On March 10, Zhou Yu held a Biology Meeting of the Science and Technology Committee in response to the problems discovered by the astronauts.

Participants in the meeting were Wang Xiaoxiao, member of the Science and Technology Committee, director of the Gene Research Institute, and Tao Shengwen, director of the Cell Laboratory.

Neurology expert Chen Jin, traditional Chinese medicine expert Qi Zheng, and internal medicine expert Zhao Tianyuan.

Zhou Yu first spoke: "If you find a problem, you must solve it. We found that astronauts will survive in space, and many sub-health problems will arise in half a year.

If you want to survive on other planets for a long time, you must strengthen the adaptability of the human body to the environment.

Our current technology can only choose whether to genetically transform the human body or cell transformation.

The method of genetic modification is to change the human genetic material and let it express certain proteins with special functions.

Cell transformation is to make the body cells stronger and achieve the purpose of strengthening the body's adaptability by tempering cells."

Traditional Chinese medicine expert Qi Zheng immediately opposed it clearly: "I strongly oppose the method of genetic modification, and cannot allow foreign genes to slander our human gene pool.

Some evil scientists modify infant genes.

She was just changed to a gene locus, which could have extremely terrible consequences.

This altered gene is likely to produce a new genetic disease that pollutes our entire human gene bank.

Hemophilia, albinism and other hereditary diseases all have genetic mutations at a certain gene locus. At that time, it may be just a person's gene mutation.

It turns this disease into a more extensive disease through human reproduction and spread.

This is just a change of a gene locus. Genetic modification of the human body will change thousands of gene loci. I don’t know what terrible consequences will be caused.

It may even be that our decision will directly cause major changes in the gene pool of human populations, and I don’t know what kind of terrible chain reaction will be produced.”

"A bottle is not satisfied, half a bottle is banging. After reading a little popular science article, I thought I had mastered the truth.

This kind of person is to describe someone like Dr. Xiang Qi." Wang Xiaoxiao waited politely until Qi Zheng finished speaking, and he immediately retorted.

“It’s like we use gene editing to solve the hemophilia that has plagued humans for many years.

It is to modify the patient's genes, correct the defects in the patient's genes, and use the hematopoietic stem cells formed by this intact gene to re-transport them into the patient's bone marrow.

This method can effectively cure the hereditary disease of hemophilia.

But if the probability of hemophilia patients cured by this method changes in their children's probability of having hemophilia.

The answer I gave is that there is no change, because we only change the genes of somatic cells, not the genes of germ cells.

We have proven that this genetic modification that can solve the disease is correct. We do not modify germ cells, but choose to modify somatic cells.

We are cautious in using gene editing tools to prevent the balance of human genes from being self-righteous, thus contaminating the entire human gene bank.

To strengthen the adaptability of human body, it must transform the somatic cells of normal humans. We will never touch the taboo of human germ cells.

Our Gene Research Institute has been studying the ability to implement certain gene fragments and has discovered many protein structures with special functions.

I want to find some functional proteins that have positive effects on the human body but will not have side effects on the human body.

From a scientific point of view, it still has certain feasibility.”

After hearing Wang Xiaoxiao say this, Qi Zheng immediately apologized: "This is my mistake. I don't know at all. There are ways to genetically modify human cells but not affect the genetic material of offspring."

Chen Jin also agreed: "Somatic genetic modification is indeed a more feasible method.

Through functional proteins expressed by special genes, it can completely change the state of the human body.

As long as we are sure that this protein will not have side effects on the human body, we can still accept this level of genetic modification.

From birth, our body has injected many heterogeneous proteins, the most common of which are various vaccines and antibodies.

Protein is also one of the commonly used drugs in medical care now, and people still have a high acceptance of this kind of thing."

Zhou Yu smiled and said, "After Director Wang Xiaoxiao's introduction, everyone has a high degree of acceptance of genetic modification.

Now, please ask Manager Tao Shengwen to introduce the basic ideas of cell transformation. Let’s listen to another path that can be realized.”

Tao Shengwen said with a serious expression: "Let me introduce the way of cell transformation.

We all know that people who exercise for a long time must be healthier than those who stay at home for a long time.

This is the long-term tempering of his cells and all the data indicators are far superior to those of ordinary cells.

However, human exercise has its limits on the cell tempering process.

Even if you start practicing since childhood, you will never practice powerful martial arts like that.

Modern martial arts are just an exploration of the human body's strength skills.

It is easy to release the strength of our human muscles reasonably and break a small tree as thick as a bowl.

In addition to the upper limit of exercise tempering, human cells cannot become so powerful.

Another important reason is that the lifespan of cells is very short.

It only takes more than 6 years for a normal person to replace all cells except neuronal cells.

It is the two important reasons, the upper limit of cell tempering and cell lifespan, that limit the self-transformation of human cells.

After a long period of accumulation in our cell laboratory, we have now discovered that under the action of a certain biological energy, cells can be repeatedly tempered.

This quenched cell has a higher strength and longer lifespan. Newly differentiated cells can also quickly complete the quenching, allowing the strengthened cells to continue to maintain."

After listening to the two scientists' narratives, Zhao Tianyuan said in surprise: "As long as you ensure that there are no problems in the human body, these two methods are good choices, and I cannot judge which method is better now."

Chen Jin whispered in Zhou Yu's ear: "Only children make choices, we must of course all of us."

When Zhou Yu heard this, his eyes lit up and decided to make a decision: "We don't know which method will succeed in the end, so we should go hand in hand. Don't give up on both solutions.

Maybe it is the final success of a certain plan, and maybe the two plans work together to produce the effect of one plus one greater than two."

Wang Xiaoxiao gritted the bullet and asked: "Mr. Zhou, if you want to achieve genetic modification, it is extremely dangerous and it is definitely impossible to conduct human experiments.

This is a genetic modification of humans and animal experiments cannot be carried out.

We must use clones, which is the best experimental subject.

But there are great risks in this legal and public opinion."

Tao Shengwen also supported: "We carry out cell transformation, and the best experimental subject is also cloned.

In the field of human biological research, it is the best and irreplaceable experimental subject."

Zhou Yu was in a state of confusion. When he saw Chen Jin's eyes signaling, he immediately decided: "The clone is the company responsible. You can carry out the preliminary preparations for the experiment first, and the project funds will be allocated soon."
