Electron‐Rich Nickel Enabled by Charge Transfer in Multimetal Nanostructures for Efficient Ammonia‐to‐Hydrogen Conversion

open access: yesAdvanced Science, EarlyView.
A charge‐transfer‐engineered Ni catalyst derived from an atomically mixed layered precursor enables efficient ammonia‐to‐hydrogen conversion. Cr‐to‐Ni electron transfer creates electron‐rich Ni active sites that favor NH3 adsorption, modify the dehydrogenation energetics, and weaken N2 binding to facilitate product desorption. This electronically tuned

Structural Variants in the Human Genome Associated With Gut Microbiome and Blood Metabolic Traits With Potential Causal Links

open access: yesAdvanced Science, EarlyView.
Based on a multi‐omics cohort of 2002 individuals comprising high‐depth whole‐genome and metagenomic sequencing data, blood metabolites, and detailed questionnaires, we identified 138 859 high‐confidence SVs, uncovering 36 significant SV–microbiome associations and 48 SV–blood metabolite associations.

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

open access: yesAdvanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

Harnessing Methylselenol (CH3SeH): A Highly Effective Platform for Stimuli‐Responsive Delivery With Therapeutic Potential

open access: yesAdvanced Science, EarlyView.
Tools for controlled selenol delivery are crucial for exploring Se‐related biology and medicine, but compound platforms for triggerable release of CH3SeH remain lacking. Herein, we report the first general triggered platform (TD‐MSe) for efficient cyclization release of CH3SeH in live cells.

Vitamin K2 inhibits PGE2-mediated osteoblast ferroptosis by upregulation of CBR1 via the Nrf2/Keap1 pathway

open access: yesCommunications Biology
Osteoporosis is increasingly attracting attention. Studies have indicated a correlation between vitamin K2 levels and bone mass, but the specific mechanisms remain unclear. Therefore, this study aims to further elucidate the specific molecular mechanisms

Therapeutic Peptide‐Programmed Liquid‐Crystalline Topology Switching for pH‐Gated Postoperative Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A VDAP‐programmed liquid‐crystalline depot enables pH‐responsive postoperative immunotherapy for triple‐negative breast cancer. VDAP stabilizes a leakage‐resistant HII mesophase through peptide–lipid electrostatic assembly, whereas tumor acidosis unlocks the matrix and promotes graded topology remodeling toward a bicontinuous Im3̄m cubic phase for ...

Large Oncosomes Induce Pro‐Metastatic Stromal‐Myeloid Reprogramming

open access: yesAdvanced Science, EarlyView.
Large oncosomes systemically reprogram bone marrow mesenchymal stem cells through innate nucleic acid sensing, driving inflammatory and immunosuppressive remodeling that supports a metastasis‐permissive bone marrow environment, revealing a novel tumor‐host communication axis in cancer. ABSTRACT Bone metastasis can be facilitated by systemic remodeling,

Overcoming the *H‐NOx Coupling Bottleneck via Palladium‐Enabled Relay Catalysis on CuCo2O4 Toward Ampere‐Level Nitrate‐to‐Ammonia

open access: yesAdvanced Science, EarlyView.
Pd‐doped hollow spiny CuCo2O4 microspheres deliver ampere‐level electrocatalytic nitrate to ammonia. Cu and Co sites undergo relay catalysis for sequential nitrate reduction, while Pd accelerates water dissociation to supply abundant active hydrogen (*H).
