Insects evolved radically different strategy to smell
Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn. view more (2008-04-14)
'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)
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)
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)
How odors are sensed: A complex system clarified
Yale scientists have systematically plotted the responses of the entire Drosophila (fruit fly) olfactory system, providing the first multi-dimensional map of the range of odorants sensed and the regions of the brain that are stimulated. view more (2006-04-13)
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)
Study identifies pathway required for normal reproductive development
Massachusetts General Hospital (MGH) clinical researchers, in collaboration with basic scientists from the University of California, Irvine (UC Irvine) have identified a new molecular pathway required for normal development of the reproductive, olfactory and circadian systems in both humans and mice. view more (2007-10-16)
Common algae helps illustrate mammalian brain electrical circuitry
Mice whose brain cells respond to a flash of light are providing insight into the complexities of the sense of smell and may ultimately yield a better understanding of how the human brain works. view more (2007-04-19)
Psychologist Says Neurochemical Processes Explain Romantic Attraction
The Beatles' George Harrison wondered in his famous love song about the 'something' that 'attracts me like no other lover.' view more (2007-02-13)
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)
Pheromone from mother's milk may rapidly promote learning in newborn mammals
By studying the ability of newborn rabbit pups to learn the significance of new odors, researchers have found that a mammary pheromone secreted in mother's milk may act as a chemical booster that facilitates the ability of pups to quickly associate environmental odors with the opportunity to nurse. view more (2006-10-10)
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)
There's no scent like home
Tiny larval fish living among Australia's Great Barrier Reef spend the early days of their lives swept up in ocean currents that disperse them far from their places of birth. view more (2007-01-09)
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)
Honey bee chemoreceptors found for smell and taste
Honey bees have a much better sense of smell than fruit flies or mosquitoes, but a much worse sense of taste, according to researchers at the University of Illinois at Urbana-Champaign. view more (2006-10-26)
Remembrance of smells past: how the brain stores those meaningful memories
Smells trigger memories but can memories trigger smell, and what does this imply for the way memories are stored? A UCL study of the smell gateway in the brain has found that the memory of an event is scattered across sensory parts of the brain, suggesting that advertising aimed at triggering memories of golden beaches and soft sand could well... view more...

Carnegie Mellon study reveals that odor discrimination is linked to the timing at which neurons fire
Timing is everything. For a mouse trying to discriminate between the scent of a tasty treat and the scent of the neighborhood cat, timing could mean life or death view more (2006-11-08)
Spinal cord repair: pilot trials "within sight"
When the brain and spinal cord are injured, the damage is permanent, because the tissues cannot repair themselves in the way that bone and skin can. Writing in the June Journal of the Royal Society of Medicine, Dr Geoffrey Raisman describes encouraging results from a new approach to the problem, which he believes will make it possible to plan a... view more...

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 discover stem cell 'guide' that may be key for targeting neural stem cell treatments
UC Irvine School of Medicine researchers have discovered how new neurons born from endogenous neural stem cells are sent to regions of the brain where they can replace old and dying cells, a finding that suggests how stem cell therapies can be specifically targeted to brain regions affected by neurodegenerative diseases or by stroke. view more (2005-06-24)
