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)
Studies assess effectiveness of serotonin and nerve stimulants on irritable bowel syndromes
Studies have shown that gastrointestinal (GI) tract function is often influenced by specific stimulants or reactors, which sometimes cause irritable bowel syndrome (IBS) or constipation. view more (2007-05-22)
Left-right wiring determined by neural communication in the embryonic worm
Most animals appear symmetrical at first glance, but we're full of internal lop-sidedness. From the hand used to pick up a pencil or throw a baseball, to where language is generated in the brain, to the orientation of our internal organs, humans are a glut of asymmetries. view more (2007-05-18)
Biosensor sniffs out explosives
Temple University School of Medicine researchers have developed a new biosensor that sniffs out explosives and could one day be used to detect landmines and deadly agents, such as sarin gas, according to a paper in the June issue of Nature Chemical Biology. view more (2007-05-09)
The brain is more adept at using the nose than previously realized
Brains are able to adjust automatically to the demands of distinguishing between small differences in smell, new research at the University of Chicago shows. view more (2007-04-30)
When smell cells fail they call in stem cell reserves
Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. view more (2007-04-30)
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)
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. view more (2007-03-14)
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)
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)
Biologists find biological clock for smell in mice
Biologists at Washington University in St. Louis have discovered a large biological clock in the smelling center of mice brains and have revealed that the sense of smell for mice is stronger at night, peaking in evening hours and waning during day light hours. view more (2006-12-19)
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)
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)
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)
Alcoholics' deficits in smell are linked to frontal lobe dysfunction
Prior research has shown that chronic alcoholism is associated with numerous olfactory deficits in odor judgment, odor identification, odor sensitivity, and the ability to qualitatively discriminate between odors. New findings indicate that olfactory deficits among alcoholics are associated with prefrontal cognitive dysfunction, specifically,... view more... (2006-07-25)
Smell of success for nanobiosensors
Modern-day doctors may soon start using smell to detect the early warning signs of different illnesses thanks to technology that replicates-and improves upon-the human olfactory system thanks to tiny bioelectronic sensors. view more (2006-05-15)
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)
One gene provides fruit fly both antenna and color vision
A team of researchers that includes biologists from Washington University in St. Louis has discovered that a gene involved in the development and function of the fruit fly antenna also gives the organism its color vision. view more (2006-04-05)
MNI researchers find that sense of smell is dependent on body position
Before giving flowers or scattering rose petals on Valentine's Day, make sure your significant other has already gotten out of bed. view more (2006-02-03)
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)
