During the 17 hour space trip, the chief didn't rest, and Zhang Wei was embarrassed to rest. So when the "future" spacecraft returned to earth, he ignored the reporters who asked him questions, went directly to the research building and fell asleep.
Too tired.
When he woke up, it was more than five o'clock in the afternoon. After washing and dressing, he habitually activated dark blue 1 to see if there was any missed call.
Dark blue 1 just started, intelligent assistant Xiao Lan prompts him, and his mother leaves him a holographic video message.
Zhang Wei immediately asked Xiaolan to play the holographic video message. It turned out that his mother asked him to go home for dinner at night, and said that he would discuss something with her.
"What will it be?"
Zhang Wei couldn't help being curious. Then he took two intelligent robot bodyguards and drove the flying car to the villa where his parents lived.
The dinner was very rich, and the meals were all made by my mother herself, which was Zhang Wei's favorite taste. Although the meals made by intelligent robots were also very good, they were less like home.
"Mom, what can I do for you?"
After dinner, Zhang Wei asked.
"Of course, it's your marriage. In less than five months, you and Xiaoyu are going to get married, and they should start to prepare."
The mother said with a smile, she had been expecting her son to get married quickly, and then she held her grandson and granddaughter, and now she finally had to look forward to the end.
"There are more than four months left. Is it necessary to be so early?"
Zhang Wei was surprised.
"Where is it early? It's not early! You think the wedding is to invite relatives and friends to have a meal and drink wine together. There are so many things. "
"You should decide the date, scale, form and style of the wedding in advance; determine the wedding budget; draw up the guest list, determine the best man and bridesmaid, determine the principal and witness; determine the wedding venue, wedding Hotel and wedding company; customize the dress; send out the invitation..." my mother said
Mom talked for more than ten minutes before she finished.
Zhang Wei was very big. He found that marriage was such a troublesome thing for the first time. However, it was a big event in his life, and he could not be careless at all. Not only can't be sloppy, but also do it beautifully.
At this time, the mother said, "you don't need to worry about the details. You can ask professionals to deal with them. You just need to tell them your appeal preferences. However, you need to determine the guest list, best man and bridesmaid, principal and witness."
Hearing this, Zhang Wei took a breath of relief and promised his mother that he would deal with it as soon as possible.
After returning to his villa, Zhang Wei began to seriously consider his wedding.
At the beginning of the year, he attended the weddings of Liu Hai, Qin Xiaobu and Zhang Zhijian. At that time, he decided to make his wedding a wonderful century wedding, which must be different.
How to be different?
Zhang Wei thought about it for a long time, and suddenly it came to light. If this wedding is held on the moon, it can't be said that it's the last one, but it's absolutely unprecedented. It will be unforgettable for all people including him and Ren Huaiyu!
That's it.
Zhang Wei has a smile on his lips. He is the only one who can have such a big wedding now, because other people can't even go to the moon. In addition, since we have decided to hold a wedding on the moon, we must not let the wedding take place in the open field. It seems necessary to build a building on the moon for our wedding. As for the name of the building, it is called Guanghan palace!
After another two days of busy work, Zhang Wei finally made preliminary preparations for the wedding. At this time, he received good news from Dr. samit, who made a major discovery in the research of alien blood.
Future technology company, experimental base, a laboratory.
"Dr. Sumter, you mean this alien could be a race that lives more than five thousand years?"
Zhang Wei, dressed in a white coat, looked at samit in front of him and asked.
"You know, doctor, that human life span is related to the number of cell divisions."
Said samit excitedly.
Zhang Wei nodded, his knowledge reserve is extremely rich, nature knows this.
This point of view was put forward by American scholar Hale Foley in 1961. According to the experimental research, hefferley found that in the process of growth of animal embryonic cells, the number of times of division is regular, and aging and death occur at a certain stage. This is related to the number and cycle of cell division. The multiplication of the two is its natural life span.
Here's what hefferley did: he put the cells of the fetus in the culture medium to divide again and again, to reproduce generation by generation, but when the cells split to 50 generations, they all aged and died. On the basis of a large number of experimental data, he proposed to calculate the life span of human beings according to the number of cell divisions, and the average cycle of each division of human cells is about 2.4 years, according to which the life span of human beings should be 120 years. The number of cell divisions in chicken is 25, the average period of each division is one year and two months, and its life span is 30 years. The number of mouse cell divisions was 12, the division cycle was 3 months, and the life span was 3 years.
said, "as like as two peas, I have been testing and analyzing the alien cells. I found that the alien cells are very similar to human cells. The structure is almost the same, and the splitting cycle is almost the same as human cells. In the later experiments, I used hormones to stimulate alien cells to speed up their division, and finally got a surprising discovery that when alien cells divide to 2100 generations, they will age and die, which means more than 5000 years of life. "
"It can divide to 2100 generations. It should be related to telomere and telomerase. Dr. sumit, have you tested telomere and telomerase of alien cells?"
Asked Zhang Wei.
Telomeres, which exist in human and some animals, have a cap at both ends of their nuclei. They are actually DNA fragments. Scientists have found that every time a cell divides, the telomere shortens a little. When the telomere length shortens to a certain extent, it will stop cell division, leading to aging and death. Therefore, some scientists believe that the telomere length determines the life span of organisms. The longer the telomere, the longer the life span.
In the process of research, scientists also found that there is a special reverse transcriptase in cells - telomerase. The existence of telomerase can repair the defects of DNA replication, so that telomere will not be lost due to cell division, and the number of cell division will increase. Therefore, the more active the telomerase in the cell, the longer the telomere can be maintained.
According to the results of these studies, some scientists believe that if we can keep telomerase activity high all the time, the length of telomere will be maintained, and the process of cell aging will be delayed, or even make people immortal.
According to telomere theory, Ronald debinho, a tumor doctor at Harvard University, successfully reversed the aging process in mice for the first time. In the experiment, debinho used special methods to make mice age ahead of time, making the skin, brain, internal organs and other organs of these animals similar to those of the 80 year old. Then he successfully revived the telomerase reverse transcriptase by drug stimulation. Two months after taking the drug, a large number of new cells grew up in the mice, rejuvenated and rejuvenated. What's more surprising is that the old male rat has regained its fertility and reproduced again.
But there is no free lunch. Using this method to delay aging may also increase the risk of cancer. Studies have shown that increasing telomerase activity in mice makes them more likely to develop skin cancer and breast adenocarcinoma.
To Zhang Wei's knowledge, there are also international pharmaceutical giants who have studied anti-aging agents based on telomere theory. However, the experimental results are disappointing: "there are many abnormal organs in the experimental body." In the end, the project can only be cut off, and the experimental data are sealed and not disclosed to the outside world.
This is also the reason why Zhang Wei didn't consider telomere theory when he studied gene evolution fluid. (to be continued. )
