IntroductionEmotional maltreatment has been associated with problematic short-video use during adolescence, but the nature of this association remains unclear. This cross-sectional study examined the association between emotional maltreatment and problematic short-video use, estimated the indirect statistical association through narcissism, and tested whether physical activity moderated the direct association between emotional maltreatment and problematic short-video use.MethodsData were obtained in November 2025 from six schools across three Chinese provinces. The analytic sample included 1,622 adolescents, comprising 772 males and 850 females. Participants completed measures of emotional maltreatment, narcissism, problematic short-video use, and physical activity.ResultsEmotional maltreatment was positively associated with problematic short-video use, and an indirect statistical association was observed through narcissism. Physical activity moderated the direct association between emotional maltreatment and problematic short-video use, which was weaker at higher levels of physical activity.DiscussionConsidering a personality characteristic and a health-related behavior within the same model provides a broader understanding of the circumstances under which emotional maltreatment is associated with problematic short-video use. These findings may inform family- and school-based support concerning adolescents’ emotional needs, healthy short-video use, and regular physical activity.
Power without limits: exploring emotional regulation, moral authority, and psychiatric overreach through the Wizarding World of Harry Potter
BackgroundPsychiatry has never had more tools to relieve psychological suffering. Psychopharmacology, neuromodulation, early intervention, digital monitoring, and preventive approaches have expanded what clinicians can do. Yet this growing technical capacity also raises an uneasy question: when does care become control? Cultural narratives can offer spaces for examining such tensions, particularly when they dramatize power, vulnerability, suffering, and moral authority.AimThis narrative review uses the Wizarding World of Harry Potter as a conceptual lens to examine emotional regulation, moral authority, and psychiatric overreach, focusing on two contrasting figures: Lord Voldemort and Isidora Morganach.MethodsA theory-informed narrative review was conducted using a concept-focused analytic framework and structured conceptual synthesis. Literature was identified through focused searches in PubMed, PsycINFO, Scopus, and Google Scholar from database inception to June 2026, complemented by backward reference tracking. Sources covered Harry Potter scholarship, emotional regulation, psychological flexibility, narcissism and Dark Triad traits, medicalization, overdiagnosis, clinical ethics, and narrative medicine. To improve transparency, the synthesis distinguished direct literature on the Wizarding World from indirect psychiatric, psychological, ethical, and medical humanities scholarship used for conceptual interpretation.ResultsTwo pathways to psychiatric overreach and an intermediate zone of proportionate care were identified. The first, represented by Voldemort, involves destructive domination, emotional suppression, denial of vulnerability, instrumental use of others, and coercive authority. The second, represented by Isidora Morganach, involves hyper-compassionate control, intolerance of suffering, elimination of negative affect, moral certainty, and paternalistic intervention. Between these extremes, the intermediate zone emphasizes emotional integration, psychological flexibility, shared decision-making, contextual judgment, ethical proportionality, and clinical humility. Although one pathway is cruel and the other compassionate, both illustrate power exercised without sufficient emotional integration or ethical restraint.ConclusionBy exploring psychiatric questions through the Wizarding World, this review highlights how narrative frameworks can clarify the ethical boundaries of intervention. The central lesson is not that intervention is dangerous, but that intervention must remain proportionate, reflective, and ethically bounded. Psychiatry’s task is not to abolish all distress, but to relieve suffering while preserving autonomy, meaning, and human vulnerability.
Mental Illness Shows Context-Specific Genetic Effects
Many DNA variants linked with neuropsychiatric disorders (NPD) that do not code for proteins depend on neuronal activation, a study suggests.
The findings, in Science, highlight the power of cell stimulation to reveal context-specific “hidden” genetic effects in conditions such as schizophrenia.
They suggest that genetic regulation is not fully revealed by measuring gene expression alone.
Instead, gene activity—at least in the brain—may depend on context and the physiological state of neurons.
