Yuan Haochen smiled slightly: "You are worthy of being the most famous life scientist in the alliance!" I'm sure you've noticed! ”

"Hohoho~" Dr. Minchi said with a smile, "Indeed, I found out that you were unusual in the media live broadcast yesterday. Pen "Fun" Pavilion www.biquge.info"

"Flying close to the speed of light and long periods of hibernation can slow down your aging rate, but there is a clear difference in your appearance from another astronaut."

"I'm aware of that, too!" Hara said frankly, "Maybe other people think that it is related to flying close to the speed of light and sleeping for a long time, but I don't think it's that simple!" ”

"Could it have something to do with Roland's invasion?" Dr. Minchi asked rhetorically, he also participated in the Mars scientific exploration operation with Yuan Haochen back then, and he also knew the details of Commander Roland, that is, Genesis AI 8.

"I'm not sure about that!"

The invasion of alien artificial intelligence is indeed one of the factors that Yuan Haochen considers, after all, the body of Commander Roland, that is, Princess Hanyue, has really survived for a long time of 2,000 years.

However, in addition to this, Yuan Haochen had another option in mind, and that was the mysterious meteorite energy found in the waterhole by the Sun Moon Stream. Since it has the ability to change and strengthen its thinking ability, observation ability, reaction ability and even the strength of its body, it is not impossible to delay the speed of aging!

"You look exactly the same now as you did when you left Earth!" Dr. Minchi said in amazement.

"Do you have any opinions? Please give me some advice. Yuan Haochen humbly asked.

"Can you give me some blood and a few histiocytes?" Dr. Minch didn't answer his question, but asked suddenly.

"It's ......, no problem." Yuan Haochen's mind turned quickly, and with his understanding of Dr. Mingqi, he felt that there was nothing wrong with it, so he agreed.

"Hohoho~" Dr. Minchi laughed again, "Don't worry, we won't slice you into research!" ”

Yuan Haochen shook his head with a wry smile, and complained in his heart: "Sure enough, it's a Frankenstein!" ”

With his current ability and status, he certainly wouldn't worry about anyone daring or having the ability to slice it into research. Moreover, the slicing study itself is a very absurd thing.

From another point of view, if you can contribute a part of your blood and a few cells to the research of human life sciences, Yuan Haochen is still happy to do it!

"Hao Chenjun, do you know why humans and most higher animals age?"

Dr. Mingqi asked while bleeding Yuan Haochen, the scene was quite weird.

"This is also a scientific puzzle that has not yet been defined!" Yuan replied, "I have read some books related to it. ”

"Hao Chenjun is worthy of being a super scientist, and he really has a wide range of knowledge!" Dr. Minchi complimented.

"You've won a prize!" Yuan Haochen brought a cotton ball and pressed the punctured arm tightly.

"Do you know how often cells in the human body are replaced?" Dr. Minchi continued.

"Different cells in the human body have different lifespans, some have a lifespan of several months, but some only have a few minutes or even less. For example, liver cells have a lifespan of 18 months, while skin cells and the cells of the digestive tract wall have a lifespan of only a dozen days. There are also some cells that can exist for a lifetime, such as nerve cells, skeletal muscle cells, and cardiomyocytes, all of which are permanent cells. Yuan Haochen replied.

"You're right, people of different ages have different rates of cell turnover." Dr. Minchi adds, "According to cell algebra (also known as cell division submathematics), human cells are completely new every 2.4 years. ”

"In addition, you must have heard that there is a certain limit to the replication lifespan of every type of cell." Dr. Minchi continued, "We have improved cell culture experiments, but the effect is not obvious, under artificial culture conditions, even the best culture methods cannot change this established fate, for example: human fibroblasts can only reproduce for a maximum of 50 generations (according to the relevant theory, the human lifespan range is about 2.4 years x 50 = 120 years. At that point, the cell will inevitably die. Other species, such as murine fibroblasts, can only divide for 19 generations, and tortoise fibroblasts divide for 110 generations......"

"Dr. Minchi, you don't want to take my cells and grow them, haha!"

"You're right, that's what I mean!" Dr. Minchi replied with a twinkle in his eyes.

"Then you can train for a few more generations, which means I can live a few more years!" Yuan Haochen quipped.

Soon, Dr. Mingqi was satisfied with the blood drawn from Yuan and a few tissue cells, just like an ordinary physical examination.

"However, not all cellular organisms are subject to the number of cell divisions." "Single-celled organisms such as bacteria and protozoa, which have always relied on cell division to reproduce their offspring, have never stopped for hundreds of millions of years, and there seems to be no problem of cell aging. Moreover, in higher organisms, there are exceptions, such as: germ cells and cancer cells. ”

The phenomenon of uncontrolled germ cell division is strange and well understood. Imagine that the union of your parents' germ cells gives birth to you, and you are a whole new individual. That is to say, at the time of your birth, the life clock of your parents' germ cells has been accurately set back to zero, so as to avoid the tragedy that your life expectancy is destined to be twenty or thirty years shorter than that of your parents.

As for cancer cells, it seems that there is also a miraculous mechanism that helps them get rid of the doom of eventual aging. Biologists have found in culture that cancerous cells can multiply indefinitely, from generation to generation, and do not tend to age like normal cells at all. In clinical medicine, it is precisely because cancer cells are immortal and divide recklessly that cancer patients eventually die.

"This is the wonderful place of life!!" Dr. Minchi exclaimed, "The microcosm of life is as great as the macrocosm of the universe!" ”

"The day is in full swing, the moon is waxing and waning, and the same is true of the individual's growth, from weakness to maturity, and finally to aging. So, how long should humans live? ”

Dr. Mingqi is really familiar with Chinese culture, and quoting scriptures and classics is the first way, which is also what Yuan Haochen has a good impression of him.

"In the natural realm, although the matter we see is eternal, the vast majority of things have their own lifespan. Radioactive elements have a half-life, living beings are born, old, sick and die, and even society will have ups and downs. I believe that with the development of science and technology, molecular design and genetic design will become possible, and human beings may have the ability to reinvent themselves in the future, and aging and disease will be conquered. Perhaps the use of genetic technology will make future human beings more powerful, more muscular, and more responsive......" Yuan Haochen looked forward to the future of mankind and thought about it.

"Hao Chenjun, do you really dare to think that with our current scientific level, it is already great to be able to fight aging and prolong the life span of human beings!" Dr. Minch said.

"So, why does the human body still age when cells are constantly being renewed?" Yuan Haochen continued to ask.

"As humans age, their hair slowly turns gray, their skin becomes wrinkled, their muscles loosen, and their bones become brittle...... Every part of the body is quietly changing. Aging is an extremely complex process. This complexity has led to at least 300 theories of aging currently in place. Dr. Minchi said seriously, "I thought aging had something to do with evolution!" ”
