[quick news] on May 20, 2019, Chinese scientific research team developed "liquid band aid"

The Chinese research team developed "liquid band aid" Recently, the British academic journal Nature · Communication published the research results of a new type of biomaterial from the Chinese research team, which can completely stop the bleeding of the great artery injury and the heart penetrating injury in a few seconds This new material is a gel that mimics biological connective tissue and can be rapidly solidified under ultraviolet irradiation The proportion of the biological glue is close to that of collagen and glycosaminoglycan in the human connective tissue, and it can be solidified within one second after UV irradiation Hong Yi, a postdoctoral researcher at the school of basic medicine, Zhejiang University, who participated in the study, said that the biological glue could stop bleeding and "fill up leakage" in various operations, which is expected to reduce the mortality and blood product consumption caused by uncontrolled bleeding Next, the team plans to transform it into a medical device that can be used for clinical use, which may be available within 3 to 5 years In this process, it may take a long time to fully ensure the safety of materials

Tsinghua university enrollment information exchange meeting and campus open day activity, Tsinghua University announced the establishment of artificial intelligence class (referred to as "smart class"), and will recruit undergraduates from the autumn of 2019 At this year's open campus day, Yu Xiaoxiao, director of the Admissions Office of Tsinghua University, said that the establishment of the artificial intelligence class is one of the innovative measures taken by Tsinghua University in terms of personnel training this year "Smart class" will carry out secondary selection for the admitted 2019 undergraduates, and the first batch is expected to enroll 30 Yao Qizhi, the winner of Turing prize and the dean of Cross Information Research Institute of Tsinghua University, serves as the chief Professor, and keeps close cooperation with many departments such as the Department of computer science and technology and the school of software, so as to deepen students' understanding of artificial intelligence with a broad-based and cross training mode The purpose of "smart class" is to cultivate the top scientific research and innovation talents in the field of artificial intelligence, build a deep cross cooperation platform among disciplines, and further promote the cross combination of different disciplines While promoting the development of different disciplines, we should deepen our understanding of the frontier of artificial intelligence and further promote the development of artificial intelligence Http://www.xinhuanet.com/politics/2019-05/19/c_.htm scientific research instrument sharing can't "heavy and light" high-end scientific research instrument is an important tool for scientific research and technological innovation, and plays an important role Because of the high price, open sharing is an effective way to use high-end instruments With the continuous development of science and technology, and the continuous improvement of the overall scientific research level, the society's demand for sharing scientific research instruments and facilities is growing It is not only required to be available, but also expected to be well used, and expected to obtain high-level scientific research instrument experiment services In practice, it is found that users of scientific research instruments need not only experimental results, but also understand the significance behind the data, so as to promote the role of instrument operators from the past "data provider" to "problem solver" However, at present, there are still some scientific research institutions that have not fully realized this When promoting the sharing of scientific research instruments, they are still "heavy and light", and they do not fully understand the role of scientists and experimental technicians For example, the number of experimental technicians in some large-scale scientific instrument facilities is insufficient, the structure is unreasonable, and it is difficult to realize the efficient use of instruments The use and open sharing of high-end scientific research instruments are not simply "open door" From purchase, development to operation, the investment of high-end instruments and scientific devices is very huge, which is related to the realization of scientific objectives How to further strengthen the construction of "software" such as talents and drive the hardware operation of instruments more efficiently needs to explore effective solutions Http://paper.people.com.cn/rmrb/html/2019-05/20/nw.d110000remrb_-19.htm the cumulative installed capacity of China's electrochemical energy storage industry broke through the guiwa pass on the 18th, and the Zhongguancun energy storage industry technology alliance released the white paper 2019 on energy storage industry research (hereinafter referred to as the white paper) According to the white paper, by the end of 2018, the cumulative installed capacity of China's energy storage projects has reached 31.3 megawatts, accounting for 17.3% of the global market Among them, the cumulative installed capacity of the electrochemical energy storage project reached 1072.7 MW, breaking the gigawatt mark, accounting for 16.2% of the total scale of the global electrochemical energy storage market, with a year-on-year growth of 175.2% Aiming at the scale of electrochemical energy storage market that has been growing rapidly in recent years, the white paper predicts that by the end of 2019, the cumulative operation scale of electrochemical energy storage in China will reach 1.92 GW; in the end of the 13th five year plan, namely 2020, the annual growth rate will continue to exceed 70%; by 2021 In, the application of energy storage will be spread out in the whole field, the trend of large-scale production is obvious, and the cost will be reduced rationally According to the white paper, with the further promotion of power system reform, energy storage will usher in a new round of high-speed development, and the scale of electrochemical energy storage will realize two consecutive jumps, breaking through 10 GW in 2022 and approaching 20 GW in 2023 Http://news.scienceet.cn/htmlnews/2019/5/426434.shtm hands free - the US develops the harvesting tomato robot, the first artificial intelligence robot, Virgo 1, which is applied in the agricultural field, developed by root AI company of Massachusetts, USA According to the company's official website, its core feature is the application of artificial intelligence software to achieve "real-time detection of fruit maturity, soft touch extraction, 3D navigation intelligent movement" Using artificial intelligence technology, Virgo 1 can recognize the maturity of tomatoes and determine which fruits can be picked It is said that its recognition efficiency is higher than the traditional artificial recognition In the picking process, the robot can drive automatically, and the front end is equipped with sensors and cameras to act as "eyes" Two "fingers" like pliers on the mechanical arm can pick tomatoes with appropriate strength, without pinching the tomatoes or tearing the vines The fuselage of Virgo 1 is equipped with lighting equipment, so it can be picked in a large area of greenhouse shed in the daytime and at night At present, the robot has been used in greenhouses in the United States and Canada for commercial level picking trial, and it is expected to achieve a larger scale of commercial applications next year
