Low Climate Benefit of Nordic Coastal Marshes: Site Conditions Outweigh Grazing Effects and Shape Trade‐Offs Between Carbon Storage and Its Stability

Global Change Biology, Volume 32, Issue 5, May 2026.
Conceptual diagram of soil carbon cycling across climatic and environmental gradients in Nordic marshes and grazing effect. Denmark's warmer climate, high nutrient inputs, elevated salinity, and sandy soils promote rapid microbial decomposition of predominantly labile and root‐derived OC, driving high CO2 emissions and relatively high although unstable

Organic Carbon Burial Rates in Muddy Temperate Shelf Sea Sediments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Muddy continental shelf sediments act as important sinks for atmospheric CO2 by accumulating organic matter, a small fraction of which is buried and stored as organic carbon (OC) over long timescales. Quantifying long‐term OC burial in shelf sediments is critical for understanding their role in climate regulation; however, this remains ...

Determinación de polonio-210 (210Po) en alimentos y agua: una revisión (2014-2019)

Revista Investigaciones y Aplicaciones Nucleares, 2021
El polonio-210 (210Po) es uno de los radionúclidos que genera mayor preocupación debido a su radiotoxicidad. La mayoría del 210Po que se encuentra en nuestro entorno se produce de forma natural y su distribución ambiental es el resultado de dos procesos

Pan‐Arctic Peatlands Have Expanded During Recent Warming

Global Change Biology, Volume 32, Issue 2, February 2026.
Arctic peatland carbon is important because it represents a large carbon stock that may be vulnerable to climate change. This work explores the expansion and/or shrinkage of Arctic peatlands using observations in two north–south transects in Canada and in Europe.

Astatine‐211—Towards In Vivo Stable Astatine‐211 Labeled Radiopharmaceuticals and Their (Pre)Clinical Applications

Medicinal Research Reviews, Volume 46, Issue 1, Page 203-237, January 2026.
ABSTRACT Targeted radioligand therapy has emerged as a promising treatment option for eradicating advanced cancer forms. α‐Emitters are considered particularly promising as they can obliterate (micro)‐metastases. The α‐emitter astatine‐211 (211At) has experienced increased interest due to its favorable decay properties.

Effects of Solid–Liquid Partition Coefficients and Soil Properties on the Transfer of Natural Radionuclides (238U, 226Ra, and 210Po) to Water Spinach (Ipomoea aquatica)

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Solid–liquid partition coefficient (Kd) and soil‐to‐plant transfer factor (TF) are two important parameters in numerical models for predicting radionuclide availability in plants. They have implications for agricultural strategies in high‐background radiation areas, where the activity concentrations of naturally occurring radionuclides (NORs) are ...
