Rebirth of the God-level Xueba

The field survey led by Professor Xie Gaoyi did not yield more results after Yang Rui’s surprise. network

This is also very natural. The emergence of new species is difficult to say, but simple is not simple.

If you organize a survey of species in Shennongjia, or a survey of the distribution of seabed organisms, dozens of new species are now natural. But in the main teaching area of ​​hundreds of colleges and universities in Beijing City, Badaling Forest District, I want to find one. New species, it's pure luck.

Or cheat.

Yang Rui undoubtedly took the results of future generations, but from an academic point of view, this has no effect.

This new plant of the genus Blue Acanthophyllum was originally discovered during a field screening conducted 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 a dragnet inspection, but from the perspective of wild creatures, its scale is almost what it means, nothing more than a continuation of the mesh.

This kind of field screening will collect a lot of plant specimens. As for whether new species can be discovered, in fact, it is more for scholars to analyze and identify the standards.

As Professor Xie said, Peking University alone has thousands of specimens waiting to be examined. If scholars have enough time, dozens of new species, even hundreds of new species, will appear in them. possible.

However, there are many biological enthusiasts, but there are only a handful of taxonomists who are truly capable of doing identification.

However, Yang Rui's newly discovered blue spiny head is a new plant that naturally gets the priority identification of Professor Xie. Not only Yang Rui wanted to know the result, but the other 24 fellow students also wanted to know whether a new species would be born.

New species or something, although it is common in academia, but in the eyes of laymen, it seems to be a very important thing. After all, ordinary people don’t understand the significance of the functionality of ion channels. However, ordinary people often regard the appearance of species as important, as if a new species has taken a big step forward in the level of human biological science.

For the students, if Yang Rui can discover a new species, everyone will at least get a new talk. Seeing that the New Year is about to come, this time I go home, but I can tell the seven aunts and eight aunts about their university life.

Otherwise, every time you go back, you will say that you have learned to do electrophoresis, and everyone will not take it seriously-swimming in electricity is nothing more than a matter of courage. Are there still few daring young people in the village? Maybe this classmate will have to be warned by the village chief: You are the only college student in the village, so you can't give up your life for training.

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

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

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

The pcR technology has been two years from Yang Ruiming to the present.

The use of biological genetic material in taxonomy is to find homologous organisms. Therefore, experts in taxonomy began to use it more than a year ago; however, for the Chinese academic community in the 1980s, two Years, but it is so short, let alone popularization, the trial is just beginning. The domestic pcR instrument is simple, but the reagents and the like are not cheap. The most important thing is that most scholars still The state of learning the imported knowledge from the previous few years is like high school students who ignore the changes in college textbooks. The overall changes in the domestic biology community are still slow.

As a professor of the Department of Botany at Peking University, Professor Xie also wanted to learn from the beginning through his relationship with Yang Rui; therefore, after a small amount of exchange, Professor Xie came directly to Yang Rui's laboratory with the specimen.

The students also rushed in.

Xu Anqing stared at the ceiling of the ion channel laboratory dreamily.

In the newly renovated ion channel laboratory, the floor is bright and clean, and the ceiling is also made of composite materials, which is completely different from the common cement top or white top painted with paint.

Of course, this level of decoration is not considered Hunan, and Xu Anqing does not know how many places he has been to.

However, considering that this is actually Yang Rui's site, and that Yang Rui is the person in charge of this laboratory, Xu Anqing feels very surprised.

"I was also the second place in the national college entrance examination." Xu Anqing thought of the past inexplicably. If you want to say, Xu Anqing, a junior, has not recalled the college entrance examination for some time. 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 at Peking University can achieve. In addition, Xu Anqing is also a recipient of a school and even a national scholarship. His academic performance has been maintained before 5% of his grade for a long time. In a grade of less than 10 people, this means that he is always the top five in his grade.

It's not like 30 years later, student scores in the 80s are very valuable. First, from the most utilitarian point of view, academic performance can determine graduation distribution, and it has a very large weight. Under the national distribution policy, it is not easy for any unit to allocate college students. It requires competition and competition. When they finally obtain the distribution rights, they naturally hope to get good students.

