Besides the various amino acids, Ponnamperuma's team detected a greater proportion of carbon 13 than would be present in earthly organic matter. It also found a mixture of hydrocarbons curiously like that produced in experiments simulating the conditions of a primitive planetary atmosphere. The most compelling evidence was the nature of the amino acids themselves. Ever since Louis Pasteur's day, chemists have known that the atoms of organic compounds like amino acids can be assembled in two ways-one a mirror image of the other. Yet except for those made artificially, most amino-acid molecules found...
Each year, 50,000 U.S. infants die soon after birth-at least 25,000 of them from respiratory distress syndrome (RDS). Also called hyaline membrane disease, RDS is caused by the inability of an infant's lungs to extract oxygen from the air and pass carbon dioxide out of the body. Even when such babies (most of them premature) survive, they may suffer permanent brain damage...
...since 1929, mainly because dams and irrigation projects along the Volga and Ural rivers divert incoming water. As a result, Russia's caviar output has decreased; one-third of the sturgeons' spawning grounds are high and dry. Meanwhile, most municipalities lack adequate sewage treatment plants, carbon monoxide chokes the plateau towns of Armenia, and smog shrouds the metallurgical centers of Magnitogorsk, Alma-Ata and Chelyabinsk...
...fitting bureaucratic style, the coronation of "Miss Bureaucrat 1969" last week was followed, a few moments later, by the crowning of "Miss Carbon Copy," her twin sister. Both presided over the presentation of awards for extraordinary bureaucratic finesse. Winners received a gold-painted, potbellied, disheveled bird, sculpted by Boren himself. Among the recipients were ex-Ambassador to Panama and former Peace Corps Director Jack Hood Vaughn and John Brayton Redecker, a State Department official and author of CASP: A Systematic Approach to Policy Planning and Analysis in Foreign Affairs. Absent was Vice President Spiro Agnew, tapped for "his contributions...
...Birds. Rolls-Royce's troubles are those of a cash-short player trying to keep up with the international competition. Its financial troubles have been compounded by technological problems encountered in developing the TriStar's engine. Rolls-Royce's pioneering use of "Hyfil"carbon fibers laminated with resinfor fan blades produced an engine that was lighter and more economical on fuel. But the Hyfil blades were vulnerable to damage by birds drawn into an engine during takeoff or flight. A 4-lb. bird makes an impact equivalent to two tons on a spinning turbine...
