Nebraska Farm Boy. These basic facts of genetics were becoming known about the time Geneticist George Beadle was born in 1903. His father ran a small, progressive farm near Wahoo, Neb. (1900 pop. 900). His mother died when he was four, leaving him, his brother and sister to be mothered, after a fashion, by a succession of hired housekeepers. He remembers farm life in general with pleasure, but he still dislikes cream because he had to skim it off endless milk pans...
When Muller made this discovery, he may have heard a roll of distant thunder, but he could not have known what it meant. In the year 1926, long before Hiroshima, no man-made radioactivity was at large on earth outside the range of X-ray machines and radium capsules, and none was expected. No one suspected that in less than 20 years the mutation-producing effects of radiation would be a worldwide worry...
...long-range scientific results. The success with Neurospora yielded new techniques for using molds and other small organisms as genetic tools. Out of its use flowed a new attitude toward genetics. No longer were genes considered abstract units of heredity. They became actual things, not entirely understood but known to be concerned with definite chemical actions. Professor Joshua Lederberg, 33, of the University of Wisconsin, probably the world's leading young geneticist, says that the Neurospora work at Stanford clinched the whole idea that genes control enzymes, and enzymes control the chemistry of life...
...symbol DNA, which stands for deoxyribonucleic acid. It is a giant molecule of slightly variable composition that is found in chromosomes, and it is believed to be the substance that determines heredity and governs all cells (and therefore all life) from the stronghold of the nucleus. DNA has been known to exist for years, but until postwar years little was known about it. Now it is being attacked from many angles by nearly every breed of scientist...
Bible Quiz. That was two years ago. Since then, Sant'Angelo in Villa has known little peace. Three parish priests came and went, and half the villagers boycotted the church. One day a young (33), eloquent Baptist minister came to the village, was challenged by a priest (and locally famed Bible expert) to a Bible quiz in Latin and Greek. After four hours and 45 minutes, the Baptist came out the popular victor. Encouraged by his success, Pastor Graziano Cannito began to hold services in a private house, soon chalked up 70 Sant'Angelo conversions. In nearby towns...
