Nose odors and mouth odors: The brain distinguishes
Researchers have presented the first clear evidence that olfaction is uniquely a "dual" sense, in that the brain perceives the same odorant molecule differently if it arrives through the nose rather than the mouth. In the August 18, 2005, issue of , researchers report that the smell of chocolate activated different brain regions according to whether the odor was introduced into the o...Trio of plant genes prevent 'too many mouths'
A signaling pathway required for plants to grow to their normal size appears to have an unexpected dual purpose of keeping the plant from wallpapering itself with too many densely clustered stomata. "It's surprising that size and stomata patterning ?both key to plants being able to survive on dry land ?are using the same signaling components," says Jessica McAbee, a University of Washingto...Have a taste for fat? Yes! A sensor in the mouth promotes preference for fatty foods
The sense of taste informs the organism about the quality of ingested food. It comprises five sub-modalities that perceive sweet, salt, sour, bitter, and umami stimuli. The possibility for an additional taste modality directed to lipid has often been suggested because many animals exhibit a spontaneous attraction for fats, but the existence of an actual sensor remained a matter of debate. <...Dartmouth study finds that arsenic inhibits DNA repair
Dartmouth researchers, working with scientists at the University of Arizona and at the Department of Natural Resources in Sonora, Mexico, have published a study on the impact of arsenic exposure on DNA damage. They have determined that arsenic in drinking water is associated with a decrease in the body's ability to repair its DNA. "This work supports the idea that arsenic in drinking wate...GlycoFi and Dartmouth report full humanization of yeast glycosylation pathway in Science
For the first time, scientists have engineered yeast cells capable of producing a broad repertoire of recombinant therapeutic proteins with fully human sugar structures (glycosylation). These sugar structures ensure a glycoprotein's biological activity and half-life and to date, have necessitated the expression of therapeutic glycoproteins in mammalian hosts. The accomplishment reported today has...Pyrex brand low actinic narrow mouth Erlenmeyer flask, Pyrex ST 27 stopper from Sigma-Aldrich

While the foot and mouth disease is playing havoc with the economies ofdeveloped countries like the UK, India has been adopting a more conservativeapproach of vaccinating the animals for the past three decades. "Vaccinating the domestic animals against FMD on a regular basis is the bestmeans of preventing the spread of the disease," says Dr S M Lal, the jointdirector of the Banga...Acupuncture to bring relief to patients with dry mouth
