The specifications of the commendation meeting were upgraded very quickly, from the small program of the department at the end of the semester, to the important work at the end of the semester, and then to the important work of the school, only two days passed.

At the same time, the number of people participating in rehearsals is increasing.

Originally, the Department of Biology selected 8 people, but now it has become a school-wide commendation meeting, and the number of people has increased to more than 90 people in one go, which is deliberately limited to avoid the number of people exceeding 100.

Of course, the rehearsal time has increased as a result.

The eight people who will be honored in the Department of Biology are happy, but they still feel that the rehearsal is hard.

Xu Anqing was even more opinionated, and at the end of the day, he couldn't help asking, "Why didn't Yang Rui come?"

He gestured to the banner above his head to show that he was being reminded.

Today's person in charge is no longer a cadre of the student union, but a counselor of the biology department, Bai Shanwen.

He let out a "hmm", shook the black mole on his mouth without any expression, and said, "Yang Rui is busy, and when we finish rehearsing, he will come over to rehearse." ”

"We're busy, too. Xu Anqing was so unhappy that he vented it.

Bai Shanwen smiled: "I know, everyone is very busy, so let's hurry up and rehearse, right." Yang Rui is not in school now, and it is useless to call him. Anyway, I'll keep him from holding us back. ”

Speaking from a different angle, it sounds like Bai Shanwen is very considerate of everyone.

Xu Anqing naturally wouldn't be fooled by him, but in the current situation, he couldn't do anything.

The frustration of powerlessness will turn into anger.

Xu Anqing kept comparing himself and Yang Rui, and asked himself for the first time: "Where am I wrong?"

There was no answer to this question, and everyone continued to rehearse, and Xu Anqing had no choice but to follow suit.

Yang Rui followed Professor Cai and demonstrated the PCR instrument to him in the laboratory.

As a practical technology in academia, it is the same as a practical technology in the business world, and it does not need to be unclear about all functions.

It's like a refrigerator, if you want to say it's simple, it's just for refrigeration. As for what to do with refrigeration, this is a small skill for home or business, you can use it to put leftovers in one way, use it to make ice cubes and drink wine in one way, and use it to put bacteria in the culture medium.

It can also be taken out thousands of times by X-ray, orthopedic films, oil paintings to see delamination, and DNA.

And such a technology, when it first appeared, it is impossible to say who could have foreseen it.

It can only be said that people can see that it is extremely scalable.

As for the degree of expansion to the oven, the degree of the refrigerator, the degree of X-ray, or the degree of the computer, no one can predict, and many times, further development also requires creativity, just like the inventor of the water bath, who will not know that the water bath can be changed and made into a PCR machine.

Of course, there is no patent conflict between a PCR machine and a water bath, and the latter cannot even be counted among them, because the core of the patent is not about boiling hot water, or thermostatically controlled water.

Even after 30 years, the potential of the PCR machine has not been exhausted, in other words, Yang Rui does not know how much the PCR machine can do in the end, and this is the strength of the PCR.

In fact, PCR won the Nobel Prize in 93, only four or five years before the advent of the PCR instrument, and only seven or eight years after the invention of PCR technology......

All in all, the development of PCR, like its function, starts with a small and small point, and expands much faster.

Before, Academician Cai thought that PCR was a good technology, but he didn't think it could be any better, and the PCR machine had not yet been made, so Academician Cai didn't think much about it when the research field was not in the genetics.

Now, Yang Rui's achievements in the "International Congress of Genetics" have made Academician Cai have to study PCR carefully.

For a scholar of his level, doing good research is not just about reading the literature, and the experiment is not just about doing two.

Professor Cai set aside a whole day to make an appointment with Yang Rui to come to Sinovel Laboratory.

Yang Rui also waited respectfully, and now, he was not worried about leaking some experimental content, because Δ was very generous to put all kinds of instruments away.

Duan Bo and others are also instruments of Yishui, preparing to do multiple experiments at the same time.

Yang Rui started with the simplest plasmid amplification, demonstrated it to Professor Cai, and said: "After we do some more in-depth research, we should be able to replicate human DNA, such as extracting DNA from hair strands, and then amplifying, which cannot ......be done for the time being."

"That said, your research has been endorsed by Professor Evans. "Professor Evans' research in genetics is impressive, and his judgment is well known in the industry. ”

"Really?" Yang Rui knew that Evans was very good, but he didn't know the direction of his cow.

Professor Cai nodded, and said, "Can I do it myself?"

"Oh, please. Yang Rui hurriedly made way out of the place, and then called Huang Mao to come over for guidance. After all, his status is a student, and he is not suitable to directly supervise Professor Cai.

Professor Cai continued to do the experiment step by step, and when he took a break, he observed this Sinovel laboratory.

Yang Rui was surprised by his feelings, and asked in a low voice, "Do you see any problems in the laboratory?"

"No, very good, it's expensive. Professor Cai said, "It just complements your ion channel laboratory. ”

Yang Rui's ion channel laboratory is still a high-quality stream, and the expensive instruments bought to do some experiments that are not often done, in contrast, the Sinovel laboratory is set up little by little, and naturally the guy has a lot of things, and it is completely able to undertake multiple sets of experiments, and there is already a tendency to large laboratories.

