...feeding plants with radioactive elements, California botanists have found to their surprise that plants can assimilate food downward as well as upward. More surprising was their discovery that "if barley plants are exposed to radio-nitrogen, a small quantity of labeled nitrogen compounds are formed in the tissues of the plants." This may well show, says Hamilton, that leguminous plants (clover, peas, etc.) are not unique in their power to fix atmospheric nitrogen...
Bacteriophage is almost as elusive as filtrable viruses; it can scarcely be seen under a high-powered microscope, and must be cultured on a special nitrogen compound called asparagine. For every patient, said Dr. MacNeal, he must send a sample of blood or pus containing the bacteria to special laboratories, have the bacteriophage made to order. It is injected into the veins, as much as a quart in eight hours. Since it is difficult to culture, doctors seldom think of using it until the "extreme stage" of illness. According to Dr. MacNeal, bacteriophage first weakens bacteria with special enzymes, then...
...rats, mice and rabbits in their research work. When they gave the animals huge doses of sulfa drugs, or of common poisons, the scientists found that five basic substances present in normal blood promptly dwindled or disappeared. The vital chemicals: 1) ascorbic acid (vitamin C); 2) choline, a nitrogen compound, a constituent of nerve tissue; 3) cystine, a sulfur-containing compound found in hair and finger nails; 4) glycine, a protein derivative found in bile; 5) glucuronic acid, an organic acid found in urine...
...there are two types of fungi: 1) parasites, which feed on living plants and animals; 2) saprophytes, which feed on dead organisms. Pleasant are some fungi, such as the mushrooms (commercially grown on horse manure) which decorate steaks. Valuable are others, like the bacteria which decompose dead organisms, fix nitrogen in the soil, promote fermentation.* Harmful to man are fungi which attack crops...
...Knut Toring chucked his job, left his wife and children, went back to live in his native village. With overalled Betty Eskilsson, who announced that she had renounced the old trinity for a new one-nitrogen, calcium and superphosphate-Knut formed the Young People's Society to keep peasant boys on the farm through cooperatives and communal culture. World War II was on the way before the Young People's Society got its community clubhouse started, but the book ends with them digging away - a symbol of what Author Moberg thinks the post war world should look like...
