Researchers at University of Tsukuba and their collaborators have conducted a comprehensive analysis of the olfactory ...

Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...

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 ...

While smell plays a considerable role in the social interactions of humans -- for instance, signaling fear or generating closeness -- for ants, it is vitally important. Researchers have found that 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 ...

Firmenich International has patented a high-throughput assay system for identifying compounds that enhance olfactory receptor activity, intensifying the perception of target odorant compounds. The ...

Researchers from Tomsk Polytechnic University, as part of a scientific collaboration, have created nanoactuators to transport ...

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 / ...

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.

Female moths primarily use their sense of smell to find the best host plants on which to lay their eggs, with the deterrent effect of caterpillar feces playing an important role, according to new ...
