This video segment adapted from NOVA scienceNOW tells the story behind one of the most significant scientific breakthroughs in the past decade. Human embryonic stem cells, once thought to be the key to curing countless debilitating diseases, have sparked a decade-long firestorm of ethical and political debate in the United States that has greatly curtailed their use in scientific research and medical therapies. Now a revolutionary method of creating stem cells—without embryos—may pave the way to swifter progress in the effort to understand and cure diseases.
