today’s birthday: Ivan Pavlov (1849) Russian physiologist and Nobel laureate Ivan Pavlov is chiefly known for his discovery of the conditioned reflex, a reflex developed gradually by training in association with a specific repeated external stimulus. In the 1890s, he was investigating the gastric function of dogs when he noticed that the animals began salivating at the mere sound of the bell that preceded their feedings. He made this phenomenon the focus of his research. What other experimental subjects did he use in his research? More… Discuss

TODAY’S BIRTHDAY: GERTRUDE BELLE ELION (1918)


Gertrude Belle Elion (1918)

After teaching chemistry because jobs for female researchers were then scarce, Elion got work as an assistant at a drug company and went on to become a pioneering US pharmacologist. With George Hitchings, she developed treatments for leukemia, autoimmune disorders, urinary tract infections, gout, malaria, and viral herpes. Although Nobel Prizes are rarely awarded to drug company employees, the duo shared in the 1988 Nobel Prize in Physiology. To what did Elion attribute her interest in science? More… Discuss

Today’s Birthday: SIR FREDERICK GRANT BANTING (1891)


Sir Frederick Grant Banting (1891)

Banting was a Canadian physician who, with Scottish physiologist John Macleod, won a 1923 Nobel Prize for the discovery of the hormone insulin. Banting and his assistant Charles Best experimented on diabetic dogs, demonstrating that insulin lowered their blood sugar. Insulin was proven effective on humans within months of the first experiments with dogs. In acknowledgment of Best’s work, Banting gave him a share of his portion of the Nobel Prize. What tragic accident took Banting’s life in 1941? More… Discuss
