Stem Cell Research Breakthrough

Scientists are hailing it as a jaw-dropping discovery. It's a way to make stem cells without destroying human embryos and it can be put into practice today.

Researchers have figured out how to transform ordinary human skin cells into batches that look and act like embryonic stem cells.

The breakthrough could make possible the long-sought goal of tailor-made medicine, but without the political and ethical dilemmas of using human eggs or embryos.
