New Chinese database bridges global gaps in plant trait data

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers from the Wuhan Botanical Garden of the Chinese Academy of Sciences (CAS) have built the Chinese Seed Trait Database (CSTD), which has been published in New Phytologist. This innovation overcomes longstanding language barriers (e.g., Chinese-to-English data translation) and enhances the completeness of global seed trait data, providing an invaluable resource for advancing large-scale plant science research.

Researchers reveal Acyl chain length-dependent conformational dynamics of Acyl carrier protein

Dalian Institute of Chemical Physics, Chinese Academy Sciences
Peer-Reviewed Publication

A team led by Prof. WANG Fangjun from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences revealed how acyl carrier protein (ACP) adapts its conformation to accommodate acyl chains of varying lengths, and revealed acyl chain length-dependent conformational dynamics of ACP at the molecular level.

Tracing the origin of near-infrared emissions emanating from manganese (II)

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

The origin of near-infrared (NIR) emission by Mn²⁺ has sparked intense academic debates for decades. However, to date, none of the proposed hypotheses have garnered widespread consensus. This study validates that Mn²⁺ positioned within a 6-coordinate octahedral lattice, exhibiting a strong crystal field akin to the AlO₆ site, possesses the capability to produce NIR emission. The results of this study offer a novel perspective for the progress of efficient Mn²⁺-doped NIR phosphors.

Dispersion-engineered spin photonics based on folded-path metasurfaces

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

Spin photonics enables precise optical manipulation but faces bandwidth constraints. Researchers in China developed a folded-path metasurface platform that achieves independent dispersion and phase control of two opposite spin states, overcoming this fundamental barrier. This innovation realizes achromatic focusing, spin Hall effects, and spatiotemporal vector fields using a single metasurface, opening new avenues for a wide range of innovations, from dynamic control of light-matter interactions to the development of next-generation spin-photonic devices.
