In addition to the huge harm, the spread of pine wood nematode is even more unpreventable, which can be called AIDS among pine trees.

For example, the first batch of pine wood nematodes entering China turned out to be a factory that did not destroy the wooden frame of the outer packaging in time when introducing equipment, so that this pest could spread.

For a long time, people have not found any effective way to control pine wood nematodes. Many scientists rack their brains, but in the end, they also return to nothing.

Chen Zheyu interspersed a few things about his time when he was studying: "...... At that time, I also did some experiments in the hope of finding a way to contain pine wood nematodes, but in the end, nothing came of it. ”

"Later, my research direction gradually focused on microorganisms, and the pine wood nematode did not pay much attention. I'm a little curious, how do you get rid of those pine wood nematodes?"

Lin Han smiled slightly: "Actually, it's not a big deal, we just destroyed the reproductive ability of the pine wood nematode population." ”

Ordinary cleaning methods are obviously difficult to play a prominent role in this micron-sized insect with strong reproductive ability.

However, the strength of the pine wood nematode depends entirely on its super reproductive ability, and if it loses its reproductive ability, its individual life span is only a few months, and it will soon die.

The pine wood nematode that other scientific research institutions are completely helpless to solve, for Lin Han, it is difficult to solve with a wave of his hand.

It's just that his sentence "it's not a big deal" almost scared Professor Chen out of his seat.

Precise destruction of the reproductive capacity of all pine wood nematodes, and visual inspection of other invasive animals......

Such a black technology, if announced, is definitely enough to shake the academic community, a milestone achievement in the field of biological research.

This level of technology, when it came to Lin Han's mouth, became "no big deal"......

Chen Zheyu seemed to be frightened, and it took a while to calm down, and he sorted out his words and said, "With all due respect, Mr. Lin...... How much do you really know about biotechnology?"

Lin Han immediately reacted, and said with a smile: "It's really funny, my understanding of biology is basically at the high school level." As for some professional things in the company's laboratory, I don't know anything. ”

Professor Chen nodded, as if he was slightly relieved, but he was silent, his hands in front of him, his brows furrowed as if he was deep in thought.

The report meeting had already begun, and Director Wei was standing in front of the podium on the stage at this time, talking eloquently in front of the projection screen.

“…… Adhere to the party's leadership...... In order to implement the instructions of the central government on health work......"

Everyone in the audience was either sitting expressionless, or bowing their heads and playing with their mobile phones, and some students were reading and studying, anyway, basically no one paid attention to the content of Director Wei's speech.

And Director Wei himself seems to have long been used to it, and he looks calm throughout the whole article.

When he finished speaking, there was a round of warm applause from the audience, and then, as a representative of the Institute of Microbiology of Peking University, Chen Zheyu walked to the podium, patted the microphone and began to speak.

Since the seminar was held at the university, it can also be regarded as an academic conference to a large extent.

As the youngest Changjiang Scholar in China and an authoritative expert in the field of microbiology, Professor Chen Zheyu's lectures are also biased towards academics and full of dry goods.

“…… Wolbachia is a gram-negative intracellular symbiotic bacterium that can be transmitted through eggs, and its evolutionary history is very short, perhaps even less than 100 million years. But it can spread in a brutal way, and it is widely present in arthropods in nature......"

Many researchers and students in the audience listened attentively, sometimes whispering and talking.

Some students, in particular, are saying things like "Professor Chen looks so young".

Chen Zheyu pointed to the projection screen: "In the process of developing a new type of Wolbachia, our research has encountered some bottlenecks. ”

"Luckily, we got the help of Vientiane Laboratory, and after getting in touch with Mr. Lin Han, just a few days later, the institute received 1,500 Wolbachia variant ...... from Vientiane"

There was a sudden gasp from the audience.

1,500 variants in a few days!

"Cultivating mutants is so fast, no wonder Vientiane has so many black technologies. ”

"It's just a scientific research plug-in!"

"Alas, if only I could go to Vientiane Lab after graduation......"

Chen Zheyu spoke eloquently, and finally ended his speech with warm applause.

Then the representative of the CUHK research team, a professor surnamed Xi, went up to speak again, and the same academic content was discussed.

After Professor Xi finished speaking, Lin Han went up as a representative of the Vientiane Laboratory.

As soon as Lin Han went up, the audience raised their heads one after another, whether they were playing with their mobile phones, immersed in the joy of learning, or sleeping, they all moved their eyes to the young man on the stage.

"This is Lin Han himself?"

"You're really coming to our school......"

A master's student lifted his black-rimmed glasses and blinked: "I'll go, the big guy looks younger than me!"

"You're in too much of a hurry......"

Speaking of which, Lin Han really has a bit of a talent for speech. Regardless of whether you are nervous offstage or not, once you get on the stage and look down on everyone, you suddenly have a sense of self-confidence like a god possessing your body.

He smiled slightly and began to say, "When I was in the audience just now, I had a biological discussion with Professor Chen Zheyu. ”

The audience immediately began to discuss, and they all speculated about Lin Han's academic level of biology.

Lin Han paused and continued: "But after talking a few words, I suddenly realized that my major in college was not biology, but computer. ”

There was a burst of laughter mixed with applause from the audience.

“…… As we all know, finance and computer science are the two majors with the highest average salary at present, and they are also the easiest channels for people from ordinary backgrounds to achieve promotion. ”

"In contrast, a theoretical science like biology is somewhat impoverished by idealism. ”

"At a time when many biology students want to switch to computer science, I, as a computer science student, ran a company that specializes in biotechnology a few years after graduation...... That's pretty much a rarity. ”

As Lin Han talked eloquently, the group of biological researchers and students sitting below became a little silent.

As I said, in today's China, compared with engineering, the research of theoretical science is not very important, and was even called a "giant pit" for a time.

However, in the long run, the research of these basic sciences is indispensable for the scientific cause of the country and even for all mankind, and can be said to be the cornerstone of the entire human civilization.

Unfortunately, due to the urgency of economic development, few institutions, including the state, have intended to make significant investments in this area.
