New fingerprint breakthrough by forensic scientists
Researchers in the University Department of Chemistry and the Police's scientific support unit have developed the method that enables scientists to 'visualise fingerprints' even after the print itself has been removed. They conducted a study into the way fingerprints can corrode metal surfaces. The technique can enhance - after firing- a fingerprint that has been deposited on a small calibre metal cartridge case before it is fired.The University's Forensic Research Centre has been working with Northamptonshire Police's scientific support unit to develop new ways of taking fingerprints from a crime scene.The procedure works by applying an electric charge to a metal - say a gun or bullet - which has been coated in a fine conducting powder, similar to that used in photocopiers.

This article was interesting because it was clearly relevant, it covered a topic I was not yet aware of, and it was very unique. However, it could have been more descriptive, and was a little short. However, I overall found it educational.
This was an interesting summary, and I liked that the author chose an interesting topic. It was very relevant to the topic of fingerprinting and recovering evidence. To improve, the author could have added a bit more, and described the process with more detail. I did not realize that fingerprints could be recovered using a process involving an electric charge.
The articale was very intresting. Miranda did a good job. one thing that she could have done was add a little more information
I thought that this article was a very interesting topic, was easy to understand, and can be extremely useful in future criminal cases. The article was a tad short and could've explained the method the scientists use to uncover the fingerprints a little better. I think that this proves how new technology is very useful in solving crimes because of the innovative way this recovers fingerprints.
This article caught my eye immediately. I found the fact that scientist could now visualize fingerprints amazing. This article proves how technology has advanced and improved over the years. By this discovery, many more criminals are put to justice and this has opened a new window for investigators to bring justice to the victims. One thing I would improve about this article would be that I would make it clearer. This article was very brief and did not have a lot of information to help the reader better understand it. However, overall I found this article very thrilling.
This new way of identifying finger prints is amazing. The collaborative research by the University and the Police helped to prove the importance of such a find. The visuliazation of fingerprints and how they would be identified using similar techniques that a photocopier would use is very interesting. If more detail was put into this article I would give it a 10 out of 10, for now its a 9.
Great article. It was interesting to read about how fingerprints can be found using an electric charge especially since i have never heard of such a thing. It could have had a bit more detail describing the process and if it has been successful in any experiments but overall it was to the point and easily read.
This is a very interesting topic that shows amazing new technology. I would like to know more about this topic and how it works
This article is interesting because it ties into exactly what we're learning right now. The author should have went into more detail about how this process about how the electric charge tracks fingerprints. This will definitely be used often during crime investigations. Overall, the article was informative and well written.
