Aging is more than disease—it’s the steady decline of function. In this episode of Longevity by Design, Dr. Gil Blander speaks with physicist-turned-biotech innovator Dr. Peter Fedichev about why resilience, not diseases, holds the key to longer lives.

Peter explains how his background in theoretical physics shaped his approach to biology and aging. He outlines why startups, not large institutions, are now leading innovation in longevity science. Drawing from physics, he describes aging as a series of “jumps” between states, each leaving the body more fragile.

The discussion moves from the limits of current drugs to the promise of new approaches. Peter argues that reducing fluctuations and increasing molecular fidelity could unlock far greater gains in healthspan and lifespan. Listeners gain a fresh lens on what drives aging, where the real breakthroughs may come from, and why the next frontier in longevity will require rethinking the problem altogether.

In this episode, Dr. Gil Blander welcomes Dr. Haim Cohen to Longevity by Design to explore his revolutionary approach to understanding aging. Haim's team analyzed acetylation sites across 107 mammalian species, creating its most extensive comparative study. This computational approach revealed specific post-translational modifications that evolved exclusively in long-lived animals.

The research identifies critical pathways where evolution engineered longevity solutions. These acetylation changes affect DNA repair, cell cycle regulation, and mitochondrial function. Unlike traditional aging research focusing on single pathways like mTOR or caloric restriction, Haim's unbiased screening simultaneously reveals multiple longevity targets. Evolution provided a natural laboratory for testing anti-aging modifications over millions of years.

The findings offer exciting therapeutic possibilities for human longevity. Haim's team is now creating transgenic mice to test whether mimicking these evolutionary changes can extend lifespan in the lab. This research suggests humans could potentially "accelerate evolution" by implementing modifications that nature has already proven effective in whales, elephants, and other long-lived species.
