...Essential for the prevention of rickets in children, Vitamin D regulates the amount of calcium and phosphorus which the body uses for building bones and teeth. Only vitamin which does not originate in plant tissue, vitamin D occurs most abundantly in oily fish livers, is generated in the body by ultraviolet rays of the sun. Normal U. S. adults get all the vitamin D they need when they bask on beaches, and, if they drink plenty of milk, need not worry about calcium regulation. But to make best use of the calcium in their diet, pregnant women and children need...
...plan of attack which was moderately successful. We would row out into the ocean about 300 yards, then bore a hole six inches in diameter in the bottom of the boat, preferably near the bow. We would then rub around the edge of the hole a mixture of phosphorus and cheese (any sharp cheese would suffice). The light from the phosphorus and the tantalizing odor accompanying it would invariably attract any whifflepoofs lingering beneath us. We hovered over the hole, with rubber bands stretched out in our fingers. As soon as a whifflepoof would thrust his inquiring snout through...
...grant had been made to study the bacillus under the new world's biggest "cyclotron" or atom-smashing machine at the University of California, which weighs 225 tons and has just produced a record-breaking beam of 19,000,000-volt particles. By stuffing the bacillus with radioactive phosphorus produced in cyclotron bombardments, the California researchers will ry to make it give off a continuing stream of telltale emanations. Then, after injection into laboratory animals, the emanating germ's first furtive fortnight may be observed...
...mice. A regular program of medical cyclotron work was set afoot, in charge of the inventor's brother, Dr. John Hundale Lawrence, who has a medical degree from Harvard. One of his latest discoveries, announced last week, is that different types of cancer cells assimilate the element phosphorus at different rates. This was learned by attaching radioactive tags to phosphorus atoms and shooting them into cancerous mice. It may eventually yield valuable clues for cancer treatment...
Said Dr. Martin, warming to his subject, a mother's emotions have great influence upon her child's teeth, even before the baby is born. A woman who is anxious, apprehensive or resentful during pregnancy may not bother to eat tooth-forming foods (calcium, phosphorus and vitamins). After the child is born, she must be the thermostat to the "emotional climate of the home." A mother who pampers her child never lets him get his teeth into anything. Consider the Eskimos, said Dr. Martin. They "use their teeth for everything, including softening frozen leather," and Eskimos rarely suffer...
