...appetite for the metabolite called uracil, the University of Wisconsin's Dr. Charles Heidelberger set about making a phony variant of uracil. With Dr. Robert Duschinsky of Hoffmann-La Roche, Inc., he quickly found a way to make one by substituting an atom of fluorine for one of hydrogen at the No. 5 position on the molecular ring-hence, 5-fluorouracil. Many of the cancer cells accept 5-fluorouracil in place of the real thing, and cannot multiply...
...four years and two months after the first U.S. test at Alamogordo, N. Mex.. in July 1945. The Russian test involved a primitive fission bomb similar to the two U.S. bombs used in World War II, but the Russians must have started work immediately on the more advanced hydrogen bomb. On Aug. 12. 1953. they exploded their first test H-bomb, only nine months after the first U.S. H-bomb test at Eniwetok Island in the Pacific...
...Liberty Bell 7 approached its apogee, traveling at 5,310 miles per hour, Grissom took manual control with a new and hopefully more precise set of controls. Weightless by now, he found the manual controls sluggish, had difficulty turning his capsule by means of its small hydrogen peroxide rocket nozzles. "Having a little bit of trouble with the manual controls," he reported. Seven minutes after launch, he managed to point the capsule and fire the retrorockets. They slowed his speed only slightly, but if he had been in full orbital flight, they would have curved him down into the atmosphere...
Some of Khrushchev's recent thunder took the form of an astonishing remark to Britain's ambassador in Moscow, Sir Frank Roberts: he boasted that he had all Western Europe at his mercy. Only six hydrogen bombs would be needed to wipe out Britain, said Khrushchev, and nine more would take care of France as well...
...Fort Eustace, Va. a helmeted engineer from Bell Aerosystems Co. leaped a truck with a "rocket belt." With 100 lbs. of tanks, tubes and nozzles strapped to his back, he began his flight by flexing his knees and turning a valve. With an earsplitting racket, superheated steam from decomposing hydrogen peroxide jetted out of two down-pointed nozzles and slowly lifted him off the ground. In a 15-sec. flight he cleared the Army truck and made a perfect two-foot landing 150 ft. from his takeoff. The Army, which is paying for Bell's Rocket Belt, is still...
