...that are still capable of dividing - like the mammary cell that created Dolly and the skin cell that became Snuppy - they used blood cells near the end of their life cycles that could no longer divide. It was these older, mature cells that produced more cloned embryos than the younger ones. "To our surprise, the fully differentiated cells were more efficient in producing cloned embryos," says Yang, a director of the University's Center for Regenerative Biology...
...fact, Yang's findings fly in the face of conventional wisdom in the cloning field, which held that cloning, which involves turning back the clock on adult cells, worked better with younger, more "embryo"-like cells. The less that the cloning process has to undo, the theory goes, the more successful the technique will be. In fact, there was good evidence to support this theory: In previous studies embryonic stem cells, which can generate all of the body's cell types, produced clones ten times more efficiently than adult stem cells, which can develop into only a restricted number...
...mind. Even if Europe doesn't have the heft it used to, the U.S. will find managing the rise of Asia's new powers much harder without help from the bulk of the most prosperous democracies. Even if the U.S. seems more and more like another planet to younger Europeans, the problems posed by Islamic radicalism and Iranian nuclear weapons, to say nothing of global warming, will fester if the U.S. is not involved in seeking solutions. So how could Europeans be persuaded to stop turning away from the U.S. and engage again? A first step would...
...resignation, they predict, will resonate well beyond Florida - and could have a downer effect on young people contemplating careers in politics. "With boomers retiring, we need the new generation to come into politics," says MacManus. "But this is the kind of episode that has a chilling effect especially on younger folks because they identify most with the kinds of things involved - the Internet, the power of bloggers and such." In other words, today's brand of personal politics may, as the congressional page might put it, end up freaking them...
...fierce in questioning authority. Hillary - and so many people in the Senate - did not look at the grounds for the war in Iraq in an effective or thorough way. As a matter of fact, she supported it. I can't get behind that. Right now I'm looking for younger women at the grassroots level who I can help develop and support as they become leaders, people who are coming from a place where they're fighting for justice, peace and equality, not for political position and power...
