Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

Advanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Ultrasound‐Mediated Biotransfection of Engineered Bone Marrow Mesenchymal Stem Cells in Treated Bone Defects through Intracellular Cavitation

Advanced Science, EarlyView.
Ultrasound‐mediated biotransfection through intracellular cavitation increases plasmid nuclear translocation and gene transfection efficiency by 284.7% and 131.6% in engineered bone marrow mesenchymal stem cells (BMSCs) compared to traditional ultrasound‐targeted microbubble destruction techniques. The maintained bone morphogenetic protein 2 expression

Starch Acetate Grafted to MXene Composite Surpasses Room Temperature Liquid Electrolyte Performance for All‐Solid‐State Lithium‐Ion Batteries

Advanced Science, EarlyView.
By leveraging click chemistry, starch acetate is integrated with MXene quantum dots (MX‐QDs). While the composite electrolyte is electrically insulating, MXene stabilizes the anionic species while acting as a filler to boost mechanical properties. Optimized composition exhibits exceptional ionic conductivity of 14.8 mS cm−1, lithium cation transfer ...

A Water‐Triggered Sensor for Self‐Powered Flood Alarming

Advanced Science, EarlyView.
Urban floods related to global warming generally cause significant casualties. Traditional cable flood warning systems are costly, while wireless ones face power limitations. This research proposes a self‐powered flood sensor with a water‐triggered Galvanic battery, enabling rapid flood warnings with great promise of low cost and long service lifetime.
