I Have A Super USB Drive

For the next month, Chen Chen didn’t go anywhere, staying at the embassy every day to look up 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 limitation, Chen Chen almost absorbs all the biological knowledge currently known to mankind at the speed of swallowing the sea.

Unconsciously, the time has come to the federal government on January 31, 2022. If Chen Chen is still in school at this time, it will 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 oclock in the afternoon, Chen Chen, who was reviewing the paper on the positional effect of human gene activation based on CRISPRCas9system, suddenly had a feeling in the heart. He took out his mobile phone, and after a little hesitation, he dialed the very familiar one. phone.

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 are you free to call mom?”

On the other end of the phone, Chen Chens mothers voice came out, “Dont worry, your dad and Im fine here. After listening to your suggestion, your dad has bought a villa and its being renovated.”

“In the future, you dont have to move out to live in when you get married. I can help you hold your grandson…”

“But, your dad still has that problem. He is very generous to relatives… Forget it, I’ll get angry when I mention this!”

“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 be busy outside. You have to go home when you have time. By the way Bring a girlfriend back, huh?”

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

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

When I 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 lifespan escape plan…”

Chen Chen murmured, this plan is a plan Chen Chen began to envisage after getting the USB flash drive, aimed at forcibly removing The overall lifespan of the expert category, the ultimate plan to 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.

So, Chen Chen envisioned this plan for all mankind.

If you want immortality, you must first break the Heflick limit of the human body to obtain longevity. After you have the technology of longevity, 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 Chens embryo cloning project is different from the gene-edited baby incident that occurred in Zhongzhou in 19 years.

The gene-edited baby incident of that year was a medical madman who knocked out the genes that can be infected with HIV in his embryos and implanted the embryos into women within the body, without complying with laws and ethics. Cause her conception.

The specific use of that person is a gene editing technology called CRISPRCas9, which modifies the CCR5 gene of the baby during the embryonic period in an attempt to form a CCR5-32 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 acid. When attacking bacteria, it will embed itself in the bacterial nucleic acid chain like a parasite, and then secretly insert the bacterial nucleic acid Take it down and make it the same as yourself, to copy yourself.

So, in order to protect itself, bacteria have evolved this repetitive gene sequence called CRISPR, which is “cut” when the virus is embedded in the nucleic acid strand within the body.

And 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.

So, the famous CRISPRCas9 technology appeared.

And that person chose to modify the CCR5 gene because CCR5-32 formed after the mutation of CCR5 is a naturally occurring genetic mutation in 10% of Europeans within the body. After research, it carries this Mutated humans have the ability to resist HIV infection.

However, Chen Chen once checked the experimental data released by this person, but found that this persons technology is not in place, and it may even cause three different mutations in the embryo, and the effects of these mutations are all Is unknown.

To put it simply, it is very likely that it has already been missed when it is forced to hit the target…

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

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

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

No one can afford this Kind of risk.

even more how, this persons experiment did not have any technical breakthrough, and the CRISPRCas9 technology was not invented by him. All the technologies he exercised in the scientific community are a basic operation, a kind of any What a scientist can do.

In Chen Chen’s view, whether it is scientific design, technical implementation, or ethics, each step has done a mess!

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 CRISPRCas9 technology to modify the CCR5 gene of a human embryo, but the embryo is not at all born, then he is not breaking the law.

Unfortunately, for the sake of fame and fortune, this person has reached the point of madness…

The ethical aspect involved in Chen Chens plan is the technology of cloning human embryos, but simply The cloned embryo is not illegal in the international arena. After all, in the eyes of many scientists, the newly developed human embryo does not even produce the brain, but is just a mass of meat.

Just like the abortion technology, when the pregnancy is more than 14 weeks, it is generally not recommended in medical and ethical terms. Because 14 weeks is a critical point, the brain of the fetus after 14 weeks has begun to develop rapidly. From this time on, he was already considered a human.

As for whether human embryo cloning technology violates ethics or morality, this debate has always been a big problem in academia.

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

In simple terms, the development of medicine will always be a double-edged sword. Ethics and morality continue to involve technology. Without ethics and morality, medicine 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 to 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 kind of argument:

“The number of any kind of race is impossible too much, and rats breed too fast, so there are After the plague, the deer reproduced too fast and there were wolves. Nature will always balance them, except for humans.”

“So, nature is too kind to humans, we should take care Repay nature!”

And Chen Chen’s answer to these people is:

It’s not that nature is kind to mankind, but because mankind is constantly advancing and defeating nature…
