Recently Added Features
During the 1920ís at the University of Texas in Austin, Hermann J. Muller showed that exposure to radiation changed the genetic makeup of fruit flies (Drosophila). For this discovery, he received the 1946 Nobel Prize in Physiology or Medicine. From 1945 to 1964 Muller was at Indiana University in Bloomington. During this time he received support from the Atomic Energy Commission (AEC) for continued research about radiation altering the incidence of mutations in Drosophila. [added 1/2015]
In 1932, Carl David Anderson discovered the positron, a positive charged electron, and confirmed Dirac’s concept of matter and antimatter. This discovery took place in a cloud chamber surrounded by an electromagnet that was designed and built by Anderson. For his discovery, Anderson received the 1936 Nobel Prize in Physics.

While at Stanford, Robert Hofstadter conducted research about elastic and inelastic scattering of high energy electrons by atomic nuclei. He showed that the proton and the neutron were non-point particles and therefore possessed structure. Hofstadter was awarded the 1961 Nobel Prize in Physics for this work. [added 8/2014]
