Modern technologies, social media, and media freedom Essay

Modern technologies, social media, and media freedom - Essay Example It is certain that the next platform shall offer better communication links between two or more peoples. In addition to that, communication may be faster as compared to the current communication speeds. The Internet as a modern technology has led to the rise of the social media (social networking) networks such as FaceBook, Tagged, Hi5, Twitter, MySpace etc. The social media in turn has its positive and negative influences on media freedoms/freedom of expression globally. Based on that notion, this paper shall seek to analyse how social media has affected media freedom. In addition, the paper shall also look into the way forward with regard to social media and its impacts. The social media has its positive and negative effects which we all have to live and deal with as a society/ globally. One of the positive effects of social media is that the information exchanged is in real time (immediately). However, this is the same aspect that has a negative impact with regard to social media existence. A good example of social media gone badly and affecting media freedom is when there were riots in London and Twitter was apparently the modern technology that was being used to â€Å"propagate† the riots. Apparently, Twitter was alleged to have â€Å"mobilized† the riots which initially started in Tottenham and due to the posting of pictures in Twitter, the riots spread very quickly to neighbouring cities such as Walthamstow, Enfield, Waltham Forest and Brixton (â€Å"The Huffington Post,† 2011). Self expression: Different people have different ways in which they express themselves. Some people may express themselves in a manner that deems fit to them alone but not to everybody. Hence, a lot of people think that they can express themselves as much as they want without being held accountable for what they say or do. According to a survey that was conducted on the awareness of the legal consequences surrounding social media postings, approximately 65%

Stem Cell - Research Paper Example Thus stem cells are the basic root for the existence of the multicellular organisms. These stem cells previously were not given enough heed to be researched upon, but recently as the world of medicine has improved research on the stem cells have become an important breakthrough in the world of science (Solo & Pressberg 2007). Stem cells can be of two types which are embryonic stem cells and adult stem cells. Embryonic stem cells are retrieved from human embryos whereas adult stem cells are retrieved from the organs of adults. Because of the stem cells to proliferate rapidly and form organs it is important for the medical experts to discover the inner functioning of these stem cells. And thus it has become important to retrieve these stem cells from the embryo and adults. The ethical issue arises in the concept of retrieving the stem cells from human embryos. In the process of retrieving the stem cells the scientists have to destroy the human embryo and in this process a death of a hu man being may be caused as believed by the opponents of stem cell research. However the proponents believe that the embryo has yet not developed enough to be called a human being and thus a life is not being taken. This essay would further revolve around both these view points and would provide with a definite conclusion as to which view point is more convincing (Newton 2007). According to the scientists stem cell research can be a breakthrough in the medical world to cure many of the diseases which are causing deaths. These stem cells give birth to the organs in the body and it is because of these stem cells that a systemic way of functioning is observed in the human beings. Thus the very reason of the existence of these organs can help to transform many medical researches into success. The exact functioning of these stem cells can help the doctors to replace organs which have become dead or diseased due to any condition in the human being and they can further provide ways to compl ete healing in a human being. It is believed that successful research on the stem cells can provide a way for breakthrough in the cure of genetic and nervous disorders. Stem cells can help to replace the neurons placed in the body if the research is successful and the parts of brain which are not functioning may be able to function because of these stem cells (Newton 2007; Solo & Pressberg 2007). The question now arises as to why these stem cells are not being used for research by the medical experts. The answer is given by the controversial debates of the moral thinkers. Human Embryonic Stem Cells can be retrieved from the inner cell mass of a blastocyst. As a human embryo begins to develop a blastocyst is formed which consists of an inner cell mass and an outer cell mass which is known as trophoblast. Acquiring the stem cells requires the destruction of the outer cell mass of trophoblast and thus the immediate death of the embryo (Thomas et al 1998). This death of the embryo has c aused many arguments to be raised against the stem cell research. According to the opponents the killing of embryo is just like killing an innocent citizen and depriving him of his rights. These opponents argue that a life emerges the very moment a zygote is formed because of fertilization and after this process the killing of the child would be unethical and against the rules of this world. (George & Gomez-Lobo 2002, 258). However the proponents for stem cell research
