"Come on!" The unexpected sweetness in the door seemed to be a bit different from the image of the young female doctor who imagined the reporter. After entering the door with such curiosity, the intimate and charming lady made the reporter shine. Liu Ying’s face was handsome, wearing a lively and beautiful red jacket, with a gentle smile on her lips and a unique look in her eyes. So capable and cool. Researcher at the Institute of Molecular Medicine, Peking University, international research scholar at the Howard Hughes Institute, and doctoral tutor at Peking University. Many titles and auras belong to the young female scientist who is only 29 years old.
Liu Ying's main research direction is cell stress and steady state regulation mechanism. “It’s how cells perceive their energy and the state of nutrients, and how to coordinate stress responses when energy or nutrient status is inadequate,” Liu Ying patiently explained. “These stress coordination responses for cells and The human body is vital. The imbalance of stress can lead to many diseases. Our research has theoretical implications for the treatment of metabolic-related diseases and anti-aging, and may also have application prospects for clinical transformation."
Engaging in research is like running a marathon, Liu Ying, who likes to run, and runs through some marathons. People who have run through the marathon have experience. After running to a certain distance, there will be a feeling of "can't run, don't want to run, legs and feet don't listen to". This phenomenon is called "crashing the wall." And doing research is like running a marathon, and you will encounter a moment of "crashing the wall." How did Liu Ying persist? As a successful young scientist, Liu Ying condensed her research experience into three key words – curiosity, diligence and thinking.
"The curiosity about the phenomenon of life is the core driving force for my research." For many people, "curious" seems to be synonymous with "small tastes," and is not a pivotal factor in difficult scientific research. But for Liu Ying, curiosity is the most precious flame in her chest, always giving her guidance and strength in confusion and darkness. "When we do experiments, more than 90% of the probability will be different from the experimental results expected beforehand." After the "hunt battles", the failures and accidents in the experiment are no longer the anxiety that Liu Ying is difficult to digest, but She paved the way to her success. But in the past, Liu Ying also faced the same emotional dilemma as many of her classmates.
"I am a kind of person who especially likes to set goals and plan for myself. When I first went to the United States to study for a Ph.D., I was as confident as the students I am now, and I have great expectations for myself. But like us. The kind of experimental science is actually a process of continuous experimentation. The result is often not planned if you want to plan. Therefore, the first two years of my doctoral study was not very smooth, and I could not do it after changing four or five topics. So all the pressures have come, I can't help but think 'why the doctor is going to postpone, I can't graduate', and the mood is also very affected." Talking about his own experience, Liu Ying brought people in the tone. calm.
"But since I have always had a strong curiosity about the nature of life phenomena, I have not given up, but through positive psychological adjustment, I have gradually gained a new understanding of doing research. When I face unexpected experimental results again, I no longer indulge in the frustration of failure, but look at it more rationally. The experimental result that is inconsistent with expectations is not a failure. It actually tells us a lot of information. And one day I knew that this road would not work, then I It is possible to go to a more correct direction one day earlier and may get a better result. This is not a bad thing.” Liu Ying said that her later experience also proved that such an idea is correct. "The first two years of trials are not all in vain. Through the accumulation of experimental techniques and thinking skills in the past two years, my progress in the next semester of the second year of doctoral studies suddenly became clear, and after about three or four months, I basically got it. The experimental results needed, and the article was successfully cast." After the teacher, Liu Ying also used her experience to enlighten students who encountered the trough.
Taking a good balance between scientific research and life, reading humanities books, learning cakes, and running marathons, these seemingly "useless things" are an indispensable part of Liu Ying's life. She said: "Doing so-called 'useless things', on the one hand, give yourself a 'empty' opportunity to adjust your status in a timely manner while busy research work; on the other hand, you can bring your own research. More inspiration."
In the usual communication with students, Liu Ying often uses their own feelings in life to give them guidance. “A lot of students have an 'illusion': they put their time every day, do a lot of experiments, and work seamlessly from morning till night, it seems that only then can they feel peace of mind and feel themselves 'There is no vain time'. But I told them that 80% of the experimental plans can be cut off, you just need to do the experiment that 20% really can go deep into your subject. It’s like we have to make a cake, This 20% of the content is the cake embryo, and 80% of the content is the silk flower on the cake. If you don't even make the cake embryo, then you are going to tangled to make icing, or cream, and what? What is the meaning?"
“Logical thinking is also very important.” Liu Ying believes that active and flexible logic analysis is crucial in scientific research. She said: "In our research process, we began to extract valuable hypotheses from the information, and then design follow-up experiments according to our own assumptions, and finally verify the experimental results, each step is interlocking. There is a meticulous logical relationship throughout. If you don't clarify these logics well, you will often get half the work and waste your time and energy."
This logical thinking is also reflected in many other aspects. Reading the literature is a compulsory course for researchers, but students often have some confusion about how to read the literature. In this regard, Liu Ying suggested that when reading the literature, do not “take the nose by the literature”, there should be a “questioning” attitude: not only to understand the knowledge background of the field, but also to clarify the design logic of the experiment in the literature. Learn the technical methods used by the predecessors; observe the details of the experiment, observe each experimental result graph, think about whether the experimental design itself is flawed, whether there is any improvement, or analyze the relationship between the experiment and the conclusion in the literature. See if there are any other possibilities.
Liu Ying picked up a thick notebook at hand and said: "I have specially prepared such a book, record my thoughts at any time, and look back every once in a while to find out if there is any research direction that can be tapped. Some of the ideas I thought of when I read the literature, some of which I wrote when I went to the scientific report." Liu Ying also encouraged her students to learn more about other areas of knowledge and research, because the intersection of disciplines is very important, can Enrich your thinking and inspire. She often said to the students: "You should not only listen to reports in our own research fields, but also participate in academic reports in other directions to learn the strengths and advantages of other research groups in the field."
