Ross Granville Harrison (1807 -- 1959)
Ross Granville Harrison was an American zoologist. He is known for his discovery of a method of growing cells outside of the body. In his famous experiment carried out in 1906 he placed a piece of a frog's embryonic nerve tissue into a drop of frog lymphatic fluid, and saw that the nerve tissue did not die, but rather continued to grow. (Ross Granville Harrison) The method that Harrison developed from this experiment was to form the foundation of the tissue culture technique used in modern medicine and in medical research. This technique has become an extremely important part of contemporary medical research as it allows for "…the study of isolated living cells in a controlled environment." (Ross Granville Harrison).
Harrison did not win a Nobel Prize for his discovery but many scientists and scholars felt that he should have received the highest accolade for his groundbreaking work. There is little doubt that the results of his research were extremely beneficial to medicine and the health of mankind. For example, one of his students devised a test for mumps using the technique devised by Harrison. His methodology was also used in the growth of polio virus cultures, leading to development of polio vaccine. (Ross Granville Harrison).
What is striking about the biography of this scientist is both his intellectual curiosity as well as his sense of ethics and morality. His intense intellectual curiosity can be in his continual research on scientific and biological problems. This is evident in that...
Digital Media and Its Effect on Human Activity The effect of digital media on human activity is evident in a number of ways: the Digital Age has dispensed with old media and inducted the way of new media (social media, digitalized media) into the lives of individuals living today (Weldon, Eadie, 2009).

WWI The assassination of Archduke Franz Ferdinand and his wife represented a culmination of several concurrent forces, all of which led to the outbreak of World War. The concurrent forces that led to World War One can be loosely grouped under the following categories: nationalism, imperialism, and militarism. Within each of these categories are ample sub-categories that can testify to the extent of forces that shaped the pre-war conditions throughout not
History Industrial Revolution What impact did the Industrial Revolution in England have on the American colonies? During the mid-eighteenth century, the Great Britain had started the Industrial Revolution; meanwhile the American colonies had not yet begun their journey towards industrialization. The main reason why the American colonies lagged behind the British was that the former had abundance of land and at the same time scarcity of labor. However, it should be note
Diversity -- with the exception of homophobia -- was beginning to be commonly accepted and praised. Technology -- such as the use of DNA in criminology and the introduction of the PC -- was becoming more prominent in the lives of everyday Americans. In the Cold War, President Gorbachev asked for openness and economic freedom, while President Reagan asked him to tear down the Berlin Wall, which he did.
Japan was particularly threatened by the construction of the Pearl Harbor base and the Panama Canal (World pp). On December 7, 1941, Japanese warplanes attacked Pearl Harbor, the largest U.S. naval base in the Pacific, and the following day, the United States declared war on Japan (World pp). Japan also attacked U.S. air bases in the Philippines, and immediately invaded the Philippines and the British Colonies of Hong Kong, Malaya,
National debt and veterans benefits for example drove a permanent increase in taxes, although these were not as high as during the war. The country's international economic position was also permanently affected. Its pre-war status as a debtor country was permanently changed to a net creditor, in the order of $6.4billion. Also, the power as financial world leader shifted from London and the Bank of England to New York,
