Little sound waves are deadlier than big ones. Last week the U.S. Army Signal Corps described (with dark reticence) some experiments at State College, Pa. on sound waves too short (high-pitched) for the human ear to hear. The inaudible racket killed mice in one minute. The insidious little waves also killed cockroaches and mosquitoes...
...Signal Corps did not describe the gadget used to generate the waves. Neither did it tell the military objective of the experiments. The Germans tried with no success to use sound as a military weapon in World War II, but their devices were comparatively crude. The Signal Corps may see some possibility of killing not only mice...
Feet First. Rebecca had not been in London long before she sat at the feet (a vantage point of signal value) of practically everybody worth observing. Her great friend, Novelist G. B. Stern, with whom Rebecca shared meager quarters in those pioneer days, would be struck speechless by the arrival of successive literary lions with whom Miss West would chat, easily and informally, about the private lives and feuds of the legendary characters then dominating the British literary scene...
...smell receptors," patches of specialized cells in the upper nose, lie across air passages from tissues which are normally cooler than they are. Therefore the cells radiate heat waves across the air stream. Beck & Miles theorized that when pure air is passing through the nostrils, the cells give no signal; they are getting rid of their heat at the standard rate. But when an odorous vapor is present in the air stream it absorbs certain wavelengths of the heat which the cells are radiating. The cells can feel the change and the stimulus produces a sensation of smell...
High prices have hit the hospitals such a staggering blow that many may have to close their doors in 1948. That "storm signal of approaching disaster" was announced last week by leaders of Manhattan's United Hospital Fund, who are waging a desperate campaign to save New York City's voluntary hospitals from financial collapse...
