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.

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 ...

For roughly 30 years, biology students have learned the same tidy diagram of the inside of the nose: four broad zones, each ...

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 ...

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 ...

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 ...

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 ...

For most of us, the sense of smell is an integral part of everyday life; it plays a critical role in providing information about our surroundings, alerting us to potential dangers, enhancing our sense ...

From the ability to detect the smell of wet soil to the scent of ripe fruit, the human olfactory system has evolved over thousands of years in response to how people live and what they eat, according ...
