...seems to have anything bad to say about it -- but on the role of the U.S. in the post-cold war era. Even the Pentagon concedes that the Soviet Union is in such a state of internal disarray that it is unlikely to launch an offensive against the U.S. or any other NATO country. As for the rest of the world, Operation Desert Storm has just delivered an indelible lesson in the superiority of America's existing technology...
...National Cancer Institute is about to launch a study intended to resolve this debate, with results due in 2007. In the meantime, many doctors will have to decide for themselves. It seems clear that as the aging of the population puts more American men at risk, the pressure to use every possible tool, including PSA, will be hard to resist...
...voters will want to know what he is doing to save America. One early promise was to be "the education President," but his marks for that endeavor have been decidedly mixed. The President has apparently been doing his homework. Last week, striving to fulfill his promise to launch a major domestic initiative, he presented an ambitious national plan called "America 2000: An Education Strategy" to improve troubled U.S. elementary and secondary schools. Bush spoke of bringing about "a revolution in American education." The goal is lofty enough, but the President hopes to perform a miracle: he is offering relatively little...
Gamma rays are the most powerful type of radiation, thought to have been created during the explosion that launched the universe and its subsequent expansion. As distant heavenly bodies continue to collapse and explode, the only signals earth may receive of this activity are in the form of gamma rays. For example, gamma-ray bursters have been measured releasing more energy in a matter of seconds than the sun does in thousands of years. Since they carry no electric charge, gamma rays can plow through space unchanged, giving scientists a clear record of cosmic events. The atmosphere shields the earth...
...Better still, the atomic engines would be handy on a manned mission to Mars. Nonetheless, the program's political problems may be insurmountable. The 1979 accident at Three Mile Island shook America's confidence in nuclear technology, and the Challenger explosion dramatically demonstrated the vulnerability of space launches. Not surprisingly, many scientists are bothered by the idea of putting these two technologies together. In 1989, antinuclear activists, protesting potential "Chernobyls in the skies," organized the first civil-disobedience demonstrations aimed at halting a U.S. space shot. Their target: NASA's Galileo spacecraft, an interplanetary scientific mission that used...
