...findings, published in the current issue of the journal Cell, suggest that the sense of smell may work very differently. When odor molecules drift among the millions of tiny cilia located high in the nasal cavity, they seem to slip into certain odor receptors like keys into locks. The fact that there are such a large number of different kinds of odor receptors suggests that much of the work of discriminating among smells is being carried out at a chemical level within the nose itself. Signals from these receptors are then transmitted to the olfactory bulb, the small region...
...nose, therefore, may be a key to understanding how the brain works. "These molecules will serve as useful tools" for solving a variety of scientific problems, says Linda Buck, who co-authored the Cell article with Axel. This knowledge may even yield some practical benefits. Pesticide makers may be able to design improved insect repellents based on a better understanding of why certain pests are attracted to some people and not to others. And who knows, perfume manufacturers could someday offer custom-made scents that are designed to snare not just any man, but a particular, special someone...
Madras explained that when nerve cells communicate, one nerve ending secretes a chemical, which sets off a sequence of events in an adjacent cell. This sequence must be stopped, Madras said, or the action coded by the sequence will continue indefinitely...
When Colombian police began cracking down on the narcotics trade, traffickers coined a defiant slogan: "Better a tomb in Colombia than a cell in the United States." Now that drug kingpins can avoid extradition under a new plea- bargaining agreement, a cell in Colombia has become a very attractive compromise. Since Medellin drug-cartel leaders Jorge, Fabio and Juan David Ochoa surrendered to Colombian authorities in recent months, they have been housed in a custom-tailored facility. Angry U.S. drug-enforcement officials complain that the Ochoa brothers are enjoying posh accommodations equipped with fancy furniture, stereos and cable television...
There were approximately 60 resistance groups operating at any given time, each with 40 to 50 members. The head of each cell knew his opposite number in other units, but his subordinates did not know one another. Elaborate codes were developed to fool eavesdropping Iraqis. Young girls carried bullets in their underwear. Fake identifications were common. A sophisticated printing operation was hidden a block from the headquarters of Iraq's secret police...
