[quick news] July 23, 2019, Chinese version of "Jueming poison master": Associate Professor of College of chemical engineering opens a company to make poison

Zhang ZHENGBO, associate professor, School of chemistry and chemical engineering, Huazhong University of science and technology In 2005, he established Wuhan Kaimen Chemical Co., Ltd in cooperation with others, specializing in the research, development, production and customization of chemical intermediates for various pharmaceutical and industrial purposes On June 17, 2015, Wuhan Customs and police found a batch of manufacturing equipment, toluene, ether, hydrochloric acid and other precursor chemicals, as well as a large number of powder and crystal like drug suspects from Kaimen chemical's factory Soon, Zhang ZHENGBO and Yang, the legal representative of Kaimen chemical, were arrested on suspicion of drug smuggling On the day before world drug day 2019, the case of Zhang ZHENGBO, known as the Chinese version of "Jueming drug master", was retrialed and sentenced The Wuhan intermediate court found that Zhang ZHENGBO committed the crime of smuggling, trafficking, transporting and manufacturing drugs, with the circumstances of surrendering himself, and changed the original life sentence to 15 years' imprisonment Http://www.chinanews.com/sh/2019/07-23/8903741.shtml Australia Research: the impact of coffee drinking on human health has been widely debated Coffee drinking is not associated with cancer, according to a new study in Australia Daily coffee consumption does not increase or reduce the risk of cancer The study looked at some common cancer types, such as breast, ovarian, lung and prostate cancers, and found that coffee consumption was not associated with the incidence rate of these cancers But there are some uncertainties in the study of colorectal cancer, and the researchers believe that more research is needed to determine the relationship between colorectal cancer and coffee The biological active components of coffee include caffeine, caffeinol and other substances Previous animal experiments have proved that these substances have anti-tumor effect, but the anti-cancer effect of coffee on human body has not been clear Http://www.xinhuanet.com/science/2019-07/22/c_.htm a new research team in the UK has reported that they can better analyze the oncogenes of esophageal cancer with the aid of artificial intelligence, and based on these new findings, it is expected to improve the diagnosis and treatment efficiency of this type of cancer in the future The team used the artificial intelligence technology to analyze the genes of 261 patients with esophageal cancer, and found 952 new related genes Based on the different characteristics of these genes, the researchers divide patients into six categories, and in the future, different treatment schemes can be adopted for different types of esophageal cancer Compared with monotherapy, individualized treatment may achieve better results The team hopes to use this method to further analyze the characteristics of early stage of esophageal cancer, find the genetic source driving the occurrence of this disease, so as to realize early diagnosis and personalized treatment in the future Https://www.nature.com/articles/s41467-019-10898-3 silicon nanoparticles help to "expose" tumor agglomeration area, Moscow Institute of Engineering Physics, Russian National Nuclear Research University and other domestic and foreign scientific research institutions to develop a new method of optical diagnosis of cancer with silicon nanoparticles It is very effective to irradiate silicon nanoparticles with light or ultrasound in the treatment of local overheating (fever) and destruction of cancer cells, but in biological tissues, it is difficult to show the best size of silicon nanoparticles optically, because they have no fluorescence ability The research team found a solution to the problem of "visual inspection" of large silicon nanoparticles in biological tissues Because this kind of nanoparticles may have strong nonlinear reaction under optical stimulation This method has a very high optical resolution, which is helpful to restore the 3D image of the distribution of silicon nanoparticles in cells and tissues Http://sputniknews.cn/science/201907171029028614/ NASA Tries to plant chili peppers on the international space station The United States intends to land humans on Mars in the 1930s In response to the lack of nutrition in astronauts' future deep space journey, NASA ）Efforts are being made to plant various plants in space, with the current target of Capsicum If all goes well, capsicum will be the first plant to grow and bear fruit on the international space station There are still many challenges for scientists to plant crops in space, after NASA has planted lettuce, cabbage, mustard and so on And space plants must meet two conditions, one is easy to pollinate, the other is able to survive in a high concentration of carbon dioxide environment, pepper just has these characteristics http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-07/23/content_426239.htm?div=-1
