Rachel Carson Through the Years Rachel Carson Rachel Carson is considered one of America\'s finest science and nature writers. She is best known for her 1962 book, Silent Spring, which is often credited with beginning the environmental movement in the United States. The book focussed on the uncontrolled and often indiscriminate use of pesticides, especially dichlorodiphenyltrichloroethane (commonly known as DDT), and the irreparable environmental damage caused by these chemicals.

Sexual reproduction takes place when two organisms get to gather and exchange DNA, an example of this is frogs mating. Asexual reproduction only requires one organism to reproduce, an example of this could be Cell Division. One major difference between these to modes of reproduction is the need

Robert\'s father Arthur died in October of 1918, at an early age of only thirty-three years old.

The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body\'s ability to provide adequat

Schizophrenia When a person hears the word crazy, their first thoughts are probably of symptoms of schizophrenia. Schizophrenia is seen as the ideal case of insanity. The causes of this disease remain unknown, but scientists are constantly searching for answers. Although a cure for schizophrenia is surely far in the future, research and understanding is making more and more progress every day. To find a cure for schizophrenia, scientists must first understand the disease itself. Over the year

It was known at the time that DNA was present in the nucleus of every living cell, and that it had something to do with heridity, but without a knowledge of its structure little more could be understood about how it actually worked. They approached the problem with the same methodology that had been pioneered by Linus Pauling, who after years of exhaustive study ha

The English scientist Robert Hooke who used a makeshift microscope of his own invention to examine a variety of objects, including a thin piece of cork, made the first observations of cells in 1665.

While Hooke was the first to study and describe cells, he did not realize their

What is Cancer What is cancer? Cancer is the abnormal and uncontrolled growth of cells that if left untreated can ultimately cause death. The word cancer came from the Greek word for crab, karkinos. The early Greek physicians who first described cancerous tumors had no notion of their cause or true nature, but they were struck by the resemblance if some invasive tumors to crabs: a hard mass with a claw like extensions and an aggressive nature. Cancer causes about 550,000 deaths a year. Although
