Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

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

open access: yesBoreas, 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 ...

Vapor‐Phase Grain‐Boundary Anchoring Enables Molecular Toughening and Record Bending Endurance in Pilot‐Scale Roll‐to‐Roll‐Printed Flexible Perovskite Modules

open access: yesAngewandte Chemie, Volume 138, Issue 30, 20 July 2026.
A vapor‐phase molecular toughening strategy is developed for pilot‐scale roll‐to‐roll (R2R) ‐compatible fabrication of flexible perovskite solar modules. Thiol vapor selectively regulates crystallization and anchors at grain boundaries, reducing defects while enhancing mechanical resilience.

Differential growth dynamics of common salt marsh species Spartina alterniflora and Juncus roemerianus under varied sediment amendments

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Many coastal wetlands are at high risk of degradation or loss due to sea‐level rise. Restoration techniques for maintaining coastal marshes are paramount, with thin‐layer placement (TLP) emerging as one feasible solution. Despite TLP's utilization, additional research is needed on species‐ and sediment‐specific responses ...

High‐Throughput Sequencing in Aquaculture Disease Investigations: Challenges and Opportunities for Implementation

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT The current generation of sequencing technologies can produce terabases of data with exceptional accuracy and speed, at a fraction of the cost of older methods. Despite this unprecedented power, adoption into aquaculture health management presents several challenges, including identifying where such capability may be optimally deployed.
