...Federal bugmen in New Jersey have loosed swarms of another wasp, Tiphia, together with a bacterium, against the Japanese beetle (TIME, April...
...than they think of amebae, clams and sponges as "animals." But practically all biologists class bacteria as plants. Some plants can be patented. Last week Technology Review, M. I. T.'s bouncing monthly magazine, had itself a chuckle as it told of a recent attempt to patent a bacterium...
...Dubos first found a soil bacterium that is bad news for pneumococcus, the pneumonia germ. The bacterium secretes an enzyme that dissolves the germ's tough outer covering or capsule, and the stripped pneumococcus is then easy prey for the body's natural defenses, as experiments with living mice showed...
Mice & Men. Leukemia is a blood disease in which white blood cells proliferate wildly, invade organs and tissues. At the Department of Genetics, Dr. Edwin Carleton MacDowell and his co-workers found that leukemia is not transmitted by a bacterium or virus, that it is a malignant disorder resembling cancer. Moreover, they discovered that some mice could be made immune by shooting into them leukemic cells inactivated by mild heat (115° F.). So far, this work has not produced a cure for leukemia in man, but may lead to one eventually...
...fever, certain tumors, common colds. At Princeton Dr. Stanley grew acres of tobacco plants, infected them with the disease known as tobacco mosaic, ground up their wizened leaves, extracted their juices. This liquid was highly infectious to normal plants. But the deadly principle could not be cultured like a bacterium. Dr. Stanley found that it could be digested - that is, destroyed - by certain enzymes such as pepsin. This was important. Pepsin digests only proteins. Finally, using an ammonium compound which nudges proteins out of solution, Dr. Stanley isolated the virus as white crystals. When diluted 100,000,000 times...
