During this 17-hour space journey, the chief never rested, and Zhang Wei was naturally embarrassed to rest, so when the "Future" spacecraft returned to Earth, he ignored the reporters who asked him questions, went directly to the scientific research building, and fell asleep.

It's so tiring.

When he woke up, it was already more than five o'clock in the afternoon, he finished washing, got dressed, and habitually activated the dark blue 1 to see if there were any missed calls.

As soon as the dark blue 1 was started, the intelligent assistant Xiaolan prompted him, and his mother left him a holographic video message.

Zhang Wei immediately asked Xiaolan to play this holographic video message, it turned out that his mother asked him to go home for dinner at night, and said that he had something to discuss with him.

"What could it be?"

Zhang Wei couldn't help but be a little curious, and then took two intelligent robot bodyguards and drove the flying car to the villa where his parents lived.

The dinner is very rich, the meals are made by my mother herself, which is also Zhang Wei's favorite taste, although the meals made by the intelligent robot are also very good, but there is always a little less taste of home.

"Mom, what do you want to tell me?"

After dinner, Zhang Wei asked.

"Of course it's your marriage, in less than five months, you and Xiaoyu will get married, and you should start preparing. ”

The mother smiled, she had been looking forward to her son getting married soon, and then she would hug her grandchildren, and now she was finally looking forward to it.

"It's more than four months away, does it need to be so early?"

Zhang Wei was surprised.

You think that a wedding is as simple as inviting relatives and friends to have a meal and a drink, and there are so many things. ”

My mother crossed her fingers and said, "You have to decide in advance the date, scale, form, and style of the wedding, determine the wedding budget, draw up the guest list, determine the best man and bridesmaid, determine the officiant and witnesses, determine the wedding venue, wedding hotel, wedding company, customize the dress, and distribute the invitation ......."

My mother talked for more than ten minutes before she finished speaking.

Zhang Wei listened to it with a big head, and found out for the first time that marriage was such a troublesome thing, but this is a major event in his life, and he can't be sloppy in the slightest. Not only should it not be sloppy, but it should also be done beautifully.

At this time, my mother said, "You don't have to worry about the details, you can ask a professional to deal with it, you just need to tell them what you like, but the guest list, the best man and bridesmaid, the officiant, and the witnesses all need you to determine." ”

When Zhang Wei heard this, he immediately breathed a sigh of relief, and hurriedly promised his mother that he would deal with this matter as soon as possible.

After returning to the villa where he lived, 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, and at that time, he decided to make his wedding a wonderful wedding of the century, and it had to be different.

How do you stand out from the crowd?

Zhang Wei thought about it for a long time, and suddenly his eyes lit up, if this wedding is held on the moon, it cannot be said that there is no one to come, but it is definitely unprecedented, and it will definitely make everyone including him and Ren Huaiyu unforgettable!

That's it.

The corners of Zhang Wei's mouth hooked up a smile, such a tall wedding, now only he has the ability to have, because other people can't even go to the moon. In addition, since it has been decided to hold a wedding on the moon, it must not be allowed to be held in an open field, it seems that it is necessary to build a building on the moon for your wedding, as for the name of this building, it will be called Guanghan Palace!

After two more days of busy work, Zhang Wei finally made the preliminary preparations for the wedding, and at this time, he received good news from Dr. Summit, who made a major discovery in the process of studying alien blood.

Future Technology Company, Experimental Base, in a laboratory.

"Dr. Summit, you're saying that this alien might be a race with a lifespan of more than five thousand years?"

Zhang Wei, wearing a white coat, looked at Summit in front of him and asked.

"Doctor, you know that the lifespan of a human being is related to the number of cell divisions. ”

Summit said excitedly.

Zhang Wei nodded, his knowledge reserve was extremely rich, and he naturally knew this.

This idea was put forward by the American scholar Helverly in 1961. Based on experimental research, Helverey found that the number of divisions of animal embryonic cells is regular during the growth process, and senescence 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 lifespan.

Here's how Hellfly's experiments were: he put the cells of the fetus in a culture medium and divided again and again, multiplying generation after generation, but when the cells divided to 50 generations, the cells all senescent and die. On the basis of a large number of experimental data, he proposed to estimate the lifespan of a human being based on the number of cell divisions, and the average cycle of each division of human cells is about 2.4 years, according to which the human life expectancy should be 120 years. The number of cell divisions in chickens is 25 times, the average cycle of each division is one year and two months, and its lifespan is 30 years. The number of divisions of mouse cells is 12 times, the division cycle is 3 months, and its lifespan is 3 years.

Summit said excitedly, "After I tested and analyzed the alien cells you provided, I found that alien cells are very similar to human cells, with almost identical structures and division cycles similar to human cells. In subsequent experiments, I used hormones to stimulate alien cells to speed up division, and finally got a surprising discovery, alien cells will not age and die until 2100 generations, which means more than 5000 years of life. ”

"Can divide up to 2100 generations, it should be related to telomeres and telomerase, Dr. Summit, have you tested telomeres and telomerase in alien cells?"

Zhang Wei asked.

Telomeres are things that exist in the nucleus of humans and some animals with a hat-like at both ends, and it is actually a DNA ~ fragment. Scientists have found that every time a cell divides, the telomeres shorten a little, and when the telomere length is shortened to a certain extent, the cell will stop dividing, leading to aging and death. Therefore, some scientists believe that telomere length determines the lifespan of organisms, and the longer the telomere, the longer the lifespan.

In the course of their research, scientists also discovered the presence of a special reverse transcriptase, telomerase, in cells. The presence of telomerase can repair the defect of DNA replication, so that telomeres will not be lost due to cell division, so that the number of cell divisions increases. Therefore, the more active telomerase is in the cell, the more the length of the telomeres can be maintained.

Based on these findings, some scientists believe that if telomerase can be kept high in activity, the length of telomeres can be maintained, and the process of cellular aging will be delayed, and even human beings will be immortal.

Ronald Debinho, a tumor doctor at Harvard University in the United States, successfully reversed the aging process for the first time through a mouse test based on the telomere theory. In the experiment, Debinho used a special method to prematurely age the mice, making the skin, brain, internal organs and other organs of these animals similar to those of an 80-year-old, and then using drug stimulation to successfully revive the telomerase reverse transcriptase. After taking the drug for 2 months, the mice grew a large number of new cells, rejuvenated and rejuvenated. What is even more surprising is that the old male rat has regained its fertility and reproduced offspring.

However, there is no such thing as a free lunch. Using this method to slow down aging may also increase the risk of cancer. Studies have shown that increasing the activity of telomerase in mice makes them more susceptible to skin cancer and breast ~ adenocarcinoma.

As far as Zhang Wei knows, there are also international pharmaceutical giants who have studied anti-aging agents based on telomere theory, but the experimental results are disappointing: "The experimental subjects have grown many deformed organs. "In the end, the project had to be cut, and the experimental data was sealed without being disclosed to the outside world.

This is also the reason why Zhang Wei has not considered the telomere theory when he studied gene evolution fluid before. (To be continued.) )
