Everything about Shinya Yamanaka's discovery was right-except for the timing. The 44-year-old Kyoto University stem-cell researcher had found a way to genetically reprogram an ordinary mouse skin cell to revert to the virtual equivalent of its embryonic state, in which it has the potential to grow into any kind of tissue. The finding was a promising first step toward the creation of stem-cell lines for near-miraculous medical treatments-and because Yamanaka did not use human embryos, his technique offered researchers everywhere a way to sidestep the ethical controversies that have dogged the field...
...indeed possible to take a skin cell from an adult patient and tweak it to revert to an embryonic-type cell, that would mean that any patient needing a stem-cell-based treatment could, in theory, heal himself. Last year, Yamanaka was the first to announce success with this approach, by exposing the cells to four growth factors and nutrients. But the stem cells he generated were genetically abnormal and unstable. Building on the initial technique, Yamanaka's group, as well as those led by Rudolph Jaenisch at Whitehead and Konrad Hochedlinger at HSCI, showed that the process does indeed...
...what if he does? What if he could take who he is now, all that he's learned, and carry it back into the maelstrom? Could he stay as he is or would he revert? What if he launched a new kind of campaign: no handlers, just the liberated Gore talking about what really matters to him? Would he seem too squishy? These days he improvises, giving freer rein to matters of the heart and spirit than he ever could as a candidate. He draws from a number of faiths, from philosophy and self-help and poetry and from Gandhi...
...enrichment facilities on its own soil, but it is now being reported that Solana may offer a deal in which Iran would keep its current small-scale enrichment research facility, although not actually run it, for now. Reports suggest that the U.S. will push for the Natanz facility to revert to "cold standby," i.e. turning off but not dismantling the centrifuges, whereas Iran would counter that they be kept spinning, although empty of uranium...
Instead of having the TSA both regulate and operate airport security—a clear conflict of interest—we should leave the government to its proper oversight role and revert to the old system of private airport security provision. If the free market can protect Israel’s airports, where screeners are run by private companies, there’s no reason to believe it can’t guard American ones...
