A lot of us reach for music when we’re struggling. Whether we’re going through a breakup or just a rough day, our favorite jams seem to have an almost magical ability to give us relief. But WHY?! What exactly is music doing in the brain that affects how we feel? And how powerful is it? Like, could music actually treat diseases? We dig into these questions with musician, neuroscientist, and professor Dr. Dan Levitin. He wrote a book called “I Heard There Was a Secret Chord: Music as Medicine” all about the incredible neuroscience behind music and how it can help with things like depression, pain and even Alzheimer’s disease. UPDATE 11/6/26: A previous version of this episode incorrectly suggested that aphantasia was discovered recently. The phenomenon was first described in the late 19th century, although the term was only coined in 2015. The episode has been updated. This episode does mention depression.

We’re hearing a ton about the marvels of testosterone from influencers, celebrities, and even government officials. They say we should be thinking about our T levels, topping them off with extra if they’re too low. And we’re told that the benefits of testosterone are HUGE: that we’ll be stronger, sexier, and more energized. So is that true?? And if you do go for a testosterone bump, do you need to worry about possible side effects, like ’roid rage, infertility and other risks?

Collagen peptides!! Can they make you look younger and be healthier? It feels like everyone wants to be bursting with collagen, and apparently the way to do it is by scooping up that white powder of collagen peptides and guzzling it down. Do that, and — according to the wellfluencers — not only will your skin be as bouncy as a baby's bottom, but you'll also be stronger and you'll heal from injuries faster. But of course, not everyone is on the collagen train. There are the collagen haters, who say that eating collagen is a load of baloney. So who's right? To find out, we talk to dietetics Professor Clare Collins, dermatologist Dr. Natalia Spierings, exercise physiologists Professor Luc van Loon and Professor Keith Baar, neutromuscular physiologist Dr. Robert Erskine, as well as sports performance consultant Dr. Dana Lis.    Find our transcript here: https://tinyurl.com/ScienceVsCollagen In this episode, we cover: (00:00) Collagen peptides are EVERYWHERE (02:52) Why is collagen important?

Our brains go completely WILD when we go through our teenage years. It’s a time where it feels like every disagreement with our parents turns into World War III, and every idea that could get us killed sounds like the most fun we could ever have. In this episode, we get into the science of what the brain is doing during the teenage years with clinical psychologist Dr. Lisa Damour. Lisa co-wrote the college textbook “Abnormal Psychology” and was a consultant on Disney's “Inside Out 2.” She takes us deep into the developing brain to explain what makes teens tick. Plus, we talk about mental health, how boys and girls are struggling in different ways, and tips for anyone who has big feelings.   Find our transcript here: https://tinyurl.com/ScienceVsTeenBrain Check out Lisa Damour’s podcast, Ask Lisa: The Psychology of Raising Tweens & Teens, here: https://open.spotify.com/show/2GIh790via4L7oGAJ2mz1b  In this episode, we cover: (00:00) Meet Lisa Damour (05:33) The teenage brain (11:20) Big feelings, what they mean, and how to respond  (19:56) The teenage brain and abstract thinking (22:34) Teenagers and risk-taking (29:18) How long does adolescence really last??  (33:47) The different kinds of popularity (41:58) Should we be worried about kids these days?

Stress! We’re all feeling it. And besides just feeling crappy, we’re also told that stress can wreak havoc on our bodies. The internet has a million solutions: vagus nerve stimulators, deep breaths, or a hot sauna! If that doesn’t work, maybe a cold plunge? But what does the science say about all this — what works to lower our stress? And is it really THAT bad to be stressed out?

Could artificial intelligence really wipe out humanity? Claims that AI poses an existential threat are going gangbusters. AI agents from OpenAI recently hacked into another company, Hugging Face, which has people talking about whether AI can go “rogue.” And some current and former AI company employees are raising the alarm. CEOs have called for a slowdown, and one Anthropic employee just quit, saying that the companies creating this tech are putting us all at risk — and adding that “the people building AI earnestly believe that it could kill us all by the end of the decade.” So — are we really creating a monster? Could AI escape human control and take us all out? If so … how?! And are these scary claims just a distraction from the stuff that AI is already being used for out in the world? We talk to cyber security expert Professor David Parry, philosopher Dr. Nick Bostrom, and scientist Dr. Michael Vermeer to find out.

