The Migration–Development Nexus Revisited: A Place‐based Mobility Perspective from the Borderlands

open access: yesDevelopment and Change, Volume 56, Issue 6, Page 1197-1227, November 2025.
ABSTRACT Migration, a fundamental characteristic of planetary life and human livelihood, has been considered a key driver of development. However, as identified by critical migration and mobility scholars, the assumed positive relationship to development has been predominantly informed by a neoliberal, managerial and sedentary view of migration ...

Mimicking breast cancer tissue—3D bioprinted models in accurate drug sensitivity tests

open access: yesVIEW, Volume 6, Issue 5, October 2025.
Three‐dimensional (3D) bioprinted tumor models provide a novel method for studying drug sensitivity. This study compares drug response patterns of 3D bioprinted breast cancer models with xenografts and syngeneic tumors, showing that bioprinted models more accurately reflect the drug sensitivity and tissue heterogeneity of syngeneic tumor model.
