...Nobel Prize for discovering the positron. Meanwhile, Caltech biologists have been probing their own areas of the invisible. Geneticist Alfred H. Sturtevant described the linear order of genes; Calvin B. Bridges provided proof for the chromosome theory of heredity. In determining that genes control the synthesis of vitamins and amino acids, George Beadle discovered the bread mold, Neurospora, as an effective research tool. This has sped the progress of genetics a hundredfold, was partly responsible for the successful increased production of penicillin...

Also, he has had a break because his rice dishes prepared in the center's elaborate metabolic kitchens have included such delicacies as olives, mushrooms and an apple pie (made with a rice crust...
