...revelation, first reported yesterday in The Boston Globe, comes two weeks after a South Korean laboratory became the first to extract a line of stem cells from a cloned human embryo, disappointing Harvard researchers who had been pursuing the achievement...
Technically speaking, the Hartman baby was a true hermaphrodite. Scientists don't know how this happens, but one possible explanation is that two eggs are fertilized in the womb--one XX and the other XY--but rather than developing separately into twins, the zygotes merge to become one embryo. At any rate, "hermaphrodite" is not one of the options available on a birth certificate, so the Hartmans' doctors struggled to figure out which sex was more appropriate for the child. Meanwhile, Debbie's sister and mother told relatives and friends not to send anything pink or blue. "They said yellow...
Once it was out, the news that human embryos had been cloned flew around the world with the speed of sound bites bouncing off satellites ... It was the start of the fiercest scientific debate about medical ethics since the birth of the first test-tube baby 15 years ago. A line had been crossed. A taboo broken. A Brave New World of cookie-cutter humans, baked and bred to order, seemed, if not just around the corner, then just over the horizon. Ethicists called up nightmare visions of baby farming, of clones cannibalized for spare parts. Policymakers pointed...
Last Thursday, South Korean scientists Dr. Woo Suk Huang and Dr. Shin Young Moon became the first to extract a line of stem cells from a cloned human embryo, clearing the first hurdle towards therapeutic cloning—a method aimed at treating diseases rather than making babies...
...Korea, and last December they announced the successful cloning of a cow resistant to mad-cow disease. But they were also looking at how cloning could benefit humans. Their team has cloned miniature pigs whose organs could potentially be used for transplant to humans. But cloning a human embryo was a faster route to growing replacement organs and tissue...
