AI-Assisted Bayesian Inference Found Gamma-Secretase Alzheimer Pathways

TL;DR: A 2026 medRxiv preprint applied ChatGPT-4o-assisted Bayesian-frequentist hybrid inference to Alzheimer’s single-nucleus RNA-seq data and identified gamma-secretase and HP1 transcription pathways that a no-evidence frequentist setting did not recover. Key Findings 427 ROSMAP samples: The application used postmortem prefrontal cortex single-nucleus RNA-seq data from 427 Religious Orders Study and Memory and Aging Project samples. …

Mental-Health AI Agents Still Lack Real Clinical Validation

TL;DR: A 2026 medRxiv review found that mental-health AI agents are moving quickly toward large-language-model chatbots, but most systems still rely on text self-report, narrow depression/anxiety/suicide use cases, and offline tests rather than prospective clinician or patient trials. Key Findings More than 300 recent papers were reviewed: Researchers audited mental-health AI agent systems from 2023 …

VR-CBTp for Paranoia May Fit Higher Avolition and Delusion Severity

TL;DR: A 2026 study in Psychological Medicine found that people with schizophrenia spectrum disorders and higher avolition or moderate-to-high delusion severity appeared to improve more after virtual reality cognitive behavioral therapy for psychosis (VR-CBTp), while lower delusion severity favored standard CBTp. Key Findings FaceYourFears dataset: The exploratory moderator study used trial data from 254 participants, …

Fluorescent Aptamers Linked Brain Cell Identity to Connectomics

by
Fluorescent Aptamers Linked Brain Cell Identity to Connectomics

TL;DR: A 2026 Nature Communications paper introduced CAptVE, a fluorescent aptamer method that labels molecular features in mouse brain tissue while preserving ultrastructure for electron-microscopy connectomics. Key Findings Detergent-free labeling: CAptVE used slow off-rate modified aptamers to label brain cells without detergent permeabilization that can disrupt ultrastructure. Three fixation steps: The optimized pipeline balanced fluorescence …
