An end to genetic diseases
An end to genetic diseases The United States has a very diverse heritage. There is no "American" race. Americans are the blending of many cultures throughout many generations. With this blending of cultures comes a blending of genes. In the past, genes have not been well understood. They were not understood until Mendel did experiments on plants to find out why different plants of the same species had different characteristics. His goal was to find the key to unlock the mystery of inhe...

Alternative Medicine
Alternative Medicine The health care industry has a variety of policies and standards regarding coverages for alternative medicine modalities. From a sociological standpoint, unconventional, alternative, or unorthodox therapies refer to medical practices that are not in conformity with the standards of the medical community. The New England Journal of Medicine defines unconventional therapies, �as medical interventions not taught widely at U.S. medical schools or generally a...
Alternative energy sources
Alternative energy sources Alternative Energy Sources In the not-too-distant future -- with regard to history's timeline -- there will come a point when fossil fuels will have been depleted and humans will be forced to find alternative sources with which to power automobiles, household heating units and myriad other machinery that utilizes fuel. However, waiting until supplies are exhausted before establishing a workable alternative would place a major hardship upon future energy demands....
Alternative energy
Alternative energy SOLAR ENERGY -- THE ENERGY OF THE FUTURE? About 47 per cent of the energy that the sun releases to the earth actually reaches the ground. About a third is reflected directly back into space by the atmosphere. The time in which solar energy is available, is also the time we least need it least - daytime. Because the sun's energy cannot be stored for use another time, we need to convert the suns energy into an energy that can be stored. One possible method of storing s...
Alternative fuel source
Alternative fuel source In one year, America will have exhausted 80% of her petroleum reserves. Will we then go to war with the Arabs for the privilege of driving our cars? Will we strip-mine our land for coal and poison the air we breathe to drive our autos an additional 100 years? Will we raze our forests for our energy needs? I certainly hope our country will never come to those conclusions. However, someone must make a conclusion � hopefully toward an alternate fuel source. The f...
Alternativly powered cars
Alternativly powered cars The current vehicles that are powered by gasoline pollute, but as technologies improve and the human way of life changes alternatively powered vehicles enter the automotive industry. These vehicles developed to achieve better gas mileage and to help slow the production of the gasses that cause Global Warming. The hybrid vehicle is one of the newest and most popular alternatively powered vehicle. According to "Future Cars", a Learning Channel Documentary, two moto...
Alcoholism and Drug Abuse
Alcoholism and Drug Abuse A drug is a chemical that interacts with other substances to alter or change something. In the United States, drugs are a major part of everyday life. Whenever you have a cup of coffee, drink tea, or flavor something with condiments such as sugar or salt, you are using drugs. In some instances they may be used for positive effects ( aspirin or prescription pain killers in moderation to cure a headache or other sickness). However, sometimes people abuse drugs (alcoho...

Some are easily treatable and others can be terminal, but some of the worst are those that still remain without a cure; one such disease is amyotrophic lateral sclerosis. Amyotrophic lateral sclerosis, or ALS, is a degenerative disease affecting the human nervous system. It is a deadly disease that cripples and kills its victims due to a breakdown in the body...
Alternate energy sources
Alternate energy sources Alternate Energy Resources As most people know our energy supply is slowly running out. We are using energy sources that either pollute the air, take up natural resources or cause damage to other forms of life. Today, we are working on other forms of energy that do not pollute or cause harm to the environment. Here are some: Magnetohydrobynamic Power Magnetohydrobynamic power is where created by plasma. One way is for gases are heated to really hi...

