With the artificial heart in place, Cooley led these tubes out through the cut in Karp's chest wall. The heart-lung machine was switched off and the console switched on. At a slow-normal heart rate, the pump alternately sent a volume of carbon dioxide under pressure into sacs in the artificial heart to force blood out of the ventricles to the lungs and the rest of the body, then relaxed this pressure to let the heart refill with blood...
Contemporary scientists have been far less convinced that Mars has water. They believe that the caps consist not of snow or ice but largely of frozen carbon dioxide, the principal constituent of the atmosphere of Mars. Some have suggested that the color changes are due to unknown chemical reactions, or to seasonal winds that alternately deposit sand from bright lowlands onto the dark highland surfaces and then blow it away. Their views have not been contradicted by spectrographic studies of the Martian atmosphere. Although some of these studies have detected traces of water vapor, the evidence has not been distinct...
...potential fault was found in 2.4 million Chevrolets built between 1965 and 1968. Lethal fumes from damaged or aged exhaust pipes have, in a few models, seeped into passenger compartments through opened seams and defective plugs in the underside. There have been 30 reported cases of such leakages, and carbon monoxide was blamed for four deaths in Chevrolet Impalas. Another possible danger in some 20 models is a plastic cam, used to regulate the engine's idle speed, that has at times broken and dropped into the throttle linkage, jamming the accelerator and making it difficult to stop...
Everybody talks about the good old days in the U.S. at the turn of the century. One gentle but impassioned lady, Dr. Alice Hamilton, remembers it differently-as a grim time when men were immobilized by carbon monoxide gas in steel mills, women suffered brain damage from lead used in the pottery trade and thousands of workers were crippled and died from the inexorable accumulation of poisons in dozens of industries. Almost singlehanded, Dr. Alice drew state and federal attention to the horrors, aroused public indignation and campaigned across the nation until-finally-a body of laws was passed...
...days after other aquanauts set up housekeeping aboard Tektite, a second undersea habitat that had been lowered into Lameshur Bay at St. John, V.I., one of four fire extinguishers began to leak carbon dioxide into the cabin. It was quickly placed outside. The following day, the unit that had detected the carbon dioxide ceased to function. But Tektite technicians began hourly atmosphere checks to ensure the safety of the aquanauts and expressed confidence that their mission would continue successfully for its scheduled two-month duration. If everything goes according to plan, the aquanauts hope to complete underwater biological and geological...
