euthenasia The Issue of Human Cloning The recent news of the successful cloning of an adult sheep-in which the sheep\'s DNA was inserted into an unfertilized sheep egg to produce a lamb with identical DNA-has generated an outpouring of ethical concerns. These concerns are not about Dolly, the now famous sheep, nor even about the considerable impact cloning may have on the animal breeding industry, but rather about the possibility of cloning humans. For the most part, however, the ethical concern
evolution creationism Looking For A Term Paper? Try This Site Too! Creationism vs. Evolution In my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of
exxon valdez INTRODUCTION On March 24, 1989 at 4 minutes past midnight, the oil tanker ExxonValdez struck a reef in Alaska\'s breath-taking Prince William Sound. Instantaneously, the quiet waters of the sound became a sea of black. "We\'ve fetched up - ah - hard aground north of Goose Island off Bligh Reef, and - ah - evidently leaking some oil," Joseph Hazelwood, captain of the ship, radioed the Coast Guard Marine Safety Office back in Valdez. That "some oil" turned out to be a total of 11,000,
fetal alcohol syndrome On any given day in the United States... 10,657 babies are born. (US Census Bureau). Twenty of these babies are born with Fetal Alcohol Syndrome. Twenty may seem as though it is not a lot, but when you compare it to the fact that this number is more than HIV positive, Muscular Dystrophy, Spina Bifida and Down Syndrome combine it creates a whole new parameter. Fetal Alcohol Syndrome is a direct result of a woman’s competed disregard for the fetus. Fetal Alcohol Syndrome (FA
Forensics Forensics is defined as the aplication of science to interpret clues for crime investigation. The earliest forensic scientists were physicianswho were called upon to give an opinion as to the cause of death in individuals. Now most of the forensic scientists are investigators that pick up clues at the crim scene. Because criminals often are not the brightest people on the planet they often do not plan out a burglary or theft and carelessly leave behind distict clues that allow an invet
Genetic Engineering The Frontier Genetic Engineering: The Frontier Science is a still somewhat obscure creature that continues to evolve, radically changing the face of mankind perhaps faster than it’s creator. The magnificent world of science has witnessed many profound breakthroughs and advances in this past century, but none as noteworthy as genetic engineering. As a subset of the more general subject of biotechnology, genetic engineering is “the process of altering genetic material by purpos

Green Sea Turtle Green Turtle Introduction The Green Turtle (Chelonia mydas) is one of the many species of turtles that inhabits the vast oceans. The green turtle is named for the greenish color of it’s fat found under its shell. It is a large, heavy reptile, usually about 0.7-1.0 m in shell length and about 90-140 kg in weight. The maximum length and weight are about 1.2 m and 375 kg respectively. (1) The green turtles upper shell is smooth and wide, the animal is brown, but when the light from
History of Chemistry History of Chemistry Introduction: Humans have always been very curios creatures. The have always wondered about what they are and why they are here. Our limited knowledge of the environment has always urged for new things to be discovered. The desire to understand the world better has made people search for rational answers, for principles and laws. For centuries people have tried to unlock the mysterious world that surrounds them. History: Because myths did not explain thi
Human Cloning2 I have observed in my nineteen years of living that almost everyone in this society strives to be the same or like the popular culture. The average person is very materialistic, and strives for an appealing physical appearance. Artificiality is common in the popular culture. For example, dying of hair color, inserting color contacts, getting lyposuction, implants or removal of flaws on the body is prevalent. I strongly oppose human cloning primarily because I believe that humans a
Human Evolution Human evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens, meaning “wise man.” Since at least the Upper Paleolithic era, some 40,000 years ago, every human society has devised a creation myth to explain how humans came to be. Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from. The science of paleoanthropology, which also tries to create

