Hard Drugs
Hard Drugs is a podcast hosted by Saloni Dattani and Jacob Trefethen that explores medical innovation. It examines how to accelerate and scale the development of new treatments. The show also looks at how to ensure lifesaving tools reach the people who need them most. It is produced by Works in Progress.
Episodes
Can we switch off diseases?
What if treating diseases was as simple as telling your cells to stop making a harmful protein? That’s the premise of siRNA, a technology that silences genes without changing DNA. Just a single dose of siRNA can last for months. Better, it can be reprogrammed to silence a different gene or mutation by simply switching its sequence.In this episode, Jacob and Saloni explore why it took so l
Are miracle drugs hiding in plain sight?
GLP-1 drugs like Ozempic and Mounjaro have transformed the treatment of obesity as well as diabetes, help treat heart disease, kidney disease, sleep apnea, and maybe even Alzheimer’s. But they are far from the only medicine with more than one use. Aspirin, colchicine, minoxidil, and Viagra were all found to treat more conditions than expected, and about a third of drugs end up with a seco
Inventing the second malaria vaccine with Katharine Collins
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 vacci
Should everyone be taking statins?
Heart disease is the leading cause of death worldwide, but it’s also one of medicine’s biggest success stories. Since the 1950s, the risk of dying from cardiovascular disease has fallen dramatically, thanks to public health efforts, emergency care, medical innovation, and surgeries.In this episode, Jacob and Saloni explore the cholesterol revolution: from statins discovered in fungi to ne
The first cancer vaccine
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 sc
The history of vaccines
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 cu
Will AI solve medicine?
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
The art of protein design with AI
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 scien
Hacking proteins with AI
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 he
100 years of insulin in 15 minutes
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.Hard Drugs is a new podcast from Works in Progres
Proteins: Weird blobs that do important things
This episode kicks off a mini-series on proteins, drug development and AI. Saloni and Jacob explore the world of proteins, including how proteins fold into complex shapes, why that complexity matters and how crowded and dynamic the inside of a cell really is; and they exchange surprising statistics about proteins.Hard Drugs is a new podcast from Works in Progress and Open Philanthropy abo
Lenacapavir: The miracle drug that could end AIDS
Lenacapavir is a new HIV drug that blocks infections with an efficacy rate of nearly 100%, and it could completely change the fight against HIV worldwide. Saloni and Jacob talk about the development and prospects for this new drug, as well as the history of HIV, the initial discovery of retroviruses, and how HIV was transformed from a death sentence to a manageable condition.Hard Drugs is
