China’s Beidou-3 system is nearly complete and opens a “belt and road” corridor in space

Last week, China launched No. 18 and 19 of the Beidou-3 series satellites (BDS). The basic constellation of 20 Beidou-3 satellites will be completed by year’s end. By then, the network will provide basic navigation service for countries or regions involved in the Belt and Road Initiative. Beidou-3 has a higher positioning accuracy, to within 2.5 to 5 meters. Domestically, BDS plays a significant role in traffic regulation, as there are nearly 6.3 million public and private vehicles, including buses, express delivery cars and trucks equipped with the Beidou system for navigation.The number is expected to rise by 10 percent year-on-year. BDS applications have been extended to monitor trains, tourist coaches and vehicles carrying dangerous goods. Marine departments send information about typhoons and sea conditions to fishermen through BDS. BDS helps anti-corruption departments check whether officials use government cars for private purposes. It also plays a role in protecting historic sites, and tracking wild animals like leopards. Farmers grow crops using tractors, drones and other machines equipped with the system. Herdsmen use mobile phones to monitor their cattle and sheep wearing BDS locators on grasslands. BDS is also helping track containers on cargo ships, expose mine risks, locate leaks on gas pipelines, provide navigation for marathon runners, and to find missing elderly people and children.

BDS products have now entered more than 70 countries and regions including over 30 countries along the Belt and Road. The close economic ties between China and ASEAN have paved the way, as in Southeast Asian countries located in low latitudes, BDS is more accurate than GPS. Thus, BDS plays already an important role in transport and port management in Pakistan, land planning and supervision of river transport in Myanmar, precision agriculture and pest and disease monitoring in Laos, and urban modernization and tourism development in Brunei.

As early as August 2016, already over 700 Chinese smartphone models supported BDS, accounting for 21 percent of all smartphones sold in China. Since then, use of the system has much expanded in China and gradually extended over the belt and road. The globalization boom for BDS is expected for around 2021 when about 30 Beidou-3 satellites will span the globe.

Longevity might be related to high autophagy competence

Autophagy is a mechanism to selectively degrade damaged proteins from cells and organelles in the lysosome. A research group at CAS Institute of Zoology has investigated peripheral blood leukocyte transcriptome data of 171 longevity families in Hainan (centenarians, their F1 offspring and spouses of F1 offspring) and found the up-regulation of autophagy – lysosomal signal pathway genes the most significant signal. Four related genes (CTSB ATP6V0C WIPI1 and ATG4D) are also upregulated in human embryonic lung fibroblasts possibly enhancing autophagy and reducing senescence. An overexpression of Atg18a, a related gene in Drosophila melanogaster led to a significant extension of the lifespan of Drosophila.

China will serve communication and trade in the Arab world with its Beidou satellite system

The Beidou Navigation Satellite System (BDS) will have gone global by around 2020. The first forum on Beidou cooperation between China and Arab countries was held in 2017 in Shanghai. In April 2018, the China-Arab States BDS/GNSS Center was officially inaugurated in Tunisia, and in the first half of 2019 Tunisia will host the 2nd forum on “belt-and-road” China-Arab cooperation.

Antibiotic resistance genes in Chinese waters correlate with human activities

The groups of YANG Jun and ZHU Yongguan at the CAS Institute of Urban Environment have analyzed patterns of antibiotic resistance genes (ARG) in 42 natural lakes and reservoirs across China. Using high-throughput DNA sequencing, they detected 167 ARGs and 9 mobile genetic elements mostly coding for efflux transporters. Human activities strongly correlated with the normalized abundance of ARGs, and their composition in south/central China was different from that in the north.

A hyperthermophilic Ni-Fe hydrogenase drives the reduction of pyruvate to lactate in a cell-free system

The group of Yunhong SONG at CAS Institute of Industrial Biotechnology in Tianjin cloned a soluble enzyme I (SHI) from Pyrococcus furiosus and overexpressed it in Thermococcus kodakarensis. Purification was achieved in one step using a nickel-loaded column. The rSHI purified by this method was coupled with an FMN-containing diaphorase (DI) to form a new electron transport chain. which utilized hydrogen as a reducing agent to regenerate NADH, used to convert pyruvic acid into lactic acid.

CAS group solves structure and mechanism of Mycobacterium respiratory supercomplex by cryo electron microscopy and ESR

A team around Zihe RAO at CAS Hefei Institute of Material Science has solved the structure of a respiratory supercomplex isolated from Mycobacterium smegmatis at3.5-Å resolution by cryo electron microscopy. Using low-temperature electron spin resonance equipment, a new electron transfer mechanism coupled with oxime oxidation and oxygen reduction was revealed. From the perspective of structural biology, it was confirmed that there is a direct interaction between superoxide dismutase and respiratory chain complex, as well as its role in scavenging potential free radicals and synergistic redox reactions. Targeted blockage of the respiratory chain of pathogenic bacteria is an important strategy for the development of drug-resistant tuberculosis drugs.
