Impaired ability to detect odors and irritants 2 years after buildings' collapse New research from the Monell Center and collaborating institutions reports that workers exposed to the complex mixture of toxic airborne chemicals following the 9/11 disaster had a decreased ability to detect odors and irritants two years after the exposure. "The nose performs many sensory functions that are critical for human health and safety," said lead author Pamela Dalton, PhD, MPH, an environmental...

Individual differences in liking for sweetness based in part on underlying biology New research from the Monell Center reports that children's response to intense sweet taste is related to both a family history of alcoholism and the child's own self-reports of depression. The findings illustrate how liking for sweets differs among children based on underlying familial and biological factors. "We know that sweet taste is rewarding to all kids and makes them feel good," said study lead author...

Endocannabinoid modulation of tongue sweet taste receptors may help control feeding behavior New findings from the Monell Center and Kyushu University in Japan report that endocannabinoids act directly on taste receptors on the tongue to enhance sweet taste. "Our taste cells may be more involved in regulating our appetites than we had previously known," said study author Robert Margolskee, M.D., Ph.D., a Monell molecular biologist. "Better understanding of the driving forces for eating and...

Natural compound in extra-virgin olive oil targets toxic beta-amyloid proteins Oleocanthal, a naturally-occurring compound found in extra-virgin olive oil, alters the structure of neurotoxic proteins believed to contribute to the debilitating effects of Alzheimer's disease. This structural change impedes the proteins' ability to damage brain nerve cells. "The findings may help identify effective preventative measures and lead to improved therapeutics in the fight against Alzheimer's disease,"...

NEW YORK, July 30 /PRNewswire-USNewswire/ -- Human pheromones are over-stated, or are they? There has been an on-going debate in the scientific community as to whether or not human pheromones exist, and, if they do, exactly what effect they have on us. For most of us in the lay community, pheromones are thought of as sexual attractants and nothing more. So the Sense of Smell Institute, the research and education division of The Fragrance Foundation, turned to the experts in the field and...

The New York City health department is urging parents to beware of illegal teething products and other illegal health remedies. Nancy Clark, assistant commissioner for the health department's environmental disease prevention bureau, said the warning is in response to a reported case of potassium bromide poisoning in an infant, associated with the use of a locally purchased teething product called Monell's Teething Cordial or Cordial de Monell para la Denticion. Potassium bromide is a potent...

Using a combination of sensory, genetic, and in vitro approaches, researchers from the Monell Center confirm that the T1R1-T1R3 taste receptor plays a role in human umami (amino acid) taste.They further report that variations in the genes that code for this receptor correspond to individual variation in sensitivity to and perceived intensity of umami taste."These findings bolster our understanding of human taste variation and individual differences in tastes for essential nutrients," says...

U.S. scientists say they've determined the red panda is the first non-primate mammal to display a liking for the artificial sweetener aspartame. Monell Chemical Senses Center researchers in Philadelphia said the unexpected affinity for an artificial sweetener might reflect structural variation in the red panda's sweet-taste receptor and the findings might shed light on how taste preferences and diet choice are shaped by molecular differences in taste receptors. Greater insight into why we...

Preference for artificial sweeteners previously thought to exist only in Old World primates Researchers from the Monell Center report that the red panda is the first non-primate mammal to display a liking for the artificial sweetener aspartame. This unexpected affinity for an artificial sweetener may reflect structural variation in the red panda's sweet taste receptor. The findings may shed light on how taste preferences and diet choice are shaped by molecular differences in taste receptors....

It is a lot more difficult to mask underarm odor from women's noses than men's noses, U.S. researchers said. The study, published online in the Flavour and Fragrance Journal, found underarm odors sniffed alone smelled equally strong to men and women. But while only two of 32 scents successfully blocked underarm odor from women's noses, 19 fragrances reduced the strength of underarm odor for men. Lead author Charles J. Wysocki at the Monell Chemical Senses Center, an independent non-profit...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
