Experimental and computational methods for studying relaxation of aluminosilicate glasses: A review
Journal of the American Ceramic Society, Volume 108, Issue 6, June 2025.Abstract Relaxation plays a critical role in all glasses, especially those that undergo heat treatments for industrial applications. However, the fundamental mechanisms of relaxation are still poorly understood, especially in industrially relevant glasses such as aluminosilicate systems.

MTCH2 Suppresses Thermogenesis by Regulating Autophagy in Adipose Tissue
Advanced Science, Volume 12, Issue 17, May 8, 2025.This study demonstrates that MTCH2 acts as an evolutionarily conserved regulator of energy homeostasis across Drosophila, rodents, and humans. Adipose‐specific MTCH2 ablation enhances brown/beige adipose thermogenesis through Bcl‐2‐dependent autophagy, promoting energy expenditure and counteracting obesity‐associated metabolic disorders. These findings
