📽️ Can NVIDIA help solve aging? That question became Rentosertib. Not starting from a disease. Starting from aging biology. PandaOmics identified TNIK as a target connecting aging and fibrosis. Generative chemistry designed the molecule. Target to preclinical candidate in 18 months. Phase 1, Phase 2A, now Phase 3. And...

Worth keeping in view: the dose with the best FVC was not the dose with the strongest clock shift, which is why the lung and the clocks are still tangled.

Question: are you or are other companies applying your protocol on measuring aging with other drugs? I wonder about metformin, GLP-1, rapamycin in testing for these biomarkers?

New episode with Dr. Steve Horvath (Prof Steve Horvath), a pioneer in the field of epigenetic aging clocks. Steve developed the original Horvath clock, one of the first tools to show that DNA methylation carries a remarkably reliable signal of aging across human tissues. In this episode, he explains what biological clocks actually measure, why different clocks can disagree, and how to interpret a biological-age result without treating it like a literal lifespan forecast. We talk about chronological age vs. biological age, and we also get into the intervention evidence on exercise and VO2 max, calorie restriction, omega-3s, vitamin D, multivitamins, and weight loss/GLP-1 therapy, among other topics! The big theme is that biological clocks can be useful dashboards, but they are not diagnoses, fortune-telling tools, or proof that one supplement has reversed aging. This was Steve's second appearance on the podcast and he did not disappoint. You won't want to miss this episode. Links to the episode on all platforms in the comments below.

Twenty years ago, Derya Unutmaz, MD predicted we would reverse aging by 2045. People thought he was crazy. Now, he thinks he was too conservative, and has moved the date up to 2040 because AGI arrived earlier than he expected. I sat down with Derya to ask if such bold predictions are too fatalistic. Is the future guaranteed? Shall we just sit back and wait for AI to save us? Derya disagreed. The golden age for humanity is within our sights, but there is much work to be done. Academia is failing us. If it doesn’t adapt to the pace of progress AI enables, we have no shot at curing aging this century. And we need to invest trillions into collecting the data that superintelligence will need to solve biology. If we pull it off, the future can be brighter than anyone imagines. Watch the full episode below, or look up Free Radicals (Free Radicals) on your favorite podcasting platform. Special thank you to Adam Gries and for hosting us at Vitalist Bay (May 14-17)! Intro AGI arrived early, accelerating the timeline to biosingularity Are we really in the takeoff now? Superintelligence can help us build a world model of biology Aging as the breakdown of biological resilience The case for investing trillions into biological data The economic return on curing aging AI is accelerating science but academics are stuck in the past How AI can liberate humanity from biological constraints Derya’s Human 2.0 dream Testing the latest OpenAI models and rethinking the PhD Agency, jobs, and free will in an AI world Science fiction & Derya’s case for a coming golden age

If you want to meaningfully impact aging in America, start with obesity—few things erode longevity and quality of life as profoundly, accelerating the biological aging process and fueling nearly every major chronic disease. Obesity alone is linked to 13 types of cancer and cuts life expectancy by 3–10 years, depending on severity. It promotes DNA damage and accelerates our fundamental aging process—often measured by epigenetic age. It’s one of the principal differences between the U.S. and many of the world’s longest-lived nations. We’re overfed but undernourished. 60% of all calories Americans consume come from ultra-processed foods that: • Fail to induce proper satiety, pushing us to overeat. • Remain cheaper than whole foods, economically incentivizing the least healthy choices. • Hijack our dopamine reward pathways, reinforcing addictive eating behaviors. This trifecta—no satiety, low cost, and built-in addictiveness—keeps us in a cycle of poor health outcomes and runaway healthcare costs. But caloric excess is only part of the problem—we are also nutrient-deficient. Low omega-3 levels—affecting 80 to 90% of Americans—carry the same mortality risk as smoking. Vitamin D deficiency—easily corrected—compromises immune function, cognition, and longevity. Nearly half of Americans don't get enough magnesium—impairing DNA repair and increasing the risk of cancer. We are not solving these problems—we are medicating them. The average American over 65 takes five or more prescription drugs daily—stacking interactions that compound in unpredictable ways. We must start treating physical inactivity as a disease. It carries the same mortality risk as smoking, heart disease, and diabetes. Going from a low cardiorespiratory fitness to a low normal adds 2.1 years to life expectancy. By age 50, many Americans have already lost 10% of their peak muscle mass. By 70, many have lost up to 40%. This isn’t just about looking strong. It’s about survival. • Higher muscle mass means improved insulin sensitivity - it means a 30% lower mortality risk. • Grip strength is a stronger predictor of cardiovascular mortality - the number one cause of death in the United States - than high blood pressure. • The strongest middle-aged adults have a 42% lower dementia risk. And yet, we treat resistance training as optional. It is not. It is the most powerful intervention we have against aging including increasing muscle mass, strength and bone density. Hip fractures alone kill 20–60% of older adults within a year. This is a death sentence we can prevent with resistance training - which has been shown to lower fracture risk by 30-40%. The current RDA for protein is too low for older adults. Studies have shown when it's increased by half this reduces frailty by 32%, while doubling it, combined with resistance training, increases muscle mass by 27% and strength by 10% more than training alone. If we want to prevent muscle loss and frailty, we must update our protein recommendations and prioritize strength training. We must foster a culture of American exceptionalism built on daily, effortful exercise. Not as an afterthought. Not as a luxury. But as a non-negotiable foundation for aging, but also clear thinking, resilience, and even leadership. The body and brain are not separate. The consequences of poorly regulated blood sugar, sedentary living, and muscle loss are not just physical—they affect cognition, judgment, and resilience. We cannot medicate our way out of what we have behaved our way into. Grateful for the chance to share my voice at the Senate Aging Committee (Senate Aging Committee). A special thank you to Senator Rick Scott (Rick Scott) for making this opportunity possible.

