...DIEGO: A neurobiologist in California has found a way to implant the natural behavior of one animal into an entirely different species. The breakthrough, published in the Proceedings of the National Academy of Sciences, comes just a week after scientists stunned the world by cloning an adult mammal and further demonstrates science fiction's uncanny knack for becoming reality. In the experiment, a chicken was made to act like a quail by transferring certain brain cells from a quail embryo to the brain of a chicken embryo. Once hatched, the chicken's movement's resembled those of a quail...
Silicone breast implants have been blamed for virtually every ailment imaginable--muscle aches, joint pain, mysterious rashes, even serious autoimmune diseases like lupus and scleroderma. So it is little wonder that implant lawsuits have clogged the nation's courts and forced one manufacturer, Dow Corning, to seek pre-emptive bankruptcy. Yet many medical and legal experts have long suspected that the blame laid on implants is based on "junk science." Last week, in a bold opinion that surprised legal experts across the country, a federal district court judge in Portland, Oregon, endorsed that view. Expert testimony linking implants...
Although Jones is handling only 70 breast-implant cases, his opinion is expected to exert considerable influence on other judges who are grappling with similar suits brought by thousands of women. One reason: Jones took the unusual step of appointing four independent experts to assess the purported link between the rupture of silicone implants and specific physical complaints. These experts--an immunologist, an immunologist/toxicologist, a rheumatologist and a polymer chemist--arrived at the same conclusion reached by many others, including Dr. Marcia Angell, executive editor of the New England Journal of Medicine: localized problems, notably the painful hardening of breast...
...courts have long struggled with the problem of expert witnesses who champion theories not accepted--and sometimes hotly contested--by the majority of scientists in their field. Breast-implant suits, for example, have produced a brand-new affliction, "atypical connective-tissue disease," that has as yet no formal medical standing. Argues Dallas attorney Bert Black, who heads the American Bar Association's section on science and technology: "One should not force companies to pay out millions of dollars and drive useful products off the market on the basis of a disease that isn't even a hypothesis yet." But University...
From headache sufferers to cancer patients, 50 million Americans live with pain, sometimes mild, sometimes crippling. Researchers are currently testing, in animals, a more convenient and safer way to deliver relief. Taking their cue from the birth-control implant Norplant, which is inserted under the skin and provides long-term contraceptive protection, researchers have packed a button-size insert with a powerful narcotic. Implanted under the skin, the device releases analgesic into the bloodstream continuously for three months. Tests on cancer patients will begin within a year...
