...establishing that McVeigh was also in possession of a bomb. The most direct way to do that will be to call an FBI expert who will testify that McVeigh's clothing, tested after his arrest, showed traces of nitroglycerin and pentaerythritol tetranitrate, or petn, an explosive used in detonator cord. Prosecutors will also present evidence to show how, in the months before the bomb exploded, McVeigh set out to gather materials...
...spinal nerves from signaling the brain. But what they didn't know until the late 1980s is that these nerves are more than just glorified gatekeepers. They actually "remember" the body's past travails, causing permanent changes that are recorded in their molecular structure. "Think of the spinal cord as a voice-mail system," says neurobiologist Allan Basbaum of the University of California, San Francisco. "A message comes in and leaves something behind." The longer the injury persists, the more sensitive the spinal nerves become to painful stimuli--and the more intensely they signal the brain that something is wrong...
...that it could revolutionize surgery. In the past, most patients were put to sleep with a general anesthetic, which dulls the brain's memory of what has happened but does nothing to stop the spinal nerves from reacting. In the early 1990s, Basbaum's team showed that the spinal cord triggers a cascade of chemical and electrical signals during an operation. Once the brain comes out of its anesthesia-induced fog, it translates all this electrochemical activity into sheer agony...
Physicians have since learned how to short-circuit that chain reaction. By numbing the surgical site with a separate injection of a local anesthetic, they can prevent many of the pain signals from ever reaching the spinal cord. Then, by administering small amounts of morphine to the spinal cord once the operation is over, they can significantly reduce any pain that occurs after the local anesthetic wears...
CONCORD, New Hampshire: Michael Dorris, the author who helped spread awareness of fetal alcohol syndrome with his award winning book "The Broken Cord," has died from an apparent suicide at age 52. According to Concord police, Dorris was found in motel room and apparently suffocated himself with a plastic bag. Part American Indian, much of Dorris' writing focused on the history and plight of Native Americans. "Native Americans: 500 Years After," and "A Guide to Research in Native American Studies," are among his better known works. But his book "The Broken Cord," earned him the most notoriety with a National...
