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 is period scooping? And other menstrual hacks you should think twice about

Period scooping sounds like something you would only hear in a biology lab, not while doom-scrolling TikTok. Yet earlier this year, videos claiming you can “scoop out” your period to avoid the mess and shorten the whole thing racked up millions of views. In this episode, we hear from Sally King, a visiting fellow at King’s College London, about why you can't shorten your period, and why you need to be careful about upsetting the pH balance of your body. She also gives us her perspective as a menstrual physiologist on other period hacks, including menstrual blood face masks, and drinks that some influencers say can shorten your period.

Australia's 'barking mad' bet on nuclear submarines

The multi-billion dollar AUKUS defence deal between the US, UK and Australia is one of the most significant in our modern history. The three countries wanted to curb China’s growing military presence in the Indo-Pacific. To do it, Australia was going to get new nuclear-powered submarines. But in the five years since the agreement was first announced, it’s been anything but smooth sailing. In this week's episode of The Conversation Weekly, we speak with Hugh White, a security and defence analyst at the Australian National University, to explore how the secretive deal was struck and why it's proving so controversial. Read more from Hugh White and his take on the AUKUS debate here. This episode was written by Justin Bergman and Isabella Podwinski was the executive producer.

Does light therapy work? The science of stroboscopic stimulation

Light therapy sounds wholesome. Sit in front of a lamp. Feel better. But nowadays, it can also mean strapping on a flashing mask and watching your own brain generate kaleidoscopic hallucinations behind closed eyelids. In this episode, host Katie Edwards tries on a stroboscopic light mask being promoted by celebrities including Jennifer Aniston and Rosamund Pike to find out what happens. And David Schwartzman, a research fellow at the Sussex Centre for Consciousness Science at the University of Sussex, explains how stroboscopic light produces hallucinations in the brain, and how it's currently being trialled to treat conditions like depression.

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.

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.

Ratko Mladić: the war criminal who became a martyr for Bosnian Serbs

To most of the world, former Bosnian Serb military general Ratko Mladić was a brutal war criminal whose actions during the Bosnian War killed thousands. For others, he was a martyr who defended the Serbian people. In late August, the 84-year-old died while serving a life sentence in The Hague for war crimes and crimes against humanity. He was laid to rest in Belgrade earlier this week with full military honours - a move which angered the families of the victims of his crimes. On this week's episode of The Conversation Weekly, why a war criminal being celebrated by some as a hero and how this is reopening old wounds in one of Europe’s most divided regions. Read Olivera’s Simic’s article on Mladic’s death and what it means for Bosnia and Herzegovina here. This episode was written and produced by Isabella Podwinski and Justin Bergman.

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.

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.

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.
