...pundits and editorial writers of Dr. Jack Kevorkian, who provokes strong feelings by shattering the taboo against physician-assisted suicide. The technical challenge involved in ending a human life is trivial, however. Cloning is another matter. Ian Wilmut, the embryologist who produced Dolly, the first clone of an adult mammal, says there are "serious safety issues" involved in cloning a human. In his experiments with animals, a quarter of his lambs died within a few days of birth. Ultimately, it took 277 attempts to produce Dolly. "Should we really consider or allow experiments of this kind with people?" Wilmut asks...
...these beasts are teaching aids, the best kind of illustrations for an expert on mammal anatomy. They are also convenient subjects to satisfy Crompton's curiosity about animals which began a long way from Cambridge...
...seaport, the rest of the country (and the rest of the world) must be completely in the dark. Fish, being slimy and all that, are not easy to get comfortable with, but if what happened to a noble creature like the swordfish was the fate of a land-based mammal of equal esteem, it would be headline news and somebody would be in jail. Thanks for dragging the news out of the depths. BILL AKIN Montauk...
...triplets are clones. The same technique has already been used with sheep, cattle, rabbits, pigs and even humans--although in the last case the embryonic clones were destroyed. What makes Dolly special is that she was cloned from an adult sheep, not from an embryo. She is the only mammal ever born that is identical to her biological mother...
PHILIP ELMER-DEWITT, TIME's science editor, knows firsthand how quickly technology can race ahead of those who think or write about it. While putting together the package of stories for this week's special report on the first cloning of an adult mammal, he was reminded that just four years ago, in another TIME cover story--one he wrote--we said the possibility of replicating an animal from the dna of fully developed cells is "far beyond the reach of today's science." The next technological step, he notes, might not be too far off. "Suddenly the possibility...
