...same time, Harvard has opened another battleground in the search for cells. After exhaustive ethical review, its researchers announced this summer that they would develop new cell lines through somatic cell nuclear transfer, or therapeutic cloning. In this process, a cell from a patient with diabetes, for instance, is inserted into an unfertilized egg whose nucleus has been removed; then it is prodded into growing in a petri dish for a few days until its stem cells can be harvested. Unlike fertility-clinic embryos, these cells would match the patient's DNA, so the body would be less likely...
...long-term promise is boundless, but the immediate barriers are high. The only people who claim to have succeeded in creating human-stem-cell lines through nuclear transfer were the South Korean researchers who turned out to be frauds. It will take much trial and error to master the process, but where do you get the human eggs needed for each attempt, particularly since researchers find it ethically inappropriate to reimburse donors for anything but expenses? And even if the technique for cloning embryos could be perfected, would Congress allow...
...get around political roadblocks, scientists are searching for another source of cells that is less ethically troublesome, ideally one that involves no embryo destruction at all. One approach is "altered nuclear transfer," in which a gene, known as CDX2, would be removed before the cell is fused with the egg. That would ensure that the embryo lives only long enough to produce stem cells and then dies. That strategy, promoted by Dr. William Hurlbut, a member of the President's Council on Bioethics, has its critics. Dr. Robert Lanza of biotech firm Advanced Cell Technology considers it unethical to deliberately...
...Regime did not include China or any Middle Eastern nations; in fact, the only Asian country that has signed it is Japan and the only African country that has signed it is South Africa. But with Security Council passage of two provisions that "require" U.N. members to prevent the transfer of "missile and missile-related items, materials, goods and technology" to North Korea and to prevent North Korea from selling missile-related items and know-how," says a State Department arms control specialist, "now there's no gray area with regard to North Korea...
Three days into their mission, the transfer case in her five-ton truck "just busted"--and she and her sergeant were stranded. For a few bleak heartbeats, it looked as if her little girl's fear was real. Then a humvee swerved off the road, and the driver beckoned to her. "Get in." It was Private First Class Lori Ann Piestewa, her best friend. The sergeant hopped in another truck, and they rolled on. A Hopi from Arizona who had been Jessica's roommate at Fort Bliss, Texas, Lori was recovering from an injured shoulder and had been given...
