Membrane‐Mediated Force Transduction Drives Stick‐Slip Motion of Lipid Vesicles
Advanced Science, EarlyView.A rotating magnetic field actuates a ferromagnetic particle inside a lipid vesicle, generating internal flows that induce stick‐slip propulsion near a surface. Membrane properties—elasticity, excess area, and phase behavior—modulate this motion by shaping stress dissipation and force transduction.

Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance
Advanced Science, EarlyView.DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...
