The US FDA and EMA collaborate on a risk-based AI governance framework to harmonize oversight of AI-driven drug discovery, clinical trials, and manufacturing, ensuring safety, efficacy, and ethical deployment of emerging technologies.

Key points

• FDA’s AI Steering Committee aligns over 20 AI use cases across agency offices under a unified risk-based evaluation.
• EMA’s 2023–2028 AI work plan focuses on guidance, policy, tool development, and personnel training for medicines regulation.
• Recommendations include legislative updates, global harmonization via ICH, capacity building, and leveraging digital twins and SaMD oversight.

Why it matters: A unified AI governance framework streamlines drug development, mitigates regulatory fragmentation, and maintains high safety standards for AI-driven therapeutics.

Researchers at Northwestern University develop an automated image processing pipeline employing computer vision and unsupervised learning to segment and generate acquisition coordinates for nanoscale particles. By adaptively sizing boxes based on pixel intensity clusters, the approach reduces redundant sampling and accelerates STEM-based analysis workflows, achieving a 25–29× acceleration compared to uniform grid methods.

Key points

• Image preprocessing downsizes to 128×128px and uses sharpening, Gaussian blur, and adaptive thresholding to isolate nanoparticle regions.
• 1D k-means clusters pixel intensities using composition-informed k estimation to segment grayscale images into meaningful regions.
• Custom box-generation algorithm produces up to 260× fewer acquisition points, achieving a 25–29× speedup in STEM workflows.

Why it matters: This pipeline dramatically streamlines nanoparticle analysis, enabling scalable, focused STEM data collection and accelerating materials discovery pipelines.

Researchers from Karabuk University and Antalya Oral and Dental Health Hospital assess ChatGPT 3.5 and Google Gemini performance in addressing parent queries on pediatric dental trauma. They employ the DISCERN instrument and PEMAT-P tool to evaluate response quality, understandability, and actionability. Both chatbots deliver comparable guidance, with Gemini showing marginally higher reliability and ChatGPT demonstrating superior clarity, yet neither system substitutes professional dental consultation.

Key points

• ChatGPT 3.5 and Google Gemini are evaluated using the DISCERN instrument, with Gemini achieving marginally higher mean reliability scores.
• PEMAT-P analysis shows ChatGPT delivers superior understandability and both chatbots provide similar actionability for pediatric dental trauma guidance.
• Study uses 17 IADT-based case scenarios with inter-rater Cohen’s kappa of 0.72–0.78 and parametric statistical tests to compare chatbot performance.

Why it matters: This study validates AI chatbots as accessible, consistent sources of pediatric dental trauma guidance, heralding scalable support alongside clinical expertise.
