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 ...

Researchers have for the first time identified the function of olfactory receptors in the human heart muscle, such as are also present in the nose. One of the receptors reacts to fatty acids that ...

A team of scientists from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has now discovered that the odorant receptor OR5K1 is specialized to recognize pyrazines ...

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.

Recognizing foods, predators, and pests by their smell is of key evolutionary significance in many species, including humans. Smell relies on molecular recognition—the precise binding of a volatile ...

A wide variety of chemicals having distinct odors are smelled by humans. Odor perception initiates in the nose, where it is detected by a large family of olfactory receptors (ORs). Based on divergence ...

It’s clear that genes, receptors and neurons all play a role in detecting odors. But much of how we make sense of what we sniff remains mysterious. A neuroscientist explains. By Daniela Hirschfeld / ...

Duke lab built Neanderthal, Denisovan smell receptors, tested them in a dish DURHAM, N.C. – If you had the grooming habits of a Neanderthal, perhaps it’s a good thing your nose wasn’t as sensitive to ...

A team of scientists from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has now discovered that the odorant receptor OR5K1 is specialized to recognize pyrazines ...

The research article, “Ni-rGO Sensor Combined with Human Olfactory Receptor-Embedded Nanodiscs for Detecting Gas-Phase DMMP as a Simulant of Nerve Agents,” was published in ACS Sensors. Gas sensors ...
