The service provides information on the first new virus strain isolated in China by the Centers for Disease Control and Prevention, electron micrographs, novel nucleic acid detection primers and probe sequences. It integrates global coronavirus genes and genomic big data, and helps to establish a global coronavirus data platform. Voice broadcast, CAS Institute of Microbiology

According to a press release of Nanjing University, entangled photons could be fired from a drone at points A and B 100 meters away when reaching an altitude of several tens of meters. The photons met interference from atmospheric turbulence, rainwater, sunlight, etc., but still reached the ground almost unchanged. Japan JST China news, January 23, 2020

The plan will build a digital resource system with five types of data:  agricultural natural resources important agricultural varieties resources rural collective assets rural housing bases, farmers and new farmers, and  digital agriculture It is designed to promote computerization of cultivation industry, smarter livestock industry, smarter fisheries, digitalization of seed industry, diversification of new business types, and a comprehensive process of quality and safety management, and increase the production capacity of digitalization of agriculture.

During a meeting on January 18, 2020, CAS president BAI Chunli announced that the CAS plans for the world’s largest high-energy synchrotron in Beijing’s Huairou district. With other major equipment and 11 new scientific and educational facilities in the park, total investment will sum up to 10.4 billion CN¥ or 1.5 billion US$. The academy will also build new labs in Shanghai, in Hefei (Anhui province), the Xiongan New Area (Hebei province) and in the Greater Bay Area connecting Guangdong-Hong Kong-Macao. By the end of last year, the academy had launched 58 pilot projects in fields such as space technology, green industry and regenerative medicine The CAS has also launched a new version of its cloud database and opened it for researchers around the world, including cloud calculation, data search and storage, analytical software and community networking.The network includes scientific data on energy, oceanography, biosciences, health and other frontier fields.

According to a press conference of the Ministry of Water Affairs, China has now established a network of hydrological observatories of its large rivers and their major tributaries, for flood countermeasures and water quality control. Observation points now number 121,000, with 3,154 stations, 14,286 surface water quality stations and 26,550 groundwater quality stations. Japan JST China news January 21, 2020

Mikania micrantha, dubbed “mile-a-minute” weed, is one of the top 100 worst invasive species and one of the most harmful invasive plants, also in south China. WAN Fanghao, Chinese Academy of Agricultural Sciences, and colleagues have prepared a 1.79 Gb reference chromosome map and have shown that half of the genome is composed of long terminal repeat retrotransposons, including a whole genome duplication event. Mikania micrantha achieves higher photosynthetic capacity by CO2 absorption at night to supplement its carbon fixation during the day, as well as enhanced stem photosynthesis efficiency. Furthermore, the metabolites of the plant can increase the availability of nitrogen by enriching microbes that participate in nitrogen cycling pathways.

The new technology is based on an improved method to detect motion blur. A parameterized motion blur kernel is mapped into the 3D pose space of the camera to obtain a 3D pose set, and the intersection of the 3D pose sets (shared pose set) corresponding to multiple image patches is obtained. Compared with state-of-the-art methods, the detection accuracy of the proposed method is claimed to be improved by more than 20%. https://ieeexplore.ieee.org/document/8760546
