Oldest Intact Red Blood Cells Found on Iceman

The scientists used atomic force microscopy, a visualization method with resolution of less than a nanometer, to scan the wounds for blood residue. They discovered red blood cells — the oldest in the world to be found intact — as well as fibrin, a protein needed for blood to clot. The presence of fibrin indicates that the Iceman, nicknamed Ötzi, didn't die immediately after being wounded."
