acoustics. He and his colleagues are starting an experiment called ATOC, acoustic thermometry of ocean climate. He hopes to detect greenhouse warming this way.Swiss scientists recently built two identical greenhouses. In one, the carbon dioxide level was close to that of the present day ; in the other, the level was increased to what it will be in the next century if the present rate of ...
of small blood vessels. The resulting blockage damages tissues, especially the brain and kidneys, but there's now hope of someday preventing this. Recently cell biologists at Washington University, St. Louis, in the United States, have found that when inside red blood cells, the parasites develop special channels for taking in nutrients. Researchers expect to find ways of blocking these ...
