I Have A Super USB Drive

For the next month, Chen Chen didn't go anywhere and stayed at the embassy every day to look up the theories and papers related to biology.

From induced pluripotent stem cells to regenerative medicine, from biomaterials to tissue engineering, from genetic engineering to cell engineering, Chen Chen is advancing step by step.

When the access to knowledge is no longer a restriction, Chen Chen is almost absorbing all the biological knowledge currently known to mankind at the speed of swallowing the sea.

Unconsciously, the time came to the federal government on January 31, 2022. If Chen Chen was still in school at this time, it would happen to be the end of the first half of the sophomore semester.

At the same time, this day is also the most important traditional festival in Zhongzhou District-New Year's Eve.

At two o'clock in the afternoon, Chen Chen, who was reading the paper on the "location effect of human gene activation based on the CRISPR/Cas9 system", suddenly felt something. He took out his mobile phone, and after a little hesitation, he dialed the very familiar call.

Namibia is the first time zone in the East, which is six hours away from the Central Continent. At this time, the time in the Central Continent is exactly eight o'clock in the evening.

"Hey, Xiaochen, why did you call mom when you were free?"

On the other side of the phone, Chen Chen’s mother’s voice came out, “Don’t worry, your dad and I are good here. After listening to your suggestions, your dad has bought a villa and it is under renovation.”

"In the future, when you marry a wife, you don't have to move out to live. Mom can help you hold your grandson..."

"But, your dad still has that problem, he is generous to relatives... forget it, I get angry when I mention it!"

"By the way, I said Xiaochen, when will you come back? I haven't seen you for a whole year since the Chinese New Year last year. Don't just be busy outside. You have to go home when you have time and take a girlfriend. Come back, huh?"

Listening to the mumbling of his mother, Chen Chen answered like a worm, and it took a full half an hour to hang up.

After hanging up the phone, Chen Chen closed his eyes slightly with a residual smile in his eyes.

When he opened it again, the smile disappeared in the dark pupils.

The farther away you are from home, the more you miss the beauty of home, but because of this, Chen Chen wants to keep this beauty forever.

"Human Life Escape Plan..."

Chen Chen murmured in a low voice, this plan is the plan Chen Chen began to envision after getting the U disk. It aims to forcibly increase the overall life span of human beings and do everything possible.

The bottom line of this plan is to serve Chen Chen's parents. After all, Chen Chen does not want to live alone for a long time. He hopes that his relatives can always accompany him.

Of course, the same is true of parents' thinking. They also have their own generation's most concerned relatives, and they certainly hope that they can be with them.

As a result, the plan that Chen Chen envisioned for all mankind appeared.

If you want immortality, you must first break the limit of the human body to obtain longevity, and only after possessing the technology of longevity can you be qualified to pursue that illusory immortality.

It can be said that everything Chen Chen has done so far is paving the way for this plan.

Of course, Chen Chen's embryo cloning plan is still different from the gene-edited baby incident in Zhongzhou District in 19 years.

In the gene-edited baby incident that year, a medical madman knocked out the genes that can be infected with HIV in his embryos, and implanted the embryos into a woman's body, causing him to become pregnant.

And that person specifically used a gene editing technology called CRISPR/Cas9, which modifies the CCR5 gene of the baby during the embryonic period in an attempt to form a CCR5-Δ32 mutation.

The so-called CRISPR is actually an immune system produced by bacteria to defend against virus attacks.

Simply put, a virus is like a robot mainly composed of nucleic acid.

Therefore, in order to protect itself, bacteria have evolved this repetitive gene sequence called CRISPR, which is "cut" when the virus is inserted into the nucleic acid chain in its body.

Cas9 is the name of a protein nuclease. CRISPR can cut double-stranded DNA by combining two RNAs with this nuclease, which can cut and make other changes.

Thus, the famous CRISPR/Cas9 technology appeared.

And that person chose to modify the CCR5 gene because CCR5-Δ32 formed after the mutation of CCR5 is a naturally occurring genetic mutation in 10% of Europeans. After research, humans with this mutation are resistant to HIV infection. ability.

However, Chen Chen had checked the experimental data released by this person, but found that this person's technology was not in place, and it might even cause three different mutations in the embryo, and the effects of these mutations are unknown.

To put it simply, this is actually very likely to have been missed when shooting...

Moreover, the potential impact of missing CCR5 gene is far beyond human cognition.

The reason why the entire scientific community has reprimanded this matter is that this modified gene will be integrated into the human gene pool, which means that after the two gene-edited babies give birth to offspring, their children and grandchildren will also Will carry this gene.

Thousands of years later, if the hidden danger of this gene suddenly bursts out, the impact at that time is likely to involve the entire human race...

No one can afford this risk.

What's more, this man’s experiment did not have any technological breakthroughs, nor did he invent the CRISPR/Cas9 technology. All the technologies he exercised are a basic operation in the scientific world, and it is a kind that any scientist can do. To the thing.

In Chen Chen's view, whether it is scientific design, technical implementation, or ethics, this person has done a mess at every step!

It is normal for this person to be sentenced to imprisonment. Zhongzhou District has promulgated corresponding laws as early as 2003, prohibiting any human embryo gene editing activities for the purpose of reproduction.

In other words, if the person only uses CRISPR/Cas9 technology to modify the CCR5 gene of a human embryo, but the embryo is not born, then he is not breaking the law.

Unfortunately, this person has reached the point of being frantic for fame and fortune...

The ethical aspect involved in Chen Chen’s plan is the technology of cloning human embryos. However, simply cloning embryos is not illegal in the world. After all, in the eyes of many scientists, the newly developed human embryos do not even produce brains, but It's just a mass of meat.

Just like the abortion technology, it is generally not recommended in medical and ethical terms for abortion when pregnant for more than 14 weeks, because 14 weeks is a critical point, and the brain of the fetus over 14 weeks has begun to develop rapidly. From this time on, he has been regarded as A human being.

As to whether human embryo cloning technology violates ethics, this debate has always been a big problem in the academic community.

In fact, Chen Chen also knows that this is a small violation, but in his opinion, if such a small violation can be exchanged for medical progress, it can cure more diseases and keep more people away from pain. This is worth the price. of.

To put it simply, the development of medicine is always a double-edged sword. Ethics and morality continue to involve technology, and medicine without ethics and morality can only fall into the abyss of destruction step by step.

However, if the bottom line of ethics and morals is set too high, it will also hinder technological progress.

However, Chen Chen always firmly believes that the obstacles of development will not prevent development. The progress of human science and technology is always accompanied by obstacles. Many people know that humans must protect the earth and the natural environment.

But they have forgotten that the motivation of mankind to protect the earth's environment is that mankind needs to protect itself. If the earth's environment is destroyed, mankind will no longer exist.

This is the real motivation for mankind to protect the earth.

Of course, some grateful nature conservationists often make this argument:

"There cannot be too many of any kind of race. Rats reproduce too fast, so there is the plague, the deer reproduce too fast and there are wolves. Nature will always balance them, except for humans."

"So nature is so kind to humans, we should repay nature!"

And Chen Chen's answer to these people is:

It is not that nature is kind to humans, but because humans are constantly advancing and defeating nature...
