A team of chemical and biological engineers at Seoul National University in the Republic of Korea has developed a proof-of-concept device that could one day lead to the creation of an artificial nose.

The way that the sense of smell works is that olfactory sensory neurons (OSNs) are wired up to olfactory receptors (ORs) in the nasal epithelium, from which they send signals to the brain. Once ...

A research team led by scientists at Columbia’s Zuckerman Institute used techniques including single cell genomics, to describe a previously undetected RNA-mediated mechanism in mice that could ...

A new study published in Cell titled, “A spatial code governs olfactory receptor choice and aligns sensory maps in the nose and brain,” led by researchers from Harvard Medical School (HMS) has created ...

Humans have about 400 odorant receptors (ORs), but scientists have had trouble finding ligands that match up with most of these ORs in lab settings—leaving them with a murky understanding of how ...

The human olfactory system discriminates between thousands of odours by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different ...

A research team has presented a roadmap for developing an "artificial olfactory system" that detects odors like the human ...

Some fish come onto the land to hunt or move around. Typically, this behavior happens at nighttime, as seen in eels, for instance. In the new study, researchers have found that such amphibious fishes ...
