Original analysis and signals
The research, explainers and short-form signals behind Singularity Wellness — written to be understood, not just summarized.
How Much You Sleep May Be Rewriting Your Biological Age — Just Not the Way Headlines Suggest
A landmark UK Biobank analysis found the least biological aging among people sleeping 6.4 to 7.8 hours nightly. Here's what it actually shows, and what it doesn't.
ArticleWhat Actually Counts as Recovery, and What's Just Rest
Recovery is a physiological process your body is doing, not a purchase or a feeling of being relaxed.
ArticleDo GLP-1 Drugs Slow Aging? What the New Industry Data Does and Doesn't Show
Novo Nordisk and Eli Lilly say their weight-loss drugs lowered 'aging clock' scores by two to four years. The data is real, early, and company-reported — and can't yet separate the drug from the weight loss.
ArticleMore REM Sleep, Lower Risk of 83 Diseases — in One Very Large, Very Observational Study
A 95,559-person UK Biobank analysis tied more REM sleep to lower risk of dozens of conditions, from heart failure to dementia. It's a strong signal, but it shows association, not cause.
ArticleAn FDA Panel Backed a Blood Test for 50+ Cancers. Here's What That Vote Actually Means
An advisory committee narrowly endorsed GRAIL's Galleri multi-cancer blood test. The underlying study measured how well it detects cancer — not whether finding cancer this way saves lives.
ArticleLate-Night Eating Is Linked to Higher Liver-Disease Risk — the 'When,' Not Just the 'What'
An analysis of nearly 200,000 people tied eating after dinner or bedtime to a 20-30% higher risk of fatty liver disease and cirrhosis. It's a meaningful association — and only an association.
ArticleApple Is Reportedly Building a Screen-Free Whoop Rival. Read It as a Signal, Not a Product
A Bloomberg report says Apple is prototyping a screenless fitness band. Nothing is confirmed — but the direction it points, toward screen-free continuous tracking, is already here.
SignalSleeping 6.4–7.8 Hours a Night Is Linked to the Lowest Biological Aging Across 23 Clocks
A 500,000-person UK Biobank analysis found a U-shaped relationship between nightly sleep duration and biological age across the brain, heart, lungs and metabolic system.
SignalA 350-Paper Review Argues Most Sedentary Adults Are Eating More Protein Than They Need
A University of Wisconsin-Madison review links lower protein intake to improved metabolism and reduced cellular damage, while affirming higher protein still benefits muscle growth in people who train.
SignalGarmin Launches CIRQA, a Screen-Free Smart Band With No Subscription
Garmin's first screenless wellness band tracks heart rate, SpO2, HRV, skin temperature and sleep for up to 10 days per charge, with no ongoing subscription fee.
SignalA 10-Marker Blood Panel Scores Biological Age Across 3,300 Adults in Europe
The MARK-AGE consortium built sex-specific biological-age formulas from routine blood biomarkers and found biologically younger scores tracked with healthier HDL, vitamin D and immune-cell profiles.
SignalA Blood Test Can Now Estimate the Biological Age of 11 Separate Organs
Stanford researchers linked organ-specific biological-age scores to future organ-specific disease risk and mortality, tracked over up to 17 years.
