Trans‐Omics Integration Reveals That the Kidney Contributes to Systemic Aging via Sexually Dimorphic Accumulation of Glycosphingolipids

MedComm, Volume 7, Issue 3, March 2026.
Female‐specific renal GluCer accumulation disrupts mitochondrial quality control via a conserved purine‐mTORC1 pathway, triggering a wave of uremic toxins into the systemic circulation that constitutes a female‐biased vulnerability toward renal‐driven multiorgan senescence.

Climate Shapes the Ratio Between Aboveground Plant Biovolume and Topsoil Macronutrients Worldwide

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Soil nutrients are a major limiting factor for plant biomass, yet paradoxically, some of the most productive ecosystems thrive in nutrient‐poor soils. Here, we conducted a global field survey in 421 sites across all major biomes to investigate the environmental factors controlling the ratio between plant biovolume (a proxy for aboveground ...

Characterization of the Nature of Organic Matter in Carbonate Rocks: Implications for Geological and Environmental Studies

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Organic matter in carbonate rocks plays a crucial role in processes such as fluid flow regulation, carbon sequestration, contaminant transport, and hydrocarbon recovery. This study employed multimodal spectroscopic techniques, including fluorescence imaging and Fourier transform infrared (FTIR) spectroscopy, to characterize the spatial ...

Hydrazine Synthase From Anammox Is Inhibited by Linear and Aromatic Alkynes

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Linear and aromatic alkynes inhibit anammox in culture and in wetlands. The inhibition by alkynes is specific to the hydrazine synthase, a key enzyme in the anammox pathway. ABSTRACT N2O emissions by nitrifiers are often estimated using selective inhibitors, such as 1‐alkynes.

Extreme Droughts Push Heterotrophic Functions Above Baseline Levels in a Neotropical Ecosystem

Global Change Biology, Volume 32, Issue 3, March 2026.
Using tank bromeliads, we experimentally assessed post‐drought resistance and recovery of ecosystem multifunctionality under realistic drought scenarios. We focused on three key functions in these small yet abundant Neotropical freshwater ecosystems: litter decomposition, microbial respiration, and photosynthetic efficiency.
