What magic is there in embryonic stem cells to make some scientists so economical with the truth and some science journals so credulous? Only a few months after the disgraceful Korean stem cell scandal, another scientist has again announced a breakthrough, and has again been denounced as a liar.
Last week a Massachusetts company declared that it had mastered a technique for creating “ethical” embryonic stem cells which could break the logjam in America’s stem cell politics. The world’s leading science journal, Nature, rushed the news into its on-line express edition. Since stem cells could become the key medical platform for the 21st century, finding a way to harvest the most versatile variety without destroying human embryos would have been a major coup. And this is the way Advanced Cell Technology described its work in a press release.
