Two recently diverged populations of a southern California songbird produce unique odors, suggesting smell could contribute to the reproductive isolation that accompanies the origin of new bird species. The Indiana University Bloomington study of organic compounds present in the preen oils of Dark-eyed Juncos is described in this month's Behavioral Ecology. "There's so much we don't know about the role of smell in bird behavior," said biologist Danielle Whittaker, the study's lead author....

Desert ants perceive odor maps in stereo and use this information for navigation Scientists of the Max Planck Institute for Chemical Ecology in Jena have investigated another navigational skill of desert ants. These ants are already well-known for their remarkable visual orientation: they use a sun compass along with a step counter and visible landmarks to locate their nest after foraging for food. After the research team from Jena recently discovered that these ants also use olfactory cues...

Scientists at Vanderbilt and Yale universities have successfully transplanted most of the "nose" of the mosquito that spreads malaria into frog eggs and fruit flies and are employing these surrogates to combat the spread of the deadly and debilitating disease that afflicts 500 million people. The research is described in two complimentary papers, one published this week in the early online edition of the Proceedings of the National Academy of Sciences and the other which appeared online Feb....

Yale study may lead to better traps, repellents Yale University researchers have found more than two dozen scent receptors in malaria-transmitting mosquitoes that detect compounds in human sweat, a finding that may help scientists to develop new ways to combat a disease that kills 1 million people annually. These olfactory receptors in the mosquito Anopheles gambiae offer scientists potential new targets for repelling, confusing or attracting into traps the mosquitoes that spread a disease...

Olfactory dysfunction in mouse model may correlate to humans A study published in the January 13, 2010 issue of the Journal of Neuroscience links a loss of smell function in Alzheimer's disease (AD) model animals with amyloid  (protein) accumulation in the brain, a distinguishing hallmark of Alzheimer's disease. Research conducted by NYU Langone Medical Center suggests that olfactory dysfunction, a common symptom of AD, may serve as an early diagnostic tool...

NEW YORK, Jan. 5 /PRNewswire/ -- Nalls Studio announces the release of olfactory inkblot_1, the first in the new olfactory inkblot series by artist Gayil Nalls. The olfactory inkblots are limited edition multiples, a series of interactive experiential works that asks the user to explore olfactory perception and their psychophysical response to natural smells. olfactory inkblot_1 is staged in the everyday object of a candle. As an interactive artwork, participants are asked to engage with...

As anyone suffering through a head cold knows, food tastes wrong when the nose is clogged, an experience that leads many to conclude that the sense of taste operates normally only when the olfactory system is also in good working order. Evidence that the taste system influences olfactory perception, however, has been vanishingly rare"”until now. In a novel study this week in Nature Neuroscience, Brandeis researchers report just such an influence. Neuroscientist Don Katz and colleagues...

The use of an electronic smelling system capable of discriminating which tomatoes, melons or other products have a more attractive aroma is a particularly valuable aid for agro-food firms. However, existing electronic noses do not "smell" in the same way depending on the laboratory conditions, and these conditions change throughout the day and from one day to another. In order to overcome these fluctuations, researchers from the Agro-Food Quality Improvement Group at the Universitat Jaume I...

The nose is the organ that extends outward in the middle of the face between the eyes and mouth. Formation and Orientation The shape and look of the nose is dependent on the ethmoid bone and the nasal septum which is the cartilage that separates the two nostrils. The evolutionary hypotheses of nose development in humans propose that noses are alterations of the angles of the skull because of bipedalism. Because of the change in diet that has come with modern time and the change of...
