First‐Principles Investigation of the T‐ and M‐Centers in Silicon Using Meta‐GGA Functionals

Advanced Theory and Simulations, EarlyView.
The relaxed structure for (a) T‐center and (b) M‐center. The calculations on the T‐center demonstrate excellent agreement with the HSE06, reinforcing the efficiency of meta‐GGA approaches for accurate defect characterization in Si. The M‐center is introduced, revealing promising quantum optical properties.

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

Advanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.
