Freedom from Pain. Recent burn therapy has been so unsatisfactory that Dr. Moyer and Dr. William Monafo were seeking some agent to act as a barrier against the invasion of burned skin by bacteria. Silver nitrate, they knew, would do the job, but in the 5% to 10% concentrations formerly used, it would also burn healthy skin. They wondered whether a weaker solution would work. At 1%, it worked but it still burned skin. Without much hope of success they switched to the greater dilution...
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...
...Bacteria normally multiply by sexless fission-they simply split in two. Still, scientists believe that some kinds of bacteria occasionally manage a kind of sexual mating. It is almost impossible to catch them in the act, though, because they have no special sex organs, and often when they cling together it is not for love. But at least one kind of microscopic bug has a sex life with a difference. Professors Pavel Nemec and Vojtech Bystricky of the Slovak Polytechnical University in Bratislava report that the Caulobacter, a harmless bacterium found in soil, possesses a multi-purpose organ that...
...Mars & Venus. Westinghouse produces salt-water-conversion plants that can make 50 million gallons of fresh water a day and bacteria-killing bulbs that give no light the human eye can see, is also working on a nuclear engine that may some day power spaceships to Mars and Venus. Under Burnham, its money-losing heavy-electrical-equipment division is again profitable (thanks in part to price boosts), and its long-neglected consumer division will finish 1964 in the black ("but not by very much," says Burnham) for the first time in several years. Westinghouse has developed dozens of new consumer...
