Just about the hottest thing in longevity science right now is partial reprogramming - using Yamanaka factors to rewind the biological clock in our cells. Billion-dollar giants like Altos, Retro and New Limit are betting on it.

But in this episode a far smaller player, Shift Bioscience, argues that the field may be looking in the wrong place. CEO Daniel Ives explains how his team used AI-powered virtual cells to uncover a single gene that seems to match OSK-level rejuvenation without the tumor risk that haunts classical reprogramming - and why their just-released data could change the game for aging research.

🔍 In this conversation

✅ Daniel’s journey from mitochondrial PhD work to founding Shift Bioscience.

✅ Why Yamanaka-factor–based partial reprogramming excites the field and why it’s inherently risky.

✅ Epigenetic clocks 101 — Horvath, single-cell versions, and what they really measure.

✅ Building AI “virtual cells” (transformers / GNNs) to run millions of in-silico experiments.

✅ Discovery of new rejuvenation factor sets - including SB000, a lone gene that rejuvenates without inducing pluripotency.

✅ Early wet-lab validation across fibroblasts & keratinocytes; next-step mouse studies already under way.

✅ How inhibition targets (not just over-expression) could slash timelines from 15 years to ~5 years.

✅ Mapping a “risk landscape” of age-linked diseases and why fibrosis may be the fastest clinical entry point.

✅ Funding Shift: from personal redundancy money to a $16 M seed and the next raise.

✅ Timelines, escape-velocity hopes, and where cryonics still fits.

✅ What Daniel would ask Jeff Bezos, and why the pharma ecosystem needs to “plug in” now.
