Life
Rosalyn Yalow was a stubborn and
single-minded child. Her parents wanted her to become a schoolmistress, but
instead they became a physicist who was awarded the Nobel Prize in Physiology
or Medicine. Rosalyn Yalow grew up in and lived almost her entire life in New
York. Her parents came from humble backgrounds, but that did not stop Rosalyn
and her brother, Alexander, from striving for something greater. Rosalyn began
to read before she began preschool. Her 7th-grade chemistry teacher aroused her
interest in science, and when at university, she took a liking to nuclear
physics. Rosalyn Yalow was married with two children.
Work
Rosalyn Yalow was a nuclear
physicist. She developed radioimmunoassay (RIA) together with doctor Solomon
Berson. RIA is used to measure small concentrations of substances in the body,
such as hormones in the blood. Rosalyn Yalow and Solomon Berson tracked insulin
by injecting radioactive iodine into patients' blood. Because the method is so
precise, they were able to prove that type 2 diabetes is caused by the body's
inefficient use of insulin. Previously it was thought that the disease was
caused by a lack of insulin.

Rosalyn S. Yalow
(From Encyclopædia Britannica)
With a colleague, the American physician Solomon A. Berson, Yalow began using radioactive isotopes to examine and diagnose various disease conditions. Yalow and Berson’s investigations into the mechanism underlying type II diabetes led to their development of RIA. In the 1950s it was known that individuals treated with injections of animal insulin developed resistance to the hormone and so required greater amounts of it to offset the effects of the disease; however, a satisfactory explanation for this phenomenon had not been put forth. Yalow and Berson theorized that the foreign insulin stimulated the production of antibodies, which became bound to the insulin and prevented the hormone from entering cells and carrying out its function of metabolizing glucose. In order to prove their hypothesis to a skeptical scientific community, the researchers combined techniques from immunology and radioisotope tracing to measure minute amounts of these antibodies, and the RIA was born. It was soon apparent that this method could be used to measure hundreds of other biologically active substances, such as viruses, drugs, and other proteins. This made possible such practical applications as the screening of blood in blood banks for hepatitis virus and the determination of effective dosage levels of drugs and antibiotics.
In 1970 Yalow was appointed chief of the laboratory later renamed the Nuclear Medical Service at the Veterans Administration Hospital. In 1976 she was the first female recipient of the Albert Lasker Basic Medical Research Award. Yalow became a distinguished professor at large at the Albert Einstein College of Medicine at Yeshiva University in 1979 and left in 1985 to accept the position of Solomon A. Berson Distinguished Professor at Large at the Mount Sinai School of Medicine. She was awarded the National Medal of Science in 1988.
