What if you could design a protein never seen in nature? In this episode, Jacob and Saloni explore how researchers are using new tools like RFDiffusion, AlphaFold, and ProteinMPNN to ‘hallucinate’ entirely novel proteins: designing them from scratch to solve problems evolution hasn’t tackled. They talk about how these technologies could transform medicine, agriculture, and materials science. Along the way, they reflect on the surprising ways AI is changing the process of science itself.

Hard Drugs is a new podcast from Works in Progress and Open Philanthropy about medical innovation presented by Saloni Dattani and Jacob Trefethen.

Nature didn’t evolve all the proteins we need, but maybe artificial intelligence can help. Jacob and Saloni explore how tools like AlphaFold and ProteinMPNN are helping researchers re-engineer proteins, to make them safer, more stable, and more effective. They talk about how new technologies could help make a long-sought vaccine against Strep A, which causes scarlet fever and rheumatic heart disease, and how similar tools have already led to breakthroughs against COVID and RSV.

A hundred years ago, insulin was scraped from pig pancreases. Today, it’s made by bacteria in giant tanks. In the second part of a mini series on proteins, drug development and AI, Saloni tells the story of how insulin went from a crude animal extract to the first genetically-engineered drug, kickstarting the biotech industry along the way.
