[quick news] research and development of gene editing technology on March 11, 2019 cannot be abandoned due to choking

The research and development of gene editing technology can't stop eating because of choking "After the occurrence of gene editing baby incident, the international academic community paid great attention to it The United States Academy of Sciences, the Royal Society of England and other units jointly launched a big discussion on the incident, and invited the Chinese Academy of Sciences to participate The international scientific community formed a consensus on some issues." Nine Bai Chunli, deputy to the National People's Congress, President of the Chinese Academy of Sciences and Secretary of the Party group, said Sunday that the consensus includes: at present, before the technology is immature and the corresponding social ethical issues are not fully discussed and solved, we should prohibit the clinical trial and application of human reproductive gene editing; while for basic research, scientists can be allowed to try to explore, otherwise it will affect The pace of technological innovation Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-03/11/content_.htm? Div = - 1 the jiangpeng group of Tsinghua University revealed that cancer cells regulate ammonia metabolism through p53 In a new study, the jiangpeng group of the school of life of Tsinghua University in China reported that as the most frequently mutated tumor suppressor gene in human tumors, p53 It regulates ammonia metabolism by inhibiting urea cycle By downregulating the transcription of CPS1, OTC and arg1, p53 can inhibit urea production and ammonia clearance in vitro and in vivo, thus inhibiting tumor growth In turn, the down-regulation of these genes activates p53 through the mechanism mediated by MDM2 The results were published online in the journal Nature recently Https://www.nature.com/articles/s41586-019-0996-7 in the next ten years or so, Chinese people will set foot on the moon March 10 Wu Weiren, member of the National Committee of the Chinese people's Political Consultative Conference and chief designer of the lunar exploration project, said in a speech at the Third Plenary Session of the second session of the 13th CPPCC National Committee that China will become one of the world's space powers with the implementation of landmark projects such as the first Mars probe launched next year after chang'e-5 returned from the moon this year In the next decade or so, there will be a lunar research station dominated by China and participated by many countries in the south pole of the moon The footprints of Chinese people will step on the moon, and China will step into the forefront of the world's aerospace power Http://www.chinanews.com/shipin/cns-d/2019/03-10/news806916.shtml research has found that intestinal flora plays an important role in thermoregulation Congratulations on having survived another cold winter Is the biggest contributor to your winter survival a thick down jacket or a "swimming circle" on your stomach? A new study by the Institute of genetics and developmental biology of the Chinese Academy of Sciences may overturn your cognition The John Speakman team, a researcher at the Institute, found that intestinal flora plays an important role in thermoregulation of animals in cold conditions The results were recently published in cell communication This study enhanced the understanding of physiological and health significance of intestinal microorganisms The researchers pointed out that although the research was carried out in mouse model, it should be treated with caution whether it has reference significance for human beings, but it still has important implications for human health research Https://www.cell.com/cell-reports/fulltext/s2211-1247 (19) 30177-9? 65123; returnurl = HTTPS% 3A% 2F% 2flinkinghub.elsevier.com% 2ffretrieve% 2fpii% 2fs2211124719301779% 3fshowall% 3dtrue how to make drugs "kill enemies" more accurately? The latest research results of the cooperation between Gan Yong research team of Shanghai Institute of medicine, Chinese Academy of Sciences and Shi Xinghua team of national nano center provide new perspectives and new ideas for rational design of liposomes as drug delivery system The paper was published in the proceedings of the American Academy of Sciences The results show that the composition of phospholipids determines the phase transition temperature of the "chariot" liposome, and the higher the phase transition temperature is, the greater the rigidity of the liposome is Researchers have found that liposomes with different phase transition temperatures will produce different deformations in the diffusion process Based on this result, the research team prepared liposomes suitable for the temperature of the human body to avoid physiological barrier interception The research shows that "Warriors" have successfully arrived at the "enemy camp" with good achievements, good drug absorption and significant improvement in relative bioavailability https://www.pnas.org/content/early/2019/03/04/1818924116
