Longevity Watch
Advances in global aging research: clinical studies, measurement technologies, biotech.
Sleep Regularity: A Stronger Predictor of Mortality Than Sleep Duration
A cohort of 60,977 adults followed for 7.8 years shows that when you go to bed matters more than how many hours you sleep. Analysis of circadian mechanisms and the blood biomarkers affected.
Biological Age: Five Approaches to Measuring How You Really Age
Chronological age says nothing about your actual condition. Epigenetic clocks, blood biomarkers, proteomics: science now offers concrete tools to quantify aging.
The Centenarian Microbiome: What Science Says and What the Industry Sells
Akkermansia, Bifidobacterium longum, Bacillus subtilis: the bacteria associated with centenarians are heavily marketed. Why we chose not to include them in the Singular formula.
Sun Exposure and Longevity: The Paradox Dermatology Refuses to See
Large epidemiological cohorts converge: total sun avoidance is a mortality risk factor comparable to smoking. Mechanisms, data, and the optimal exposure window.
Psychedelics and Neuroplasticity: When Science Separates the Trip from the Therapeutic Effect
Psilocybin, ketamine, LSD, DMT: psychedelics restart synaptogenesis through now-identified mechanisms. Non-hallucinogenic analogues open an unprecedented path for brain aging.
Antibiotics and the Microbiome: An Eight-Year Scar
A Nature Medicine study of nearly 15,000 adults reveals that certain antibiotics reduce gut diversity for up to eight years. A data-driven analysis of the findings and their implications.
Longevity diets: what epidemiological data actually shows
Blue Zones, Mediterranean diet, Okinawa: a critical analysis of the methodological biases in population studies on diet and longevity. What remains when survivor bias is removed?
ER-100: The First Partial Epigenetic Reprogramming Therapy to Reach a Human Clinical Trial
Life Biosciences received FDA clearance to test ER-100, an OSK gene therapy for cellular rejuvenation, in patients with optic neuropathies. A comprehensive analysis.
Gene therapy and longevity: from follistatin to genome editing
From AAV vectors to CRISPR, gene therapy now targets aging itself. Follistatin, telomerase, klotho, APOE: a rigorous scientific assessment of where we stand.
Mesenchymal Stem Cells: Promises and Realities of Regenerative Medicine
MSCs fascinate with their differentiation capacity and paracrine activity. From clinical trials to commercial clinics and cell-free therapies, a rigorous assessment.
Longevity Pharmacology: The Molecules Under Scientific Surveillance
A critical overview of pharmaceutical molecules studied for their potential impact on human longevity. Animal data, clinical trials, mechanisms, and limitations.
The mTOR Pathway: The Precarious Balance Between Cell Growth and Longevity
mTOR is the central kinase regulating growth, protein synthesis, and autophagy. Longevity science reveals a fundamental paradox: what drives growth in youth accelerates aging. A scientific breakdown.
Bioactive Peptides: Between Laboratory Promises and Clinical Reality
BPC-157, TB-500, GHK-Cu, Epithalon, MOTS-c: a scientific review of the peptides championed by the longevity community. Evidence levels, animal vs human data, real risks.
Heterochronic Parabiosis: Can Young Blood Reverse Aging
From parabiosis experiments to young plasma clinics, science explores blood-borne aging factors. A rigorous assessment of promises, controversies, and evidence.
Blood Donation: An Unexpected Lever for Longevity
Regular iron depletion through blood donation reduces oxidative stress, improves insulin sensitivity, and stimulates haematopoietic renewal. Epidemiological data and mechanisms.
Cellular Senescence: When Your Cells Refuse to Die
Senescent cells accumulate with age and secrete an inflammatory cocktail (SASP) that accelerates tissue aging. Mechanisms, biomarkers, and senolytic leads under investigation.
Epigenetic Clock: Your Biological Age Is Not Your Chronological Age
DNA methylation enables biological age measurement with 2 to 3 years precision. The Horvath and GrimAge clocks open the path to longitudinal monitoring of aging trajectories.
Medicine 3.0: The Transition from Clinical Intervention to Proactive Optimization
Waiting for biomarkers to turn red before intervening is a strategy built for emergencies, not chronic prevention. A different medical logic is emerging.
