Prime advocate of the theory that living creatures are no more than highly coordinated systems of chemical and physical reactions was German-born Biologist Jacques Loeb. In 1899, by fertilizing sea-urchin eggs with chemicals and producing young larvae, he struck a heavy blow at the popular vitalistic theory which maintained that some intangible "vital spirit" or "entelechy" was necessary to life. Sixteen years later, he grew healthy tadpoles from frog eggs fertilized by a needle prick, showed his scientific opponents that no vital spirit from a male frog was necessary for creation of new life...
...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...

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...
