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...

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.

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.

If there is no one, all of you have to submit to my rule and be my...

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.

House Husbands' Heart Risk

Most people assume that life in the rat race is bad for your health. But reversing the traditional gender roles, being a house husband is a stressful business, according to the latest research by American scientists.

The water used for irrigation is taken lakes, rivers, streams, and wells. In the mid - 1980’s, about 220 million hectares of land were under irrigation through out the world’s driest continent.  The amount of water needed for farming varies with the type of crop and the climate. For example, rice requires more water than cotton. Wheat grows in a warm climate needs more water than wheat that grows in cool climate. Any form land must receive enough water to allow both for plants growth and for the...

Alternative medicine

         Alternative medicine is, by definition, an alternative to something else: modern, Western medicine. But the term ‘alternative’ can be misleading, even off-putting for some people. Few practitioners of homeopathy, acupuncture, herbalism and the like regard their therapies as complete substitutes for modern medicine. Rather, they consider their disciplines as supplementary to orthodox medicine. The problem is that many doctors refuse even to recognize ‘natural’ or alternative medicine, to do so calls for a radically different view of health, illness and cure. But whatever doctors may think, the demand for...

How a Volcano Really Works

     As it rises, the pressure of the rock around and above it becomes less and less. At a certain point, that pressure drops so low that it cannot keep the rock balloon solid any more. The balloon melts. It becomes an underground liquid that we call magma - a liquid imprisoned in an underground chamber of the solid rock around it.        Ordinary steam, heated to only 212° f  (100 °C), can drive a locomotive. Now try to imagine the power of super-steam, heated to 3000°F (nearly 2000 °C).        Early explanations for the awesome power of volcanoes involved...
