...carried the crucial interferon DNA? Analyzing them in successively smaller groups-first 500 at a time, then 64, then eight-the scientists isolated their genetic needle in the haystack: the bacteria that carried the DNA for interferon. After they found one such bug, they could easily identify others and extract the DNA fragments. The team spliced them into different places in E. coli, and, presto, the bacteria began cranking out a close facsimile of the human protein...
...develop secondary and tertiary sources, many of which will become both economically feasible and absolutely necessary as conventional minerals become costlier in the 1980s. For example, the U.S. imports 93% of its bauxite, the major aluminum ore, but the Bureau of Mines is experimenting with a process to extract alumina from clays found in Georgia and Arkansas. More experiments, more domestic mining and some compromises on the environmental front would help avoid repetition of the oil saga of the 1960s and 1970s, when the U.S. became needlessly overdependent on dubious foreign suppliers. In an era of growing economic confrontation, increasing...
...have different internal causes of instability but cumulatively are facing widespread regional turbulence. The Soviet Union has chosen both to exploit that turbulence and to project its power into it. This is likely to be highly destabilizing for all of the neighbors of Afghanistan. The Soviets may hope to extract some benefits from it, but they should be increasingly aware that international stability and restraint are more in their own interest...
...York's Empire Buying Service, Owner Jack Brod was importuned by one eager customer to extract his loose, gold-filled tooth on the pot. Brod refused; the man left, but returned a few days later with tooth in hand. Typically, New York Dealer Harry Rodman paid one Maryland dentist $500 for the gold scrap and dust that he had collected with a special vacuum from dental grindings in just two years of practice. Dealers also quietly bought gold fillings from morticians, proving that you can't take it with...
...restricting the spread of weapons-grade plutonium is to limit the spread of nuclear breeder reactors, which produce plutonium, and reprocessing plants, which extract plutonium from the spent fuel rods of conventional reactors. President Carter has tried to pursue this policy--in exactly the wrong manner. Many harder hit by OPEC's price hikes than any industrialized country, less developed nations, see nuclear power as the only hope for attaining energy self-sufficiency. These had depended upon the United States to develop the breeder reactor and nuclear fuel reprocessing technologies for them to guarantee a future supply of nuclear fuel...
