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)
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)
Blue tits love the smell of perfumed nests!
French birds love the smell of perfumed nests. In an article published this month in Ecology Letters, scientists from the Centre National de Recherche Scientifique report that a small cavity-nesting bird on the island of Corsica, the blue tit, adorns its nests with fragments of strongly perfumed plants, including lavender and mint. The chemical... view more... (2002-07-11)
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)
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)
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 research shows that the smell of smoke does not trigger relapse in quitters
Research into tobacco dependence published online today (Friday 17 October 2008) in the November issue of Addiction, has shown that recent ex-smokers who find exposure to other people's cigarette smoke pleasant are not any more likely to relapse than those who find it unpleasant. view more (2008-10-17)
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)
Study shows no change in sense of taste after tonsil removal
In a small study of patients undergoing tonsillectomy, or removal of the tonsils, none reported an ongoing dysfunction in their sense of taste following the procedure. view more (2007-07-17)
UIC researchers show protein routes messages in nerve cells
Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message? view more (2005-07-14)
‘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)
Scientists discover the gene that causes the smell of the earth and leads camels to water.
Scientists at the John Innes Centre (JIC), Norwich(1) have discovered the gene that gives freshly turned soil its distinctive smell. A smell, it is believed, that enables camels to find water in the desert. The ‘earthy’ smell is caused by geosmin(2), a chemical produced by a common bacterium, Streptomyces coelicolor(3), that is found... view more... (2003-02-05)
Duck-billed dinosaur crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected - the sense of smell. view more (2006-01-25)
Sweet smell
What makes one smell pleasant and another odious? Is there something in the chemistry of a substance that can serve to predict how we will perceive its smell? view more (2007-09-18)
Researchers find new taste in fruit flies: carbonated water
That fruit fly hovering over your kitchen counter may be attracted to more than the bananas that are going brown; it may also want a sip of your carbonated water. view more (2007-08-30)
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)
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)
Smokers see decline in ability to smell, rise in laryngitis, and upper airway issues
As Americans prepare for a day without cigarettes and tobacco products as part of the American Cancer Society Great American Smokeout (R) (November 20), new research gives them more reasons to extend that break to a lifetime. view more (2008-11-04)
Long-Lasting Perfume
Researchers of the Moscow State Textile University have invented the way to impart a stable fragrance to fabrics and polymeric fibers. The smell of rose, hyacinth or lily of the valley does not disappear even after washing. The application of aromatic rugs, polymeric fiber napkins or fragrant fabrics will be driven by fantasy that can be put to... view more... (2003-12-30)
Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. view more (2009-10-22)
