There are a lot of fads, blogs and strong opinions, but then there’s SCIENCE. Science Vs is the show from Spotify Studios that finds out what’s fact, what’s not, and what’s somewhere in between. We do the hard work of sifting through all the science so you don't have to and cover everything from 5G and ADHD, to Fluoride and Fasting Diets.

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. So, what can the science tell us here? Should we toss our SPF-filled creams and sprays in the bin?? And could the answer here be different depending on your skin tone? We talk to researchers Dr. Brandon Adler, Prof. Rachel Neale, and Dr. Adewole Adamson to find out.

Sunscreen: Could It Be Toxic??

Hank Green is one of the most beloved science creators on the interwebs. He’s been making videos for almost 20 years, spanning LOTS of eras of the Internet, from YouTube prank videos to TikTok dance challenges to AI slop. In this episode, Wendy sits down with Hank to talk about this wild ride. They reminisce about his path to YouTube stardom, and they’ll pull back the curtain on social media algorithms — how they’ve changed, and the sneaky ways they draw us in. And while Hank has been publicly fighting off internet trolls, he’s also been dealing with his own personal battle with cancer. He takes us through what’s changed for him since he got diagnosed, and the science he learned about pee and chemotherapy along the way.

Weight Loss: Why Won't It Stick?

Will you hit play on this episode?? It feels like that decision is totally within your control — but what if it’s not? What if free will is just an illusion?

But do we really have science receipts for that? We find out by talking to neuroscientist Prof. John-Dylan Haynes and theoretical physicist Prof. Sean Carroll.

Caffeine: How Much Is Too Much?

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.

Peptides are huge right now. Influencers are telling us they can work wonders for all sorts of stuff. Struggling with an annoying injury that won't heal?? Belly fat that's pissing you off? Low energy? Gut issues?? There’s a peptide out there for you. People are buying peptides off the internet and injecting themselves with them, saying it's life changing. But away from the internet hype, there is actually a potential revolution happening in medicine around peptides. So we’re finding out what scientists are excited about here, and we look deeply at the science behind two massive peptides: BPC-157 and MOTS-c. And we’ll also look at the risks: Could peptides give you cancer? On this episode we talk to Dr. Hassy Cohen, Dr. Keith Baar, Dr. Dhruv Khullar and Dr. Cory Mayfield to get to the bottom of this.
