...result there are three Communisms in the world today. The virulent Chinese variety would infect the world with "wars of national liberation." The Russian brand has graduated from the minor leagues of guerrilla warfare, and wields vast military and economic power in hopes of winning the world to Marxism through example. The Red states of Eastern Europe have developed a milder, more "relaxed" strain, one better suited to their lack of economic and military muscle. Fragmented by history and welded by ideology, they have arrived at an almost dialectical synthesis of the tensions tearing at them: nationalist, neutralist Communism...
...latter conference of educators and Peace Corps staff, the constantly recurring theme was the inability and unwillingness of almost all universities to respond to the Peace Corps.

Though injections of killed bacilli, as in the vaccines now generally used, stimulate the production of antibody in the blood, they seem to have little effect on multiplication of bacilli in the small bowel, where they do their damage before being excreted to infect a new host. Dr. Mukerjee is working on a vaccine made from live but harm less varieties of El Tor, which would be taken by mouth and would, he believes, protect the bowel...
Just about everyone and, inevitably, his brother has had athlete's foot. The various fungi which masquerade under that name annually infect an estimated 40 million people in the U.S., 2,000,000 of them badly enough to send them sprinting to a doctor. But until recently, doctors could recommend little more than the various medications available without prescription on drugstore counters.

With Stand-ins. To check and expand on these hypotheses, Lwoff chose to work with single-celled organisms, such as bacteria, because they have a single chromosome (whereas man has 46). As stand-ins for genes he chose viruses that infect bacteria (bacterio-phages), because their cores consist of nucleic acid. What actually happens Lwoff found, is not as simple as had been thought. The viral nucleic acid, in effect masquerading as a gene, might do one of two things after invading a bacterium: 1) stimulate the bacterial cell to produce hundreds of copies of the virus particle, and destroy...
