Immortality or resurrection has always been pursued by human beings, and there are always countless years of existence in ancient mythology. The efforts to pursue these two goals indirectly promote the development of human medical science and technology, so we see that the average life expectancy of modern human beings is getting longer and longer, and some areas have exceeded 82 years old, which is not far from the natural life limit of human beings. However, the idea of resurrection is still hopeless Ancient mummies have become shriveled and lifeless remains. What we can do now is to freeze the remains and minimize the damage caused by the freezing process of tissue fluid. So complicated treatment is needed.
America's richest man may have died. 1967, there is no technology to preserve the human body without damage. James Bedford's body was preserved in liquid nitrogen after being injected with dimethyl sulfoxide. DMSO has a certain toxic effect, interacting with hydrophobic groups of protein, leading to protein denaturation. So his brain may be damaged to some extent, and organ damage is better. The brain is the most important organ of the human body, and the destruction of brain tissue will make consciousness disappear completely. Because of its low temperature, liquid nitrogen can freeze the remains quickly enough, but it will crystallize the liquid in the cell tissue. Although there is no damage on the surface, the crystallization in body fluids will puncture cells and damage various organs of the human body, making it impossible for him to revive. The person in charge of the relevant agency only said that "it seems that his body has been kept at a relatively low temperature" and did not give any answer about the resurrection time at all.
Resurrection is an illusion that even modern technology cannot realize. A few years ago, a woman writer in China volunteered to donate her body to this institution. Although modern technology has made some progress, vitrification of tissue fluid can be a simple, rapid and effective method to preserve surviving cells, tissues and organs in cryobiology. When cells are preserved by vitrification, the water inside and outside the cells will not form crystals, and the cell structure will not be destroyed, so the cells can survive), which will prolong the time of tissue preservation without being destroyed. However, in fact, only the writer's head is preserved (or only the head is preserved independently), and modern technology can not realize a brain transplant operation that can restore all functions without injury. It is unrealistic to save the head and hope for resurrection, at least for now.
Resurrection of the human body is not as simple as thawing. The dead man's brain has stopped moving, and how to restart the brain's function is the most important thing. Modern people's research on the formation mechanism of consciousness is still unclear, and this cannot be guaranteed. The only case of "resurrection" in modern times is that a Russian team successfully "resurrected" a simple creature that was frozen under the frozen soil for 42,000 years like a worm (they did not die themselves, which is different from being resurrected after being frozen). From worm with simple structure to human body with complex structure, the resurrection technology still has a very, very long way to go. Perhaps this is just a dream of Conan.
