...Rose bred his rats from a group originally purchased ten years ago. Most U. S. white rat experimenters, however, get their supply from the Wistar Institute of Anatomy and Biology at University of Pennsylvania. There in specially built steel and concrete buildings, under the watchful eye of Dr. Henry Herbert Donaldson, world authority on Mus Norvegicus albinus, hordes of white rats are fed and pampered as carefully as princelings. For 96 generations the rats have breathed only pure and sterile air. Visitors who might bring in germs are shooed off. Eventually it is hoped that the animals will be wholly...
...creosoting ties for U. S. railroads. Both Eastern Gas and Koppers Gas grew out of a patented coke oven invented by a German named Heinrich Koppers, who improved the method of saving the gas and other coal derivatives formerly blown away in thick smoke. His process caught the eye of Pittsburgh's late Henry Bedinger Rust, who took his ideas for exploiting the Koppers patents to the Mellon family offices...
...near-sighted eyes of posterity, historical figures are apt to loom larger and more beautiful than they do under the historian's microscope. To every true-blue Briton, Horatio Nelson was one of England's greatest heroes, and his beauteous Lady Hamilton the fitting Venus to his Mars. But not to the microscopic eye of Biographer Marjorie Bowen* whose tale is enough to turn a true-blue Briton purple or green, set Nelson himself whirling on his Trafalgar column...
Vitamin A, of which he was one of the discoverers, received his specific denunciation. It does help the body of children to grow. It does help prevent eye diseases. But, said Dr. McCollum, Vitamin A does not directly prevent colds as many manufacturers of candies and drugs claim. The only effect Vitamin A has on colds is to increase secretions from mucous membranes of nose and throat. Those secretions kill invading germs, may prevent a cold, if germs actually cause colds. His advice was not to drink cod-liver oil, in which Vitamin A is usually sold, as a cold...
Last January it struck a photographic plate under Mt. Wilson's 100-inch telescope, where its record was observed by famed Edwin Powell Hubble. Because of its great distance the star never approached naked-eye visibility, faded rapidly in late February. But Dr. Hubble's coworker, Dr. Milton LaSalle Humason, took spectroscopic and photometric observations which indicated that at the peak of its long-ago death agony the super-nova was 50 times as hot and 10,000,000 times as bright...
