A major setback for "science" (as opposed to religious fanaticism, which is what supporting any other approach would be). In TCS:

The global grandees of therapeutic cloning recently gathered in sun-soaked Cairns, the gateway to Australia's Great Barrier Reef, for their annual conference.... But hovering over the buzz of morning coffee has been a dark cloud: as governments everywhere promote it, is therapeutic cloning going to be mothballed before it has produced a single cure?

Only a few days ago an article in the leading journal Nature brought amazing news. A Japanese team at Kyoto University has discovered how to reprogram skin cells so that they "dedifferentiate" into the equivalent of an embryonic stem cell. From this they can be morphed, theoretically, into any cell in the body, a property called pluripotency. It could be the Holy Grail of stem cell science: a technique that is both feasible and unambiguously ethical.

Gosh that sucks.

Well, one can always ignore it:

.... At the moment, the stem cell grandees, like all establishment figures, have no plans to change their tune. One of the stars of the Cairns conference, MIT's Rudolph Jaenisch, told Nature that therapeutic cloning remains "absolutely necessary."

Or attempt to make sure it doesn't reach sick people:

Executives from embryonic stem cell companies were not optimistic about the new technique either. Because it involves tinkering with the genome, it could be dangerous, warned Thomas B. Okarma, of Geron, the leading private company in the field. Getting approval from regulatory authorities would therefore become far more complicated.

"Nice medical breakthrough you got there! It'd be a real shame if something happened to it. Inn't that right, Luigi? Cos things break, don't they?"

What else could he say? No doubt manufacturers of vacuum tubes muttered about serious flaws in semiconductors when they first appeared on the market.

No doubt. But they probably weren't already thinking of reasons to encourage the government to make it difficult to obtain transistors.
