...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 down and then...
...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...
Indeed much is being done. For the past three decades, the Japanese movement against the atom and hydrogen bombs has warned against the nuclear danger. In Britain and Europe the International Confederation for Peace and Disarmament has consistently worked on this issue. The World Peace Council, too, continues to push for detente and disarmament. These international movements are working closely with non-governmental organizations all over the globe to create maximum impact on the U.N. Special Assembly on Disarmament in May, 1978. There is clearly a growing international sentiment expressing the demand for zero nuclear weapons and a stop...
Died. Gersh Budker, 59, innovative Soviet researcher in high-energy physics; probably of heart disease; in the U.S.S.R. Budker, who joined the Soviet Atomic Energy Institute in 1946, did early work on graphite-moderated uranium reactors and contributed to the development of the Soviet hydrogen bomb. As director of the Siberian Institute of Nuclear Physics in Novosibirsk, he helped design a "colliding beam" accelerator-now used in high-energy physics research-in which a beam of electrons collides with a beam of positrons...
...maintained at that temperature for about one second at a density of about 1014 (100 trillion) particles per cubic centimeter. Scientists have taken two different routes in their efforts to achieve these critical conditions. One is to use a "magnetic bottle" -an enclosing magnetic field-to contain the hydrogen fuel. The other is to use lasers or electron beams to make miniature hydrogen "bombs" out of tiny pellets of the fuel...