Yang Rui shrugged his shoulders indifferently and said with a smile: "This is no way, if you allocate me another million, I can buy a good set of instruments." ”

"Okay. Professor Cai replied with a smile.

"Hmm, hmm?" Yang Rui stared at Professor Cai with wide eyes, "The school is so rich?"

It is not easy to say that after 2000, it is not easy for a department of Peking University to get millions of dollars, I am afraid that it will not be until 10 years later, it will be easy to allocate millions of dollars to a laboratory, as for now, in 84 years, millions of dollars can be seen by academicians, like Professor Tang Zhong, who will guard millions of funds a year, and then apply for a national laboratory.

Professor Cai did the experiment, did not look up, and said: "You don't need me to give you money, if you can pass the national achievement certification, I can help you find money." ”

"How many can you find?" Yang Rui didn't know if it was bad when he heard the word "national", so he asked about the benefits first.

Professor Cai said as usual: "The minimum is one or two hundred thousand, and the most is three or five million, depending on how it is assessed." ”

"How much do you think I can rate. ”

"It depends on the work done upfront. Professor Cai didn't say much, and once again concentrated on the experiment.

In the afternoon, Professor Cai picked up the experimental record written by Shi Cai, looked through it, and said, "Yang Rui, let's go out for a walk?"

"Oh, okay, it's a little stuffy inside. Yang Rui followed Professor Cai out of the door in a daze.

Outside the Sinovel Laboratory, which is still a wilderness, the two walked up a hill along the path before they heard Professor Cai say, "Do you have a high income in the Sinovel Laboratory?"

"Ah...... It seems to be okay. Yang Rui didn't know why.

"Is there a burden at home?"

"This ...... Probably not. ”

Professor Cai nodded and said, "I've read your file, your father is the secretary of the township party committee, if you don't have a burden, you shouldn't have to worry about anything, right?"

"That's pretty much it. ”

Professor Cai nodded and said: "The economic foundation determines the superstructure, I am here to tell you, let's talk in private, it is difficult for the children of the poor to do scientific research, especially the children from poor families in China, it is not suitable for scientific research, it is too bitter!"

Yang Rui was silent.

Professor Cai continued: "To do scientific research, you have to study, during the study period, not only there is no income, but also expenses, you graduated from university, the younger ones are 212 years old, and the older ones are 24 or 5 years old, at this age, if you go to the government and go to the factory, you are very promising, but in the scientific research community, the bachelor's degree is not enough...... The conditions in our country are relatively poor, few people can study for graduate school, doctoral students, going abroad is the only way out, however, even if you go abroad and come back, it is not easy to have a lot of income, and during this time, you are unable to take care of your family, the old Chinese saying goes, parents are not far away, it is because of the dilemma of having children who want to raise and not being there......"

The reason why he finished his master's degree and did not continue to study was that on the one hand, the road to scientific research was difficult, and on the other hand, he did not experience the dilemma of economic pressure.

China's doctoral students are not delayed for a year, and they all graduate at the age of twenty-seven or eighteen, but in this ideal state, there is not one out of ten doctors. Most of the PhDs are about 30 years old, and they are still working hard in the laboratory with the title of Ph.D. students.

Unlike undergraduates, there is not much time and energy to work part-time, so almost all doctoral students in China live on a subsidy of 600 yuan to 1,200 yuan.

A 30-year-old man, living with 1,200 yuan, if he talks about a girlfriend again, it is unimaginable to be poor, and if the family still has a burden, then the entire doctoral career, in terms of life, can be miserable.

On the contrary, if the family can have some subsidies, it will be much easier and more relaxed to study for a doctorate.

Professor Cai was not ready to ask Yang Rui to answer, he looked at the young Yang Rui, waited for him to digest his words, and said: "The reason why I am telling you this is because the evaluation of achievements costs money, and if you want to evaluate a good result, you need to spend a lot of money." So, there are two questions here, first, do you have any money, and second, are you willing to spend it. ”

Yang Rui finally understood, and asked softly, "Do you have to spend money?"

"It can't be said that it is necessary, the evaluation of results, it is possible to succeed without spending money, but ......" Professor Cai smiled: "If you want millions of funds, I suggest you don't waste time at will." ”

"If the national-level achievement recognition is confirmed, then it is a recognition of my invention rights, discovery rights, patent rights, etc. for PCR, right?"

Professor Cai didn't care about what he said, and said with a smile: "More importantly, if you want to award your achievements in the future, you need to be recognized for your achievements, and many awards will have requirements, such as provincial and ministerial level achievement recognition, county and district level achievement recognition, etc., the national achievement recognition is the most stringent and the most useful, and your laboratory rating, etc., can be used." ”

"But PCR, I did it at Sinovel Labs. ”

"The identification of the unit is one thing, and the identification of the individual can be taken away, otherwise, if I change schools, do I have to start from scratch?" Professor Cai laughed.

Yang Rui breathed a sigh of relief and asked, "How much money do you want to prepare?"

The landlord's family also has no surplus grain, and he is also short of money before recovering the PCR bill or dividends.

Professor Cai shook his head and said, "It's not just about money, it also takes a lot of energy, you have to be prepared." ”
