Arthur Caplan, director of the Center for Bioethics at the University of Minnesota, could conjure up several equally defensible ways in which cloning human embryos might be medically appropriate. Suppose, for example, a woman knew she was about to become sterile, either because of chemotherapy or through exposure to toxic substances. She might consider having an embryo cloned for future use. Or suppose a couple knew that their children had a chance of inheriting hemophilia or cystic fibrosis. Researchers have developed DNA-analysis techniques to screen embryos for such disorders, but the procedures require snipping cells off embryos, a process...
Even so, the newest superconductors may have trouble making it out of the lab into commercial products. Their biggest drawback: mercury is extremely toxic. But that doesn't diminish the importance of the discoveries. By * studying the mercury compounds, Chu and other scientists can learn more about what makes molecules become superconductors and how laboratory tricks can help the process along. The research has barely begun, and countless compounds remain to be tested. Chu intends to work his way through the periodic table, looking for promising elements to mix into his superconducting concoctions. What's a likely candidate? Well, says...
Despite the highest concentration of sports teams in the world, little East Rutherford, NJ is no less of a toxic waste dump and no more of a meadow than before the Meadowlands came to town...
Everyone agrees that Lorenzo's oil cuts down on the level of toxic compounds in the blood that are understood to cause the disease. But the oil cannot reverse nerve damage, often resulting in blindness and paralysis, that has already taken place. Nonetheless, Dr. Hugo Moser of the Kennedy Krieger Institute in Baltimore, Maryland, believes Lorenzo's oil may delay the onset of symptoms. "We know that it's not 100% preventive," says Moser, who is conducting a five-year study of 80 boys who have inherited the gene for the disease but started taking Lorenzo's oil while they...
Uncle Sam's big toxic cleanup is a failure -- and a legal nightmare...
