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.
My brother, the Gentleman The story of Sir Walter Raleigh who spread his cloak on the ground to keep Queen Elizabeth from the hardship of crossing a muddy puddle can qualify that nobleman for an award as a man of tact and good breeding. My brother Kenny, a bachelor with a keen interest in history, was impressed by that anecdote and thought he might demonstrate his excellent upbringing in a parallel situation.
lnhe Frozen Future Doctors are always devising* new cures for diseases that kill people. But suppose you are dying from an incurable illness now. If only you could postpone death until a cure was found! Now some people are trying to do just that. One young man consented to having his body frozen and placed in a massive capsule in order to preserve it until doctors find a cure for his disease. Some peopie have denounced this unique experiment with a torrent of angry words. They resent human attempts to molest the natural order of life and death. There is also a gloomy fear that the world is already overcrowded and that people have to die to make room for those who are about to be born. If the experiment works, unforeseen problems undoubtedly* will arise.
