Converting environmental challenge into chemical resource: New catalyst for nitrite-to-ammonia conversion

Tsinghua University Press

Water pollution caused by nitrite (NO₂⁻) from agricultural runoff and industrial discharge presents significant challenges to ecosystem health and human wellbeing. Innovative water treatment technologies are essential for addressing this growing environmental concern. A new cobalt-iron layered double hydroxide decorated on 3D titanium dioxide arrays (TiO₂@CoFe-LDH/TP) shows promise as an effective electrocatalyst for nitrite reduction, offering a practical approach to converting harmful pollutants into valuable ammonia while minimizing unwanted byproducts during the electrochemical process.

Autonomous AI agents in healthcare

Technische Universität Dresden
Peer-Reviewed Publication

Artificial intelligence (AI) in healthcare is rapidly advancing beyond traditional applications. Autonomous AI agents are gaining significant attention for their potential to fundamentally transform medicine. However, researchers at the Else Kröner Fresenius Center (EKFZ) for Digital Health at TUD Dresden University of Technology highlight a growing mismatch between the capabilities of autonomous AI agents and existing medical device regulatory frameworks in the US and Europe. In their publication, they propose innovative regulatory approaches to close this gap while ensuring high patient safety standards. The article has been published in the scientific journal Nature Medicine.

Genetic test predicts obesity in childhood

University of Copenhagen - The Faculty of Health and Medical Sciences
Peer-Reviewed Publication

A new genetic test, based on data from more than five million people, can identify people at risk of severe obesity. The test can be performed on children before their genetic risk starts to shape their weight, from age five, which may support early prevention strategies.
