Experimental samples such as nematodes, regenerated rice, and alloy materials were successfully returned from the Chinese space station and delivered to the experimental scientist space

Release time:Apr 13, 2024 20:26 PM

On the morning of June 4, 2023, the fourth batch of space science experimental samples from the Chinese space station returned to the ground with the return capsule of the Shenzhou-15 spacecraft, and the space application system led by the Chinese Academy of Sciences was delivered at the Dongfeng landing site.

At about 14:00 on the 4th, some experimental samples were transported to the Space Application Engineering and Technology Center of the Chinese Academy of Sciences in Beijing. The overall space application system and relevant experimental personnel checked and confirmed the basic status of returned experimental samples, and handed over to relevant experimental scientists for follow-up research.

The space application system, accompanied by the return module of the Shenzhou-15 spacecraft, carried out a total of 15 scientific project experimental samples, including life experiment samples such as cells, nematodes, Arabidopsis, and regenerated rice, as well as various alloy materials, new infrared detector materials, amorphous thin film materials, and other material experimental samples. The total weight of the downward experimental sample is over 20 kilograms.

Subsequent scientists will conduct molecular biology, cell biology, in orbit growth, development, and metabolism analysis on returned life samples. Through comparative analysis with the ground, the laws and molecular mechanisms of the effects of space microgravity and radiation on experimental samples will be analyzed, providing a theoretical basis for the further creation of crops adapted to the space environment and the development and utilization of space microgravity, radiation, and other resources. The material experimental samples will be tested and analyzed in the laboratory to reveal the laws of material physical properties and chemical changes that are difficult to obtain in the ground gravity environment, obtain key conditions for high-performance preparation technology, and guide the preparation of new ground materials.

Recently, with the approval of the National Medical Products Administration, the Class 1 innovative drug CC312 developed by Huihe Biotechnology has initiated phase I clinical trials for the treatment of recurrent/refractory CD19 positive B-cell malignant hematological tumors. This is the first domestically and the third globally approved triple specific antibody drug based on CD28 co stimulatory signals to enter clinical practice. When it comes to the development history of this new triple antibody drug, Dr. Zhu Huaxing, the founder of Huihe Biotechnology, still remembers vividly: "Before 2019, there was no triple antibody drug approved for clinical use globally, and some investors couldn't understand CC312. During a critical period of company development, Nokai Xinkang Fund invested 30 million yuan to help us complete Series A financing." Nokai Xinkang is a venture capital fund initiated by Xinze Entrepreneurship Incubator. This incubation company, which has been deeply cultivated in Zhangjiang Science City for many years

Not only can you hear Beethoven talk freely in "Moonlight", but you can also achieve precise positioning in three-dimensional scenes, and complete scene analysis through the combination of images and sound. On June 16, at the AI Framework Ecological Summit, the Institute of Automation of the Chinese Academy of Sciences officially released the full mode large model of "Zidong Taichu". This model is the 2.0 version upgraded from the 1.0 version of the 100 billion parameter multimodal model "Zidong Taichu". On the basis of voice, image and text three modes, it adds video, sensor signal, 3D point cloud and other modal data, breaks through the key technologies such as multimodal correlation for cognitive enhancement, and has full modal understanding, generation and correlation capabilities. At the meeting, Xu Bo, the director of the Institute of Automation, presented for the first time in real time the "Zidong Taichu" full modal cognitive model in music understanding

"The college entrance examination is an experience in our lives. Looking back on the preparation for the entire senior year of high school, we cannot help but marvel at the preciousness of time. No matter what difficulties we have gone through, I believe that as long as we persist, it will become my lifelong wealth. Today, after completing the morning foreign language listening and speaking test of the college entrance examination, Xiao Song, a senior student of Lingling High School, came out of the examination center of East China University of Science and Technology Affiliated Middle School. The senior year graduate sitting in a wheelchair said," Although academic and life are not small tests for me, I have faced many difficulties in adversity and have never given up on my dream of taking the college entrance examination. "Xiao Song suffered from congenital muscular dystrophy since childhood and entered Lingling High School in high school." Later, the school provided him with classrooms on low floors and close to the toilet, making it easier for him to enter and exit, allowing him to face his academic life with more confidence. At school, I met many kind and enthusiastic people
