...less fantastic than this lore from Pliny's Natural History* was the fertilization of rabbits reported before the sober American Philosophical Society last week. Not the wind but simply cold, applied by ice packs to the bellies of doe rabbits, made them pregnant, reported Physiologist Herbert Shapiro of Philadelphia's Hahnemann Medical College...
Getting Used to It. Men can adjust themselves to Antarctic living, but their bodies acquire a new balance, reported Physiologist Ernest E. Lockhart. The repeated stimulus of low temperatures makes blood pressure increase by 25 to 35% and makes the rates of respiration and heart-beat decrease somewhat. Basal metabolism is about 10 to 15% lower than in temperate climates. These reactions were unexpected, for they do not occur among Eskimos...
...plants bloom faster when their flowers are picked? The dominant bud, explained Plant Physiologist John William Mitchell of the U.S. Department of Agriculture, apparently produces a hormone which inhibits growth of the other buds on the same stem. If it is snipped off, the uninhibited buds can burst into bloom...
Motherless Frogs. Five years ago Physiologist Gregory Goodwin Pincus of Clark University produced fatherless rabbits by removing ova from virgin females, fertilizing the ova with a salt solution, replanting the fertilized eggs in other females to gestate (TIME, April 6, 1936). Last week Dr. Keith Roberts Porter of the Rockefeller Institute announced that he had produced a greater wonder: motherless tadpoles. He removed the nucleus from a frog's egg at the moment of fertilization, but before it could unite with the nucleus of the male sperm. This made the mother's contribution apparently a mere anonymous drop...
...possible cure for stomach ulcers was last week announced by an eminent physiologist, Andrew Conway Ivy of Northwestern University. Most doctors hold that ulcers are caused by an overactive stomach, which constantly gushes acid, erodes its own walls. For years Dr. Ivy has tried to curb this acid formation. To the members of the American Physiological Society meeting in Chicago last week he described a hormone which seems to turn the trick: enterogastrone, extracted from hog intestines...
