Cloned ?

Imagine for a moment that your daughter needs a bone-marrow transplant and no one can provide a match; that your wife's early menopause has made her infertile; or that your five-year-old has drowned in a lake and your grief has made it impossible to get your mind around the fact that he is gone forever. Our two-year-old daughter died in a car crash; we saved a lock of her hair in a baby book. Can you clone her? Why does the law allow people more freedom to destroy fetuses than to create them? 

The inquiries are pouring in because some scientists are ever more willing to say yes, perhaps we can. A well-known infertility specialist, Panayiotis Zavos of the University of Kentucky, announced that he and Italian researcher Severino Antinori, the man who almost seven years ago helped a 62-year-old woman give birth using donor eggs, were forming a consortium to produce the first human clone. Researchers in South Korea claim they have already created a cloned human embryo, though they destroyed it rather than implanting it in a surrogate mother to develop.
When it finally happened -- after years of ethical hand wringing and science- fiction fantasy -- it was done in such a low-key way by researchers so quiet and self-effacing that the world nearly missed it. The landmark experiment was reported by Jerry Hall at a meeting of the American Fertility Society in Montreal.Also, The efforts of the Raelians, a religious group committed to, among other things, welcoming the first extraterrestrials when they appear.They intend to clone the cells of a dead 10-month-old boy whose devastated parents hope, in effect, to bring him back to life as a newborn. The Raelians say they have the lab and the scientists, and--most important, considering the amount of trial and error involved--they say they have 50 women lined up to act as surrogates to carry a cloned baby to term.


Given what researchers have learned since Dolly, no one thinks the mechanics of cloning are very hard: take a donor egg, suck out the nucleus, and hence the DNA, and fuse it with, say, a skin cell from the human being copied. Then, with the help of an electrical current, the reconstituted cell should begin growing into a genetic duplicate. It's inevitable that someone will try and someone will succeed," predicts Delores Lamb, an infertility expert at Baylor University. The consensus among biotechnology specialists is that within a few years--some scientists believe a few months--the news will break of the birth of the first human clone.
