Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

Land Degradation &Development, Volume 37, Issue 13, Page 9038-9052, 15 August 2026.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

Technical note: Comparison of radiometric techniques for estimating recent organic carbon sequestration rates in inland wetland soils [PDF]

Biogeosciences
For wetlands to serve as natural climate solutions, accurate estimates of organic carbon (OC) sequestration rates in wetland sediments are needed. Dating using cesium-137 (137Cs) and lead-210 (210Pb) radioisotopes is commonly used for measuring OC ...

Supramolecular Coordination Platforms for Smart Theranostics: Leveraging the Dynamic Molecular Networks of Metal–Polyphenol Assemblies

Aggregate, Volume 7, Issue 7, July 2026.
In this review, we summarize the recent developments of metal–polyphenol networks (MPNs) as a highly versatile and functionally integrated supramolecular assembly platform. We also discuss their pivotal role in steering biomedical materials away from conventional single‐function designs and toward intelligent, unified diagnostic and therapeutic ...

[The role of individual segments of the gastrointestinal tract in the elimination of cesium radioisotopes].

Roczniki Panstwowego Zakladu Higieny, 1992
The transfer of radiocesium from blood to the lumen of individual sections of the gastro-intestinal tract was quantitatively determined. The water suspension of ion exchange resin was injected to the lumen of the individual sections of the gastro-intestinal tract. The sections were ligated. The highest amount of radiocesium absorbed to the resin in the

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...
