.... reported negative side-effects. Various studies have claimed that cannabis destroys brain cells. However, several other studies found no structural or neurochemical atrophy in the brain at all. Furthermore, it should be noted that Heath's work was sharply criticized for avoiding safeguards of bias and reporting "changes" that occur normally in the mammalian brain. Wu et al. found a correlation between cannabis use and low sperm counts in human males. This is misleading because a decrease in sperm count has not been shown to have a negative effect on fertility and .....

.... that emerged led directly into the natural world- the shapes of clouds, the paths of lightning, the microscopic intertwining of blood vessels, the galactic clustering of stars." (Gleick, 1987) The man most responsible for coming up with the Chaos Theory was Mitchell Feigenbaum, who was one of a handful of scientists at Los Alamos, New Mexico when he first started thinking about Chaos. Feigenbaum was a little known scientist from New York, with only one published work to his name. He was working on nothing very important, like quasi periodicity, in .....

.... more correctly defines the clinical pathologic disease caused by an immune-mediated sensitivity to gluten, a protein found in many cereal grains, principally wheat, barley, rye, and to a lesser degree oats. Most nutritionists agree that gluten is not present in rice, white or sweet potatoes, and corn. Over 100 years ago a British physician named Samuel Gee described the "coeliac affection." Dr. Gee observed the syndrome in people of all ages, but especially in children who had chronic diarrhea, weight loss, edema, and a distended abdomen. The led to deat .....

.... increase for some kinds of cancer. Doctors at UT Southwestern Medical Center at Dallas say before you start drinking for your health, talk to your doctor. For some people, the risks of alcohol outweigh the benefits. And remember that while one drink a day can be helpful, more can be harmful. Could a drink a day keep the doctor away? One study says alcohol can have beneficial effects. Doctors recently determined that people who drank moderately, about one or two drinks per day, had a lower chance of developing blocked arteries in their legs. This condition result .....

.... French explorers knew of sources of native copper in the region of Lake Superior and the area natives had copper jewelry and ornamentation. Earnest copper mining began in Simsbury, Connecticut about 1709 and copper was actually exported to England after a source was discovered in New Jersey around 1719. In later times domestic copper resources did not satisfy national needs until the discovery of gold in California shifted the focus of mineral exploration westward and strikes of rich copper ores occurred in Tennessee and the Cordilleran base regions. The C .....

.... them, then the muscles heal quicker adding more fiber increasing their bulk. Many athletes turn to steroids more often because they're cheaper then marijuana or cocaine. A ten week cycle of testosterone cypinate and methandrostone costs only about one hundred dollars. Steroids are also very hard to trace because of their water base composition. They can pass through the body within two days. All these benefits of steroids help an athletes become more competitive and increase their chance of being a winner. Of course everybody wants better biceps a .....

.... of air and ozone makes up only 3 x 10-5 percent of air. Furthermore, this minuscule amount of ozone is enough to protect the earth from most ultraviolet light. Ozone prevents most UV-B radiation from reaching the surface of the earth (Environment Canada, 1996). Ozone is very important to life on earth because the harmfulness of high-energy UV-B radiation stems from the high energy of these light rays, enabling them to penetrate deeply into water, plant tissue and epidermal tissue of animals. Increased UV-B radiation results in harming the metaboli .....

.... and these are increasing in size annually. Paradoxically, ozone is toxic! Undiluted ozone is bluish in colour. Liquid ozone is bluish-black, and solid ozone is violet-black. Oxygen is very reactive and capable of combining with most elements. It is essential for respiration of all plants and animals and for practically all combustion. history of oxygen Leonardo da Vinci suggested that air consists of at least two different gases. Before then, air was felt to be an element in its own right. He was also aware that one of these gases supported .....
