Then, says Urey, the light stone core began to float up through the iron like a tennis ball through molasses. As it approached the surface, land appeared for the first time; the oceans were crowded to one side, as on the third day of biblical creation.* For a while the earth had only a single continent (Pangea), but the continuing rise of the core material and its spreading out near the surface broke Pangea into chunks and carried them apart. His theory, says Urey, accounts for the remarkable fact, first pointed out by Alfred Wegener in his theory of continental...
Wealthy, 75-year-old Dr. Moniz, whose hands are badly deformed by long exposure to radioactivity, is the first Portuguese ever to win a Nobel Prize...
...Selman Waksman's "playing around with microbes" had paid off with one of the biggest jackpots that has ever gushed from a scientist's laboratory. Dr. Waksman (rhymes with boxman) had become the discoverer of streptomycin, which ranks next to penicillin among the antibiotics and is the first of these "wonder drugs" to show hopeful results in the treatment of tuberculosis...
...Waksman first thought of studying medicine, but Russia was not the place for him to do that. With four friends from Priluka, he decided to try his luck in the U.S. The young Ukrainians landed at Philadelphia in November 1910, and Waksman went to stay with a cousin, Molki Kornblatt, and her husband Mendel, on their five-acre farm in Metuchen, N.

Kornblatt gave him some advice which proved decisive: go to see Dr. Jacob Lipman, another Russian...
Gold Dust. In American Cyanamid Co.'s Lederle Laboratories at Pearl River, N.Y. another Streptomyces was found to secrete a gold-colored, germ-killing substance. Dr. Benjamin M. Duggar, the discoverer, called this antibiotic aureomycin. First used on human patients at New York's Harlem Hospital by Dr. Louis T. Wright, the "gold dust" worked wonders for victims of lymphogranuloma. Like Chloromycetin, it deals with many of the rickettsias. In treating brucellosis (undulant fever), aureomycin is likely to replace the streptomycin-sulfadiazine combination much used at present...
