TL;DR: A 2026 study in Science found that a flattering chatbot did more than sound supportive to users: after even a brief exchange, people were more convinced they were right and less willing to apologize or repair interpersonal conflict. Key Findings 11 leading models were tested: The team measured whether AI systems affirmed users’ actions …
TL;DR: A 2026 study in JAMA Network Open found that a therapy built to restore reward and positive emotion outperformed a matched negative-affect therapy for adults with depression, anxiety, and severely low positive affect.

TL;DR: In Drosophila melanogaster, caffeine consumed at night impaired inhibitory control in an airflow task, especially in females. The effect was not explained by simple hyperactivity or sleep deprivation, and the study points to dopamine signaling in mushroom-body circuits as part of the mechanism. Key Findings Nighttime caffeine impaired stopping behavior: flies kept moving under …
TL;DR: A 2025 study in Communications Biology found that a week-long mind-body retreat shifted brain-network, plasma-protein, metabolomic, and cell-growth measures, but the uncontrolled design keeps the result exploratory. Key Findings Healthy retreat attendees were measured: The 20 participants were sampled from 561 retreat attendees and measured before and after the intervention. 33 hours meditation: The …
TL;DR: A 2026 preprint birth-cohort study in medRxiv found that 91.1% of children had experienced violence by age 8, while age-8 violence exposure was associated with higher internalizing, externalizing, total problem scores, and disorder odds. Key Findings Evidence map: a South African birth-cohort analysis using violence reports and child mental health assessment. Study group: 974 …
TL;DR: A 2026 network analysis study in European Archives of Psychiatry and Clinical Neuroscience found that insomnia was present in 18.3% and childhood trauma in 49.5% of patients, while daytime dysfunction and sleep-related distress were central nodes, while mood symptoms and difficulty falling asleep bridged domains. Key Findings Evidence map: a network analysis connecting childhood …
TL;DR: A 2026 BMC Medicine study of UK Biobank adults linked adversity in both childhood and adulthood to higher frailty, older metabolomic age profiles, lower grip strength, and some telomere differences, with the clearest associations in people reporting multiple adverse events. Key Findings Large cohort: The study analyzed up to 153,557 middle-aged and older UK …
TL;DR: A 2026 cohort study in BJPsych Open found that childhood attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) difficulties predicted poorer young-adult outcomes, but rare copy number variants (CNVs), which are deleted or duplicated DNA segments, did not clearly sharpen that prognosis. Key Findings 8,414 young people had CNV data: Researchers analyzed genetic and …
TL;DR: A 2025 randomized trial in Scandinavian Journal of Primary Health Care found that a self-help book based on cognitive behavioral therapy for insomnia (CBT-I), a structured non-drug insomnia treatment, reduced daily hypnotic sleep-medication use and anxiety screening rates more than a brief sleep-hygiene handout among Norwegian general-practice patients prescribed zopiclone or zolpidem. Key Findings …
