RNAi in the Rhizarian Phytopathogen Plasmodiophora brassicae: The Causal Agent of Clubroot Disease in Cruciferous Crops

Advanced Science, EarlyView.
This study uncovers an unusual RNAi pathway in the rhizarian pathogen Plasmodiophora brassicae. In the absence of Dicer, a Drosha‐like RNase III protein supports the biogenesis of predominant 21‐nt small RNAs, and two Argonaute proteins mediate small RNA‐guided silencing.

空间物理学科发展战略研究

Kongjian kexue xuebao, 2023
空间物理学是人类进入空间时代后迅速发展起来的一门新兴的多学科交叉的前沿基础学科。其将太阳和太阳风控制的日球层空间作为一个系统，研究太阳/太阳风与行星/彗星的上层大气、电离层、磁层乃至星际介质之间的相互作用。空间物理学从本质上讲是一门实验科学，空间物理探测是空间物理学发展的基础。进入新世纪，随着空间基础设施和人类高技术活动的日益频繁，空间物理学进入新的发展阶段，强调科学与应用的密切结合。近年来，空间物理学取得了一系列重要进展。本文对接国家自然科学基金委地球科学部“宜居地球−地球系统科学”的顶层战略设计 ...

AS‐TLC‐Based High‐Throughput Screening Integrated with CuAAC Optimization Strategy Facilitates the Rapid Discovery of YTHDC1 Inhibitor

Advanced Science, EarlyView.
We developed Affinity Selection Thin‐Layer Chromatography (AS‐TLC) as a method for high‐throughput screening (HTS) of compound mixtures. Furthermore, we integrated activity assays with AS‐TLC and identified a YTH domain‐containing protein 1 (YTHDC1) inhibitor. Building on this hit, we applied copper(I)‐catalyzed azide–alkyne cycloaddition (CuAAC) click

Scalable Multilayer PTFE‐Reinforced Membranes for Durable, High‐Current‐Density Hydroxide Exchange Membrane Water Electrolysis in Dilute Alkali

Advanced Science, EarlyView.
Low‐Tg HEMs are designed to improve membrane‐electrode adhesion by promoting intimate contact with catalyst layers. After hydration, the membrane develops a hydrogel‐like network that supports water uptake and ion transport while retaining mechanical robustness.

Symbiont‐Induced HSP83 Establishes Two‐Tiered Control of Antifungal Immunity in an Invasive Beetle–Fungus Complex

Advanced Science, EarlyView.
In an invasive beetle–fungus complex, the mutualist Leptographium procerum induces host HSP83 and modulates Toll‐dependent antifungal immunity. HSP83 mediates two‐tiered control by associating with selected fungal recognition receptors and restraining Dorsal‐driven antimicrobial peptide transcription.

Emergent Magnetism, Heavy Electrons, and Pressure‐Induced Reentrant Superconductivity in the Iron Substituted 4d Transition‐Metal Sulfides

Advanced Science, EarlyView.
This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.
