It depends on who you ask. Earlier this week, researchers announced that they’d successfully turned adult skin cells into embryonic stem cells. Headlines were made — including more than one that heralded this as the first step in human cloning. If you believe The New York Times, The Los Angeles Times, and Fox News, this research was a big deal. The Boston Globe and The Washington Post, however, had a different take. According to those sources, this is more of a technical advance (but not one that counts as a “breakthrough”) and something that’s unlikely to have any clinical relevance whatsoever.
