UC Davis researchers identify dominant chemical that attracts mosquitoes to humans
Scientists at the University of California, Davis, have identified the dominant odor naturally produced in humans and birds that attracts the blood-feeding Culex mosquitoes, which transmit West Nile virus and other life-threatening diseases. view more (2009-10-27)
Study examines treatment for olfactory loss after viral infection
Treatment with a glucocorticoid medication, either alone or in combination with Ginkgo biloba, appears to significantly improve the sense of smell in individuals with previous olfactory loss due to upper respiratory infections. view more (2009-10-20)
How the 100th protein structure solved at Diamond impacts our understanding of how insects smell
New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture. view more (2009-09-30)
Researchers unravel mystery behind long-lasting memories
A new study by researchers at Wake Forest University School of Medicine may reveal how long-lasting memories form in the brain. view more (2009-08-12)
Neuroscientists discover long-term potentiation in the olfactory bulb
Ben W. Strowbridge, Ph.D, associate professor of Neuroscience and Physiology/Biophysics, and Yuan Gao, a Ph.D. student in the neurosciences program at Case Western Reserve University School of Medicine, are the first to discover a form of synaptic memory in the olfactory bulb, the part of the brain that processes the sense of smell. view more (2009-05-04)
Creating Ideal Neural Cells for Clinical Use
Investigators at the Burnham Institute for Medical Research (Burnham) have developed a protocol to rapidly differentiate human embryonic stem cells (hESCs) into neural progenitor cells that may be ideal for transplantation. view more (2009-04-14)
A woman's nose knows body odor
It may be wise to trust the female nose when it comes to body odor. According to new research from the Monell Center, it is more difficult to mask underarm odor when women are doing the smelling. view more (2009-04-07)
Female mammals follow their noses to the right mates
Female birds often choose their mates based on fancy feathers. Female mammals, on the other hand, may be more likely to follow their noses to the right mate. view more (2009-03-18)
Study shows males are more tolerant of same-sex peers
Women have traditionally been viewed as being more social and cooperative than men. However, there is recent evidence that this may not be the case. In fact, studies have shown that men maintain larger social networks with other males compared to women and tend to have longer lasting friendships with members of the same-sex than do women. view more (2009-02-12)
Neural mapping paints a haphazard picture of odor receptors
Despite the striking aromatic differences between coffee, peppermint, and pine, a new mapping of the nose's neural circuitry suggests a haphazard patchwork where the receptors for such disparate scents are as likely as not to be neighbors. view more (2009-02-04)
New study by Rice University psychologist finds women's brains recognize, encode smell of male sexual sweat
A new Rice University study published in the Journal of Neuroscience found that socioemotional meanings, including sexual ones, are conveyed in human sweat. view more (2009-01-08)
Moths with a nose for learning
Much like Pavlov conditioned his dog to salivate in anticipation of food when a bell rang, insects can be trained to perform certain behaviors when enticed with different smells. view more (2008-10-03)
MIT paves way to 'artificial nose'
MIT biological engineers have found a way to mass-produce smell receptors in the laboratory, an advance that paves the way for "artificial noses" to be created and used in a variety of settings. view more (2008-09-30)
Nano vaccine for hepatitis B shows promise for third world
Chronic hepatitis B infects 400 million people worldwide, many of them children. Even with three effective vaccines available, hepatitis B remains a stubborn, unrelenting health problem, especially in Africa and other developing areas. view more (2008-08-13)
1 missing gene leads to fruitless mating rituals
Male fruit flies missing a gene for one particular odor receptor become clueless in matters of love, scientists at Duke University Medical Center have discovered. view more (2008-07-24)
'Stuffy nose' mouse: A promise to help treat 31 million with sinusitis
Mice with inflamed nasal tissue being tested at a Johns Hopkins laboratory may be unable to tell if something smells bad or good, but their sensory deficit is nothing to turn up a nose at. view more (2008-07-23)
Scientists find how neural activity spurs blood flow in the brain
New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity. view more (2008-06-26)
Zebrafish enable scientists to study the migration of neurons that enable sexual maturity
Scientists are watching a small group of neurons that enable sexual maturity and fertility make a critical journey: from where they form, near the developing nose, to deep inside the brain. view more (2008-06-05)
New cell-based sensors sniff out danger like bloodhounds
A small, unmanned vehicle makes its way down the road ahead of a military convoy. Suddenly it stops and relays a warning to the convoy commander. The presence of a deadly improvised explosive device, or IED, has been detected by sophisticated new sensor technology incorporating living olfactory cells on microchips mounted on the unmanned vehicle.... view more...

NYU Researchers id new class of photoreceptors,pointing to new ways sights-and smells-are regulated
The identification of a new class of photoreceptors in the retina of fruit flies sheds light on the regulation of the pigments of the eye that confer color vision, researchers at New York University's Center for Developmental Genetics report in a new study appearing in the Public Library of Science's journal, PloS Biology. view more (2008-04-22)
