Microalgae yield can be enhanced by knocking out carbonic anhydrase CA2

A joint research team of CAS QIBEBT and Ruhr-University Bochum found that cytosolic carbonic anhydrase (CA2) is a key sensor of the extracellular carbon dioxide level in microalgae. By knocking out this gene in Nannochloropsis, the algae showed higher pH tolerance, sustained pH hemostasis, stimulated energy intake and enhanced photosynthesis, resulting in in ~40% elevation of biomass accumulation rate […]

Two-step process converts cellulose into polycycloalkanes, a high-density aviation biofuel

A joint research team of CAS Dalian Institute of Chemical Physics and Tianjin University have established a process to convert cellulose to 2,5-hexanedione with high selectivity, obtaining 71.4% of 2,5-hexanedione carbon yield after separation. In a second step, this chemical was converted to a C12 and C18 polycycloalkane fuel having a branched structure by an […]

China and France collaborate in space programs

During Xi Jinping’s visit in France in March 2019, space authorities from both sides signed an agreement to step up cooperation in space exploration. China will fly French experiments on its Chang’e-6 mission to return samples from the Moon in 2023-24, earth observation missions based on the China-France Oceanography Satellite (CFOSat) will be extended to ocean […]

Rejuvenation of aging cells may help to cure osteoarthritis using gene therapy: CAS Institute of Zoology

Senescent mesenchymal stem cells (hMSCs) are found in cartilage tissues isolated fromosteoarthritis patients suggesting a role of these cells in the disease. A joint research group of CAS Institute of Zoology, Institute of Biophysics and Peking University have now found in animal experiments that a protein, CBX4, protected hMSCs against cellular senescence through the regulation of […]

CAS team reports progress in calcium-ion batteries

The group of Yongbing TANG at CAS Shenzhen Institutes of Advanced Technologies has reported on a new type of calcium ion batteries (CIB) which uses activated carbon as anode and tin as a cathode. Reportedly this CIB has a good rate and cycling performance as well as high capacity and working voltage, and it retained 84 […]

Gut microbiota may help to maintain body temperature

It is known that during cold exposure animals sustain their body temperature by activating heat production from Brown Adipose Tissue (BAT), promoting “browning” of white adipose tissue. As shown in mice experiments by John R Speakman, CAS Institute of Genetics and Developmental Biology, groups of gut microbiota where eradicated using different antibiotics. The animals lacking gut […]
