On the morning of October 10, Li Jinsong, an academician of the Chinese Academy of Sciences and researcher at the Center for Excellence in Molecular Cell Science of the Chinese Academy of Sciences, walked into Chongqing No. 1 Middle School and gave a wonderful popular science lecture titled "From Cloning to Semi-Cloning - Technological Progress Leads Scientific Development" to more than a thousand teachers and students.

Academician Li Jinsong took the cloned sheep "Dolly" that shocked the world in 1996 as an example to explain the principle of traditional cloning technology in a simple and easy-to-understand manner - "like a complete photocopying process." He then led the audience into a more revolutionary new era of "semi-cloning" technology, vividly comparing it to "intelligent editing and reorganization." Facing the huge challenges of protein research in life sciences - that is, the preparation of traditional antibodies is cumbersome and half of the proteins do not have research tools, Academician Li Jinsong once again demonstrated his forward-looking scientific research vision. He proposed a "brain-breaking" solution - the "Genome Tagging Project" (GTP). He cleverly compared it: "This is like building the 'Beidou Navigation System' for life science research. By putting standardized 'tags' on proteins, we can quickly locate their location, interactions and dynamic changes in the body, greatly simplifying research. ”Academician Li Jinsong combined his own experience to encourage students to stay curious and be brave in exploration and innovation, which won warm applause from the audience.

On the morning of October 10, Professor Shi Yufang, academician of the European Academy of Sciences and dean of the Institute of Translational Medicine of Soochow University, walked into Chongqing No. 1 Experimental Middle School and gave a popular science lecture titled "The Legend of Stem Cells: Taming Inflammation and Initiating Repair" to more than 1,200 teachers and students in the school.

When the body sounds the “inflammation” alarm, we usually view it as an enemy that needs to be eliminated. However, in the eyes of top scientists, this microscopic battlefield contains the ultimate code for life's self-repair. Academician Shi Yufang started from the cutting-edge stem cell science and vividly explained how stem cells can precisely regulate inflammation like "smart drugs" and secrete signaling molecules to create a good environment for tissue repair and guide the body from chaos to order. Step into the legendary world of stem cells and discover how they act as "artisans of life" and accurately "decode" the complex signal of inflammation. Stem cells do not respond passively, but actively "tame" the out-of-control inflammatory storm into core instructions for initiating regeneration, thereby rebuilding health on the ruins of cells and turning damage into new life. Talking about the current status of scientific exploration, Academician Shi Yufang said that human exploration of the mysteries of life has so far only been the "tip of the iceberg." He used this to encourage the students present to study knowledge diligently and explore the truth of all things. The vast world of science in the future is waiting for them to explore.

On the morning of October 10, Professor Zeng Fanyi from Shanghai Jiao Tong University, chief scientist of the National Major Scientific Research Program (973 Project), walked into the Middle School Affiliated to Southwest University (East District) and gave a popular science lecture titled "The Double Helix of Life Sciences and Culture and Art: The Source of Inspiration and Creation" to more than 1,300 teachers and students.

The famous writer Flaubert once said: "The further you go, the more art must be scientific, and science must also be artistic. The two separate at the foot of the mountain and meet at the top of the mountain." ”Professor Zeng Fanyi believes that art is the depiction of life, and science is the analysis of life. Science and art are the collision of rationality and sensibility, rigor and romance. The two may seem incompatible, but in fact they are interdependent and mutually successful just like the double helix structure of DNA. The interaction between Professor Zeng Fanyi and his classmates was open and sincere, turning a short hour and a half into a pleasant journey of exploration. She encouraged the students to learn as much knowledge as possible in various fields and aspects, which will be of great help to their future growth.

On the afternoon of October 10, Professor Wang Jichang from Sun Yat-sen University walked into Xinfeng Primary School in Chongqing Science City and gave a popular science lecture titled "Opening the Boundaries of Imagination - How to Grow Human Organs from Pigs" to more than 200 teachers and students in the school.

When organ failure becomes a problem that must be faced, how should humans continue to live? Professor Wang Jichang said that the ancient Chinese totem "Qilin" has already given us inspiration - the chimera of heterogeneous organisms may be our key to the future. Kirin, as an auspicious beast that combines deer antlers, lion head, tiger eyes, elk body, and ox tail, is the perfect metaphor for "chimera of heterogeneous organisms" in modern life sciences. Scientists are trying to embed human stem cells into animal embryos to create "humanized organs" for transplantation, allowing pigs to grow kidneys or hearts that can be used by humans. At the lecture, Professor Wang Jichang also used "Zhu Bajie" and other familiar images as examples, successfully stimulating primary school students' strong interest in "xenogeneic chimeras". He shared with everyone the scientific research progress and current challenges in the cutting-edge field of cultivating human organs in animals using cutting-edge biotechnology. Professor Wang Jichang hopes that students will always maintain curiosity and awe of life and be determined to contribute on the road of scientific exploration.