Bugs are disappearing at alarming rates, scientists are telling us. Bees, butterflies, beetles: all of them have been dropping like flies. And scientists say there are a bunch of reasons to care about this — for example, fewer bugs means less pollination, which means less pasta in your pantry. But recently, some have suggested that all these scientists crying out about the insect apocalypse might just be crying wolf. They say that the math isn’t math-ing and that the insects are doing all right. And this has been bugging us! So we called up Dr. Jessica Ware, an entomologist and a curator at the American Museum of Natural History, to find out what’s going on here. And Jessica also specializes in dragonfly lovemaking, so of course, we had to ask about that too.  Find our transcript here: https://tinyurl.com/SVInsectApocalypse  In this episode, we cover: (00:00) Meet entomologist Dr. Jessica Ware  (03:27) Dragonflies: Origins and sex lives  (08:55) The insect apocalypse: How bad is it?

Protein is everywhere — tons of us are trying to cram more of it into our diets, and it's showing up in our lattes, our snack bars, even our popcorn. But just as we’re getting on board with protein-maxxing, a bunch of headlines have started saying the opposite: that eating LESS protein could actually help you live longer. So what's going on here?? Should we be piling on the protein — or pulling back? And could going too low actually be dangerous?

Sunscreen is supposed to protect us from dangerous stuff like cancer, but all over social media, people are saying that we’ve been getting it all wrong. We’re being told that our sunscreen is full of toxic chemicals, that wearing it could mess with our vitamin D levels — even that sunscreen itself actually increases our risk of skin cancer.

A group of scientists meet a very unusual woman. A key part of her brain isn’t working: the amygdala. This is the part of the brain that we think is responsible for feeling fear. And in fact, this woman does seem pretty fearless. Researchers test her fear response using some very unconventional methods, but she takes everything in stride. Then, finally, they stumble onto the one thing that makes the woman who can’t feel fear absolutely panic. We scare up some science with neuropsychologist Dr. Justin Feinstein.

Headlines have been screaming about a new study suggesting that vaping could cause cancer — and that vaping could be just as dangerous as cigarettes. And if this were true, it would be a HUGE deal. We’ve been hearing for years that vaping is a safer option — and can help you quit ciggies. But the new paper has run up against angry criticisms from other scientists, with some calling the paper "misleading" and "problematic." So what’s going on?? Do scientists still think vaping is safer than cigarettes? How well do vapes actually help people quit smoking? And could Big Tobacco be behind the scenes, clouding the truth about all of this?? We get help sorting it out from Professor Bernard Stewart, Professor Lion Shahab and Professor Becky Freeman.

UPDATE [June 30, 2026]: If we had our time again we would have produced this episode differently. We got carried away with the wildness of the story, from a scientific perspective, and didn't take time to really think about the fact that this is the story of a 15-year-old, who would have been going through a really difficult time. Many of our listeners rightly pointed this out, and we appreciate it." We have changed some of our language in this episode based on the feedback – we replaced all references to woman to teenager or girl, we cut some moments that we viewed as insensitive, and we removed the reference to the girl not being intersex, as some folks with the condition Mayer-Rokitansky-Küster-Hauser syndrome do identify as intersex.  Here’s the story: It's 1988 in Lesotho, and doctors at a hospital see something they thought was impossible. A 15-year-old girl shows up pregnant and in labor, but she's missing something pretty crucial to her delivery: a vagina. So — how did this happen? We speak with Dr. Neel Shah to find out. Find our transcript here: https://tinyurl.com/sciencevsnovagina  In this episode, we cover: (00:00) A small war  (04:42) How do you get pregnant without a vagina?

RFK Jr.’s big report on autism is scheduled to come out this month, and we’re hearing that it might point the finger at Tylenol as a possible cause. And the science on this gets confusing fast. Because some studies do suggest that taking acetaminophen while you’re pregnant could increase your kid’s chance of being autistic or having ADHD. But other research doesn’t find a clear connection — and scientists think there could be a whole other explanation here. So, what’s going on?? We sort it out, with help from epidemiologist Prof. Brian Lee.  Find our transcript here: https://bit.ly/ScienceVsTylenolAutism  In this episode, we cover: (00:00) The fears around acetaminophen and autism (02:18) Could acetaminophen be an endocrine disruptor?

Many of us use artificial intelligence for help with research, work, or creative projects. But some people are getting a LOT more personal with their AI chatbots. We’re hearing stories of people treating their chatbot like a friend, or something more than a friend — with some people saying they’ve even fallen in love with their chatbot. And then there are stories of things taking a scary turn, with people’s mental health spiraling out of control after talking to these bots. So, what should we make of AI companions? Is it risky to spend a lot of time talking to an AI bot? We ask AI researcher Dr. Julian de Freitas and psychiatrist Dr. Keith Sakata.  This episode does mention mental health issues and suicide.

