The archive is a wonderful place for students to do some fast research. The archive's Student Center makes searching especially quick by offering a list of frequently researched topics, along with the best TIME articles on each subject. So, you have to write a 20-page term paper on...
Most of the scientists who gathered in Washington earlier this month to talk about human cloning agreed that cloning an entire human being--besides being morally questionable--was fraught with technical obstacles. After all, research into animal cloning has already shown that for every apparent success like Dolly the sheep...
Now comes word that it might be easier to clone humans than was previously believed. According to research at Duke University, people have a genetic quirk that might prevent some of the developmental deformities associated with animal cloning. "That doesn't mean there aren't other things that could go...
During cloning, however, most of these imprints are wiped out and have to be reset--that is, turned on or off. Chances are that some won't be reset properly, which could lead to severe birth defects.
What the Duke researchers showed is that one gene, called IGF2R, which helps brake growth, is normally imprinted in sheep, cows and mice but not in humans. Human clones would always inherit nonimprinted IGF2R genes, so there would be no chance of a mix-up and, at least in this...
