...destruction took 40 minutes. With the help of Mary Peshlakai, a Navajo squaw who had come with them from Window Rock, Ariz, to weave blankets for the Museum's Indian exhibit, Charley and the Short Man's Grandson muttered, groaned, sprinkled corn pollen over the figures they had painted. Then they stood to one side and chanted. It was not funny. It was moving. Still chanting, Charley carefully shuffled over the design, destroying it section by section. When the sand painting was obliterated, Charley Turquoise pronounced a solemn blessing on all those present, prayed that...
...first step is to find out what a patient is allergic to, by means of skin tests which result in small reactions to the offending substance. If it is a food or something similar, all the patient has to do is avoid it. If it is a wind-borne pollen that cannot be escaped, the patient may try "desensitization" treatment, which involves injecting very small quantities of the allergenic protein. How or why desensitization works is unknown. The benefits of desensitization are temporary and partial, though the degree of relief may seem wonderful to a sufferer. Treatments must be repeated...
...reproduces by means of male sperm and female eggs. The sperm is produced and dispersed from the tassels at the top of the stalk; the eggs lurk at the base of the silk on each ear. In ordinary "open-pollinated" corn, fertilization occurs at random, the sperm-bearing pollen being carried to the silk by the wind. For inbreeding, the tassels and silk are protected by paper bags until maturity, and the plants are then self-pollinated by hand. These inbred strains become highly uniform. Finally, promising strains are crossed to combine advantages-long ears, full-kerneled ears, resistance...
...physicians know little more about hay fever than Dr. Holmes did, their attitude is more optimistic. To them the disease which annually sets 6,000,000 U. S. victims gasping is a common form of allergy: a bodily sensitivity to certain foreign substances such as eggs, milk, wheat, horsehair, pollen grains, banana oil. Once these substances get into the bloodstream of sensitive people, there ensue such violent reactions as hives, vomiting, blinding headaches, and what Henry Ward Beecher lovingly called "irrepressible sternutation" (sneezing...
Naphthalene acetic acid and naphthalene acetamide are two of the "growth substances" or hormone-like chemicals, which growers now use to stimulate root-sprouting, accelerate pollen production, etc. etc. Dr. Frank Easter Gardner and his co-workers at the U. S. Bureau of Plant Industry station in Beltsville, Md. decided to try these two naphthalene compounds as a spray to keep ripening apples from dropping. They sprayed ten varieties of apple trees just before crop maturity, were signally successful in preventing premature falls. In Science last week they reported that in tests on one troublesome variety ("Williams Early Red") only...
