my black technology library

After half a year, the human genetic enhancement project has finally made progress.

Li Yi excitedly closed the video call with Professor Wei Hangzhi, and immediately rushed to the experimental center - the experimental area of ​​the gene project, to participate in their experiments.

In the control room of the genetic project experiment, Professor Wei Hanzhi, Lin Manyun, Wang Yangping, members of the scientific research team participating in the genetic enhancement project gathered together, and they anxiously waited for Li Yi to start the verification experiment.

Li Yi hurriedly walked into the experimental control room, and everyone greeted him enthusiastically.

"Mr. Li, you came just in time. The preparations for the experiment have been completed and are about to start." Professor Wei Hanzhi looked at Li Yi and introduced.

"Hmm! Are you sure?" Li Yi nodded and walked straight to the console.

In front of the console is a virtual projection area. After Li Yi walked in, he saw a biological laboratory in front of him. It was a biochemical laboratory located on the moon base. The genetic enhancement experiment project was a very dangerous biochemical experiment. The appearance of the biochemical series may not necessarily cause a 'resident evil'.

Therefore, the biochemical laboratory for researching the gene enhancement project was built separately near the moon base. The entire laboratory adopted advanced intelligent and mechanized technology, and was equipped with virtual network technology for remote linking, which was extremely safe.

Li Yi entered the projection area of ​​the virtual laboratory, and the picture in front of him changed, showing an advanced sci-fi laboratory filled with various biological instruments and extremely clean.

"Mr. Li, we have conquered the expression of all gene codes and the key code for turning off the expression of mitochondrial genes. In theory, we have mastered the key key of gene expression. This experiment will confirm the accuracy of the 'key' Sex." Professor Wei Hanzhi explained.
"By trying to synthesize and purify 7s&nt, and then found that 7s&ntdna, and thus unable to initiate mitochondrial gene expression." After a pause, Professor Wang Yangping continued to introduce.

"Mitochondrial gene expression is a process of dynamic balance. &ntexo can degrade 7s&nt to start expression on dna, generate 7s&nt to form dimers, and inhibit its activity, while mtexo can degrade 7s&nt to restore activity..." Professor Lin Manyun looked at Li Yi, excited added at last.

All the scientific experts at the scene were very excited. After so long of scientific research, they finally found a way to control the fusion adaptive gene and reduce its negative alienation to humans.

Li Yi nodded, understanding their feelings very well, and announced with a smile: "If there is no problem, let's start the experiment!"

Hearing this, all scientific research experts looked at Professor Wei Hanzhi one after another.

Professor Wei Hanzhi looked at the intelligent experiment assistant in the virtual laboratory impatiently, and ordered: "Xiaoyue, start the first gene fusion experiment immediately."

"Okay! Professor Wei." The intelligent experiment assistant - Xiaoyue responded. Immediately, a gene compilation instrument in the virtual experiment center started to start.

Inside the instrument, the tiny nano-scissors operate by themselves, cutting the ends of the experimentally cultivated genes, and then merging them with other short genes, and then injecting them into a certain cell for cell cultivation.

At the scene, Li Yi and a group of scientific research experts watched the progress of the experiment intently.

"Mr. Li, the first stage of the experiment is completed by embedding the adaptive gene, and the next step is to optimize the gene." Professor Wei Hanzhi looked at Li Yi and introduced.

"Oh! What is the optimization for the second stage of the experiment?" Li Yi asked with concern.

"We use T cells and NK cells as two different cell chassis to construct an engineered cell library that recognizes more than 106 potential antigens in diversity. Next, we plan to optimize the immune system of cancer cells." Professor Wei Hanzhi smiled introduce.

"That's right, now that the controller is injected into the gene circuit..., when the immune cells are activated to recognize tumor tissue antigens, the corresponding effector immune cell clones will begin to expand and enrich. After the effector immune cells reach a certain scale, they can To remove tumor cells expressing these antigens, the ability of synthetic immune cell repertoire to recognize antigens is persistent. When tumor tissue undergoes biological evolution due to the killing effect of immune cells, synthetic immune cell repertoire can correspondingly produce brand new effector clones ,..." Professor Wang Pingyang added to Li Yi with a smile.

Li Yi nodded, and probably understood: "Are you planning to make human beings immune to cancer through this enhanced genetic experiment?"

