I Have A Super USB Drive

For the next month, Chen Chen didn't go anywhere, and stayed at the embassy every day to read 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 moving forward step by step.

When the access to knowledge is no longer a limitation, Chen Chen has absorbed all the biological knowledge currently known to mankind at the speed of swallowing the sea.

Unconsciously, the time came to the Federation on January 31, 2022. If Chen Chen was still in school at this time, the time happened to be the end of the first half of the sophomore year.

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 reviewing the paper on "Location Effect of Human Gene Activation Based on CRISPR/Cas9 System", suddenly felt something.

Namibia is in the East Zone 1 time zone, which is six hours apart from the Central Continent District. At this time, the time in the Central Continent District is exactly eight o'clock in the evening.

"Hey, Xiaochen, why are you free to call Mom?"

On the other end of the phone, Chen Chen's mother's voice came out, "Don't worry, your dad and I are fine here. After listening to your suggestion, your dad has already bought a villa and is currently renovating it."

"In the future, when you marry a daughter-in-law, you don't have to move out. Mom can help you hold your grandson..."

"However, your dad still has the same problem. He is poor and generous to his relatives... Forget it, I get angry when I mention this!"

"By the way, Xiaochen, when are you coming back? I haven't seen you for a whole year since the Chinese New Year last year. Don't be too busy outside, go home and have a look when you have time, and bring a girlfriend by the way. come back, eh?"

Listening to his mother's ramble, Chen Chen agreed like a worm, and it took half an hour to hang up the phone.

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

When he opened it again, that smile was completely hidden in the dark pupils.

The farther away he is from home, the more he misses the beauty of home, but because of this, Chen Chen wants to keep this beauty forever.

"The Human Lifespan Escape Plan..."

Chen Chen murmured in a low voice that this plan was the plan that Chen Chen began to conceive after he obtained the USB flash drive. It was the ultimate plan to forcibly increase the overall lifespan of human beings and do his best.

The root of this plan was to serve Chen Chen's parents. After all, Chen Chen didn't want to live alone for a long time, and he hoped that his relatives could accompany him all the time.

Of course, the same is true for parents. They also have the most concerned relatives of their generation, and they definitely hope that they can accompany them.

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

If you want immortality, you must first break the Hayflick limit of the human body to obtain immortality. After you have the technology of immortality, you are 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 project was different from the gene-edited baby incident that happened in Zhongzhou in 2019.

In the case of the gene-edited baby that year, a medical madman knocked out the gene that can infect the HIV virus in the embryo and implanted the embryo into a woman, causing her to conceive.

And what that person specifically uses is a gene editing technology called CRISPR/Cas9, which modifies the CCR5 gene in the embryo in an attempt to form the CCR5-Δ32 mutation.

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

In simple terms, a virus is like a robot mainly composed of nucleic acids.

When attacking bacteria, it embeds itself into the nucleic acid chain of bacteria like a parasite, and then secretly removes the nucleic acid of bacteria to make the same appearance as itself to replicate itself.

So, in order to protect themselves, bacteria have evolved this repetitive gene sequence called CRISPR, and when the virus is embedded in the nucleic acid chain in its own body, it "cuts" it down.

Cas9, on the other hand, is the name of a protein nuclease that CRISPR uses to bind two RNAs to cut double-stranded DNA, either cutting or making other changes.

Thus, the famous CRISPR/Cas9 technology appeared.

And that person chose to modify the CCR5 gene because CCR5-Δ32 formed after CCR5 mutation is a genetic mutation that occurs naturally 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 was even possible to cause three different mutations in the embryo, and the effects of these mutations were unknown.

To put it simply, it is very likely that this force has missed the target when shooting...

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

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

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

No one can afford this risk.

What's more, this person's experiments did not have any technical breakthroughs, and CRISPR/Cas9 technology was not invented by him. All the technologies he has exercised are basic operations in the scientific community, and it is a kind of operation that any scientist can do. to things.

From Chen Chen's point of view, whether this person is scientific design, technical implementation, or ethics, he has done a mess at every step!

It is also normal for this person to be sentenced to prison. The Central Continent District has promulgated a corresponding law in 2003, which strictly prohibits any human embryo gene editing activities for the purpose of reproduction.

That is to say, if the person just 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.

It's a pity that this person has reached the point of madness for the sake of 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 only Just a lump of meat.

Just like the abortion technology, abortion is generally not recommended medically and ethically when the pregnancy is more than 14 weeks, because 14 weeks is a critical point, and the brain of the fetus after 14 weeks has begun to develop rapidly. a human.

As for whether human embryo cloning technology violates ethics or not, this debate has always been a major problem in the academic world.

In fact, Chen Chen also knew that this was a minor violation, but in his opinion, if this kind of minor violation can be exchanged for medical progress, more diseases can be cured, and more people can be freed from suffering, the price is still worth it. of.

To put it simply, the development of medicine is always a double-edged sword. Ethics and morality are constantly involved in technology. Medicine without ethics and morality can only fall into the abyss of destruction step by step.

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

However, Chen Chen always believed in one sentence, that obstacles to development will not stop development. The progress of human science and technology is always accompanied by obstacles. Many people know that human beings must protect the earth and the natural environment.

But they have forgotten that the motivation of human beings to protect the earth's environment is because human beings need to protect themselves. If the earth's environment is destroyed, human beings will cease to exist.

This is the real motivation of human beings to protect the earth.

Of course, some grateful conservationists often make this argument:

"The number of any species cannot be too large. Rats reproduce too fast, so there is the plague. The deer breed too fast and there are wolves. Nature will always balance them, with the exception of humans."

"So, nature is too kind to human beings, and we should repay nature well!"

And Chen Chen's answer to these people is:

Not because nature is kind to human beings, but because human beings are constantly advancing and conquering nature...
