.... make more money on their products. About 70% of genetic engineering falls into this category. A second example is biowarfare. Perhaps some of you saw the recent New Yorker article on the subject [Richard Preston, "Annals of Warfare: the Bioweaponeers." New Yorker, March, 1998]. There is widespread consensus that the information reported in that article is true. One of the things he mentions is that the former Soviet Union had the largest big-warfare program in the world, with 32,000 scientists working on it. Much of it had to do with genetic engineering. In one of the projects they took smallpox, which has otherwise disappeared from the world, and fo .....

.... scientists are concerned that changes in the variable contents of the atmosphere (particularly changes caused by human activities) could cause the Earth's surface to warm up to a dangerous degree. Even a limited rise in average surface temperature might lead to at least partial melting of the polar ice caps and hence a major rise in sea level, along with other severe environmental agitation. An example of a runaway greenhouse effect is Earth's near-twin planetary neighbor Venus. Because of Venus's thick CO2 atmosphere, the planet's cloud-covered surface is hot enough to melt lead. Water vapor is an important "greenhouse" gas. It is a m .....

.... cities allows surface temperatures to rise higher than in rural areas. Additional city heat is given off by vehicles and factories, as well as by industrial and domestic heating and cooling units. At night, the solar energy, which is stored as vast quantities of heat in city buildings and roads, is released slowly into the city. The dissipation of heat energy is slowed and even stopped by the tall building walls that do not allow infrared radiation to escape as readily as do the relative level surfaces of the surrounding countryside. The slow release of heat tends to keep city temperatures higher than those of the unpaved faster cooling areas. On clear, s .....

.... be able to deal with the situation effectively you have to acquire information and learn the good and the bad that come with having a premature infant. When a baby is born prematurely there are a number of tests that the baby has to go through. First the doctors and nurses have to assess the baby’s heart, lungs, color and temperature. If the baby is having trouble with any of these things then it is taken into what is called the neonatal intensive care unit. In some of the smaller hospitals they aren’t equipped with the technology that is needed to keep the baby alive and the baby has to be transported to a bigger hospital, usually to a hospital in a metropo .....

.... the ways of past societies. While the artifacts uncovered can be helpful in painting a picture of what the lives of past civilizations were like, the act of digging up such artifacts can be considered immoral. A person claiming to be conducting an archeological study in a present-day cemetery would most definitely be apprehended and punished for his actions. Cemeteries are considered sacred places, and those who violate the laws made to protect them will be punished for their actions. There is no difference between the aforementioned act and that of unearthing sacred Native American burial grounds, for example. Great care was taken to ensure that t .....

.... America, which span all economic groups. Exercise is another important factor. The more exercise people get the lower the risk of heart disease. Part of the reason for this is the fact that people that exercise tend to have more healthy lifestyles, which include lower levels of alcohol use and lower fat diets. My stepfather had coronary heart disease. He talked about it freely before he passed away. Over the course of 10 years he had two triple bypass surgeries. He believed he contracted the disease due to poor diet, smoking and a family history of the disease. Throughout the entire time his outlook remained very positive. There were several dramatic changes t .....

.... but it has more pronounced effects on the central nervous system. Like amphetamines, they causes increased activity, decreased appetite, and a general sense of well being, which can last 6 to 8 hours. After the initial rush, there is typically a state of high agitation that in some individuals can lead to violent behavior. Contrary to the stereotype of rural areas as idyllic, protected environments in which to raise families, substance abuse is as great a problem as it is in the cities. One must realize that rural communities vary in characteristics considerably, which complicates our understanding of rural substance use problems and increases the .....

.... love the irony -- I've spent over 400 hours of my life looking for comets, and haven't found anything, and now, suddenly, when I'm not looking for one, I get one dumped in my lap. I had obtained an observation of P/Clark earlier, and needed to wait an hour or so before P/d'Arrest got high enough to look at, and was just passing the time til then, and I decided to look at some deep-sky objects in Sagittarius. When I turned to M70, I saw a fuzzy object in the same field, and almost immediately suspected a comet, since I had been looking at M70 last month, and *knew* there wasn't any other objects there." Thomas Bopp explains his story like this, "On the night o .....
