In this article, scientist Dr. John Bond, of the University of Leicester and scientific support officer in Northamptonshire, England, claims that people who eat more processed foods are more likely to leave tell-tale signs at a crime scene. Dr. Bond claims that sweaty fingerprint marks make more of a corrosive impression (aka they are easier to see/print/identify) on metal if they have a high salt content, a characteristic common among those who just recently consumed fatty, processed, or fast foods. He developed a method of forensic research that enables scientists to "visualize" fingerprints even after the print itself has been removed, by studying, along with colleagues, the ways in which fingerprints can corrode metal surfaces. Although he is still investigating whether or not a sweat mark left at a crime scene to could analyzed to determine the suspect via a "sweat profile," he holds that a sweaty, or salty, fingerprint, makes it easier to identify, see, and use as evidence in a trial. Currently, he is working on the science of sweat at the University of Leicester to see if sweat can reveal more about the individual, such as health records, etc. The ability to analyze sweat would also allow for better investigation into terrorist attacks, where the attacks often destroy all available forensic evidence. Until then, sweaty fingerprints remain the best option for identification for Dr. Bond.

this article sounds intresting. i never knew that it is easier to find/pull up finger prints when the fingers are sweaty
I think that this review was very well presented. I liked how you showed us the different examples of how fingerprints are more easily found. Another things that I liked about this review was how you tied all the foods people ate and how that effected the fingerprints and made it easier to see. A final thing that I liked about the presentation of the article is that this man, Dr. Bond, is closely tied to the science of sweat and you make that clear because that is all the article talks about and how he studies it and how he thinks it effects forensics. Two things htat I think you could have presented better was probably to not be so repetitive about the fingerprints and how sweat effects them and that you only say a couple of scientists that work on the science of sweat. I think it would have helped a little bit more if you had explained that into a little more depth. One thing that I learned from this review was that if you have sweaty fingers you are more likely to leave a distinct fingerprint behind on the evidence.
This article was one of my favorite articles that i've read. I found it outstanding that finger prints are easier to pulle out when they are sweaty. This article was very well written and put into words.
I really enjoyed this article it was so interesting to hear that what you eat could effect things like your fingerprints. This was a great article to choose because I had no idea that this was discovered so it was fun to learn something new. It would have been nice to go into a bit more detail about the discovery but overall I found this review to be very well written.
In this article, the issue was described clearly, it had precise detail such as salt affecting fingerprints, and it was well presented why this is significant (against terrorist attacks).
To improve, the writer should not use aka and other abrivations that are not used in formal writing.
I learned what a sweat profile is.
I thought this article was very interesting. I did not know that certain types of food effected fingerprints. Also, I thought it was odd that there is such a thing dubbed as "the science of sweat", it seems like a very odd profession, yet useful in this case. Who knew that by studying sweat could stop terrorist attacks? I also find it interesting that you don't need the actual fingerprint, you can use the way that fingerprints corrode metal surfaces. I feel that this concentrated on the fingerprints so much, but didn't give detail on much else. Also, she could have expanded on the science behind the sweat, if that was included in the article. I did not know that food effected fingerprints.
I found Paige's current event very interesting because we can determine a lot of information from a sweat mark left at a crime scene. For instance, weather their body contains a large amount of salt from the food they eat, would indicate they eat fast food.
I learned from this article that sweaty fingerprints are the best form of identification of the person.