For more popular positions, such as departments at or above the ministerial level in Beijing, if they are recruiting students in general key schools, they basically only require top students. At Peking University, students with academic performance rankings of 2o% can rely on top students. Go abroad successfully and get a full scholarship in the country of arrival.

As far as the environment in the 1980s is concerned, no matter what it is, it will completely change your life, and in the next forty to fifty years, you will live a life completely different from that of students with ordinary grades—any way can basically be Do it, do not steal, rob, or embezzle, five houses before retirement.

In addition to academic performance, Xu Anqing’s social activities are also going smoothly. Although his family background inevitably helps, he can join the party in the junior year and successfully enter the student union, and then become the head of the logistics department of the student union. Xu Anqing is also He has done a lot of work. As a member of the Students' Union of Peking University, he also got the qualification to join the National University Students' Union this year. As far as the student organization is concerned, he is about to reach the top.

However, with all these achievements, Xu Anqing's arrogant achievements would be made by Xu Anqing, but he was breathlessly pressed by a colorless ceiling.

The ion channel laboratory, which has been established for more than two years, is showing its grace with brilliance.

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

You don't need to know these instruments themselves, just looking at their shapes and appearances is already enough to shock.

And imitating the design of the first-class laboratory of later generations, the ion channel laboratory of today is even more like a mockery in a science fiction movie. In fact, students in the 1980s did not have the opportunity to watch any science fiction movies. Science fiction equipment is available, but No matter how they imagine it, I am afraid they can't imagine how magnificent a laboratory built at a cost of 40,000 US dollars and 60,000 yuan.

"Professor Xie, the electron microscope is here." Yang Rui briefly introduced the laboratory to Professor Xie and the students who came with him, and brought everyone to the experimental area.

The experimental area was a bit crowded, but fortunately it was quiet. In such an environment, everyone naturally became light-handed and talked in a low voice.

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

"Let Zhang Xuetong help with the operation." Yang Rui said, calling Zhang Xuetong over, and then the formal species identification work began.

Before identification can be achieved, microscopic identification is the most commonly used method in morphological identification.

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

Xie Gaoyi started observing in high spirits, and while observing, he hand-painted the image, which was very outrageous.

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

"Yang Rui, I think you can start thinking about it and give it a name." Xie Gaoyi was in a good mood~www.readwn.com~ gave Yang Rui a reassurance.

The voice of the discussion became louder involuntarily.

Even Bai Ling looked at Yang Rui in surprise.

This luck is also great.

Yang Rui asked unconsciously: "If you want to name it, what are the requirements?"

"Now the double name method is used. The official name is Latin. This is okay. I will translate it for you then. Let's start with the Chinese name. It belongs to the genus Blue thorns. This cannot be changed. You can use it. A name can be used to modify it. It can be a form, a place name, or a person’s name.” When Professor Xie talked about the name, the students around him were agitated, but this made his name alive, although there are not many people. I care about botanical names, but what if it can be used as medicine.

Think about it, ten grams of ginseng with three yuan of angelica and two Yang Ruilan thorn heads are used as a medicinal primer and drink it. You have to get rid of any cold.

"Zhang Feilan stabbing his head." Yang Rui's voice interrupted everyone's conjecture.

Professor Xie asked as if he hadn't heard clearly, "Who is it to remember?"

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

Yang Rui shrugged and said, "I modified it according to the shape. The hair around its stems and leaves resembles Zhang Fei's beard."

Professor Xie's whole person is not good, and he hurriedly said, "Don't rush to name it, don't be so hasty."

"Don't be sloppy, I thought about it a long time ago, so I'll use this name." In Yang Rui's mind, there was already an ulcer question. The following four are not named after a person's name: Zhang Feilan thorn head, ****** Lizard, quack fern, bush beetle.

Yang Rui even thought about the reference answer: The interference item of this question is Bush beetle. In English, Bush means bush. Students who have this item, please don't write English homework in biology class!
