By the time the spiced and salted pork ribs were served, Zhu Jiahao had already finished a bowl of rice.

Yang Rui also ate up a bowl full of rice. In this era of no computer, no TV programs, and no paperless office, everyone consumes a lot every day. Of course, good taste is also very important.

"Another bowl?" Without waiting for Zhu Jiahao to answer, Yang Rui offered another bowl of rice to him.

Zhu Jiahao was a little embarrassed and said with a smile: "I didn't have breakfast..."

"It's OK. We eat casually in the Research Institute. We can eat whatever we want and whenever we want." Yang Rui added a bowl of rice to himself, and then gave Zhu Jiahao a piece of spareribs. He said: "it's very hard for everyone to do experiments. Sometimes when an experiment is finished, the meal is missed. You can't punish people who work hard, can you?"

Zhu Jiahao nodded and said, "we also put some things in the laboratory, such as bread and steamed bread. If we give them to those who miss the restaurant, there will be no fried dishes."

"That's because Richard is a foreigner. They feel comfortable eating bread and butter. We Chinese are still used to eating fried vegetables, rice and noodles, right?"

"That's right. I often want to eat some staple food, and then I'm left with bread. At the beginning, I thought the bread was very fresh. I didn't want to eat it after two times. " Richard's laboratory is well paid, especially in terms of material conditions. Peking University provides what it needs as much as possible. Richard also subsidizes other researchers and interns with the funds of the University of California. This is one of the reasons why people including Assistant Professor Liu can work more than 12 hours a day.

Yang Rui put the rest of Mapo Tofu into his bowl and the rest of stir fried meat into Zhu Jiahao's bowl. At the same time, he said with a smile, "foreigners' working habits are different from those of us Chinese people. There are many places that we are not used to when we work under foreigners. I have such a feeling when I contact people from Jielikang. Some of them are very serious, and they are so critical, There are some places that are too lax to be seen. "

"Yes, Richard's student, Connors, keeps emphasizing the cleaning of mice, and then he stinks." Zhu Jiahao said with a smile.

Yang Rui also laughed and said, "we can't blame him for this. Our bathing facilities are backward and foreigners have a strong body odor. This is the result of not taking a bath."

"He stinks and is often idle. We don't like sanitation." Zhu Jiahao is an outspoken person. He speaks all his dissatisfaction with his classmates directly. But it's not easy for him to communicate with foreigners in English. It's not enough to complain, so he has accumulated all his dissatisfaction.

Yang Rui is like a bosom brother. His tone slows down and guides Zhu Jiahao to speak with ease.

This is the skill he learned as a cram school teacher. Although the cram school is a little rough, he also needs to understand the mental state of the students. Especially after starting his own business as a cram school, he has to regulate the behavior of the students in the cram school. In the face of bear children in the 21st century, the skill of chatting is very important.

Zhu Jiahao first felt that Yang Rui's voice was kind. Today's primary and secondary school teachers are pursuing the principle of filial piety under the stick, occasionally kind, let the students move the heart. There are many brothers and sisters in Zhu Jiahao's family, and his parents don't have the time and energy to talk with him. Yang Rui's voice is full of magnetism, like a baritone. Following the good advice, he immediately makes Zhu Jiahao feel that chatting is a pleasant thing.

Yang Rui asked about the mouse again. Zhu Jiahao said everything. From his point of view, it's too normal to use the mouse for biological experiments. Yang Rui and he said this, which made Zhu Jiahao relaxed.

In fact, when Yang Rui confirmed that Richard's laboratory had only mice, he was immediately relieved and discussed them with Zhu Jiahao until Zhu Jiahao had nothing to say.

Cloning mutation gene of potassium channel needs to induce biological gene mutation. As far as Yang Rui knows, the simplest and quickest way is actually fruit fly.

Drosophila is a common experimental material in genetics. There are many genes screened out by Drosophila, such as genes controlling cone cells, genes regulating biological rhythm, genes determining time concept, and genes of leg shaker discovered later. When the gene of leg shaker mutates, the small and thin legs of Drosophila under anesthesia will keep shaking, This is because the genes of leg tremblers control the potassium channels of cells, which are closely related to the activities of nerve cells.

Of course, although Drosophila is a good material for studying genetics, it is also one of the most thoroughly studied organisms by human beings. However, Drosophila is not the only experimental material for studying genetics. Therefore, it is very normal for Richard to use the commonly used and classic mouse.

However, compared with the reproduction speed of Drosophila, it must take more time to screen out mutant genes from mice.In future papers on potassium channels, there are Drosophila melanogaster, mouse, plant and other mammals. Different results can be obtained by using different organisms. Some results are also very important. However, the importance of these conclusions can not be compared, and a large number of citations mean popularity in the scientific community. In the case that each researcher has to read hundreds of papers for an average experiment, a paper with 10 citations has been read by at least thousands of researchers, and 30 citations are well known in the field.

Yang Rui's pursuit of nature is the first paper. Otherwise, he would not be interested in doing this experiment.

Richard, in fact, is the same. A distinguished professor at the University of California, Berkeley, gave up the excellent experimental environment in the United States and came to China to set up a laboratory. Naturally, this is not the spirit of internationalism, it is looking at hundreds of influencing factors.

It's no problem for Richard to become a tenured professor when such a paper is published.

Obviously, if you can do a high-end thesis, it's just as difficult as shooting in the restricted area. You should not only consider the time and competitors, but also the angle and strength.

Using mice to do experiments, the force is absolutely enough, it can also more easily prove the role of potassium channels.

However, it is not easy to select the angle of inducing gene mutation in mice.

Yang Rui intentionally or unintentionally said something about the mouse experiment. This time, he was sure that it was all the same knowledge, but Zhu Jiahao listened very seriously.

He naturally thought that Yang Rui must also be doing experiments with mice.

Holding a cup of tea after dinner, Zhu Jiahao can't help falling into a dilemma: if he tells Richard all about it, he may get Richard's praise and maybe get a bonus, but he doesn't like this kind of behavior.

However, if not, Zhu Jiahao feels ashamed of his work. After all, he is an intern in Richard's lab, and the intern is also a member of the lab.

"Well, I have to go." Zhu Jiahao's tangle was almost written on his face. He was afraid that Yang Rui didn't understand. He said, "I'm going back to Richard's lab to work. It's very troublesome for Richard to ask."

"Go back now? We have cars to pick up schools and downtown in the evening. " Yang Rui's car is still a jerichon car. It's very convenient for foreign-funded enterprises to get car license plates, but it's troublesome for private enterprises to buy cars.

Zhu Jiahao was even more embarrassed. He even said no, and said, "I came by bike. I'd better go back by car."

"Put the bike here, and come to get it next time."

"No, I've eaten so much. I've got plenty of strength. I'll go. Goodbye." Zhu Jiahao doesn't know what else he can say if he stays. He doesn't want to know more about Hua Rui, and he can't tell the secret of Richard's lab. Although he said some information about Richard's lab, in Zhu Jiahao's opinion, Yang Rui already knew it, so it seems that it is not a secret.

Riding on his bicycle, Zhu Jiahao secretly decided that unless he was asked, he would not have been to Huarui laboratory.
