...originally was an aggregation of cold substances which gravitation pulled into a tight little planetary mass somewhere between 50 million and two billion years ago. Ever since, radioactive elements in Earth's material have been driving energy towards its centre until today the core of Earth is a hot fluid mass of iron, nickel, radium and other heavy elements 4,000 miles in diameter surrounded by a rocky shell 2,000 miles thick. As eons pass, "the persistent release of atomic forces continue, and will continue to supply heat and melt the surrounding shell with the result that Mother Earth...
...spirally coiled glass tube, resembling a hot water heater. The top opening of the Lindbergh tube was connected to the bottom opening by a straight glass tube, and the liquid sealed into the closed tubular circuit. By standing the coil on end and wobbling it, centrifugal force pushed the fluid up to the top of the spiral. There the fluid sloshed over into the straight down tube, and back into the bottom of the coil...
This was a germ-proof pump. By suitable ingress and outlet, Dr. Lindbergh was able to force oxygen or other gases into the continuously circulating fluid and draw it off again. Thus he had a mechanical duplicate of the lungs, heart and blood vessels. Nothing remained but to modify this apparatus so that Dr. Carrel could attach a heart, kidney or ovary...
...medicine, the staff of London's Middlesex Hospital last week was able to report perfection of a slow and safe method of transfusing blood. One of those helpful procedures is the preservation of human blood by the addition of substances to keep it in a clear, unclotted, fluid condition. Thus gallons of blood may be accumulated from donors, kept in a refrigerator until needed for a transfusion. The other helpful procedure is venoclysis, the slow drop-by-drop introduction into a vein, through a hollow needle, of a salt or a sugar solution, which a patient needs to support...
...anemia of the brain in some Colgate students, added the following to the A. M. A.'s explanation: "We still have to discover a definite scientific basis for the practice of sleeping head forward on trains. . . . Hemastatics may justify head forward position, since with the head forward the fluid inertia of the blood would cause it to accumulate in the splanchnic (abdominal) pool and thus render the brain relatively anemic. This would increase drowsiness and assist in going to sleep in the noisy and vibrating berth, but would not necessarily make the sleep one whit more refreshing, in fact...
