Zhipu XuebaoCarbon monoxide (CO) is an essential component of air, and it arises from anthropogenic sources and natural sources. These different sources of CO have significant differences in carbon and oxygen isotopic values, therefore the carbon and oxygen isotopic

Advanced Sustainable Systems, EarlyView.Bisphenol‐A polycarbonate is upcycled via a simple one‐pot reaction into an aromatic Mannich polyol, which serves as a precursor for fabricating poly(urethane‐isocyanurate) (PUR‐PIR) aerogels. PUR‐PIR aerogels, prepared with different isocyanate indices, exhibit high porosities, high specific surface areas, ultralow thermal conductivity, and excellent ...

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.

Advanced Science, EarlyView.Skullcapflavone II (SkII) significantly alters serine metabolism in gastric cancer cells by directly targeting the L‐serine transporter SLC1A4, thereby inhibiting L‐serine uptake rather than de novo synthesis. This disruption of serine metabolism by SkII leads to increased oxidative stress and consequent mitochondrial damage.
