Cloning people? Depends on how you mean. An American biotechnology firm says it's successfully created the first cloned embryo of a human. The embryos they describe did not grow past the 4-cell or 6-cell stage, but if an embryo like this were to survive, and if it were placed in a womb and nurtured, there's a chance the first human clone could be born. The scientists insist vehemently that's not what they're after. They say they're in the business of therapeutic cloning, designing cells to cure disease and help people live longer. Critics say it's too much too fast, bad science, and that if this cloning isn't stopped now, or at least reviewed and regulated, the technology will be used to make people.
