Indiana University-Purdue University Indianapolis School of Science. "Forensics: New tool predicts eye, hair and skin color from a DNA sample of an unidentified individual: New tool will be used when standard forensic profiling is not helpful." ScienceDaily. ScienceDaily, 14 May 2018. <www.sciencedaily.com/releases/2018/05/180514083926.htm>.
Recently, a team of international scientists worked together to develop a breakthrough in DNA analysis. They were able to create a new DNA test, known as the HIrisPlex-S system. This test is revolutionary in the sense that it can be used to accurately and efficiently predict hair, eye, and skin color phenotypes from DNA. Previous methods were less effective since they struggled to determine skin color and ethnicity from a sample of DNA. This new system will be used to build forensic profiles of unknown subjects from crime scenes. It can also be used to validate or invalidate eye-witness testimony regarding the appearance of the unsub. Co-director of the study, Susan Walsh, explained how this new test uses genetics to “take an objective look” at what any witnesses believe to have seen.
This article is incredibly relevant. DNA analysis is being used more and more frequently in forensic laboratories. Therefore, there is an increased need for new, innovative test systems that are more accurate. The HIrisPlex-S DNA test system will make finding unsubs far easier since it makes precise determinations regarding their physical characteristics. Additionally, considering the heightened use of DNA databases by the authorities, it is fair to assume that this new test system will be used frequently.
I enjoyed reading this article. While at times, I thought that the authors could have gone into more detail, overall, they did a great job summarizing the relevant points from the study and new product. They were able to make reading about a rather dense subject quite interesting through their engaging style of writing.

For this week's current events, I decided to respond to Charlotte Cagliostro's analysis of "Forensics: New tool predicts eye, hair and skin color from a DNA sample of an unidentified individual: New tool will be used when standard forensic profiling is not helpful." Firstly, Charlotte does a great job describing and summarizing the main point of the article. "Recently, a team of international scientists worked together to develop a breakthrough in DNA analysis. They were able to create a new DNA test, known as the HIrisPlex-S system. This test is revolutionary in the sense that it can be used to accurately and efficiently predict hair, eye, and skin color phenotypes from DNA," writes Charlotte. She does a great job summarizing the topic of the article. She discusses the HIrisPlex-S system and explains its contribution to DNA prediction. Charlotte then does a great job explaining how previous methods of DNA prediction were much more inefficient than this one. "Previous methods were less effective since they struggled to determine skin color and ethnicity from a sample of DNA. This new system will be used to build forensic profiles of unknown subjects from crime scenes. It can also be used to validate or invalidate eye-witness testimony regarding the appearance of the unsub." Charlotte describes how previous methods did not work as well and were not that accurate, and also stresses how this method compared to the other ones will greatly contribute to the building of forensic profiles. Charlotte also does a great job stressing the relevance and importance of this method. "This article is incredibly relevant. DNA analysis is being used more and more frequently in forensic laboratories. Therefore, there is an increased need for new, innovative test systems that are more accurate. The HIrisPlex-S DNA test system will make finding unsubs far easier since it makes precise determinations regarding their physical characteristics." Charlotte explains in great detail how the new method of finding DNA will make it so much easier to identify unsubs as the HIrisPlex-S very accurately can find information surrounding the physical characteristics.
Although Charlotte did a good job at analyzing the article, she could have used more direct quotes from the author to make the author's perspective clearer, so that the reader can understand the author's point of view better. Additionally, explaining the way the HIrisPlex-S works in more detail would give the readers a better understanding of the scientific breakthrough that occurred.
Overall, Charlotte did a good job summarizing the article, as she highlighted and reflected on the main points. She summarized the contributions of the HIrisPlex-S to forenics, and overall did a good job discussing how it will help identify unsubs.

