Summary

In this World Science Festival conversation, Brian Greene interviews Nobel laureate David Baker about the revolutionary field of protein design. Baker explains how proteins are the molecular machines of life, encoded by genes, and how their function depends on their 3D structure. He describes the historical challenge of predicting protein structure from sequence, a problem tackled by computational methods and, more recently, deep learning. Baker highlights the shift from studying naturally evolved proteins to designing entirely new ones with custom functions, a field he pioneered. He discusses the use of the Rosetta software and AI tools like AlphaFold, and the potential applications in medicine, materials science, and environmental remediation. The conversation also touches on Baker’s unconventional academic path, the importance of broad scientific curiosity, and the philosophical implications of creating new life-like molecules. Throughout, Baker emphasizes the transition from discovery to design, and the immense possibilities that arise when we can write the code of life.
