...rays or chemicals in advance to suppress the body's tendency to reject a graft from anyone other than an identical twin. For this job the Brigham doctors had decided to rely on drugs, and they used a battery of the most potent available: azathioprine (a new immunity suppressor), actinomycin C (an antibiotic used against some cancers), a cortisone-type hormone, heart stimulants, diuretics and even bicarbonate of soda. Time and again, the transplanted kidney began to fail as his body tried to get rid of this "foreign tissue." But each time the drugs...
...strong smog-control bill, aimed at smog-choked Los Angeles, requiring that cars in California be fitted with suppressors to cut down on engine hydrocarbons and carbon monoxide. Progress will be slow: first the state has to approve a suppressor design; then motorists have to get the smog-stopper installed...
Fractured Decibels. Plane builders themselves long ago recognized the noise problem, went to work developing suppressors that would cut the roar and whine of pure jet engines without cutting engine efficiency too much. Last week Boeing announced that it had licked the problem. It said that its suppressor had cut jet noise below the level promised purchasers of the 707, making it slightly less noisy than a Super Constellation. The trick was done by breaking up the jet stream and funneling it through 21 narrow after tubes instead of one big tube. "The big, doughnut-shaped exhaust roar," said...
Even the highly critical Port Authority admitted that the suppressors have reduced jet noise at the normal measuring distance to 102 decibels, about the level of a piston-engine airliner. But it has also thrown a new factor into the dispute; the Authority argued that the results of tests it had made showed that the jet noise contained a high-pitched whine that made it much more objectionable to listeners than a piston-engine plane roar of a much higher decibel reading. But the Authority's own aviation-development specialist, Herbert O. Fisher, apparently disagreed. He joined with outside...
...Senate, urged Ike to go farther, meet Zhukov face to face; such a meeting would "weigh heavily in the President's fav.or. I'm certain that the President would not be taken in." Western diplomats leaked worries that Ike's friendly remarks about Zhukov, suppressor of the bloody Hungarian revolt, might kill a U.S.-sponsored United Nations resolution condemning Soviet brutality in Hungary, might unduly alarm U.S. allies fearful of bilateral U.S.-Soviet negotiations...
