A pioneer in cryobiology -- the study of extremely low temperatures on living things , discovered in Antarctica that certain fish produce an antifreeze molecule that lowers their freezing point enough to survive Antarctic waters . His third wife, biologist Chris Cheng, collaborates with him at their base at the University of Illinois, trying to isolate the fish gene that makes antifreeze proteins. Scientists are testing to see whether the ice cap there is beginning to collapse . If so , they warn , a world warming cycle may be underway . And last , because Antarctica is one of the driest places on earth , thus enabling some telescopes to better see cosmic rays , this is one of the best places on earth to study that leads to one of the central paradoxes of cosmology .
