...Viking landers. The gas exchange test, based on the fact that terrestrial organisms give off gases as waste products, involved dropping a pinch of Martian soil into a warm, moist test chamber. The aim was to determine whether the sample would give off carbon dioxide, as animals would, or oxygen, as plants do. Scientists were surprised when the sample began releasing oxygen far more rapidly than plants would be expected to do. But they noted that the reaction might have a purely chemical, rather than a biological explanation; compounds called peroxides could have released the oxygen if they were present...
Puopolo had suffered extensive brain damage from a lack of oxygen after he was stabbed. The respirator which was keeping him alive was still attached when he died at 4:12 a.m., after a 31-day coma...
Sudden Death. The primary cause of this breathing failure remains unclear, though sometimes it appears to be linked with obesity. In any case, drowsiness is only the mildest byproduct. The disorder can lead to hypoxia (low blood oxygen), hypertension (high blood pressure), heart disease and in some cases sudden death. Nor is it easily treatable. Conventional sleeping pills can actually worsen the problem by increasing the breathing difficulty. Removing the tonsils and adenoids to make a larger breathing passage seems to work only in children. Shedding weight makes little difference. Jokes the still overweight Siegel: "I've lost...

With this ritual observed, someone took off the oxygen mask so Hughes could be moved. Gordon Margulis lifted the frail seventy-year-old billionaire, as light as a child, and put him on a stretcher. He and an aide carried it to the service elevator. Margulis raced back, wrestled the huge oxygen cylinder aboard, and Hughes was put back...
