[quick news] Chinese scientists successfully cloned hybrid rice seeds on January 7, 2019

Chinese scientists have successfully cloned hybrid rice seeds Wang Kejian, the State Key Laboratory of Rice Biology, China Institute of rice research, Chinese Academy of Agricultural Sciences, has established a rice apomixis reproductive system by using gene editing technology, successfully cloned hybrid rice seeds, so that hybrid rice characters can be stably inherited to the next generation The results were published online in Nature Biotechnology on the evening of April 4 In the experiment, the researchers selected Chunyou 84, an indica japonica hybrid rice, as the model variety for the research of rice apomixis Using CRISPR / cas9 gene editing technology, four genes related to rice reproduction were knocked out in Chunyou 84, resulting in the Apomixis of hybrid rice and the same clone seed as hybrid rice Through further testing, the researchers determined that the progeny plants cultivated by cloning seeds were highly similar to the first generation hybrid rice "This work proves the feasibility of hybrid rice apomixis, which is a major breakthrough in the field of apomixis research and has great theoretical significance." Yuan Longping, the "father of hybrid rice" and academician of the Chinese Academy of engineering, said he hoped that researchers would make further efforts to apply the results to production as soon as possible Https://www.nature.com/articles/s41587-018-0003-0 New Year's document issued by the National Office of the Communist Party of China Re emphasizes, giving researchers greater autonomy Recently, the general office of the State Council issued the notice on the implementation of documents related to the granting of greater autonomy to scientific research institutions and personnel (hereinafter referred to as the notice) The notice stressed that when formulating relevant regulations and specific measures, all regions and departments should clearly "give researchers greater decision-making power of technical route" and "the person in charge of scientific research project can independently set up scientific research team according to the needs of the project, and make corresponding adjustment in combination with the implementation and progress of the project" We will further promote the decentralization of scientific and technological management authority, make it clear in the notice, promote the implementation of budget adjustment and instrument procurement management authority, promote the implementation of project process management authority, and improve the internal management system of scientific research institutions Http://www.gov.cn/zhengce/content/2019-01/03/content_.htm office with artificial intelligence "brain" makes workplace more comfortable Fierce competition for talents has made Berlin's office more intelligent There will be a sensor network in the office building that can measure temperature, lighting, humidity, carbon dioxide concentration, etc and connect to the cloud platform This technology is called "brain", which is a self-learning software that can analyze all the data received by itself and optimize the operation of the building For example, if part of a building is unoccupied, it can turn off lights and heating systems If the conference room is crowded, it can breathe more oxygen Users enter the building through a smartphone app that knows their schedule and may suggest sitting next to a window or meeting floor Https://www.dailymail.co.uk/sciencetech/article-6556727/offices-grow-brains-companies-seek-attract-smarter-workers.html neonatal genome sequencing can discover unknown genetic risks as genome sequencing becomes more and more common in clinical practice, there are still questions about its use and role in newborns Can sequencing provide actionable insights? Can you find a discovery that is important to your child's future health? A recent study published in the American Journal of human genetics reveals the answers to these questions The researchers report that genome sequencing can identify the risks of various diseases that other instruments may not be able to detect It is important to understand early that some of these diseases may be monitored and intervened to improve the health of newborns "The sequencing results may cause parents to feel uneasy, but they may also take useful and even life-saving interventions in advance," the researchers said "Only time will tell."

Sun Yongcai, the leader of Fuxing high-speed train development, said at the representative forum of "reform pioneers" in the field of science and technology held in Beijing that in order to realize the operation of 350 km / h train, they have cooperated with dozens of scientific research institutes at home and abroad to jointly create a strong engine leading innovation "The equipment manufacturing industry is the most important tool of the country In the future, CRRC will continue to improve its internal skills and take the initiative to take the responsibility of independent innovation."
