Carbon dating forensic science

According to Explore Forensics, one of my favorite sites, crystallins got their name because of how they react under a microscope–like crystals, allowing light to pass through. Let that sink in) until age two, these crystallins form in and around the lens of the eyes. When this happens trace elements of carbon permanently fuse in between the crystallins.

So when an investigator–usually a scientist or pathologist–conducts a Radiocarbon Dating examination s/he’s looking at the levels of the carbon fused with the crystallins.

Even though it contracts afterward, it never fully returns to its original size.

In the picture above notice the heart-shaped space.

Radioactive particles and naturally occurring carbon settle in the crystallins of the eyes, and Radiocarbon Dating is the process of detecting this manifestation.Crystallins are microscopic proteins that bind together and collect on the lens of the eye.The acetabulum—the socket where the femur (thigh bone) meets the pelvis—is larger in males.Also, the head and skull have several characteristics indicative of one sex or the other.
