...Yamanaka of Kyoto University to undo more than 30 years of exquisitely programmed biology packed into a woman's cheek cell - and just maybe change the world. In a procedure that some scientists thought could take decades to discover, Yamanaka tricked the cheek cell into acting like an embryonic stem cell - capable of dividing, developing and maturing into any of the body's more than 200 different cell types. And he wasn't alone: on the same day that he published his milestone in the journal Cell, James Thomson, a pioneering University of Wisconsin molecular biologist, reported similar success...
...Their papers cap a year of remarkable research, in which scientists have surged ahead of ethicists and politicians in finding ever more clever ways to generate stem cells. But where other breakthroughs relied on using cells from living embryos - tiny bits of inchoate life, fraught with ethical issues - the work by Yamanaka and Thomson sidesteps that abyss by nursing adult cells into a state in which their cellular destiny is yet to be fulfilled. No embryos, no eggs, no hand-wringing over where the cells come from and whether it is ethical to make them in the first place...
...Crimson also had nine turnovers in the first half, seven of which came in the first five minutes. This, along with good off-the-ball movement on offense, allowed Holy Cross to build at 27-12 lead with 7:48 left in the first half.Harvard was able to stem the Crusader onslaught by switching between zone and man-to-man defenses, which knocked Holy Cross off-balance and out of its offensive groove.“We needed to try to change the rhythm of the game,” Amaker said. “We weren?...
...original version of this story incorrectly stated that scientists in Seattle had cloned embryonic stem cells from monkeys. In fact, the scientists were working at Oregon Health & Science University in Portland...
...Neither Yamanaka nor Thomson believes their cells are quite ready for patients yet; for one, both methods use viruses to deliver the time-reversing genes, a practice that is acceptable in the lab but unsafe for the clinic. But the advances are finally pushing stem cell researchers to start talking about when, not if, stem-cell based therapies will be developed to treat diseases...
