A fungal peroxidase can oxidise tetrahydropyranes to chiral hemiacetals or lactones A team at the CAS Tianjin Institute of Industrial Biotechnology has applied reaction engineering strategies using immobilized peroxygenase from Agrocybe aegerita (AaeUPO) for C-H bond selective hydroxylation reaction of cyclic ether molecules in organic solvents,  for the synthesis of optically pure chiral hemiacetal compounds . The immobilized peroxygenase which was already known to convert […]

Lanzhou University reports progress in prospecting a gold mine using muon imaging technology Liu Zhiyi and colleagues have used the penetration capability of muons for the detection of cultural relicts and ores. Using self developed detection equipment, they conducted field measurement in a gold mine in northwest China’s Gansu Province. Using six sets of equipment to scan a large area of the gold mine, the imaging results […]

China establishes AI education bases in 184 primary and secondary schools China’s Ministry of Education (MOE) has announced a list of 184 primary and secondary schools selected as artificial intelligence (AI) education bases, with the aim of better promoting the development of AI education. To facilitate the implementation of AI education, primary and secondary schools should mainly rely on information technology, general technology and other […]

Shanghai team develops super “CD-ROM” with petaByte storage capacity The CAS Shanghai Institute of Optics and Fine Mechanics and the University of Shanghai for Science and Technology have made a breakthrough in the research of ultra-large capacity and super-resolution three-dimensional optical storage. The team used the world’s first dual-beam controlled concentration-induced luminescence super-resolution optical storage technology to break through the diffraction limit  in […]

China’s “Speech Valley” in Hefei China Speech Valley, located in the western suburbs of Hefei City, east China’s Anhui Province, is China’s first national-level industry base focusing on voice and AI. Founded in 2013, this base is now home to over 2,200 enterprises.  iFLYTEK Co., Ltd. It was the first enterprise settled in China Speech Valley. As a leading […]

Launch of new research center for molecular imaging and theranostics in Beijing The center, managed by Peking University, is located in Huairou Science City in the northeastern suburbs of Beijing. With a planned construction area of 29,000 square meters and a total investment of approximately 630 million yuan (about 88.67 million U.S. dollars), the center is a key part of the multi-modal and multi-scale biomedical imaging […]

Simple and efficient plant transformation based on their active regeneration capacity A team at South China Botanical Gardenias developed RAPID, a fast and efficient plant genetic transformation methods, based on active regeneration capacity of plants. They found that positive organs and transformed individuals could be obtained rapidly by injection into the sweet potato stem segment, and transformation efficiency could be optimized in terms of […]

Chemical synthesis of tubercle bacillus cell wall components will help to develop drugs Lipoarabinomannan (LAM) from the Mycobacterium tuberculosis cell envelope represents important targets for the development of new therapeutic agents against tuberculosis. Researchers from the CAS Kunming Institute of Botany have developed a modular and efficient synthesis of Mycobacterium tuberculosis mannan cap lipoarabinomannan 101 sugar through a one-pot glycosidylation reaction and have achieved chemical synthesis of […]

A protein film derived from an insect shows excellent antimicrobial properties A research team at Xi’an Jian Tong University used a salt solution to induce a protein film-dressing self-assembling structure in the epidermis of the mot Astragalus membranaceus and showed that the tissue body has excellent biocompatibility. They also found that the tissue bodies have broad-spectrum antimicrobial properties towards Gram-positive and Gram-negative bacteria, as […]

Proton-exchange membrane in acid medium permits sustainable electrochemical conversion of CO2 to formic acid A Chinese-New Zealand team has developed a proton-exchange membrane system that reduces CO2 to formic acid at a catalyst that is derived from waste lead–acid batteries and in which a lattice carbon activation mechanism contributes. When coupling CO2 reduction with hydrogen oxidation, formic acid is produced with over 93% Faradaic efficiency. The system […]
