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.

Electrochemical‐Genetic Programming of Protein‐Based Magnetic Soft Robots for Active Drug Delivery
Advanced Science, EarlyView.This manuscript presents a protein‐based soft robot for active drug delivery. Stimuli‐responsive protein is rationally designed and processed into the substrate of robots. Superparamagnetic Fe3O4 nanoparticles are patterned on the substrate using an electrochemical method, enabling the robot to respond to external physical fields.

Advanced Science, EarlyView.A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Magnesium‐Mediated Electrochemical Synthesis of Ammonia
Advanced Science, EarlyView.This study demonstrates a lithium‐free, magnesium‐mediated electrochemical process for converting nitrogen (N₂) to ammonia (NH₃) under mild conditions. Using abundant materials, the system achieves ≈27% Faradaic efficiency at lower voltages than Li‐ and Ca‐mediated systems.

Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria
Advanced Science, EarlyView.A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...

Advanced Science, EarlyView.Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.
