Alveolar development puzzle opened
BEIJING, February 21 (Reporter Zhao Yongxin) The recently published international academic journal Developmental Cell published a research paper by Tang Nan Laboratory of Beijing Institute of Life Sciences in the form of a cover article, and the study was first adopted in the world In vivo imaging technique is used to observe the development of alveoli visually and in real time. A new model of alveolar growth controlled by mechanical force and growth factor is proposed.
Alveolar development process is very complex, Tang Nan laboratory after more than three years of continuous efforts, the successful realization of in vivo and in vitro fetal lung fetal live and dynamic imaging, and after 8-10 hours of continuous experiments to complete the Real-time observation of alveolar development.
Industry colleagues believe that the important findings of Tang Nan Laboratory not only provide new ideas for the study of proliferation and differentiation of many stem cells in vivo, but also provide important references for the prevention and treatment of related diseases such as hypoplasia.
Depression research has been a major breakthrough
Hangzhou, February 21 (Jiangnan, Zhou Wei) On the occasion of the Spring Festival, good news came from China's medical science research field and Hu Hailan team from Zhejiang University made a major breakthrough in depression research. On February 15, "Nature" Magazine published two long articles by the team over the same period, revealing the mechanism of action of rapid antidepressants, advancing their understanding of the pathogenesis of depression and providing several new molecular targets for the development of novel antidepressants.
In modern society, depression has become one of the most serious mental diseases affecting human life, the global incidence rate of 11% .The study found that the special part of the brain discharge patterns and depression, the relationship revealed the first time the lateral habenular nucleus Special discharge mode - cluster discharge, is a sufficient condition for the occurrence of depression.
Reviewers of Nature magazine highly appraised this series of major breakthroughs, and Nature and another top-level journal, Science, distributed commentaries on these two tasks.
Quantum chip development has made new progress
According to Xinhua News Agency, Hefei, February 21 (Reporter Xu Haitao) This reporter learned from the University of Science and Technology of China: Recently, the team of Academician Guo Guangcan made new progress in the development of semiconductor quantum chips. For the first time in the world, the three qubits in the semiconductor system Logic gate manipulation, for the future development of scalable, semiconductor semiconductor quantum chips can take a solid step forward.Is the authoritative international journal of Applied Physics, "Review of Physics Applications" recently published the results.
The development of semiconductor fully-controlled quantum chips that is compatible with modern semiconductor processes is one of the most important directions for the development of quantum computers currently.The team succeeded in achieving the world's first three-charge quantum bit logic based on semiconductor quantum dot system through theoretical calculation and analysis Doors further enhance the efficiency of quantum computing.
Reviewers of "Physical Reviewing Applications" think that this work is an important progress in the quantum computing of quantum dots in semiconductors, which will arouse academic enthusiasm in this field.
