Chinese company builds satellite system Hongyan to allow 10 cm precise location

According to a statement of China Great Wall Industry Co., the company will start construction of a satellite system Hongyan which will allow users access to their exact position accurate to about 10 centimeters in less than one minute, no matter where they are, The Beidou system will obtain basic positioning data and then transmit it to ground control, which will use algorithms to improve accuracy before sending the information to the Hongyan constellation. Hongyan satellites, carrying augmentation devices in low orbit, will then further process the positioning data and deliver it to end users around the globe. China Aerospace intends to carry aloft about 60 Hongyan satellites before the end of 2022, and then place more than 200 smaller satellites in orbit to form a network called Kuilong with global reach. Kuilong would revolutionize a wide range of businesses including the internet of things and smart transportation.

Rhodomyrtosone B from Rose myrtle: a potential drug against MRSA

As shown by Haibo TAN and colleagues at CAS South China Botanical Garden, rhodomyrtosone B shows high antibacterial activity with a MIC of 0.62 – 1.25 µg/L against MRSA and 2.5 µg/L against vancomycin-resistant Enterococcus faecalis. They showed that the mechanism of action of rhodomyrosone B and its derivatives relates to perturbation of bacterial membrane potential and an increase in membrane permeability. By screening a series of synthetic derivatives for anti-resistant bacteria activity and their structure-activity relationship, up to 4-5 times more active lead compounds were obtained and their antibacterial activity verified in vivo experiment. Rhodomyrtosone B is obtained from the leaves of Rhodomyrtus tomentosa (Aiton) Hassk, also named Rose myrtle, and leaves of this plant are used for the treatment of wound infections in traditional Chinese medicine.

Group at CAS SIAT finds inexpensive black phosphorus preparation for photocatalysis

The team around YU Xuefeng at the CAS Shenzhen Institutes of Advanced Technology (SIAT) has developed a low-cost metal-free photocatalyst based on black phosphorus for effective photocatalysis. Using a simple ball-milling technique, the team converted red phosphorus and urea to black phosphorus and black phosphorus/CN complexes in large-scale, among which the material cost of black phosphorus in the photocatalyst was estimated to be just 0.016 RMB pear gram. By forming P-N bonds, black phosphorus and CN interacted to form a stable binary which showed broad absorption as well as effective charge separation, and possessed abundant active sites, giving rise to excellent photocatalytic performance. Without using a co-catalyst, the metal-free catalyst emitted H2 consistently at a rate as high as 786 μmol·h-1·g-1 and RhB was decomposed in merely 25 mins during visible light irradiation.

CAS Institute of Industrial Biotechnology achieves vitamin-B12 synthesis in E. coli using synthetic biology

The group of ZHANG Dawei divided the vitamin B12 biosynthesic pathway into six modules into which they engineered a total of 28 genes from R. capsulatusBrucella melitensisSinorhizobium meliloti 320, ,S. typhimurium, and Rhodopseudomonas palustris. Each module was expressed in E. coli on individual plasmids or incorporated into the E. coli genome. After metabolic engineering to ameliorate cobalt chelation and remove module 4 bottlenecks, as well as optimization of fermentation conditions, vitamin B12 production was increased 250fold to 307 µg per g dry cell.

CAS QIBEBT develops big-data mining tools for microbiome research

The group of SU Xiaoquan at CAS QIBEBT has established a “microbiome search engine” which is based on two indices: a microbiome novelty score MNS evaluates the compositional uniqueness of a microbiome sample at the time of its birth, whereas a microbiome attention score MAS quantifies the scientific attention devoted to the microbiome by counting the number of close neighbors of the microbiome. A microbiome focus index MFI, which is derived from MNS and MAS, then measures the impact and contribution of a microbiome sample to explorations for novel microbiomes.  The team hopes to thus identify “sleeping beauty” microbiomes that are still very novel in structure at present quantifies the number of close neighbors in the microbiome.
