The status of thegn in late Anglo‐Saxon England

Early Medieval Europe, Volume 34, Issue 2, Page 323-352, May 2026.
This article considers how the term ‘thegn’ was used in tenth‐ and eleventh‐century England. Although commonly thought to indicate members of a face‐to‐face service aristocracy with specific attributes, it has resisted close definition. Examination of references to anonymous thegns in administrative and legal texts suggests that the people meant were ...

Coronavirus Detection in Bats Captured on the Deforestation Arc of Mato Grosso, Brazil

Zoonoses and Public Health, Volume 73, Issue 3, Page 281-287, May 2026.
ABSTRACT Coronaviruses (CoV) are RNA viruses associated with enteric and respiratory diseases and known for their emergence potential in humans and other mammals. CoVs originate from zoonotic transmission, in which bats are natural reservoirs. Previous studies suggest that CoV diversity is positively correlated with bat diversity, whereas anthropogenic