Human Genome Project What is the Human Genome Project? The Human Genome Project (HGP) is an international research program designed to construct detailed genetic and physical maps of the human genome, to determine the complete nucleotide sequence of human DNA, to localize the estimated 80,000 genes within the human genome, and to perform similar analyses on the genomes of several other organisms used extensively in research laboratories as model systems. This project is estimated to take 15 year
Hydrothermal Vents Imagine being on the ocean floor. You are in total darkness and in unbearable pressure. You would think that in this freezing environment there is no life, but there is. Eight years ago something was discovered that no one could even imagine. It was a source of life called a hydrothermal vent. A hydrothermal vent is a hot spring found at depths from three to four thousand meters in areas along mid-ocean ridges. Plate movements occurring on the earth’s crust create vents. They
Immunology of Aids The Immunology of Aids Introduction Although HIV was first identified in 1983, studies of previously stored blood samples indicate that the virus entered the U.S. population sometime in the late 1970s. Worldwide, an estimated 27.9 million people had become HIV-infected through mid-1996, and 7.7 million had developed AIDS, according to the World Health Organization (WHO). AIDS is a disease of the immune system, and is caused by Human Immuno deficiency Virus (HIV). HIV targets a
Is Carbon Dating Accurate Is carbon dating accurate? Carbon dating, used since 1948, is currently the main method of testing artifacts for age. My objective through this essay is to disprove the accuracy of the Carbon 14 dating method. William Libby invented carbon dating in 1948. It works on the principle that the carbon 14-C, is radioactive. It decays at a “known” rate called a half-life. This is balanced by the fact that 14-C is constantly produced in atmospheric reactions. Because of this, 1
Is there a good side to human cloning Technology is changing the world as we know it. Not all of these advances in technology are viewed as positive. One of the breakthroughs that has received mixed responses is the issue of cloning. There has been much debate on this topic, and the debate is certain to rage on for many years to come. You may be asking yourself: What is cloning? How can I benefit from cloning? Is cloning legal? Why should we clone human beings? What is the world community doing
Kudzu Kudzu is a major threat to Michigan. In this report I will discuss many factors as to why kudzu is a threat, and what we as a state can do about it. The reason I chose this topic was that I have lived in the south for most of my life, and have seen the effects of Kudzu. This plant is very threatening to us agriculturally as well as economically, and we need to deal with this problem now, before it spreads up into the beautiful landscape of Michigan. Kudzu is a climbing, semi-woody, perenni
Life Science and the Law One issue that has been a controversy is the preservation of endangered species. Ever since the 1960\'s, scientists have been fighting for laws and acts to protect animals and plants in keeping them in good health and their populations high in numbers. The problem is animals and plants are having trouble surviving in today\'s world which leads them to be classified as endangered or threatened. Endangered, meaning animals or plants with little population that the species
mad cow Who would of thought that eating hamburgers, steaks and drinking milk could produce an epidemic disease? These types of food are frequently eaten for their appealing tastes and nutritional values. The discovery of Creutzfeld Jakob Disease (CJD) has been a long and remarkable one. The cause of this disease is a mutated prion protein within the brain that can be either inherited or acquired. These mutations create sponge like holes that destroy the brain. As a result, the disorder gives bo
Music Therapy Music Therapy Music therapy is the prescribed use of music and musical interventions in order to restore, maintain, and improve emotional, physical, physiological, and spiritual health and well-being (Lindberg). So one finds the selections under the New Age/Relaxation section of the record store about as relaxing as water torture? Just because one\'s taste runs more to Sousa than to soothing doesn\'t mean one can\'t reap all these relaxation benefits music is supposed to have. Musi
NANOTECHNOLOGY What is Nanotechnology? Computers reproduce information at almost no cost. A push is well underway to invent devices that manufacture at almost no cost, by treating atoms discretely, like computers treat bits of information. This would allow automatic construction of consumer goods without traditional labor, like a Xerox machine produces unlimited copies without a human retyping the original information. Electronics is fueled by miniaturization. Working smaller has led to the tool

Never Met A Dull Enzyne “ Never Met A Dull Enzyme” A. Personal Information Arthur Kornberg (1918-), American biochemist and physician, claims he has never met “a dull enzyme.” He has devoted his life to pursuing and purifying these critical protein molecules. His love of science did not spring from a family history rooted in science. He was born on March 3rd, 1918, the son of a sewing machine operator in the sweatshops of the Lower East Side of New York City. His parents, Joseph Aaron Kornberg a
None Provided14 Should Human Cloning Be Permitted? For years, part of the American public, and humans in general, have been fascinated with the possibility of creating human life by other than natural means. There are many that strongly disagree with the idea of human cloning. It certainly wasn\'t surprising when they were able to clone a sheep or a pig, and will not be surprising if someday scientists will be able to clone a human being. Should cloning for human benefits or even human cloning i
origin of life To help us with our study of origins, we will use two main sources: the Bible – as God’s direct revelation of life, and science – a way to interpret the Bible using scientific knowledge. In his book Biology Through the Eyes of Faith, R.T. Wright (1989) states: “It is an important conclusion of faith that both science and Scripture are sources of knowledge of God’s works and that, when properly understood, should not lead to conflicts.” I agree with this statement, believing that G

