...One man who was anything but skeptical of Avery’s research was James Watson, a young American student and former child prodigy. Watson was born in 1928 in Chicago, Illinois, and he attended the University of Chicago for college, where he earned a bachelor's degree in 1947. In 1950, he received a PhD in ornithology from the University of Indiana, and, after reading What is Life? By Erwin Schrodinger, decided to pursue genetic research. The problem was, Watson had almost no experience whatsoever in chemistry. In 1950, Watson began his studies with a microbiologist, where he was assigned to write a thesis paper on phages, a simple type of virus. These studies proved difficult due to Watson’s lack of chemical knowledge, and his supervisor realized that more information about phages, proteins, and genes would become apparent if they understood the structure. In attempt to acquire some basic chemical experience, Watson began a short internship at a lab where he nearly caused a catastrophic explosion. Following this unfortunate incident, Watson’s knowledge of chemistry remained unimpressive, as shortly thereafter, the...

...great scientist that many students of science learn of, born in 1877 Walter began by studying grasshopper chromosomes and in 1902 Sutton made a discovery and deduced that chromosomes were the base of heredity. His paper drew the connection between Mendel’s laws of heredity and chromosomes. While conducting his research Walter would have been limited by technology and ideas of the time for example during this time period religion was very powerful and manipulated and shamed many discoveries during this time period that disagreed with their beliefs in this case it meant that a person was not created by god but by DNA. Another limitation that Walter had while researching was the technology available at the time the high tech microscopes needed to assist his research were unavailable. Another great scientist is Thomas Hunt Morgan. American geneticist Thomas Hunt Morgan, (1866-1916) is credited with confirming the relationship between chromosomes and heredity in 1910. As well as the discovery of a pair of chromosomes called the sex chromosomes that determine the sex of offspring, Morgan’s fruit fly breeding experiment showed that the information carried is in the form of genes. He was the first geneticist to associate a specific gene with a specific chromosome. Morgan’s research team carried out experiments with white-eyed male fruit flies and red-eyed females flies. After a multitude of mating’s Morgan’s team concluded that white eyes were a characteristic that the male chromosome possessed...

...Microbiology Mid Term Review What contribution did these dudes make to science and what type of experiments were involved in the discoveries they made? Louis Pasteur- Heat pasteurization- 1st vaccine for rabies. Found alcohol only produced in wine if yeast was present. “Swan necked” flasks experiment for spontaneous generation. Robert Koch- Studied anthrax, Koch’s postulates (germ theory) studied and awarded for TB research. Anton van Leewenhoek- Made the 1st lens to observe living microorganisms. The lens magnified up to 300x and were free of distortion. Edward Jenner- Studied small pox. Came up with the first vaccine for smallpox. Alexander Fleming- Discovered lysozyme (an enzyme) was found in tears, saliva, and sweat could kill bacteria. What issues and types of instruments are involved in visualizing bacteria and viruses with a compound light microscope? Reflection- transmission-absorption with florescence-refraction. Condenser-is a lens that serves to concentrate light from the illumination source that is in turn focused through the object and magnified by the objective lens. iris diaphragm-regulates the amount of light on the specimen. objective lenses- magnifies ranges from 10x to 40x, ocular lenses. stage- supports the slide for viewing. focusing knobs-moves the stage up and down for focusing. total magnification- take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. What are the differences...

...Program in Writing and Rhetoric Autumn 2005 Honorable Mention Matthew Gribble Instructor’s Foreword Movies tell us that in the wake of a murder, detectives would stretch what appear to be pipe cleaners, or a very taut yarn, through the bullet holes left in walls, in lamps, in the hollow doors of haunted rooms. The yarn was there to demonstrate the location of the shooter – or indeed, shooters – relative to the victim. But the fact is that other forces might have conspired in the murder. (Poison may have been used; bullets may have been fired only as an afterthought; perhaps they were fired by the victim himself, before he died . . .) Yarn can tell us the story only in certain circumstances. As a researcher and a writer, Matthew Gribble analyzes his crime scene with diligence and care. The crisis: The shortage of nurses in America. The question: How and why did this shortage become a persistent problem? Matthew affixes strings of yarn to a number of gunshots: the increasing average age of the workforce, long hours, work that is often menial or clerical, and finally, relatively low salaries. But these strands lead to new questions, wider causes which have nothing to do with social yarn. These new questions have to do with rhetoric and the enduring association of nursing with “women’s work” and “femininity.” Matthew has the audacity to ask how the rhetoric of femininity actually functions. How and why are we compelled to accept images and tropes as ‘normal’ or ‘natural’ when...

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...
