Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.

Cumulative Reproductive‐Lactation Burdens Induce a Systemic Immunometabolic Trade‐Off Between Milk Yield and Mammary Health of Dairy Cows

open access: yesAnimal Research and One Health, EarlyView.
A population‐scale longitudinal transcriptomic atlas reveals how lactation stage and parity reshape systemic gene regulation in dairy cows. Multiomics‐inspired analyses uncover dynamic immune and metabolic adaptations that contribute to reproductive longevity and sustained productivity across the bovine lifespan.

CASTOR1 Regulates Humoral Immune Responses and Contributes to the Pathogenesis of Systemic Lupus Erythematosus

open access: yesArthritis &Rheumatology, EarlyView.
Objective CASTOR1 senses arginine and regulates mammalian target of rapamycin complex 1 (mTORC1), a central metabolic signaling molecule. This study aimed to elucidate the roles of CASTOR1 in humoral immune responses. Methods We analyzed human B cell transcriptomes from healthy controls and patients with systemic lupus erythematosus (SLE) via ...
