...example, whether Alzheimer's kills nerve cells (neurons) and whether it does so from the inside out or outside in. Supporters of the first scenario believe abnormalities in a protein called tau cause neurons in the brain's memory centers to clutter themselves up with tangled filaments, bringing cellular metabolism to a standstill. Still others think the damage is dealt by an external agent: the so-called beta-amyloid protein that aggregates in the brain, forming fibrous plaques. These plaques in turn injure neighboring neurons, causing them...
...their fancy mustaches. The sound effects are volcanic: a slap stings like a bullwhip. Benazir goes mad, her daughter grows up to be a race-car driver, the policeman's daughter becomes a cop and helps track down Habibullah's brother (who spits out his evil threats on a cellular phone--suddenly we're in today's India), and everything climaxes in an Armageddon of gunplay. With music...
...middle of northern Illinois dairy country, and about 50 miles northwest of Chicago, Harvard is a typical Midwestern farm town. Most of the 5,975 residents work on dairy farms, in tool and plastics manufacturing, or in health care. In June, Motorola Inc., the telecommunications giant, completed a cellular-phone facility, and is the town's largest employer. About 15 percent of the population is Hispanic...
...next solar maximum, due sometime around the year 2000, could create worse nightmares. For one thing, modern societies, with their cellular phones and satellite navigation and communications systems, have become more vulnerable than ever to electronic disruptions. Equally worrisome is the fact that electrical utilities have created enormous, interconnected power grids in an attempt to save money. The power outages that plagued the American West this summer provide a dramatic illustration of how vulnerable these systems have become. "The scale," says transmission expert John Kappenman of Minnesota Power and Light, "is scary." Financial losses alone would amount to billions...
...Karolinska team members, led by Henrich Cheng, took special pains to avoid the pitfalls that had tripped up investigators in the past. They widened the gap (by removing a quarter inch of spine) to ensure that no nerve tissue remained to produce false-positive results. Then they built their cellular bridges according to a precise blueprint that carefully distinguished between the two kinds of nerve tissue in the spinal cord--white and gray matter. White matter contains the parts of nerves that are surrounded by a substance called myelin, which acts like insulation around an electric wire. Gray matter contains...
