Near Room‐Temperature Ferromagnetic Phase Achieved in 4d Ruthenate via Interfacial Ferrimagnetic Coupling and Octahedral Rotation Engineering

open access: yesAdvanced Science, EarlyView.
Transition metal oxides combining strong spin‐orbit coupling, near‐room‐temperature ferromagnetism, and high conductivity are rare. A Ca0.5Sr0.5RuO3 interfacial phase between LaMnO3 layers has all these features, high Tc, enhanced magnetization, and reduced coercivity.

Small Extracellular Vesicles Orchestrate Cisplatin‐Induced Ototoxicity: Potential Biomarker and Targets Discovery

open access: yesAdvanced Science, EarlyView.
Cisplatin causes reactive oxygen species accumulation, leading to apoptosis and inflammation in cochlear hair cells. Small extracellular vesicles primarily derived from the damaged hair cells likely contribute to cisplatin‐induced ototoxicity, carrying a variety of microRNAs and proteins.

Probing the Challenge of P‐Type Semiconductors in Long‐Chain VOC Detection: 3D Micro‐Flower Zinc Cobaltate Heterojunction Sensors

open access: yesAdvanced Science, EarlyView.
Fe@WO3/ZnCo2O4 n‐p heterojunction sensor exhibits excellent room‐temperature sensing toward tetradecane, with a low detection limit of 78.4 ppb and short recovery time. The good performance is attributed to synergistic effects from heterojunctions, heteroatom doping, oxygen vacancies, high‐energy facets, and theoretical validations.

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

open access: yesAdvanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

open access: yesAdvanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...
