Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

An energy‐based aggregate stability method is more management‐sensitive than commercial methods in coarse‐textured, subtropical orchard soils

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Aggregate stability impacts important soil functions, including carbon/water storage and soil structure. Macroaggregate stability tests, using rainfall simulation or wet sieving, are commonly used, but microaggregate stability tests may be more applicable to subtropical, coarse‐textured soils.

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

Binary Active Sites Construction of More Stable and Higher Dispersed Mn‐Doped CuOx/CeO2 Catalysts via Ethylene Glycol‐Assisted Impregnation for Highly Efficient CO Oxidation

cMat, Volume 3, Issue 2, June 2026.
ABSTRACT The copper–cerium catalyst has shown brilliant performance in catalytic CO oxidation at low temperatures. However, the current research focus is needed to comprehensively understand the impact of doped elements and metal species content on the structure and performance of the catalysts.
