Science Popularization: who emphasizes that simple 5 steps can help prevent influenza Who introduces it on its website Simple 5 steps can help prevent influenza to the greatest extent The most effective and key preventive measure is to vaccinate against influenza In addition to the barrier of vaccination, who said that the four steps of washing hands frequently, avoiding touching your eyes and nose, staying away from flu patients and staying at home if you feel uncomfortable are also very effective for the prevention of influenza Http://www.xinhuanet.com/2019-12/28/c_.htm Nanyi University: genetic code to solve the "risk of lung cancer" of Chinese people, academician of Chinese Academy of engineering and Professor Shen Hongbing of Nanjing Medical University, said: "lung cancer is a complex disease, which is the result of the joint action of environmental factors and genetic factors." At present, his research team through the whole genome association study (GWAS), found 19 Chinese lung cancer susceptibility genes, and constructed the multi gene genetic risk scoring index of Chinese lung cancer, which can achieve prospective prevention According to researchers from the school of public health, Nanjing Medical University, now only blood, hair, oral mucosa and other genotypes can be taken for testing, so that the subjects can know whether they are prone to cancer (risk) We can customize a gene chip for detection according to the detected loci to see if we have these susceptible genotypes Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-12 / 30 / content_ HTM? Div = - 1 Professor Song Chuankui, National Key Laboratory of tea plant biology and resource utilization, Anhui Agricultural University, first found that fragrance can also effectively regulate the cold resistance of plants Increasing the accumulation of some aroma substances in plants can improve the cold resistance of plants, whereas the cold resistance of plants is significantly reduced This study not only provides a theoretical basis for the regulation of neropentol glycosides in tea plants, but also provides a new idea for the study of plant cold resistance Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-12 / 30 / content_ HTM? Div = - 1 Chinese chemical research: Reshaping chemical endogenous dynamics in transformation At the moment of chemical discipline transformation, Chinese chemical researchers have made outstanding achievements in the intersection of chemistry and physics, and the intersection of various secondary disciplines of chemistry, which has explored a new way to reshape the endogenous dynamics of chemistry "In the future, we should attach importance to giving" new connotation "to the" old system ", and lay out and study new directions such as organic topological insulator, organic thermoelectricity and organic superconductivity, so as to promote the formation and development of organic electronic industry." Zhu Daoben pointed out that "in the 21st century, chemistry will present a trend of diversification and highly cross development Chinese scholars should fully grasp the opportunity of independent innovation in the field of molecular electronics and inject new development impetus into chemical science."
