...maquiladoras, most of them American-owned, employ more than 500,000 Mexican workers. Not only has the shifting of the facilities to Mexico cost some Americans their jobs, but lax environmental standards and poorly enforced regulations have turned large stretches of the 2,000-mile border into toxic cesspools. Maquiladoras are blamed for the noxious brown cloud that often overhangs El Paso, Juarez and other cities, as well as for the foul wastes that flow into the Rio Grande...
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...
Uncle Sam's big toxic cleanup is a failure -- and a legal nightmare...
