In a Nutshell

The world's first age-reversal trial (ER-100) has begun, testing epigenetic reprogramming via OSK genes to restore vision in glaucoma and optic nerve stroke patients, with the first participant dosed and early results promising. The eye serves as both a window to brain aging—via AI retinal scans that predict mortality risk—and an ideal entry point for whole-body rejuvenation therapies. Daily interventions include caloric restriction, violet light exposure, lutein/omega-3 supplementation, and avoiding smoking/alcohol to slow age-related vision loss.

The eyes are not just a separate sensory organ. They are part of the brain. Reversal of aging isn't just for the eye. It seems to work across the entire body of animals too.

David Sinclair is a scientist and professor working on understanding why we age and discovering new ways to slow and even reverse the aging process. He shares an insider look at the latest from his lab, the field, and what's just around the corner.

The world of vision science is moving really fast with exciting developments. Matthew Lelant is a professor of journalism at Utah State University and recently earned a PhD in climate science. He is also co-author on the book Lifespan.

Today's conversation focuses on the eye, how the retina and optic nerve function, and how problems like glaucoma, cataracts, and age-related macular degeneration develop. The episode also covers daily choices, lifestyle habits, and preventative strategies to protect sight in the long run.

David Sinclair is 57 years old. Many people experience vision problems starting in childhood with nearsightedness, or around age 40 when reading gets harder, screens get blurrier, or night driving becomes more difficult.

David Sinclair recently co-authored a review on oculomics and AI looking at how artificial intelligence can scan the micro-architecture of the back of the eye. By using advanced AI to read subtle, hidden patterns in the retina, a simple non-invasive eye scan can estimate true biological age, track brain health, and predict risk for future diseases.

Aging is in part a loss of biological information, and restoring that information could help cells remember how to function like they're young again. This is the idea behind ER-100, the first cellular rejuvenation therapy using epigenetic reprogramming to receive FDA clearance to enter human clinical trials.

ER-100 or epigenetic reprogramming 100 uses controlled expression of OSK, three of the Yamanaka genes, to try and help damaged retinal nerve cells recover more youthful function. The Life Biosciences trial is testing the safety and tolerability of ER-100 in people with blindness caused either by glaucoma (due to eye pressure) or by NAION (a stroke in the back of the eye).

Earlier this year, the first participant received their first dose of ER-100. The trial is going well.
