Rowan Cheung on Instagram: "OpenAI has developed a specialized AI model that successfully redesigned Nobel Prize-winning proteins to reverse cellular aging with 50-fold greater efficiency. Working with longevity startup Retro Bio, researchers used GPT-4b micro, a model trained on biological data rather than text, to reengineer Yamanaka factors, proteins that reprogram adult cells into stem cells. The original 2012 discovery converted less than 0.1% of cells over weeks, but the AI-designed versio
