🧫 Harvard Links Gut Bacteria to Depression via Inflammation: Morganella morganii produces a modified phospholipid that activates IL-6-driven immune inflammation, establishing a direct molecular pathway from gut bacteria to depression and creating new immune-targeted treatment targets. 🏥 FDA Launches Real-Time Clinical Trial Pilot: AstraZeneca and Amgen are feeding live trial data directly into FDA review systems in a landmark program that could compress cancer drug approval timelines by months and reshape how all clinical trials are conducted. 🌙 Fragmented Circadian Rhythms Accelerate Brain Shrinkage: Johns Hopkins researchers found that weaker daily rest-activity patterns in adults over 50 are directly tied to faster loss of memory-critical brain volume, making circadian health a modifiable and measurable neurodegeneration target. 😴 Chronic Insomnia Raises Dementia Risk by 40%: A six-year study of more than 2,700 adults links persistent insomnia to significantly greater amyloid buildup and white matter damage, reinforcing sleep quality as a primary dementia prevention strategy. 💰 Eli Lilly Bets $2.75 Billion on AI Drug Discovery: The massive Insilico Medicine commitment signals that major pharmaceutical companies now treat AI-designed drug candidates as legitimate pipeline assets, accelerating capital flow into the AI biotech sector ahead of critical Phase II readouts.

🧬 SuperAgers Grow 2.5x More New Neurons Than Their Peers — Northwestern researchers found that exceptional cognitive aging in adults over 80 is driven by dramatically elevated neurogenesis, offering a new biological target for brain longevity therapies. 🦠 Hidden Gut Virus Linked to Colorectal Cancer Risk — A previously unknown bacteriophage inside common gut bacteria appears at significantly higher rates in colorectal cancer patients, pointing to a new microbiome-based cancer screening opportunity. 💊 Novo Nordisk and OpenAI Join Forces for Drug Discovery — The partnership deploys AI across R&D, manufacturing, and commercial operations as pharmaceutical giants accelerate the race to AI-native drug pipelines. 🍽️ Fasting's Lifespan Benefit Lives in the Refeeding, Not the Fast Itself — UT Southwestern researchers traced the 60%-plus lifespan extension of fasting to the metabolic reset during refeeding, reframing how intermittent fasting protocols should be designed and studied. ⚡ Muscle Power Outperforms Strength as a Mortality Predictor — Mayo Clinic researchers found that the ability to generate force quickly is a stronger predictor of all-cause mortality than raw strength, arguing for power training as a core longevity medicine intervention.
