...speeded up enormously. Up to 1947 only 60 viruses had been listed as causing disease in man, and a mere 20 of these singled out the human species as their prime prey. The rest, like the one that causes eastern equine encephalitis (TIME, Oct. 5), normally attack lower animals, infect man accidentally, said Dr. Schuman...
...Stewart-Eddy) polyoma (multiple-tumor) virus has hurdled the species barrier and caused cancers not only in mice but in rats and in Syrian and Chinese hamsters. In rabbits, for some strange reason, it causes only benign tumors. So far, Drs. Stewart and Eddy have not been able to infect monkeys with their virus, but a determined effort to do so is under way at Roswell Park Institute. Patricia, a lone baby monkey harboring polyoma virus, has her own spotless nursery where she is cared for by Nurse Althea Higgins. Drs. Stewart and Eddy have gone a vital step farther...
Kopit has an unusual talent for working hard and getting things done. One suspects he must write swiftly because one reads him swiftly. One imagines he spends his time thinking out what he will write, because he avoids the confusion and inconsistency that often infect work by young writers...
Apart from its mission of feeding facts to farmers, the Journal is a tireless, effective crusader on issues great and small. In 1953, within six months after the magazine had demanded, "Let's Make 'Em Cook Raw Garbage" (to kill the vesicular exanthema virus that can infect hogs), 28 states enacted appropriate laws. Currently, Editor Streeter is busily engaged in a crusade in which the stakes are no less than the future of the American farmer, afflicted as he is by a self-defeating Government program that this fiscal year is costing the U.S. taxpayer a scandalous...
...important was Lederberg's later discovery that viruses preying on bacteria can change the heredity of their victims. In this process, which is called transduction, a virus invades a bacterium, breaks it up and reorganizes its material into hundreds of new virus particles. If these particles in turn infect another bacterium and it survives, they sometimes change it into a new strain. Apparently the viruses, acting somewhat like submicroscopic spermatozoa, take hereditary material from the first bacterium and transfer it to the second...
