A study by American researchers in the Journal of Endocrinology Society demonstrates that daily vitamin D supplementation significantly reduces telomere attrition over four years, equating to about three years less biological aging. The study measured telomere length in 1,054 participants and found that consistent vitamin D intake preserves chromosomal integrity, suggesting implications for age-related disease prevention and healthy lifespan extension.

Key points

• Longitudinal Telomere Assay: four-year qPCR measurement of telomere length in 1,054 participants quantifies attrition rates.
• Vitamin D Intervention: daily cholecalciferol supplementation correlates with ~3 years less biological aging by reducing telomere shortening.
• Genomic Stability: findings demonstrate vitamin D’s role in maintaining telomeric integrity to support healthy lifespan extension.

Why it matters: This study highlights vitamin D's therapeutic potential in preserving chromosomal integrity and offers a novel approach to age-related disease prevention and longevity.

Researchers at leading biotech firms apply CRISPR-Cas9, base editing, and prime editing to modify genes tied to cellular aging, such as SIRT1 and FOXO3. They leverage both ex vivo stem cell approaches and lipid nanoparticle delivery in vivo to develop potential one-time therapies against cardiovascular and neurodegenerative conditions.

Key points

• Ex vivo CRISPR-Cas9 editing of HSCs targets longevity genes (SIRT1, FOXO3) with HDR precision.
• Base and prime editing platforms reduce off-target effects compared to standard Cas9, enhancing specificity.
• Lipid nanoparticle delivery achieves >80% in vivo gene disruption of PCSK9 and ANGPTL3 in mouse liver.

Why it matters: This breakthrough signifies a paradigm shift in anti-aging therapeutics, enabling precise genetic interventions to enhance healthspan over traditional drug approaches.

Time.news' feature interview with Dr. Vivian Holloway presents evidence-based interventions—ranging from early-life habit formation and regular strength training to nighttime fasting and cognitive challenges—that collectively contribute to enhanced healthspan and functional resilience. By emphasizing a multi-dimensional approach to inflammation control, metabolic health, and muscle preservation, this holistic framework underscores practical, scientifically grounded strategies for mitigating age-related decline.

Key points

• Time-restricted feeding protocols activate autophagy pathways and improve insulin sensitivity via extended nightly fasting windows.
• Resistance training preserves muscle fiber integrity and counteracts sarcopenia by stimulating mTOR-mediated protein synthesis.
• Neurocognitive stimulation supports synaptic plasticity and memory retention, mitigating age-related decline in executive functions.

Why it matters: This integrated lifestyle framework offers accessible, evidence-backed methods to prevent age-related decline, potentially reshaping public health and geroprotection.

Researchers at University Medical Center Ho Chi Minh City employ a pretrained MobileNetV2 neural network to classify 3,164 microscopic vaginal discharge images into bacterial, fungal, or mixed-infection categories. They preprocess and augment images, then train and validate the model to achieve F1 scores above 0.75 and AUC-PR above 0.80, improving diagnostic consistency.

Key points

• MobileNetV2 model classifies 3,164 wet-mount vaginal discharge images into bacterial (Group B), Gardnerella vaginalis (Group C), or fungal (Group F) infection categories.
• Preprocessing pipeline includes 800×800px resizing, sharpening, rotations, and contrast adjustments to standardize and augment input data.
• Model achieves F1 scores >0.75 and AUC-PR >0.80 across datasets, exceeding 0.90 performance for Gardnerella vaginalis detection, with 86.9% expert agreement.

Why it matters: By enabling rapid, standardized vaginitis screening with a mobile-friendly AI model, this approach can reduce diagnostic errors and expand access in resource-limited settings.
