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, EarlyView.
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.

Osteohistological analysis of metatarsals reveals new information on pathology and life history of troodontids from the Campanian Dinosaur Park Formation, Alberta, Canada

open access: yesJournal of Anatomy, EarlyView.
A histological survey of troodontid metatarsals from the Dinosaur Park Formation (DPF) was conducted, revealing correlates for stresses in the troodontid arctometatarsus and providing the first histological assessment of pathologies for this taxon.

From leprosy to ground zero: Imagining futures in a world of elimination

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract Achieving a target of zero—zero disease, zero disability, and zero discrimination—has become the dominant focus of campaigns to control or eliminate diseases, from HIV/AIDS to malaria to leprosy. Given the historical failure of most eradication programs over the last century, such teleological imaginings of disease‐free futures might seem ...

Changes in Claw Shape and Load after Hoof Trimming in Dairy Cattle Housed in a Free Stall System

open access: yesNihon Chikusan Gakkaiho, 2005
乾乳期間中の乳牛49頭(初産19頭,2産14頭,3産以上16頭)に対して,分娩前2ヵ月で削蹄を行い,以降1ヵ月間隔で4ヵ月間に渡り前・後肢蹄形状,蹄角質硬度および蹄球糜爛スコアを調査した.供試牛は乾乳期間中には屋外パドック,分娩後1週からはフリーストール牛舎で飼養されていた.また,削蹄直後と削蹄後4ヵ月では前・後肢内・外蹄荷重を計測した.削蹄後2ヵ月で後肢外蹄蹄踵高が有意(P<0.05)に増加,前・後肢内蹄蹄尖角度が有意(P<0.05)に減少し,削蹄後3~4ヵ月で外蹄に対する内蹄負面面積の割合は後肢では有意(P<0.05)に減少したが,前肢では有意な変化は認められなかった.削蹄後4ヵ月で外蹄に対する内蹄の荷重割合は後肢では有意(P<0.05)に減少し,前肢では有意(P<0.05)に増加した ...

Mating system variation and gene expression in the male reproductive tract of Peromyscus mice

open access: yesMolecular Ecology, EarlyView.
Abstract Genes involved in reproduction often evolve rapidly at the sequence level due to postcopulatory sexual selection (PCSS) driven by male–male competition and male–female sexual conflict, but the impact of PCSS on gene expression has been under‐explored.

How good are large language models at product risk assessment?

open access: yesRisk Analysis, Volume 45, Issue 4, Page 766-789, April 2025.
Abstract Product safety professionals must assess the risks to consumers associated with the foreseeable uses and misuses of products. In this study, we investigate the utility of generative artificial intelligence (AI), specifically large language models (LLMs) such as ChatGPT, across a number of tasks involved in the product risk assessment process ...

Climate Poetics: Contemporary Ecopoetry and the Remaking of Elegy

open access: yesFuture Humanities, Volume 3, Issue 2, November 2025.
ABSTRACT One manifestation of the cascading ecological crises that characterize our current moment is a weakening of any sense of futurity. The implacable escalation of the climate crisis, the amplification of which is already inevitable given the carbon already in the atmosphere, has the effect of eroding any forward‐facing enterprise and ...

Three‐Dimensional Limb Kinematics in Brown‐Throated Three‐Toed Sloths (Bradypus variegatus) During Suspensory Quadrupedal Locomotion

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 5, Page 564-577, June 2025.
ABSTRACT Suspensory locomotion differs significantly from upright quadrupedal locomotion in mammals. Nevertheless, we know little concerning joint kinematics of suspensory movement. Here, we report three‐dimensional kinematic data during locomotion in brown‐throated three‐toed sloths (Bradypus variegatus). Individuals were recorded with four calibrated

Physical Impairments in People With Gout: A Scoping Review

open access: yesMusculoskeletal Care, Volume 23, Issue 2, June 2025.
ABSTRACT Introduction Gout is the most common form of inflammatory arthritis. It is predominantly managed with pharmacological interventions, and physical impairments in people with gout have seldom been studied. We aimed to identify gout‐related physical impairments that may be targeted by physical interventions.

The SG‐Climbot: An Adaptable, Efficient, Inspection and Repair Robot for Steam Generator Heat Transfer Tube Sheet

open access: yesJournal of Field Robotics, Volume 42, Issue 4, Page 1080-1102, June 2025.
ABSTRACT The steam generator plays a crucial role as a safety component and protective barrier in nuclear power plants. Regular inspection and repair of heat transfer tubes, which operate in high‐temperature, high‐pressure, corrosive, and abrasive environments for extended periods, are essential.
