Thermally Regulated Methanol Selectivity in Photo‐Thermo Methane Oxidation Through Interfacial Methyl Transfer

open access: yesAdvanced Science, EarlyView.
Photo‐thermo cascade catalysis enables highly selective methane‐to‐methanol conversion over Au‐ZnO, achieving a CH3OH production rate of ∼800 µmol h−1 with 86% selectivity. Thermal activation gates the transfer of methane‐derived methyl intermediates from ZnO to Au, thereby redirecting the reaction pathway toward methanol formation. ABSTRACT The direct

Enriched Soil Organic Carbon Underpins Long‐Term Stable Crop Productivity Across China's Croplands

open access: yesAdvanced Science, EarlyView.
Quantifying the nonlinear relationships and causal effects of soil organic carbon (SOC) on crop stability reveals specific critical thresholds and saturation points. This partitions the national SOC spectrum into three functional phases. Integrating these spatial delineations with high‐resolution maps of marginal gains pinpoints regions with the ...

An Integrated Framework Coupling Hierarchical Hyperspectral i‐trait Screening, Gene Identification, and Functional Validation for Genetic Dissection of Salt Tolerance in Cotton

open access: yesAdvanced Science, EarlyView.
An integrated phenomics–genomics framework captures dynamic salt‐stress responses in laboratory‐grown cotton seedlings through time‐series hyperspectral imaging and non‐destructive i‐trait extraction. Hierarchical screening identifies biologically relevant, heritable, and non‐redundant traits for high‐resolution GWAS, identifying GhST7.

Topology‐Driven X‐Shaped DNA as a cGAS Stimulator to Promote Dendritic Cell Activation and Antitumor Vaccine Efficacy

open access: yesAdvanced Science, EarlyView.
X‐shaped DNA promotes multivalent cGAS assembly and enhances cGAS‐STING signaling. When conjugated with antigenic peptides, the resulting X‐DNA‐based peptide vaccine promotes dendritic cell activation, antigen presentation, and antitumor T‐cell responses.

Combinatorial Tuning of Multigene Biosynthetic Pathways based on RNA Interference

open access: yesAdvanced Science, EarlyView.
Small RNA sequencing identifies candidate endogenous Pol III promoters, and subsequent fluorescence screening measures knockdown efficiency to assess promoter strength. Combining promoter strength and shRNA target position enables fine‐grained RNAi regulation of multigene pathways. This strategy enhances β‐carotene production in Schizochytrium sp.
