The oldest blood in the world is discovered from "Iceman"

ByScott Wilcoxson

It is said that it is a stone age human about 5300 years ago "Iceman"Since its discovery, research has been continued for a long time, but in the research using the latest technology succeeded in collecting blood for the first time from dry mummies. In addition, it turned out that Iceman was killed instantly after being killed.

IcemanIs a mummy who is supposed to have lived in the stone age about 5300 years ago, which was discovered in glaciers of the Alps Range near the border between Austria and Italy in 1991. It is also called "Ötzi (Etsui)" taking the name of the discovery place Etsu Valley, and the anatomical investigation has been continued for more than 20 years since it was discovered.

Currently in northern ItalySouth Tyrol Archeology MuseumIceman's mummies and restored cubes are kept in. It is speculated that the reconstruction solid is the following, with the upper body being naked, wearing fur on the feet, wearing fur shoes, and having hunting tools.


In the previous survey, although it turned out that Icemann achieved unemployed death due to a trauma or other trauma received on his back, finding traces of blood because it is made mummified It seems he could not do it. ItalianInstitute for Mummies and the IcemanAccording to Mr. Albert Zink, director of the Mummy-Iceman Institute (Mummy-Iceman Laboratory), there was no trace of blood even when Iceman's artery was opened, blood did not flow out of the body because blood bleeding due to arrow wounds was quite awful He was presuming that he was thinking.

In the latest research, we will surround the back and right hand scratches with the latest nano-sizedProbeSurvey using. Succeeded to record the movement of the probe with a laser, and create a detailed 3D image of red blood cells.

From the scanned images below, you can clearly see the rounded donut-shaped red blood cells with a recessed center.


Furthermore, by analyzing the laser wavelength pattern, we elucidated the molecular structure of the substance, and found out that this is red blood cell, it was discovered the world's oldest blood. Analysis of the blood adhered to the tools of the stone age in the past, it was possible to know the structure of the blood of prehistoric times, but pollen and bacteria similar to red blood cells are attached, so blood I was told that it was not certain.


Also,Atomic force microscopeAs a result of the survey using Icemann scarsFibrin (fibrin)Also found. Fibrin is formed in a few minutes when the body can be scratched and gradually disappears in case of a living human being, but the fact that fibrin was detected from Iceman's body means that he was injured It shows that it died soon from. "Since some of the researchers have been hurt by IcemanI survived for several hours to several daysSome people argue that, but it is a complete mistake, "Zink asserts.

The nanotechnology technology used in these surveys may be applicable to the investigation of contemporary murder cases. contemporaryLaw scienceIt is difficult to measure dry blood, but if you apply the technique used in this survey, it has occurred in skin and mucosaBlood spotMr. Zink positively talks about utilization of technology, because we can date dating, we will be able to analyze the blood of various conditions, Mr. Zink.
