In the nineteenth century, cities often grew a thousandfold while increasing wages, the size of homes, and delivering great public goods like electricity and plumbing to their people. What made them so extraordinary? They had a hybrid of laissez-faire and top-down control. Landowners could build almost anything they liked but street networks were laid out with near-Soviet thoroughness decades in advance. Transport and utilities, meanwhile, ran as regulated monopolies. They were funded by users, turned a profit, but prices were controlled.Samuel, Ben and Aria discuss what made this system work and why it was dismantled. 

Malaria is caused not by a virus or bacterium, but by a complex, shape-shifting parasite that has evolved alongside us for millennia. This has made vaccine development a brutal challenge.In this episode, Jacob and Saloni are joined by Katharine Collins, who co-invented the second malaria vaccine, called R21, during her PhD. They discuss the gruelling process of reverse-engineering a vaccine and eureka moments along the way. They ask whether the biggest barriers to new vaccines are scientific or financial, and what it will take to finally eradicate one of natureʼs most vicious killers.Hard Drugs is a podcast from Works in Progress about medical innovation presented by Saloni Dattani and Jacob Trefethen.Timestamps:00:00 Introduction05:08 Our favourite parasites10:12 How to invent a vaccine during your PhD34:18 Why is it called the R21 vaccine?37:32 Moving from the bench to billions of doses41:43 The vicious life cycle of malaria parasites46:15 Malaria research IN MICE53:03 The murderer in malaria research55:51 Would you volunteer to get infected by malaria?1:08:21 Why did the first malaria vaccine take so long?1:18:26 Could we have had the vaccine sooner?1:40:48 Vaccine versus vaccine: which one’s better?1:46:53 If we did this again today, could we make better vaccines?2:04:55 Conclusion and our reasons for pessimism and optimismYou can watch or listen on YouTube, Spotify, or Apple Podcasts.Saloni’s substack newsletter: https://www.scientificdiscovery.dev/Jacob’s blog: https://blog.jacobtrefethen.com/ Acknowledgements:Aria Babu, editor at Works in ProgressGraham Bessellieu, video editorAlice Edwards, captionsAbhishaike Mahajan, cover artAtalanta Arden-Miller, art directionDavid Hackett, composerWorks in ProgressThesisKatharine Collins (2014).

The Trump administration wants to bolster traditional art. Their attempt to revive sculpture, a mass statue-building program, is doomed. America doesn’t have the sculptors, foundries, and workers to make hundreds of bronze or marble sculptures. North Korea would be in a much better position.Sam and Samuel sit down with our Art Director, Atalanta, a sculptor by training, and talk all things sculpture. They discuss how art education has become de-skilled, how sculpture has always been the best art form for mass production and the surprising places the tradition has been kept alive. 

Generations of microbes evolve in hours, not millennia. By speeding up Darwin’s clock, scientists have watched evolution happen in real time, and it’s changed how we understand natural selection.