For current event #5, I had the pleasure of reading Charlotte Cagliostro’s report on the article "Forensics: New tool predicts eye, hair and skin color from a DNA sample of an unidentified individual: New tool will be used when standard forensic profiling is not helpful." The first thing I thought she did well was provide easy to comprehend information right off the bat in the first paragraph;It was concise yet informative. The second thing I thought she did well was write in a sophisticated style. It added a professional tone and made for a well constructed write up. The last thing I thought Charlotte did well was include how previous methods were less effective than the new updated ones. I like that she took information from the past to back up more current/relevant points about the progression of the method.
As much as I enjoyed reading Charlotte's report, there were two things she could have added/fixed. One, she could have included more of her opinion in the second paragraph. I love how much evidence she used from the article, but I wish I had seen how she herself felt about the claims made about the methods she spoke of. Second, I would have liked to see some more quotations from the article. I feel that some points she made could have been nicely backed up by a quotation in the article.
Overall, Charlotte did a great job researching a very compelling article. Not only was her writing extremely informative, but was easy to understand, Although she was missing some details, I think she executed this assignment quiote well. I hope to read more current event reports like this in the future.

For this week's current events, I have decided to analyze Charlotte's response to "Forensics: New tool predicts eye, hair and skin color from a DNA sample of an unidentified individual: New tool will be used when standard forensic profiling is not helpful." First off, Charlotte provided information that was easy to understand with short, easy to read sentences. Next, Charlotte included how the old methods of DNA sampling were less effective compared to the new ones, which shows the relevance of her topic. Lastly, I enjoyed how, despite the authors not going too in-depth about the new DNA sampling, Charlotte still provided a simple and easy to understand summary.
However, two parts could have been improved. One, she could have elaborated on her own opinions rather than continuing to expand on the DNA sampling. Also, I wish she explained precisely how the DNA sampling is different rather than just saying it is better. I feel like elaborating on how it is different, as well as possibly adding a few quotations, would have added more credibility.
Overall, I enjoyed reading Charlotte's piece. Although she could have added more detail, it was still concise and informative. It was interesting to learn about the future of DNA analysis. I hope to read more current events like this in the future.

Charlotte’s review of “Forensics: New Tool Predicts Eye, Hair and Skin Color from a DNA Sample of an Unidentified Individual: New Tool Will Be Used When Standard Forensic Profiling Is Not Helpful” published by Indiana University-Purdue University Indianapolis School of Science in ScienceDaily was very well written and extremely informative. She did a good job of first introducing this new test, and sharing why it is so revolutionary, and how it actually works. In addition, Charlotte did a good job of explaining the various ways this test could be used. For example, to validate or invalidate eye-witness testimony or build forensic profiles of unknown individuals. Lastly, Charlotte also did a good job of pointing out what the contributors to this piece could have done better. The article really is just a summary and does not go into much depth and I think Charlotte is right in pointing out that flaw.
While Charlotte did a good job of summarizing the article and the contents discussed there were a few things she could have done to make her review better. First, I think the review could benefit from more analysis on her part. She did a good job discussing what the article is about and how the new technology will be used but does not really expand beyond that and offer her own opinions. In addition, I think if Charlotte maybe could have mentioned a case this new test might be beneficial in that it would have made the whole concept much more realistic as the reader could see a real example of when this was used.
Overall, I found this article and review to be very engaging and informative. The article talks about how this new DNA test can be used to create forensic profiles of unknown subjects and this could be really important during an investigation when looking for suspects. If investigators find DNA but don’t have any way of connecting the DNA to a person or a type of person the DNA may be useless. This helped give me a better understanding of how important DNA profiles are in finding suspects and potentially validating witness testimony. Previously, I had not realized how complex this was, and I didn’t know there was often concern that eye-witnesses may be lying about what they saw.

