Copies of a British scientific magazine which arrived in the U.S. last week contained a report by famed British biologist J. B. S. Haldane of his experiments in the physiology of submarine crews. One of his 20 human guinea pigs was Dr. Juan Negrin, Premier of Spain during the last days of the Civil War. Under terrific air pressure, 53-year-old Dr. Negrin and the other subjects (mostly exiles) writhed with the bends, screwed up their faces with the pain of hammering headaches, as Professor Haldane tested the bodily effects of gases at various pressures...
Novelist John Steinbeck and his biologist friend. Director Edward F. Ricketts of the Pacific Biological Laboratories, decided to make an expedition to the Gulf of California, Mexico's long Pacific arm which used to be called the Sea of Cortez. They wanted to find out all they could about the sea creatures, especially the teeming invertebrates along the shores-how they changed in numbers, size, form from place to place, how they lived, loved, ate, fought, fled, hid, died...
This ingenious research trick was announced last week by Biologist J. O. Ely of Philadelphia's Franklin Institute. The old way of finding out where the bacteria went was either by 1) microscopic postmortem examination of tissues or 2) test-tube culture of tissue samples until bacteria appeared in obvious numbers. But hereafter scientists need only feed the bacteria on elements made mildly radioactive in a cyclotron (TIME, June 23), then can trace them through the animal body by the particles of subatomic radiation which they give...
...Biologist Ely nurtured a colony of mixed (Escherichia coli and Staphylococcus aureus) bacteria on sodium phosphate whose phosphorus was radioactive. Next he injected them into the tail veins of rats. Few hours later he analyzed the rats' organs for radioactivity, found it greatest in the liver and the lungs, weakest in the brain. Concluded Ely: "The brain, apparently, has an effective means of preventing bacteria from entering it in large numbers." Further significant conclusions will probably appear as work progresses with this new technique...
Salesman. In Philadelphia, the Better Business Bureau hunted an elusive peddler who sold tired lawnmower-pushers seed for strictly "two-inch grass." Research. At Troy, N.Y., an experimenting biologist proved to his own satisfaction that the larger a goldfish's eyes, the less it sees...
