Aging Cell, Volume 25, Issue 10, October 2026.Time‐restricted feeding delays vascular aging and cardiac remodeling by fostering a symbiotic gut microbiota that bolsters barrier function and amplifies short‐chain fatty acid production. ABSTRACT Time‐restricted feeding (TRF) restricts food intake to daily windows, yet its efficacy against vascular aging and underlying mechanisms remain unclear. Here,

Advanced Science, Volume 13, Issue 50, 7 September 2026.This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Global Challenges, Volume 10, Issue 9, September 2026.How much does the reaction environment matter in photocatalytic CO2 reduction? Using Cu‐doped SrTiO3 as a model catalyst, the solid–gas configuration is found to outperform liquid and pressurized systems, revealing that reaction‐phase engineering plays a decisive role in controlling efficiency and product selectivity. ABSTRACT Carbon dioxide conversion
