A laboratory in Wuhan is on the cusp of being cleared to work with the world’s most dangerous pathogens. The move is part of a plan to build between five and seven biosafety level-4 (BSL-4) labs across the Chinese mainland by 2025, and has generated much excitement, as well as some concerns.

In the current study, Prof. ZHAO teamed up with Prof. Nielsen Jens of Chalmers University of Technology and Prof. Grininger, demonstrated that duplicated ACP in RtFAS are redundant in terms of fatty acid biosynthesis. Researchers replaced either ACP with a short chain thioesterase (TE) from bacteria and showed that the engineered RtFAS can overproduce short/medium chain fatty acids. Similarly, when either ACP was replaced by a methylketone synthase (Mks2), the engineered RtFAS produced long chain methyl ketones. Importantly, this modification strategy was generalized towards other fungal type I FASs, and various modified FASs showed new functions as expected. This study facilitated new opportunities to engineer fatty acid biosynthetic machinery for expanded product portfolio.

To understand the photoprotection mechanism, Prof. HAN Keli and his coworkers at Dalian Institute of Chemical Physics use the femtosecond transient absorption spectroscopy and time-dependent density functional theory and find the ultrafast photoisomerization mechanism of SA and SM in neutral aqueous solution.

Recently, Prof. Ming Li and his research team in Institute of Semiconductor, Chinese Academy of Sciences and Institut National de la Recherche Scientifique-énergie, Matériaux et Télécommunications (Canada) report a reconfigurable and single-shot incoherent optical signal processing system for chirped microwave signal compression.
Chinese scientists discovered five new species of plants in Yarlung Zangbo Grand Canyon in Tibet.
China is also looking beyond our solar system in playing a role in the search for life in space as we just mentioned the FAST radio telescope in Guizhou.
This clip shows testing of high speed train technology in the laboratory of the Institute of Mechanics at the Chinese Academy of Sciences in Beijing. The experimental platform is 274 meters long, the world's largest platform of its kind to conduct tests and experiments on aerodynamics of high speed trains traveling at 500 kilometers per hour. Check the video to experience a train being tested at 250 km per hour along the experiment platform. How fast can China's high speed train go?
