[quick news] on November 28, 2018, the list of "highly cited scientists" of Kerui Wei'an was published

In 2018, the "highly cited scientists" list of Kerui Weian was published based on web of science data Through the analysis of citation data in the past 11 years, Kerui Weian released the fifth "highly cited scientists" list, and selected the most highly cited papers in various fields, that is, the most influential researchers recognized by the global peers The number of "highly cited scientists" in the United States is far ahead, reaching 2639; that in the United Kingdom is 546 China continues to grow strongly: the number of "highly cited scientists" in mainland China alone has reached 482, more than double that of last year, second only to the United States and the United Kingdom; 51 in Hong Kong, 5 in Macao and 20 in Taiwan Among the scientific research institutions, Harvard University still ranks first in the number of "highly cited scientists" Https://hcr.clarivate.com/ two generations of supramolecular "transnational marriage" to prevent and treat Alzheimer's disease a few days ago, Professor Guo Dongsheng's research group of Nankai University and Professor Bart Jan ravoo of the University of Minster, Germany, cooperated to make the two generations of protein supramolecular (cyclodextrin and calixarene) "transnational marriage", and obtained a new kind of CO assembly body The results of cell experiments show that the coassembly has the ability of nanomolar binding to Alzheimer's disease-related proteins, and shows good selectivity It can not only inhibit the fibrosis of Alzheimer's disease-related proteins, but also significantly reduce the cytotoxicity of amyloid protein, dissolve the already fibrotic amyloid protein, and has wide application in the prevention and treatment of Alzheimer's disease Jing This research result is published in the latest issue of nature chemistry Https:// scientists uncover the chimerism barrier of primate pluripotent stem cells On November 27, Li Tianqing team of primate Transformation Research Institute of Kunming University of technology published a paper on cell reports, revealing the chimerism barrier of primate pluripotent stem cells and the mechanism of embryo and stem cell action It was found that when pspcs were injected into early embryos, the injected stem cells were quickly removed from the embryos within 24 hours because of apoptosis In order to inhibit apoptosis, researchers selected a new culture medium suitable for both stem cell survival and embryonic development, and then put the injected embryos in this culture medium The expression of apoptosis gene of stem cells was significantly inhibited, and the survival rate of stem cells in monkey embryos was significantly improved They not only increased the efficiency of embryo chimerism of pspcs from 0% to 59.8%, but also got the full-term chimeric monkeys This study not only provides a method to understand the pluripotency of primate stem cells, but also lays an important foundation for the research of basic developmental biology and regenerative medicine of stem cells Https:// (18) 31730-3 ා AI can recognize the real age through the periocular skin in the photo researchers have published a new artificial intelligence system, which can predict the age of a person by simply "looking" at a face photo In this paper, more than 8000 photos are used to test the artificial intelligence technology of age prediction The results show that the system can predict the correct age with an average absolute error of 2.3 years The study found that the skin near the corner of the eye and the eyelid was the most exposed to the real age The researchers say the technology could be used to personalize treatments against aging Https:// the UK government released a climate forecast report on November 26th the UK government released a climate forecast report saying that if global greenhouse gas emissions remain high, by 2070, the UK's summer temperature is expected to rise by 5.4 The temperature rise in winter will reach 4.2 ℃ The report, UK climate forecast 2018, was completed by the Hadley Centre for climate prediction and research of the Met Office and other agencies, assessing the likely climate change in the UK by 2100 If global greenhouse gas emissions remain high, by 2070, not only will Britain's temperature rise in summer and winter, but its average rainfall in summer will decrease by 47% and winter rainfall by 35%, the report said http://
