...1880s, Alfred Russell' Wallace, great British biologist who originated independently the theory of natural selection at the same time as Charles Darwin, visited the U. S. He lectured at a small agricultural college in Kansas, stayed at the house of the college president. One student who listened to him with particularly wide-eyed wonder was the president's son, David Fairchild, who had already resolved to be a botanist, was studying parasitic fungi and the wind-borne movements of Kansas tumbleweed...
Lancelot Hogben is a blue-eyed, tousel-haired British biologist of 42 who once occupied a chair of Social Biology at the University of London, and who has educated himself in many fields of science...
Even schoolboys know that birds mate in the spring, but even a bright schoolboy could hardly tell why. Biologist James C. Perry of Cincinnati's Xavier University, no schoolboy by a long shot, was convinced last week that it is not so much the flowers that bloom in the spring as what birds eat that affects their mating cycle. Other investigators had advanced the theory that increased exposure to sunlight in the spring is the sex stimulus. This theory they checked experimentally by inducing sex gland activity with artificial illumination. It looked as if the light stimulated the front...
...Yale University's Medical School, two years ago, Biologist Leonell Clarence Strong fed oil of wintergreen to laboratory mice with cancerous tumors of the breast. Some of the tumors melted away. The thing that did the trick was the active principle of wintergreen oil, heptyl aldehyde, a fragrant, colorless liquid. With the help of his colleague, Leon Fradley Whitney, Dr. Strong then set to work on dogs. In last week's Science the biologists revealed the following promising results: injection of small amounts of fresh heptyl aldehyde under the skin of ten dogs with various types of spontaneous...
...California's Stanford University last week Biologist Dietrich Bodenstein displayed a winged insect which was half immature pupa, half mature butterfly. This monster was a by-product of Dr. Bodenstein's discovery of the agency which causes the final metamorphosis from pupa to adult. It is a growth substance generated in the head which reaches the tissues through the skin. It may be a hormone, but since hormones have not previously been found in insects it may also be an enzyme or some sort of nerve stimulus...