“Liang et al. demonstrate that the genetic processes that underlie neuropsychiatric disease are heavily determined by a dynamic physiological environment rather than by fixed cellular conditions,” said Biao Zheng, PhD, and Panos Roussos, PhD, from Icahn School of Medicine at Mount Sinai in New York, in a Perspective article accompanying the study.
They added: “To understand disease genetics, we might need to study the genome in motion and not at rest.”
Genome-wide association studies have revealed hundreds of genetic loci associated with mental illness, with more than 280 identified for schizophrenia alone.
But many of these DNA regions do not encode proteins and their impact is often subtle and difficult to detect.
To investigate further, Lifan Liang, PhD, from the University of Chicago, and co-workers studied gene expression and chromatin accessibility in single neurons derived from induced pluripotent stem cells collected from a hundred human donors.
The single-cell multi-omics study involved assessing transcriptional and epigenomic profiles before and after neurons were activated through potassium-induced depolarization.
The team found that much of the activity in regulatory DNA regions only became apparent with neuronal stimulation.
Both the number of detectable expression quantitative trait loci (eQTLs)—genetic variants associated with differences in gene expression—and chromatin accessibility QTLs (caQTLs)—DNA variants associated with differences in chromatin accessibility—rose after neuronal stimulation.
Shared and cell type-specific transcription factors worked together, possibly through regulatory cascades, to drive cell type-specific neuronal responses to stimuli.
eQTLs after stimulation had substantially weaker overlap with brain eQTL catalogs derived from postmortem tissue compared with eQTLs before stimulation.
This suggested that many relationships between regulatory DNA activity and gene expression become detectable only during neuronal activation and could be missed by traditional tissue-based studies.
A higher number of caQTLs were associated with neuropsychiatric disease compared with eQTLs, suggesting that disease-associated genetic variants could have detectable effects on regulatory DNA even when downstream changes in gene expression were not obvious.
Supporting this, chromatin accessibility and transcriptional responses to neuronal activation often occurred at different times.
Regulatory regions associated with genes that respond rapidly to neuronal stimulation often remained accessible after transcription subsided. By contrast, some late response genes exhibited accessible chromatin before their expression was induced.
When taken together, these observations implied that chromatin accessibility can be an indication of both prior and future transcriptional potential.
“We identified thousands of cell type–specific and activity-dependent quantitative trait loci for gene expression (eQTLs) and chromatin accessibility (caQTLs), helping prioritize NPD risk variants and genes that manifested functional effects only upon neuronal stimulation,” the researchers asserted.
They added: “Our work provides mechanistic insights on neuron subtype–specific activity-dependent gene regulation, substantially expanding the repertoire of context-specific causal variants and genes for NPD and other brain traits.”

When the market asks no price: AI chatbot interaction as psychic market disruption
The rapid adoption of AI chatbots for emotional support and quasi-therapeutic interaction raises questions that existing clinical and regulatory frameworks are not equipped to address. This Perspective applies the psychic arbitrage framework—which reconceptualizes defense mechanisms as energy-conversion operations on internal psychic markets—to analyze the specific transactional distortions produced by chatbot interaction. The framework identifies four dysfunctions: liquidity illusion (apparent emotional processing without genuine containment), market-making blockage (narcissistic reflection replacing transformative engagement), closure of arbitrage circuits (path-dependent externalization displacing autonomous elaboration), and repertoire degradation (progressive intolerance of costly but productive transactions). The article proposes that chatbots trained via Reinforcement Learning from Human Feedback (RLHF) produce a functional analogue of the Dark Triad profile—narcissistic mirroring, Machiavellian retention, and psychopathic detachment—as systematic architectural output regularities, not personality attribution. Preliminary converging evidence from mechanistic interpretability, formal reward-learning analysis, clinical reports, and user behavior studies is broadly consistent with these predictions but does not yet demonstrate direct long-term causal effects. The framework offers clinicians a transactional vocabulary for assessing AI-related risk and generates falsifiable predictions for future research.
