...entirely attributed to genes, researchers calculated that heredity accounted for about 50% of the differences in activity. They also found that activity-promoting genes were dominant traits in 75% of the exercise-loving mice. (Researchers don't know yet how often the activity-inclined genotype would naturally occur; Lightfoot says he found a fairly continuous range of activity levels, from extremely active to very low-active, in about 30 mice strains he tested.) "When we used to talk about activity, it was whether or not people decided to be active," says Lightfoot. "Now it's clear that there...
...those of us who are not brain surgeons, driving is probably the most complex everyday thing we do," writes design journalist Vanderbilt in this look at the intricacies of the open road. Full of scads of cocktail-party factoids (half of all American road crashes occur at intersections; Saturday afternoons see more congestion than the typical rush hour), Traffic piles up fact after study after data point into an occasionally mind-numbing heap. Yet several of Vanderbilt's conclusions are eye-opening. Example: "We all think we are better drivers than we are." Propelled onto the road after a minimum...
...these changes, however, probably are not so harmful in healthy people. But for a person with a plaque in the coronary vessel, if these changes occur at the same time and peak at the same time, the final result is a higher risk of heart attack during that specific window of morning hours...
...decoys and debris. In half an hour, this lethal ''threat cloud'' would be over the U.S., raining destruction on cities and military targets alike. Trying to stop this deluge would require enormous technological breakthroughs in at least four areas: sensors, lasers, particle beams and computer programming. Should such advances occur, SDI proponents argue, a reasonably effective Star Wars defense would reduce to virtually zero the number of Soviet intercontinental ballistic missiles (ICBMs) getting through outer space to their targets. But critics respond that virtually zero is not enough when nuclear weapons are involved. Moreover, the Soviets have other ways...
...never explain. She refuses to elaborate on a mysterious religious conversion that took place % before her divorce from Lumet and led, presumably, to this book. And there are many occasions when the family chronicle becomes more like a family scrapbook in its sketchy and elliptical nature. But the omissions occur less because of carelessness than because emotional confession falls beyond the range of the Horne style. It may be that inside every black princess an empress of the blues is struggling to come out, shouting her salty grief like Bessie Smith. But like her mother, the author is too polite...
