High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

open access: yesAdvanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

TP53 Loss Elevates NF‐κB‐IFN‐β‐MHC‐Ia Signaling to Promote NK Cell Resistance in Osteosarcoma

open access: yesAdvanced Science, EarlyView.
TP53 loss in a transforming or osteosarcoma cell promotes cytosolic DNA accumulation, activating NF‐κB‐dependent IFN‐β production. Autocrine IFN‐β signaling increases cell‐surface HLA‐Ia expression, strengthens inhibitory KIR signaling in natural killer cells, and thereby enables the affected cell to evade NK cell‐mediated cytotoxicity.

Towards a Compositional Framework for Describing Human Phenotypes

open access: yesAdvanced Science, EarlyView.
The Phenotype Assembly Method (PhenoAM) decomposes phenotype variables into measurable Features and typed Qualifiers, enabling standardized, machine‐readable Phenome Data Elements (PhenoDEs) that preserve measurement context. Applied in the International Human Phenome Project (IHPP), the framework yields 58 371 PhenoDEs and supports component‐level ...

A 3D‐Printed SFE‐Graded Alloy Mitigates Cryogenic Discontinuous Plastic Flow and Hydrogen Embrittlement

open access: yesAdvanced Science, EarlyView.
A novel strategy features gradient composition and stacking fault energy‐tuned (CoCrMn)100‐2xFexNix fabricated via in situ alloying additive manufacturing. This design circumvents cryogenic discontinuous plastic flow and hydrogen embrittlement of metallic materials under quasi‐static loading and hydrogen‐rich environment relevant to lunar polar ...

SAT1‐Induced Spermidine Depletion Potentiates Food Allergy

open access: yesAdvanced Science, EarlyView.
Spermidine depletion, driven by upregulated spermidine/spermine N1‐acetyltransferase (SAT1), potentiates food allergy by promoting mast cell degranulation through autophagy suppression. SAT1 physically interacts with the long noncoding RNA Cdk19os to inhibit Atg5 and Atg7, disrupting autophagic flux.

Multimodal Imaging of Hypoxia, Metabolism and pH in Feline Sarcoma Using Hyperpolarized 13C MRI and PET

open access: yesAdvanced Science, EarlyView.
This work presents a clinically deployable simultaneous PET/MRI workflow which integrates hyperpolarized 13C imaging of metabolism and extracellular pH with [18F]FMISO PET to characterize hypoxia, acidosis, and metabolic reprogramming in feline sarcoma.

A Hepatocyte‐to‐Stellate Cell Axis Couples Alternate‐Day Fasting to Liver Fibrosis Resolution via ATG7 S‐Nitrosylation

open access: yesAdvanced Science, EarlyView.
Alternate‐day fasting suppresses mitochondrial complex II assembly via SDHAF4 to upregulate hepatocyte eNOS. The resulting nitric oxide S‐nitrosylates ATG7 at C184 in hepatic stellate cells, restraining autophagic flux and preventing their profibrotic activation.
