🫀 Thymus as Longevity Organ: AI analysis of CT scans across 25,000 adults finds that healthy thymus tissue predicts a 50% lower risk of all-cause death and 63% lower cardiovascular death risk, reframing this overlooked organ as a modifiable longevity target. 🧠 Cognitive Disability Rising Fast in Young Adults: Self-reported cognitive disability in US adults under 40 has nearly doubled since 2013, making younger adults the primary driver of overall cognitive impairment for the first time on record. 🖨️ Adhesive-Free Wearable Tracks Metabolism Continuously: A 3D-printed University of Arizona device, published in Nature Communications on May 10, monitors dehydration, metabolic shifts, and stress through skin gas emissions with no adhesive and no skin irritation. 💊 Eli Lilly Goes All-In on AI Drug Discovery: A $2.75 billion deal with Insilico Medicine signals that Big Pharma has moved from piloting AI to fully integrating AI-first companies as primary R&D partners. ⏱️ Fasting Windows Alone Do Not Boost Metabolism: A controlled study finds that intermittent fasting without calorie reduction produces no measurable metabolic or cardiovascular benefit, confirming that caloric balance, not timing alone, is the key driver.

⚖️ Weight and Brain Age — A 24-year study finds that sustained weight management may preserve brain age by up to two years, directly slowing the rate of memory and executive function decline. 💉 Gut Bacteria Inject Proteins Into Immune Cells — Scientists discover microbes use molecular injection systems to directly modulate immune cell behavior, explaining how microbiome composition drives systemic health outcomes. 🔓 OpenBind Opens AI Drug Discovery to Everyone — A UK consortium releases the first public AI model for atomic-level protein-drug binding prediction, leveling the pharmaceutical research playing field. 📊 Wearables Predict Insulin Resistance at 80% Accuracy — The WEAR-ME study shows wearable data plus standard blood tests can identify insulin resistance years before diabetes develops, using devices most people already own. 🏋️ Grip Strength Cuts Mortality Risk by 33% in Older Women — A JAMA study of 5,000 older women finds that high grip strength independently predicts survival, even among those who do not meet aerobic exercise guidelines.
