...found in wheat germ oil, lettuce and tomato oils. Certain it is that lack of this vitamin, as well as vitamin A, damages male reproductive tissues, produces abortion in the female. Although large doses of wheat germ oil have proved effective in stopping habitual abortion in pregnant women, Chemist Henry Albright Mattill, University of Iowa, cautiously concludes that, until more evidence is available, "attempts to produce a market for wheat germ oil among prospective parents generally are to be deprecated...

Atoms of the same chemical element which have different weights are called isotopes. Isotopes are Chemist Urey's special ty. He won a Nobel Prize for discovering deuterium, the heavy isotope of hydrogen which makes "heavy water" (TIME, Nov. 26, 1934). Later, one of the Urey crews produced large quantities of heavy nitrogen (TIME, Sept. 20, 1937). Nitrogen is present in all proteins. Heavy nitrogen atoms can be distinguished from the common kind by mass spectrographic means, but in protein reactions they run along with their lighter fellows, and so serve as "tagged atoms" or chemical spies to show...

...from the molecules and formed new compounds at random-in quantities predictable by the laws of chance. For this reason, popularized versions of the Calingaert research referred to it as a chemical "dice game" or "poker game." Actually, since he deals with trillions of molecules in one operation, the chemist always knows what sort of hand he will draw...

...Chemist Calingaert predicted that U. S. industry would lose little time applying his discovery to a variety of chemical shortcuts. Last week Ethyl Gasoline's alert Vice President, Thomas Midgley Jr., compared the Calingaert discovery to a ferryboat which enabled loving but frustrated lads and lassies on opposite sides of a river to get together. "What a lot of fun we're going to have," said Mr. Midgley, "shoving that ferryboat around...

...resource-poor nations like Germany and Italy, a large part of war science is concerned with the invention and manufacture of Ersatz or substitute foods and synthetic materials. Germany's brilliant chemist, Friedrich Bergius, 54, who a quarter-century ago conceived the hydrogenation process for making gasoline from coal, is likely to be one of the most useful men in warring Germany, and one of the most hated by those who have to eat his Ersatz foods. From sawdust Bergius has extracted a digestible sugar, equal in food value to barley. Of the sawdust 60% to 65% becomes sugar...
