For the last few decades, cloning was a fictitious idea that lay deep within the pages of some sci-fi novels. The very idea that cloning could one day become reality was thought to be a scientific impossibility by many experts but on one exhilarating day, what was thought to be "purely fiction" became reality. That fine day was February 22, 1997. A team from the Roslin Institute which was lead by Dr. Ian Wilmut changed the face of history forever by revealing what looked like an average shee

In the world's oceans, the surface currents move the oceans' surface water. This occurs in the Atlantic, Pacific and Indian Oceans. From a diagram of these surface currents, a number of conclusions can be made about the general patterns of the surface currents. One of these conclusions includes that they go clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere. The Northern Pacific circulation goes around in a clockwise rotation. The same thing happens in the Nort

Down Syndrome Down Syndrome is caused by a trisomy of the 21st chromosome, which means that there are three of chromosome 21 instead of 2. Symptoms of the disorder include: mental retardation, abnormal creases in the palm, a flat face, sparse and strait hair and short stature. People with Down syndrome are also at a high risk for cardiac anomalies, leukemia, cataracts and digestive blockage. Fifty percent of babies with the syndrome die before age one. Down syndrome can be detected by

Could an exploding star have been responsible for the death of the dinosaurs? This idea has become popular again as an explanation for the disappearance of the dinosaurs. An exploding star can blast material enormous distances into space. If this material reached Earth's atmosphere, changes may have occurred that were harmful to life. We call an exploding star a supernova. Nova is the Latin word for new, and in ancient times, when an exploding star was observed, people often thought a ne
