Cracking the olfactory code in bees

In a new study, researchers present a “cautionary tale?about what may go wrong when using the fledgling science of proteomics to devise a diagnostic test for cancer. In the February 16 issue of the Journal of the National Cancer Institute, researchers from The University of Texas M. D. Anderson Cancer Center detail why an experimental test intended to identify early ovarian cancer from a...

Olfactory system detects pheromones that control reproduction

Howard Hughes Medical Institute researchers have discovered that pheromones essential for mating behavior in mice are recognized by the nose and not by the vomeronasal system, as researchers had long suspected.The new studies demonstrate that the main olfactory epithelium, which was presumed to be mostly involved with the sense of smell, plays a critical role in pheromone detection. Howar...

Evolutionary shifts in olfactory sensitivities in fruit flies

How do an animal's senses change as it evolves to occupy a new ecological niche? By comparing the olfactory system of the fruit fly Drosophila melanogaster, which feeds from multiple fruit types, with that of its sibling species D. sechellia, a specialist particularly drawn to a single fruit type, researchers have demonstrated how evolution can act on several different levels of a sensory system...

Penn study on olfactory nerve cells shows why we smell better when we sniff

Unlike most of our sensory systems that detect only one type of stimuli, our sense of smell works double duty, detecting both chemical and mechanical stimuli to improve how we smell, according to University of Pennsylvania School of Medicine researchers in the March issue of Nature Neuroscience. This finding, plus the fact that both types of stimuli produce reaction in olfactory nerve cel...
