Bacteria Optimize Tumble Bias to Strategically Navigate Surface Constraints
Advanced Science, EarlyView.The study investigates how Escherichia coli optimizes tumble bias (TB) to navigate surface constraints effectively. Using single‐cell tracking and modeling, it reveals that bacterial surface residence time decreases with increasing TB, stabilizing near the wild‐type mean TB (≈0.25), where surface diffusivity peaks.

Weak and Tunable Adhesion–Clutch Drives Rapid Cell Migration and Glioblastoma Invasion
Advanced Science, EarlyView.This study proposes that adhesion–clutch can mediate both cell motility and immobilization depending on the force amplitude. Weak adhesion–clutch is well‐suited for cell migration, without forming strong adhesions that impede cell motility. It propels rapid dendritic cell migration controlled by extracellular chemicals, as well as pathologically ...

Advanced Science, EarlyView.Non‐symmetric metal‐quinone network (MQN) nanoarchitectonics with controllable morphology and size are constructed by manipulating interphase solute diffusion during the nanoprecipitation process. Self‐propelled nanomotors developed from non‐symmetric MQN nanoarchitectonics exhibit chemotactic autonomous motion toward overexpressed H2O2 in tumor ...

Advanced Science, EarlyView.pMM‐PCL, made up of pretreated macrophage menbrane and polycaprolactone, boasts the adsorption of harmful myelin debris in the microenvironment of spinal cord injury. Abstract After spinal cord injury (SCI), a mass of myelin debris derived from injured myelin sheath will be consistently generated and induce macrophages to be foam cells.

Advanced Science, EarlyView.This study uncovers a novel mechanism and therapeutic targets in obstetric antiphospholipid syndrome (OAPS). Antiphospholipid antibody/ß2‐glycoprotein I complex boosts CCL2 and TNF‐α expression in decidual macrophages via TLR4‐NF‐κB. CCL2 accumulates on endothelial surfaces via ACKR1, recruiting monocyte‐derived CCR2+ macrophages, driving inflammation,