"Yes, but cancer genes will also evolve. Considering that large-capacity repertoires may identify healthy genes and cause other side effects, the range of antigen information that can be recognized by synthetic immune cell repertoires is determined during the preparation of repertoires. Despite the limitations and presuppositions, the current experiment shows that the synthetic immune cell repertoire can effectively play an immunotherapy role in tumor models including colon cancer, lung cancer, breast cancer and ovarian cancer." Professor Wei Hanzhi introduced.

"That's right, experiment step by step, don't try to eat fat people in one step." Li Yi nodded in agreement.

While talking, the second phase of the biochemical experiment started. Under the control of the intelligent experiment assistant Xiaoyue, the experiment has been carried out according to the experimental steps preset by Professor Wei and the others.

The scientists, as well as Li Yi, watched the experiment while conducting academic discussions.

As a semi-professional, Li Yi can only listen and applaud from the sidelines.

However, Professor Wei and the others were in high spirits, and Li Yi couldn't help being happy with the joyful discussion atmosphere.

Li Yi communicated with Dahei in private, and the experiment went well. This human gene enhancement project will start producing scientific research results within a month.

At that time, the genetically enhanced human beings will not only be able to adapt to the vacuum environment of the universe, but may also be immune to diseases such as cancer, and perhaps their lifespan and physical strength will also be greatly improved.

……

Time flies, and the night passes.

The morning sun slanted in through the window.

On the luxurious big bed, Li Yi blinked, stretched comfortably, and turned over to get up.

Outside the floor-to-ceiling windows, the bright sun shines on the lawn, flowers, and leaves in the garden. Father-Li Yanshou takes the twins, playing with balls in the garden, and the big black lying on the floor is surrounded by his "great-grandson" little black The dog clings and writhes on it.

Li Yi smiled. When he woke up every morning, seeing such a lively scene, he felt really happy from the bottom of his heart.

Li Yi quickly went into the bathroom, washed up, changed into a set of casual clothes, and went straight downstairs.

In the restaurant, Zhou Wenhui was arranging the plates, ham sandwiches, hot milk, fried eggs, roast beef,...all kinds of delicacies filled the table.

"Yi, get up, you go and call Dad and the others in for breakfast, and I'll call Xiaoyang, Xiaoqing." Zhou Wenhui saw Li Yi, glanced at the garden, and arranged.

"Okay!" Li Yi nodded and walked straight to the garden.

Zhou Wenhui turned around and walked towards the room of the eldest son - Li Yang, and the second daughter - Li Qing.

After a few minutes, the restaurant became extremely lively, and everyone sat at the dining table and enjoyed the food.

"Mummy, I want to eat beef!" Li Yan looked at Zhou Wenhui and begged.

"You've already eaten a piece, finish the food first, and then we'll talk." Zhou Wenhui refused.

"Mom, let my sister eat this piece of meat!" Li Qing picked up the steak on the plate with chopsticks, and was about to put it on Li Yan's plate.

"No, you don't eat meat every day, you're not as heavy as your sister, so eat it quickly." Zhou Wenhui put the steak back on Li Qing's plate.

Li Qing pouted, looking at the steak on the plate with a helpless expression on his face.

In order to eat a piece of steak, Li Yan stuffed a small piece of broccoli and a carrot into her mouth with her small hands, worked hard in twos and twos, and ate up all the vegetables on the plate.

"Mum, the dishes are finished, I want to eat beef." Li Yan pointed to the empty plate, looked at Zhou Wenhui and signaled.

"Can you still eat it? If you continue to eat, sooner or later you will become a chubby girl." Zhou Wenhui angrily picked up a small piece of beef and put it on Li Yan's plate.

Looking at Li Qing, who was struggling to eat the steak, so thin and with no flesh on his cheeks, Zhou Wenhui couldn't help feeling dizzy.

They were both born to the same parents, so I don't understand why there is such a big difference between the two sisters, Li Yang and Li Rong are the same, the elder brother has a good appetite, but the younger brother is a skinny monkey with limited appetite.

Seeing Zhou Wenhui's distress, Li Yi smiled and said, "Let her eat! Even if she becomes a chubby girl due to overnutrition, after the development of the genetic enhancement medicine is completed, there will be a way for her to lose weight."