For Current event 6, I read Charlotte’s review of, “Forensics: New tool predicts eye, hair and skin color from a DNA sample of an unidentified individual: New tool will be used when standard forensic profiling is not helpful”. Of the many things done well in this review, the most noticeable to me was her insightful critiques of the article. It is evident that Charlotte spent time reflecting on the article (both its pros and cons). Secondly, she did a good job writing an informative summary that included all necessary pieces of information from the article. I liked that Charlotte specifically stated that this new, revolutionary method is more effective than methods of the past because it spoke to the importance of this new method in the modern world.
One thing Charlotte could have done to improve this review would be to expand more on her insights and opinions rather than summarizing the facts presented/opinions of the author. Secondly, I believe she should have added more quotations to bring some credibility to the facts she was presenting.
Overall, Charlotte did a great job with this review. I found her writing to be engaging and interesting, but I would have liked to hear more about her personal opinion. I enjoyed both the review and the article. It is interesting to read about how even at a time when we are so advanced in technology new methods are always being pioneered in scientific fields.

For this week's current event I read Charlotte’s review of the article, “Forensics: New tool predicts eye, hair and skin color from a DNA sample of an unidentified individual: New tool will be used when standard forensic profiling is not helpful.” After reading Charlotte’s review on this article I think she did a great job writing about this article because she explained the main points of the piece and made it easy for the reader to comprehend. She also did a great job contrasting the new and old methods of DNA sampling which helped emphasis why the new version was so important. Lastly, Charlotte did a great job of giving the author of the article a good critique because it is important to recognize the flaws.
I really enjoyed reading Charlotte’s piece but if she added a few more things I think would have really made her review stand out. One thing I wish was added in this review was direct quotes from the article which would increase the credibility of this review. I also wish that Charlotte discussed her opinion on the piece more.
Overall, I really enjoyed reading the review that Charlotte wrote, it was very well written and interesting to read, it gave me a great insight to this article and I am curious to learn more now.
During the current week's recent developments, I chose to react to Charlotte Cagliostro's investigation of "Legal sciences: New apparatus predicts eye, hair and skin shading from a DNA test of a unidentified individual: New device will be utilized when standard legal profiling isn't useful." Firstly, Charlotte works admirably portraying and abridging the primary concern of the article. "As of late, a group of global researchers cooperated to build up a leap forward in DNA investigation. They had the option to make another DNA test, known as the HIrisPlex-S framework. This test is progressive as in it tends to be utilized to precisely and productively anticipate hair, eye, and skin shading phenotypes from DNA," composes Charlotte. She works admirably abridging the theme of the article. She talks about the HIrisPlex-S framework and discloses its commitment to DNA forecast. Charlotte at that point works admirably clarifying how past techniques for DNA expectation were significantly more wasteful than this one. "Past techniques were less compelling since they attempted to decide skin shading and ethnicity from an example of DNA. This new framework will be utilized to construct criminological profiles of obscure subjects from wrongdoing scenes. It can likewise be utilized to approve or refute onlooker declaration in regards to the presence of the unsub." Charlotte portrays how past techniques didn't fill in too and were not unreasonably precise, and furthermore focuses on how this strategy contrasted with different ones will enormously add to the structure of criminological profiles. Charlotte likewise works admirably focusing on the pertinence and significance of this technique. "This article is unimaginably significant. DNA investigation is being utilized increasingly more as often as possible in measurable research facilities. Hence, there is an expanded requirement for new, inventive test frameworks that are progressively exact. The HIrisPlex-S DNA test framework will make discovering unsubs far simpler since it makes exact conclusions with respect to their physical attributes." Charlotte clarifies in extraordinary detail how the new strategy for discovering DNA will make it such a great amount of simpler to recognize unsubs as the HIrisPlex-S precisely can discover data encompassing the physical qualities.
Despite the fact that Charlotte worked superbly at breaking down the article, she could have utilized more straightforward statements from the writer to make the writer's viewpoint more clear, with the goal that the peruser can comprehend the writer's perspective better. Moreover, clarifying the way the HIrisPlex-S works in more detail would give the perusers a superior comprehension of the logical leap forward that happened.
In general, Charlotte worked admirably condensing the article, as she featured and thought about the primary concerns. She condensed the commitments of the HIrisPlex-S to forenics, and by and large worked superbly talking about how it will help recognize unsubs.
