...expect Dr. Frankenstein to show up in wool sweater, baggy parka, soft British accent and the face of a bank clerk. But there in all banal benignity he was: Dr. Ian Wilmut, the first man to create fully formed life from adult body parts since Mary Shelley's mad scientist...
...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...
Following the local industrialist on the appointments list is the physics laureate. He is terminally ill. When he dies, one of the most remarkable minds in science will die with him. Reproductive chance might one day produce another scientist just as gifted, but there is no telling when. The physics laureate does not like that kind of uncertainty. He has come to the cloning lab today to see if he can't do something about...
...cyclical critter was due to hatch again anyway, but last week's revelation that Scottish scientists had succeeded in cloning a sheep amounted to a final whack at the snooze button. Now investors are wide awake to the potential wonders of biotechnology for the first time since a euphoric rally in those stocks in 1991. If you're a doctor or scientist, go ahead and take your best shot. Biotech certainly holds great promise, and you may well understand enough to pick the few stocks that will thrive. But overall the industry has been so consistently disappointing that laymen should...
...into a game's future to find a winning strategy. When your opponent is Kasparov, though, it's (thus far) impossible for even a 1.5-ton supercomputer to search far enough to be sure it chooses wisely. "Deep Blue sees everything in the searchlight very well," says research scientist Murray Campbell. "But after that, in the black beyond, it has to guess. And humans guess better...
