Kudos to the author for pointing out the distinction between stem cells derived from the destruction of an embryo and stem cells derived from adult tissue, and for explaining which type of stem cells this research involves (embryonic). Too often, even reputable news sites don't properly explain the difference, or even say which of the two they're talking about.
