...James Franklin Yeager of the Department of Agriculture projected on a screen a cardiogram from the beating heart of a cockroach. This was obtained by exposing the heart of the insect and placing on it a minute drop of wax. A human hair inserted in the wax was connected through a lever to a fine wire. The heart beats thus jerked the wire and a light beam passing across it translated them into a pulsating graph. The Department uses this method to study the cardiac effect of insecticides...

It occurred to shy, elderly Miss Griswold, as to many another investigator, that the dryness of U. S. homes in winter may be what deters moths' winter activities. If this is so, she reasoned, the blessing of air-conditioning would also be a blessing for moths. Miss Griswold and a young associate named Mary Frances Crowell rigged a number of jars in which five different humidities, ranging from...
