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.

Decoding Smell: Demystifying Human Disease and Behavior

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.
