Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

Advanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

TRIM47 Regulates Energy Metabolism via Glycolytic Reprogramming to Drive Hepatocellular Carcinoma Progression and Represents an Efficient Therapeutic Target

Advanced Science, EarlyView.
This study identifies TRIM47 as a key driver of liver cancer progression by promoting glycolysis through ubiquitin‐mediated degradation of the gluconeogenic enzyme FBP1. TRIM47 enhances glucose uptake, lactate and ATP production, and tumor growth and metastasis.

Targeting Itga8 Mitigates Neurogenic Bladder Fibrosis Driven by Trem2⁺ Macrophage‐Derived Fn1 via FAK/RhoA/ROCK Signaling

Advanced Science, EarlyView.
Normal bladders exhibit quiescent fibroblasts/macrophages, whereas neurogenic bladders show acute‐phase Itga8⁺ fibroblast expansion driven by Trem2⁺ macrophage‐secreted Fn1, which activates FAK/RhoA/ROCK signaling, promotes cytoskeletal remodeling, and upregulates pro‐fibrotic genes.
