[quick news] on January 22, 2019, Guangdong preliminarily identified the "gene editing baby event"

Guangdong initially identified the "gene editing baby event" according to the introduction of the "gene editing baby event" investigation team of Guangdong Province, June 2016 He Jiankui, associate professor of South University of science and technology, started to organize a project team including overseas personnel to evade supervision deliberately, use technologies with uncertain safety and effectiveness, and carry out human embryo gene editing activities for reproductive purposes that are expressly prohibited by the state From March 2017 to November 2018, he Jiankui recruited 8 couple volunteers (HIV antibody male positive, female negative) to participate in the experiment through other people's forged ethical review In order to avoid the relevant regulations that AIDS carriers are not allowed to implement assisted reproduction, they plan to take the place of volunteers for blood test, and instruct individual employees to edit genes on human embryos and implant them into the mother in violation of regulations Finally, two volunteers are pregnant, one of them has given birth to twin baby girls "Lulu" and "Nana", the other is pregnant One of the other six pairs of volunteers dropped out of the experiment and the other five were not pregnant This behavior seriously violates the ethics and the integrity of scientific research, seriously violates the relevant provisions of the state, and has a bad impact at home and abroad The head of the investigation team said that he Jiankui and the personnel and institutions involved will be dealt with seriously according to the law and regulations, and those suspected of crimes will be transferred to the public security organ for handling Guangdong Province will, under the guidance of the relevant departments of the state, make medical observation and follow-up work together with relevant departments for the born babies and pregnant volunteers Http:// new brain imaging technology can quickly generate ultra-high resolution 3D images Researchers from Massachusetts Institute of technology, University of California, Berkeley, Howard Hughes Institute of medicine and Harvard Medical School have developed a new brain imaging technology, which can quickly image the brain in three dimensions with higher resolution and reveal the connection of the whole brain neurons faster than other methods The key of the new technology is to combine the extended microscope technology with the grating light microscope technology By expanding the volume of the observed tissue, the extended microscope technology can significantly improve the imaging resolution Combined with the grid light microscope, which is a rapid three-dimensional microscope technology, it can generate ultra-high-resolution three-dimensional images of the observed tissue faster Http://science.sciencemag.org/content/363/6424/eaau8302 researchers recently used nanoscale hydrogel 3D to print artificial ears Recently, researchers made use of biodegradable wood nanofibers and made artificial ears through 3D printing technology They can be used as implants for congenital deformity of children's ears The researchers explored the characteristics of nano cellulose hydrogel, and further optimized its stability and 3D printing process, and made artificial ears which can be used for transplantation This kind of artificial ear can reconstruct the auricle for children with congenital auricle deformity, which can remedy the deformity of the ear without affecting the hearing In addition, hydrogels containing nanofibers can also be used as knee implants to repair joint wear caused by chronic arthritis Https:// will provide Wal mart with self driving trucks as part of a pilot project to provide fresh food for Wal Mart (WMT) U.S California startup udelv recently announced that it will deploy self driving trucks in surprise, Arizona, using Baidu technology Baidu has always been very optimistic about artificial intelligence and hopes to become an industry leader Last year, it became the first Chinese company to join the U.S - led AI alliance, which includes a number of Silicon Valley bigwigs, such as Facebook, Google, Amazon and Microsoft Https:// construction of evaluation system of medical and health journals is imminent At the launching ceremony of the "peak forum on the construction of evaluation system of medical and health journals" held recently, many experts and scholars from the field of medical and health and medical journal industry proposed that it is an urgent task to establish an evaluation system of academic journals widely recognized by the Chinese academic community Han Qide, academician of the Chinese Academy of Sciences, said that in 2018, there were more than 1200 kinds of Chinese medical and health academic journals, and in 2017, only clinical medicine published 130000 papers, ranking first Zhang Daqing, director of the medical library of Peking University, thinks that China's scientific research is now at the forefront of the world, but how to improve the quality of scientific research, especially how medical and health journals reflect the level of science and technology, needs further discussion http://digitalpaper.stdaily.com/http_
