The Scientist Help Sheep Dies

Keith Campbell, a prominent biologist who worked on cloning Dolly the sheep, died at 58, the University of Nottingham said Thursday. Campbell, who had worked on animal improvement and cloning since 1999, died October 5, 2012, University spokesman Tim Utton said. He did not specify the cause, only saying that Campbell had worked at the university until his death.

He began researching animal cloning at the Roslin Institute near Edinburgh in 1991. In 1996 the experiments led to the birth of Dolly the sheep, the first mammal to be cloned from an adult cell.

The sheep was named after the voluptuous singer Dolly Parton. Researchers at the time said that the sheep was created from a mammary gland cell, and that Parton offered an excellent example.

The creation of the sheep captured the public imagination and instantly became a scientific sensation. The experiments drew not only admiration but also anger from some who raised questions about the ethics of cloning. Animal rights activists were outraged, while the church of England expressed reservations. Dolly was put down in 2003 after she developed a lung disease. Campbell's interest in cellular growth dated back to his college days studying microbiology in London.

Higher Education for Women

In this modern era, there are still some parents who are reluctant about sending their daughters to college. The narrow attitude shown to women's education is largely due to the traditional role of women in society. A woman is expected to be a wife and a mother. Most parents believe that if their daughter gets married and chooses to be a housewife, then the higher education will be a waste. However, an educated woman is not only a better wife but also contributes something to the society.

Nowadays, more and more women are successfully combining their career and marriage. Educated women are richer both emotionally and financially. They are able to find an outlet for their monotonous drudgery of their housekeeping. They bring more satisfaction and contentment to their lives.

Depriving girls of higher education is crass discrimination. Times have changed; modern society needs the talents of its people regardless of gender. Today, women work alongside men. In fact, in the last few decades, women have made outstanding contributions to society.
Women should be given the freedom to be educated whether or not they get married or go to work after finishing their education, because it is only through education that a woman will find herself useful and discover what she wants in life. A woman who works is not an insult to her husband. Conversely, her husband should feel proud of her achievements since marriage is actually an equal partnership.
Therefore, parents should not think that girls should receive less education just because they will get married one day.

Adoption

Adoption is the process by which people take a child who was not born to them and raise him or her as a member of their family. By law, adopted children differ from foster children. An adopted child has all the legal rights of a member of the family that raises him or her. A foster child does not.

Parents place their children up for adoptions for many reasons. Some parents feel they cannot adequately care for their off springs because of health or economic conditions. Some others, especially unwed parent, may not want to raise a child.

But there are couples who cannot have children of their own. Adoption gives them opportunity to raise a family. They can get one from an adoption agency if they have all the requirements asked.

State laws prohibit adoption agencies from revealing the identity of the natural parents to the adoptive parents. These laws also forbid agencies from disclosing the identity of the adoptive parents to the natural parents. In some states, the law permits adopted persons who are at least 18 years old to see their birth certificates including the natural parents' names.

On the contrary, many adopted people worked to change the laws. They argue that people have a right to know their identity. They said that keeping secret their adoptions records violate their right.

On the other hand, many people feel adoption records should be kept secret. If not, natural parents might change their minds years later and take the child away from the parents who raised him or her.

Some experts advise that a child should know of the adoptions by the age of 6 or 7. Surveys have shown that most adopted children develop normally.

Let's Make the City Clean and Fresh

A clean and fresh city will surely make the inhabitants healthy. Every morning especially in dry season, all roads must be watered with clean water and swept by the workers of regional government under the mayor's instruction.

To protect people from heavy pollution caused by cars, trucks and motorcycles, enough trees must be planted along the roads. Every building or house in the city must be surrounded by short and small trees which bear colorful flowers.

Bad and improper habits which cause disadvantages, such as smoking and throwing rubbish anywhere should be stopped at once.

The city mayor will have to think over the way to educate people, so they realize how important cleanliness and health are. More public lavatories are badly needed.

It will be wise if the city mayor decides a certain amount of fine to be paid by those who break the government regulation on cleanliness matter, For example, a man who urinates not at a lavatory, smokes not at a smoking room or throws rubbish at the roads should be fined. Besides dirtying the environment with cigarettes' butts, smoking will also cause pollution and bad lung diseases to other people.
So, bad habits and impolite attitude should be immediately stopped, otherwise the city will be dirty, unhealthy, badly polluted and will never attract foreign and domestic tourists as well.

The Rabbit's Revenge

Long, long ago a rabbit and a lion were neighbors. The lion was very proud, and was fond of boasting about his strength. And though they were such close neighbors, the lion looked down upon the rabbit, and used to bully and frighten her. Finally, the rabbit could stand it no longer and wanted to get her own back.

One day she went to the lion and said, "Good day, respected elder brother. Imagine it, I met an animal over there who looked exactly like you, and he said to me, Is there anyone in the world who dares stand up to me? If there is, let him come and have a duel with me. If there is no one, all of you have to submit to my rule and be my servants!". "Oh, he was an intolerable braggart! He is so puffed up with pride that his eyes can't even light on anyone!", added the rabbit.

"Oho," the lion said. "Didn't you mention me to him?"
"Yes, indeed," the rabbit replied. "But it would have been better if I hadn't. When I described how strong you were, he just sneered and said dreadfully rude things: He even went so far as to say that he wouldn't take you for his attendant!"
The lion flew into a rage and roared, "Where is he? Where is he?"

So the rabbit took the lion behind a hill and, not going too near herself, pointed to a deep well from a distance, and said, "He is down there, in the well."

The lion hastened to the well and glared angrily into it. Yes, there was his rival who even glared back at him angrily. The lion roared, and his enemy roared back. The lion became so furious that his hair stood on end. So did his enemy's in the well. The lion showed his teeth and lashed out with his paws to' scare his rival. and his enemy in the well retaliated!

How Chocolate is made?

Have we wondered how we get chocolate from? Well this time we will enter the amazing world of chocolate so we can understand exactly how chocolate is made.

Chocolate is taken from a tree called cacao tree. This tree grows in equatorial regions, especially in places such as South America, Africa, and Indonesia. The cacao tree produces a fruit about the size of a small pine apple. Inside the fruits are the tree's seeds. They are also known as coco beans.

Next, the beans are fermented for about a week, dried in the sun. After that they are shipped to the chocolate maker. The chocolate makers work by roasting the beans to bring out the flavour. The beans from different places have different qualities and flavour. So they are often sorted and blended to produce a distinctive mix.

The next process is winnowing. The roasted beans are winnowed to remove the meat nib of cacao bean from its shell. Then the nibs are blended. The blended nibs are grinds to make liquid. The liquid is called chocolate liquor. It tastes bitter.

All seeds contain some amount of fat and cacao beans are not different. However, cacao beans are half fat. It is pure bitter chocolate.
