People hate inflation. It undermines faith in the government so people obstruct policies that require faith in the state, like nuclear power, and in democracies it drives them to vote for extremist parties. Ben and Pieter sit down with economic historian Mark Koyama and discuss the fallout of historical inflation crises from the Roman Empire to Weimar Germany. Ben reveals his hidden libertarian 'Gold Bug' tendencies. 

In the mid twentieth century, nuclear power was meant to be the cheap and clean energy of the future. Now, nuclear power is expensive, maligned and unpopular. Ben, Sam and Alex discuss what went wrong in most of the world and, surprisingly, what went right in France. Ben delivers a radioactive hot take that meltdowns aren't so bad after all.

Hepatitis B is a tiny virus that causes hundreds of thousands of deaths from liver disease and cancer each year. The vaccine against it became the first of many milestones: it was the first viral protein subunit vaccine, the first recombinant vaccine, and the first vaccine to prevent a type of cancer. 

In this episode, Jacob and Saloni follow the trail of strange jaundice outbreaks that scientists traced to a stealthy liver virus, how scientists turned one viral surface protein into a lifesaving shot for newborns, and how it was all built upon breakthroughs in immunology.

Before vaccines became routine, they were risky experiments. In this episode, Jacob and Saloni travel back to the world of smallpox, cowpox, and cow-based “vaccine farms” to see how scientists stumbled toward the first vaccines against infectious diseases: smallpox, rabies, TB, polio, and more. Through the stories of milkmaids and aristocrats, secret lab notebooks, microscopes and cell culture, they explore how trial and error turned gruesome folk practices into the science of immunization, and how it all began with a single pustule.

The YIMBY movement is divided about whether there is a tradeoff between building more homes and building beautifully. Ben, Sam and Samuel talk about how aesthetic regulations can make building more popular by generating goodwill from the public and decreasing appetite for historic preservation and how one can differentiate between good-faith complaints and pretextual arguments that make buildings economically unviable.

Why are birth rates plummeting across the developing world? Why should we even care about the baby bust? Where can we find the most elastic baby? Jesús Fernández-Villaverde, Professor of Economics at the University of Pennsylvania, explains why Japan’s decline might be the best case scenario, the problems with childcare subsidies, why you shouldn’t study David Hume, and why the real fertility crisis isn't in rich countries.

You can find Jesús on Twitter (https://x.com/JesusFerna7026/) where he tweets about on economics, history, and demographics, and read about Korea's fertility crisis in the new print edition of Works in Progress http://worksinprogress.co/print.

Artificial intelligence is transforming how we discover and develop new medicines. But how far can it really take us? In this episode, Jacob and Saloni trace the path of drug development from discovery to testing, manufacturing, and delivery. They explore where AI could speed things up, and where it still hits the limits of biology, data, and economics. They ask what it would take, beyond algorithms, to actually cure and eradicate diseases.

How can we build new cities in America? Which historical president is Trump most like? Why did immigration policy go so wrong? Sam and Pieter sit down with Congressman Jake Auchincloss to discuss the politics of the Abundance movement. They talk about Auchincloss's fight against free parking, regulating big tech, the success of YIMBYs, and why curing Alzheimers should be the next American moonshot project.

What if you could design a protein never seen before? 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.

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.
