Smelling a skunk after a cold: Brain changes after a stuffed nose protect the sense of smell
Has a summer cold or mold allergy stuffed up your nose and dampened your sense of smell? We take it for granted that once our nostrils clear, our sniffers will dependably rebound and alert us to a lurking ...

Developing our sense of smell: Biologists pinpoint the origin of olfactory nerve cells
When our noses pick up a scent, whether the aroma of a sweet rose or the sweat of a stranger at the gym, two types of sensory neurons are at work in sensing that odor or pheromone. These sensory neurons are ...
