Our new longevity movie just premiered on Apple TV. It's called Forever Young. I had the privilege of joining a remarkable group of scientists, physicians, and patients to explore one of the most profound questions in medicine: can we slow, stop, or even reverse aging? (1/4)
The lie I taught in medical school: calories are calories, and when you eat them doesn't matter. New pilot data says otherwise. (1/7)
The lie I taught in medical school: exercise helps the brain mainly through better blood flow and mood. That framing is now looking incomplete. (1/6)
I've spent decades trying to understand why some patients age gracefully into their 90s and 100s while others accumulate disease in their 60s. A new study in GeroScience gives us a chemical fingerprint. (1/6)

New in Nature Communications (July 2026): scientists engineered an enzyme that reverses one of the most stubborn chemical hallmarks of aging in human tissue. (1/6)
28% Lower Dementia Risk From Two Foods You Probably Already Have That's the finding from a UK Biobank analysis of 121,986 adults. The highest consumers of flavonoid-rich foods — particularly tea and berries — had a 28% lower risk of dementia than the lowest consumers. (1/7)
