The scientist that helped clone Dolly the sheep has moved away from cloning and toward making embryonic-like stem cells without eggs. The shift is described in an article and interview in Scientific American. Wilmut (and others) think that iPS cells might one day replace ES cells for clinical applications and drug-testing applications, but no one thinks that day is now here. Bits of the SciAm articles are floating around the blogosphere, but these (willfully?) strip away some of the nuances, so it’s worth reading the full articles from the source. I also think that the article conflated and neglected a few ideas, which I’ll outline below.
