Recently scientists have been able to determine the age of a person from there blood. This is possible because the method in which this is preformed takes advantage of T-cells, which are fundamental in the immune system. When DNA cells and T-Cells come together they form circular DNA cells and which are known as TCR cells. These TCR cells decline at a constant rate with age. This method was crated by Manfred Kayser of the Erasmus MC University Medical Center.
This will help forensic science because it gives investigators another means of identification besides bone and teeth marks. Also if a criminal or missing person was bleeding at the crime scene it would be easier to find their age with the blood instead of other techniques. Another reason why this method helps benefit Forensic science is that if a criminal is not in the DNA database then there is not information on them. However using this technique one can find out the age of the criminal or missing person.
I found this article to be very interesting because it shows us another one of the many Forensics techniques. One thing that would have been better about this article would be if they gave an example of when this method was used, and proven helpful. But over all I think that this was a good article.

This current event summary is well put together; it is to the point, a good length, and good at explaining the new method in determining age from blood in a neat, organized manner.
One thing I would like to know more about is the other techniques that are used to determine the age of a blood sample (besides from teeth and bones). I would also like to know more about how TCR cells work.
Something new that I learned is that that this new method of determining age from blood can contribute info about a criminal that is not in the DNA database
