.... have slowly evolved and disappeared throughout geological time because of climate changes and the inability to adapt to survive competition and predation. Since the 1600's, however, the rate of extinction has accelerated rapidly because of human population growth and resource consumption (17). Today, most of the world's habitats are changing faster than most species can adapt to such changes through evolution, or natural selection. The current global extinction rate is estimated at about 20,000 species per year, exponentially greater than the background extinction rate (17). Many biologists believe that we are in the middle of the greatest mass extinction episode since ....

.... a flat road and forgets to put the vehicle into park. The car should stay in that spot. This state of being is called inertia. All of a sudden the wind picks up or some kid crashes into the car with a bike. Both the wind and the kid's bike crashing into the bike are unbalanced forces. The car should start to move. The car might accelerate to two miles per hour. Now we would all assume that the car would come to a stop sometime. We assume this because it is true. It is true because there is friction between the tires and the road. The car now has inertia in uniform motion. Since there is friction, the car cannot keep moving forever because friction is an unbalanced ....

.... analyze the genetic make-up of cells, and will soon render traditional pharmaceutical research obsolete. This allows for whole new generations of drugs that will be made to combat diseases by effecting changes in a their specific genetic design. PROBLEM STATEMENT Currently the pharmaceutical industry is a very high risk industry in which fewer than one in ten promising drug products ever makes it through the testing phase and onto the shelves at the local pharmacy. The effect is that the production of a new drug is almost like a guessing game that may or may not produce any profit. A Company may have a long list of chemicals that could make possible drugs to tre ....

.... obvious capabilities-e-mail, newsgroups, Web sites, and a modest amount of actual market transactions-it remains uncertain what business models and Internet functions will prove most popular and profitable over the long term. Much will depend upon how the new electronic technologies will change existing business practices, market structures, and the social habits of the workplace, marketplace, and home. Can we discern how electronic commerce adds value to conventional marketplace transactions, making the Internet a preferred venue for business? Will markets of the future be substantially more efficient, to the extent of being "friction-free?" Or will a new regime of dom ....

.... Teams from universities successfully inserted instructions for building an anti-fluorescein antibody in the DNA of bacteria. This antibody binds with fluorescein molecules. Into this chunk of material, they inserted instructions for buildin g a metal-ion binding sight. They discovered where to put this slot by simulating the antibody on a large computer. The resulting product revealed an anti-fluorescein antibody which binds to metal ions. After physically inserting the genetic code in to E. coli. bacteria, the researchers had a large batch of a new compound which they named QM212. When copper was added to this new batch, it binded with the metal-ion binding sight, decrea ....

.... to maintain. Neurotransmitters are chemicals that nerve cells (neurons) use to communicate messages to each other. Receptors are special areas that receive these chemical messages. The key neurotransmitter in migraine is called serotonin (often referred to in the scientific literature as 5-HT or 5-hydroxytryptophan). If something interferes with the normal functioning (production, release, receptor docking, and/or re-uptake) of serotonin, that disrupts the normal functioning of the nervous system and can lead to various symptoms associated with migraine. The severe pain associated with migraine occurs when the mechanism that normally inhibits and/or mediates pain is d ....

.... virus that was quickly found to be carried through field mice. The natural territory of this virus included parts of Japan, Korea, northeastern China, and southeastern and central Russia. Between 1955 and 1977, this virus caused many more infections along with fatalities. Throughout the 1970s, eleven other strains of es were found in Korea and Eurasia. In 1976, Hantaan virus was isolated from the Apodemus agreavius coreae mouse. Using the microscope, one could see the round microbes that were stacked in rows along the epithelial lining of the lungs (CDC website 6). Each infection still involved mild kidney infections. The same type of rodent always carried the virus ....

.... the is not something to be put aside, yet rather something to be worked on and studied. "The displays that nature is not immune to our presence" (Kralijic, 1992). Ways must be found to lessen the threat of this growing crisis. If this effect were to continue and grow, the earth’s population would be exposed to serious threats. Carbon dioxide is essential for plants who use it for photosynthesis, yet too much can lead to serious threats. The problem lies in the disruption of the balance between how much carbon dioxide plants intake, and what our population produces. If this natural filtering process is unbalanced, the atmosphere will receive too much carbon dioxide and o ....
