Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Musashi‐1 Drives Radioresistance and Stemness in Head and Neck Squamous Cell Carcinoma via a Radioresistant FaDu Model

Cancer Science, EarlyView.
Fractionated irradiation generated radioresistant F‐IRR cells with enhanced CSC properties despite slower proliferation. MSI1 was strongly upregulated and functionally promoted stemness, tumorigenicity, and radiation resistance. JNK signaling acted upstream of MSI1, while JNK inhibition suppressed these malignant traits, identifying the JNK–MSI1 axis ...

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands

Water and Environment Journal, EarlyView.
ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

137Cs tracing of the spatial patterns in soil redistribution, organic carbon and total nitrogen in the southeastern Tibetan Plateau

International Soil and Water Conservation Research, 2023
The southeastern Tibetan Plateau, which profoundly affects East Asia by helping to maintain the stability of climate systems, biological diversity and clean water, is one of the regions most vulnerable to water erosion, wind erosion, tillage erosion ...

Specific Position of Halogen in Crystalline TADF Scintillators Enables Efficient Triplet Harvesting Through Vibrational Modulation of Spin–Orbit Coupling

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
Specific ortho‐halogenation transforms crystalline TADF emitters into efficient organic scintillators. Fluorine reduces the effective singlet–triplet separation, while chlorine combines near‐degenerate excited states with vibrational modulation of spin–orbit coupling.

Phytoextraction of 137Cs: The Effect of Soil 137Cs Concentration on 137Cs Uptake by Beta vulgaris

, 2002
The last phase for MAGNOX ELECTRIC plc's reactor decommissioning strategy is site clearance and delicencing. Phytoextraction of 137Cs may be able to assist in meeting this objective.

Evaluation of bioavailable 137Cs transfer from forest litter to Scarabaeidae beetle (Protaetia orientalis) through a breeding experiment in Fukuhshima.

PLoS ONE
Following the Fukushima Daiichi Nuclear Power Plant accident in 2011, most of the released 137Cs remained in the litter and surface soil of the adjacent forest floor.

Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...
