3D Nanofibrillar Matrix Stiffness Modulates Extracellular Vesicle Cargo and Pro‐Tumour Functions

Journal of Extracellular Vesicles, Volume 14, Issue 10, October 2025.
ABSTRACT Extracellular matrix (ECM) stiffness and extracellular vesicles (EVs) are critical regulators of tumour progression, yet their interaction in three‐dimensional (3D) microenvironments remains poorly understood. Most studies on ECM stiffness and EV biology rely on 2D cultures, which do not capture the complexity of the tumour microenvironment ...

Uncertainty Quantification of Fluid Leakage and Fault Instability in Geologic CO2 ${\text{CO}}_{2}$ Storage

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Geologic CO2 ${\text{CO}}_{2}$ storage is an important strategy for reducing greenhouse gas emissions to the atmosphere and mitigating climate change. In this process, coupling between mechanical deformation and fluid flow in fault zones is a key determinant of fault instability, induced seismicity, and CO2 ${\text{CO}}_{2}$ leakage.

The Employment Non‐Discrimination Act and Board Gender Diversity

British Journal of Management, Volume 36, Issue 4, Page 1578-1597, October 2025.
Abstract Many US states have adopted Employment Non−Discrimination Acts (ENDAs) to ensure workplace equity and prohibit discrimination based on sexual orientation or gender identity. This study examines if and how the staggered introduction of ENDAs across US states from 2001 to 2018 influences board gender diversity.
