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.

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 cracking my neck and knuckles bad?

Joint cracking is one of those habits most of us acquire without thinking about it. In our third episode, we turn our attention to one of the body’s most common and least understood noises. Knuckles, backs, knees and necks all feature, along with the enduring warning many of us grew up with: “Stop cracking your joints, you’ll get arthritis.” Is there any truth in it? And why can cracking feel so strangely satisfying? Hosts Katie Edwards and Dan Baumgardt turn this week to Clodagh Toomey, a specialist in musculoskeletal injury and chronic lifestyle-related diseases such as osteoarthritis, to give you the science behind the myths.

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.

The Super Bowl that kickstarted prop betting in America

Super Bowl Sunday is the biggest night in American sports. A popular destination to watch – and bet – on the Super Bowl is Las Vegas, Nevada. And it was in Las Vegas, ahead of the 1986 Super Bowl between the Chicago Bears and the New England Patriots, that one enterprising casino would kickstart a new direction in American sports gambling: prop betting. It offered odds not just on the result of the game, but on the outcome of an individual event within it – whether one defensive player called William Perry, nicknamed The Refrigerator, would score a touchdown. Today, as American sports face multiple gambling scandals, we speak to John Affleck, Knight Chair in sports journalism and society at Penn State, about that 1986 Super Bowl, the history of prop betting, and why he believes its explosion is threatening the integrity of professional sports in the US. This episode was written and produced by Katie Flood with editing help from Mend Mariwany. The executive producer is Gemma Ware. Mixing by Michelle Macklem and theme music by Neeta Sarl.

How Iran shut down the internet

On January 8, as thousands of Iranians took to the streets in nationwide protests, the government cut off the internet. Under cover of digital darkness, the Iranian regime launched a brutal and deadly crackdown against anti-government protesters. After three weeks of internet blackout, reports from web traffic monitor Netblocks suggest that the internet is slowly coming back online but predominantly for government-approved users. Yet for most of the shutdown, banks and some local government websites and apps still worked. And that’s because Iran is developing its own, national internet, cut off from the rest of the world. In this episode, we speak to Amin Naeni, a PhD candidate researching digital authoritarianism at Deakin University in Australia, about how Iran built one of the world’s most sophisticated systems of digital control.

A lost US military base under Greenland's ice sheet

In the summer of 1959, a group of American soldiers began carving trenches in the Greenland ice sheet. Those trenches would become the snow covered tunnels of Camp Century, a secret Arctic research base powered by a nuclear reactor. Camp Century operated for six years, during which time the scientists based there managed to drilling a mile down to collect a unique set of ice cores. But by 1966, it had been abandoned, deemed too expensive and difficult to maintain. Today, Donald Trump’s territorial ambitions for Greenland continue to cause concern and confusion in Europe, particularly for Denmark and Greenlanders themselves who insist their island is not for sale. One of the attractions of Greenland is the gleam of its rich mineral wealth, particularly rare earth minerals. Now that Greenland’s ice sheet is melting due to global warming, will this make the mineral riches easier to get at? In this episode, we talk to Paul Bierman, a geologist and expert on Greenland’s ice at the University of Vermont in US. He explains why the history of what happened to Camp Century – and the secrets of its ice cores, misplaced for decades, but now back under the microscope – help us to understand why it’s not that simple.

Theory of everything: do we really need one?

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everything? And are we anywhere near achieving one? Featuring Vlatko Vedral, a professor of physics at the University of Oxford and Chanda Prescod-Weinstein, an assistant professor in physics and astronomy and core faculty in women's and gender studies at the University Of New Hampshire. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Model minority blues: The mental health consequences of being a model citizen

The pandemic has taken a toll on our collective mental health. But according to a recent Statistics Canada report, South Asians reported a steeper decline than any other diaspora in Canada. Why? The idea of being a model minority – of having to live up to exacting high standards – is a big part of it. Two long-time researchers and activists join Vinita for an intimate conversation about that and other reasons why South Asians are struggling so badly, and what can be done about it. Maneet Chahal is co-founder of SOCH, one of the few mental health organizations specifically for South Asians. Satwinder Bains is the director of the South Asian Studies Institute and professor of social cultural media studies at the University of the Fraser Valley.

The Making of an Autocrat: co-opt the military

In November, six Democratic lawmakers recorded a video directed at members of the US military and intelligence agencies. In it, they issued a blunt reminder: "The laws are clear: you can refuse illegal orders. […] You must refuse illegal orders." The lawmakers were issuing the warning against the backdrop of US airstrikes on boats off the coast of Latin America the Trump administration claims are suspected drug runners. Many Democrats and legal experts, however, argue these strikes are illegal. Since returning to office, Trump has successfully expanded his power over his own party, the courts and the American people. Now, like many autocrats around the world, he’s trying to exert control over the military. In the final episode of The Making of an Autocrat, Joe Wright, a political science professor at Penn State University, says: "I am very concerned that getting the military to do illegal things will not only put US soldiers at more risk when they do engage in international missions in the future […] it’s a first step to using the military to target domestic political opponents. That’s what really worries me." This episode was written by Justin Bergman and produced and edited by Isabella Podwinski and Ashlynne McGhee. Sound design by Michelle Macklem.
