This foster mother had been injected with a crude extract from pituitary glands. In 1932 Dr. Oscar Riddle and his associates at the Carnegie Institution's station for experimental evolution on Long Island obtained in almost pure form the same pituitary substance which had made Ehrhardt's monkey act like a mother. Because it was a stimulant of milk secretion this substance was called prolactin...
With the amused impatience of a godless materialist. Soviet Scientist Oparin waves away the various vitalistic theories which hold that life appeared because of some transcendent animating principle which pervades the universe-or that life has always existed.

At the University of Rochester a promising, extravagantly polite young scientist named John Warkentin is investigating animal eyesight with a more efficient technique which requires no training, last week made public some of his findings...

Two famed fossils of which much has been made are Peking man or Sinanthropus, found in the caves at Choukoutien about a decade ago by a Chinese scientist named Pei Wen-chung; and the Java apeman, Pithecanthropus erectus, discovered on the banks of Java's Bengaman River in 1892, by Dutch Anthropologist Eugene Dubois. Both of these oldsters appear to have lived at the beginning of the Glacial Period-roughly 1,000,000 years...
