Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio‐Hybrid Robots

Advanced Science, EarlyView.
Crustacean exoskeletons, repurposed from food waste, are engineered into sustainable bending actuators combining biotic structure with synthetic control. The augmented exoskeletons achieve rapid and robust motion with lightweight body and can be used as part of robotic manipulators, grippers and swimmers.

Senescent Synovial Intimal Fibroblasts Aggravate Osteoarthritis by Regulating Macrophage Polarization and Chondrocyte Phenotype Through ANGPTL4‐α5β1 Axis

Advanced Science, EarlyView.
Senescent synovial intimal fibroblasts (SIF) are identified as key drivers of osteoarthritis. They promote M1 macrophage polarization and cartilage degeneration via the ANGPTL4–α5β1 axis, regulated by transcription factors EGR1 and ATF3. Pharmacological inhibition of this pathway alleviates disease, revealing SIF senescence as a promising therapeutic ...

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

Advanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Microgel‐Based Hierarchical Porous Hydrogel Patch with Adhesion and Resilience for Myocardial Infarction

Advanced Science, EarlyView.
This study develops a hierarchically porous hydrogel patch strategy (HPMP), based on gas‐shearing microfluidics and an aqueous two‐phase system to fabricate porous microgels as microgel‐based bioinks. The porous microgels with controllable porous structure exhibit excellent cellular behavior.

Resilient Calvarial Bone Marrow Supports Retinal Repair in Type 2 Diabetes

Advanced Science, EarlyView.
Skull bone (calvarium) marrow in diabetic mice stay structurally intact and keeps making blood cells, unlike the bone marrow of the leg bones. The skull marrow is exposed to cerebrospinal fluid (CSF), which contains protective molecules called oxysterols.

A Shear Thickening Colloidal Suspension Functioning via Progressive Impact Jamming with Persistent Lubrication Layer

Advanced Science, EarlyView.
An ionic liquid‐based shear‐thickening fluid (ILSTF) exhibits lubricated dynamics from strong shear thickening to impact‐triggered jamming. A persistent nanometric solvation layer around silica governs both the shear thickening saturation in rheology and jamming front propagation under dynamic impact compression.

Encapsulating Textiles with Dynamic Covalent Networks for Sustainable and Efficient Oil Spill Cleanup

Advanced Science, EarlyView.
By encapsulating industrially relevant fabrics with dynamic imine networks, we show that the resulting composites exhibit exceptional oil absorbtion capability and chemical recyclability. It is poised for sustainable oil spill cleanup. ABSTRACT The development of high‐performance sorbents for oil spill remediation is highly desirable, which now calls ...
