Impact Crater Hydrothermal Systems Support Rapid Microbial Enrichment and Diverse Metabolic Potential

Geobiology, Volume 24, Issue 6, November/December 2026.
ABSTRACT Impact crater hydrothermal systems, formed after asteroid and comet impacts, have been proposed as promising habitats for life on early Earth and as key targets in the search for life on planetary bodies such as Mars, since they provide liquid water and active geochemical turnover.

Hypercapnia Induces Mitochondrial Adaptations and Alters Glutamine Metabolism to Drive a Distinct Metabolic Phenotype in Monocytes

Immunology &Cell Biology, Volume 104, Issue 10, Page 943-963, November‐December 2026.
Elevated CO2 (hypercapnia) is a feature of serious lung diseases, for example COPD and contributes to poor patient prognosis through modulation of immune cell function. Here we employ state‐of‐the art metabolomic and isotope tracing approaches to reveal CO2‐dependent mitochondrial alterations linked to suppressed ATP, proline and glutamate levels in ...

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis

Immunology, Volume 179, Issue 3, Page 418-433, November 2026.
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...

The OsWRKY15‐OsSUT3 Regulatory Module Enhances Rice Pollen Fertility by Mediating Sucrose Allocation to Anthers

Plant Biotechnology Journal, Volume 24, Issue 11, Page 5684-5701, November 2026.
ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

Population genomics of heterosporous lycophytes: allopatric speciation and historical persistence through paleoclimatic fluctuations

The Plant Journal, Volume 128, Issue 3, November 2026.
SUMMARY Speciation is the fundamental process driving the origin of earth biodiversity. While speciation mechanisms have been revealed in many plant taxa, the evolutionary dynamics of heterosporous lycophytes remain largely unexplored. Here, we used the Selaginella sanguinolenta group, comprising seven montane species in eastern Asia, as a model system.
