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)
Genetic variant linked to odor perception
Why the same sweaty man smells pleasant to one person and repellant to another comes down to the smeller's genes. view more (2007-09-17)
Olfactory nerve cells expressing same receptor display a varied set of reactions
n a mouse model, University of Pennsylvania School of Medicine researchers discovered that olfactory sensory neurons expressing the same receptor responded to a specific odor with an array of speeds and sensitivities. view more (2006-02-03)
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)
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)
Wake up and smell the sweat
Some people are oblivious to the odor in the locker room after a game, while others wrinkle their noses at the slightest whiff of sweat. view more (2007-11-26)
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)
Knocking nanoparticles off the socks
Scientists in Switzerland are reporting results of one of the first studies on the release of silver nanoparticles from laundering those anti-odor, anti-bacterial socks now on the market. view more (2009-10-29)
Kids connect alcohol odors with mom's emotions
How children respond to the smell of alcoholic beverages is related to their mothers' reasons for drinking, according to a new study from the Monell Chemical Senses Center. view more (2008-06-25)
Two 'noses' are necessary for flies to navigate well
Animals and insects communicate through an invisible world of scents. By exploiting infrared technology, researchers at Rockefeller University just made that world visible. view more (2007-12-27)
New research shows sharks use their noses and bodies to locate smells
Sharks are known to have a keen sense of smell, which in many species is critical for finding food. However, according to new research from Boston University marine biologists, sharks can not use just their noses to locate prey; they also need their skin - specifically a location called the lateral line. view more (2007-05-30)
Sniffing out danger
Each human nose encounters hundreds of thousands of scents in its daily travels perched front and center on our face. Some of these smells are nearly identical, so how do we learn to tell the critical ones apart? view more (2008-03-28)
Growth hormone found to have new role in development of brain's smell center
A human hormone known to stimulate the growth of cells throughout the body has a new role - helping to set up the proper nerve connections in the odor center of the brain, according to University of California, Berkeley, scientists. view more (2008-03-27)
Bid to help students with visual impairment
Marianna Buultjens and Phil Odor will link with Heather Mason of the University of Birmingham to examine 'real world' case studies, collaborating with the University of Edinburgh's Media and Learning Technologies Service (MALTS) and a special needs college in Birmingham. Phil Odor explains: "It is becoming cheaper and easier to supplement teaching... view more... (2000-01-20)
This idea doesn't stink: New tech cuts industrial odors, pollutants
A North Carolina State University researcher has devised a new technology that really does not stink. In fact, it could be the key to eliminating foul odors and air pollutants emitted by industrial chicken rendering facilities and - ultimately - large-scale swine feedlots. view more (2009-08-27)
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)
Tracking down the human 'odorprint'
Each of the 6.7 billion people on Earth has a signature body odor - the chemical counterpart to fingerprints - and scientists are tracking down those odiferous arches, loops, and whorls in the "human odorprint" for purposes ranging from disease diagnosis to crime prevention. view more (2009-10-15)
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)
Gene determines whether male body odor smells pleasant
To many, urine smells like urine and vanilla smells like vanilla. But androstenone, a derivative of testosterone that is a potent ingredient in male body odor, can smell like either - depending on your genes. view more (2007-09-17)
Odd protein interaction guides development of olfactory system
Scientists have discovered a strange mechanism for the development of the fruit fly antennal lobe, an intricate structure that converts the chaotic stew of odors in the environment into discrete signals in the brain. view more (2007-10-30)
