...established her American reputation in 1966, the La Scala Siege made her an international star. Last week one could see and hear why. In lesser hands, Rossini's florid vocal writing might be just that-little more than tedious vocalizing. With Sills, a mistress of bel canto, each triplet, each double-octave run, each pianissimo high note was given musical and dramatic meaning. At one point in the second act, she sang lying on her back on one of Maometto's couches. At another, she held a soft high D while strolling away from the audience. None...
...CRICK'S team at Cambridge proved Gamow's ingenious "triplet" theory. They demonstrated that RNA formed from only one or two base units could not effect the manufacture of proteins. But when they added a third base unit, protein formation began immediately. It remained, however, for an unknown young biochemist named Marshall Nirenberg, at the National Institutes of Health, to crack the code itself. That same year Nirenberg had succeeded in building up short, synthetic strands of RNA out of only one type of base. Invariably, this artificial RNA induced the manufacture of chains of proteins consisting of only...
...most obvious deformities result from chromosomal abnormalities. Down's syndrome, or mongolism, which occurs once in every 600 births, is caused when one set of chromosomes occurs as a triplet rather than a pair. Hydrocephalus, or water on the brain, and polydactyly, the presence of extra fingers or toes, also result from faulty genes...
...past, letting Astronauts Shepard and Mitchell keep a steadier fix on their target. Although the landing will still be essentially under computer direction, Shepard will probably take over the vertical controls at an altitude of 300 ft. The actual touchdown, in a flat region between small features called Triplet and Doublet craters, should take place at 4:16 a.m. E.S.T. Friday...
...ridge at the approach to their landing area. Ahead will be a curious horseshoe-shaped feature called Weird Crater. Lovell, who has logged more time in space than any other man (572 hr. 10 min.), will probably attempt to set down between two groups of craters named Doublet and Triplet. If he overshoots his prime target, he may try for one of two nearby alternative landing sites picked by NASA planners (see chart...
