Chapter 775

In fact, according to Professor Liu's position, there is no need to "lick" the boat.

It's better to have your own laboratory and do your own projects than to work for others.

However, nothing can escape the word "Zhenxiang".

With only one word, Lu Zhou asked him to pack things without saying anything

“…… This time I can't help you, but the next time, two years later, I promise you will become an academician, no big problem. "

For Professor Liu, who has no contacts outside the small circle of cryobiology, this commitment is enough

Jinling Institute of higher learning.

A laboratory in the most corner of the Institute of biochemistry.

Some of the equipment here was ordered by acquaintances from Germany and Holland, and some was simply moved or borrowed from the Institute of basic medicine of PLA General Hospital.

Although it's not right to do it programmatically, it's flexible. In particular, no leader of this research group will refuse this kind of achievement after putting up the sign of key projects of moon orbit construction committee.

As long as a signature is signed, even if it supports the national key projects, it is no different from Baiji.

Standing in the laboratory, Lu Zhou stared at the samples in several glassware in the refrigerated incubator for a while and asked.

"This is?"

Professor Liu Zuobing: "samples of ancient nematode cells! The research team at the University of St. Petersburg collected it from the tundra of the alazea river. Because I had a good relationship with the professors there, I spent a little money to buy it from them. "

The boat asked casually.

"How much is it?"

"It's not expensive, just one hundred thousand dollars."

One hundred thousand dollars

It's not cheap to buy such a few samples.

If you remember correctly, this thing is not an endangered species, mainly in the feces of paleontology. As long as the migration route of paleontology or ancient river bed is determined in the frozen soil zone, a shovel of soil may be able to get a pile of samples.

Spend 100000 dollars to buy this thing. I'm afraid that all the funds for other people's scientific research activities will be covered.

It seems to understand the sympathetic sight of Lu Zhou, Professor Liu Zuobing explained with a light cough.

"A hundred thousand dollars is not too much! As the saying goes, rare things are precious. According to the carbon isotope detection, about 40000 years ago. We want to make this kind of thing ourselves. Maybe it can only be found on the plateau. It's not necessarily that complete... "

Lu Zhou: "point out, I don't know much about paleontology."

Professor Liu Zuobing nodded and continued with a serious expression.

"This is probably the first living biological sample that we can get at present. After obtaining the sample containing frozen nematode from the research team of the University of St. Petersburg, we took out some complete nematode cells and transplanted them to a special culture dish for enrichment and culture, and found a very magical phenomenon."

Zhang Jiafu, who was listening to Lu Zhou carefully, couldn't help asking.

"What phenomenon?"

Professor Liu Zuobing said in a serious way: "in 173 Petri dishes, 2 of them observed the recovery of nematode cells and the resumption of normal life activities!"

Hearing this sentence, the expression on Professor zhangjiafu's face was immediately wonderful.

"Are you sure it's not mixed with pollutants? There's no problem with the samples from the University of St. Petersburg? "

Professor Liu Zuobing continued in a positive tone: "I can be sure, because they went to the permafrost investigation group, and my students were present."

"It's me," Song Siyuan, standing next to Professor Liu Zuobing, raised his hand, looked at his tutor and said nervously. "I took these samples myself, and the photos were there."

Lu Zhou asked inexplicably on his face: " Why do you have to pay 100000 dollars? "

Why should I pay for the digging by myself?

Professor Liu Zuobing's expression suddenly became a little embarrassed.

Fortunately, Professor zhangjiafu understood, coughed softly and said, "it's the way to cooperate with the maozi. They have a relatively poor life, so it's normal to spend a little money Can I have a look at the sample? "

Professor Liu Zuobing looked at him gratefully and nodded.

"Of course."

After taking samples from the dish with a special liquid extractor, Professor Liu Zuobing's assistant quickly made the samples into slide samples, which were then placed on the laboratory microscope.

Seeing that the specimen is ready, Professor zhangjiafu can't wait to step forward and stand in front of the microscope to observe it carefully.

Only these precious tiny creatures, floating in agar and special nutrient solution, are crawling slowly with Escherichia coli as food.

