Embryonic Stem Cells Obsolete? [SK]

I won't go so far as to say they will never work, but Nature has this to say about Induced Pluripotent Stem Cells (skin cells reprogrammed to function like ES cells):

The ten-year head start human ES cells got on human iPS cells has effectively shrunk to zero, says Thomson, because so much of the legacy of ES cells — reagents, culture media, hands-on expertise and experimental history — is transferable to iPS cells.

But as I've said before, don't expect the liberals in Congress to care one bit. They are determined to spend your money killing human embryos, no matter what science tells us.
