A Valuable Discovery The laser is a marvelous device that sends out a slender, concentrated beam of light, a light that surpasses the light at the sun's surface. So vast is the laser beam's power that it has without a doubt the capacity to vaporize* any substance located anywhere on earth. The laser can penetrate steel, pierce a diamond, or make an accurate die for wire so thin that it can be seen only with a microscope.Grateful eye surgeons report that they have used laser beams to repair the retinas in some fortunate* patients by creating tiny scars that joined the retina to the eyeball. Pioneering* medical men are making cautious exploration* into cancer cures with the laser, confident that they will alter* the course of this brutal* disease.
Bible Zoo One of the most popular tales of the Bible depicts the great flood that destroyed every mortal except Noah and his family and the animals on his ark. Should there be a repetition of that disaster, there is one place where all the biblical animals are already gathered. The man to be commended for this novel collection is Professor Aharon Shulov, a zoologist at Hebrew University in Jerusalem, Israel. Professor Shulov appointed himself a committee of one to search out the 130 creatures mentioned in the Old Testament. Among the occupants of this zoo are crocodiles, camels, apes, peacocks, deer, foxes, and sheep, some of whom had to be imported from other lands. They are settled in suitable quarters on a twenty-five acre site in Jerusalem. Visitors to the zoo not only get to view and feed the animals, but they are also treated to quotes from Bible verses that encourage the study of the Good Book and teach morality amidst the waddling of the ducks and the wailing of the wolves. Not surprisingly, the children have the final word at a special corner of the zoo, called the Garden of Eden, where animal cubs roam freely, attracting the attention of hundreds of youngsters who visit daily.
Protecting Our Health Pick an apple, a tomato, a peach-no worms in the harvest. We are familiar with the abundant use of pesticides by farmers, but today's chemists are becoming uneasy. They calculate that there are 45,000 different pesticides, and all of them can be absorbed by the fruit on which they are sprayed. The chemists estimate that every morsel we eat in the future may contain a deadly quota of pesticide. The tragedy* will come slowly but the threat is real. These government chemists do not suggest that we ban pesticides. They are cautious* and do not easily panic. What is needed, they say, are appropriate, budgeted* doses that will not pollute* our food.
A Course for Parents A course entitled "The Responsibilities of Parenthood" sounds as if it should be offered to students who are immediate candidates for parenthood. Not according to Dr. Lee Salk, who feels that teaching children about parenthood should precede the adolescent years. Dr. Salk, of the New York Hospital, teaches a volunteer coeducational class of junior high school youngsters what it means to be a parent. He does not lecture or present radical views. Rather, he conducts spontaneous discussions by encouraging students to imagine that they are parents and asking them such questions as "What would you do if you found your child smoking?" or "How would you prepare your child for the first day of school?" The lessons skim over such topics as the need to vaccinate children against diseases or to teach them not to be untidy or to use utensils properly. The class is more concerned with preparing students emotionally to become better parents some day and with making children sensitive to the responsibilities of parenthood. The class members often express temperate and mature views. One girl said she would not approve of having a nurse bring up her child. Another felt that money earned through baby-sitting or other jobs should be shared with parents. When asked how his students rate, Dr. Salk retained a hopeful outlook. "They are ready for this information," he declared. "I think they'll be honest parents."
