Hump‐Shaped Relationship Between Microbial Carbon Use‐Efficiency and Soil Organic Carbon in Alpine Grasslands

open access: yesAdvanced Science, EarlyView.
On the Qinghai–Tibetan Plateau, microbial carbon use efficiency (CUE) peaks at intermediate soil organic carbon levels and declines thereafter. In carbon‐rich soils, the formation of stable mineral‐associated organic carbon is decoupled from microbial CUE.

Quantitative Porosity Engineering of Carbon Electrode in Lithium–Oxygen Batteries with Cell‐Level Gravimetric Energy Density Over 1500 Wh kg−1

open access: yesAdvanced Science, EarlyView.
While large pore volumes in carbon electrodes are believed to boost the energy density of lithium‐oxygen batteries, simulations and experiments show that excessive porosity increases electrolyte demand, reducing net energy gains. Optimizing pore structure for lean electrolyte operation enables >1500 Wh kg−1 pouch cells with good stability, redefining ...

Dual‐Chamber One‐Step Molding Actuator with Straight‐Curved Crease Prismatic Design for Large‐Range Motions and Structural Stability

open access: yesAdvanced Science, EarlyView.
A dual‐chamber origami prismatic actuator is designed by integrating straight‐curved creases with folded partitions, enabling large‐range, multidirectional motions and enhanced structural stability. The actuator exhibits anisotropic stiffness and multiple actuation modes, and is fabricated via single‐material, one‐step molding.

Integrative Omics Defines Metabolic Biomarkers and Genetic Regulatory Mechanisms of Mortality Risk

open access: yesAdvanced Science, EarlyView.
Understanding mortality mechanisms remains a fundamental challenge. Through multi‐omics analysis of a three‐generation chicken model, are identified 45,585 mQTLs and establish a 16‐metabolite predictor of mortality. An inflammation‐growth trade‐off and evolutionarily conserved pathways involving butyrate–microbiota interactions and L‐cysteine's dual ...
