Humans Can Scent-Track, Too!

Look closely, that’s not a dog … it’s a human (wearing a blindfold, earplugs and gloves) following a scent trail through the grass:

In a paper appearing this week in the advance online edition of Nature Neuroscience, UC Berkeley researchers report conclusive evidence from these experiments that humans do indeed gain a performance advantage from cross-nostril comparisons. They also found that humans can scent-track, and that, with training, they can improve their accuracy significantly while nearly doubling their speed along the scent trail.
