolate at the end of the trail…very motivating!
