A team at the Mechanobiology Institute, National University of Singapore, engineers hybrid polyacrylamide–ECM scaffolds that decellularize heart tissue in situ and tune stiffness independently to probe age-related biochemical and mechanical effects on cardiac fibroblasts.

Key points

• DECIPHER embeds thin murine heart slices in acrylamide pretreated with formaldehyde to form stable polyacrylamide–ECM hybrids while preserving native ligand distribution.
• Hydrogel formulations are tuned to Young’s moduli of ~10 kPa or ~40 kPa, replicating young and aged cardiac tissue stiffness independently of ECM composition.
• Young ECM ligand presentation overrides profibrotic stiffness in maintaining cardiac fibroblast quiescence; aged ECM drives activation and senescence through specific receptor and mechanotransduction pathways.

Why it matters: This platform decouples biochemical ligands and mechanics in aged cardiac ECM, offering precise targets for anti-fibrotic and rejuvenation therapies.

Atomwise’s AtomNet and the DeepDock initiative employ advanced convolutional and graph-based neural network architectures to predict ligand binding poses and bioactivity by extracting spatial atomic features from 3D protein–ligand complexes. Trained on extensive PDB and bioactivity datasets, these AI models refine virtual screening by reducing false positives and prioritizing high-affinity candidates, thereby accelerating lead identification.

Key points

• DeepDock employs deep neural networks trained on PDB ligand complexes to accurately predict protein–ligand docking poses, outperforming classical scoring functions.
• AtomNet uses 3D convolutional grids of protein and ligand atomic properties to directly predict bioactivity, enhancing hit enrichment in virtual screening campaigns.
• AI-driven binding site models leverage CNNs and graph neural networks to identify ligand-binding pockets from protein structures, enabling targeted screening of previously uncharacterized sites.

Why it matters: By significantly improving virtual screening accuracy and reducing false positive rates, AI-driven docking accelerates drug discovery and lowers development costs.

A research team from CSIRO’s Australian e-Health Research Centre, The University of Queensland, and international collaborators introduce CLIX-M, a clinician-informed 14-item evaluation checklist for explainable AI in clinical decision support systems. CLIX-M spans four categories—Purpose, Clinical, Decision, and Model attributes—offering expert-derived metrics, Likert-scale assessments, and guidance on reporting development and clinical evaluation phases.

Key points

• Introduces CLIX-M, a 14-item checklist covering Purpose, Clinical, Decision, and Model attributes for XAI evaluation.
• Incorporates expert-informed metrics such as domain relevance, coherence, actionability, correctness, confidence, and consistency.
• Utilizes quantitative methods like bootstrapping confidence intervals, feature agreement analysis, and bias assessment tools.

Why it matters: Standardized XAI evaluation enhances transparency and trust, accelerating safe integration of AI-driven decision support into clinical practice.

A team led by Duke-NUS Medical School conducted a comprehensive scoping review of 467 clinical AI fairness studies. They catalogued medical fields, bias-relevant attributes, and fairness metrics, exposing narrow focus areas and methodological gaps, and offered actionable strategies to advance equitable AI integration across healthcare contexts.

Key points

• Reviewed 467 clinical AI fairness studies, mapping applications across 28 medical fields and seven data types.
• Identified that group fairness metrics (e.g., equalized odds) dominate over individual and distribution fairness approaches.
• Found limited clinician-in-the-loop involvement and proposed integration strategies to bridge technical solutions with clinical contexts.

Why it matters: Addressing identified fairness gaps is crucial to ensure equitable AI-driven diagnoses and treatment decisions across all patient populations.

Scientists at the AgeTech Institute identified bloodborne bacterial compounds that exhibit potent antioxidant and anti-inflammatory properties, slowing cellular senescence through telomere maintenance and enhanced DNA repair.

Key points

• Isolation of bacterial molecules from the blood microbiome demonstrating antioxidant and anti-inflammatory activity.
• Evidence that these compounds modulate cellular aging pathways, including telomere maintenance and DNA repair.
• Evaluation of delivery methods spanning topical serums, oral supplements, and intravenous infusions in preclinical models.

Why it matters: This discovery reveals the blood microbiome’s untapped potential for developing targeted anti-aging therapies, offering more natural and effective longevity interventions.
