Researchers at UCLA and Hewlett-Packard have succeeded in constructing microscopic integrated circuits using single molecules as building blocks, an achievement that could lead the way to stunningly powerful and compact computers. Conventional computers are powered by tiny circuits etched in silicon by a laser, but a computer based on molecule-sized circuits would be vastly more compact and require much less power -- James Heath, the UCLA professor leading the project, has suggested that a molecular computer with the processing power of 100 conventional PCs would be about the size of a grain of salt...
...table hops and thumps like a flamenco dancer. I ask it, "How do you think Hillary Clinton will do against Giuliani? What about the presidency in 2004?" The table tells me Hillary is a great American story forming. I seem to hear the distant voice of Madonna singing the lead...
...credit, Bristol-Myers Squibb has also taken the lead in philanthropy, with an offer to give $100 million to fight AIDS in five African countries over the next five years. A sizable chunk is earmarked to bring African doctors to the U.S. so they can be trained to carry out research and clinical trials back in Africa. But even that has raised a red flag among activists. "A lot of the companies are using the cheaper labor costs and the lack of ethical codes in developing countries as a way to get the trials done more cheaply and quickly," says...
Global warming, tanker spills in Alaska, the Gulf War: the thread running through all these tragic events is America's dependence on oil. Will a former oilman from Texas, George W. Bush [CAMPAIGN 2000, June 21], lead America to a future of alternative fuels? Where does his allegiance lie? In all likelihood the presidential election in 2000 will be a showdown between Bush and Gore, and the emphasis placed on environmental policy will be a clear way to distinguish between the two candidates. Is the public informed and mature enough to understand the importance of moving away from fossil fuels...
...they would love to have such problems. When kids pour out of school each day in scores of lower-income urban communities, all that awaits them is the street--no soccer, baseball or ice skating. They just hang out, while their parents pray that dead-end afternoons won't lead to sex or drugs or violence. "Most teenage pregnancies happen between 2 and 5 in the afternoon," says Les Franklin, founder of the Shaka Franklin Foundation for Youth, a nonprofit group based in Denver that provides counseling and other services for urban youngsters. "In our neighborhoods, the concept of 'soccer...
