...short answer is that they have wrought no miracles. Atomic medicine has cured no disease that cannot be cured without it. But in five years there has been time to explore only a fraction of the new frontier-and meanwhile there have come discoveries in three directions that are worth cheering about...
...recognize her family. Into her bloodstream the doctors injected a solution containing boron, a common, stable element with an atomic weight of 10. But under neutron bombardment, boron-10 changes to an excited boron-11, which lives about one-hundredth of a trillionth of a second. In that infinitesimal fraction of time before it decays to stable lithium, it shoots out alpha particles...
...second appeal is to the "tremendously fertile and socially significant fraction of young men and women in our universities." He says that "it is among these fresh and precious souls, well lubricated, enflamed and integrated with beer, romantic love and lusty singing that this allegory will find its most fertile soil...
...Point Four funds were obviously closest to Harry Truman's heart. "Stomach Communism," he observed, "cannot be halted with weapons of war ... It is only a fraction of the amount I have asked for military purposes, but who can say that in the long run it may not have a greater effect?"

Cohn was asked to investigate to determine whether animal plasma could be safe for human transfusion. New methods for the fraction of plasma were therefore rapidly developed during the spring and summer of 1940. Techniques to yield undenatured products of great stability resulted. These methods had been applied successfully on a large scale, and studies were available demonstrating the value of such products in the treatment of shock...
