25-9 China issues long-term guideline on IP

China’s State Council and the CPC recently issued a guideline on building up its intellectual property (IP) strength between 2021 and 2035. By 2035, China’s overall IP competitiveness will be at the forefront of the world as a world-class IP powerhouse with Chinese characteristics on six aspects: China will build a comprehensive, well-structured, IP legal […]

28-9 China’s R&D spending and patenting on new heights

According to a White Paper released by the State Council, China’s R&D spending was about 370.97 billion U.S. dollars, ranking the world’s second, and the ratio of R&D to GDP reached 2.4 percent. Nearly 1.35 million utility patent applications were filed and 441,000 were granted, and 69,000 international PCT patent applications were submitted. By the […]

27-9 CAS Shanghai converts syngas aerosols to medium- and long-chain chemicals using Clostridium ljungdahlii

A group around Weihong JIANG at CAS Institute of Plant Sciences in Shanghai metabolically engineered autotrophic Clostridium ljungdahlii to efficiently co-produce three important bulk chemicals, isopropanol, 3-hydroxybutyrate (3-HB), and ethanol (together, IHE), using syngas (CO2/CO). The engineered strain was further optimized to reassimilate acetic acid and synthesize 3-HB by introducing heterologous functional genes. Finally, the […]

24-9 Team at CAS Tianjin Institute of Industrial Biotechnology synthesises starch from CO2 in a cell-free system

The group used computational design to draft an artificial anabolic pathway from CO2 to starch.  First, CO2 is reduced to methanol by an inorganic catalyst. Next, in a cell free system with spatial and temporal segregation, methanol is covered to starch through 11 core reactions driven by hydrogen and including engineered enzymes. Reaction rates in […]

13-9 China launches Gaofen 5-02 satellite for hyper spectral observation of air pollution

The satellite developed by the CAS Hefei Institute of Material Science is equipped with a total of 7 remote sensing instruments, including a main greenhouse gas monitor (GMI), an atmospheric trace gas differential absorption spectrometer (EMI), a multi-angle polarization detector (DPC) and a high-precision polarization scanner (POSP). The four payloads operate synchronously for a dynamic […]
