Scientists working in a laboratory at Vanderbilt University have potentially discovered a class of insect repellent that is 1000 times more effective than DEET and works against all types of insects. "It wasn't something we set out to find," said David Rinker, a graduate student who performed the study in collaboration with graduate student Gregory Pask and post-doctoral fellow Patrick Jones. "It was an anomaly that we noticed in our tests." Reported in the online edition of the Proceedings...

Scientists assemble genes involved in regulating olfaction in the antennae of a moth Insects have a highly sensitive sense of smell. Extremely low concentrations of odor molecules in the air are sufficient to be detected by receptor neurons on their antennae. Specific proteins, so-called receptor proteins, expressed in these neurons recognize the odors. The odor molecules bind to the receptors and produce chemical and electrical signals that are processed in the insect brain and eventually...

Mice know fear. And they know to fear the scent of a predator. But how do their brains quickly figure out with a sniff that a cat is nearby? It's a complex process that starts with the scent being picked up by specific receptors in their noses. But until now it wasn't clear exactly how these scent signals proceeded from nose to noggin for neural processing. In a study to be published in Nature (available online now to subscribers), Stanford researchers describe a new technique that makes it...

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...

'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...

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...

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...

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....


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
