.... poverty, we may end up looking back nostalgically on the late twentieth century as a time of health and tranquility. As we show you, in the world of viruses, we are the invaders (Baddorf, Ourworld.compuserve.com)." Between the years of 425BC-430BC Athens' population was dramatically reduced when about 300,00 of its inhabitants died from some sickness. Some people now believe that this great plague was really Ebola. The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire, in 1976. The doctors didn't know how to treat it and that meant that they didn't know how to contain it either. As infected people met in public places the virus spread. In ....

.... of the United States congress. Genetic engineering is a safe and powerful tool that will yield unprecedented results, specifically in the field of medicine. It will usher in a world where gene defects, bacterial disease, and even aging are a thing of the past. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted. The first step to understanding genetic engineering, and embracing its possibilities for society, is to obtain a rough knowledge base of its history and method. The basis for altering the evol ....

.... the body is called the alimentary canal. Just as canals are constructed to guide ships through waterways to their destinations, the alimentary canal guides food as it travels through the human body. The whole canal is lined with a mucous membrane. Digestion begins in the mouth. Here the food is cut and chopped by the teeth. The tongue helps mix the food particles with a digestive juice called saliva, which is secreted in the mouth. Saliva moistens the food so it can be swallowed easily. It also changes some starches into simple sugars. It is important to chew food thoroughly to mix it well with saliva. Thorough chewing cuts food into small pieces that are more eas ....

The belts extend more than two million kilometers from the center of and even farther in the direction away from ....

.... two solar panels with it; a piece of the shield wrapped around the other panel keeping it from deploying. Skylab was maneuvered so its Apollo Telescope Mount (ATM) solar panels faced the Sun to provide as much electricity as possible. Because of the loss of the meteoroid shield, however, this positioning caused workshop temperatures to rise to 126 degrees F. The launch of Skylab 2 was postponed 10 days while NASA engineers developed procedures and trained the crew to make the workshop habitable. At the same time, engineers "rolled" Skylab to lower the temperature of the workshop. Skylab's 2nd manned mission - May 25th to June 22nd Astronauts; Charles Conrad, Jr. ....

.... When a muscle has no nourishment, it "Atrophies" or wastes away. "Lateral" identifies the areas in a person's spinal cord where portions of the nerve cells that nourish the muscles are located. As this area degenerates it leads to scarring or hardening ("Sclerosis") in the region. Over 5,000 Americans are diagnosed with ALS each year. There is great variation in the course of the disease. Symptoms usually appear in individuals between the ages of 40-70, though the disease has been reported in both younger and older persons. Survival after the confirming diagnosis is, on average, two to five years. Progression of ALS varies with each individual; therefore, some will live lon ....

.... named Megalosaurus. Thousands of specimens have since been discovered nearly worldwide. Different types of dinosaurs varied greatly in form and size, and they were adapted for diverse habitats. Their means of survival can only be identified from their fossil remains, and some identifications are in dispute. They ranged in weight from 4 to 6 lb., in the case of the compsognathus, and up to 160,000 lb., in the case of the brachiosaurus. Most dinosaurs were large, weighing more than 1,100 lb., and few weighed less than 100 lb. Most were herbivores, but some saurischians were carnivorous. The majority were four- footed but some ornithischians and all carnivores walked ....
