That diabetes, heretofore considered a disease of disarranged metabolism, is caused by an ultramicroscopic germ or filterable virus is suggested by experiments on rabbits by Dr. D.H. Bergey, professor of hygiene and bacteriology of the University of Pennsylvania.
By infecting rabbits with carefully filtered secretions from diabetic patients, Dr. Bergey was able to produce the first stages of diabetes in the animals. He also found that the infective agent increases in strength when it is cultured in broth, just as well-known visible germ do.
The ancient fossil bone found in Java this summer and reported as a companion of Pithecanthropus, the oldest man-like creature known to science, is proved to be a most unusual freak of nature. This conclusion was announced by Dr. Ales Hrdlicka, noted anthropologist of the U.S. National Museum, following careful study of a photograph just received from Dr. C.E.J. Heberlein, discoverer of the "skull."
Dr. Hrdlicka and Dr. Gerrit Miller, zoologist of the museum pronounce the Javanese fossil, which has attracted so much attention, to be the leg bone of an ancient elephant, preserved by some remarkable chance, so that it happens to resemble closely the form and size of a prehistoric human skull.
A method of cutting off three-inch pieces from a beam of light, like a meat cutter slicing a bologna sausage, though the light moves at 186,000 miles a second, is described by Dr. Ernest O. Lawrence and Dr. J.W. Beams of Yale University.
Though light travels so fast that it can encircle the earth seven times in a second, the two physicists made use of a shutter that turned the light on and off with such rapidity that each "piece" of light was along about three inches in length. Each flash lasted a hundred billionth of a second.
