"Molecular food" for Mid Autumn Festival? In fact, the marshmallow you ate when you were a child is the mid autumn festival that your friends are thinking about In addition to family reunion, tea tasting and moon watching, the rest of the traditional Chinese festival is a feast The term molecular gastronomy was not coined by a chef, but by Hungarian physicist Nicholas Kurti and French chemist Herve this in 1988 In 1969, Nicholas Kuti, a professor at Oxford University, began to study food from a scientific point of view He proposed that pineapple juice containing enzymes can make meat softer, and the principle of slow cooking at low temperature Molecular food is not tall, it is around us, such as marshmallow, tofu, eggs, jelly, milk powder, etc Http://digitalpaper.stdaily.com/http_ Div = - 1 which is the best university chemistry discipline in mainland China? From the perspective of the whole country, there are 69 universities with the first level doctor's degree in chemistry discipline Combined with the fourth round of the first-class discipline evaluation of the Ministry of education, there are 15 colleges and universities that have obtained "a -" or above in the first-class discipline of chemistry nationwide Among them, except Fuzhou University, the other 14 are "double first-class" construction universities The 15 universities are Peking University, Tsinghua University, Fudan University, Shanghai Jiaotong University, Nankai University, China University of science and technology, Xiamen University, Fuzhou University, Jilin University, Zhejiang University, Nanjing University, Wuhan University, Hunan University, Zhongshan University and Sichuan University Http://news.scienceet.cn/htmlnews/2019/9/430434.shtm is the first to find that ion exchange can be carried out in semiconductor plastics (polymer semiconductor) by Tokyo University Ion exchange is widely used in water purification, protein separation and purification, industrial sewage treatment and so on It is an indispensable chemical phenomenon in life This study found an innovative principle, that is, using this very common ion exchange, we can control the electronic state of semiconductor plastics Using this principle, the research team precisely controlled the electronic state of semiconductor plastics and successfully realized the plastics with metal properties Http://digitalpaper.stdaily.com/http_ Div = - 1 "zero tolerance" attitude to investigate and deal with scientific research dishonesty cases In recent years, our country attaches great importance to the construction of scientific research integrity, from the aspects of policies and regulations, system construction, education and training, information construction and other aspects, strengthen the supervision and management of scientific research behavior, and constantly build a fresh and positive scientific research atmosphere and environment At the level of laws and regulations, the law of the people's Republic of China on the progress of science and technology, which was implemented in 2007, stipulates that scientific research should "carry forward the scientific spirit, abide by scientific norms, abide by professional ethics, be honest and trustworthy", and clarify the punishment measures for acts violating the requirements of scientific research integrity Nowadays, the working mechanism of scientific research integrity is more and more smooth The Ministry of science and technology and the Chinese Academy of social sciences are respectively responsible for the construction of scientific research integrity in the fields of natural science, philosophy and social sciences Http://news.gmw.cn/2019-09/12/content_.htm it's cold The intestinal flora helps you keep warm in the winter of Xilingol prairie in Inner Mongolia It's dry, cold and windy The average temperature can reach minus 20 ℃, and the extreme low temperature can reach minus 42 ℃ Many animals will choose to hibernate to spend such a winter But a small rodent, Brandt's vole, which only has a palm, not only refuses to hibernate, but also develops a series of physiological mechanisms against low temperature Wang Dehua research group, Institute of zoology, Chinese Academy of Sciences, has been exploring the physiological adaptation mechanism of Brandt's vole for many years Recently, they found that the small animals not only rely on burrowing and fattening to fight against the cold, but also the gut microbes in their stomachs Recently, a paper published in the Journal of the ISME journal revealed the role of intestinal flora in thermoregulation and metabolic thermogenesis of Microtus Brandt http://news.sciencenet.cn/htmlnews/2019/9/430429.shtm
