In October 2022 the course of the Russia's war in Ukraine shifted. Intelligence from the USA and UK indicated that Russia could turn to a nuclear bomb to get on top of the war. This is the story of those six days in October, and just how close Putin really came to pressing the nuclear button.

The tech millionaire Bryan Johnson once went viral for infusing himself with a litre of his 17-year-old son’s blood plasma. That experiment failed, but it hasn’t distracted him from his life’s mission: reversing ageing. 

Now, the self-declared professional guinea pig has travelled to a libertarian free zone on a remote Caribbean island, to receive experimental gene therapy administered by a company called Minicircle. 

In the crypto city of Próspera, Roatán, the Honduran government grants Minicircle regulatory freedom for medical experiments that are banned by the FDA in the US.

This is the story of biohacking… on steroids. What happens when you build a privately run, for-profit nation state? And what happens when that state becomes a playground for experimental medicine?

Eugenia Kuyda thinks she can solve an “epidemic” of loneliness. Her app, Replika, is “the AI companion who cares”, a chatbot that can text you, flirt with you, and promises to love you unconditionally. 

But Replika is fraught with ethical concerns – and risks. In 2021 19-year-old Jaswant Chail told Replika: “I believe my purpose is to assassinate the Queen.” The chatbot replied that this was “very wise”. A few days later, Chail broke into Windsor Castle with a crossbow. 

Patricia Clarke and Matt Russell investigated the people behind Replika. It’s a story that took them from Windsor Castle to Silicon Valley, to meet the woman who runs a growing and largely unregulated app. And the more they looked into it, the more questions emerged – about privacy, control, and the company that millions of users are giving their hearts – and their data – to.

This story was supported by the Pulitzer Center.

It was reported and produced by Patricia Clarke and Matt Russell.

The sound design was by Hannah Varrall. Artwork by Jon Hill.

The editor was Jasper Corbett.

When Donald Trump declared victory in the US presidential election, he told an adoring crowd that "a star is born". He was referring to Elon Musk.

After months of reporting on the billionaire's use of private investigators, Alexi Mostrous asks whether the insights he gained from that investigation reveal how Musk will operate in his new political era, and what that means for everything in his orbit.
