Rebirth of the God-level Xueba

After the surprise created by Yang Rui, the field investigation led by Professor Xie Gaoyi did not yield any more results. network

This is also a very natural thing. The discovery of new species is not difficult to say, easy to say.

If we organize a survey of species in Shennongjia, or a survey of the distribution of underwater organisms, it is only natural to find dozens of new species, but in the main teaching area of ​​hundreds of colleges and universities in Beijing, Badaling forest area, I want to find one New species, it's pure luck.

Or Goldfinger.

Yang Rui undoubtedly took over the achievements of later generations, but from an academic point of view, this has no effect.

This new plant of the genus Bluethorn was originally discovered during a field screening in the Badaling forest area. The so-called screening is naturally not as simple as a field survey. It is a bit too much to describe it as a net-like patrol, but from the perspective of wild creatures, its scale is almost the same, it is nothing more than a continuation of the large mesh.

This kind of field screening will collect a lot of plant specimens. As for whether new species can be discovered, in fact, more depends on the analysis and identification of the standards by scholars.

As Professor Xie said, there are tens of thousands of specimens waiting to be inspected at Peking University alone. If scholars have enough time, dozens of new species, or even hundreds of new species, will be found in it. possible.

However, there are many biology enthusiasts, but there are only a handful of taxonomists who are really capable of making identifications.

However, Yang Rui's newly discovered plant of the genus Bluethorn can naturally be given priority identification by Professor Xie. Not only Yang Rui wanted to know the result, but the other 24 students who were traveling with him also wanted to know whether new species would be born.

Discovery of new species, although it is very common in academia, seems to be a very important matter in the eyes of laymen. After all, ordinary people do not understand the significance of the functionality of ion channels. But ordinary people often regard the discovery of species as very important, as if the discovery of a new species will make human biological science a big step forward.

For the students, if Yang Rui can discover a new species, everyone will at least get a new talking point. The Chinese New Year is about to come, this time I go home, but I can tell the seven aunts and eight aunts about my college life.

Otherwise, every time I go back, I will say that I have learned to do electrophoresis, and everyone will not take it seriously-swimming in electricity is nothing more than a courageous thing. Are there few young people who are bold and reckless in the village? Maybe this classmate will be warned by the village head: You are the only college student in the village, so you can't risk your life just to practice courage.

All in all, the students came to the ion channel laboratory with curiosity.

Not only the students who went to participate in the field investigation, but also many students in the Department of Biology who received the news. There are many people who are curious about this new species that may be the first new species discovered by the students of the Department of Biology of Peking University.

The reason for the identification in the ion channel laboratory is also very simple, Yang Rui decided to use pcR to identify the source for the first time.

It has been two years since Yang Ruiming developed pcR technology.

In taxonomy, biological genetic material is used, and taxonomy is to find homologous organisms. Therefore, experts in taxonomy began to use it more than a year ago; however, for the Chinese academic circle in the 1980s, two One year, but it is so short, not to mention popularization, and the attempt has just begun. The domestic pcR instrument is simple, but the reagents and the like cannot be said to be cheap. Most importantly, most scholars still have The state of learning imported knowledge in the past few years is like high school students ignoring changes in college textbooks, and the overall change in domestic biology is still slow.

As a professor of the Department of Botany at Peking University, Professor Xie also wanted to use his relationship with Yang Rui to start learning from scratch this time; therefore, after a small amount of communication, Professor Xie directly brought the specimens to Yang Rui's laboratory.

The students also rushed in.

Xu Anqing stared at the ceiling of the ion channel laboratory in a daze.

In the refurbished ion channel laboratory, the floor is clean and bright, and the ceiling is also made of composite materials, which is completely different from the common cement roof or white paint.

Of course, such a level of decoration is not considered Xiang, Xu Anqing has been to many places.

However, thinking that this place is actually Yang Rui's territory, and that Yang Rui is actually the person in charge of this laboratory, Xu Anqing feels very strange.

"I was also second in the national college entrance examination." Xu Anqing recalled the past inexplicably. What to say, Xu Anqing, a junior, has not thought about the college entrance examination for a while. His college career is very smooth. Of course, it is not as good as Yang Rui, but it is also very smooth. He has also published papers in academic journals. Although it is a Chinese journal, it is still an achievement that only a few people in Peking University can achieve. In addition, Xu Anqing is also the winner of the school and even the national scholarship. His academic performance has been kept below 5% of the grade for a long time. In the grade with less than 100 students, this means that he is always the top five in the grade.

Unlike 30 years later, student performance in the 1980s is very valuable. First of all, from the most utilitarian point of view, academic performance can determine graduation distribution, and it has a very large weight. Under the state's allocation policy, it is not easy for any unit to allocate college students. It requires competition and scrambling. When they finally get the allocation right, they naturally hope to get good students.

