A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity

Advanced Science, EarlyView.
The resistive hypogravity exosuit is a lightweight wearable robotic exosuit that uses pneumatic artificial muscles to restore Earth‐like metabolic and muscular demands during locomotion in low gravity. Tested on healthy subjects in Earth and simulated Moon gravity, the suit restores energy expenditure and muscle activation without altering gait ...

Tumor‐Derived CDC37 Inhibits Antigen Cross‐Presentation in Dendritic Cells and Impairs Anti‐Tumor Immunity in Breast Cancer

Advanced Science, EarlyView.
Extracellular vesicle (EV)‐packaged CDC37 are released from TMBhiCTLlo breast cancer cells with high CDC37 expression, and internalized into endo/phagosomes of dendritic cells (DCs). Within these compartments, CDC37 locked HSP90–antigen complex, preventing antigen release into the cytosol.

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics

Advanced Science, EarlyView.
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...

Peptide Electrostatic Modulation Directs Human Neural Cell Fate

Advanced Science, EarlyView.
This study explores the effect of charge on the bioactivity of peptide‐based supramolecular materials. The design of a peptide library with varying charges that self‐assemble into supramolecular fibers is presented, demonstrating how the surface charge of these fibers, used as artificial extracellular matrices, influences the fate of human neural ...

4D Insights into Coral Biomineralization: Effects of Ocean Acidification on the Early Skeleton Development of a Stony Coral

Advanced Science, EarlyView.
Early coral skeletons grow through formation of two co‐joined zones, rapid accretion deposits and thickening deposits. Advanced imaging and simulations reveal that ocean acidification reshapes these zones, shifting the coral portfolio of mineral phases which alters skeletal resistance to mechanical stress.

A Methodology for Deciphering the Transmembrane Resistance Variability of Supported Lipid Bilayers

Advanced Science, EarlyView.
This work shows that transmembrane resistance variability, due to lipid packing defects, can be quantified by analysing the dielectric properties of Supported Lipid Bilayers. The proposed methodology provides an analytical tool for optimizing SLB design with improved stability and functionality for bioelectronic and biomimetic applications. Abstract In
