Cybersecurity in China improves, but slowly

Acording to a talk at Beijing Cyber Security Conference, around 48.5 percent of China’s government agencies and 56.3 percent centrally-administered state-owned enterprises have deployed security operation centers, and the response time to security events has been reduced to less than one hour from about three days in 2016.

In the first half of 2019, more than 100 million enterprises’ computers had security software installed, while the number in 2016 was around 60 million. The repair cycle for computer system vulnerabilities has dropped to 16 days from 35 days in 2016. In a special campain, the Office of the Central Cyberspace Affairs Commission, the Ministry of Industry and Information Technology, the Ministry of Public Security and State Administration for Market Regulation evaluated more than 400 popular apps on the collection of personal data, and around 100 apps were asked to make improvements in data protection.

CAS Institute of Microbiology develops new microdroplet reaction screening device, coupled to cell sorting by FACS

The nanodrop system achieves nanoliter volume addition of different reagent components through high-precision micro-volume control. It is compatible with 96 and 384-well plates and can be programmed according to the pre-filled mineral oil plate. The minimum volume that can be accurately filled with a low-cost probe is 1 nL, and the volume standard deviation is less than 11% when the loading volume is 5 nL. The droplets can be by centrifugation. Multi-step reactions and concentration gradient configurations can be achieved by multiple injections of reagents. The  system was used for PCR screening and single-cell phenotypic screening of pathogenic microbial single-cell resistance genes. It was also fused to a FACS system and used for single cell gene expression analysis of animal cells.

Strain-engineered bacterial consortium drives fuel cell

A group at the Institute of Microbiology of CAS has described a novel microbial fuel cell. Genetically modified cyanobacteria assimilate CO2 in visible light to form D-lactic acid, which they cannot utilize and excrete into the medium. A second microorganism, Shewanella bacteria, oxidises the D-lactic acid and conducts the electrons formed via a membrane protein complex to an electrode. In this way, the bacterial consortium produced an unprecedented average energy density of 135 mW.m2 for 40 days.

Silk-based composite membrane designed for salinity-gradient power plants

“Osmosis power plants” could use the potential difference between salt water and fresh water, e.g. in the estuaries of large rivers, to generate electrical energy by reverse electrodialysis. Liping WEN and colleagues from the Institute for Physics and Chemistry at CAS in Beijing investigated suitable composite membranes for this purpose. They produced a nanoporous composite membrane from silk nanofibrils and aluminium oxide as carrier substrate. The negatively charged surface of the fibroin ensures ion transport, while the amphoteric aluminum oxide allows for current flow over a wide pH range. Depending on the salt concentration, energy densities of up to 2.86 W.m2 were achieved.

Shanghai: AI-directed „customized bus” service for commuters

In an attempt to provide better commuting services for office workers, Shanghai residents in some places can now reserve a seat in a  customized bus, with a one-click reservation on their mobile phone via Alipay. The price is 18 ¥, about 1/10 the prize of a taxi. The bus route is calculated by AI according to the homes and destinations of the passengers, and the bus does not stop during the journey, only at the gate of the customer and the  sites of the office building, which greatly improves the running speed compared to traditional lines. The “Traffic Brain” software developed by Alipay automatically simulates the route, station and departure schedule. The attendance rate of the line is reportedly above 80% since the launch. A representative of Alipay claims that such kind of customized bus will cover all China within three years.

China has 39 Beidou satellites in orbit, will complete global network in 2020, seeks interoperability with Russia’s GLONASS

According to China’s Satellite Navigation System Management Office, China’s Beidou Navigation Satellite System (BDS) currently has 39 satellites in orbit. China plans to send five to seven more BDS satellites into space this year and two to four in 2020, which will help fully complete a BDS global network. China promotes integration of BDS with Russia’s GLONASS. While the GLONASS network mostly serves high-latitude regions, China’s Beidou navigation system mainly focuses on providing networks for the low-latitude areas. Bilateral cooperation between China and Russia will create a larger, broader, more stable and more robust satellite network, with more accurate positioning to challenge GPS. Beidou participates in various international organizations such as the International Civil Aviation Organization and the International Maritime Organization. In the future, BDS will be further integrated with the Internet, the Internet of things, 5G and big data.

China defines “Chinese Blue Sky Index”

China is often troubled by haze pollution from accelerating industrialization, in Beijing also from desert dust. As a result, air pollution control has become an important issue, as symbolized by the keyword “Beijing blue” for blue skys in Beijing. 

Scientists from the CAS Institute of Atmospheric Physics and Peking University have now defined a Chinese blue days index, which contains a double meanings of sunny days and clean air. The index combines meteorological and environmental data and shows a steady increase in Chinese blue days (CBD) during 1980-2014. Three low-value centers can be found in the southeast Sichuan Basin, southern Hebei, and northeast Guangxi, with annual mean average CBD of 74, 86 and 92, respectively. The minimum/maximum trends (-7.5/9.5 d/10y) appeared in Yangtze-Huai River Valley (YHRV) / southwestern China (SWC). Approximately 42% of stations showed a prominent, increasing trend and approximately 23.4% of stations showed a decreasing trend.

TU Youyou will direct artemisinin research center in Beijing

The construction of a 1600 m2 Artemisinin research centre was started in Beijing’s Daxin Science Park and is scheduled to go into operation in 2021. It is headed by Professor Youyou TU, who was awarded the Nobel Prize in Medicine for her discovery of the anti-malaria drug in 2015, China’s first ever Nobel Prize. Artemisinin is part of the mugwort Artemisia annua, which has been known for thousands of years in traditional Chinese medicine for the treatment of malaria.
