The television show CSI : Crime Scene Investigation seems to solve any case that is thrown their way. They solve it by using any means possible even if the way they solve it is not a real-life technique. With technology evolving and helping science evolve, new possibilities are around the corner. In this article, it is revealed that a new tool is coming into play that will be able to determine whether a fingerprint was recently left or was left there long ago. Police investigators who rely on fingerprints left by perpetrators to help solve their case can now take an ease with this new technology coming out. Fingerprints can led to clues to the owner's’ age and gender with the help of the patterns (loops, arches, whorls) integrated in the fingerprints. Shin Muramoto and his colleagues have recently been studying the molecules in fingerprints and found that a substance call Palmitic Acid migrates away print ridges at a predictable rate. With the help of this acid, scientists can tell how long a fingerprint has been there. although their findings only apply up to four days, they hope to expand the window to ten days.
This affects our society today in many ways. This will first help people who have been wrongly accused of being in the place at the time of death. This will help them because they can test if the fingerprint has been there for X amount of days and compare it to the person's where abouts. This will in general help law enforcement rule out suspects and gain new ones. This will be a huge help in putting criminals behind bars and not allowing any of them to slip through the cracks.
It would have been helpful if the article gave an example where this technique has been used to solve a crime. The article did include however all the information needed to understand the process of this along with the importance of fingerprints.

I thought Martin did a great job with his review of the article. One of the great things about his review is the way he opens it. Starting the review with a hook about a show that many people watch and love makes the review much more intriguing and made me want to read it more. Another thing Martin did well in his review was stating how this important issue of new technology impacts our society today. This part of the review is arguably the most important, and the fact that Martin made it clear how and why this new forensic technology impacts society is very impressive. Finally, I thought that Martin did a great job when it came to discussing the future of this new forensic technology. While it was only briefly mentioned, it was crucial that he mentioned how scientists are hoping to expand that window of days a fingerprint has been at the crime scene from four to ten days. This brief mention shows the importance of this new technology, as it is clearly very important to forensic scientists.
While Martin did many things very well, I thought that one of the things he could have improved on in his review was going in depth on who Shin Muramato and his colleagues are. I felt as though his name was mentioned abruptly without much detail, and it would have been a little bit clearer had there been a brief background on him and his colleagues. One other thing that Martin could have improved on is the structure of his writing in part of the review. In the second paragraph he begins many consecutive sentences with “This will…”. I felt as though that made the review a little muddled and it would have been a bit clearer if he had changed the structure a little bit.
Overall I thought Martin did a great job with his current event article review. I was very impressed that scientists can now tell how many days have passed (to a certain extent) since the fingerprints had been at a crime scene. I honestly could not believe that that kind of technology is available nowadays. I also think it is great that such an important technology is added to forensic studies, as it can definitely help when it comes to solving a crime.

