1967 who knows about the abduction of American livestock by aliens?

On May 15, 2006, according to the Russian Morning Post, the first company providing cryonics service in Russia started its own business. The brains of the two victims were "immortalized" in a giant refrigeration facility in the suburb of Zele Nograd. In China, it is said that in August 2005, the "Cryopreservator" was successfully developed and won a national patent. The news further pointed out that the inventor of the cryoresuscitator hopes to preserve Wang Daohan's body for resurrection free of charge; Others even want to use cryonics to resurrect bodies found thousands of years ago ... Perhaps, one day, technology will develop to temporarily suspend life in some way, such as freezing human bodies in containers like large capsules (some terminally ill people always want to freeze themselves), and then bring them back to life after the emergence of technologies to cure their own diseases.

Slowly, Susan woke up from the coma. The first thing that makes Susan feel that there is something is light, followed by the surrounding temperature and humidity. Susan saw the patients around her, but she was very surprised by what she saw. In the ward, hundreds of naked bodies are hanging in the air 120 cm above the ground. When Susan approached these bodies, she saw that these bodies were covered with all kinds of wires with metal traces, some were complicated blood transfusion catheters, and some were all kinds of probes. To Susan, these bodies are like a group of marionettes. "We store them in places where there is less ultraviolet radiation," said the hospital staff around Susan. "This is more conducive to controlling the growth of bacteria and keeping the skin intact. Modern medicine and medical standards have the ability to keep these human bodies alive forever. " The above scene comes from the work "Coma" by American novelist and doctor Rubin Cook. He is a literary pioneer who is keen on describing the end of life. From 65438 to 0977, he was inspired by the story of a man in a manor smuggling the human organs of a coma. For a long time, although human life has ended, the description of being frozen and surviving basically belongs to the category of science fiction.

Today, 30 years after the novel was published, we finally found a new technology that can keep organic life in suspension. However, unlike the dark attempt described in Cook's novels, life research is suspended to help cure those who have serious diseases. Preserve the donor's organs in good condition for organ transplantation; To fight an incurable disease. We expect that in the future, when science and technology develop to cure a terminal illness, or as those science fiction writers imagine, we will sleep for decades in the long interstellar travel and wake up at our destination.

The rapid development of modern empirical science, on the one hand, cruelly shattered people's dream of longevity, on the other hand, under the magical effect of people's strong survival instinct, took on the important task of exploring the road to longevity. The research of modern genetic engineering, as well as the exploration of freezing technology and organ transplantation, are tenacious manifestations of human desire for eternal life.

For those who believe in freezing technology, the eternity of individual life is not a myth. They expect that through freezing and transplantation, human life can break through the time limit, avoid disasters and diseases and survive forever. Some scientists believe that the low temperature environment will significantly reduce the metabolic activity of living tissues. When the outside temperature is low to a certain extent, the cells of the body will neither age nor degenerate, but will be in a state of "life opportunity pause", thus sealing life forever. It is generally believed that the temperature range of life stopping activity is-15℃ to -50℃. Once you can successfully cross this critical temperature range, no matter how long it is frozen, life will be preserved, and once it is thawed, it is possible to revive.

Hello, I'm here to refrigerate.

Philosophers say that all the efforts of life and the creation of all the achievements of human civilization have one purpose: to fight death. Some terminally ill people are eager to refrigerate themselves before death, hoping that one day new skills will enable them to open their eyes again and feel the colorful world.

1967 65438+1October 12, James Bedford, a 73-year-old man, was about to die of lung cancer in a nursing home in a primary school in Los Angeles, USA. There are several members of the Los Angeles Cryopreservation Association at his bedside. Bedford is a physics professor. He has always been interested in cryonics. He donated $200,000 to set up the first cryonics laboratory in Los Angeles. At 6: 30 in the afternoon, his condition worsened and he began to gasp. Soon, his personal doctor announced that he had died.

