A study identifies five women who have a functioning sense of smell despite an apparent lack of olfactory bulbs—the region of the brain that processes odors.

The brain wiring behind scent processing seems to scale across mammalian species.

The introduced cells engrafted in the nose, became olfactory sensory neurons, and sent axons to the animals’ brains.

Lab-grown stem cells fill in for damaged tissue in the noses of mice.

Researchers teamed up with a woman with a keen sense of smell to identify telling differences between healthy people and those with the neurodegenerative disease.

Authors of a small study say the two abilities likely evolved in tandem.

Researchers envision a cochlear implant–like device for the nose to give people with impaired olfaction a sense of smell.

In mice, seeing and smelling food causes immediate cellular changes that ready the liver to convert incoming amino acids to proteins.

The compound engages with a receptor in hair follicle cells and prevents skin cells from dying.
