Regarding the jump gene editing tool technology, Xu Mang has been authorized to the Institute of Biochemistry and Cell Biology of the Academy of Sciences, for the future gene editing field, Xu Mang does not want to enter it again, he has finished the road of biological science, what the future will look like, this is not what he can portray.

All Xu Mang can do is to provide technology to the world, and where this technology will be used in the end, Xu Mang will not ask anything, to be precise... The technology is there, he just went over and moved it over, that's all.

But...

Because of gene editing tool technology, Xu Mang was involved in a storm again, many so-called popular science programs, and even some celebrities began to openly oppose gene editing technology, the reasons are still those reasons, there is no freshness.

On this day,

Xu Mang received a phone call, it was from the director of a well-known program, hoping that he could go on the show and have a live debate with some people who oppose gene editing, for this nonsensical request, Xu Mang hung up the phone directly, and asked Xiao Man to check the details of the other party, this guy is either an idiot or mentally retarded.

"This Nima... Let me be on the show and debate with others... I don't have that much time. Xu Mang sat in the office, his words were full of anger towards the director, but Xiao Man, who was even more angry, called and told him that the other party had some strength, and it seemed to be a nephew of a certain person.

"Husband... Actually, it's not a big deal. Yang Xiaoman said nonchalantly: "Compared with the uncle, it's a few grades worse, or... I'll talk to my uncle and ask him to take care of that director? I'll tell you... This kind of person only needs to find out if something happens. ”

"Forget it..."Xu Mang said helplessly: "This matter... It's related to the previous thing, in case it is involved, I'm afraid it will affect the development of this field, and there is no way... Things are too big, after all, the good side hides the darkness of the other side. ”

Yang Xiaoman knew what Xu Mang was talking about, that is, a professor learned that gene editing technology could obtain commercial benefits, and immediately used CRISPR-Cas9 technology to immunize the CCR5 gene with an institution under the premise of violating scientific ethics.

There were many violations of the regulations, which directly led to a series of tragedies.

So far...

There was a lot of uproar, and Xu Mang was also implicated, although he was just a firefighter, but there was no way... This fire is too big, but Xu Mang's attitude is the same as others, and this kind of thing should not be done when the technology is not yet clear.

Pity... It's too late.

"Ugh..."

"So be it, I'm going to a meeting. Yang Xiaoman paused and said with a squeak: "Husband... I think..."

"No!"

"You don't want to!" Xu Mang reprimanded harshly: "Work hard!"

Syllable!

Xu Mang hung up the phone directly, although he didn't know what Xiao Man wanted to do, but there must be nothing good, there was no need to think about it at all, if there was a good thing, he would have said it directly, and he still needed this squeaky tone.

moment

The furious Xiao Man dialed Xu Mang's phone again.

"Bastard!"

"How dare you hang up my phone?" Yang Xiaoman said angrily: "The day after tomorrow, I will go to school and get my degree certificate, you will accompany me, by the way... In the evening I invited my classmates to the bar with me, and you must also show me to the old lady. ”

"Oh..."

"I have something to do now..."Xu Mang said helplessly: "Hang up..."

After getting a little time to be quiet, Xu Mang took a long breath and picked up the quantum material plan at hand again, which was originally going to be solved yesterday, who knows... I fell asleep on my own and could only stay until today to solve the problem.

"Yao Shui?"

"You and all the members of your group should come to my office and bring the latest research materials with you. Xu Mang made a phone call to Sun Chuanxiao's eldest nephew, Sun Yaoshui, who needed to check the progress of the quantum materials group.

When he hung up the phone, Xu Mang reacted, sometimes people are like this, living and living have become what they once hated the most, and they used to hate those who worked hard, or those who forced you to work hard.

In the past, Xu Mang recognized himself very early, recognized that he was a waste material, and thought from another angle, which was a kind of relief... In this unfair world, the speed at which a person works sometimes simply cannot keep up with the rate at which prices per square meter rise.

I didn't have any worries in high school, and I got by... At that time, the days were happy race fairies, and I originally thought that this kind of life could continue forever, after all, if people don't have dreams, it is equivalent to being carefree, but... I still can't forget those dreams.

soon

The six members came to Xu Mang's office, and Sun Yaoshui stood at the front with a stack of materials, looking a little nervous.

"Don't be nervous. ”

"I'm not here to educate you, but to see your progress. Xu Mang smiled and said, "I'm not the kind of annoying annoying spirit. ”

But...

The few people present almost didn't believe Xu Mang's words, reasonable... Everyone has come from the era of reading, who hasn't been deceived by such a bridge?

When Xu Mang got the research materials, he flipped through them a little, and his expression was slightly embarrassed. It's just that there's no progress, and there's a lot of research, and the results are of no use at all.

"Wrong direction..."

