...formidable enough opponent, mainly because researchers still don't understand the method to its madness. Like all viruses, HIV is simply a strand of genetic material (in this case the nucleic acid RNA) surrounded by a protein coat. A virus lacks the tools to reproduce unless it invades a living cell and takes over the host's molecular machinery. The intruder can then produce many copies of itself, eventually killing the cell. One of HIV's favorite targets is the CD4 T-cell, an important player in the human immune system...
...nonathletes dashing from the shower to grab a ringing phone -- rely to a large extent on this system, which provides lots of quick power but can operate for only a short time. The reasons: depletion of the necessary chemicals and buildup of a chemical by- product called lactic acid, which inhibits muscle contraction. Middle- distance athletes depend on a delicate balance of both aerobic and anaerobic systems...
...terms of transportation and use in various engines, including diesels and turbines, put it in direct competition with oil and gas. Coal's chief disadvantages are that it is bulky and dirty. Sulfur oxides (SOx) and nitrogen oxides (NOx) have been indicted as principal villains in the formation of acid rain. More than half the nation's electricity is produced by power plants that burn coal. By running finely ground coal through a chemical bath (currently pentane, a hydrocarbon similar to butane), the Otisca process separates out all but 1% of the mineral content...
...drawing up plans for a house renovation: "I walked in and was able to visualize all four levels of the structure at once -- where all the plumbing was, the electrical outlets -- without once referring to the blueprints." Another user recalls instantly becoming "witty and logical" after taking the amino acid pyroglutamate, while a third says that on Hydergine he suddenly could remember ordinary events that had occurred more than 20 years before...
Salesmen of smartness have embraced an impressive vocabulary to explain how the drugs work: one amino acid, said a pumped-up advocate, "inhibits an enzyme that breaks down the endorphins and enkephalins localized in the brain." Another "causes an increase in a particular neurotransmitter involved in mental alertness. Your arousal index is much higher...