Forget Everything You've Been Told. Dr. Mark Hyman Says It's Possible to Reverse Diabetes, Heart Disease, and Alzheimer's We've been told Alzheimer's is incurable. A life sentence. But what if that's a relic of a broken, outdated medical model? Dr. Hyman reveals that while Big Pharma has spent over $2 billion on 400+ failed drug trials—resulting only in marginally effective, expensive treatments—a different path has proven radically successful. Aggressive lifestyle intervention can not only slow Alzheimer's... it can reverse it. This isn't speculation. It's published data from landmark trials like FINGER and POINTER. Pioneers like Dr. Richard Isaacson are demonstrating that by addressing diet, exercise, stress, sleep, and metabolic health, we can change the course of the disease. The key? Early detection. With new blood tests for Alzheimer's biomarkers, we no longer have to wait for symptoms like forgetting keys. We can see the warning signs and intervene when it matters most. Why isn't this front-page news? Dr. Hyman calls it a "medical paradigm shift." Most of medicine still operates in a "flat world," diagnosing by symptoms. The future is understanding the body as an integrated system. The implications are staggering. This systems-based approach applies to all chronic diseases—diabetes, heart disease, and even aging itself. By targeting the root causes of aging (inflammation, mitochondrial health, microbiome), we're not just adding years to life, but life to years. The system is ossified. But the science is clear. The power to prevent and reverse chronic disease is increasingly in our hands. It's time for medicine to catch up.

Friedberg: New study shows enzyme reverses skin age from 70+ years to 31 Chamath: That’s a $2T market. Did Scientists Just Discover How to Reverse Skin Aging!? “CML is kind of the predominant molecule that gets formed in this extracellular matrix that's driving aging, and nothing breaks it down. So these scientists set out to try and create an enzyme, an enzyme is a protein that breaks something down, that can break down CML. And so these guys kind of went out and they took the target, which is CML, and tried to figure out, ‘Okay, how do we actually degrade CML, clear that extracellular matrix, and reverse aging?’ They started to test it on the proteins that we would find in our body, casein, collagen, retinal proteins, which are in your eye, hemoglobin, and they were able to get rid of 52 to 97% of the CML, just degrade it away. And then they found several sites where they were able to degrade over 90%. And then they took actual human skin from elderly patients that had donated their skin, and they put this enzyme onto that skin, and they were able to eliminate 55% of the CML on the skin, basically reverse the skin's age down to the age of a 31-year-old, this is from greater than 70-year-old patients, just by putting this enzyme on the skin. And so it's kind of a groundbreaking demonstration of combination of AlphaFold, what's called directed evolution, where you change the order of the DNA that changes the structure of the protein to test different proteins, do high throughput screening, and ultimately make a novel protein that doesn't exist in nature today that can do something pretty profound for human health.” Chamath: “It will be a trillion-dollar market. If you can create a cream…” Friedberg: “I mean, dude, if you could put this enzyme literally on your skin and have it absorb in…” Chamath: “Game over. That alone is $2 trillion.”

David Sinclair just announced at the World Government Summit that next month (March 2026), human clinical trials begin — the first in history to test whether we can reverse aging and cure diseases. His core claim: Aging isn't wear-and-tear like a car; it's like scratches on a CD. DNA is the music, but in old age, cells can't read it correctly — leading to confusion, wrong proteins, and disease. The breakthrough? They can "polish the CD" via partial epigenetic reprogramming (using Yamanaka factors like OSK) to restore youthful gene expression without altering DNA itself. Science nugget: In lab and animal studies (published 2020–2025), Sinclair's team reversed epigenetic age by up to 75% in six weeks in mouse optic nerves, restoring vision in blind animals. The approach reactivates youthful gene patterns while avoiding full cellular reprogramming risks like tumors. Current status: The FDA cleared Life Biosciences' Phase 1 trial (ER-100, Sinclair co-founded) in January 2026 for safety in patients with optic neuropathies (e.g., glaucoma, NAION). Enrollment starts soon, with initial results expected by late 2026/early 2027. This targets eye disease first — not whole-body aging — but success could open doors to broader rejuvenation. Sinclair envisions a future where kids with cancer gather under gentle plasma lights that shatter tumors painlessly, one cell at a time. Sci-fi becoming science fact? Are you hopeful this trial delivers — or skeptical it's overhyped?
