Advanced Science, EarlyView.This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

Advanced Science, EarlyView.A pH/MMP dual‐responsive Bifidobacterium longum (BL) hydrogel (INPs@BL@Gel) functionalized with baicalin, tyrosine, and inulin is constructed. It enables gastric protection, inflammation‐targeted release, and prolonged intestinal colonization. By remodeling gut microbiota, elevating beneficial neuroactive metabolites (homovanillic acid, short‐chain ...

VALIDATING OPERATIONAL FOOD SECURITY INDICATORS AGAINST A DYNAMIC BENCHMARK [PDF]
Food security indicators used in practice are static in nature, thereby foregoing the key dimension of food security. This study develops an explicitly forward-looking food insecurity indicator and relative to this dynamic benchmark, we evaluate the ...

Advanced Science, EarlyView.Cu‐MXene interfacial catalysts provide a promising platform for electrochemical NOx upcycling to ammonia. The synergy between Cu active sites and conductive, surface‐tunable MXene supports promotes NOx adsorption, intermediate stabilization, and selective NH3 formation while suppressing competing hydrogen evolution, offering a route toward sustainable ...

Food security, poverty, and economic policy in the Middle East and North Africa [PDF]
In MENA, household food insecurity, which is closely related to poverty and undernourishment, is most severe in rural areas and concentrated within Iraq, Sudan, and Yemen. 25% of the MENA population may be poor and 7% undernourished. The key to increased

Advanced Science, EarlyView.Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

Advanced Science, EarlyView.ROS‐Responsive H2S Hydrogel (HAPPF) Coordinated Regeneration for High‐Quality Diabetic Wound Repair.A self‐regulating dynamic hydrogel is developed to deliver a fluorogenic H2S donor in response to excessive ROS. Released H2S acts as a master regulator to resolve chronic inflammation (M2 polarization), restore VEGF‐driven angiogenesis, and rebalance ...
