Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

Association of Clonal Hematopoiesis With Incident, Late‐Onset, Seropositive Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Clonal hematopoiesis (CH), defined by acquired driver mutations in hematopoietic stem cells, is associated with many inflammatory diseases of aging. We investigated whether CH and its subtypes, CH of indeterminate potential (CHIP) and mosaic chromosomal alteration (mCA), are associated with incident rheumatoid arthritis (RA) and whether ...

Dnmt3a Mutations Limit Normal and Autoreactive CD4+ T Follicular Helper Responses and Attenuate T Cell–Driven Joint Inflammation

open access: yesArthritis &Rheumatology, EarlyView.
Objective Somatic DNMT3A mutations are the most common drivers of clonal hematopoiesis in patients with rheumatoid arthritis (RA) and have been associated with seropositive disease and increased markers of inflammation. These mutations are predominantly hypomorphic or dominant‐negative, reducing DNMT3A function.

Reception Baseline Assessment and ‘small acts’ of micro‐resistance

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In September 2021, following the global COVID‐19 pandemic, the Department for Education introduced a national standardised digital Reception Baseline Assessment (RBA) for all English 4‐year‐old children. We analyse RBA and its associated Quality Monitoring Visits, as a further intensification of the new public management of early years ...

Case report: Deep sequencing and long-read genome sequencing refine prior genetic analyses in families with apparent gonadal mosaicism in PIK3CD-related activated PI3K delta syndrome

open access: yesFrontiers in Immunology
Gonadal and gonosomal mosaicism describe phenomena in which a seemingly healthy individual carries a genetic variant in a subset of their gonadal tissue or gonadal and somatic tissue(s), respectively, with risk of transmitting the variant to their ...

A mosaic of microclimates: biodiversity outcomes and wildlife habitat potential in large‐scale solar facilities

open access: yesBiological Reviews, EarlyView.
ABSTRACT The rapid global expansion of photovoltaic (PV) solar facilities, now comprising nearly 80% of the recent and projected growth of renewable electricity, represents one of the most significant land‐use changes of the 21st century. While PV facilities are critical for decarbonising energy systems, their large spatial footprint and infrastructure
