New successes in using DNA from fetal cells to clone transgenic animals
have boosted a new biotech business, but low success rates still need to
be improved

Births are usually announced on a newspaper's society or personal pages, not on the front page. But that convention didn't apply to Dolly and Polly and--just last week--George and Charlie. These white-faced lambs and Holstein calves made headlines as the products of cloning technologies that have generated fascination and fear--a reaction fanned this month by the improbable claims of a physicist who says he plans to clone adult humans within 2 years (Science, 16 January, p. 315). But the technologies have done more than spawn an ethical debate about the prospects for human cloning: They have also
galvanized efforts to create transgenic livestock that will act as living factories, producing pharmaceutical products in their milk for treating human diseases and, perhaps, organs for transplantation.
Cash calves. These calves prove that nuclear
transfer can lead to transgenic cattle.
