...United Nations to try Pol Pot for the deaths of some 2 million Cambodians, the measure must first gain the approval of the Security Council. That could prove tricky since China, a strong supporter of the Khmer Rouge regime, could easily block the trial by wielding its veto power. Trickier still: confirming that Pol Pot has actually been captured by rebel Khmer Rouge soldiers. The latest sighting, reported by a top Cambodian military official this weekend at Khmer Rouge headquarters, is difficult to take any more seriously than the contradictory reports of the past two weeks...
...trickier question--one that shows the Chivas Regal effect hasn't quite burned off--to pose to a university executive is, If you could cut tuition without sacrificing anything, would...
Scientists who have focused their cloning efforts on more forgiving embryonic tissue have met with greater success. A simple approach, called embryo twinning (literally splitting embryos in half), is commonly practiced in the cattle industry. Coaxing surrogate cells to accept foreign DNA is a bit trickier. In 1952 researchers in Pennsylvania successfully cloned a live frog from an embryonic cell. Three decades later, researchers were learning to do the same with such mammals as sheep and calves. "What's new," observes University of Wisconsin animal scientist Neal First, "is not cloning mammals. It's cloning mammals from cells that...
Software is a trickier problem. Although IBM annually sells $12.6 billion worth of code, twice as much as Microsoft, it isn't seen as much of a software innovator, something that's considered essential in the age of the Internet. Gerstner tried to repair that view with his $2.9 billion purchase of Lotus last year, but skepticism remains. "They're not really innovating on the Internet," says Jon Oltsik, an analyst at Forrester Research. "They're being outmaneuvered by Netscape and Microsoft...
...next step--letting computer systems actually pilot the car--is the big one. Getting in and out of the fast lanes is always tricky even today. It will be even trickier when you have to change lanes and hand off control to the computer at the same time. Making the transition to true no-hands smart roads, says David Cole, director of the University of Michigan's Office for the Study of Automotive Transportation, is an engineering challenge that will probably take another 20 years to complete. Even then the fledgling industry will face the daunting task of merging these...
