Riverine nitrate and nitrification cannot be the only sources for nitrate assimilation in the Amazon River Plume margins

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The Northern Amazon River Plume plays a crucial role in carbon sequestration and nitrogen cycling. This study quantified NO3− budgets along the plume during a period of high discharge, revealing NO3− uptake rates in excess of inputs from riverine sources and nitrification beyond 5°N.

Metatranscriptomics analysis of silicon transporters highlights underappreciated contributors to silica cycling in the Baltic Sea

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

Identical Platform, Divergent Publics: Sweden and Finland During the 2022 NATO Crisis

open access: yesPolicy &Internet, Volume 18, Issue 3, September 2026.
ABSTRACT Digital platforms are often theorized as universal drivers of political polarization, yet empirical patterns remain inconsistent across countries. Leveraging the natural‐experiment logic of Sweden's and Finland's simultaneous 2022 NATO applications and the NATO–Turkey diplomatic crisis, this study examines how national political cultures ...

Status and future of seed conservation of threatened plants in the post‐2020 era

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1763-1777, September 2026.
Ambitious targets have been set to backup seeds of threatened plants by the global strategy for plant conservation (GSPC), but it is unclear in how far these targets have been met and how seed collection should be organized to meet future challenges. Here, we provide an overview of the status of 44 countries in achieving seed conservation targets.

Reduced Expression of Magnesium Transport Proteins in the Distal Convoluted Tubule of Clcnkb‐Deficient Mice May Explain Urinary Magnesium Wasting in Classical Bartter Syndrome

open access: yesActa Physiologica, Volume 242, Issue 9, September 2026.
ABSTRACT Aim The kidney thick ascending limb (TAL) plays a key role in the transport of sodium, chloride, potassium, calcium, and magnesium. Bartter syndrome is a hypokalemic, salt‐losing tubulopathy caused by impaired TAL function. Pathogenic variants in SLC12A1 or KCNJ1 cause antenatal Bartter syndrome, and variants in CLCNKB result in classical ...
