Vitreous Humor In The Eye Helps To Establish Time Of Death
Researchers from the University of Santiago de Compostela came up with a new method to estimate the approximate time of death. Its based on the vitreous humour of the eye of cadavers and, by using this system, scientists makes it possible ti establish the post mortem interval (PMI). This information makes it easier for the police and courts. Scientists analyze potassium, urea, and hypoxantine concentrations that are present in the vitreous humour of the ey and introuduce these things into a computer program. José Ignacio Munoz Barús, who was involved with the study, said that, "the equations we have developed now make it possible for us to estimate the PMI more precisely than before, and provide a useful and accessible tool to forensic pathologists that is easy to use." This new method is more flexible, useful and efficient than those applied in the past. The traditional techniques for estimating the PMI are based on the study of parameters such as the temperature of the organs.This new method offers an important contribution in the field of legal medicine, since determining the time of death has been an issue since the 19th century.

I think this was a well done summary. Geena did a good job of mixing the scientific side of the article while explaining it in a simple, understandable manner. It is interesting to hear of developments in forensics outside of the US so I'm glad that Geena chose an article that had to do with findings outside the US. I think that she also did a good job of applying this new discovery to the current forensics world and what the impact would be. I think she could have watched her spelling a bit more carefully and perhaps elaborated a bit more. Overall I thought this was very well done and I learned alot about new discoveries that victims can help forensic scientists with.
I found that this article was very interesting and very well summerized. I thought that Geena did an amazing job rephrasing the article in a matter that it is understandable. I love how she found an article that was outside the United States. This reminds us that scientific discoveries does happen outside the U.S. Overall very well done
