Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

open access: yesJournal of Anatomy, Volume 247, Issue 3-4, Page 418-441, September/October 2025.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

The Vertebral Column of Flatfish: A Review

open access: yesReviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Flatfish (Pleuronectiformes) encompass fascinating fish species known for their high gastronomical value, rearing performances, and market prices, which attract both economic and scientific interest. Despite these attributes, flatfish exhibit unique morphological, developmental, and biological features, as well as distinctive swimming ...

Systematics of the Enigmatic Neotropical Rodent Genus Microakodontomys (Cricetidae: Sigmodontinae): New Evidence Supporting Its Distinctiveness and Endangered Status

open access: yesZoologica Scripta, Volume 54, Issue 5, Page 587-600, September 2025.
ABSTRACT The diversification of Neotropical sigmodontine rodents represents one of the most remarkable evolutionary events among mammals, encompassing numerous endemic, rare, and endangered genera and species. One of the most emblematic examples is Microakodontomys transitorius Hershkovitz 1993, originally described from a single specimen based on ...

Functional role and folding properties of the glucan‐binding domain of oral bacterial glucansucrase

open access: yesFEBS Letters, Volume 599, Issue 16, Page 2388-2402, August 2025.
The role of the glucan‐binding domain in Streptococcus sobrinus glucansucrase was examined, focusing on its impact on enzymatic activity, dextran binding, and structural stability of deletion mutants and a circularly permuted protein. Our research revealed that glucosyl transfer efficiency is linked to cooperative interdomain folding.

Growing Old at Tombos: A View of Older Adults in an Ancient Egyptian‐Nubian Community

open access: yesAmerican Journal of Biological Anthropology, Volume 187, Issue 4, August 2025.
ABSTRACT Objectives The experiences of older adults in ancient communities are often overlooked in studies due to many factors, such as preservation, methodological issues, and less frequent mention in available texts. Materials and Methods This study combines community‐ and individual‐level data to explore life for older adults at the ancient Egyptian/
