to the brain becomes blocked by a clot. As a result, part of the brain fails to get the oxygen it needs, a condition that damages nerve cells. The effects of a stroke, which can include paralysis and problems with language and vision, depend on sever...

from contaminated sites with little or no bacterial activity also could reveal ways to coax poor PCB-eaters into developing healthy appetites for these toxins. Ultimately, PCB-digesting microbes will need to be examined in each contaminated lake or r...