Alcoholism 2 Alcoholism Alcoholism, chronic and usually progressive illness involving the excessive inappropriate ingestion of ethyl alcohol, whether in the form of familiar alcoholic beverages or as a constituent of other substances. Alcoholism is thought to arise from a combination of a wide range of physiological, psychological, social, and genetic factors. It is characterized by an emotional and often physical dependence on alcohol, and it frequently leads to brain damage or early ...
Alcoholism 3
Alcoholism 3 Alcohol consumption Alcohol, probably the oldest drug known, has been used at least since the earliest societies for which records exist. Of the numerous types of alcohol, ethyl alcohol is the type consumed in drinking. In its pure form it is a clear substance with little odor. People drink alcohol in three main kinds of beverages: BEERS, which are made from grain through brewing and fermentation and contain from 3% to 8% alcohol; WINES, which are fermented from fruits such as g...
Alcoholism 4
Alcoholism 4 "Alcohol is a socially acceptable, legal drug that is consumed by the majority of Americans without problems to themselves or others (Milgram xiii)." Misuse of alcohol can lead to alcoholism, one of the most widespread and complex problems in America. The reasons some people become dependent on alcohol and others do not are unknown. Many health problems are associated with chronic alcohol abuse, including damage to the liver, brain, or central nervous system. Alcohol ...

Alcoholism is a term that is widely recognized throughout the United States and the World. Alcoholism is a chronic disease, progressive and often fatal; it is a disorder and not due to other diseases or emotional problems. Many scientists have tried to define what Alcoholism is, and what this disease may ...
Alchemy
Alchemy Science Alchemy Alchemy, ancient art practiced especially in the Middle Ages, devoted chiefly to discovering a substance that would transmute the more common metals into gold or silver and to finding a means of indefinitely prolonging human life. Although its purposes and techniques were dubious and often illusory, alchemy was in many ways the predecessor of modern science, especially the science of chemistry. The birthplace of alchemy was ancient Egypt, where, in Alexandria, it bega...
Alcohol 2
Alcohol 2 A class is chemical compounds, all if which consists of chemically bonded atoms of carbon, hydrogen, and oxygen all alcohol molecules contain at least one hydroxyl group. When people say alcohol they usually think of beer, wine, or liquor, but there are several types of alcohol. An alcoholic beverage is a drink that contains ethyl alcohol. They are mostly made of grains or from grapes or other fruits. There are two main groups fermented and distilled drinks. Fermented drinks con...
Alcohol benefits
Alcohol benefits Can you get the health benefits of wine without the alcohol? Red wine is making a lot of news lately for its positive benefits on heart health. Doctors believe it may even be responsible for the so-called French paradox -- people in France eat high-fat diets, but have lower rates of heart disease than Americans do. One reason red wine seems to have beneficial effects is that it contains chemicals called flavonoids, which appear to help prevent heart disease. Researchers i...
Alcohol
Alcohol "It discloses secrets; ratifies and confirms our hopes; thrusts the coward forth to battle; eases the anxious mind of its burthen; instructs in arts. Whom has not a cheerful glass made eloquent! Whom not quite free and easy from pinching poverty!" (Horace first century B.C.) Initially, I wanted to write this paper on substance related disorders. However, in reading the text I felt compelled to focus on the psycological effects and problems that are related to alcoholism...
Air pollution
Air pollution AIR POLUTION Problem: The first thing people see, in the morning, when they walk outside is the sky or the colored sun. Is this world giving us the privilege of seeing the natural colors of the sun through all the layers of pollution within the air (Dinanike 31)? Not only are beautiful sights such as this hidden behind the pollution this world causes everyday, but an increase in diseases, infections and death occurs. What causes pollution? What can we do to prevent i...
Albert Einstein 2
Albert Einstein 2 Albert Einstein was on of the most popular men of all time. When one thinks of Einstein, they think "scientist," or maybe, "genius." Well he was both of those, but not only those. Einstein was a meek man, an ingenious man also, a man that could invent any-thing in the world if he wanted to, but kept his ideas very normal and simple. Einstein was a very meek man in that he did not want popularity; he just wanted to be normal, just like everyone else. For example, at th...
Albinism
Albinism Albinism ALBINISM Albinism. The word albinism refers to a group of inherited conditions. People with albinism have little or no pigment in their eyes, skin, or hair. Recently a test has been developed to identify carriers of the gene for ty-neg albinism and for other types in which the tyrosianase enzyme does not function. The test uses a sample of blood to identify the gene for the tryrosinase enzymes by its code in DNA. The above test does not apply to to one type of albinis...
