Advanced Science, EarlyView.Administration of opioids activates ephrinB2‐EphB1 receptor signaling. Activated EphB1 receptors induce GRK2‐mediated phosphorylation of MOR at Ser375, which initiates the internalization of MOR and reduces opioid antinociception at the behavioral level. ABSTRACT Opioids are the primary treatment for severe pain in clinical practice.

Unlocking the Full Potential of Jumping Condensation on Microstructured Surfaces
Advanced Science, EarlyView.Microcone arrays exhibit a spacing‐dependent transition between jumping and non‐jumping condensation. Dense microstructures favor full Cassie droplets, which depart cleanly, while wider spacing favors partial Cassie droplets that retain a localized wet region initiating new nucleation. These findings establish a link between microdroplet morphology and

Advanced Science, EarlyView.Electroporation combined with NCLX inhibition and Ca2+ delivery induces mitochondrial Ca2+ overload in PDAC cells, triggering pyroptosis, DAMP release, and antitumor immune activation. Simultaneously, suppression of tumor‐derived SPP1 weakens SPP1–CD44 signaling and remodels macrophages toward an antitumor phenotype, thereby enhancing CD8+ T‐cell ...
