Newly identified human aminoacyl‐tRNA synthetase complex interacting multifunctional protein 2 (AIMP2) loss‐of‐function mutations cause neurodevelopmental defects linked to cell death in a zebrafish model

The FEBS Journal, EarlyView.
Human AIMP2 mutations lead to severe neurodevelopmental defects and brain atrophy. Using patient‐derived fibroblasts from two individuals, we show decreased AIMP2 protein levels and overall protein synthesis. In a zebrafish loss‐of‐function model, the lack of AIMP2 leads to an increase in cell death and results in smaller brains.

Layered Radial Aquifer Model for Open‐Pit Mine Closure with Managed Aquifer Recharge

Groundwater, EarlyView.
A radially symmetric layered aquifer model (unconfined–aquitard–confined) coupled to a pit‐lake water balance is developed to screen managed aquifer recharge (MAR) after open‐pit mine closure. Dimensionless type curves quantify trade‐offs between pit recovery time, pumping/recycling, and unconfined mounding as functions of aquifer time scales, aquitard
