What caused the loss of the Kursk remained unclear. Russian officials fell back on old Soviet habits of secrecy and confusion during the first days of the disaster. They made no announcement for two days, then issued a bland statement that there had been a "technical fault" and the boat was on the sea bottom. After the seriousness of the accident became clearer, Defense Minister Igor Sergeyev declared that there was "incontrovertible evidence" that the sub had collided with another vessel. In past years Soviet and U.S. vessels have had near collisions while spying on each other, but the Pentagon...
...Lower tire inflation gives a better grip on the road, a softer ride and, yes, a touch more stability, but it's also hell on tires. It's unclear whether that contributed to the blowouts responsible for 62 deaths, although at least one lawsuit now says it did. (Ford was also putting Goodyear tires on its Explorers then, and they apparently have fared fine.) Adding to the problems: It stands to reason that a more stable SUV would have handled those blowouts better, and saved some lives in the process...
Like vitamin A, vitamin E is found in several forms, with alpha-tocopherol being the most biologically active. Because alpha-tocopherol isn't terribly stable, however, most cosmeceuticals contain derivatives. Although some of these compounds are converted to the active form in the skin, it's unclear whether they have an effect. Even if you find a cream with alpha-tocopherol in it, there's no definitive word on how strong it should be, according to Dr. Karen Burke, a dermatologist who consults for L'Oreal's Helena Rubinstein division. However, Burke's experiments with mice suggest that vitamin...
...John Williams - longtime composer for George Lucas and noted Democrat Steven Spielberg - was represented by his ever-popular "Star Wars Theme," though it was unclear if it had been selected for its subtle call to arms for the impending battle against the evil empire of liberalism or because it was perceived to be a campaign tune promoting the SDI program...
...help her mom get elected to the Senate. Chelsea--the most potent familial ornament in American politics since Jackie Kennedy--has proved to be a campaign crowd pleaser, though whether she will do any stumping of her own or merely accompany her mother on the New York trail is unclear. While sending Mom back to Washington is a top priority, Chelsea also hopes to spend some quality time with Dad, to "experience and enjoy the final months of her father's presidency." Dropouts beware: this excuse is nontransferable...
