HOW ABOUT TOOTH BANKS?
Dental scientists are working on a new boon to mankindâ€”the transplantation of live teeth.
BY LESTER DAVID
SQUINT for a moment into the crystal ball labeled “Dental Science’s Coming Attractions.” Here’s the image: Sorrowful-looking gent shuffles into dentist’s office, points miserably to aching molar, sits down and opens wiâ€”ide.
Dentist gives him the needle, inserts forceps, yanks mightily. He throws away old tooth and goes to cabinet for new one. He selects nice, shiny molar from collection, plants it in patient’s mouth and sends him on his way.
About a month or so later, new tooth has established nerve, bone and blood vessel connections with jaw and happy patient has a live, serviceable chomper in his head to replace the one extracted.
Pressure Sack Saves Divers’ Lives
WHEN deep sea divers must be pulled up rapidly, without time to accustom themselves to the change in pressure, they become very sick. A German inventor has devised a pressure sack for this emergency. Divers are placed inside it as soon as they are pulled up, and kept under a gradually diminishing pressure for several hours. Iron chains surround the sack.
When there is not sufficient time to get a diver into the pressure sack, compressed air can be forced into his suit. Ropes are used to prevent suit from bursting.
Too Much Nudism Is the Bunk
ARGUMENTS for last summer’s fad of nudism based on the theory that the absence of clothes is good for health, are exploded editorially in the New York City medical periodical, American Medicine. Reasonable exposure of the skin to air, sunlight and the water of rivers or the sea has full medical support. Old-fashioned heavy and impervious clothing was condemned long before modern ideas of nudism were thought of. The point made by the medical editors is merely that it is not necessary to expose all of the body to air or sunlight or to expose it all of the time. The authorities are skeptical also of the moral and mental benefits claimed for nudism.
FIRST PICTURES OF PASTEUR INSTITUTE
Each day 8,000 tubes of vaccine and 12,000 tubes of serum leave one of the greatest centers of preventive medicine in the worldâ€”the Pasteur Institute, in Paris. It was founded by national subscription nearly fifty years ago as a laboratory for the great French chemist, Louis Pasteur, father of bacteriology. Now it is carrying on the work of this pioneer in preventive inoculation against disease, who died in 1895. The striking photographs of its activities which Popular Science Monthly presents here are the first ever permitted for publication.
While internationally famous doctors seek new cures for diseases in its research laboratories, an up-to-date factory makes tried and proved serums and vaccines.
Hospital Constructs Hibernation Room for Frozen-Sleep Care
TO CHECK the value of the new frozen-sleep method of treating cancer (P.S.M., Sept. ’39, p. 43), a refrigerated hibernation room has been set up at the Lenox Hill Hospital in New York City. Mechanical refrigeration equipment maintains the treatment room at a temperature of about sixty-five degrees F., so that the body temperature of the patient may be kept between eighty-eight and ninety degrees
Scientist Invents Nickel-in-Slot Blood Pressure Machine
EVERYONE has put a nickel in the slot to make a telephone call, to buy candy, gum, horoscopes, and various gewgaws and “prize” packages; but soon, according to Dr. George A. Snyder of Hollywood, Calif., it will be possible to get a blood pressure reading for the same price.
Since the public became aware of the fact that excessive blood pressure accounts for twenty per cent of all deaths of persons past 50 years of age, Dr. Snyder has kept pace with this growing interest by inventing a machine which will make it possible for individuals to keep a check on this condition with a minimum of cost and inconvenience. Any adult can operate the device.
DOCTOR DISPUTES LINK BETWEEN SMOKING, CANCER
The case against tobacco is derived mostly from statistical associations and some experimental work with animals, says Dr. Harry S. N. Greene, chairman of the department of pathology, Yale University Medical School. There is yet no sound proof that cigarette smoking is a cause of human lung cancer.
In a book, Science Looks at Smoking, by Eric Northrup, published by Coward-McCann, Inc., New York, Dr. Greene says this about his own smoking pleasures:
This is GENIUS. I’m going to buy an old Gravitron and charge an arm and a leg for centrifugalization treatment.
Old Age Rejuvenator Centrifuge
PERHAPS Ponce de Leon kept too far south in his search for the Fountain of Youth. He might have headed to Coney Island and there made himself young riding on a carousel, or a roller coaster, if a medical theory recently advanced is trueâ€”that, since old age is our final yielding to the inevitable, resistless pull of gravity, it is necessary only to overcome gravity and you overcome all that brings you down to earth. In describing trips to other planets, writers of science fiction have pictured the space travelers first crushed under intolerable weight during a few moments of ascent from the earth; then overwhelmed by a feeling of lightness, when all weight disappears. Indeed, there has been fear that too little gravity might have injurious effects on our bodies, unaccustomed to such a weightless condition; and that it would be as necessary to supply artificial gravity in a space ship as it would be to supply artificial air. However, no one seems to doubt that on the moon, or on Mars, freedom from the weariness of earthly weight would be pleasant.
MOUSE MILK $10,000 a quart
BY LESTER DAVID
THE Columbia University medical school has given M. D. degrees to 3,000 assorted black and white mice. The M. D. stands for Mouse Dairy.
Elsie the Borden cow would probably look down the side of her dainty nose at Juniper the Columbia Mouse because of the latter’s scanty milk output. Juniper yields a mere cubic centimeter every few months and the entire kit and kaboodle of 3,000 is good for only two quarts a year. Elsie can sniff but Juniper, in her academic robe and rakish mortarboard, can snub right back because Elsie just isn’t in her social class.
Scientific PEEP SHOW TELLS HOW OUR BODIES WORK
ILLUSTRATING with working models the many operations of the human body, a novel exhibition recently opened at the New York Museum of Science and Industry resembles the side show of a modern amusement park. By pressing buttons, turning cranks, and pulling levers, visitors can test their strength, their lungs, and their voices and see for themselves how blood circulates, how their muscles work, and a host of other interesting details. Controlled by a maze of motors, the exhibits provide a fascinating introduction to the mysteries of human anatomy and physiology.
