Researchers at the University of Kentucky and collaborators design MyoVision-US, a software leveraging DeepLabV3 with a ResNet50 backbone for semantic segmentation and post-processing to quantify quadriceps and tibialis anterior thickness, cross-sectional area, and echo intensity. The AI achieves excellent consistency (ICC >0.92) and reduces analysis time by 99.8%, aiding critical and chronic illness assessment.

Key points

• DeepLabV3-ResNet50 models segment quadriceps complex and tibialis anterior ultrasound images.
• Post-processing uses contour extraction, morphological opening/closing, and cubic spline smoothing to refine masks.
• Software calculates muscle thickness, cross-sectional area, and echo intensity via pixel counts and grayscale averaging.
• Validation shows Dice ~0.90, IoU ~0.88, and ICCs of 0.92–0.99 compared to manual analysis.
• Automated pipeline analyzes 180 images in 247 s versus 24 h manually, saving 99.8% of analysis time.

Why it matters: Automating muscle ultrasound analysis transforms bedside assessments by delivering rapid, reproducible measurements that previously required expert manual effort. This scalability can improve monitoring of muscle wasting in critically ill and cancer patients, reduce human bias, and pave the way for real-time clinical integration.

An aging research team applies miRNA enrichment analysis and an age-related genetic database to isolate a four-strand microRNA cocktail (E5) within stem-cell–derived extracellular vesicles. Delivered to senescent fibroblasts, E5 downregulates p16, p21 and inflammatory interleukins, outperforming native vesicles. In naturally aged mice, systemic E5 injections reduce senescence and DNA damage markers in liver tissue, highlighting a non-senolytic approach to cellular rejuvenation.

Key points

• Four-miRNA cocktail (E5) derived from stem cell EVs modulates senescence.
• Delivery via extracellular vesicles reduces SA-β-gal activity by ~30% in fibroblasts.
• E5 downregulates p21, p16, IL-1β and IL-6 through PCAF and HIPK2 suppression.
• In 24-month-old mice, systemic E5 dosing lowers senescence and DNA damage markers in liver tissue.
• Non-senomorphic approach spares cell viability while targeting aging pathways.

Why it matters: This miRNA-loaded EV approach offers a non-senolytic alternative that reprograms aging cells without inducing cell death, potentially reducing side effects of current therapies. By targeting multiple senescence pathways, it could pave the way for precise, rejuvenative treatments in age-related diseases.

A team led by Rabinowitz published in IJ STEM Ed demonstrates how embedding foundational machine learning modules within informal learning settings—such as after-school programs and science clubs—enables high school students to conduct ecological modeling and genetic data analysis, thereby enhancing computational thinking.

Key points

• Accessible programming modules introduce supervised and unsupervised machine learning tasks.
• Informal settings like after-school clubs provide flexible, collaborative environments for data-driven science.
• Curriculum addresses feature selection, overfitting, and evaluation metrics to build robust modeling skills.
• Structured mentorship supports autonomy and growth mindset while preventing cognitive overload.
• Mixed-method assessments show significant gains in students’ computational thinking, data literacy, and STEM interest.

Why it matters: Embedding machine learning into informal science education shifts the paradigm by democratizing access to computational skills and lowering classroom barriers. This scalable model fosters data literacy across diverse youth populations and equips the next generation with tools vital for addressing complex societal and scientific challenges.

A team from Nanjing Audit University investigates how Big Five personality traits influence static and dynamic trust in AI-driven drone missions across PC and VR modalities. Using a D3QN-based UAV simulation in Unity, they measure trust before and after interaction to inform adaptive, personality-aware human–machine interface designs.

Key points

• Unity-based UAV surveillance simulation uses D3QN for autonomous path planning and obstacle avoidance.
• Chinese TIPI questionnaire measures Big Five traits; extroversion and emotional stability highlighted.
• Static trust (T0) assessed pre-interaction; dynamic trust (T1) measured post-interaction on PC and VR.
• Extroversion significantly predicts initial trust; emotional stability enhances post-interaction trust in PC.
• Static trust consistently predicts dynamic trust across modalities, explaining up to 21.9% of T1 variance.
• VR yields higher initial trust, while PC delivers greater dynamic trust, per independent t-tests.

Why it matters: By revealing static trust as the foundation for evolving human-machine trust and identifying extroversion and emotional stability as key drivers, this study guides the design of adaptive, user-centric AI systems. Tailoring interfaces to individual personalities can enhance safety, reliability, and long-term engagement in AI applications.

Researchers at UT Health San Antonio define immune resilience as the capacity to balance inflammation and immune defense, stratifying over 17,000 participants into preservers, reconstituters, or degraders based on T-cell markers and TCF7 expression. Their analysis reveals a significant survival advantage linked to robust immune profiles.

Key points

• Classified ~17,500 individuals into IR-preservers, reconstituters, and degraders using CD4/CD8 ratios
