...neurons that make up the adult central nervous system do not divide and multiply. Once they die, they cannot be replaced -- a fact that makes brain and spinal damage so devastating. But, in an unprecedented experiment, scientists at the Johns Hopkins School of Medicine chanced upon a kind of human brain cell that could be nourished and cultivated. The researchers have kept a laboratory culture of the neurons alive -- and multiplying -- for nearly two years. The new technique, reported last week in Science, should make it easier for scientists to study how the cells function and could someday lead...
...first step in this line of research, Snyder is considering injecting altered cells into the brains of rats. It will be years before similar experiments can be done in humans. But in the meantime, the new technique promises great advances in knowledge of how the human mind works...
During California's war against the citrus-destroying Mediterranean fruit fly, community groups have beseeched state officials to stop spraying the insecticide Malathion in populated areas. But the bureaucrats at the California department of food and agriculture refused, insisting that the . spraying poses no threat to human beings. Now at last the state's anti-medfly force has been induced to yield a bit -- to avoid possible harm to an endangered species named the Stephens' kangaroo...
...Only in the sense that every species is. Since evolution has no inherent or predictable direction, if you could play life's tape again from any early point, you would get a completely different result that wouldn't include human beings.
