Love it or hate it, the freedom to say obnoxious and subversive things is the quintessence of what makes America America. But our say-almost-anything approach to free speech is actually relatively recent, and you can trace it back to one guy: a Supreme Court justice named Oliver Wendell Holmes. Even weirder, you can trace it back to one seemingly ordinary 8-month period in Holmes’s life when he seems to have done a logical U-turn on what should be say-able. Why he changed his mind during those 8 months is one of the greatest mysteries in the history of the Supreme Court. (Spoiler: the answer involves anarchists, a house of truth, and a cry for help from a dear friend.) Join us as we investigate why he changed his mind, how that made the country change its mind, and whether it’s now time to change our minds again.

Last summer, at a hospital in England, a man in his 70s being treated for complications with cancer tested positive for covid-19. He had lymphoma, and the disease plus his drugs weakened his immune system, making him particularly susceptible to the virus. He wasn’t too bad off, considering, and was sent home. That was Day 1. This is the story of what the doctors witnessed, over the course of his illness: the evolution of covid-19 inside his body. Before their eyes, they get a hint of what might be to come in the pandemic. This episode was reported by Molly Webster. Special thanks to Ravindra Gupta, Jonathan Li.

It was the early 80s, the height of the Cold War, when something strange began happening off the coast of Sweden. The navy reported a mysterious sound deep below the surface of the ocean. Again, and again, and again they would hear it near their secret military bases, in their harbors, and up and down the Swedish coastline. After thorough analysis the navy was certain. The sound was an invasion into their waters, an act of war, the opening salvos of a possible nuclear annihilation. Or was it? Today, Annie McEwen pulls us down into a deep-sea mystery, one of international intrigue that asks you to consider the possibility that maybe, just maybe, your deepest beliefs could be as solid as...air. This episode was reported by Annie McEwen and produced by Annie McEwen, Matt Kielty, and Sarah Qari, with sound design by Jeremy Bloom. Special thanks to Bosse Lindquist.

What if someone asked you to get infected with the COVID-19 virus, deliberately, in order to speed up the development of a vaccine? Would you do it? Would you risk your life to save others? For months, dozens of companies have been racing to create coronavirus vaccines. Finally, three have done it. But according to the experts, we’re not out of the woods yet; we’ll need several vaccines to satisfy the global demand. One way to speed up the development process is a controversial technique called a human challenge trial, in which human subjects are intentionally infected with the virus. Senior correspondent Molly Webster gets the lowdown from Public News Service reporter Laura Rosbrow-Telem and then tracks down some of the tens of thousands of people who have volunteered to participate in a challenge trial. Special thanks to Jonathan Miller. This episode was reported by Molly Webster and Laura Rosbrow-Telem and produced by Molly Webster and Pat Walters.

When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China’s technological renaissance almost didn’t happen. And for one very basic reason: The Chinese language, with its 70,000 plus characters, couldn’t fit on a keyboard. Today, we tell the story of Professor Wang Yongmin, a hard headed computer programmer who solved this puzzle and laid the foundation for the China we know today. This episode was reported and produced by Simon Adler with reporting assistance from Yang Yang. Special thanks to Martin Howard.

As scientists have been scrambling to find new and better ways to treat covid-19, they’ve come across some unexpected allies. Invisible and primordial, these protectors have been with us all along. And they just might help us to better weather this viral storm. To kick things off, we travel through time from a homeless shelter to a military hospital, pondering the pandemic-fighting power of the sun. And then, we dive deep into the periodic table to look at how a simple element might actually be a microbe’s biggest foe.

Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It’s a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies.
