17α-Estradiol Preferentially Protects APOE4 Male Mice Against Aging

Main Finding The longevity drug 17α-estradiol (17αE2) provides greater protection against aging-related decline in male mice carrying the APOE4 gene variant compared to APOE3 mice. APOE4 is associated with shorter lifespan and higher Alzheimer’s disease risk, but 17αE2 treatment largely reverses these negative effects. Key Results Aging Markers Metabolic Improvements Brain Function Molecular Changes Study […]

Fasting and Calorie Restriction Effects on Lifespan: Insights from a 960-Mouse Study with Human Biomarker Validation

TL;DR: A large-scale mouse study (n=960) found that both fasting and calorie restriction (CR) extended lifespan, with 40% CR showing the most dramatic results (36% increase in median lifespan). The 40% CR group also maintained youthful physical activity levels throughout life. Key biomarkers like lymphocyte count and red blood cell distribution width (RDW) strongly predicted

The 2024 Longevity Breakthrough: From Mouse Models to Human Potential – A Comprehensive Review of Bill Falloon’s RAADfest Presentation

TL;DR Bill Falloon presents compelling recent advances in age reversal research, particularly focusing on young plasma therapies and OS (Yamanaka) transcription factors. Key 2024 breakthroughs include exosome-rich young plasma cutting epigenetic age in half in rats and OS factors doubling remaining lifespan in aged mice. These interventions are now moving to primate studies, with potential
