Although widely unknown to the American public, many of America's waterways are in extreme danger from something besides pollution. A new organism has been introduced that has the possibility to be deadlier than any pollution imaginable. This new threat is the zebra mussel (Dreissena polymorpha). A zebra mussel is a fresh water mussel that filters every bacteria in a water system until there is nothing left, including the zebra mussel. This can swiftly cripple any body of water. Z

Biological Warfare The history of Biological Warfare(BW), like most topics, can be divided into 3 parts: Early History, Modern History, and what we call "The Now." The early history starts as far back as you can think and continues up to the start of the 20th century. The first recorded use of biological agents is the Romans using dead animals to foul the enemies water supply. This had the dual effects of decreasing enemy numbers and lowering morale. The idea behind this kind of attack

The Prairie Dog Cynomys ludovicianus, known more commonly as the prairie dog, has more traditionally been viewed as the pariah of the prairie. However within the last year, attention has been drawn to these furry little rodents. They are extremely unpopular-¬Ěso much so that for decades the Federal Government has tried desperately to eliminate them. What the government doesn't know is that these creatures are vital to the survival and thriving of several species, and are in fact an asset t

Spinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray

It is my opinion that Biometrics is an idea that should not become a reality due to the lack of privacy and control over our own lives that it would create. If the government were to carry out with the plan of Biometrics then the world would become more of a paranoid place then it already is. The general public would be able to be tracked at any moment and all the information about each individual would be accessible at the touch of a button. Our entire medical record

Rays are primarily slow-moving, bottom-dwelling fishes of the oceans, the rays are close relatives of the sharks. Both, including skates, belong to the same class of fish, Chondrichthyes-vertebrates whose skeleton is composed of cartilage, not true bone. The terms skate and ray are often used interchangeably. Both fishes belong to the taxonomic order Batoidei, but the skates are classified in the separate suborder Rajoidei. Skates and rays occur in nearly all the oceans of the world, from shallo

DIABETES Diabetes is a chronic illness but it is not fatal. A chronic illness is classified as an illness with no cure and has symptoms that persist over a long period of time. Diabetes is not a fatal illness, except in a few rare and severe cases. It is one of the most common chronic illnesses that a person can get. About 16 million Americans have diabetes and diabetes is most common in Hispanics and native Americans. About 5% (800,000) have type I which only occurs in young people. People

Klyment Tan March 2, 1998 Ozone in Medicine: Modern Magic Bullet or Fatal Deception? Ozone may be one of the most misunderstood medical achievements of this century. In this essay, facts will be filtered from politics to find the answer to this question: Ozone-the modern magic bullet or fatal deception? First of all, what is ozone? As defined in the Encarta Encyclopedia: Ozone (Greek ozein, "to smell"), allotropic form of oxygen having three atoms in each molecule, formula O3. It is a
