Criminals Who Eat Processed Foods More Likely To Be Discovered, Through Fingerprint Sweat Corroding Metal
A researcher at the University of Leicester and scientific support officer at Northamptonshire Police, by the name of Dr. John Bond, stated that people who enjoy processed foods are most likely going to be incapable of hiding evidence they leave behind at a crime scene due to the fact that fingerprint marks will be more visible because they have high salt levels in their body. He said that a person with a high salt content is more likely to sweat and as a result would leave a stronger and more visible fingerprint on metal. He was able to create a method that allowed scientists to see fingerprint marks even after they were removed. He and his colleagues brought about a study to show that fingerprints can abrade on metal surfaces. People with high salt levels will sweat more because the body must get rid of excess salt. When salt leaves our body it comes out as sweat through the pores in our fingers. The more salt, the better abrasion on a piece of metal. Therefore, the chances of finding someone in a crime are higher in a person who has high salt concentration.

I think the author did a good job presenting the information in a way that was easy to understand. She thouroughly explained what the new study expressed, and her resume was not too long.
To improve, she could have included a bit more specific data and she could of elaborated on how this would help forensic scientists.
I learned that eating salty foods leaves a better fingerprint!
This article was very enjoyable to read. The way in which you presented made the article easy to understand as well. I liked how you throughly gave some background on the new study and included specific data as to how this salt technique is useful to forensic scientists. My only suggestion would be to tell us how this technique is fairing now in the world of forensics. It's very interesting that you can make a better fingerprint by eating salty foods!
Very good job explaining the article. The information was presented well and the detail given about how salt affects fingerprints was helpful. The only thing that the author could change would be to give specific examples. I did not know that salt would impact a fingerprint left behind.
I think she did a good job summing up this article, it was clear and concise and got to the facts quickly. It could have been a bit more specific, with maybe some more details about how they discovered that salty foods contributed to the more present finger prints though. I learned that eating salty foods could leas to a more present fingerprint which is a very interesting breakthrough.
I agree with alex and schuyler and feel that lauren did do a good job summerizing the article. I found it very interesting that just by something as simple as what the criminal eats could improve the chances of identification. I think it's fascinating how technology is advancing and how new breakthroughs provide new details making it easier to solve a crime.
I thought this was a good article, especially about the method to see fingerprints marks even after they were removed. I found the salt levels in the body making the fingerprints more visable to be very interesting. I wish she had gone into a little more detail about how he was able to this method, and what it consists of. In the end this is a very interesting article and nice to learn not to eat a lot of salt before i commit any crimes.
The article was very interesting because I never knew that criminals who happen to eat processed foods are more likely to be identified through fingerprint sweat. To make the summary better, I would have included how forensic scientists are using this now and how it is making their job easier. But overall, it was well written.
