AI redesigns cell “youth switch” — 50x more powerful

RetroBiosciences and OpenAI used a new biology LLM, GPT-4b micro, to re-engineer Yamanaka factors — proteins that reset cells to a younger state.

‍

- The AI-designed versions boosted reprogramming efficiency 50x in lab tests

- Past factors were too weak and risky for safe therapies — these new ones look far more practical

- Could enable controlled rejuvenation of human cells, opening the door to anti-aging treatments

Most people still underestimate how fast AI may crack the biology of aging.
