...culprit was deregulation, which, students of the telephone and airline industries will tell you, doesn't always go according to plan. When states started breaking up one of the last subsidized monopolies a few years back, they hoped to usher in a wave of competition that would lower prices, improve service and increase the system's reliability. Newly liberated customers would be able to choose from a host of suppliers, some of whom generated the power while others just delivered...
Almost overnight, it seemed, scientific interest in the genetics of beta amyloid exploded. Researchers had long been aware that early-onset Alzheimer's, while rare, often ran in families. Could it be, they wondered, that the culprit was a mutant version of the APP gene? In 1991 scientists at London's St. Mary's Hospital Medical School screened the DNA of an Alzheimer's family and found what every geneticist in the field had been furiously looking for. The mutant APP gene sat on chromosome 21, and the single change in its DNA sequence occurred in the vicinity...
...century-old mystery is on the verge of being solved. As researchers, physicians and caregivers gather in Washington next week for the World Alzheimer Congress, the scientists who favor plaques as the culprit are getting a first crack at proving their hypothesis. Thanks to a series of discoveries--some of which have been made only in the past couple of months--they should soon be able to demonstrate once and for all whether getting rid of plaques is the most important step in halting the progression of Alzheimer's disease. They've already started preliminary clinical trials in human volunteers...
SEIZE THIS! Been told you have epilepsy, but can't get the disease under control? Now a report suggests that as many as 25% of patients thought to have epilepsy are actually suffering from low blood pressure, heart-rhythm problems or panic attacks. Clues that epilepsy is not the culprit: the attacks usually come when the patient is sitting or standing, and--no surprise here--epilepsy medication doesn't help...
...primary culprit" for the error was an anonymous government clerk, the Pentagon says. The bureaucrat mistakenly added all nonbattlefield U.S. military deaths--20,617--that occurred worldwide during the three-year conflict to the more than 33,000 U.S. battlefield dead in Korea. But only 3,275 of those nonbattlefield deaths--largely due to accidents or disease--occurred in Korea. That yields the new, revised U.S. death count for the war. In a rare example of interservice cooperation, a Pentagon memo notes, "All service historian offices have been advised...and are in agreement with the revision...
