...Rosalind Franklin Research Paper Rosalind Elsie Franklin was born in July 25th, 1920 on Notting Hill, London, England. She came from a family that was very involved in social and public works. Franklin's father wanted to be a scientist, but World War I cut his education short, and therefore, he became a college teacher instead. From an early age Rosalind Franklin was extremely intelligent. By the age of 15 she knew what career path she wanted to follow, being a scientist. However, her father strongly discouraged her interest since it was very difficult for women to have a career in dominantly male field. Though, with her excellent education from St. Paul's Girls' School, one of the few institutions at the time that taught physics and chemistry...

...The discovery of the structure of DNA James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin What did they discover about DNA? James Watson, along with Francis Crick, studied the molecular structure of DNA that had been extracted from cells and showed how it could serve as the chemical basis of inheritance. Although it is commonly known that everything they "discovered" they stole from Rosalind Franklin, who proceeded to obligingly die. That said they're incorrectly famous for discovering that DNA is composed of sequences of purines and pyramidines hydrogen-bonded together and held in place by two sugar-phosphate strands that form a double helix due to more hydrogen bonding. Maurice Wilkins is not credited for the actual discovery of the structure of DNA rather that distinction goes to James Watson and Francis Crick and is known as the Watson-Crick model. Wilkins did share in the Nobel prize because his work in spectroscopic studies on nucleic acids led to the use of X-ray crystallography to define the Watson-Crick model of DNA. Rosalind Franklin discovered the molecular structures of DNA, RNA, viruses, coal and graphite. She was a British biophysicist and X-ray crystallographer who was best known for her work on the X-ray diffraction images of DNA which led to discovery of DNA double helix. Rosalind Franklin's critical contributions to the Crick and Watson model include an X-ray photograph of B-DNA (called photograph 51), that was briefly shown to James Watson...

...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...

To start, with much effort, including analyzing a three mile long paper, Bell Burnell discovered information about pulsars, remnants of supernovas. However, she was not included in the acknowledgment of the discoveries, her male supervisor was awarded instead. "The picture people had at the time of the way that science was done was that there was a senior man—and it was always a man—who had under him a...

...James Watson is an American scientist. He is famous for many different discoveries and theories that are still in use today. He is a very intelligent person who along with his colleagues, worked hard to achieve his goals no matter what. Without him, there would be less advanced research in the world of science today. James Watson was born on April 6, 1928. This means he is currently eight-seven years old. He was born in Chicago, Illinois (whatisbiotechnology.org/ dnalc.org). James is the oldest child in his family. He is the son of James Watson and Jean Mitchell. His father was a businessman, while his mother was a tailor (nobelprize.org).

...Pharmacology Phunland When people go to an amusement park, what do they look forward to the most? Cool rides? Great food? How about learning in a themed atmosphere? At Pharmacology Phunland, you’ll get all three! Your family will have a blast in our park while learning all about medicine advances in the 20th century. There are three sections, all with their own specified theme and rides. Additionally, there are two cool restaurants in which your family can enjoy exotic foods. Learn all about the deadly virus in Polio Park! Featuring fun for the whole family, along with a valuable learning experience, Polio Park is themed around the highly infectious virus that swept the world. Being depicted as early as pre-history, polio is a virus that can affect the central nervous system and lead to the destruction of the motor neurons. This can lead to muscle weakness and paralysis. Before the 20th century, polio was found mostly in children between 6 months and 4 years old. However, before the mid-19th century, people who lived in poorer sanitation areas were constantly exposed to the virus, thus creating immunity. By the early 20th century, huge improvements were made in community sanitation. This lead to a pandemic outbreak of polio in Europe, North America, Australia, and New Zealand during the first half of the 19th century. By the mid-1950s, there were not one but two different versions of the polio vaccine. This cut polio outbreaks drastically. In this park, all of the rides have...

...Facebook Unethical Use of User Data for Social Experimentation Bonita V. Earls Longwood University Abstract His paper explores the ethical impact of Facebooks 2012 study on emotional contagion in a social web environment. The study is controversial due to the fact Facebook researchers failed to follow standard ethical guidelines as set forth in the healthcare industry, failed to clearly communicate the study, its intentions, and methodology to its users, and manipulated data in such a way it invoked emotional and mood changes of its unaware users. The idea of algorithmic program use in the social media sphere comes into question as well. Introduction In January 2012, the news feeds of approximately 700,000 users of the popular social media site, Facebook, were manipulated in a manner so that some of its users only had positive news stories show up on their pages and others had only negative news stories show up. The experiment was conducted over the span of a week, from the 11th to the 18th, without the knowledge of the users (Kramer, 2014). According to the researchers, the goal was to see if “emotional contagion” occurs without direct interaction between people and in the absence of nonverbal cues. By manipulating the news stories, either all positive or all negative, they could study what effects, if any, there was on the moods of the users (LaChance, 2014). This is only one of many social experiments that the Facebook Core Data Science Team, has performed...

...ver the past 10 years of teaching courses on research methods and feminist approaches to methodologies and epistemologies, a recurring question from our students concerns the distinctiveness of feminist approaches to methods, methodologies, and epistemologies. This key question is posed in different ways: Is there a specifically feminist method? Are there feminist methodologies and epistemologies, or simply feminist approaches to these? Given diversity and debates in feminist theory, how can there be a consensus on what constitutes “feminist” methodologies and epistemologies? Answers to these questions are far from straightforward given the continually evolving nature of feminist reflections on the methodological and epistemological dimensions and dilemmas of research. This chapter on feminist methodologies and epistemologies attempts to address these questions by tracing historical developments in this area, by considering what may be unique about feminist epistemologies and feminist methodologies, by reviewing some of sociology’s key contributions to this area of scholarship and by highlighting some key emergent trends. The chapter begins with a brief overview of the theoretical and historical development of feminist epistemologies, followed by a similar overview of feminist methodologies. The final section discusses how feminist 36 epistemologies and feminist methodologies have begun to merge into an area called feminist research and details some key pillars of contemporary...

...you took the DNA from a human and rearranged the letters in the right way, you could produce an oak tree—arrange them slightly differently and you would have a bumble bee—arrange them again and you would have the instructions for making a bacterium. Acting through more than two billion years, the process of evolution has taken one basic idea—a molecular code that uses four letters—and used it over and over, in millions of combinations to produce a dazzling array of life forms. As far as we know, we are the only creatures on the planet that have figured this out. The members of our species who get the credit for this discovery are James Watson and Francis Crick, although many others helped including Maurice Wilkins and Rosalind Franklin. Some believe Franklin was denied the Nobel Prize because of her gender but careful review of the facts will show that...
