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)
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)
‘Perfume’ lures flies into trap As part of a project funded by the NWO’s Technology Foundation (STW), a Groningen research team has investigated how flies react to the odours of such things as old pork, bread and chicken manure. The findings will be used to develop more effective flytraps, for example for use in stables. Flies are attracted to decaying and fermenting... view more... (2001-05-30)
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)
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. view more (2006-01-10)
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)
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)
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)
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)
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)
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 experience during critical period alters brain Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement. view more (2007-12-06)
New study examines how sense of smell affects mating and aggression in mice New research by scientists at UCSF sheds light on how the odor detecting system in mice sends signals that affect their social behavior. view more (2005-12-22)
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)
Mice use specialized neurons to detect carbon dioxide in the air For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby. view more (2007-08-17)
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)
Nose-on-a-chip Aims To Mimic The Real Thing An ambitious project is underway to build the world's smallest electronic nose. If the project succeeds, it is expected that the technology would have many potential applications in areas such as environmental monitoring, healthcare and food safety. The aim is to combine the odour sensors together with the signal processing components on to a... view more... (2002-03-04)
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)
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)
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)
