Scientists made a great breakthrough this year in England when the first "testtube" baby was born. The birth was the result of many years of research by doctors. The doctors did the research insgroupsto help the women who cannot conceive a baby in the normal way.
What happened when the baby was born "from a test tube"? Well, the baby did not literally grow in a test tube. The first stage of the process was that the egg from the woman and the sperm from the man were put together in the test tube. After all, the embryo was put into the womb of a woman. This process was difficult. But it was successful, so the baby was eventually born, like any other, from a woman, only the woman wasn't the baby's real mother, but a sort of "carrier" of a baby produced by another couple.
Obviously, this method is help to couples who can't have children because of physical problems in the woman. But very difficult moral problems arise in the kind of situation. Take, for instance, a case that happened this year. A couple who wanted a baby advertised for a woman to have a child by the father of the couple. They offered the woman a lot of money. The woman was made pregnant by artificial insemination; in this case, the woman "employed" to bear the child was its real mother. When the baby was born, the woman refused to give it back to the couple. But, in the eyes of the law, the woman had a right to keep the children because she was its biological mother.
You could argue that we should change the law to deal with this kind of situation. In earlier times, there were always healthy babies needing adoption, because family planning methods were not so effective as they are now. These days, however, most of the children who can be adopted are over six years old, often handicapped in some way. So a couple who want a young healthy baby cannot always adopt one, this is why the "testtube" baby is in demand. But is it normally right to use this method? Should we temper with nature in this way? Even if we change the law, would this be the right step to take?

Can you imagine travelling to work in a oneman submarine? Some scientists believe that some day oneman submarines will be as many as automobiles are today. A famous French driver says,"One day soon, men will walk on the ocean floor as they do on the street!"Perhaps during your lifetime people will travel, work, and live in the sea.
If human beings want to live in the ocean, many human problems will need to be studied first.
Some of these problems, similar to those of living in outer space, are pressure, lack of oxygen and weightlessness. Many questions are still unanswered. For example, can our blood make itself fit for underwater surroundings? What will happen to our muscle if we live in the water very long? Scientists are looking for answers.
Perhaps in the future man will live in the sea, away from the crowded and noisy cities on land. Then sea has plenty of space, not only for floating living buildings and parks, but also for storing supplies and for underwater travel.
Some scientists believe that ocean living will benefit man in more than physical ways. In the freedom and beauty of the deep sea, man may find new sources of joy.

If you know anything about violin music, you have perhaps heard the word "Stradivarius". Stradivarius is the name for the worlds most wonderful violins. They are named after their creator, Antonio Stradivari.
Stradivari was born in northen Italy and lived from 1644 to 1737. Cremona, the town he lived in, was a placeswheresviolins were produced. Stradivari was very young when he learned to play the violin. He grew to love the instrument so much that he began to make them himself.
Violins were new instruments during Stradivaris time. People made them in different sizes and shapes and of different types of wood. Stradivari is said to have been very particular about the wood he selected for his violins. He took long walks alone in the forest to find just the right tree. He is also said to have used a secret and special type of varnish to put on the wood. Whatever the reasons are, his violins are the best in the world.
Stradivari put such care and love into his violins that they are still used today. Many, of course, are in museums. But some rich musicians, who can afford the thousands and thousands of dollars they cost, own Stradivarlus vilolins.
Stradivari passed his methods on to his sons. But the secrets of making Stradvarius violins seem to have died out with the family. Their rarity, as well as their mellow sound, made Stradivarius violins among the most prized instruments in the world.
