There Is No Safe Gamble with High LDL Cholesterol
The article challenges the claim from the documentary *The Cholesterol Code* that “lean‑mass hyper‑responders” (LMHRs) on low‑carbohydrate, high‑fat diets can sustain extremely high LDL‑C without added atherosclerotic risk. It explains that LDL‑C is a proxy for apoB particle number, the true driver of plaque formation, and reviews two LMHR studies that lack proper controls, adequate follow‑up, and mechanistic validation. The piece argues that the proposed “lipid‑energy model” does not reconcile low triglycerides with elevated LDL‑C and that the causal link between apoB particles and cardiovascular disease remains robust across metabolic contexts.
Carefully Guided FGF8 Expression via Gene Therapy Enhances Digit Tip Regrowth in Mice
Researchers used a zebrafish-derived tissue‑regeneration enhancer to deliver fibroblast growth factor 8 (FGF8) via adeno‑associated virus, achieving focused up‑regulation of the gene in mouse digit tips. The therapy partially rescued regeneration in mice lacking SP6/SP8 transcription factors and accelerated tip...
Dasatinib and Quercetin Outperform Navitoclax in a Mouse Model of Intervertebral Disc Degeneration
Researchers compared two senolytic strategies in a mouse model of intervertebral disc degeneration, finding that the dasatinib‑quercetin (DQ) cocktail outperformed navitoclax. In SM/J mice, DQ lowered degeneration grades, reduced senescence markers such as p19ARF, p21, and SASP, and preserved nucleus...
Your North Star
The article proposes a holistic "North Star" health framework that defines true health as the ability to meet physical and cognitive demands with abundant energy, mental clarity, low anxiety, high libido, and pain‑free movement. It argues that traditional proxy markers—weight,...
Is Chronic Kidney Disease Accelerated Kidney Aging?
Chronic kidney disease (CKD) shares many structural and functional changes with normal kidney aging, but the decline in estimated glomerular filtration rate (eGFR) occurs at a markedly accelerated pace. Recent open‑access research highlights cellular senescence as a core driver of...
The Field of Dermatology Is Undergoing a Transformation
Dermatology is shifting from purely cosmetic, marketing‑driven procedures to science‑based longevity treatments that target the underlying mechanisms of skin aging. New therapies that clear senescent cells, modulate epigenetic clocks, and employ partial cellular reprogramming are delivering measurable improvements in barrier...
In Whales, a Long Life Absent Cancer Results From Superior DNA Repair Mechanisms
Researchers have identified that bowhead whales, which can live over 200 years, exhibit an unusually robust DNA repair system that underpins their low cancer incidence. Unlike elephants, which rely on multiple TP53 copies, whales appear to use alternative genome‑maintenance pathways...
Metabolic Acidosis May Be an Important Contributing Cause of Age-Related Frailty
A new open‑access study highlights metabolic acidosis—specifically low serum bicarbonate—as a potentially overlooked driver of age‑related frailty. Epidemiologic data link bicarbonate levels below 25 mEq/L to slower gait, reduced muscle strength, and higher mortality, even in seniors with normal kidney function....
What Breathing Can Teach Us About Handling Pressure in Sports (And Why Breathwork Is Key)
Elite athletes are turning breathwork into a performance advantage, with Rory McIlroy publicly crediting nasal breathing for staying calm during The Masters. The Oxygen Advantage® method teaches controlled, CO₂‑tolerant breathing that boosts oxygen delivery, vagal tone, and stress resilience. Major...
The Forgotten Guardian: Is This "Childhood" Organ the Key to Longevity?
A new study in *Nature* used AI to examine 25,000 heart and lung scans and found that adults with a healthier‑appearing thymus enjoy significantly longer lives, with up to a 50% reduction in overall mortality and a 63% lower risk...
Connecting Gompertz Law Parameters with Specific Outcomes in the Treatment of Aging
Researchers used large‑scale Caenorhabditis elegans experiments to re‑interpret the two parameters of the Gompertz mortality equation. They found that reductions in the β parameter correspond to an expanded period of late‑life frailty, while declines in α reflect genuine health‑span extension...
Benzodiazepine Withdrawal Is Mitochondrial Dysfunction
Benzodiazepines, widely prescribed for anxiety and insomnia, act as whole‑body drugs that target mitochondrial receptors, not just brain GABA pathways. Both chronic use and abrupt cessation can trigger mitochondrial dysfunction, linking the drugs to a roughly 60% increase in mortality...
How to Use Breathing to Control Your Emotions (The Neuroscience of Interoception)
The post explains how breathing and other bodily signals shape emotional experience through interoception. It cites classic experiments—such as the bridge study—and pharmacological evidence showing that heart‑rate changes alter perception of fear and attraction. Practical advice emphasizes using deliberate breath...
I Wear a Continuous Glucose Monitor. Here's What MOTS-C Did to My Numbers.
The author, a biohacker who monitors glucose continuously, reports that weekly injections of the mitochondrial peptide MOTS‑c consistently drop post‑meal blood sugar by about 20 mg/dL compared with baseline. The effect appears reproducible across multiple CGM recordings while keeping food intake...
The Gut Microbe in INDY Related Longevity in Flies
Researchers investigated how the longevity‑associated Indy gene influences the gut microbiome in Drosophila. Indy heterozygous flies displayed lower bacterial load and greater microbial diversity as they aged, while still achieving lifespan extension even in germ‑free conditions. The study linked Indy...
