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.

Nankai University team develops synthetic spider silk

A team around LU Zunfeng at Nankai University in Tianjin has prepared an artificial spider silk made from polyacrylic acid and silica nanoparticles. It consists of hierarchical core-sheath structured hydrogel fibers, which are reinforced by ion doping and twist insertion. The fiber exhibits a tensile strength of 895 MPa and a stretchability of 44.3%, achieving mechanical properties comparable to spider silk. The material also presents a high toughness of 370 MJ m−3 and a damping capacity of 95%.

Chinese NMPA approves Alzheimer drug based on gut microbiota improvement

Oligomannate (GV-971: sodium oligomannurarate) developed by Shanghai Green Valley Pharmaceuticals was approved by the NMPA as a drug to improve cognitive improvement of patients with moderate Alzheimer disease (AD). The multi-center randomized Phase III study which led to the approval was done for 36 weeks at 34 first-class hospitals in China on a total of 818 patients with mild to moderate AD between ages 50 to 85. The results showed that oligomannate produced a statistically significant improvement in cognitive function after 4 weeks of administration, and the effect persisted. Oligomannate is thought to improve cognitive function by improving dysbiosis of intestinal microbiota, suppressing abnormal increase of intestinal bacterial metabolites, regulating inflammation of the peripheral and central nervous system, and by reducing excessive phosphorylation of tau, resulting in less deposits of amyloid protein. GV-971 was co-developed by Ocean University of China, CAS Shanghai Institute of Materia Medica (PI GENG Meiyuand Green Valley Pharmaceutical Co.

China launches 6G research, practical start seen in 10 years

China has established two offices to develop 6G technology, one at the Ministry of Science and Technology (MOST), the other as an group of 37 experts from colleges, research academies and enterprises. Most of the 6G performance indexes will outnumber those of 5G by 10 to 100 times, with a maximum transmission speed of 1Tbps, meaning a high-definition movie can be downloaded within a second. Extended reality (XR) which combines AI and AR is expected to create virtual objects in physical reality, changeable at will. It will enable people at different geographic locations to feel like they were actually in the same space, with a seamless connection between devices and senses.

China forms alliance to extract uranium from sea water

According to China’s National Nuclear Corporation (CNNC), China has formed an innovation alliance to foster the research and application of extracting uranium from seawater. The alliance, led by CNNC, comprises about 20 research institutions and universities, and will focus on the technology and products used in the extraction process. It is estimated that seawater contains about 4.5 billion tonnes of uranium is, about 1,000 times of the land proven reserves. However, concentration is extremely low, making it a huge challenge to develop cost-effective seawater uranium extraction technology.

Tianjin group invents flexible electronic devices with soft sensors and circuits within liquid droplets

Inspired by natural jellyfish and rotifers such as coelenterates and floating organisms, the group of HUANG Xin at Tianjin University has developed a fully flexible “smart droplet robot” of 150 to 600 microliters size. The ultra-compact and fully programmable liquid smart robot can move, deform and sense under different environmental conditions. It can carry multiple sensors, e. g., for temperature, humidity, optical signals, stress, glucose, food toxins and wireless energy collection. It could be applied to genetic testing, chemical synthesis, and application of drugs, and has the potential to become a “blood vessel doctor” who enters the human body and conducts examinations and treatments.
