...noblest impulses are apt to offend against nature. While improved medical care assures the survival and reproduction of those with genetically caused mental and physical defects, it also ensures that an increasingly larger percentage of the population will be heir to these illnesses in years to come. Geneticist Theodosius Dobzhansky succinctly expresses the ethical dilemma. "If we enable the weak and the deformed to live and to propagate their kind," he says, "we face the prospect of a genetic twilight. But if we let them die or suffer when we can save or help them, we face the certainty...
...years later, the suspicions were dramatically confirmed by the pioneering geneticist Thomas Hunt Morgan in Columbia University's famed "Fly Room." Through ingenious crossbreeding experiments with the fruit fly Drosophila melanogaster, Morgan and his students were able to map the relative positions of the genes along the insect's four pairs of chromosomes. Still, the gene's physical nature remained as great a mystery as ever. DNA had been discovered in the nuclei of cells by the Swiss biochemist Friedrich Miescher a few years after Mendel did his work on peas. But since the chromosomes in which...
...leaving the vast majority of Soviet citizens untouched, but the identity of the protesters is significant. They include not only famed artists like Nobel Prizewinning Novelist Alexander Solzhenitsyn and Cellist Mstislav Rostropovich but also scientists such as Andrei Sakharov, father of the Soviet H-bomb, Physicist Pyotr Kapitsa and Geneticist Zhores Medvedev. A mimeographed bimonthly chronicle of dissident events circulates among thousands, perhaps tens of thousands...
...already terrorized London, Dr. Vannevar Bush, head of the Office of Scientific Research and Development, said that intercontinental missiles would not be possible for a "very long period of time." The American public, he impatiently contended, should not even think about them. Only last December, Dr. Bentley Glass, a geneticist and the retiring president of the American Association for the Advancement of Science, added his name to the list of doubters. The basic laws of science are all now known, he said. "For all time to come these [laws] have been discovered, here and now, in our own lifetime...
After all of mankind's headlong progress of the past century, science may well have reached its limit for discovery. This startling thought was offered last week by Geneticist Bentley Glass in his valedictory as president of the American Association for the Advancement of Science. "The laws of life," he said, "are based on similarities, finite in number and comprehensible to us in the main now. For all time to come, these have been discovered, here and now, in our own lifetime...