For more popular positions, such as government agencies above the ministerial level in Beijing, if they recruit students from ordinary key schools, they basically only need top students, and at Peking University, students who rank 20% in their academic performance can rely on top students. Successfully go abroad and get a full scholarship to the destination country.

As far as the environment in the 1980s is concerned, no matter which one it is, it will completely change your life, and in the next forty or fifty years, you will live a life that is completely different from that of students with ordinary grades. Do it, no stealing, no robbery, no corruption, five houses before retirement.

In addition to academic performance, Xu Anqing's social activities are also going smoothly. Although her family background inevitably helps, she was able to join the party in her junior year, successfully entered the student union, and then became the head of the logistics department of the student union. He has done a lot of work. As a member of the Peking University Student Union, he also got the qualification to join the National University Student Union this year. As far as student organizations are concerned, he is almost at the top.

However, all these achievements, which would make Xu Anqing a little proud, were overwhelmed by a ceiling with no design.

The ion channel laboratory, which has been established for more than two years, is showing its charm with a brilliant momentum.

X-ray biological diffractometer, flow cytometer, environmental scanning electron microscope, isotope ratio mass spectrometer, two-dimensional electrophoresis system, centrifuge, ion chromatograph

It is not necessary to know these instruments themselves, just looking at their shapes and appearances is already shocking enough.

And imitating the design of the first-class laboratories in later generations, today's ion channel laboratory behaves like a mockery in a sci-fi movie. In fact, students in the 1980s did not have the opportunity to watch any sci-fi movies. There are sci-fi machines, but , no matter how they imagined, I'm afraid they couldn't imagine how magnificent a laboratory was built at a cost of 4 million US dollars and 6 million yuan.

"Professor Xie, the electron microscope is here." Yang Rui briefly introduced the laboratory to Professor Xie and the accompanying students, and then pulled everyone to the experimental area.

The experimental area was a bit crowded, but fortunately it was quiet. Being in such an environment, everyone naturally became quiet and talked in low voices.

Xie Gaoyi nodded, came to the scanning electron microscope, looked at it for a while, and said a little embarrassedly: "This is Shimadzu I4oo's electron microscope, I haven't used it yet."

"Let Zhang Xuetong help with the operation." Yang Rui called Zhang Xuetong over as he spoke, and only then did the formal identification work begin.

Microscopic identification was the most common form of morphological identification until identification was achievable.

Although most species are quite alike at the macroscopic level, so that it is difficult for ordinary people to distinguish them, but at the microscopic level, the difference in microstructure is huge, and they can be distinguished without special training.

Xie Gaoyi began to observe with great interest, and while observing, he hand-painted the images, which was ridiculously strong.

It doesn't take him too long to paint, the shape of the new plant is displayed, and anyone with a discerning eye can see the similarities and differences of the stems and leaves.

"Yang Rui, I think you can start thinking about naming it." Xie Gaoyi was in a good mood and gave Yang Rui a reassurance.

The voice of discussion involuntarily grew louder.

Even Bai Ling looked at Yang Rui in surprise.

This luck is too good.

Yang Rui asked unconsciously: "What are the requirements for naming?"

"Now we use the double name method. The official name has to be in Latin. It doesn't matter. I will translate it for you. Let's start with the Chinese name. It belongs to the genus Bluethorn. This cannot be changed. You can choose it. It can be modified with a name, it can be a shape, a place name, or a person’s name.” When Professor Xie mentioned the name, the students around were all excited. I am concerned about the name of the plant, but what if it can be used as medicine.

Think about it, if you drink ten grams of ginseng with three cents of angelica and two Yang Ruilan thorns as a medicine primer, you will get rid of any cold.

"Let's stab Zhang Feilan." Yang Rui's voice interrupted everyone's imagination.

Professor Xie asked as if he didn't hear clearly: "Who do you want to commemorate?"

If it is not your own name, it is usually to commemorate someone.

Yang Rui shrugged and said: "I modified it according to the shape. The hair around the stem and leaves is very similar to Zhang Fei's beard."

Professor Xie was in a bad mood, and hurriedly said, "Don't be in a hurry to name it, don't be so hasty."

"Not rashly, I've thought about it a long time ago, so I'll use this name." In Yang Rui's mind, a question has already come up, which of the following four is not named after a person: Zhang Feilan, **** Lizards, quack ferns, bush beetles.

Yang Rui even thought of a reference answer: The distraction item for this question is the bush beetle. In English, bush means a shrub. Students who are interested in this item, please do not write English homework in biology class!
