NO WIRES ON RADIO KNIFE
Surgeons hail a new radio knife, devoid of wires, as an outstanding advance. Previous types have long employed high-frequency currents like those of radio, led through a dangling cord, to make clean, bloodless cuts in tissue. The latest apparatus dispenses with any electric connection and leaves the surgeon’s hands unencumbered in a delicate operation. An insulated electrode behind the patient’s back charges his skin, and the surgeon’s scalpel absorbs enough energy at the
point of contact to divide the tissues cleanly.
DISPUTED PATERNITY CASES
by H. W. Secor
Among the most difficult types of disputes handled by courts of law are those seeking to determine the real father of a child.
IN 1945, a California jury decided that Charles Chaplin was the father of Carol Ann, daughter of Joan Barry. The jury’s decision cost the famous comedian over $100,000 for attorney’s fees and a sizable sum each month for the support of the girl until she reached the age of 21.
“The irony of it all,” says genetics counselor Sheldon C. Reed, “is that Chaplin is not her father. … By the laws of heredity he is excluded as a possible father.”
This trial was one of the most famous of the cases known as “disputed paternity cases.” They are among the most difficult types of disputes which are handled by our courts of law.
Bed Rolls Over
A “sandwich” bed for severe fracture cases, who have to be turned over several times a day, has simplified what used to be a difficult and painful process. The bed has a mattress that rotates within a metal frame. When a patient lying on his back needs to be turned over, a second mattress is placed on top of him and fastened by wing nuts at the ends of the frame. Then the bed is turned over and the uppermost mattress is removed, leaving the patient lying on his stomach.
THE CURE FOR STAMMERING
WITH phonograph recordings, a new kind of lip training, and delicate electric brain-wave detectors, scientists are waging a winning war on stammering. Their researches mean new hope for the 1,000,000 or more Americans who suffer from the ailment. Do you stammer? Whether you do or not, you can join the nation-wide fight to end the personal suffering and the $1,000,000,000-a-year economic loss caused by disordered speech. Experts have now discovered such simple methods of treatment that nearly anyone can cure himself, or show a friend how to do it.
These findings spring from the latest work in speech-correction clinics throughout the country, where every modern scientific weapon helps treat even the most refractory cases of stammering. Enter one of the most advanced of these institutions, headed by Dr. Lee Edward Travis at the University of Southern California, and you will see how research and actual treatment go hand in hand.
Secrets of Cures by Ancient Medicine Men
by EARLE R. BUELL
Cheer up, have faithâ€”it’s good for your health. That’s the verdict of scientists who have been experimenting to determine effectiveness of remedies employed by ancient medicine men, astrologers, and modern faith healers. This article explains why some people actually do get well when they have a strong belief they are going to get well.
OPTIMISM is better than apples for keeping the doctor away. There is a scientific basis for faith healing.
Even some ancient superstitions had healing power and the hocus-pocus of the tribal medicine man may have saved many lives.
These are some of the conclusions arrived at by a group of experimenters who have been endeavoring to test out the effect of states of mind upon the general health.
This was written by Francis Crick, co-discoverer of DNA, about a year after they figured out it was a double-helix. In fact, in the article it’s still a bit of a hypothesis that DNA is a double-helix, they haven’t proved it yet.
The Structure of the Hereditary Material
An account of the investigations which have Led to the formulation of an understandable structure for DNA. The chemical reactions of this material within the nucleus govern the process of reproduction
by F. H. C. Crick
Viewed under a microscope, the process of mitosis, by which one cell divides and becomes two, is one of the most fascinating spectacles in the whole of biology. No one who watches the event unfold in speeded-up motion pictures can fail to be excited and awed. As a demonstration of the powers of dynamic organization possessed by living matter, the act of division is impressive enough, but even more stirring is the appearance of two identical sets of chromosomes where only one existed before. Here lies biology’s greatest challenge: How are these fundamental bodies duplicated? Unhappily the copying process is beyond the resolving power of microscopes, but much is being learned about it in other ways.
One approach is the study of the nature and behavior of whole living cells; another is the investigation of substances extracted from them. This article will discuss only the second approach, but both are indispensable if we are ever to solve the problem; indeed some of the most exciting results are being obtained by what might loosely be described as a combination of the two methods.
Unique Bed Loom Gives Invalids Fun and Exercise
Keeping young patients entertained while exercising their muscles at the same time is the purpose of the invalid’s weaving loom pictured at the left. The invention of Margaret Gleave, a nurse at the James Whitcomb Riley Hospital for Children, in Indianapolis, Ind., the loom is operated by youngsters suffering from leg and hip diseases to help them exercise their afflicted limbs. The invention won a fifty-dollar prize for the nurse.
800-lb. Magnet Treats Eye Injury
AN EYE magnet so powerful that it will pull a flatiron across a room has recently been installed in a Minneapolis, Minn., hospital to remove steel cinders from patients’ eyes. It is the largest eye magnet in the world and weighs over 800 pounds. One and one-half miles of copper wire are wound in the apparatus, which uses a 220-volt current.
USE SEESAW TO START STOPPED HEART
A life-saving seesaw has been invented by a University of California scientist to revive those whose hearts have stopped, as the result of certain kinds of accidents. While oxygen is forced into the lungs and heat is applied to the body, the patient will be rocked steadily up and down on the pivoted plank, to which he will be strapped lying on his back. The theory is that the steady change in position will cause gravity to send the blood coursing through the veins and will start the heart beating. The apparatus, the inventor points out, is for use only in certain cases where the patient has met with an unusual accident.
How Music Heals the Sick
PHYSICIANS, SURGEONS, AND MENTAL SPECIALISTS FIND THAT MELODY HAS WEIRD EFFECTS ON PHYSICAL HEALTH
By E. W. Murtfeldt
BEETHOVEN’S Moonlight Sonataâ€”three times a day. That is how doctors’ prescriptions may read in the near future, according to reports from the world’s leading medical centers. For in laboratories, hospitals, prisons, and mental clinics, research experts are uncovering strange facts that throw new light on the weird effects of music on our physical and mental health.
Just recently, for instance, Prof. S. V.Kravkov, a Russian scientist, discovered that music and similar sounds can even improve a listener’s eyesight as much as twenty-five percent. As little as the rhythmic ticking of a clock, experiments showed, served to stimulate the vision. A practical application of the discovery, the Soviet professor points out, is expected to serve as an aid to astronomers, microscopists, engravers, and others whose work depends on the strength and accuracy of the eyes. Even more astonishing, however, are tests being carried on in this country. Not long ago, Moissaye Boguslawski, famous pianist, conducted a series of novel experiments in a Chicago hospital for the insane. Seated before an Italian mother so mentally deranged that she refused to look at her young baby and demanded that she be treated like an animal, Boguslawski played a group of Italian melodies ranging from nursery tunes to folk songs. The woman showed no reaction until he began an aria from the opera “II Trovatore.” Before he had finished, the patient began to weep and begged attendants to bring her baby to her.
