Olfactory receptors are integral to sensory perception, forming a sophisticated system that enables organisms to detect and differentiate an immense variety of volatile chemical compounds. As members ...
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 ...
Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...
New research from the Champalimaud Foundation (CF) reveals how missing just one essential amino acid can change gene ...
Even creatures that live underwater, like sharks, are known to have a strong sense of smell. Sharks can detect scents that ...
Scientists discover a “runaway bulldozer” in ant DNA that silences smell genes, keeping chemical communication - and colony ...
Ants have evolved an acute sense of smell, which requires each sensory neuron to choose one scent receptor out of hundreds.
Our noses can effortlessly distinguish the aroma of coffee from the tang of gasoline, yet how they do it has long been a mystery. In a study that appears Oct. 30 in Nature, scientists at Duke ...
When fruit flies lack essential amino acids, their brains rewire their sense of smell to help them find food rich in the nutrients they need.
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 / ...
