TL;DR: A county-level 2026 study in PLOS One found that warmer monthly temperatures in the United States from 2013 to 2024 were associated with higher police-violence death rates, with projected additional deaths by 2050 under high-emissions climate scenarios. Key Findings 2013-2024 county-level data: Researchers linked U.S. police-violence deaths with monthly temperature and precipitation data across …
TL;DR: A 2025 systematic review in Translational Psychiatry found that substance use disorder was associated with recurring resting-state functional MRI (rs-fMRI), a scan of spontaneous brain-network communication, abnormalities in reward and self-control circuits across 53 studies. Key Findings 53-study meta-analysis: Researchers pooled whole-brain rs-fMRI studies covering 1,700 people with substance use disorder and 1,792 healthy …
TL;DR: A 2026 study in PLOS Medicine found that severe infections stayed linked to later dementia in Finland even after researchers accounted for a broad set of noninfectious comorbid diseases. Key Findings 62,555 dementia cases: The analysis matched Finnish adults diagnosed with late-onset dementia from 2017 to 2020 against 312,772 dementia-free controls. 29 prior hospital …
TL;DR: A 2026 medRxiv preprint on schizophrenia reported that illness insight tracked with resting-state functional MRI (fMRI) flexibility, a measure of how dynamically brain regions reconfigure their connectivity, and that these brain-dynamics patterns aligned with dopamine D2 and serotonin 5-HT2A receptor maps after accounting for antipsychotic receptor occupancy. Key Findings Two insight subtypes: Clinical clustering …
TL;DR: A 2026 systematic review and meta-analysis in Molecular Neurobiology found that plasma phosphorylated tau 217 (p-tau217), a blood marker of Alzheimer-linked tau pathology, identified biomarker-defined Alzheimer’s disease with pooled sensitivity of 85.4% and specificity of 88.0% across 27 studies. Key Findings 27-study evidence base: Researchers analyzed 19,652 participants from studies that compared plasma p-tau217 …
TL;DR: A 2026 study in Science of the Total Environment followed nearly 295,000 Southern California births and linked extreme nighttime heat in early and late pregnancy to higher autism diagnosis by age 5, while daytime heat was not associated. Key Findings A large Southern California cohort anchored the estimate: The retrospective Kaiser Permanente Southern California …
TL;DR: A 2026 medRxiv preprint tested SimulAD, an Alzheimer’s disease progression simulator, and reported that it reproduced mean amyloid-clearance results within 5% error across six major phase III anti-amyloid trials while also separating positive trials from null trials in retrospective power analyses. Key Findings Six phase III trials: Researchers retrospectively simulated TRAILBLAZER-ALZ2, CLARITY AD, EMERGE, …
TL;DR: A 2026 study in the Journal of Eating Disorders found that higher sensation seeking, a personality trait involving pursuit of novel or intense experiences, was linked to more restraint and overeating in 400 German adolescents, with stronger disordered-eating links in teens with higher BMI, hyperactivity/inattention, emotional symptoms, or peer problems. Key Findings 400 adolescents: …
TL;DR: A 2026 longitudinal study in Personality and Individual Differences followed 346 Turkish young adults across two survey waves three months apart and found that childhood psychological abuse predicted lower adult relationship satisfaction, with a reduced sense of belonging acting as the statistical mediator linking the early adversity to the later romantic outcome. Key Findings …
TL;DR: A 12-month four-wave longitudinal study in Psychological Science (N=2,149 adults across the UK, US, Canada, and Australia) found that feeling more emotionally isolated predicted higher chatbot use four months later — and that higher chatbot use, in turn, predicted further increases in emotional isolation at the next wave. Key Findings Bidirectional link with emotional …
