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.

Science Vs

Every day we’re all doing a little bit of chemistry: when we bake potatoes, add a little salt to our pasta, or even bake a box cake. And award-winning chef Samin Nosrat just loves to nerd out over all this. She's the author of the best-selling book “Salt, Fat, Acid, Heat” and has a new book out called “Good Things.” Today, Samin joins us to talk all about the science and art of cooking. Plus — why you should NEVER put meatballs on spaghetti.

Video available on Spotify.

Never Put Meatballs on Spaghetti, with Samin Nosrat

The internet is abuzz with accusations that artificial intelligence is using up tons of energy and water. People are even protesting the building of new AI data centers, saying they’ll put a huge strain on local resources. But some AI defenders say that this fear is overblown and that AI isn’t actually that bad for the environment. So who’s right? We talk to science and tech reporters Casey Crownhart and James O’Donnell, and computer scientist Prof. Shaolei Ren. 

UPDATE, 11/13/25: This episode has been updated to note that some AI companies advertise on the show.

AI: Is It Ruining the Environment?

We’ve been told that foods like butter and bacon are bad for us — because they're packed with saturated fats. And top dogs in nutrition say that a better option is vegetable oil, like canola oil. But lots of people, including HHS Secretary Robert F. Kennedy Jr., are saying hold on. They're arguing that saturated fats are actually the way to go. And they're claiming that those vegetable oils, aka “seed oils,” are incredibly dangerous. So — who’s right?? To find out, we speak to author and physician Dr Cate Shanahan, professor of nutrition science Jason Wu, professor of endocrinology David Schade, and Dr David Iggman. [REBROADCAST]

The Full Moon: Is It Messing With Us?

Ever wonder why your dog just loves to sniff your junk? Well, it turns out it’s because other animals perceive the world in wild ways that we’re just beginning to understand.

How to Smell like a Dog, with Ed Yong

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.