oxygen Oxygen is one of the 92 known elements. An element is a substance that cannot be decomposed into a simpler substance by any simple means. Each of the 92 naturally occurring elements are therefore one of the fundamental materials from which everything in the Universe is made. The History of Oxygen On August 1,1774, Joseph Priestley examined the effect of intense heat on mercuric oxide. He noted that an air or gas was readily expelled from the specimen. To his surprise a candle burned in th
Pain Vaccine Could Protect Against Stroke And Epilepsy Damage February 25, 2000 A new oral vaccine has offered new hope because of its effectiveness in protecting laboratory rats against brain damage from epilepsy and stroke, and might one day be used to help humans with the same conditions. The vaccine blocks a protein in the brain called NMDA, but does so only when epilepsy or stroke occur. The vaccine is released in the brain as needed and is protected from any side effects. During and collea
Pasteur PASTEUR, Louis (1822-95). The French chemist Louis Pasteur devoted his life to solving practical problems of industry, agriculture, and medicine. His discoveries have saved countless lives and created new wealth for the world. Among his discoveries are the pasteurization process and ways of preventing silkworm diseases, anthrax, chicken cholera, and rabies. *BR* Pasteur sought no profits from his discoveries, and he supported his family on his professor\'s salary or on a modest governmen
PCBs PCBs: Polychlorinated Biphenyls Polychlorinated biphenyls are a family of man-made chemicals that contain two hundred and nine individual compounds with varying toxicity. Many different combinations are possible. In chemical terminology, “phenyl” denotes a ring structure of six carbon atoms attached to something else; “biphenyl” results when two such rings are attached to each other. Polychlorinated biphenyl (PCB) is any molecule having multiple chlorine atoms attached to the carbon atoms o
placebos Why we need placebos English/ History By Jj wallis A placebo is defined as an inactive substance resembling a medication, given for psychological effect or as a control in evaluating a medicine believed to be active. However the placebo only fits this description under the restraints it has been given by the U.S. Food and Drug Administration, which refers to the placebo as an investigational new drug. In actuality, up until the present much of medicine was built on placebos. "Not very l
reproductive technology Reproductive Technology By: Jeff Stott Technological development and the advancement of science constantly raises new political and legal challenges. We must promote scientific development, but at the same time we must also impose restrictions involving certain human and social values. Reproductive technology is one of the best examples of the challenges posed by the development of medical science and it’s involvement with the law. Issues involved with Reproductive Techno
Rocks and Minerals According to Webster’s Dictionary, the definition of a mineral is an inorganic substance. Citrine is one of the most popular minerals. It is a variety of quartz. Citrine is a yellowish-orange mineral. Citrine is a very popular gemstone because it is very affordable and very pretty. Along with topaz, citrine is the birthstone for the month of November and the anniversary gemstone for the 17th year of marriage (www.jewelrymall.com). Citrine is also considered a symbol of hope, y

SEDIMENTARY ROCKS, are Rocks that are formed by the compaction of sediments or by the crystallization of the dissolved minerals. Quartz is the most abundant mineral in the Earth\'s crust. Quartz has been found in meteorites and in some rocks collected on the moon. Quartz has the chemical formula
Sources of Energy Sources of Energy Have you ever thought about how we get the energy to run the things we take for granite every single day. There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability of energy in useful forms. The seven main energy sources are fossil fuels, hydroelectric, solar power, win power, geothermal, nuclear power, and b
starch STARCH Starch is a white, granular, organic chemical that is produced by all green plants. Starch is a soft, white, tasteless powder that is insoluble in cold water, alcohol, or other solvents. The basic chemical formula of the starch molecule is (C6H10O5)n. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form. Starch is manufactured in the green leaves of plants from excess glucose produced during photosynthesis and serves the plant as a reserve foo
the ethics of cloning “To Clone, Or Not To Clone?” Did you ever imagine having a child that is the exact replica of you? Did you ever imagine of having the cure for heart disease or cancer? Well, these fantasies are not far from reach. The way we could reach these fantasies is through a process called cloning. Cloning is topic with which there is heated debate, and one that I feel that can be used for the better of all man kind. In this essay I will outline some of the key arguments and counter
The Hot Zone Section II: Summary “ We don’t really know what Ebola has done in the past, and we don’t know what it might do in the future.” (p.49) According to Eugene Johnson, a civilian virus hunter, specializing in Ebola, the essence of the virus itself is one whose existence is still unintelligible to humans. The knowledge of the nature of this virus, as well as Marburg the “gentle sister” of the three filovirus sisters (Ebola Zaire, Ebola Sudan, and Marburg), remains questionable today. In h
The Poisoning of Our Ozone The Poisoning of Our Ozone Layer The poisoning of the Earth’s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone’s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications
The Selfish Gene In the popular science book, The Selfish Gene, Richard Dawkins explains his theory of evolution, and its occurrence for the good of the gene rather than the good of the species or individual. Dawkins believes the gene to be practically immortal, carrying on generation upon generation. By calling them “selfish” Dawkins describes a genes’ strategy of competition for survival, its tendency to behave in a manor suited to ensure its propagation. “Genes are competing directly with the
