, from ancient times to the present, some princes will really exist in the pursuit of longevity? It just does not exist on people, but lobster. It is said that the lobster won't die as long as it doesn't eat it. Is this true? Can lobster really live forever?
Lobster Eternal Secret
What do you think determine the length of life? Many people think that the life of life is related to cell division . When the number of cell divisions reaches a certain upper limit, we stop working, and our lives will end. This can affect cell split substances. We are called "telomeres".
is attached to the chromosomal, mainly to protect the chromosomal, which can prevent dna disorder during disintegration and replication, thereby maintaining the stable of DNA. However, when the cells are divided, the telomeres are damaged. Over time, when it is worn to not support cell division, the death comes.
But lobster is different from people. Although their telomeres are worn, they can be supplemented by themselves during cell division. It is not being killed and suffering from humans. Of course, it is important to emphasize that telomeres are just a hypothesis, which has not been completely confirmed, but has been widely recognized.
gene
telomere is damaged to a certain limit, creatures will die. but biological contains a thing called " telomerase ". It can extend the telomere, restore the length of the telomere, and give the telometer to life. has more organic organisms, the more you can renew, the more likely it is to achieve eternal life.
is just that there are not many active telomers in people and many animals, so their life span is limited, but in lobster body, they have many active telomerase, so they can keep cell division and molting growth. Unfortunately, their hearts and brains have no telomerase to help update. Once these core parts are damaged or aged, they will still die.
is currently the most famous longevity lobster called George. In 2008, it was captured by humans in Finnish . It is reported that its life span is about 140 years old , which was nearly 20 catties at that time. But is so old that it looks very healthy . Except for George, humans did not find a few longevity lobster. If the theory of lobster longevity is correct, should we see lobsters of 100 and 200 years of lobster? This shows that even if the lobster can be divided infinitely without telomeres, they are not hindered, but is still bound by nature, and may die for some reason after reaching a certain age. What is the reason for
?
has found that most of our organisms will be damaged through research on telomeres. This is to keep DNA stability and avoid cancer in cells in the body. The more times the DNA split, the disorderly phenomenon will become more and more common.
So lobster it has the ability to infinitely divide cells, but it will also cause some cancerous due to disorder. And cancer is also greatly threatened to their life span. The longer they live, the higher the chance of cancer. All in all, even if there is no natural enemy, they will have the risk of cancer after a certain age, which is also a ghost gate that they must go in life.
actually has an important reason for lobster death: shelling. Lobster's body will have a layer of hard shell to protect them. However, these shells will not grow with the lobster, but they will molt the shell after each period of time. Re -grown new shells to accommodate their larger body shape. However, the difficulty of molting is also positively related to the body shape. The larger the lobster, the more difficult it is to molt. may be exhausted or injured during the shelling process. Therefore, nature is actually controlling the lobster life in the underworld.
If this gene is copied to the human body, can humans achieve eternal life?
Of course, at present human beings cannot do eternal life, and the number of divisions of our cells will decline, unless the cells can split infinitely or return to their initial state. However, it is mentioned above that the upper limit of the number of cell divisions is currently speculated that the length of chromosomal telomere is determined by the length of chromosomal telomere, and this lobster can theoretically be eternal because the split will not consume telomeres. If the principle can be investigated, human beings may not be eternal.
, but human has a cell that can be divided infinitely. It is cancer cells. The problem with unlimited division is a headache. Assuming that a cell can be split 7 times, each division requires 1 unit of energy, then it needs to consume at least 1+2+4+8+16+32+64 = 127 unit energy. Each division is divided once, and the next division is needed before the previous division. Two times the energy, if this cell is a cancerous cell, can divide infinitely, how much energy does it need to divide twice more times? (In other words, this column is very interesting. Each energy required for each division is the total amount of energy consumed before.) In other words, if human beings can control cancer cells, human beings can theoretically obtain eternal life.
is currently very simple to achieve eternal creatures. Human beings can not have eternal life as a complex creature. Don't have a dream of eternal life. It's unlikely to eternal life. I heard that the high speed will distort the surrounding space. In the process, the internal time and the external time flow rate are different, similar to time and space crossing. However, this effect is minimal. Unless it reaches the speed of light, human beings do not reach the speed of light. In case one day the technology is really realized, are you willing to live forever? In short,
is not conducive to human reproduction and development, and the disadvantages are greater than benefits. In addition to lobster, lighthouse jellyfish jellyfish and some sailor found in waters in are confirmed to have the ability to " Youth". It can theoretically be able to live in theory, and it is emphasized that it can only be theory.
We look at nature. has this "longevity" ability creature that is often concentrated on some low -level creatures. On the road of natural evolution, , senior creatures choose to continuously optimize the individual capabilities in the ethnic group at the cost of abandoning longevity, thereby achieving the comprehensive development of the ethnic group. Death is not terrible, what is terrible is the decline of a ethnic group.
