An interpretable logistic regression model trained on YRBS data predicted lifetime marijuana use among male high school students with high accuracy, enabling early identification of at-risk boys for targeted school and community prevention.

A cross-sectional study of 8285 male high school students from the 2023 Youth Risk Behavior Surveillance System used 36 demographic, behavioral, and psychosocial predictors to model lifetime marijuana use, reported by 28.4% of participants. After benchmarking 17 algorithms, an optimized logistic regression model with SHAP and LIME explanations achieved AUC 0.9034 and accuracy 0.8582.

AI tools integrated into radiation therapy workflows can improve efficiency by automating organ-at-risk contouring tasks.

This peer-reviewed educational perspective from August 2026 examined how organ-at-risk contouring is taught in an Australian undergraduate radiation therapy program as AI auto-contouring enters clinical workflows. The authors reviewed curriculum scope and technologies and examined students' preferred methods, confidence across OARs, and perceived factors affecting quality.

In 2230 MIMIC-IV adults with AKI, higher TyG-FI was independently associated with ICU and 28-day mortality and enabled identification of lower-burden versus high frailty-organ dysfunction phenotypes that reproduced in 1831 eICU patients with high agreement.

Researchers derived and tested the triglyceride-glucose frailty index in 2230 MIMIC-IV adults with KDIGO-defined AKI, examining associations with ICU, in-hospital, 28-day, 90-day and 365-day mortality, identifying two consensus phenotypes, and evaluating 12 prediction algorithms with SHAP and LIME interpretation and external validation in 1831 eICU patients.

Sentinel-2-based AGB estimation using CART with the Sun et al. (1980) diameter-based allometric reference achieved the closest agreement with forest management plan data at the management-unit scale in Pinus brutia stands.

On 2026-08-22, a peer-reviewed study reported testing how three different allometric reference datasets affect Sentinel-2-based aboveground biomass mapping in Pinus brutia. Using 112 field plots and CART as primary model with Random Forest as robustness check, authors mapped biomass over 13,687 ha and compared totals to forest management plan data.

In academia, the same ChatGPT use for personal skill development may impair a person's capacity for critical thought and content production and provide false information tied to training dataset errors.

As of March 27 2024, this peer-reviewed review examined ChatGPT, described as Chat Generative Pre-trained Transformer, often referred to as ChatGPT-4, and its uses in academia. Using a noticing-collecting-thinking approach to review literature and online resources, it categorized opportunities and constraints into research, education, personal skill development, and social aspects.

LLM chatbots supporting GBV survivors can generate hallucinations or errors that create unintended harms for individual users.

Published 7 November 2025 in International Review of the Red Cross, this peer-reviewed analysis examined proposals to use LLM-powered chatbots to provide direct care, information and mental health and psychosocial support to women and girls in armed conflicts and humanitarian emergencies, with a focus on gender-based violence survivors.

Emotional AI risks hollowing human connection by replacing shared vulnerability with predictive performance, fostering emotional substitution and blurring authentic care with algorithmic response.

Published November 17 2025 in Frontiers in Psychology, the article examines how AI has moved into emotion through affective computing that detects and simulates affect. It describes chatbots like Replika, Woebot and Kuki and therapeutic bots that use warmth and validation cues, and argues they create a compassion illusion where recognition is mistaken for resonance.

The same RAG constraints that ensured accuracy limited broader inquiries, creating tension between reliability and comprehensiveness that shaped study routines.

In a medical school basic science course, researchers deployed a retrieval-augmented teaching assistant that limited large language model outputs to instructor-curated materials across two consecutive cohorts. They tracked when and how students used it and what they asked, finding strategic, context-dependent adoption with heavier use during high-stakes assessments and after hours.
