...candidates for the oldest-form-of-life title are organisms that scientists have dubbed "archaebacteria." They are found in airless recesses like Yellowstone National Park's hot springs, thrive in temperatures ranging from 65° to 70° C. (150° to 170° F.), take in carbon dioxide and hydrogen, give off methane gas, and have been known to scientists for years. But it took the efforts of a team led by Geneticist Carl Woese of the University of Illinois in Urbana to demonstrate that the archaebacteria had an extraordinary characteristic. Using enzymes, or chemical catalysts, they broke...
...unique genetic structure suggests that there may be a third line of evolution. It also provides an important clue to the earth's early environment. Scientists have long believed that for about the first billion years after the formation of the earth, the atmosphere consisted largely of hydrogen, carbon dioxide and other gases, but virtually no free oxygen. The life-style and genetic structure of Woese's archaebacteria tend to support the theory; because the strange bugs now live only in remote, airless niches of the environment and die when exposed to free oxygen, they may be little...
Even more surprises were in store. After World War II, the radioactive carbon-14 dating method was developed...
...mills in several cities. Steelmen have long complained that much of the foreign metal is being "dumped"-that is, sold in the U.S. below the cost of production. But little was done about the problem until two weeks ago, when the U.S. Treasury accused five Japanese steelmakers of dumping carbon plate and ordered them to post bonds totaling $50 million to cover penalty tariffs that Treasury might later assess against their products...
...Carbon Edge, the Orange force (played by some U.S. and West German units) took the role of the Soviet-led Warsaw Pact. Reflecting its impressive firepower advantage on the Central European front, Orange quickly penetrated the Blue lines, raced 40 miles and crossed the upper Danube. After falling back and regrouping, Blue counterattacked; its main forces hammered away across the invader's broad front, while airborne rangers hit Orange from behind. When the exercises ended, Blue had clearly triumphed...
