...Advanced Cell Technology—a biotechnology company based in Worcester, Mass.—takes one cell from a developing embryo when it is at the eight cell stage and uses this cell to create a new stem cell line. The remaining seven cells retain the ability to implant into the uterus and develop into a normal fetus.The second method, known as alternative nuclear transfer and published by MIT researchers, creates embryonic cell lines from cells that were engineered to have a temporary defect in them, rendering them unable to implant into a uterus.Such cells are not implantable...
When my editor asked me to write an article for the What's Next issue, I panicked. I foresaw long hours in laboratories trying to interpret the jargon of scientists finding new ways to map the brain, implant RFID chips in my skin or create a tofu that fails in its attempt to taste like yet another kind of meat. What, I pondered, would be the easiest subject I could tackle? What never changes? The answer suddenly seemed obvious: What's Next ... with the Amish. How hard could that be? I could report and write the piece while watching television...
...incubate them to maturity in the lab. But because very few dog eggs will mature outside of a dog, viable eggs have to be extracted surgically. Once you have inserted the DNA you want to clone and tricked the eggs into becoming embryos, moreover, you can't just implant them at will in a surrogate bitch. Cows, goats and sheep can be thrown into estrus--readiness for pregnancy--by giving them a hormone shot. Not dogs. "You have to monitor hundreds, if not thousands, of dogs every day to figure out when they come into heat," says Westhusin. That...
Rice believes this is her moment. In pep talks to State Department colleagues, she compares the Administration's drive to implant democracy in the Middle East to the policies devised by Marshall's generation to combat communism in Europe after World War II. She delivers major speeches on university campuses, rather than in ministerial chancelleries, and seeks out audiences receptive to her declarations of moral purpose. "Our greatest achievements are yet to come," she told French students in Paris. "We must provide greater prosperity to people all over the world," she said in Tokyo. "We are supporting the democratic aspirations...
Nonetheless, the Schroeders do feel that the families of any future recipients should be given a clearer idea of both what to expect and what will be expected of them. Particularly important, says Mel, is that implant candidates discuss with their families in advance what actions to take if disabling complications occur and the patient's quality of life becomes marginal. Says he: "We thought it was going to be either yes or no. That he was either going to live or die." No one counted on a state of existence somewhere in between. --By Claudia Wallis.
