Puerarin Targets MIC19 to Suppress Mitochondrial Metabolism of Tumor‐Infiltrating Tregs and Enhance Anti‐tumor Immunity

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
Puerarin targets mitochondrial MIC19 in tumor‐infiltrating Tregs, impairing their immunosuppressive function and enhancing antitumor immunity. This study uncovers the metabolic dependency of tumor‐infiltrating Tregs and highlights a potential metabolic‐targeted immunotherapeutic strategy for liver cancer. Abstract Regulatory T cells (Tregs) are pivotal

Effects of Aging on Magnetic Mineralogy of Natural Volcanic Glass: Implications for Geomagnetic Paleointensity Recorders

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Natural volcanic glasses are well represented in the geologic record, and typically contain near‐ideal single‐domain particles required for standard Thellier‐type absolute paleointensity experiments. Young (<∼50–100 ka) glasses have been demonstrated to reliably record Earth's magnetic field.

Onion‐Mitochondria Inhibit Lipopolysaccharide‐Induced Acute Lung Injury by Shaping Lung Macrophage Mitochondrial Function

open access: yesAdvanced Science, Volume 12, Issue 48, December 29, 2025.
Proposed model of orally administered onion mitochondria (O‐Mit) uptake by lung macrophages and fuse with macrophage mitochondria (M‐Mit). This fusion reprograms the metabolism of dysfunctional M‐Mit in lipopolysaccharide‐induced murine acute lung injury by modulating dynamin‐related protein 1 (DRP1) phosphorylation and cardiolipin peroxidation ...

Unlocking Tropical Forest Complexity: How Tree Assemblages in Secondary Forests Boost Biodiversity Conservation

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
Secondary forests are crucial for achieving COP15/16 conservation goals. An operational national approach was developed to identify and characterise forest ecosystems based on the dominant tree species in the canopy, serving as indicators for ecosystem extent and condition.
