Moral Disengagement and Unethical Generative AI Use as the Chain Mediators Between Antagonistic Personality and Problematic Generative AI Use

Kağan Kırcaburun, Pınar Özdemir · 2026 · Behavioral Sciences

The rapid integration of generative artificial intelligence (GAI) tools into academic and professional contexts has raised concerns regarding unethical use and the potential development of problematic usage patterns. Drawing on personality and moral psychology frameworks, the present study examined the associations between antagonistic personality traits (narcissism, Machiavellianism, and psychopathy) and problematic (i.e., addictive) GAI use (PGAIU), as well as the chain mediating effect of moral disengagement and unethical GAI use (UGAIU). Data were collected from an adult sample (N = 491; 5

A dynamic bidirectional system of perceived teacher boredom, language learners’ boredom, and L2 writing motivation: a feedback loop system

Mehdi Solhi, Majid Elahi Shirvan, Tahereh Taherian · 2026 · Asian-Pacific Journal of Second and Foreign Language Education

Abstract The dynamic and reciprocal nature of boredom and motivation in L2 classrooms remains underexplored and little is known about how L2 teachers’ perceived boredom (PTB), foreign language learning boredom (FLB), and L2 writing motivation (WM) evolve within and across individuals over time, particularly from a dynamic systems perspective. A total of 264 English as a foreign language (EFL) learners and 21 teachers participated, and data were collected using a 10-day experience sampling approach. We specifically examined three feedback loops—PTB-FLB, FLB-WM, and PTB-WM. Dynamic structural eq

Metabolic anomalies in vitiligo: a new frontier for drug repurposing strategies

Alessia Paganelli, Federica Papaccio, Mauro Picardo et al. · 2025 · Frontiers in Pharmacology

Vitiligo is a chronic autoimmune condition characterized by the destruction of melanocytes, leading to patchy loss of skin depigmentation. Although its precise cause remains unclear, recent evidence suggests that metabolic disturbances, particularly oxidative stress and mitochondrial dysfunction, may play a significant role in the pathogenesis of the disease. Oxidative stress is thought to damage melanocytes and trigger inflammatory responses, culminating in melanocyte immune-mediate destruction. Additionally, patients with vitiligo often exhibit extra-cutaneous metabolic abnormalities such as

Gut‒heart axis: emerging therapies targeting trimethylamine N-oxide production

Efrain Ricardo Torres, Jennifer Wilcox, W. H. Wilson Tang · 2025 · Gut Microbes

Trimethylamine N-oxide (TMAO) has garnered considerable attention because of its role in the pathophysiology and pathogenesis of various disorders, particularly heart and kidney disease. Gut microbes produce trimethylamine (TMA) moieties from common dietary precursors, such as choline or carnitine, which are subsequently metabolized by the liver into TMAO. Circulating TMAO then exerts various effects, influencing dyslipidemia, metabolic syndrome, endothelial dysfunction, and inflammation, as well as other detrimental processes. Many existing medications have been shown to decrease TMAO levels

Confounding factors and biases abound when predicting molecular biomarkers from histological images

Muhammad Dawood, Kim Branson, Sabine Tejpar et al. · 2026 · Nature Biomedical Engineering

Deep learning models that infer clinically relevant biomarker status from tissue images are being explored as rapid and low-cost alternatives to molecular testing. Here we show, through statistical analysis across multiple cancer types, datasets and modelling approaches, that the datasets used to train these models contain strong dependencies between biomarkers and clinicopathological features, which prevent models from isolating the effect of a single biomarker and lead them to learn confounded signals. Consequently, their prediction accuracy varies substantially with the status of codependen

Integration of plasma eMTBR-tau243 and p-tau217 in the diagnosis and stratification of Alzheimer's disease: a prospective cohort study

Niklas Mattsson-Carlgren, Sebastian Palmqvist, Kanta Horie et al. · 2026 · The Lancet Neurology

BACKGROUND: Alzheimer's disease pathology can be accurately identified with blood biomarkers (core 1 biomarkers), including plasma p-tau217 tests. Biomarkers that change longitudinally after diagnosis (core 2 biomarkers) can increase confidence that Alzheimer's disease pathology is contributing to cognitive symptoms. Plasma eMTBR-tau243 reflects tau tangle pathology and is a promising core 2 biomarker. We aimed to examine whether, among patients positive for plasma p-tau217, plasma eMTBR-tau243 improves classification of established Alzheimer's disease and predicts cognitive decline and tau ta

Human microglial transitions at the Aβ–tau inflection point associate with divergent pathways to dementia and resilience

Ashley Lu, Wei-Ting Chen, Maria Dalby et al. · 2026 · Nature Medicine

Alzheimer's disease (AD) is not an inevitable outcome of pathology but a dynamic process shaped by how brain cells respond to amyloid-β (Aβ) and tau. To disentangle these responses, we combined spatial transcriptomics and single-nucleus RNA sequencing of the superior frontal cortex from octogenarians living with or without dementia and from cognitively intact centenarians with comparable Aβ accumulation. We identified six distinct tissue domains representing a spatial pathological continuum of AD, with a key inflection point marked by a shift from Aβ-associated inflammatory changes to tau-asso

Examining human reliance on artificial intelligence in decision making

Jo Pearson, Itiel E. Dror, Emma Jayes et al. · 2026 · Scientific Reports

The use of Artificial Intelligence (AI) to effectively support human decision making depends on whether humans are willing to trust in, and thus rely on, AI. Understanding human reliance on AI is critical given controversial reports of AI inaccuracy and bias. Furthermore, the erroneous belief that using technology removes biases may lead to overreliance on AI. To examine humans’ reliance on AI, human participants (N = 295, Mage = 33.79) judged the authenticity of 80 faces (40 real, 40 AI-synthesized) presented alongside guidance supposedly from humans or from AI. This guidance was correct only
