...weapons. To have accused the U.S. of overflights would have been to admit an inability to defend the country against U.S. planes. Whether Khrushchev indeed got himself an accurate new antiaircraft rocket, or whether-as first U.S. stories had it-Pilot Powers came dangerously low with trouble in his oxygen system, the U.S., at week's end, did not know. In any event the bagging of a U-2 was a moment that Russia's bosses had long looked forward to, and Khrushchev understandably made the most...
...window in the 7-ft. diameter cone, slept only six hours a night but made up for it by lying on his back some twelve hours a day, doing nothing at all. Sheets of potassium superoxide absorbed his breath, removed the potentially poisonous carbon dioxide and released the fresh oxygen that he lived on all week. He came through so well that the space doctors are now at last ready to try the test in the weightless condition of actual space, first with animals, then with...
...smoking is dangerous and often painful for heart-attack victims was explained by researchers from Wayne State University (see EDUCATION). Patients volunteered to let them work two thin plastic tubes into their hearts and put a hollow needle into an arm artery. After three cigarettes, blood pressure and oxygen readings showed that the heart had to work much harder than usual but got little or no extra oxygen. Among the test's financial backers: the Tobacco Industry Research Committee...
...when the Sumerians spun the tale of a swimmer who sought the weed of eternal life beneath the waves. Down through the centuries, woodcuts show submerged men hopefully sucking on bags full of air or puffing on tubes reaching to the surface. Looking for something better, Cousteau tried an oxygen lung based on a design developed by the British as early as 1878. He almost killed himself. He did not know the fatal flaw of oxygen: it becomes toxic at depths below 30 ft.* Twice Cousteau had convulsive spasms, was barely able to drop his weights and make the surface...
...Oxygen lungs have one great advantage: they recycle the diver's carbon dioxide through a purifier, let no bubbles escape to the surface. For this reason they are used by military frogmen, who would be betrayed by the telltale stream of bubbles from a compressed-air lung, which discharges spent breath into the water...
