Zhou's team published its findings Monday in the journal Nature Human Behaviour.. Human's sense of smell is nowhere near that of many animals, such as dogs. But it may not be as sluggish as most ...

And that understanding can also lead to new technologies, just as understanding vision in nocturnal animals contributed to the development of night vision goggles. “The fact that we were oblivious to ...
