...good purpose--they give the whole story an aspect of abstraction which is effectively balanced by the warm and realistic sketching of his characters, largely through details of their conversion. Heliczer's strange form, in fact, seems almost necessary to counter the realistic detail of the young pedant, his acid girl, and their combined sensuality. Heliczer's narrative style is light and lucid, and his humor does not obstruct the seriousness of the piece as a whole...
President Eisenhower had called this second meeting of Geneva "the acid test" of whether the spirit of Geneva marks a genuine change on the part of the Russians. But the Russians had all but declared in advance that they had no intention of settling anything at the second Geneva meeting. They had got what they wanted at the first Summit meeting-a finding, brought in not by the statesmen but by the public, that the world did not stand in danger of war. In effect, they had got "peace" merely by declaring it. They felt no need or compulsion...
...Continental Support. This week Secretary Dulles went back to Geneva for a conference of the Big Four foreign ministers, which President Eisenhower had defined as "the acid test" of the Soviet Union's peaceful intentions. After conferring last week with the President in his hospital room at Denver, Dulles reported: "I go to Geneva with the assurance that I have behind me a President who fully knows the issues and who has given me a full and comprehensive mandate to speak for our nation." He also got assurances of support from the leaders of Congress...
Degraded Virus. The two researchers worked with the simple and well-known virus that causes mosaic disease in tobacco plants and is called TMV for short. Its particles are rod-shaped, and are known to consist of central cores of nucleic acid with protein molecules strung around them. Drs. Fraenkel-Conrat and Williams prepared pure solutions of the submicroscopic rods, mixed them with dilute alkaline chemicals and held them close to the freezing point for two to three days. This treatment "degraded" some of the virus, separating the rods into nucleic acid and protein molecules. Undegraded rods were taken...
...Fraenkel-Conrat and Williams then mixed the two parts of the virus together, made the solution slightly acid and held it just above freezing point for 24 hours. At the end of this period, the protein molecules had rearranged themselves on the nucleic acid cores. When tested on tobacco plants, the virus proved infectious. It grew and multiplied in the green leaves, producing the characteristic spots of tobacco mosaic disease...
