...totally innocent victims in the tragic Israeli-Palestinian conflict, it is Israel which dominates and oppresses the Palestinians, not the reverse. There is no possible justification for Israel's heinous actions, and the rabbis do a great disservice to all involved parties by obscuring and implicitly excusing them.

...work with fetal tissue was by far the more elaborate of the two research efforts. Led by Stanford's Dr. Mike McCune and Irving Weissman, the scientific team actually reconstituted a human immune system in mice that lacked their own immune systems. Because of a genetic abnormality known as SCID (for severe combined immunodeficiency), these mice usually die at an early age, often of pneumocystis pneumonia, the disease that kills many AIDS patients. The researchers implanted some 300 of the defective mice with tissue taken from human fetal thymus, where certain immune and blood cells develop, and with blood-forming...
...Stanford mice are still thriving. Their new immune systems, however, must be sustained by injections of fetal liver cells every eight to twelve weeks. In addition, researchers are not sure whether all the parts of the human system are functioning in the mice. "We'll find that out," says Weissman, "but we'll have to do every known test for human immune cells. These mice open ways of studying human systems, normal or diseased, under experimental circumstances that were impossible before...
...cell, dying, leaks out its insides. To ensure that the cell and its viral occupants are destroyed, the killer T cells then deliver the coup de grace by transmitting a signal that causes the cell to chew up DNA from both itself and the virus. Explains Dr. Irving Weissman of Stanford: "This is an overlapping, dual system of killing that ensures that the seed of viral production will be eliminated from the body...
