Disentangling Modulator and Fluoride Chemistry in Rare-Earth Metal–Organic Framework Formation via Multinuclear NMR Spectroscopy: A Mechanism-Guided Synthetic Redesign

Abstract Metal–organic framework (MOF) chemistry continues to expand, highlighting the need for molecular insight into framework formation. Solution-phase NMR provides a powerful, accessible, and economical means to probe these mechanisms. We examine the formation of rare-earth (...

Community Social Pediatrics in an Underserved Canadian City: Design and Early Outcomes of an Exploratory Pilot Study

Background: In Saint John, New Brunswick, nearly 1 in 3 children live in poverty, and the traditional pediatric care model is often ill-equipped to address the complex social realities that children experience. Community Social Pediatrics (CSP) is an interdisciplinary model that...

On the Discovery of the First Tetrapod Burrow from the Pennsylvanian-Age Clifton Formation, Stonehaven, New Brunswick, Canada

Reported trace fossils from the Clifton Formation, New Brunswick, Canada, are limited to a single occurrence of a temnospondyl trackway and invertebrate trackways identified in the Pennsylvanian continental strata. Our study builds on this with a description of a horizontal burro...

From concept to action: Driving impact through responsible research practices in the International Polar Year 2032–2033 An early career perspective

Regions at the poles are warming at rates two to four times higher than the global average, driving profound environmental, societal, and geopolitical changes. As Polar Early Career Researchers with careers extending into and beyond the 5th International Polar Year in 2032–2033,...

Psychometric Properties of the French Version of the Provider Co-Management Index-RN

Background Strengthening primary care through team-based models is a global priority as strong primary care systems are consistently associated with improved outcomes. The Provider Co-Management Index for Registered Nurses (PCMI-RN) is a validated instrument measuring co-manageme...

Sleep Healthy Using the Internet: A Meta-Analysis of Twenty Years of Research on a Digital Cognitive Behavioral Therapy for Insomnia Program

Abstract Study Objectives To summarize two decades of research on Sleep Healthy Using the Internet (SHUTi), among the most-studied digital Cognitive Behavioral Therapy for Insomnia programs. Methods PubMed, CINAHL, Web of Science, and PsycINFO were comprehensively searched throug...

Evaluating Kelp Feedstock for Alginate-Based Materials: Physicochemical Characterization of Sodium Alginate and Aquaculture Considerations

Abstract Cultivated kelps are a scalable marine feedstock for renewable polymers, but regional aquaculture supply chains lack engineering benchmarks for the alginate yield and quality. Here, we apply a lower-hazard citrate-based process to quantify bioplastics-relevant alginate m...

From genetics to migration: emerging insights into salmonid responses to environmental change from NoWPaS 2026

The International Workshop of PhDs and Post-doctoral Fellows on Anadromous Salmonids (NoWPaS) provides a platform for early-career researchers to present and discuss emerging research on salmonid biology. The 2026 meeting, held in Iceland, brought together contributions spanning...

Space-Time Waveform Relaxation Multigrid for Navier–Stokes

Abstract. Space-time finite-element discretizations are well-developed in many areas of science and engineering, but much work remains within the development of specialized solvers for the resulting linear and nonlinear systems. In this work, we consider the all-at-once solution...

Compounding Impacts—Genomic Exploration of the Potential Effect of Domestic Introgression on Climate Adaptation in Atlantic Salmon ( Salmo salar )

ABSTRACT Predicting population, species, and community responses to climate change is critical for the successful management of wild ecosystems. However, climate change does not act alone. Interactions among climate change and other anthropogenic threats could significantly compl...

Phylogeny and ecosystem jointly shape metabolite sensing by structured noncoding RNAs

Non-coding RNAs (ncRNAs) regulate gene expression through diverse structural and sequence-based mechanisms, often acting without protein intermediates. Riboswitches are cis-regulatory ncRNAs that directly sense small molecule metabolites to control gene expression. Many riboswitc...

Insights into the electrorheological and electrohydrodynamic regimes in electrically driven emulsions

Recently, we reported the electrorheoimaging technique [Bahraminasr and Yethiraj, Phys. Rev. Res. 8, 013231 (2026)] and found that the frequency-dependent electric field of an oil-in-oil emulsion yields two distinct regimes: a high-frequency dipolar, electrorheological (ER) regim...

Reconsidering the Alberta study of the closure of the Red Deer supervised consumption site

Supervised consumption sites (SCS) are interventions supported by decades of evidence and yet remain subject to considerable politicization. Recently, researchers from Alberta, Canada published a study in the journal Addiction that sought to assess the impacts of the closure of a...

Rapid arc-ophiolite formation during the Grampian-Taconic event: evolution of the Tyrone Igneous Complex, Northern Ireland

The Grampian-Taconic event of the broader Caledonian-Appalachian orogenic cycle records the accretion of oceanic tracts, arc terranes and microcontinental blocks the Laurentian margin during the early Palaeozoic. We present new field constraints, whole rock geochemistry, Sm-Nd is...

From Data-Model Fit to Model-World Fit: A Framework for Integrating Domain Knowledge into Artificial Intelligence

Machine-learning-based artificial intelligence (AI) systems often perform well in controlled settings but fail when deployed in the real world. These failures stem from a fundamental problem: ML/AI models optimize data-model fit by increasing statistical performance on training d...

A unifying theory for the evaluation of conditional Akaike information for mixed-effects models

{Simulation studies are conducted to assess the accuracy of our method for evaluating the conditional AIC and its model selection performance across a wide range of mixed-effects models. The proposed approach provides a valuable tool for model selection in the context of mixed-ef...

Trends in opioid containing drug seizures described as pills between 2020 and 2024 in Canada

People who use drugs may access prescription opioids from unregulated markets to avoid fentanyl and lower toxicity risk, though concerns regarding counterfeit pills have emerged. To better understand the composition of pills that may be circulating in the unregulated drug supply,...

Redesigning 9-1-1 Paramedic Pathways: Evaluation of the IMPACC Model of Care

OBJECTIVES Paramedic services remain organized around rapid response, time-sensitive events, and hospital conveyance despite increasing 9-1-1 use for lower-acuity and undifferentiated presentations. There is a need to improve the alignment of paramedic services for patients seeki...

The psychosocial impact of neurofibromatosis type 1: a narrative review

Abstract Neurofibromatosis type 1 (NF1) is a rare autosomal dominant (AD) genodermatosis characterized by café-au-lait macules (CALMs), cutaneous and plexiform neurofibromas, and cognitive impairments and neurodevelopmental disorders. As a rare genetic skin disease (RGSD), NF1 is...

Sex & Gender Science: integrating the social with the biological

Abstract For decades, researchers have largely studied aspects of sex and gender separately; the former as a basic science and the latter as a social construct with real world consequences, including health inequities. In recent years, as our collective understanding of how the b...
