Tonsils, kidneys and gall: why your body makes stones

The human body, it turns out, is surprisingly good at making stone. Give it enough time and the right conditions and it will go about crystallising minerals, hardening secretions and, in rare cases, turning tragedy into rock. Gallstones. Kidney stones. Tonsil stones. Salivary stones. And, in one of the strangest and saddest corners of medical history, stone babies. In our second episode, hosts Katie Edwards, a health editor at The Conversation, and Dan Baumgardt, a practising GP and lecturer in health and life sciences at the University of Bristol, take a tour through the stony side of human anatomy and ask why this keeps happening, where these stones form and which ones you actually need to worry about. They talk to Adam Taylor, a professor of anatomy at Lancaster University, who has spent years studying stones in both everyday and extraordinary contexts, including a rare genetic condition called alkaptonuria Strange Health is a podcast from The Conversation is an independent, not-for-profit news organisation.

What is the vagus nerve and can you really reset it?

The vagus nerve has become the internet’s favourite body part. On social media, it is everywhere. People hum into their phones, gargle with theatrical enthusiasm, dunk their faces into bowls of ice water and poke at their ears in the hope of “activating” it. So in this episode we focus our attention on the body’s longest cranial nerve and ask a simple question: what does the vagus nerve actually do, and can we really hack it? Hosts Katie Edwards and Dan Baumgardt turn this week to Arshad Majid, a professor of cerebrovascular neurology at the University of Sheffield and an expert in vagus nerve stimulation.

What your body odour says about you

Body odour has a reputation problem. It is often treated as a hygiene failure or a social offence. In reality, it is biology at work, plus a big helping of culture. And yet people online are trying chlorophyll shots to make their BO smell better. Hosts Katie Edwards and Dan Baumgardt discuss what evidence there is behind this, plus some of the health conditions that can affect body odour. And we talk to Mats Olsson, a professor of experimental psychology at the Karolinska Institutet in Stockholm, who studies how humans perceive body odour.

Meet the mites that live on you: from demodex to dust mites and scabies

You are not alone in your own skin. Millions of microscopic creatures live there too. Our skin is home to entire ecosystems of microscopic life. Bacteria and fungi get most of the attention, but mites are there too. Among the most common are demodex mites, tiny eight-legged relatives of spiders that live inside hair follicles and pores, especially on the face. Almost all adults carry them. In this episode we explore what these microscopic housemates are actually doing on our bodies and why the idea of them can feel so unsettling. While demodex may be harmless, there are plenty of other mites that can cause problems, from dust mites, to scabies. Hosts Katie Edwards and Dan Baumgardt turn this week to Alejandra Perotti, professor of invertebrate biology at the University of Reading, who studies the relationship between mites and humans.

Is detoxing your liver worth the hype?

Social media is full of green juices, charcoal supplements, foot patches and seven-day “liver resets”, all promising to purge the body of mysterious toxins and return it to a purer state. But do you really need to detox your liver? In the first episode of Strange Health, hosts Katie Edwards, a health editor at The Conversation, and Dan Baumgardt, a practising GP and lecturer in health and life sciences at the University of Bristol wince and occasionally laugh their way through some of the internet’s most popular detox trends. They also speak to Trish Lalor, a liver expert from the University of Birmingham, whose message is refreshingly blunt: “your body is really set up to do it by itself.” Strange Health is a podcast from The Conversation is an independent, not-for-profit news organisation.

Is time an illusion?

Without a sense of time, leading us from cradle to grave, our lives would make little sense. But on the most fundamental level, physicists aren't sure whether the sort of time we experience exists at all. We talk to three experts and find out if time could potentially be moving backwards as well as forwards. Featuring Sean Carroll, Homewood professor of natural philosophy at Johns Hopkins University, Emily Adlam, postdoctoral associate of the philosophy of physics at Western University and Natalia Ares, Royal Society university research fellow at the University of Oxford. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware. Social media and platform production by Alice Mason, sound design by Eloise Stevens and music by Neeta Sarl. A transcript is available here.

The Making of an Autocrat: recruit an architect

Every autocrat needs a clan of loyalists, strategists, masterminds – these are the figures behind the scenes pulling the strings. They’re unelected and unaccountable, yet they wield a huge amount of power. This is the role Stephen Miller has played for Donald Trump – he is the architect in chief for the second Trump administration. He has so much power, in fact, he’s reportedly referred to as the "prime minister." So who is Stephen Miller? And why are architects so important in helping a would-be autocrat amass power? As Emma Shortis, a Trump expert and an adjunct senior fellow at RMIT University in Melbourne, explains in episode 2 of The Making of an Autocrat: "[Miller] is the kind of brains behind particularly Trump's hardline stances on immigration and the Trump administration's ability to use the levers of power, and expand the power available to the president. I think what Stephen Miller demonstrates and, and history has demonstrated over and over again is that autocrats cannot rise to power by themselves. They often require a singular kind of charisma and a singular kind of historical moment, but they also need architects behind them who are able to facilitate their rise to power." This episode was written by Justin Bergman and produced and edited by Isabella Podwinski and Ashlynne McGhee. Sound design by Michelle Macklem.

The Making of an Autocrat: beat the courts

In democratic systems, the courts are a vital check on a leader’s power. They have the ability to overturn laws and, in Donald Trump’s case, the executive orders he has relied on to achieve his goals. Since taking office, Trump has targeted the judiciary with a vengeance. He has attacked what he has called “radical left judges” and is accused of ignoring or evading court orders. The Supreme Court has already handed the Trump administration some key wins in his second term. But several cases now before the court will be pivotal in determining how much power Trump is able to accrue – and what he’ll be able to do with it. As Paul Collins, a Supreme Court expert from the University of Massachusetts-Amherst, explains in episode 4 of The Making of an Autocrat: "It’s all about presidential power. And that’s really significant because it’s going to enable the president to basically inject a level of politics into the federal bureaucracy that we frankly haven’t really seen before in the US." This episode was written by Justin Bergman and produced and edited by Isabella Podwinski and Ashlynne McGhee. Sound design by Michelle Macklem.

The Making of an Autocrat: hijack a party

We used to have a pretty clear idea of what an autocrat was. History is full of examples: Adolf Hitler, Joseph Stalin, Mao Zedong, along with Vladimir Putin and Xi Jinping today. The list goes on. So, where does Donald Trump fit in? In this six-part podcast series, The Making of an Autocrat, we are asking six experts on authoritarianism and US politics to explain how exactly an autocrat is made – and whether Trump is on his way to becoming one. This episode was written by Justin Bergman and produced and edited by Isabella Podwinski and Ashlynne McGhee. Sound design by Michelle Macklem.

Venezuela's plan to resist a US invasion

In the latest escalation of tensions between the US and Venezuela, the US President Donald Trump ordered a "complete blockade" of sanctioned oil tankers going into and out of Venezuela. His Venezuelan counterpart, Nicolás Maduro, called the move "warmongering threats", and accused the US of trying to steal its resources. In this episode we speak to Pablo Uchoa, a PhD candidate researching Venezuela's military, on how Venezuela has long been preparing for this moment, ever since a failed coup attempt on Maduro's predecessor, Hugo Chávez. This episode was written and produced by Mend Mariwany and Gemma Ware with assistance from Katie Flood. Mixing by Michelle Macklem and theme music by Neeta Sarl. Gemma Ware is the executive producer.
