New in The Lancet (published July 12, 2026): the LatAm-FINGERS randomized controlled trial in 1,065 older adults across 11 Latin American countries. (1/7) Two years. Two groups. Same population. One structured lifestyle program (supervised exercise 4x/week, MIND diet coaching, computerized cognitive training, cardiovascular risk monitoring, 38 group meetings) vs. general lifestyle advice (4 total meetings). (2/7)

The conventional wisdom that only medication moves blood pressure meaningfully is wrong. (1/8) A meta-analysis in the Journal of Hypertension pooled five randomized controlled trials (390 adults) of Hibiscus sabdariffa — sour tea — versus control. Result: systolic BP fell 7.58 mmHg and diastolic BP fell 3.53 mmHg. (2/8)

New in Nutrition Reviews (Prokopidis, 2024): a meta-analysis of 10 placebo-controlled RCTs found daily creatine monohydrate modestly improved memory in healthy adults — with the biggest effects in older adults, vegetarians, and the sleep-deprived. (1/6) Effects were small-to-moderate (SMD ~0.29 for memory) but consistent at 3-5 g/day for 2-24 weeks. Creatine regenerates ATP inside neurons, giving brain cells more available energy under cognitive or metabolic stress. (2/6)

Your bones and muscles talk to each other every second of every day. New research just mapped exactly how. (1/8) In a study in Bone Research, scientists used spatial transcriptomics to build the first cellular-resolution map of communication between bone and skeletal muscle. (2/8)

New in the New England Journal of Medicine: a randomized crossover study found that one or more cups of coffee daily cut sleep by an average of 36 minutes over 2 weeks compared to abstaining. (1/8) A 2023 meta-analysis of 24 caffeine-sleep RCTs put a hard number on the timing rule: to protect sleep, finish your last cup at least 9 hours before bed. (2/8)

Ultra-processed food doesn't just show up on the scale. It shows up in your blood. (1/8) A new study published this week identified a distinct metabolic "signature" in the blood of people eating more ultra-processed food -- a pattern of metabolites and lipids associated with worse cardiometabolic risk. (2/8)

Belly fat isn't just about calories — after 50, your body builds it differently. (1/7) New in Science: City of Hope + UCLA researchers used single-cell RNA sequencing on fat tissue from mice and humans across ages. (2/7)

New in JAMA Network Open: a 12-month RCT (INVEST in Bone Health, n=150 older adults with obesity) tested weighted vests vs resistance training during dietary weight loss. (1/7) The result: neither strategy fully offset weight-loss-related hip bone loss. So a vest is not a magic bullet during aggressive dieting. (2/7)

Toast and coffee is not a breakfast. It is a 16-hour muscle-building blackout. (1/7) The typical Western breakfast delivers 5-15g protein -- below the leucine threshold that triggers muscle protein synthesis. (2/7)

A 91-year-old physicist may have just rewritten the theory of aging. (1/8) Dr. John G. Cramer, Emeritus Professor of Physics at U Washington, spent 60 years smashing gold nuclei at Brookhaven and CERN. At 91, he turned his physicist's mind on his own body — and wrote "How to Live Much Longer: The Mitochondrial DNA Connection" (Springer 2026). (2/8)

Your blood sugar can look perfectly normal for ten years while your body is quietly breaking. Because the number that actually moves first isn't glucose — it's the hormone your physical almost never measures: fasting insulin. (1/9) Here's the trap. At your annual physical they check fasting glucose and maybe A1c. Both can sit in the "normal" range while insulin resistance has been building for years. (2/9)

A 10-year follow-up of the CENTRAL and DIRECT-PLUS lifestyle trials (n=366) in Circulation: despite participants regaining the weight, every 10% reduction in visceral fat during the original intervention was independently associated with a 28% lower long-term risk of type (1/7) 2 diabetes. (2/7)

I'm a medical school professor. I taught this stuff for decades. And I still ended up with four chronic diseases at once.

I did everything I was told. I followed the food pyramid. I exercised. I got my annual checkups. (1/8) Then I was diagnosed with four diseases at the same time — type 2 diabetes, high blood pressure, gout, and abnormal cholesterol. The full picture of metabolic syndrome. These were diseases my own father didn't get until his 80s, and I was decades younger. (2/8)

Ask a longevity doctor: does walking after meals actually work? Yes — and here's the mechanism. (1/5) When you eat, your blood sugar rises. If you sit on the couch, it stays elevated longer. If you walk — even gently, even for 10 minutes — your muscles pull that glucose out of your blood and use it for fuel. (2/5)

The most counterintuitive sleep tactic in the literature: a HOT shower 60-90 min before bed drops your CORE temperature faster than melatonin, magnesium, or blue-light glasses. (1/7) Mechanism: hot water dilates peripheral blood vessels. You step out, radiate heat outward, and core temp drops 2-3F. That core-temp drop is the actual hypothalamic trigger for slow-wave sleep onset. (2/7)

The story of longevity science has always been: find the world's oldest people, study what they do, copy it. A new book in Nature this week argues the foundation underneath that story is rotting. (1/6) In "Morbid: Debunking Modern Longevity Science" (MIT Press 2026), epidemiologist Saul Justin Newman shows up to 72% of supposed Greek centenarians turned out to be pension fraud -- people drawing benefits in the names of dead relatives. (2/6)

What if extreme longevity is less about avoiding aging and more about aging cleanly? (1/6) Maria Branyas Morera lived to 117 -- the oldest verified person on Earth. A new multi-omics study in Cell Reports Medicine (Santos-Pujol, Esteller et al) profiled her genome, epigenome, proteome, metabolome, and microbiome.

What they found: (2/6)
