Neuroimmune Microenvironment Reprogramming via Immuno‐piezoelectric Transducers for Synergistic Stem Cell Therapy in Traumatic Brain Injury

Advanced Materials, EarlyView.
A novel immuno‐piezoelectric transducer is innovatively developed. This device promotes neural stem cell (NSC) differentiation and maturation via ultrasound‐induced electrical stimulation and it amplifies the therapeutic efficacy of NSC in traumatic brain injury (TBI) by modulating the immune microenvironment. This piezoelectric transducer with “immune‐

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Dynamic Fibrous Hydrogels for Stem Cell Homing and In Situ Bone Regeneration

Advanced Science, EarlyView.
A dynamic fibrous hydrogel (DFH) is developed by covalent crosslinking of gelatin with tea‐derived trichomes, which integrates the structural and compositional fidelity of native extracellular matrix with photothermal and oxidative responsiveness, introducing a novel “stem cell recruits stem cell” strategy that orchestrates co‐homing of endogenous and ...

Nasal Mucosa‐Derived Extracellular Vesicles as a Systemic Antiaging Intervention

Advanced Science, EarlyView.
This study shows that nasal mucosa‐derived extracellular vesicles (nmEVs) exert systemic anti‐ageing effects in mice by restoring circadian rhythm, suppressing cellular senescence, and improving cognitive function. In aged human bone marrow mesenchymal stem cells, nmEVs reverse senescence‐associated phenotypes and reactivate core clock gene expression.

Ferroptosis‐Mediated Hippocampal Neuronal Loss Post‐mTBI: Chromatin Accessibility Profiling and Single‐Nucleus Transcriptomics

Advanced Science, EarlyView.
Hippocampal single ‐nucleus transcriptomes and chromatin accessibility after mild traumatic brain injury reveal dentate granule neuron vulnerability driven by ferroptosis. The c‐Jun–Tmsb4x–Slc2a2 axis modulates lipid peroxidation and iron dysregulation.
