You dream every night, even if you don't remember them. But why? We'll hop on a wild ride to go inside the brain and see which parts help create these often fantastical images and storylines. We'll also learn how to take control of our dreams and how they make us more creative. Plus: a new mystery sound and a Moment of Um answers the question "How do octopuses make ink?"

Can people actually read minds? Can we move objects with our brains like in the movies? We're exploring the history of shady psychics, sketchy seances, and secret superpower studies. Plus, hear from a scientist who is helping people regain the ability to pick up and move objects through the combined power of their brains and a special computer!

Come take a fictional tour of the Night Owl Sanctuary, where Nolan the know-it-owl fills us in on cool owl facts.

The ExPLORERR was built to go everywhere. That’s why this vehicle’s full name is: the Extremely Practical Land and Ocean Rover Exploring Remote Realms. And guess what? It has a recording studio built on-board! Good thing, because this episode was recorded while traveling up, up, up a mountain!

What route would you take to walk around the world?

Marshmallows, lollipops, gummi bears -- we want them all! But we’ve all heard that eating a lot of sugar isn’t that healthy for us. So what’s the deal? Why do we like sugar so much in the first place? We’ll find out why our bodies evolved to seek out sweet things, and how clever humans invented a way to make food even sweeter. And we’ll get to the bottom of a confectionary conundrum from our co-host Zoe: are sugar rushes a real thing? Plus: Sanden cooks up some very sweet schemes and we have a new mystery sound for you to guess!

Oh wow, Moment of Um has a podcast!

We’re heading to space, and dropping a feather in a few different places to see what happens!

We’re heading to a squirrel-themed adventure course and practicing a few of the skills they use to survive: gathering nuts, traveling in trees, and speaking like a squirrel.

Explore the ins and outs of breathing

From wigglers to lost teeth traditions, we're looking at all things chompers. Chew on this!

Adults around the world are getting vaccinated against the coronavirus, and now, in a handful of countries (including the U.S.) kids over 12 can get vaccinated too.

We hear from a 13-year-old who participated in a clinical trial for a vaccine and get tips for how to navigate the world when only some people in your family are able to be vaccinated. Plus, Kara and Gilly share expert advice on how to handle big feelings as the world starts to open back up.

We treat dogs like they're part of the family. But do they know they are a different species, or do they think they're just short, four-legged people?

In this episode, canine cognition researcher Alexandra Horowitz helps us puzzle out this question. We’ll also find out what happens (or doesn’t) when a dog looks in the mirror. Dogs are always dozing, and we’ll check in to see if they are dreaming too. And, we take a quick trip around the world in the language of barks.

All that, plus a brand new Mystery Sound and moon-filled Moment of Um.

Can the same cloud you see travel halfway across the world?

Screens are everywhere these days! We’re taking a look at why smartphones are so addictive, and how our devices affect us. Our co-hosts took on a bold challenge for this episode: they went a week without phones or tablets. We’ll hear how their experiment went, then Sanden will fill us in on the brain chemical that trains us to love our screens.
