In our final look at metal, we explore how metal wires changed the world. Once humans figured out how to send little blasts of electricity through metal, we quickly developed lots of uses for this. One was a new way of communicating called the telegraph. Join Molly and co-host Ava as they team up with Dylan Thuras, co-founder of Atlas Obscura to learn how people laid hundreds of miles of wire in hopes of sending messages across oceans. Plus, the new Brains On Headquarters is having an opening ceremony, and there’s a brand new Mystery Sound to guess!

Millions of kids and adults across the world have ADHD, which stands for Attention-Deficit Hyperactivity Disorder. ADHD doesn’t affect everyone in the same way, though.

We listen to music with our ears – and that amazing electric meatball between our ears: our brain! But why do our brains find some music scary? We’re born with some fears baked into our brains, because our ancestors thought they were scary too! That’s why sudden loud noises startle us sometimes. But there’s another reason certain sounds freak us out – we’ve been taught to find them scary. We’ll hear how composer Heather McIntosh uses these fears to write scary film scores, and we’ll explore some of the ways scary sounds make their way into music with pianist and musical magician, Jae Kyo Han.

That’s when you take turns trying to come up with something that nobody else can imagine. We’ll also meet some of our listeners’ imaginary friends and learn why some people have these companions.

You can find micro-animals just about everywhere. They’re on your face and in your hair. They’re in puddles and in soil. One of the most famous of these microscopic creatures is the tardigrade. This episode zooms in on these adorable little animals, also known as moss piglets and water bears. The biggest tardigrade is about the size of the tip of a sharpened pencil, but most are smaller. More like the width of a hair. They’re kinda like a squishy pillow with eight legs, four on each side, with finger-like little claws at the end of each leg. And a round, snout-like opening on its face. Jasmine Nirody tells us what she’s learned about these cuties through her research. She’s watched hundreds of hours of tardigrade videos. Way better than YouTube, right? We’ll also hear about where you can find tardigrades, how they live and why we’ve sent them to space. Don’t forget to check out the brand new Mystery Sound too.

There are many different types of snow. From the fluffy to the slushy, this slippery frozen stuff comes in all different shapes and sizes. From a distance, snowflakes may all look the same, but they are not. In fact, there are lots of different shapes of snowflakes — not just those classic shapes you might try to replicate with paper cut-outs. In this episode, Dr. Ken Libbrecht answers all of our snowflake questions: How are snowflakes made? Why are they different shapes? How is it that they’re all unique? And how does a scientist who lives in southern California study snow? And, he also lets us in on his brush with a couple Arendelle princesses. Plus our pal Ruby Guthrie pays her local ski slope to visit a snow-making machine called “Kevin.” And of course, there’s a new Mystery Sound to warm your ears.

Today we’re sharing an episode with you from our friends at Million Bazillion, the podcast that answers the questions kids have about money. They help dollars make more sense and they’re back for a whole new season! In today’s episode, hosts Jed and Bridget answer a question from two curious listeners who want to know why we pay taxes. In answering the question, they come across the legendary Robin Hood, known for his hatred of taxes. Back in his day, tax-collecting sheriffs forced people to pay money to a king, who decided how those taxes were spent. These days our tax system works a bit differently. We get to vote for people who’ll spend that money on things we care about — like schools and libraries, health care for elderly people, police, parks, sewers and so on. With the help of a rambling troubadour and a tax policy expert, Jed and Bridget teach Robin Hood that the way tax dollars are spent today reflects what we prioritize as a society. Plus, we’ll ask random kids some not-so-random questions. Million Bazillion is a collaboration between Brains On and Marketplace. It’s hosted by Jed Kim and Bridget Bodnar.

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.

We’ve all played the “what does that cloud look like” game. Maybe you saw a bunny… or an airplane… or a unicorn. What if that same cloud could also be seen by someone in a far off continent? That’s what a listener in Minnesota wondered. He wanted to know if the same cloud he saw in a park near his house could also be seen in Africa. We talk to Deanna Hence, one of our favorite weather experts, and she tells us about how clouds travel. We also dust off the Zoom Ray to learn about what is inside of a cloud. And have you ever noticed the similarities between cloud types, like cumulonimbus, and magic spells from Harry Potter ? Well, we have, and we made a game out of it!

20 years ago, we pictured dinosaurs as green, scaly animals. But times have changed! Now, we know some dinosaurs had feathers. And who knows — maybe some even had stripes. This episode looks at how we figure out what color dinosaurs might’ve been. We talk to Jingmai O’Connor, who studies fossil reptiles, about finding color pigment in fossils. And paleoartist Emily Willoughby talks to a “museum” about how her dino-depictions have changed over the years. Our co-host, Elyana, also brought us this important question: If dinosaurs evolved from birds and birds don’t fart, did dinosaurs fart? Wha-wha-what!?! Look no further than this episode for an extensive investigation. Remember to keep your ears open for the brand new Mystery Sound. And break out your kilns, because today’s Moment of Um answers this question: How do you make clay for pottery?

Since the world first learned about this new coronavirus at the end of 2019, we’ve been watching science happen in real time. Scientists all over the world are studying this virus and learning how to protect us from it. As they learn new things, we learn new things too. One thing they’ve learned is how this virus spreads. The primary culprit is droplets from our noses and mouths. That’s why masking up is so important to protect our communities. We’ve also been hearing from a lot of listeners wanting to know about the future: when will the vaccine be ready? what will it be like at school? when will things go back to normal? We're going to do our best to answer some of these questions in our next coronavirus episode. But they don’t have concrete answers right now. Right now, trying to look a month, or a year into the future is hard. We call this feeling of not knowing what will happen -- uncertainty. And it’s hard to deal with. Our brains likes being able to predict what’s going to happen because it makes us feel safe. When we feel unsafe, that’s when anxiety kicks in. One way to deal with this anxiety is to focus on the present -- what’s happening right now. It’s also important to let yourself feel your feelings and know you’re not alone in them. It’s normal right now to feel frustrated, or angry, or sad, or all of them at the same time. But also try to think about the moments you have that are fun, and the times you feel contentment and happiness. If you’re having trouble staying focused on the present there are some tricks you can try: Look around you and make a list in your head of everything you see that is green. Try to think of all the character’s names in your favorite book or tv show Take deep breaths -- inhale for four counts, hold that breath for four, and then exhale for four Distract yourself by going outside, or watching a movie or reading a book. If you’re still having trouble keeping your mind off the “what ifs” it’s great to talk to your parents or another adult you trust. There are always people who want to help you. If you need help and aren’t sure who to talk to, you can call 800 273-8255. It's a free phone call, and people are there all the time, ready to listen and help.

A lot of us are angry right now, with good reason. We’re seeing people treated unfairly because of racism -- that’s when people don’t like someone’s race or the color of their skin.

Plus, our Moment of Um tackles the question, “What happens when lightning strikes water?” If you want to talk to your kids about race but don’t know where to start, we suggest reading this article (https://bit.ly/3eEss5k) by pediatricians Dr. Jacqueline Dougé, & Dr. Ashaunta Anderson or Talking to Kids About Race by Heather Greenwood Davis ( https://on.natgeo.com/306a2Xe ).

We'll talk about some ways to help handle sad feelings (doctor-approved pet cuddles, anyone?).