I though that Martin's review of this article was very well done. I though that the beginning of the review grabbed the reader's attention, since he gave a brief synopsis of the article. I though that the review was short and to the point, which means that it doesn't bore the reader, this is a review, not an article. He did a good job of summarizing the whole article in a little amount of words. I thought that he also conveyed the importance of the article, not only does he give the reader a good idea of what the article is about, he also tells them why the article is relevant. Although this was a good article, I thought that perhaps he could have gone a little bit more in depth about how the process works. I also thought that perhaps the review could have been a little bit longer. Overall, I thought that this was a good article and I was impressed by how far we have come in forensic science. I think that this technology will do a good job at helping to prevent criminals from walking free in the future,
I thought martin's review of the article on the new CSI fingerprint tool was very informative and thorough with explaining how and why this tool works in a short summary basically covering all the key points instead of just filling space with useless information, I was interested in what this kind of tool could be useful for and Martin failed to disappoint giving a simple explanation on how this tool works and how exactly it could be useful in crime scene investigations. It would have been helpful to see an example of how law enforcement officers have used this technique when trying to take down a criminal but Martin's review and the article itself had enough information to prove how a technique like this could be a powerful asset in the law enforcement system. I learned how this technique could rule out potential suspects and produce an even quicker means of identifying a criminal than the already outdated system.
I reviewed the article “A New CSI Tool Could Pinpoint When Fingerprints Were Left behind”. I like how Martin in his critique started off with an interesting sentence that made you want to read more. By starting off the article with a reference to a television show that many people watch, it helps people relate to the article and makes it a lot more interesting. I thought that he did a great job on the summary of the article and he did a good job on explaining the plot especially since the article wasn’t that long. Martin gave a clear explanation of how this new technology can help humanity, and talked about how this technology could improve.
Some things that I think the article itself could have worked on was incorporating quotes from Shin Muramoto and other researchers that helped invent this new technology. It would have been helpful to get the researchers thought on this new tech. I also think that although the article mainly focused on the ways that this technology could help with police investigations and how it could allow police to rule out suspects, but the article could talk more about the ways that this technology could go wrong (they only talk about the pros and no cons). The article could also go into more detail into the way that this tech actually worked and perhaps how it has helped in an actual case before.
Overall, I thought that this was a very interesting article to read although it could have included a lot more detail since the article was extremely short. This technology could definitely benefit police investigations and will help them eliminate several suspects. I was impressed at how fast technology can improve based on what the needs are. In this case, many things can be deduced from fingerprints that are left behind but the amount of days it has been there was a problem, and now a researcher has found a way to even figure out the amount of days a fingerprint has been there.
I liked this article right off the bat because it drew me in by mentioning the television show CSI. These shows have become very interesting to me since I have been taking Forensics. Another well presented aspect of his review is that it was simple to understand. I like the way he did not use difficult SAT words to get his point across. What I thought was particularly well presented was the fact that he listed all the ways that this new technology could be used to help forensic investigators.
The review could have been better if he had used that original article instead of the reprinted article. Since the article was only 241 words (“Story Source: The above post is reprinted from materials provided by American Chemical Society. Note: Materials may be edited for content and length.”), he could have sourced the original article from acs.org. This article included a video that provided slightly more information. Also, other people’s questions could have been answered with the video. Someone had a question about the identity of Shin Muramoto and his colleagues. The video touched upon this and it went a little bit more in depth about how the process works. Another improvement that could be made is the grammar. I did not quite understand the expression, ‘take an ease’ (relax, perhaps? but how? and why?); he needs capitals at the beginnings of each sentence (did you mean to make two sentences or was the period a mistake?); and then there was ‘process of this’ (did you mean the aforementioned process or did you forget a word after ‘this’?).
I was excited when I found out the information about palmitic acid. Apparently, we have palmitic acid on and in our skin. When we touch a surface, the palmitic acid is left behind in the only thing that touches it - our fingerprints. The spaces between our ridges and whorls do not touch the surface but over time, the palmitic acid leaks into the spaces. Since the rate at which palmitic acid flows is predictable, forensic investigators can determine how long the fingerprints have been there. Awesome. I wonder what the limit might be for dating fingerprints.

This current event was very well summarized and informative. This summary does a good job giving information about this new technique used to help crime investigators who rely on fingerprints left by perpetrators to solve their cases. It was interesting to find out that Palmitic Acid, a substance that is found in fingerprints, can help scientists determine how long a fingerprint has been there for. This technique is very useful and helpful in today’s world. Crime Investigators can now get extra information from a crime, using this tool. This will find suspects, and put them behind bars faster.
It would have been helpful to know when this acid was discovered, and how many cases have used this new tool so far. Also, it would have been great to have included an example of a case if it had used this technique.
It was interesting to learn how this acid can help scientist figure out how old a fingerprint is.
Martin did a great job summarizing and giving us all the important information without any extra information. One key thing I have noticed through all these current events, is that when they are too lengthy and full of facts and information I can't understand, I lose interest very quickly, and Martin did a great job grabbing my attention and keeping it due to the fact that it was straight to the point and interesting. It is very cool to see that we now have new technology and tools to see when the fingerprint was left at a crime scene, it can really help investigators at the crime scene and go a long way. The fact that the article chosen was quite short, to make it a little bit better, looking up further information could help benefit your reflection or current event. I thought this article was very interesting overall, and completely relevant. Just due to the length of the article, I think a little more background knowledge or research could have helped us, readers, better understand all the new technologies about finding out the fingerprints and when they were placed on the object's /crime scene. This information is helpful because it can help benefit police investigators when trying to figure out the suspect, and it could quickly eliminate many. Overall, nice job! Very easy current event to follow, and very interesting.
