...less about the magazine and more about the times (and the Times). As everyone now agrees, the 60s really began with the assassination of John F. Kennedy. The Vietnam protests, the ghetto uprisings, and of course sex, drugs and rock 'n roll cracked open, like a raptor from its egg. For the first years of that decade, we were, essentially, still in the 50s, with Doris Day reigning on the big screen and Father Knows Best on the small...
...process by which that is achieved is called nuclear transfer. The first step is to remove the nucleus from an egg and replace it with the nucleus of an adult cell (in Dolly's case, a cell from a ewe's udder). The two components are electrically fused and chemically activated to trick the hybrid cell into dividing like an embryo. Not surprisingly, the process doesn't always go right. "I call it a lottery," says Wilmut. "Even if you use the same method as consistently as you can, you may get some clones with severe abnormalities and some that...
...good news, as far as cloning's future is concerned, is that those problems seem to be limited to the clones and are not passed on to the next generation. When clones mate with ordinary animals, their offspring are created by the natural merging of egg and sperm--not by the reprogramming of a mature cell--which may erase any reprogramming errors in the clone. The proof is that Dolly gave birth to five healthy lambs. Cloned cows, pigs and mice are also bearing normal offspring. But when clones mate with other clones, all bets are off. Mice created this...
...egg donors? That was the question facing a task force of experts from the International Society of Stem Cell Researchers (ISSCR), who have spent the last six months trying to come up with a set of guidelines to regulate what's currently the wild west field of human embryonic stem cell research. They were in part motivated by the misconduct of South Korean stem cell researcher Woo Suk Hwang, who admitted earlier this year to paying women to donate eggs for study, a practice that many scientists believe is unethical because it could lead to coercion...
...tough New York City cop, Francis X. Loughlin has a knack for getting bad guys to give it up in front of the one-way mirror. Julian Vega was 17 and "as fragile as an egg in a carton" when Loughlin nailed him for the claw-hammer murder of a young doctor. Twenty years later, Julian, now prison hardened, has been freed on a technicality and is bent on proving he didn't do it. Loughlin is equally convinced he got the right guy, but his eyesight is failing from degenerative tunnel vision, and the case has taken a bizarre...
