...designed to prevent the escape of potentially dangerous organisms. But there is always the chance that something or someone will fail-and that a few virulent bugs will slip through the safeguards to multiply in the outside world. Faced with this problem at the Asilomar conference. Geneticist Roy Curtiss III proposed an ingenious solution: Why not convert the standard genetic research organism, a strain of the E. coli bacterium, into a seriously weakened mutant variety that would quickly self-destruct if it escaped the laboratory? Curtiss volunteered to engineer the new bug, and his colleagues agreed to hold...
Returning to his laboratory at the University of Alabama Medical Center in Birmingham, Curtiss quickly hit on a way to keep E. coli under control. The microbes must be able to manufacture a protective membrane; without such an outer coat they would swell and burst during normal growth. To keep them from manufacturing a complete coat, Curtiss created an E. coli with a defect in a gene that makes diaminopimelic acid (DAP), an important ingredient of the membrane. The defect made the bugs dependent for their survival upon DAP supplied by scientists...
...already revving up to cut themselves in on the profits. Except for General Motors, which in 1970 bought a license to make Wankels in a deal that will eventually cost it $50 million, any manufacturer who decides to build a rotary engine will presumably have to pay royalties to Curtiss-Wright Corp., which owns North American patent rights to the design. Largely on the strength of that asset, Curtiss-Wright stock shot up from 1 ⅜ to 59 ¼ earlier this year, though it has settled back in recent weeks to around 45. Officers of machine tool firms are hoping...
...four and my most vivid recollection of the event was my impression of the airplane as I first saw it from our upstairs dining-room window. The Curtiss pusher type, with its framework fuselage, looked from sideview exactly like a giant safety...
Died. Alfred V. Verville, 79, pioneer aircraft designer who in 1914 with Glenn Curtiss designed the famed Curtiss Jenny, and later as a U.S. Army Air Service engineer developed the nation's first welded-fuselage fighter plane with droppable fuel tanks, the PW-1 Pursuit; of a heart attack; in La Jolla, Calif...
