...over sandbars waiting for landings. Tents, fires, laboring men spread along eight miles of riverbank. A trapper's wife opened a coffee shop in a tent. A clothing store sprang up in another. Old prospectors, panning methodically after thawing the frozen ground with fires, found traces of gold dust. But they found nothing else...
...Water. Nobel Prizewinner Harold C. Urey of the University of Chicago is one of the scientists who has arrived at a new theory of the earth's birth and development. According to Urey, the earth and the moon were formed at the same time out of the primeval dust cloud around the sun. First materials to "precipitate" from the cloud were light stony silicates, which formed the cores of the earth and moon. But the earth's core was bigger than the moon's, and it attracted much more of the heavy iron which precipitated later from...
...Dust to Dust. Long before Waksman began his work on soil, scientists had noted that if a diseased body is buried, the point of burial does not become a plague spot. Instead, something in the soil destroys the germs. It was proved that micro-organisms were doing the police job. But how, exactly, did one microorganism destroy another? By eating it? Beating it to the feed trough? Chemical warfare...
...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...
...first big chance came when Sears, Roebuck & Co. hired him in 1934 to dress up its Coldspot refrigerator, an ugly machine with a dust trap under its spindly legs, and corrugated shelves inside. Loewy moved the motor, from top to bottom, chopped off the legs, and installed the first non-rusting aluminum shelves ever to be used in a refrigerator. The Coldspot became a single smooth, gleaming unit of functional simplicity-and with it Sears' sales shot up five-fold by 1936. Loewy had been paid only $2,500 for the job (and had spent nearly three times that...