"First of all, we need to investigate why magnetic topological insulators have not been experimentally obtained. Xu Mang said indifferently: "If there is no breakthrough in theory, then there will be no great progress at all, and in theory, you are a graduate student in the Department of Physics of Fudan University, so you should be a strong point, right?"

“...”

“...”

“...”

None of the five graduate students from the Department of Physics of Fufu University spoke or stood quietly in front of Xu Mang, pulling their heads.

"First of all, an ideal magnetic topological insulator should be intrinsic, that is, it has a definite stoichiometric ratio, the magnetic elements are arranged in an orderly manner, the topological insulator above the Curie temperature is the topological insulator, and the Curie temperature is below the long-range ferromagnetic sequence. ”

"We're going to go in this direction and dig deeper into the potential in topological insulators. Xu Mang said seriously: "I would like to provide an idea here, the quantum anomalous Hall effect, a kind of quantum Hall effect that can occur without an external magnetic field. ”

Quantum anomalous Hall effect?

Then

It occurred to several of you that the quantum anomalous Hall effect was achieved for the first time by doping magnetic elements into topological insulators to introduce magnetic ordering, but it is not an ideal method to introduce magnetic ordering into topological insulators by magnetic doping.

Magnetic doping brings a high degree of disorder and electrical and magnetic inhomogeneity to the material, which leads to extremely low quantum anomalous Hall effect realization temperatures, and also seriously interferes with chiral Majorana fermions.

"Professor Xu?"

"Are you asking us to find magnetic topological insulators in the same way?" asked one graduate student.

"Uh..."

"It's up to you to do it. Xu Mang shrugged his shoulders and said with a smile: "In short, first pass the theoretical proof, and then carry out the relevant preparations, the theoretical proof of this project is related to whether you can graduate from graduate school." ”

“？？？”

“？？？”

“？？？”

What the?

This... Isn't that the end of it?

Hearing Xu Mang's words, the five people present couldn't help but gasp, how difficult is the theoretical proof of magnetic topological insulators, the whole world is looking for theoretical exploration, and there has been no breakthrough until now, but the problem of this century has fallen on him.

That's basically cold, and I don't want to get my graduation certificate.

"What's wrong?"

"It's not a big deal, is it?" said Xu Mang with a smile: "That's... I'll solve the theoretical framework, you will implement my theory, and then tap into the potential of magnetic topological insulators, and dig as deep as possible!"

This is acceptable,

If Professor Xu Mang solves the theory, and he uses Professor Xu Mang's theory for experiments, there should be no problem.

Several people agreed to the plan and left the office.

At this point,

The main reason is that this ideal is too ambitious, and it should be intrinsic, that is, it has a definite stoichiometric ratio, and the magnetic elements are arranged in an orderly manner, and above the Curie point is an ordinary topological insulator, and below it has a magnetic topological insulator with a long-range ferromagnetic sequence.

"Ugh..."

"It would be nice if you could use the material database!" Xu Mang collapsed in his seat, annoyed by the problem he was facing, this damn topology... It makes no sense to make my database and quantum material database, but I don't have the ability to develop a topological material database, and I can't meet the requirements in terms of technology or theory.

"Forget it..."

"Let's go home first!" Xu Mang stretched, cleaned up the things on the table, and then left the Xu Yang Research Institute.

...

Following

Located in the Key Laboratory of Nuclear Physics and Technology,

In an hour or two, there will be a press conference to report on Gyro-2, and of course Academician Zhou's real purpose is to show the world the achievements of China in thermonuclear fusion experiments.

"Old Zhou?"

"The scale is a bit big this time!" Liang Feng found Academician Zhou and said with a smile: "Not only our domestic attention is very concerned, but even the Western media have also come, did you inform you?"

"Hmm!"

"Let me publicize the comrade help to inform you. Academician Zhou said indifferently: "To prove to the world that in the field of thermonuclear fusion reactions, our country is at the forefront, and at the same time strengthen the public's awareness of us." ”

"Ugh..."

"Honestly... Professor Xu, no... It's Academician Xu who is too strong. Liang Feng smiled bitterly: "How did he cross two fields and achieve such proud results in biology and physics? ”

"Who knows. ”

"But he just did it, and now his positioning is very embarrassing, physics, materials, biology, astronomy, etc., he is an authoritative figure, what kind of academician is it, there is no conclusion so far, but there is a strong demand from the Institute of Physics to generalize to physics. Academician Zhou said.

“...”

"This is the first time I've encountered such a situation. Liang Feng smiled.

Long

The No. 2 press conference began, and Academician Zhou, Liang Feng and two project engineers sat in front of the stage to answer questions from reporters and friends, but they were all painless questions.

At this time,

A foreign friend asked Academician Zhou seriously: "How to solve the problem of neutron scattering in thermonuclear fusion, this problem... The countries of Europe and the United States have not solved the problem, has China solved this problem?"
