Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

Advanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Platycodon grandiflorus–Derived Nanovesicles Sensitize Gastric Cancer to T Cell Killing via Ferroptosis‐Driven Membrane Mechanical Remodeling

Advanced Science, EarlyView.
Plant‐derived nanovesicles from Platycodon grandiflorus act as bioactive lipid delivery platforms that transport γ‐linolenic acid into gastric cancer cells. This lipid cargo promotes ferroptotic lipid peroxidation, remodels membrane mechanics, and increases tumor‐cell susceptibility to cytotoxic T‐cell attack.

An Injectable and Self‐Reinforced Piezoelectric Hydrogel for Irregular Bone Defects Regeneration: Dynamic Epigenetic Regulation Approach

Advanced Science, EarlyView.
An injectable and self‐reinforcing RSF‐based piezoelectric hydrogel conforms to irregular bone defects and progressively strengthens in situ, overcoming the trade‐off between injectability and mechanical stability. Mechanical loading generates bioelectrical cues that promote P300‐mediated H3K9 acetylation and upregulate PTH1R expression, thereby ...
