Brain Network Dynamics of Local and Global Predictive Processing in Aging

Advanced Science, EarlyView.
Separation of concurrent whole‐brain networks in source‐reconstructed magnetoencephalography (MEG) data suggests that healthy aging reorganizes, rather than uniformly attenuates, neural responses elicited from hierarchical auditory violations. Enhanced early sensory deviance processing alongside reduced higher‐order cognitive responses suggests a large‐

Real‐Time Monitoring of Mass and Mechanical Properties in Single Cells and Multicellular Spheroids

Advanced Science, EarlyView.
This study introduces photothermally actuated microcantilevers combined with optical microscopy to simultaneously measure morphology, mass, and mechanical properties of cellular systems in real‐time. The findings link cytoplasm‐dominated mechanical energy dissipation to the Q‐factor as a novel biophysical parameter.

A Robust Bio‐Supportive Hydrogel Patch for Full‐Thickness Repair of Gastroesophageal Defects

Advanced Science, EarlyView.
Gastroesophageal defect repair remains a formidable clinical challenge plagued by high leakage and life‐threatening complications. We develop a double‐disc, highly crystalline PVA‐based RBS hydrogel patch featuring suture‐free sealing, robust acid/enzyme resistance and mechanical durability.

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers

Advanced Science, EarlyView.
A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

FAK Mediated Coordination of Extracellular Matrix Remodeling and Cellular Mechanics Impairs Nanomedicine Delivery in Solid Tumors

Advanced Science, EarlyView.
FAK orchestrates a mechanical barrier limiting nanomedicine accumulation in solid tumors by coupling ECM remodeling with cytoskeletal tension. Genetic or pharmacological FAK inhibition dismantles this barrier, enhances clathrin‐mediated uptake and penetration, and overcomes delivery limitations to improve antitumor efficacy.
