...perfect pearl, formed not in an oyster but in a coconut, was exhibited last week in Florida by Botanist David Fairchild. One of a dozen found in 9,000,000 East Indian coconuts, the pearl began (scientists believe) when a sprout was unable to force its way through one of the three pores in a germinating nut. Like a sand grain in an oyster, the sprout was then encrusted with layers of calcium carbonate-even though chemists have never found this compound in either the nut's milk or kernel...

...Frederick W. Malley of Texas discovered that this wasp, a U.S. native, was a weevil parasite. In 1938, the Clayton Foundation, founded by famed Cotton-man Benjamin Clayton, put scientists to work on the wasps' use. Directed by Botanist Glenn W. Goldsmith, young Entomologist John M. Carpenter studied the insect, announced last week that it can be propagated in honey-smeared cages, released in fields to work as effectively as the unpampered outdoor variety. He is now devising equipment for mass production of the billions of wasps which cotton growers need...

...plants to manufacture food out of carbon dioxide and water in the presence of light. Selective breeding, long practised to increase the yield of plants, may eventually be looked back on as little better than superficial when compared with a new method described last week by Cornell's Botanist Lewis Knudson. Using X-rays, Knudson has permanently increased the size of plants' cnloroplasts-the cell's tiny granular bodies where chlorophyll makes sugar and starch out of inorganic matter by the process of photosynthesis-most important chemical reaction in the world...

...Botanist Knudson suspects that the bigger its chloroplasts, the bigger is a plant's power to synthesize food for its own growth-and for the nourishment of man and beast. So Knudson's colleagues are eagerly planning to adapt his method to develop more productive strains of corn, wheat, clover, other crops...
