.... from the golden gods to the fair-skinned "burn 'n peelers", which results in a copious amount of lotions and creams being slathered on everyday. These lotions are, usually, sunscreens or sunblocks, meant to protect us from the blisters, the pain, and in general to keep our youthful glow lasting just a few years longer. A sunguard is a cream designed to protect one's skin from being sunburned. Our bodies are incrementally damaged by each new exposure to the sun, and this damage can later be seen in the form of wrinkles, blotchy skin and even skin cancer. Sunscreens have evolved a goodly amount over the years. Christopher Columbus noticed in 1492 that the nati .....

.... on this matter. Some people realize that problems exist, but most are cynical the process of fixing them. Rather than sharing constructive criticism about what should be done, they simply mock the existing methods. Some people think that by fixing one problem we are undoubtedly creating another one. One writer uses the analogy of a “mixing bowl” to describe the earth. This “mixing bowl” that is our earth is constantly being manipulated to create the perfectly balanced “mixture” (Huber). Since there will never be a perfect balance or “mixture”, what is the point of even trying? Maybe they are right in saying that we will never find the perfect mixture, bu .....

.... is viewed as being composed of three kinds of elementary objects: quarks, which make up neutrons and protons; leptons, which include electrons and some similar particles; and bosons, or vector mesons, which include the photons seen as light and which carry the electromagnetic force. Some scientists suggest that leptons and quarks may actually be the same object but in different states. Bosons, too, may be this same object but in still another state. The everyday world is made of molecules. Because molecules are so small, their existence was not easy to establish. Indirect evidence for molecules was strong during the second half of the 19th century, and the f .....

.... and national parks. It is now strictly protected. Some males occupy a territory of 200 square miles. When there is enough food, the tiger lives in a much smaller territorty. It lives in the forest, the grassland, or the swamps. The tiger attacks a variety of prey, mainly deer, antelopes, pigs and buffalo. Once in awhile, it will attack cattle and even humans. There are many stories about the evils done by "man-eating" tigers. They're usually old tigers that are sick or wounded, and cannot hunt normally. The destruction of their usual prey may also cause them to attack humans. As soon as the tiger spots prey, it begins a slow and silent approach. When it is ne .....

.... to Environmental Protection Agency (EPA) data, in 1994 and 1995, 45 million Americans drank water from water systems that fell short of SDWA standards.[1] Adding gravity to the situation, the Centers for Disease Control (CDC) and the EPA advised that people with weakened immune systems should consult with their doctors and consider boiling their drinking water to kill any cryptosporidium.[2] This is just the tip of the iceberg. Some scientists believe that for every outbreak reported in the United States, another ten may be occurring.[3] One such study found that as many as one in three gastrointestinal illnesses — often chalked up to "stomach flu" — are ca .....

.... begins in infancy and is characterized by chronic respiratory infection, pancreatic insufficiency, and increased electrolytes in sweat (Shwachman, 1997). The abnormal gene, which causes an increased presence of chlorine within the exocrine cells, was identified in 1989 and is known as transmembrane conductance regulator (CFTR) (Hopkin, 1998). is the most common genetic disorder in the white population (Hopkin, 1998). Almost every article or book about begins with a statement similar to the one above. People who have genetic disorders are born with them. The inherited genetic defect causes a chemical error in all the cells in their body (Silverstein, 1994; .....

.... condition is real, yet both sides both have their cases. can be created by mere wisps of suggestion. Bits and pieces of an experience are parcelled out to different regions of the brain, memories then settle in the auditory cortex, and memories of its appearance into the visual cortex. Its here in the limbic system they assemble all these memories, gathering them into a cohesive whole. False memories are also commonly in the con drum called "source amnesia". Thanks to the brain's frontal lobes, most people can distinguish the memory of a dream and a real life event. But if the frontal lobes are damaged, people cannot remember where a memory came from. T .....

.... been in use for over 50 years it was basically another weapon of destruction. Since there was no war, the scientists who created the atomic bomb, turned this destructive power into huge plants generating "clean and cheap "electricity for the country. But this new resource brought sickness, mutations, cancer and eventually death to those exposed to high levels of radiation. Even the government declared that nuclear powers were safe and efficient. The truth is that accidents do happen at nuclear power plants and at other facilities all the time. An accident at a nuclear power plant has the potential to be much more harmful than an accident at a coal or gas .....
