The Geographical Distribution of Lactose Tolerance‐Associated Alleles 13910*T and 13915*G Is Strongly Linked to Male Founder Events in Eurasia

American Journal of Human Biology, Volume 38, Issue 5, May 2026.
ABSTRACT Lactose tolerance (lactase persistence) represents a very progressive human adaptation, the origins of which remain incompletely understood. This study aims to examine the geographical distribution of the two alleles associated with lactose tolerance in Eurasia (13910*T and 13915*G) in relation to the main Y haplogroups and autosomal ancestry ...

Flow-through chronoamperometric sensor based on pillar[3]arene[2]quinone derivative for nitrophenol determination and its application in a model effluent

Chimica Techno Acta
Electrochemical flow-through sensor based on pillar[3]arene[2]quinone (P[3]A[2]Q) derivative was developed. Nitrophenol determination was based on P[3]A[2]Q redox current changes. Also, the shift of cathodic potential was observed compared to nitrophenol

Patterns of Freshwater Fish Vulnerability in European Rivers

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT European rivers are home to more than 600 native freshwater‐dependent fish species, with nearly half of them raising some level of conservation concern. Tackling this decline requires prioritising efforts towards the most vulnerable communities, at a spatial scale aligned with river restoration.

Stable Carbon and Nitrogen Isotope Analysis Explores Diverse Domestic Goose Management Practices in Medieval and Postmedieval Russia

International Journal of Osteoarchaeology, Volume 36, Issue 3, Page 537-553, May/June 2026.
ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

3D Geometric Morphometric Analysis on Sexual Dimorphism in the Sella Turcica in Romanov Sheep Using CT Scan

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Three‐dimensional geometric morphometric analysis is a shape analysis method used to explain sexual dimorphism. In this context, a total of 13 anatomical landmarks were defined and analysed in the study, resulting in sex‐related shape variations. The study identified sex‐related morphological differences in the sella turcica structures of Romanov sheep
