In this episode of The Cognitive Revolution, Nathan explores the cutting-edge intersection of AI and biology with Stanford assistant professor Brian Hie. Discover how AI is revolutionizing our understanding of biological systems and creating new possibilities for interventions. Brian discusses his groundbreaking papers on hybrid AI architectures, the surprising capabilities of language models trained on DNA sequences, and AI-guided evolution of antibodies. Join us for an insightful journey into the future of AI in biology, touching on biosecurity, drug discovery, and the challenges of interpreting AI models in biological contexts.