Cryopreservants quickly connected his body to the heart-lung machine and provided him with nutrition and oxygen to protect his brain from further damage; At the same time, heparin is injected into the body to prevent blood coagulation. Then, they injected dimethyl sulfoxide (DMSO) into the blood, which has antifreeze effect and can prevent the formation of ice crystals in living tissues. Next, the cryologists put the remains in dry ice (solid carbon dioxide), let the body temperature slowly drop to near freezing point, and then turn off the heart-lung machine. At midnight, the body temperature is kept at the temperature of dry ice (-100F, equivalent to about -74.5℃). At this time, the cryostat designed by California engineers was carried into the room. The container is made of polished stainless steel and has a double inner wall (like a thermos bottle). The scientists wrapped the body in aluminum foil, put it in a container and sealed it. Finally, cryologists filled the storage cavity with liquid nitrogen, and its temperature was -320F (equivalent to-197℃). As a result, Bedford's body became as fragile as glass in a few seconds. A few days later, the container containing his body was airlifted to a laboratory in Arizona, waiting for the day when advanced cancer can be treated and there is a way to revive the newly dead body and tissue.

At present, there are at least four organizations in the United States specializing in the business of freezing corpses, among which the Alcoa Life Extension Foundation is the most famous. Alcaud has 78 1 members, and 7 1 members have been refrigerated. Every volunteer signed a contract with Alcord to refrigerate the body before he died. According to the online introduction, Alcaud Life Extension Foundation is a non-profit tax-exempt organization in Los Angeles. Its research purpose is to freeze the living human body at extremely low temperature until the day when science can safely thaw.

According to the person in charge of the institute, what they do is not to store the bodies in the morgue-they don't need dead bodies, just as organs donated by organ donors must be alive. Cryopreservation refers to ensuring the survival of the brain after the patient's heart stops beating and the doctor declares him legally dead. Therefore, the object of cryonics does not include those brain-dead patients.

The freezing process began after the patient's heart stopped beating and was declared legally dead-with the help of instruments, the blood circulation was restored for the patient, so that the patient was almost the same as the living: although the patient to be frozen was judged legally dead, he was still alive in biology. These people need a lot of special drugs to prevent ice crystals from piercing cells and tissues. Alcord believes that "cardiac arrest 100 years ago is irreversible. Once the heartbeat stops, it is considered dead. It is now confirmed that death occurred 4-6 minutes after cardiac arrest, because it is difficult to recover the human brain after this time, which is medically called brain death. But in some experiments, it is found that the heartbeat can stop for 10 minutes without damaging the nervous system. In the future technology, molecular repair technology can extend the limit time of rescue to one hour. By then, the existing criteria for judging death will become a thing of the past. "

In order to bring back the dead, 6.5438+0.2 million yuan was refrigerated by the human body?

Since 1967 realized the first frozen preservation, hundreds of people have implemented this "immortality" method, and thousands of people have been rushing for freezing in legal and economic affairs. If you are thinking about freezing yourself, you should think ahead. Just freezing a brain will cost you $80,000 (about RMB640,000), and on the day of resurrection, Alcaud will make a new body for you to carry your brain. If you want everything to be the same when you are resurrected, you have to pay nearly double the price, that is, 6.5438+0.5 million US dollars (about 6.5438+0.2 million RMB) to Alcaud. If you are a guest from China, the cost will be higher than $6,543,800+500,000 due to other related services. Nowadays, in the intensive care unit of Alcod, many people choose "hibernation" because of modern incurable diseases.

In addition to medical applications, this long sleep will also be widely used in long-term space travel. This is not only to pass the long and boring time, but also to save the consumption of water and food. Similarly, if a soldier is injured in the war, he can "hibernate" until he retreats.

Another possibility is to stop the heartbeat and empty the blood in the body through complicated surgery, which was put forward by Peter Safa, who died at the University of Pittsburgh. The experiment of emptying blood in the body before operation was initially carried out on 14 dogs. The researchers replaced the blood with saline solution, so that the heart rate and pulse of these dogs became weak. After an hour's pause, these animals were injected with blood again-they came back to life. Research shows that only half of the dogs' nervous system is damaged. However, they only survived for 72 hours. Other researchers have done similar experiments with pigs. These experiments provide us with a lot of useful information, but there are still considerable risks in applying them to the human body.

Will one day, if someone wants to freeze himself, they just need to go to the local hospital and sign a contract? Can we start sleeping in 2006 and wake up a century later? For the human body, there is no example of resurrection after freezing. However, this is the name of the Pleistocene (geological age, also known as Pliocene). About 1 10,000 years to 2 million years ago), the answer is yes. This microorganism has been sleeping for 32,000 years since it was frozen in a pond in Alaska-until it was reactivated by an astrobiologist at NASA. This is also the first time that microorganisms that are still alive have been found in ancient ice. After thawing, messengers from ancient times began to move under the microscope. Maybe it is thinking: Why is its sleep suddenly interrupted?