Do not set a ceiling for himself In April this year, Liu Ying won the "China Young Women Scientist Award" jointly established by the All-China Women's Federation, the China Science and Technology Association, the China National Commission for UNESCO and L'Oreal (China) Co., Ltd. The award was established in 2004 to recognize women's young scientists and technicians who have achieved significant and innovative scientific and technological achievements in the field of science. It encourages young women scientists and technicians to contribute to the goal of building a well-off society in an all-round way and encourage more guidance. Women are engaged in natural science work.
Liu Ying told reporters: "Whether it is on TV programs or interviews, I have always hoped to use my own experience to motivate women who love science and technology, but who need courage: research and family are not a single choice. I also With a happy family, I am also enjoying the happiness of being a parent. You can find a balance between work and family. You have this ability."
Liu Ying believes that despite many difficulties, female researchers cannot retreat, and they must confidently demonstrate the unique advantages of women in scientific research and be brave in pursuing their own scientific research. Moreover, more and more outstanding female scientists will emerge as more and more women persist on the scientific research road and show their own style in society.
Just like Liu Ying said to his students: "You are likely, and you like it, then you don't force yourself, how do you know what level you can achieve?" China Army Network Beijing 6 On the 18th of the month (Reporter Wang Xuding Yang Song Lili), the four-day Armed Police Force "Great Wall-2019" Anti-Terrorism International Forum kicked off at the Armed Police Special Police Academy on the 18th. More than 240 representatives from similar missions from 31 countries including China, France, Israel, Pakistan and Uzbekistan attended the opening ceremony.
The forum aims to build a cooperation platform with counterparts from all countries, share the results of exchanges, jointly improve the ability to effectively deal with terrorist incidents, and safeguard their national security and social stability. Qin Tian, deputy commander of the Armed Police Force, said in his speech that we will work with other countries to create an international cooperation platform for the 'Great Wall' forum with open attitude and pragmatic actions, to exchange ideas, gather wisdom, and strengthen our efforts. The respective units fulfill their mission capabilities and better benefit the people of all countries.
The President of the Pakistan Army Special Operations School, Kasif, said that the "Great Wall" Anti-Terrorism International Forum is a unique and amazing platform that connects the ideas of various countries in the world against terrorism. When he first came to China, he is very much looking forward to discussing with the countries in the forum. Exchange and benefit each other. Based on the theme of promoting international cooperation against terrorism, jointly researching anti-terrorism methods and sharing theoretical and practical results, the forum organized five special seminars on the theme of "special attack", interspersed with sniper skills demonstrations, sniper equipment display and counter-terrorism training venue facilities. Visit and other activities.
This forum is the only multilateral international conference event hosted by the Armed Police Force this year. It is also the largest number of participating countries and the largest number of participants. In recent years, the Armed Police Force has organized the "Great Wall" Anti-Terrorism International Forum and the "Front Blade" International Sniper Shooting Competition and other activities, focusing on creating foreign exchange brands with Chinese characteristics and the characteristics of the armed police force, inspiring exchanges and mutual learning, and promoting trust and friendship. A positive and good international response.
At the same time, the Armed Police Force also actively participated in international competitions such as the International Special Forces Competition and the Hungarian World Military and Police Sniper Championships, strengthened joint anti-terrorism exercises with many national military and police, and fully learned from the advanced foreign anti-terrorism operational concepts to promote the anti-terrorism operations capability of the armed forces. overall enhancement. Lanzhou Evening News "My hometown is in Silong Town, Baiyin District, Baiyin City. I grew up on the Yellow River and I am still water-based. In the past few years, I have saved four light-hearted people from the Yellow River." On the afternoon of June 17, Wang Mingliang The reporter said. Wang Mingliang worked in a tea booth in Lanzhou. At 7 o'clock on the evening of June 16, he found a man floating in the Yellow River. He ran over more than 300 meters along the shore and jumped into the water to intercept and save people. In the end, with the help of another guy, the suicide was saved.
At 2 o'clock on the afternoon of the 17th, on the Yellow River under the bridge of the Tianshui Road exit highway, the reporter saw Wang Mingliang. He was embarrassed to say: "There is no need to promote the propaganda." At 7 o'clock on the evening of June 16, Wang Mingliang was working. Sitting in the tea stall, I suddenly found a person floating in the center of the Yellow River. He rescued many times and immediately realized that someone had jumped to the Yellow River to find a short-sighted one. The limbs of the light-hearted were still waving from time to time. "People are still alive, have to hurry to save the shore." Wang Mingliang said that because of the rapid flow of water, he quickly ran down the shore more than 300 meters. After discovering a wide river bank, he couldn't take off his clothes and take out his mobile phone. He jumped into the water to save people. He didn't expect the stones in the water to hurt his feet. Instead of catching the light man, he drank a few more. Saliva.
At this point, the light-hearted man drifted along the river to another piece of reed. Wang Mingliang rushed to the shore with a sharp pain, and caught the light man in the lower reaches of the road more than 10 meters. At this time, another boy on the bank also entered the water to help Wang Mingliang save the suicide man ashore. The enthusiastic citizen of the bank, Mr. Peng, had already dialed 110 and 120. The suicide man was then rushed to the hospital.
That night, Wang Mingliang and his friends rushed to the hospital to visit the suicidal man. The family expressed his gratitude for his courageous behavior. According to reports, the light-stricken man is about 50 years old. Because of the family's troublesome things, I can't find a short-sightedness at the moment. It is understood that from 2017 to now, Wang Mingliang has successfully rescued four light-sponsors from the Yellow River. He said: "As long as I see the drowning person, my first thought is to hurry and save the shore. For my own safety, there is no time to think about it, and I don't think much."