After five or six minutes of observation, he finally moved his face away from the microscope and said with emotion."This discovery is amazing So the University of St. Petersburg gave you the research results? "

"Of course not. All papers are theirs, but I haven't continued to cooperate with them in the follow-up research," said Professor Liu Zuobing with a smile. "For example, the retrieval of DNA fragments of nematodes I guess they've been doing it all the time, but they haven't seen much

Upon hearing this, Professor Zhang immediately got up in spirits and asked in a hurry.

"What did you find?"

"By studying the DNA of nematode samples, we found that on the 18S rDNA gene fragment, there may be factors that can allow them to sleep actively in extremely cold environment!"

This time, not only zhangjiafu, but also Lu Zhou's face showed a somewhat surprised expression.

DNA fragments related to freezing dormancy!

This discovery is amazing.

"Did you publish it in the journal?" Lu immediately asked

"No," Professor Liu Zuobing shook his head. "It's just a phased achievement. We firmly believe that the Russians didn't find this, so they didn't publish it."

This kind of operation is very common in academia.

Lu Zhou himself didn't do it, so he nodded in understanding.

"I know the situation. Now I want to listen to your experimental ideas. Can you simply tell me about it?"

Professor Liu Zuobing nodded and said.

"18S rDNA gene fragment may be the key to solve the problem of freezing dormancy. At present, we speculated two possibilities. One is that the 18S rDNA gene fragment synthesizes a special protein through transcription RNA, which makes the cell suspend life activity under extreme climate conditions and maintain the normal basic structure of the cell!"

It sounds exciting.

However, there was no obvious expression of excitement on Lu Zhou's face. After thinking for a moment, he said, "but there are still many cells dead."

Professor Liu nodded and said.

"Yes, not every individual can survive, because they are not only suffering from severe cold on the frozen soil Of course, none of this is the point. The point is that we have two ideas. "

After a pause, he went to the white board of the laboratory, drew two lines on it, and wrote next to one of them.

"One is to insert potentially effective gene segments into the gene segments of living organisms through gene editing, so as to achieve dormancy in the frozen environment!"

After thinking for a moment, the boat asked, "what's the other way to experiment?"

The marker in his hand points to the narration of another line, and Professor Liu Zuobing continues to open his mouth: "the other way is to completely immerse the human body in the slow-release agent containing the protein substance by the way of drug induction, using the research idea similar to that of Professor glonster!"

Professor Zhang Jiafu: "like formalin?"

Professor Liu Zuobing nodded: "it can be said, but it must be different from formalin..."

Standing beside the whiteboard, Lu Zhou stared at the two lines and thought for a long time.

After about five minutes, he said.

"It sounds crazy, but I think the latter can try it."

Professor Liu Zuobing nodded.

"I think so too. The way of gene modification It's too expensive to succeed or not. "

And the most important thing is that the study of human DNA modification is not allowed by moral ethics.

What's more, unlike the controversial technology of freezing and dormancy, there is no dispute that it's against ethics. Whoever does it is anti human

This kind of extreme research, let alone he dare not easily surmount, even Professor Lu dare not let him try.

Just then, there was a knock at the door.

After getting permission, the office assistant of Lu Zhou pushed open the door and came in.

"Professor, someone is looking for you."

Looking for me?

Lu Zhou recalled carefully. He didn't remember who he had an appointment with today, so he asked.

"Who?"

Said the young assistant, with a delicate expression.

"The visitors call themselves Professor Angus Deaton of Princeton It seems that he is in a hurry? "

Angus Deaton?

Lu Zhou is a little impressed by this name. I vaguely remember that it's an economics school. Although Princeton doesn't have a business school, it has an economics department, and its influence is not low. Theoretical economics, in particular, ranks very high in the United States, and many of the lists even stand at the top 1 position.

However, Lu Zhou had never studied economics before, so he didn't pay much attention to this aspect.

So he couldn't think of any reason for this professor Angus to visit him.After thinking for a while, the boat said.

"I see. Let him wait for me in the reception room for a while."

The assistant nodded.

"Yes, professor."

Then she turned and walked out the corridor.