Hearing this, the family members looked at Li Yi curiously.

"Dad! What is a genetic enhancement project! Can it turn us into superhumans?" Li Yang looked at Li Yi curiously, and asked the question that everyone cared about.

"Superman is definitely not enough, but it can be done by optimizing the genes and strengthening the body's resistance to harsh environments." Li Yi explained with a smile.

"Oh! Can it help you lose weight? Can it also improve your appetite?" Zhou Wenhui's eyes lit up, she looked at Li Yi and asked with concern.

Zhou Wenhui is 41 years old. Although she has been injected with the life-prolonging gene, she is still young at this age, and she usually pays attention to fitness and maintenance. However, after giving birth to four children, she will inevitably become more charming, and she will never return to her youthful days stature.

Therefore, Zhou Wenhui paid special attention to whether the gene enhancement drug developed by Li Yi could be used for weight loss.

"Losing weight, it should be possible! However, this gene enhancement agent is researched for human beings to adapt to the vacuum environment of the universe. At the same time, it has the function of making human beings immune to cancer and optimizing many defective genes in the human body. Obesity can be regarded as a disease." It must be a huge physical defect!" Li Yi explained with a smile.

Listening to the conversation between her parents, Li Yan saw that the beef on the plate suddenly tasted bad.

"Daddy! What is obesity! Will Xiaoyan become a fat man in the future?" Li Yan looked up at Li Yi and asked worriedly.

"Hahaha, no, Daddy won't make you fat, so don't worry about eating meat!" Li Yi laughed and comforted him.

"Yeah! Daddy is the best!" Li Yan continued to eat meat happily.

"Yi, when will this genetic enhancement drug be developed? Can it really be used for weight loss?" Zhou Wenhui asked with concern.

"In a few months! I'll tell you as soon as the results come out." Li Yi said with a smile.

"Dad! Can you tell me about obesity? Why do some people get fat and others don't!" Li Yang asked Li Yan, Li Qing looked back and forth, and asked Li Yi for advice.

Li Yi nodded and introduced with a smile: "All the characteristics of the human body are controlled by the genes in the body, so the signs of obesity are also controlled by an obesity gene. Maintain a stable balance between energy, so that even if you eat a lot of food, the "obesity gene" will still control your weight, and even if you eat more, it is not easy to gain weight."

"On the contrary, when the "obesity gene" is out of balance, it will lead to a large amount of fat accumulation, and the body's weight will increase rapidly, and gradually become a big fat person. This "obesity gene" is not an exclusive gene for modern humans, but It is accompanied by the evolutionary history of ancient humans and passed down from generation to generation."

"In the long time, the ancient human beings had very little time to eat enough. Most of the time, they had to endure the threat of hunger. Due to the frequent "famine", the human beings at that time needed to eat when there was enough food. , Let yourself be full, and then make yourself "fat" as much as possible, and hoard a little more fat."

"During this process, the "obesity gene" in the human body mutated. When ancient humans obtained high-calorie food, it would help them accumulate fat. Although ancient humans evolved from generation to generation, after humans entered the stage of civilization , It is no longer necessary to rely on this method to store fat, but the mutated "obesity gene" still remains."

Li Yi eloquently popularized knowledge about obesity to his children.

Li Yang's eyes were bright, he understood what Li Yi introduced, and Li Qing seemed to understand something.

"Now, our human science and technology are highly developed, agriculture and animal husbandry are moving towards unmanned mechanical production, various material resources are highly developed, and food is abundant. In our country, no one is hungry now, but what, our body This 'obesity gene' still exists, so some people who don't know how to get food in moderation will become fatter and fatter, which is why there are more and more fat people." Li Yi finally concluded.

"So it's like this, Xiaoyan, eat less, or I won't be able to hold you when I become a chubby little sister." Li Yang suddenly understood, looked at Li Yan who was eating steak, and reminded.

"You are talking nonsense, Daddy will not let Xiaoyan become a chubby girl." Li Yan glared at Li Yang angrily, unwilling to put down the beef.

Li Yang chuckled and wanted to say something, but Li Yi suddenly interrupted: "Hurry up and eat! It's almost time for school, don't be late."

After hearing Li Yi's words, the fourth child stopped making noise immediately and concentrated on eating.
