Unformatted sample text from the term paper:
or air for new species, scientists have overlooked a great deal of life that exists on the planet (Cooke, 1997). Indeed, it seems that even children have been looking
through microscopes for some time, but what is really new in the field? Actually, there are now new tools that scientists can use to study the microscopic world that
seems much more complex than what was known as late as the 1980s (1997). Cooke (1997) claims that new finds of late are equivalent in magnitude to Leeuwenhoeks
first look at microbes (1997). What is Cooke talking about? It seems that during the past ten years or so, new techniques have arrived that allow scientists to study cells
and because of this, new doors have opened. This is particularly evident in respect to forensics as watching trials seems to be a hodge podge of talk about PCR testing
and DNA evidence. Indeed, new techniques have revolutionized the field. Before delving into such things, it pays to look at the tried and true methods of studying cellular constructs.
Scientists have been looking at cells for centuries but today, there are many techniques available to explore cellular structures. The techniques and methods of studying cell and cell structures, for
microbiologists, are generally reliant on microscopes. Obviously, the cell cannot be seen with the human eye alone, and so, one needs applicable tools to view the cells and the structures
of them. Of course, examining cells today really goes far beyond the typical scope that many laymen are used to. In studying cells, there are various types of microscopes such
as light white, phase contrast, and ultraviolet ("Techniques," 2003). There are also electron-scanning and transmissions microscopes (2003). Other ways of studying cells include cell fractionation and immunocytochemistry (2003). Techniques
