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.

For the first time, researchers have determined how a human olfactory receptor captures an airborne scent molecule, the pivotal chemical event that triggers our sense of smell. Whether it evokes roses ...

Our noses encounter a vast diversity of chemicals every day, but scientists know little of how odorants stir awake the receptors in our bodies. A recent study is the first to parse the structure of a ...

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 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 ...

Olfactory receptors in the mouse nose have been mapped out in unprecedented detail — overturning researchers’ understanding of how noses build a sense of smell. “For 30 years, we’ve taught students ...

Odor molecules are released from wine in a glass and approach the fly nose, the antenna, which is equipped with minute smell hairs, the olfactory sensilla. These contain dendrites of olfactory sensory ...

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 ...

Animal reproduction is supported by the integration of various external and internal processes. These processes include a combination of perceived sensory cues, behaviors and hormone secretion. In ...
