...Stanley thinks that the techniques used by Tsugita and Fraenkel-Conrat may be developed to the point of proving "a Rosetta Stone for the language of life.'' If applied to many mutant viruses, they may break entire genetic codes, telling which groups of bases are responsible for what characteristics. The next step, perhaps years away, will be to do the same with the more complicated molecules of DNA that govern the heredity of higher animals. At some point during this effort...
Deaths from influenza and bacterial pneumonia (hard to separate, because one so often complicates the other) were about 50% above average for January's first half, reported the U.S. Communicable Disease Center. In seven states and the District of Columbia the active flu virus was identified as the mutant Asian strain, A2-57. In seven other states the same strain was suspect, but not yet convicted on laboratory evidence...
...three children so afflicted-which may be the most important clue yet to endocardial fibro-elastosis. One theory so far: it begins developing in the fetus, though nobody knows why. The Singer family recurrence, says Dr. Bernard M. Wagner, a top Seattle heart specialist, "suggests lethal genes, a genetic mutant. This may be a key family in our study." For the stricken Singers last week, it was little comfort, but all they...
Poorer Progeny. Much less uncertain are genetic effects. Said the report: "Exposure of gonads to even the smallest doses of ionizing radiations can give rise to mutant genes which accumulate, are transmissible to the progeny, and are considered to be, in general, harmful to the human race." Doubling the present human mutation rate would probably not lead to the race's extinction. But the scientists felt little doubt that any increase at all will lower the average of human intelligence and life expectancy...
