Once considered anosmic, birds are now widely recognized as using olfactory cues to aid in a wide range of behaviors.

A study finds that the odorless compound hexadecanal, or HEX, increases aggressive behavior in women but has a calming effect on men.

The temporary loss of olfaction stops the flies from eating any more of whatever it is that made them sick.

Good girl, Florin!

In a proof-of-concept study, researchers used dogs’ diagnoses of prostate cancer to inform a machine learning algorithm with the goal of one day detecting cancers with canine-level accuracy.

Using optogenetics, scientists have simulated the sense of smell directly within the mouse brain to investigate the nature of olfactory perception.

Data from a crowdsourcing smartphone app is helping to track the spread of the disease in real time and reveals the symptom as the number one indicator of infection.

In a virtual reality experiment, participants recovered faster from a small electric shock when they could smell natural scents than when they could smell urban odors.

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.

The parasite changes people’s scent, primarily due to an increase in aldehydes.
