Bob, sniff them out!
Check out this article titled ‘Make Room for Bomb-Sniffing Humans’. Heres the first paragraph:
When it is necessary to sniff out a trail–be it to a bomb, a drug stash or even to a pie sitting on a windowsill–the task is normally better left to our canine companions. And while our four-legged friends still hold the crown for tracking scents, a new study published in this week’s issue of Nature Neuroscience proves that humans may not be bloodhounds, but they can follow a scent–and they get better with training. In addition, the paper provides evidence that mammals make comparisons between what is sensed by each of their nostrils to synthesize information on scent much the same way that they use both ears to hear.
