Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...
