...Omen Following the recent abduction and murder of two 10-year-old girls in England, a cybernetics expert offered to implant tracking microchips in children so they can be located if they're abducted...
...more easily, and less invasively, replace knee ligaments with cadaver tissue than with a portion of a patient's own hamstring or tendon. Of course, the risk of infection can never be eliminated in any operation. But it can be managed. Ultimately, patients must weigh the risks of an implant against the benefits. It's like driving a car, says Dr. Rick Hammesfahr, an orthopedic surgeon in Atlanta. "The probability of an accident is low, and the probability of dying in an accident is lower," he says. "Does that mean we should ban cars?" --Reported by Greg Land, Greg Fulton...
...necessarily. An advisory panel to the Food and Drug Administration (FDA) last week reviewed new safety data on saline implants, which were approved by the FDA only two years ago. (Silicone-gel implants were never formally approved and are now available only in medical studies.) The review is timely. More than 200,000 women went under the knife last year to acquire bigger breasts. That's five times the number a decade ago. And 80,000 had implants after mastectomies. What could be worrisome about a sac of salt water? Plenty, according to the FDA hearings: more than...
...cloning advocates. We would never countenance such work in humans, they say. Cows, yes, but we would never implant a cloned human embryo in the uterus of a woman and grow it to the stage of a fetus. We solemnly promise to grow human clones only to the blastocyst stage, a tiny 8-day-old cell mass no larger than the period at the end of this sentence, so that we can extract stem cells and cure diseases that way. Nothing more. No fetuses. No implantation. No brave new world of fetal farming...
Well, the cow experiment shows the way to even more human betterment. Fetal tissue offers a far simpler and more promising way to produce replacement tissues--it skips all the complications of stem-cell biology and gives you tissue that you can implant right into the human patient. Millions are suffering, are they...
