(2) Tell me something about the history of science and technology about whether people can live forever ~
Ask who is carefree in the world, only the fairy is at ease. The immortals who live in Luotian are immortals and immortals, so there is nothing to worry about in the fairyland. Mortals in the world of mortals, living in the border, want to live and die, endless life, gain and loss. For immortals, fame and fortune in the world is only a fleeting moment in the long river of time, and only the soaring purple mansion among immortals is the eternal pursuit. But common sense tells us that human beings cannot escape the fate of ultimate death. However, people are always unwilling to face this dark truth, and they are more willing to believe in the myth of immortality. Ordinary people seem to be more inclined to pursue the so-called "fountain of youth", and some people are constantly exploring in the fields of science and medicine.
Scientists are also committed to studying the characteristics of many compounds in order to find out the factors that prolong life, such as resveratrol (a substance found in grapes), rapamycin (a bacterium extracted from Easter Island) and protein composed of p2 1 gene. These protein can inhibit other protein from forming amyloid plaques in cells, which are related to Alzheimer's disease and may promote cancer. It is reported that in 2000, Nekes Biotechnology Company was developing a drug that could achieve a certain degree of inhibition. The researchers also continue to analyze an enzyme called telomerase, which can slow down the process of telomere atrophy. Telomere is a kind of DNA sequence, which will gradually shorten during cell division until the cell eventually mutates or dies. The 2009 Nobel Prize in Medicine was awarded to the discoverer of the working principle of telomere and telomerase. Recent research results also confirmed the function of telomerase. In a study published in the journal Nature on June 20 10, 1 1, mice were transplanted after telomerase was extracted, and this process miraculously rejuvenated. Technically, people can improve the level of telomerase in the body in various ways several years ago, but this technology has not been clinically evaluated so far. At the same time, two compounds that have been tested in humans have been put into use this year. These two compounds are SIRT 1 and STACs, which are two synthetic catalysts and can simulate the thermal confinement effect. Experiments on many species show that this effect can slow down metabolism and alleviate the aging process. According to David Sinclair, a pathologist at Harvard Medical School, the species tested include yeast and primates. However, Jay Orshanski, a professor of epidemiology at the School of Public Health of the University of Illinois in the United States, believes that overcoming the problem of aging cannot be achieved by only one drug. Orshansky said, "Resveratrol, telomerase and p2 1 genes are largely superficial. In the past 10 years, no drugs can interfere with and alleviate the problem of human aging. " Orshansky insists that the genes of people over 100 have a special function, that is, they can limit the aging process. "New England Centenarians Research" is the largest project dedicated to the elderly in the world. At present, the project is tracking about 65,438+0,600 centenarians and their hundreds of children. Orshansky was not involved in the study, but he thought, "The reason why this study is so exciting is that we haven't seen the results in many species. We expect to see that the human body can also alleviate aging like a mouse, thus achieving a huge theoretical leap. The secret of longevity seems to be coming to us. " Scientists believe that the ultimate "fountain of youth" may not be realized by chemical or biological methods, but by technical means. Futurist ray kurzweil predicted that nanotechnology may be one of the means to achieve immortality. Micro-robots based on nanotechnology can go deep into our bodies and repair damaged organs and tissues, thus prolonging patients' lives.
(3) Talk about the pursuit of immortality by historical figures in the past. Both Qin Shihuang and the Monkey King longed for immortality. They ate a lot of Dan medicine, Xiantao and human flesh, and did many strange human sacrifice ceremonies, but they all failed. Rich people accumulate virtue and do good deeds, hoping to get enlightenment from the gods. On the other hand, civilians are more interested in offending religion and soul. Of course, there are some perverts who eat human brains. Egyptian pharaohs even donated their own bodies to be mummified, so that their bodies would not die and their souls would come back one day. Soldiers in ancient battlefields were often cheated. Their boss lied to them that if they die on the battlefield, they can only go to heaven or go to hell, so stupid soldiers fight to the death. The Japanese believe that eating fish by monks (nuns) is the way to live forever. Of course, another part of the Japanese people are dismissive of this. They think that death is normal, so they cherish life more, and the good times will not last long. Oh, let a brave man take risks where he wants to go. Of course, this is their view in the Tang Dynasty, which also led the Japanese to prefer murder and fornication. In a word, what they pursue is actually spiritual immortality and eternity, which is really a mystery. With the progress and development of mankind, it was not until the Qin Dynasty that immortality was put into practice for the first time. Out of greed for supreme power and inexhaustible wealth, Qin Shihuang dreamed of immortality. In order to realize his dream of immortality, Qin Shihuang really sent Xu Fu to lead thousands of virgins to the East China Sea to beg for elixir for him. As a result, I didn't get the elixir, and Xu Fu and others disappeared without a trace. Later, an alchemist said that he could refine the immortal elixir for Qin Shihuang. Qin Shihuang believed it and spent a lot of manpower and material resources to ask the alchemist to refine the elixir for himself. As a result, Qin Shihuang was cheated and the alchemist was killed. Qin Shihuang's pursuit of immortality ended in failure. Influenced by Qin Shihuang, Emperor Wu of the Han Dynasty also made the same mistake. He sent someone to make a 30-foot-high exposed dish with a circumference of 17 feet out of copper. It is said that taking the dew-mixed jade chips received from this dew tray can realize people's longevity. The same result, Emperor Wu of the Han Dynasty also ended in failure. Although Qin Shihuang's cultivation of immortals was unsuccessful, it had a great influence. Because of his actions, many legends about the elixir of life spread around the world. Some people say that taking elixir can prolong life; Some people say that eating the fruit of life can lead to longevity; Others think that eating mica tablets can prolong life and so on. It is because of these legends that many emperors in China, such as Yang Di Yang Guang, Emperor Taizong Li Shimin, Tang Xianzong Chunli, Tang Muzong Hengli and Ming Shizong Zhu Houzong, were poisoned by taking elixirs containing mercury and lead. The emperors failed in their pursuit of immortality, so it is impossible for the world to evaluate immortality. In addition, there are no immortals in real life, so people believe that it is absolutely impossible for human beings to achieve immortality, and immortality is against the law. But with the development of genetic technology, maybe the future human beings can live forever.
(4) Although all the above shows that longevity is something that can be met but not sought, the landlord should not be too depressed and remain optimistic. At present, scientists are studying, and there are also expectations for the birth of robots in the next 20 years. We will live like that forever, haha ~ Come on, always have a present heart and a young heart ~ ~
