Garbled Message. Dr. Fogh's most provocative finding: when PPLO infect human cells grown in test tubes, they destroy some cells, but-more significantly-alter the genetic material of others. They cause the development of deformed chromosomes, and even of entirely new chromosomes never seen in natural cells. Thus, their presence gives the cell a garbled genetic message so that it will produce abnormal daughter cells-a process sometimes observed in cancer. Neither Dr. Fogh nor anyone else is yet ready to say flatly that PPLO cause cancer, but since researchers have found the organisms in test-tube growths...
...appears that a good way to do it is to fight staph with staph. There are as many varieties of staph as there are breeds of dogs, and some are harmless while others are vicious. Researchers in Manhattan and Cincinnati got the idea that if they could "infect" newborn babies with a harmless strain, these germs might somehow prevent later invasion by dangerous strains...
Though Dr. Uhr has worked with some viruses that infect man, most of his experiments have been with the tiny ΦX174, which normally attacks only bacteria. It may seem a long leap to any useful application in human medicine, but Immunologist Uhr, who is now director of the Irvington House Institute for Rheumatic Fever and Allied Diseases, has already shown that newborn babies react to ΦX in much the same way as guinea pigs. And children's reactions to antigens are immensely important in rheumatic fever, which seems to result from the body's mistaking part...
California virologists: Italian-born Dr. Renato Dulbecco, 50, now at the Salk Institute for Biological Studies in San Diego, and Dr. (of veterinary medicine) Harry Rubin, 38, of the University of California. Starting with viruses that infect bacteria, Dr. Dulbecco went on to show the mechanism by which polyoma virus, which causes many animal cancers, infects cells. Most important was the striking and unexpected finding that the virus itself, which has a nucleus of deoxyribonucleic acid (DNA), does not need to multiply in order to cause cancer...
...thesis that "the purpose of great art is a moral one" and came out for "the old lesson which Beauty has taught for so many years, the lesson of goodness and kindness and strength which has caused poets to identify it with truth." He deplored "the diseases which infect the world of painting today-of obscurity, confusion, immorality, violence" and said that "one of the prime requisites of greatness in art is to be easily understood." To Hartford's critics, these goals spell sentimentality and escapism, not "Things as They are," although the history of art is full...
