...Lakebergs' time of hard choices began just before Christmas. About 13 weeks into Reitha's pregnancy, the Wheatfield, Indiana, couple learned through an ultrasound test that she was carrying Siamese, or conjoined, twins. Such cases are rare; they happen when a fertilized egg splits incompletely during early cell division. About 40 such sets of twins -- or 1 in 50,000 births -- occur in the U.S. each year. Few of the pairs live long enough for separation to be considered. The Lakebergs' doctors had put the likelihood of one twin surviving at no more than 20% and suggested an abortion...
Kids, don't try this at home: Penn State University scientists have created thin layers of diamond by the unlikely technique of cooking carbon-rich plastic, mixed with potassium and sodium and blasted with a beam of ultrasound, at low temperature in a regular home oven. The result is a low- grade but authentic form of diamond. If the quality can be improved, plastic-derived diamond could provide a cheap, strong coating for everything from airplane windows to drilling tools...
...rectal exams. But what if the tests seem to contradict each other? It is not unusual to have a PSA level in excess of four-billionths of a gram per milliliter and a rectal exam that reveals nothing. In that case, the next step might include further observation, an ultrasound exam or even a biopsy, a procedure in which bits of tissue are removed from the prostate and examined under a microscope. Should men with high PSA levels undergo expensive, anxiety-producing biopsies year after year to make sure they do not have cancer? Not necessarily. More important than...
Other elements of Zimmerman's physical therapy, which started at the beginning of the fall season, included one and a half hours in the training room bicycling, leg stretching and ultrasound. Meanwhile, Fish gradually increased the amount of time Zimmerman spent on the court...
...Although ultrasound tests are used almost routinely on fetuses, Dr. Curt Bennett, professor of pediatrics at the University of Washington, says there is a possibility that the baby tapes could be harmful. "Sound waves that are too intense might have fetal consequences," he says. The better-baby belt, he adds, "is an intervention after all, and it does have the potential to be risky...