[Video available on Spotify] To start off the new season we’re getting into the science of one of the most controversial and taboo sex topics around. Squirting! For some people, it’s a major sex goal — but for others, it’s a source of major embarrassment. And it turns out that people have been writing or talking about squirting and female ejaculation for CENTURIES. So in this episode, we’re going to find out: what IS squirting (like, what is this fluid??), how common is it, and if you want to start doing it … how can you? We’ll hear from Sex Educator and World Record Holder, Lola Jean. As well as Professor Caroline Pukall, Dr. Nan Wise, Professor Helen O’Connell, and Dr. Samuel Salama.  UPDATE, April 4, 2025: An earlier version of this episode mistakenly said that usually a person cannot pee with an erect penis.

[VIDEO available on Spotify.] Imagine a vagina. You might be thinking of a passive tube, patiently waiting for a penis to shoot out sperm — and you wouldn't be alone. From Aristotle to Darwin, tons of prominent nerds classified males as the active sexual players: They're coercing, manipulating and harassing to reproduce, while the females are passive, coy, chaste. But animal ecologist Dr. Tiana Pirtle is here to give us the real story. Because once scientists started investigating what really goes on in the vaginas of the animal queendom, they realized that — far from being docile tubes — vaginas are packed with their own weaponry, tools and secret chambers. It turns out that both penises and vaginas were allowed to fight in the evolutionary arms race. Pirtle breaks open a box filled with animal vaginas to tell us all about it.   Find our transcript here: https://bit.ly/ScienceVsWhenVaginasAttack In this episode, we cover: (00:00) A Box Full of Vaginas (02:42) The 'Chaste' Female is Born (06:51) The Duck Vagina that Launched a Thousand Ships (11:06) Hyenas and their Pseudo Penises (13:23) Water Striders and their Genital Shields (16:53) Snakes and their Two Vaginas?!  (20:28) Alpacas and their Regal Vaginas (25:31) The Rainbow of Vaginas This episode was produced by Wendy Zukerman with help from Michelle Dang, Rose Rimler, Meryl Horn, and Ekedi Fauster-Keeys.

It’s the 1990s at a medical center in California, and patients are dying. At first, this doesn’t seem strange — it’s a hospital, and deaths happen. But then rumors start to circulate about a particular health care worker: Difficult or needy patients in his care are ending up dead. The cops get involved, but there’s a huge problem: There’s no hard evidence. Until the so-called “Lab of Last Resort” steps in.

For decades, taking the birth control pill to prevent pregnancy was seen as a no-brainer. But lately, people are saying that it’s actually a brain-changer. They say that the pill can affect who you’re attracted to, that it can tank your libido, and that it can make you depressed. Instead, some influencers are telling us to try an amazing, hormone-free method — where all you have to do is listen to your body. So … are they right?? We’re tackling these birth control claims and more, with psychologist Dr. Julia Stern, biologist Madita Zetzsche, neuroscientist Dr. Caitlin Taylor, and ob-gyn Dr. Jasmine Patel.  This episode does mention depression.

This episode asks: Would you alter your body for the chance to compete for a gold medal? You’ll meet runner Christine Mboma and hear about the difficult choice she faces.  Find more episodes of Tested at https://link.chtbl.com/XReiimtO Tested is from CBC, NPR’s Embedded, and Bucket of Eels.

We’re hearing stories of people having amazing, cosmic orgasms. So what buttons are they pressing to do this?? Well, it's just one. The “male G spot,” also called the “P spot,” because that P stands for prostate. Word on the street is that if you touch your prostate in just the right way — BAM — one helluva orgasm. But is that really true? And if you don't have a prostate (ahem, me): are you stuck with your garden variety orgasms? To get to the bottom of this, Science Vs surveyed almost 16,000 people about anal sex and masturbation! We also speak with Dr Dan Dickstein, Dr Tom Gaither and Neuroscientist Dr Nan Wise.

Health care for trans kids has been in the spotlight, with battles over what the science says and tons of U.S. states restricting the care that children can get. And then there’s a new report out of the UK, called the Cass Review, saying that a bunch of the evidence that doctors have been relying on to treat trans kids is “remarkably weak.” So what’s going on here? What is the best health care for trans kids? We sort through the science with Professor Stephen Russell, Dr. Cal Horton, and Dr. Ada Cheung. UPDATE 6/6/24: In a previous version of this episode, we said a study was published this year, when it was actually published last year. The episode has been updated.

The Abortion Pill is now the most common way to have an abortion in the US. Yet what exactly happens when you take these pills is shrouded in mystery. Even many doctors don't know how well they work! Today, we're letting the sun shine on the abortion pill.

To explore all this - and more - we speak to Dr Sara Whitburn, Professor Oskari Heikinheimo, and Professor Ushma Upadhyay.
