Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, Volume 41, Issue 4, Page 645-659, May 2026.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

Eicosapentaenoic and Docosahexaenoic Acid Levels in Mouse Tissues After Intake of Echium and Ahiflower Oils Rich in Stearidonic and α‐Linolenic Acids

Lipids, Volume 61, Issue 3, Page 417-426, May 2026.
Dietary supplementation with stearidonic acid–rich Echium and Ahiflower oils increases EPA levels across multiple mouse tissues, while DHA responses remain tissue‐specific and limited, supporting the strategic use of plant‐based omega‐3 sources for EPA‐focused interventions. ABSTRACT Omega‐3 fatty acids (n‐3 FA), particularly eicosapentaenoic acid (EPA)

Fluvial connectivity drives carbon cycle dynamics in a tropical mega‐delta

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Coastal estuaries are hotspots of biogeochemical cycling, biodiversity, and sediment processing, yet the drivers of carbon cycle processes remain poorly constrained. Here, we elucidate the influence of hydrological connectivity on carbon biogeochemistry in the Indian Sundarban over successive monsoon seasons by comparing hydrologically ...

Azole antifungal contaminants disrupt mycorrhizal function and risk agricultural sustainability

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 952-964, May 2026.
Global food production is increasingly threatened by soil degradation, climate change and the rising costs of synthetic fertilisers. Circular agriculture, which promotes resource reuse, is a promising solution, but using treated wastewater and biosolids in farming introduces risks from emerging contaminants like pharmaceutical residues.

From Fjord to Shelf: Drivers of Organic Carbon Transformation and Storage Across Connected Marine Sedimentary Systems

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract Continental shelf sediments play a key role in the global carbon cycle through the long‐term storage of organic carbon (OC). However, outside of a few continental shelves dominated by large rivers our understanding of the mechanisms that drive the remineralization, burial and storage of OC across these sedimentary systems is underdeveloped.
