[quick news] December 6, 2019 NAT Chem: new optical materials can be used to kill cancer

Nat Chem: new optical materials can be used to kill cancer Materials scientists at the University of California Riverside and the University of Texas Austin have proved that the use of silicon nanocrystals and specially designed structures of organic molecules can achieve light energy higher than that of excitation materials The results, published in nature chemistry, bring scientists a step closer to developing minimally invasive photodynamic therapy for cancer This progress may also lead to new technologies for solar energy conversion, quantum information and near-infrared driven photocatalysis Http://news.bioon.com/article/6747446.html the new method reveals the atomic arrangement of graphene superconductive materials A research group composed of Tokyo University, Waseda University, Japan Atomic Energy Research and development agency, high energy accelerator research agency, etc uses "total reflection high speed positron diffraction" (trhepd For the first time, the atomic arrangement of the two-dimensional compound with superconductive properties formed by graphene and calcium was determined In addition, the research team confirmed through experiments that the atomic arrangement shows the phenomenon of superconductivity with zero resistance, which opens the way for the development of ultra-high speed information processing nano devices with zero energy consumption using graphene Relevant research papers have been published in the academic journal carbon online recently Http://digitalpaper.stdaily.com/http_ Div = - 1 the inextricable chain of industrialization and application of material genetic engineering "The next few years will be a critical period for the transformation, upgrading and high-quality development of China's manufacturing industry The construction of a manufacturing power provides a broad market space for the new material industry, and also puts forward higher requirements for the speed, cost, quality and performance of new material research and development." Chang Guowu, deputy director of the Department of raw materials of the Ministry of industry and information technology, suggested that in order to develop material genetic engineering in China, it is necessary to further accelerate the connection between industrialization and application of new material research and development, make full use of the national new material testing and evaluation platform, new material production and application demonstration platform and new material resource sharing platform, promote the sharing of data and information facilities, and further create good talents Growth environment, accelerate the cultivation of a number of international composite talents Http://digitalpaper.stdaily.com/http_ / 05 / content_ HTM? Div = - 1 human immune system evolution has "side effects" Human immune system has been evolving, which can help us better resist some diseases, but there are also some "side effects" Changes in DNA fragments associated with the evolution of the immune system may make people more susceptible to certain autoimmune diseases, a new study suggests Researchers from the University of Nijmegen in the Netherlands published a paper in the new issue of immunology trend, saying that they investigated relevant data in the fields of genetics, immunology, microbiology and virology, and analyzed how the DNA related to infectious pathogens in the genome of some populations in Africa and Eurasia changed in the evolution process Although these changes make people not easy to be infected by some pathogens, they may be related to Crohn's disease, lupus erythematosus and other self inflammatory diseases Autoimmune diseases are recurrent or persistent inflammatory diseases caused by inherent immune system defects or disorders Http://digitalpaper.stdaily.com/http_ / 05 / content_ HTM? Div = - 1 under the new mode of knowledge production, the unreasonable factors of discipline institutionalization must be transformed to facilitate the development of science and the rational play of knowledge efficiency Establish the concept of "from inside to outside" discipline institutionalization construction Weaken the boundary of disciplines and strengthen the division and cooperation of academic work Break down the original institutional barriers and innovate the development of disciplines Since the development of discipline system, many forces have gradually formed a circle of power and interest In recent years, in terms of scientific research evaluation, talent recruitment, academic production and discipline development, the State Administration has increased reform efforts With the introduction of new policies and new ideas, the development of disciplines will usher in new opportunities http://paper.jyb.cn/zgjyb/html/2019-12/05/content_573686.htm?div=-1
