    Russian scientists obtained cancer killing compound from sponge biological pigment Chemists from the school of natural science, far east Federal University of Russia developed a new synthesis method of Fascaplysin derivative pigment on the basis of sponge derivative For the first time, scholars have obtained enough compounds for research The University points out that the substance may be used for selective treatment of malignant tumors and will not have adverse effects on healthy cells As for the development of new drugs, it's still too early, said Maxim zedkov, associate professor of the teaching and research section of organic chemistry at the school of natural science, far east Federal University Based on the results obtained, the researchers plan to synthesize a series of new Fascaplysin derivatives and test them in mice Http://sputniknews.cn/russia/201911131030036485/ Professor Yao Hongbin, Professor Ni Yong and Professor Yu Shuhong of University of science and technology of China and their research team were inspired by the high toughness of pearl layer, and proposed a method to strengthen the impact toughness of polyolefin membrane By constructing a pearl like coating on the surface of the polyethylene membrane, the team effectively maintained the pore structure of the membrane after impact, thus ensuring the uniform lithium ion flow during the battery charging and discharging process Compared with the soft battery with the commercial ceramic membrane, the soft battery with the Pearl like membrane exhibits less open circuit voltage change, better cycle stability and high safety during the impact The research results were recently published online in advanced materials Http://www.chinanews.com/gn/2019/11-13/9006226.shtml notice of the general office of the Ministry of science and technology, the general office of the Ministry of finance, the general office of the Ministry of education, the general office of the Chinese Academy of Sciences on the implementation of the seven actions to reduce the burden of scientific research personnel In June, the Ministry of science and technology, the Ministry of finance, the Ministry of education and the Chinese Academy of Sciences jointly issued the special action plan for reducing the burden of scientific research personnel (gkfz [2018] No 295, referred to as the action plan) to implement the spirit of the important speech made by the general secretary of internship at the academician conference of the two academies, and carried out 7 actions to reduce the burden of scientific research personnel nationwide, achieving positive results In order to ensure the continuous and in-depth promotion of the action, achieve the expected effect, and form a long-term mechanism for reducing the burden of scientific researchers, we hereby entrust the science and technology evaluation center of the Ministry of science and technology, the science and technology development center of the Ministry of education, and the management innovation and evaluation research center of the Chinese Academy of Sciences to jointly organize the third-party evaluation of the implementation of the action Http://www.most.gov.cn/mostinfo/xinxifenlei/fgzc/gfxwj/gfxwj2019/201911/t20191113_.htm sodium titanate holding graphene to create high-energy, high-power micro capacitors The team of Wu Zhongshuai, researcher of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, worked with Bao Xin and academician team to combine "sea urchin" and graphene to develop a flexible sodium ion micro super capacitor with high energy density and high heat resistance According to the R & D personnel, the sodium ion micro super capacitor has a multi-directional rapid ion diffusion channel, which greatly reduces the charge transfer resistance and significantly improves the power density At the same time, due to the planar geometry of the device and the non flammability of the ionic gel electrolyte, the micro device has good mechanical flexibility and high temperature stability at 80 degrees Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-11/14/content_ HTM? Div = - 1 Zhejiang University creates a new model of youth science popularization and education "Young scientists and their friends", a high-end popular science course launched by the Youth League Committee of Zhejiang University, is mainly composed of young Changjiang Scholars from the Ministry of education, young top talents from the Central Organization Department, winners of the National Science Foundation for outstanding young scholars, and young 973 chief scientists from the Ministry of science and technology Yang Min, chief scientist of national 973 program and professor of Fudan University, and Zhang Huiping, a researcher of State Key Laboratory of earthquake dynamics of Institute of geology, China Seismological Bureau, have been invited as keynote speakers for four sessions of science popularization courses They have conducted in-depth discussions with young people of Zhejiang University on topics such as mobile security and Qinghai Tibet Plateau While teaching knowledge, they also share their mental journey, so that young students can experience the demeanor of young scholars in a close and intuitive way http://zqb.cyol.com/html/2019-11/14/nw.D110000zgqnb_20191114_2-02.htm
