This week: AI beat doctors at diagnosis. Genes decide more of your lifespan than we thought. And rapamycin might be quietly cancelling Silicon Valley's workouts.

🔬 The Big Story
AI just beat internal medicine doctors at diagnosing real patients. The catch nobody's talking about.
Harvard and Beth Israel researchers handed an OpenAI reasoning model the actual records of real ER patients — incomplete, contradictory, real. Then they had two experienced internal medicine doctors do the same.

The AI won.
One case: a patient with a pulmonary embolism kept getting worse. The team blamed the meds. The AI scanned the chart, flagged a possible lupus history, and pointed to heart inflammation. It was right.
But here's what nobody's saying:
The study compared AI to two physicians. Two. On retrospective records, not live patients.
What happens when the doctor disagrees with the AI in real time?
What happens when AI is confidently wrong?
We're about to find out.

🔸An open-source AI just made drug design free for anyone with a laptop
University of Virginia researchers released YuelDesign - a suite of AI tools that designs drug molecules atom-by-atom, accounting for how proteins flex during binding. The kicker: completely free. Three papers, three top journals, zero licensing.
What happens when a lab in Lagos can chase the same diseases as Pfizer?
🔸Your Oura Ring may know your heart age better than your doctor
A PLOS Digital Health study found overnight pulse signals from a consumer ring estimate vascular age as accurately as clinical sensors. Estimates correlated tightly with blood pressure.
The $300 ring on your finger may flag heart trouble before your annual physical does. Whether your cardiologist wants to hear that is a different question.
🔸The "longevity drug" Silicon Valley loves might be cancelling out their workouts
Rapamycin, the off-label longevity favorite may blunt the health benefits of exercise, per an April 29 study. Researchers expected the opposite.
Thousands of biohackers are taking a drug that might be undoing the very thing they're optimizing for. Nobody's told them yet.

🌍 Beyond AI
The 20% lifespan rule was wrong. The new number changes everything
For decades, the textbook line was that genetics accounts for ~20% of human longevity. A Science paper published April 30 just doubled it — lifespan is 50% heritable, on par with height.

The old number came from people born between 1870 and 1900, who lived through wars and pandemics that scrambled the genetic signal. Modern data, modern math, completely different answer.
Half the longevity industry just had its central premise rewritten. The other half hasn't read the paper yet.

🐰 Rabbit Hole
Three links worth falling into this week:
Image source: ChatGPT/AIHealthTech Insider
The UnitedHealth AI lawsuit is about to crack open. A federal judge gave the insurer until April 29 to hand over internal docs on nH Predict — the AI families say wrongfully denied care to elderly patients. 90% of denials get reversed on appeal. Only 0.2% of patients ever appeal. What's in those documents? → Read it
Patients are now using AI to fight insurance AI. Bloomberg profiled Claimable, which drafts appeals against AI-generated denials. It's already reversed thousands. The founder calls it "an arms race the patient was always supposed to lose." → Read it
The WHO just mapped AI adoption across all 27 EU countries. Three-quarters use AI in clinical diagnostics. The US has no comparable map of itself. → Read it

💡 The One Thing
AI out-diagnosing doctors. Drug discovery going open-source. Half your lifespan locked in your DNA.
A lot landed this week. But one question keeps surfacing and we want your take.

Would you let an AI diagnose you in the ER if it had a better track record than the doctor on shift?
