War production suggestions. For making a contribution that will safeguard lives of combat pilots, James A. Merrill, research chemist at Goodyear Tire and Rubber Company, Akron, Ohio, was presented with a Citation of Individual Production Merit by War Production headquarters of the War Production Board (WPB). His suggestion concerned development of a resistant barrier to aromatic fuels used in bullet seal tanks on airplanes. It will help keep planes in the air under extreme weather conditions, save the lives of pilots returning in planes with gas tanks pierced by bullets, and lessen unnecessary plane crashes

Easter bunnies' laurels threatened. Government experts enable hens to color own eggs. Washington, D.C., April 7. An interesting experiment is in progress at the National Agricultural Center, Beltsville, Maryland, whereby hens color their own eggs over a range of hues from a pearly white through brown to sky-blue. This picture of Charles A. Denton, Junior Chemist, at the nutrition laboratory, shows the method of measuring the yolk index. Eventually we may anticipate a uniformity of eggs in shape and in yolk color as well as a definite amount of proteins contained in each one. 4.7.39
