A new study in the Journal of General Physiology (JGP) shows that the contribution of odorant receptors (ORs) to olfactory response in mammals is much more complex than previously thought, with important consequences for odorant encoding and information transfer about odorants to the brain. The study appears online on October 25 (www.jgp.org). ORs, which provide a system for mammals to discriminate between many different odors, form a large, diverse group of G protein"“coupled receptors...

NOXO Study Boostâ“ž¢ and NOXO Memory Enhancerâ“ž¢ are important, safe and effective alternatives for users of illegal and non prescribed amphetamines (Adderall). Beyond the serious the health and legal consequences of the Class II controlled drug is the ethical debate surrounding Adderall's devaluation of the college experience and the lack of knowledge of the drug's short and long-term effects including schizophrenia. Wynnewood, PA...

'Sister' mitral cells may broadcast 2 distinct channels of information on odors to the cortex A team co-led by neuroscientists at Cold Spring Harbor Laboratory (CSHL) has shed light -- literally -- on circuitry underlying the olfactory system in mammals, giving us a new view of how that system may pull off some of its most amazing feats. It has long been known from behavioral experiments that rodents, for instance, can tell the difference between two quite similar odors in a single sniff. But...

Harvard University neurobiologists have created mice that can "smell" light, providing a potent new tool that could help researchers better understand the neural basis of olfaction. The work, described this week in the journal Nature Neuroscience, has implications for the future study of smell and of complex perception systems that do not lend themselves to easy study with traditional methods. "It makes intuitive sense to use odors to study smell," says Venkatesh N. Murthy, professor of...

Solomon's lily imitates a yeasty odor to lure vinegar flies into a trap Scientists from the Max Planck Institute for Chemical Ecology in Jena, Germany, have solved a case of fraud that has been pending for 40 million years. Arum palaestinum, also called the Solomon's lily, attracts drosophilids (vinegar flies) as pollinators by emitting odor molecules that resemble those produced during alcoholic fermentation of rotting fruit initiated by yeast. The plant accomplishes the illusion of yeast...

Research published in the journal Genetics identifies pieces of control DNA that turn on or off genes that allow fruit flies to differentiate between smells, paving the way for better insect repellents By following the "nose" of fruit flies, Yale scientists are on the trail of new insect repellents that may reduce the spread of infectious disease and damage to agricultural crops. That's because they've learned for the first time how a group of genes used to differentiate smells is turned on...

BARRINGTON, Ill., Sept. 13 /PRNewswire/ -- The start of a new football season at Soldier Field has never smelled so sweet. OMI Industries, manufacturers of the Fresh Wave brand, announced today that they have signed on as a sponsor to the 2010-2011 Chicago Bears football season. Beginning with season kick-off on September 12, everything from the Chicago Bears' locker rooms to the suites at Soldier Field will be outfitted with the eco-friendly Fresh Wave odor eliminating solutions....

EMBL scientists uncover counterpart of cerebral cortex in marine worms Our cerebral cortex, or pallium, is a big part of what makes us human: art, literature and science would not exist had this most fascinating part of our brain not emerged in some less intelligent ancestor in prehistoric times. But when did this occur and what were these ancestors? Unexpectedly, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now discovered a true counterpart of...

By David F. Salisbury Origin of DEET's repellent effect confirmed It now appears that the malaria mosquito needs more than one family of odor sensors to sniff out its human prey. That is the implication of new research into the mosquito's sense of smell published in the Aug. 31 issue of the online, open-access journal Public Library of Science Biology. The experiments described in the paper provide striking new evidence that Anopheles gambiae "“ the species of mosquito that spreads...

Two new studies reveal that the commonly used insect repellents DEET and citronellal each work through a dual stimulation of insect sensory systems. The research findings, published by Cell Press on August 26 in the journals Neuron and Current Biology, enhance our understanding of how insects respond to repellents and may lead to the discovery of improved compounds for controlling insect-borne disease. Insect pests pose a major threat to humans across the world. In addition to spreading...

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...
