Fossil denticles reveal how ocean productivity shapes shark baselines and recovery potential

Shark populations on coral reefs have declined globally, but few baselines exist to quantify natural variability before human impact. Using fossil dermal denticles preserved in reef sediments, we reconstructed shark communities across the Isthmus of Panama before substantial expl...

Leadership for climate-resilient healthcare: insights from an ATACH technical meeting

Introduction Climate change is increasingly recognised as both a public health emergency and a systemic stressor on healthcare systems. While many healthcare organisations have articulated ambitious climate and sustainability commitments, progress is frequently constrained by gap...

Temporal Feature Interaction for Robust Remote Sensing Image Change Detection: A Taxonomy and Cross-Domain Comparative Study

Remote sensing change detection (RSCD) has advanced through convolutional, attention-based, transformer, and hybrid architectures, yet models are commonly compared as whole architectural families rather than by how their temporal streams interact. This study introduces the Tempor...

Representation as intervention: A reply to Unal, Polillo, Caliskan, and MacKenzie

Abstract In their article ‘The modes of performativity’, Unal et al. (2025) argue that the concept of ‘representational interventions’ provides a basis for a meta-theoretical framework through which to understand the performativity literature. Building on a previously published a...

Early‐Life Dietary Protein Source Reshapes Gut Microbiota but Fails to Curtail Diet‐Induced Metabolic Syndrome in Young Rats

OBJECTIVE: Dairy consumption plays a protective role in obesity that may be mediated through the gut microbiota. This study examined the role of dairy proteins, casein, whey, and complete dairy (skim milk powder), and a plant-based alternative, soy, on gut microbiota composition,...

Chronic Mild Circadian Disruption Alters Anxiety-Like Behavior and Spatial Navigation in Adult Mice

Sleep and circadian disruption adversely impacts mental health and physiology. Such disruption varies in degree and emerges from numerous causes, ranging from severe disruption arising from rotating shift work or frequent jetlag to more mild circadian stress experienced by people...

Youth experiences and preferences for sexual health education and digital support: a community-based qualitative study

BACKGROUND: Many adolescents rely on digital sources for sexual and reproductive health (SRH) information; yet, online content is often inconsistent, inaccurate, or difficult to interpret. Digital knowledge translation strategies offer promising approaches to deliver accessible a...

Microheterogeneityand Ion Clustering in Aqueous PotassiumDihydrogen Phosphate Solutions

Abstract The molecular-scale organization in concentrated aqueous potassium dihydrogen phosphate solutions may play a critical role in their behavior, such as in the structural processes that precede crystal nucleation. In this work, molecular dynamics simulations are used to inv...

Comparative Transcriptomic Analysis of Neurodegeneration and Viral Infection: A Multi-Method Validation Framework

AbstractParkinson's disease and influenza virus infection present with entirely different clinical pictures, yet both have been linked to shared inflammatory and neuroimmune mechanisms, an interest dating back to post-encephalitic parkinsonism following the 1918 influenza pandemi...

Right hippocampal volume and attenuated psychotic symptoms distinguish subgroups of youth with common patterns of temporoparietal effective connectivity

Abstract Associations between patterns of brain connectivity and brain structural features have transdiagnostic relevance to psychopathology. There is considerable evidence for disruptions to the hippocampus and temporoparietal brain systems in psychotic disorders. The present st...

Polysaccharide coatings unlock high-performance TiO2 UV filters for sunscreen formulations

Designing mineral ultraviolet (UV) filters that combine strong UV absorption and photostability remains an open challenge. Conventional silica coatings only partially mitigate the photocatalytic activity of titanium dioxide (TiO2) and rely on energy-intensive synthesis. Here, we...

Embodiment Envelopes: Calibrating Agency-Constrained Shared Autonomy in VR to Transfer to Wearable Prosthetic Augmentation

How can virtual studies of augmented body parts translate into wearable robotic augmentation with predictable embodiment outcomes? We propose Embodiment Envelopes: user-centered feasible action sets that bound how far shared autonomy may deviate from the user’s inferred intent. T...

Patient-physician sex concordance and real-world disparities in cancer treatment practices and outcomes in medical oncology

The impact of sex inequities in healthcare may be magnified in medical oncology, where patients and physicians often navigate life-limiting illnesses and intensive treatments. We examined the associations among patient-physician sex concordance, treatment practices, and cancer ou...

Recent lifestyle change impacts sleep and circadian rhythms among the Indigenous peoples of Peninsular Malaysia

ABSTRACT Sleep disorders are rising globally, but their lifestyle causes remain unclear. We recorded sleep-wake patterns via actigraphy from 1036 Orang Asli adults across 12 communities in Peninsular Malaysia undergoing market integration, marked by changes in permanent infrastru...

Transcranial ultrasound stimulation of the subthalamic nucleus modulates cognitive function in humans

Transcranial ultrasound stimulation (TUS) is an emerging neuromodulation technique that can target subcortical structures with high precision. Previous research has reported basic behavioural changes with TUS; however, the capacity of TUS to modulate higher-order cognitive functi...

Protective Role of Donor KIR B Haplotype in Cytomegalovirus Reactivation Following T-Cell-Depleted Hematopoietic Stem Cell Transplantation

Background: Cytomegalovirus (CMV) reactivation is a major complication after hematopoietic stem cell transplantation (HSCT). Natural killer (NK) cells help control CMV through killer-cell immunoglobulin-like receptors (KIRs) and their HLA ligands, but donor-derived CMV-specific T...

Endovascular Thrombectomy for Cerebral Venous Thrombosis: Current Status and Future Directions

Abstract Cerebral venous thrombosis (CVT) represents a relatively rare cause of stroke, yet it carries an overall rate of death or dependency of up to 15%. The mainstay of its management is therapeutic anticoagulation, either subcutaneously or intravenously in the acute phase, fo...

Frailty and Surgical Invasiveness Are Independently Associated with Complications in Pediatric Spinal Deformity Surgery

Background: The purposes of this study were to determine whether frailty and surgical invasiveness are independently associated with perioperative outcomes and to describe the outcome rates when these 2 risk domains are considered together in pediatric patients undergoing spinal...

Prognostic Stratification of Brain Metastases from Nonanaplastic Follicular Cell–Derived Thyroid Carcinoma: Results of an International Multicenter Retrospective Study

Background: Brain metastases (BMs) from nonanaplastic follicular cell–derived thyroid carcinoma (hereinafter referred to as non-ATC) are rare and not well characterized, with limited evidence guiding treatment and prognostic stratification. We aimed to describe clinical features,...

A Novel Approach to Characterizing Patterns of Real-World Upper-Extremity Use During Walking and Activities of Daily Living in People with Subacute Stroke

In accelerometer-based measurement, the inclusion of upper extremity (UE) activity during walking can overestimate real-world functional UE use in people post-stroke. This study introduces a comprehensive, accelerometer-based approach to examining real-world UE use, including the...
