    1,035 words
    The movie A Civil Action brings up an interesting idea that many people in the public don't see or hear about very often. The idea that the big corporations often don't take into account the safety of the people that work for them or the people that live around the factories. These big corporations are run entirely by money and the idea of what things will cost and how much money they can possibly make.

  • Patients With Als Fact That Glutamate Skin

    This theory is based on the fact that glutamate, an amino acid present in proteins, can cause neuronal cell death when present in high concentration.

In addition, there is a decreased ability of glutamate to be taken up in fractions...

    Cleaning Up after the Exxon Valdez Was A Mistake Through many hours of research I have determined that the spill cleaning techniques used to clean the Prince William Sound area of Alaska did more harm than leaving the oil where it was.
