  "summary": "This preliminary animal study used an automated image-processing and machine-learning pipeline to assess whether RF-EMR exposure is associated with differences in Drosophila brain morphology. The authors report that classifiers could discriminate between microscopic brain images from exposed versus non-exposed flies, with improved performance after genetic algorithm-based feature selection. Exposure details and sample size are not provided in the abstract, limiting interpretation of biological significance.",

    "A neural network reportedly achieved the best classification accuracy with the selected feature subset.",
    "A statistical test reportedly supported that feature selection significantly improved classifier performance.",
    "The abstract does not report RF-EMR exposure parameters (frequency, SAR) or the number of specimens/images."
