...tried to lessen censorship, and helped to establish an international forum for national literature. But at its most portentous, the group can suggest a second-rate graduate school, where the lecturers outnumber the students. Even some of the much honored guests seemed resigned to unending seminars filled with such marrow-chilling words as alienation and creativity...
...member of the executive committee of HSCI, testified before the U.S. Senate Commerce Subcommittee on Science, Technology, and Space in September 2004. He spoke about the limitations of adult stem cell research, saying that it had been successful in certain instances—exemplified by bone marrow transplants—but that scientists need to move forward with experiments on embryonic stem cells...
...bodies of all the babies accepted the grafts, a big advantage over rejection-prone bone-marrow cells, also used in transplants. But the results were uneven after that. More than half the kids who were already showing Krabbe's symptoms died from infections or other transplant complications...
What excites scientists about the unspecialized stem cells is their potential to develop into any type of tissue, from bone and muscle to skin and blood and nerve. Although there are several kinds of stem cells--including ones found in adult bone marrow and umbilical-cord blood--the most versatile, researchers say, are the ones that come from embryos, because they haven't yet developed enough to specialize at all. Those are the ones that scientists believe hold the greatest potential for treatment of a wide range of diseases, as well as for repairing damaged nerves and organs...
...genes can be so readily turned on, for example, the new technique may reveal ways to turn them off. And what is learned about gene expression could be applied to human gene therapy, in which people born with defective genes will have a "good" gene introduced into their bone marrow to produce the missing proteins. If all goes well, such therapy will begin on victims of blood disorders and enzyme deficiencies within five years. --By Natalie Angier. Reported by David Bjerklie/New York
