According to his theory, this meant that the rock in its core was getting hotter and approaching the melting point. In December came the proof: the volcano had a small but definite eruption. In 1953 and 1954 the pattern was repeated. Whenever the volcano's magnetism diminished appreciably, a period of activity followed in two to six months. The greater the change in magnetism, the stronger the activity...
...final decisions are made, they are often hasty and ill-considered, based sometimes on factors as weak as personal bonds. The papier-mache treaty structure of the decade following the first world war and the conferences of the second, all the result of "high-level conversations," are indisputable proof of this handicap.

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...
