...survivor's good fortune involved more than plain luck. Dennis Chin of Su-Bum told reporters that he had been lying on his bed when the choking gas descended. As he gasped for air, Chin dragged himself to a windowless shed behind his house, where presumably there was enough oxygen to enable him to wait out the calamity...
...animals trapped in Russell Lake are almost certainly doomed. Freshwater from the mountain streams sits atop the denser salt water, with little mixing. As a result, oxygen, which is replenished at the surface through diffusion, cannot be replaced once it is depleted from the salt water. Fish and crabs might last for a year, but the air-breathing sea mammals that eat them will not. "The seals are exhausted from diving through that extra 50 ft. of freshwater before they can reach salt water and maybe find something to eat," says Marine Biologist Tamra Faris of the National Marine Fisheries...
...procedure was remarkable mainly because skeletal muscle and cardiac muscle are structurally different. Heart muscle works continuously, using oxygen at a steady rate. It never tires. Skeletal muscle is designed for short bursts of intense effort and fatigues easily. Ten years ago, while operating on a patient whose pacemaker had slipped out of place, Magovern made a chance observation. The patient's chest muscle, stimulated by the misplaced device, had doubled in size and showed no signs of fatigue. Other researchers independently proved that skeletal muscles actually come to resemble their cardiac counterparts when electrically conditioned...
...operations were needed because massive radiation destroys vulnerable bone-marrow tissue. The vital substance acts as the body's production center for blood cells that carry oxygen, help to cause clotting and provide immunity against disease. Victims of damaged marrow can die within weeks of severe anemia, hemorrhaging and infection. To transplant the tissue, physicians use a syringe to draw out healthy marrow--usually from a donor's hipbone--and inject it into the patient's bloodstream. The marrow cells make their way naturally to the interior regions of bones. For the procedure to succeed, the tissue of the donor...
...outside air rushed in, oxygen in the atmosphere would have fueled a raging fire in the graphite, which burns like coal when ignited, throwing a plume of volatile radioactive elements into the air. U.S. officials calculated that the particulates and gases surged nearly a mile high, where they were caught by prevailing winds and then blown over a wide swath to the northwest...
