[quick news] PNAs paper cited controversy on November 19, 2018, questioned by Chinese and Japanese scholars

The PNAs paper is controversial Chinese and Japanese scholars have written an article questioning that "the impact of rice cultivation on global warming may be nearly twice as high as previously estimated" - the research results published in PNAS two months ago have aroused the doubts of scholars in the industry On November 16, Yan Xiaoyuan, a researcher of Nanjing Soil Research Institute of Chinese Academy of Sciences, and Akiyama Bozi, a scholar of Japan Agricultural Research Institute (Naro), jointly published an essay on PNAs, pointing out that they believed that the above-mentioned papers were inappropriate Krite krite, the first author and corresponding author of the paper and a scholar from the American Environmental Protection Association, also wrote a response at the same time Kritee believes that these countries focus on methane emission reduction in rice planting strategy, but ignore another greenhouse gas, N2O Yan Xiaoyuan believes that kritee and others not only exaggerate the emission of N 2O from rice fields, but also exaggerate the potential of emission reduction, which is misleading The paper proposes that "through the joint management of water, nitrogen and carbon, the net climate impact of rice planting can be reduced by 90%", which is impossible to achieve Http://www.pnas.org/content/early/2018/11/13/1816208115 Many top scientists gathered in Beijing to participate in the ceremony Li Jiayang and Zhang Qifa, winners of life science award, Ma Dawei, Feng Xiaoming, Zhou Qilin, and Lin benjian, winners of mathematics and computer science award, attended the ceremony Yuan Longping, another life science award winner, recorded a video even though he didn't show up The guests present at the award ceremony include Rao Yi, Bao Zhenan, Yu Jinquan, Ma Huateng, Xu Xiaoping, etc The future science award is the first non-governmental science award in China It emphasizes that the award is completed in Greater China, which has a huge international impact, and has originality, long-term importance or time tested scientific research work The individual bonus is US $1 million, which is jointly donated by four donors Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2018-11 / 19 / content_ HTM? Div = - 1 "mini brain" helps to study brain development disorders such as epilepsy According to the online report of Nature magazine recently, a research team led by neuroscientist alysson muotri of the University of California, San Diego, USA, induced human stem cells to form tissues from the cortex They grew hundreds of brain organs over a period of 10 months, and tested the cells of each brain organ to confirm that the gene set they expressed was the same as that in a normal developing brain The team continued to record the surface activity of these "mini brain" EEG, and found that the brain waves of "mini brain" were similar to those of babies born 25-39 weeks gestation This progress may help scientists to study the early development of the brain With regard to the ethical concerns of "mini brain", Muotri said that the current research is still in a very primitive initial stage, and if there is evidence that "mini brain" has self-awareness, he would consider stopping the project Https://www.nature.com/articles/d41586-018-07402-0 rapid propagation technology realizes the planting of six generations of wheat in a year According to daily mail, NASA has developed a rapid propagation technology, which conducts 22 hours of LED irradiation on crops every day, aiming to optimize photosynthesis and accelerate the plant propagation cycle The results show that only two generations of wheat can be grown in the previous year, and six generations can be grown in this way Scientists say the technology could be used to increase crop yields for disease and climate adaptation, allowing plants to survive extreme climate change Https://www.dailymail.co.uk/sciencetech/article-6397961/plant-speed-breeding-lead-climate-change-resistant-crops.html Facebook uses AI to predict suicide risk Facebook Use artificial intelligence to scan the user's account to see if the user has potential suicide risk; then mark the user with high suicide risk and let the staff judge whether to contact the rescue personnel At present, this function has achieved good results In the first month of the launch, Facebook solved nearly 100 suicide risk incidents and completed 3500 early warning reports in a year This AI can not only monitor individuals, but also monitor and predict the response behavior of their friends https://www.npr.org/2018/11/17/668408122/facebook-increasingly-reliant-on-a-i-to-predict-suicide-risk
