Physicists Solve Longstanding Puzzle Of How Moths Find Distant Mates

Provided by Kim McDonald, UC San Diego The way in which male moths locate females flying hundreds of meters away has long been a mystery to scientists. Researchers know the moths use pheromones to locate their mates. Yet when these chemical...

April Flowers for redOrbit.com - Your Universe Online The older generation is a source of constant study for scientists seeking to understand why some of us live such long lives, and some of us die relatively early. Studies have found many predictors of death in the elderly, including broken hips, love handles and nocturia (frequent bedwetting). A new study from the University of Chicago has added loss of smell (olfaction) to that list. The findings, published in PLOS ONE, reveal that...

Clothes Made Of Polyester Smell Worse Than Cotton After Exercise
2014-09-04 03:03:12

American Society for Microbiology Polyester clothes smell worse than cotton, following intensive exercise by their wearers, because bacteria that cause odor grow better on polyester, according to research published ahead of print in the journal Applied and Environmental Microbiology. In the study, the investigators collected t-shirts from 26 healthy individuals following an intensive, hour-long bicycle spinning session, and incubated the shirts for 28 hours before having them inspected...

University City Science Center and Monell Chemical Senses Center Partner to Bring Scent-based Installation to Esther Klein Gallery Philadelphia, PA (PRWEB) August 26, 2014 The human nose can detect a trillion different odors, some of which will be featured at A Big Stick of Confidence, a scent-based installation by Canadian artist Clara Ursitti at the University City Science Center’s Esther Klein Gallery at 3600 Market Street in Philadelphia. The exhibit, which is jointly presented by...

The Institute for Preventive Foot Health combed the literature to see what strategies might be backed by science. Statesville, NC (PRWEB) August 05, 2014 Smelly feet, technically known as “bromhidrosis,” are a fact of life, especially in warmer weather. Simply washing and drying your feet, while helpful, won’t necessarily take care of the problem. That’s because foot odor is caused by bacteria that breed in wet or moist environments on and around the feet; once your feet start to...

Harvard University Study shows that mice can identify specific odors amid complex olfactory environments For many animals, making sense of the clutter of sensory stimuli is often a matter or literal life or death. Exactly how animals separate objects of interest, such as food sources or the scent of predators, from background information, however, remains largely unknown. Even the extent to which animals can make such distinctions, and how differences between scents might affect the...

- New-to-the-World Technology Rids Odors Completely, Ensuring the Best Guest Experience - DAVIE, Fla., July 29, 2014 /PRNewswire/ -- Among the most challenging issues hoteliers face is keeping guest rooms smelling truly fresh and clean. Most products on the market today temporarily treat the air, masking unpleasant smells with air fresheners and deodorizers or using machines that claim to clean the air. Just a few hours after application, the odor returns -- followed quickly by guest...

Cold Spring Harbor Laboratory Sense of smell is critical for survival in many mammals. The ability to distinguish different odors, which is important for sniffing out food, avoiding predators, and finding mates, depends on the number and type olfactory receptors found in an organism's genome. In a study published this week in Genome Research, researchers examined the olfactory receptor (OR) repertoire encoded in 13 mammalian species and found that African elephants have the largest number...

Fumairx permanently eliminates offensive odors molecularly using a blend of non-toxic natural ingredients so no nose will ever know there was ever a stench. Rock Hill, SC (PRWEB) July 08, 2014 Buying a home, selling a car or using a public bathroom - smell matters. It turns out sense of smell is basic but its warnings can be lethal whether its smoke, bad meat or polluted water smell influences all our buying decisions. In fact, surveys on reactions to odors show olfactory likes and...

Sandra Hines, University of Washington Car and truck exhaust fumes that foul the air for humans also cause problems for pollinators. In new research on how pollinators find flowers when background odors are strong, University of Washington and University of Arizona researchers have found that both natural plant odors and human sources of pollution can conceal the scent of sought-after flowers. When the calories from one feeding of a flower gets you only 15 minutes of flight, as is...

Alan McStravick for redOrbit.com - Your Universe Online The sense of smell in humans has undergone many permutations as we have traveled through evolutionary time. It was once believed that each successive version of our olfactory ability was weaker than the last. Scientists claimed as our sense of sight became ever greater and required more of our energy, our sense of smell suffered. They cited the gradual reduction of our noses paired with the movement of our eyes closer to the middle of...

Nose
2013-03-05 14:47:26

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...
