The heroes we need to defeat the coronavirus
Eighteen months into our fight with this coronavirus, it may feel frustrating that we're still in this battle, but there are many reasons to feel hopeful. One reason is that we know a lot about this virus now and have plenty of tools to fight it. We meet the superheroes prepared to help us defeat the coronavirus: Sgt. Socially Distanced, the Masked Mentor, the Testmaster and the Vaxinator! Plus: Gilly, one half of the hit podcast Going Viral with Kara and Gilly, and a special guest explain what a virus variant is and how the delta variant is different from the original coronavirus. Also, journalist Sarah Zhang helps us understand how the pandemic could end.
All that, plus a new mystery sound and a Moment of Um that answers the question "How do skunks spray their stink?"

Take a deep breath: How does breathing work?
Breathing is a really cool thing. We breathe automatically without thinking about it, but we can also control our breath and play with it. We'll learn how our lungs work and why our bodies need this air in the first place. We'll also hear from a singer and a free diver about how they've trained their breath to do remarkable things -- and how you can too! And we'll talk to a doctor about how deep breathing can help you feel less stressed and she'll teach us an exercise you can do whenever anxiety starts to creep up. Plus: Our Moment of Um answers the question: what is the smallest unit of measurement?

Why do we lose teeth?
Today we’re looking at a phenomenon that happens to all of us: losing our baby teeth and getting new ones! So how do our teeth grow in and what makes them fall out? Naturally, a group of wandering teeth helps us explain. We'll also find out why we have two sets of teeth in the first place. A chatty tooth travel agent will introduce us to all the different ways to send our baby teeth off in style and we'll play a game that will test your knowledge of animal teeth. Plus, the Moment of Um answers the question "Why do bees make a buzzing sound?"

What causes wildfires?
A fire can be super useful or cozy or even magical. But it can also be dangerous -- and in the case of wildfires, if they burn long and hot enough, they can destroy ecosystems and send lots of harmful smoke into the air.
In this episode, we're going to find out why wildfires are getting bigger and why wildfire season is lasting longer now. We'll learn how the tribes who've lived in what is now called Northern California managed the forests and kept fire in check for thousands of years, and how those practices are being used today.
We'll hear from a friendly house about how to stay safe from smoke inside and find out how firefighters work to contain fires once they've started.

Million Bazillion answers your questions about money
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.

Vaccines for kids and silver linings: Our second COVID summer
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.
And a new Moment of Um answers the question: What are eye boogers?

Do dogs know they're dogs?
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 a Moment of Um that answers the question: “Why does the moon follow us?”

Our 200th episode is SUN-sational!
There’s no better way to celebrate our 200th episode than with our own shining star: the sun! In this episode we speak with Dr. Nicola Fox, who leads a team of NASA scientists that sent a probe to collect data and zoom by the sun. We also hear some great listener suggestions on what new planet could be added to our solar system. We even get a chance to check in with The Sun and her weekly broadcast, That’s Hot.
Our 200th episode wouldn’t be complete without a visit from some of our favorite pals: Bob, Gungador, Harvey and Elevator! Of course there’s a new Mystery Sound too. And the Moment of Um comes just in time for mosquito season, because it answers the question: Why do we itch?
Thank you so much for helping us make 200 episodes! We could never have done it without your questions and encouragement, and we can’t wait to make 200 more!

How far can a cloud travel?
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!

How do computers store so much info in such a tiny space?
If you translate “Hello! How are you?” to binary code, it looks like this: 01001000 01100101 01101100 01101100 01101111 00100001 00100000 01001000 01101111 01110111 00100000 01100001 01110010 01100101 00100000 01111001 01101111 01110101 00111111
This episode takes a look at how computers can do so much with such tiny parts. But computers weren't always small -- so we take a look at where computers came from. We visit Ada Lovelace, whose love of math and weaving paved the way for modern-day computers. And we hear about the material that let computers shrink from the size of a room to something that fits in our pockets. There’s also a visit from a yak and a ram, but you’re just going to have to listen to find out why.
All that plus a new Mystery Sound and Moment of Um that answers the question: what is the flavor of root beer?

Will we ever get to rewind time, or fast forward through it? Sanden stops by to tell us all about how time works. He also has a couple ideas about how we might make time travel a reality! But one tricky thing about time travel is that it’s full of paradoxes — so we look into those, too. And science fiction expert Lisa Yaszek swings by to tell us just how long humans have been thinking about time travel (hint: a really long time).
Listen closely for the mystery sound, and the moment of um: how do clothes get dirty even though you can’t see it?

Dino Edition: How do we know what dinosaurs looked like?
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?
There’s so much dino-tastic information that we decided to make a second dinosaur episode. So if you haven’t had enough (and who has?), make sure to check out next week’s show about what dinosaurs might have sounded like.
