The hows and whys of hair

2019-04-1600:33:32

The hair on our heads is on our minds. We have fun with follicles and learn about how they make hair. Our experts help us decipher what makes hair black or brown, blonde or red, and even why it turns gray. From eye lashes to ear and nose hair, this episode has it all. Why do humans have hair and not fur? Why is there hair on the top of our heads? How does hair grow? How does hair become curly or straight? Plus: A brand new Moment of Um answers the question: "Why does my dad get fuzz in his belly button?"

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. We'll also learn why the predictability of messages and alerts on smartphones makes them extra hard to put down. Plus, we’ll get a few tips from Catherine Price, the author of How to Break Up With Your Phone. Price has more resources for screen time habits at https://phonebreakup.com/. And! A new moment of Um: why are bruises blue, and how do we get them?

Most plants get the energy and nutrients they need from water, sunlight, air and soil. But carnivorous plants get key nutrients from a different source: bugs. We’ll find out how they do it and talk about the mystery of how venus fly traps snap shut. Plus: Two gardeners – one very experienced and one just starting out – offer their tips for growing venus fly traps.So that’s plants, but what about animals? Carnivores are animals that only eat other animals – so how do they get the vitamins, minerals and fiber that we humans get from eating plants? We take a trip to a salad bar with some animal pals to find out.

Black holes happen when you have a super huge, mega-giant amount of stuff --- crammed into a super-tiny, infinitely-small amount of space. AND THEY ARE SUPER COOL! In this episode, we learn all about what black holes are and how we found out they were real. We talk to a black hole hunter who has discovered supermassive black holes. And we find out what a wormhole is and why it might really, be really, really hard to ever find one -- or travel through it. Plus: The Moment of Um answers the question: "Why do goat pupils look like slits?"

Ants and spiders are able to defy gravity -- but how do they do it? We'll learn about how awesome their feet are and how one predator takes advantage of these powers.

Oxygen is quite the savvy traveler. We explore how this gas travels all around the world and ends up pretty much everywhere for us to breathe. Plus we'll look at how plants and others make the stuff. And we learn how oxygen ended up on Earth in the first place (hint: it involves super space explosions!). We'll make friends with some molecules, hear about a tiny fart that changed the world and guess an all new mystery sound.
