...that, when sufficiently provoked, consumes a person with rage, thirst, hunger or desire. In animals, a region at the front of the organ controls sexual function and is somewhat larger in males than in females. But its size need not remain constant. Studies of tropical fish by Stanford University neurobiologist Russell Fernald reveal that certain cells in this tiny region of the brain swell markedly in an individual male whenever he comes to dominate a school. Unfortunately for the piscine pasha, the cells will also shrink if he loses control of his harem to another male...
...patients would have been given the drug under close scrutiny. But the advisory panel's vote on lack of efficacy made the plan moot for now. "There was concern that a very bad precedent could be set if the scientific standards were lowered," says Steven Ferris, a neurobiologist at New York University Medical Center, who chaired the committee. The group has recommended another study of tacrine's effectiveness. In the meantime, the FDA is hewing to the line that, as with any drug, benefits must clearly outweigh risks...
Scientists are also exploring ways of resetting the body's clocks. Among the possible methods: using exercise, changing diet, or varying the amount of light or sleep. Even chemical intervention is being considered. Says neurobiologist Fred Turek of Northwestern University: "One of our goals is to find safe drugs that can speed up your clock or slow it down." Such techniques offer the possibility that one day, humans will be not just captives but masters of biological time...
...Geneva Protocol did not precipitate an enraged outcry from the 105 nations that have signed the ban on chemical weapons through the years, nor did it inspire any attempt to bring Iraq before the International Court of Justice. Despite "major acts of genocide," says Steven Rose, a neurobiologist at Britain's Open University, "the fact is, Iraq has got away with...
Whether or not the recoveries prove to be long lasting, University of Rochester Neurobiologist John Sladek and Yale Psychiatrist Eugene Redmond see a braver new world ahead. The two scientists reported reversing the effects of Parkinson's in adult African green monkeys by implanting cells from the substantia nigra of monkey fetuses, and believe that fetal brain grafts offer a better bet for Parkinson's patients. Vanderbilt researchers, using fetal nerve-tissue implants in experiments with rats, also reported progress in reducing chemically induced symptoms of Huntington's disease, a fatal genetic brain disorder. Others expressed hope that once...
