[quick news] the world's first UAV use standard announced on November 30, 2018

The world's first standard for the use of drones announced that the use of drones is increasing, but the rules and regulations of different jurisdictions are different Therefore, the international organization for Standardization (ISO) has issued the first draft of the global standard for the use of UAVs The draft recommends the establishment of no fly zones around airports and other restricted areas, and the adoption of ground protocol measures to keep UAVs away from sensitive locations The standard also requires UAV operators to respect the privacy of others and provide manual intervention failure insurance for all flights ISO also recommends that training, flight records and maintenance requirements, as well as data protection rules, be in place More UAV usage standards covering technical specifications, traffic control and manufacturing quality will be released immediately, and ISO hopes that they will become the best solution for global UAV usage rules

China Association for science and technology responded to the event of "gene editing baby", the event of "gene editing baby" was announced, which attracted wide attention of the academic community and the society, especially caused legal and ethical disputes Leaders of the National Health Commission, the Ministry of science and technology, and the China Association for science and technology responded to the incident Thursday The national health and Health Commission said: scientific research and medical activities must be carried out in accordance with relevant laws, regulations and ethical standards, and violations of laws and regulations must be resolutely investigated and punished Ministry of science and technology: the relevant units have been required to suspend the scientific research activities of the relevant personnel, and will investigate and deal with the relevant departments according to laws and regulations on the basis of a comprehensive and objective investigation of the truth of the incident China Association for science and technology said: it will further strengthen the education of scientific research ethics for the scientific and technological community, and cancel he Jiankui's qualification for the 15th "China Youth Science and Technology Award" Http://www.xinhuanet.com/2018-11/29/c_.htm research shows that dogs may not be as smart as people think, according to the daily mail, a new study found that dogs are not as smart as many people think Psychologists from the University of Exeter in the UK and the University of Canterbury in New Zealand compared the cognitive abilities of dogs with other animals They concluded that canines are no more intelligent than other species and are not particularly good at understanding the objects around them In addition, pigs perform just as well as dogs in odor recognition tests of humans

The international top academic journal Nature published online the research results of Xu Chenqi, the National Key Laboratory of molecular biology, Institute of Biochemistry and cell biology, Chinese Academy of Sciences The team found that there was a rapid degradation process of PD-1 in normal T cells, in which the protein fbxo38 played a key role Fbxo38 can label PD-1 with a kind of mediated degradation tag PD-1 with degradation tag will be sent to proteasome for degradation, so as to ensure that PD-1 maintains normal level and does not affect the function of T cells However, in the T cells surrounded by tumor, fbxo38 is too active, which may lead to PD-1 can not be degraded normally Therefore, T cells are "trapped" in PD-1, and the anti-tumor immune response is inhibited The research results reveal the degradation mechanism of PD-1 in human immune system and its function in tumor immune response for the first time Https://www.nature.com/articles/s41586-018-0756-0 new drugs help AIDS patients get rid of the shadow of death On December 1, World AIDS Day will usher in its 30th anniversary, and nearly 40 years have passed since the first AIDS patient was found To help AIDS patients get rid of the shadow of death, it is the continuous upgrading of drugs More than 20 years ago, the emergence of cocktail therapy, let AIDS patients live longer In 2006, the emergence of a single drug for AIDS once again changed the situation that AIDS patients must take more than ten drugs a day Recently, Johnson & Johnson has released two new anti AIDS drugs, ENRIN and puzeli, in Xi'an Janssen Pharmaceutical Co., Ltd., a Chinese pharmaceutical subsidiary These two drugs should be used in combination with other anti HIV drugs for the treatment of adult type 1 human immunodeficiency virus (HIV-1) infection The dosage is one tablet per day, which is easier to use, helps to reduce the burden of taking medicine for AIDS patients, and improves compliance
