概要

What if AI could design proteins to help your immune system find and kill cancer cells? That's not a hypothetical — it's what 28 teams across 40 countries attempted in the Bits-to-Binders Challenge, an open-science competition organized by PhD students at the University of Texas at Austin. In this episode, Ron sits down with three of the organizers — Clay Kosonocky, Daryl Barth, and Aaron Feller — to unpack how they pulled off one of the most ambitious student-led experiments at the intersection of AI and biology. Together, they submitted 12,000 AI-designed protein sequences to bind to a cancer target called CD20, then validated the results in real biological assays. The conversation covers the 100-year history of protein folding, how AlphaFold changed everything, why AI biology can't just rely on benchmarks, what a CAR-T cell actually does, and what a 7% hit rate tells us about where the field really stands. Plus: open source science, the verification gap between digital predictions and wet lab reality, and why a global team of strangers working together might be the most hopeful signal of all. 00:00 Intro & Why AI Protein Design Matters 02:38 Why Protein Folding Is So Important 04:47 What AlphaFold Changed 07:59 From Predicting Proteins to Designing Them 11:10 The Rise of AI Protein Design 13:27 AI Skepticism in Biology 15:34 Why Wet Lab Validation Still Matters 20:36 Inside the Bits-to-Binders Challenge 22:05 Designing CAR-T Cell Proteins 26:57 Why Most Designs Failed 31:12 Open Source Biology & Global Collaboration 33:37 Competition Winners & Best Results 35:39 Final Takeaways on AI + Biology
