How Do Toilets Work? [ENCORE]
When you have to go, where does it go? That’s what our listener Ellie wants to know. Prepare for potty humor and science as we hear from civil engineer and toilet expert Francis de los Reyes! Who invented the toilet? And what’s “The Great Stink?” We’ll be plunging into the past, present, and future of flushing to discover how toilets don’t just save us from stinky smells - they save lives.

Saving Animals with Rae Wynn-Grant
Have you listened to our most recent episode, "What If There Were No Animals"? In the episode, we met Rae Wynn-Grant, an ecologist who told us what Earth would be like if there were no animals. In today’s episode, Elliot learns more about how exactly experts and communities go about making a world that’s better for animals. Tune in to hear amazing stories of conservation and how you can help save endangered species.

What If There Were No Animals?
What would the world be like without animals? Rae Wynn Grant - ecologist, podcaster, and bear cub cuddler - gives us a picture of what would happen if animals disappeared, and explains how we can stop it from happening. We’ll find out how the Endangered Species Act has worked for over 50 years to save endangered species, and how we can make it even better for the next generation. Thanks to Elliana, as well as Hadley and Roman for their question!
This episode is part of the Kids Podcast Party! Tumble and other kids podcasters are making episodes to commemorate the 50th anniversary of the Endangered Species Act. Want to hear more? Check out Smash Boom Best, and their episode about Capybaras vs. Komodo Dragons.

Controlling Parasites with Sebastian Lourido
Have you listened to our most recent episode, “The Mind Control Cat Parasite"? In the episode, we met Sebastian Lourido, a biologist who studies toxoplasma gondii. This parasite can manipulate the behavior of mice, making them lose their fear of cats! In today's episode, Elliot learns more about Sebastian's journey into the lab and how he applies his creativity to the crucial battle against parasites.

The Mind Control Cat Parasite
It’s a Halloween episode! “There’s a scary secret lurking in the kitty litter…” We’re making a horror movie about a common cat parasite - that can control minds! Toxoplasma gondii makes mice lose their fear of cats, in a plot to take over the world! Biologist Sebastian Lourido helps us tell the true tale of toxoplasma’s quest for cat domination, and what scientists are doing to stop the parasite in its banana-shaped tracks.
The World of Blindness with Andrew Leland
Have you listened to our most recent episode, “How Do We Read?" In the episode, we met Andrew Leland, a writer who told us about his experiences with braille. In today's episode, Elliot AND Marshall learn more about Andrew's blindness and the wonderful world of accessibility. Tune in to hear about Andrew's inspiring fight to learn braille!

How Do We Read?
How does reading work in the brain? It’s a question that has fascinated scientists for years. Could braille - the system of raised dots that blind and low vision people use to read - be the key to understanding how it works? We talk to writer Andrew Leland (“The Country of the Blind”) and neuroscientist Simon Fischer-Baum to learn about the invention of braille, and how it could be the key to learning how reading works - for everyone. And we might just solve a bedtime reading mystery along the way.
Learn more about braille on the bonus interview episode on our Patreon, at patreon.com/tumblepodcast.
We have more free resources about braille and the science of reading available on the blog on our website, sciencepodcastforkids.com

The World of Fungi with Lee Davies
Have you listened to our most recent episode, “The Science of Fungi”? In the episode, we met Lee Davies, collection manager of the Fungarium in Kew Gardens London. Lee took us into the world of fungi science and today, Elliot is looking deeper into mycology. Who was the first mycologist at Kew and what is the science like today? Tune in to hear the wonderful world of Lee's work.

The Science of Fungi
Do fungi breathe? That’s what listener Alice wants to know - and we’ll find out in our punniest episode yet! We visit the Fungarium - the largest and oldest collection of fungi in the world with curator Lee Davies, who describes himself as a “librarian” of mushrooms. We’ll explore how fungi live and die, and why there’s so many species left to discover. Watch out for the zombie fungi! And beware, Lindsay and Marshall don’t hold back on the “fun guy” puns!

Dog Smarts and Training with Zachary Silver
Have you listened to our most recent episode, "What Do Dogs Think"? In the episode, we met Zachary Silver, a canine cognition researcher who investigates just how smart dogs are. Today, Elliot is learning more about the questions Zachary and his lab ask when it comes to dog smarts and dog training! Tune in to hear about what inspires Zachary!

What Do Dogs Think?
“Do dogs think and feel the way we do?” We all know dogs can’t talk. That’s why scientists have to come up with creative ways of asking our canine companions what’s going on in their minds. We’ll find out why dog cognition scientist Zachary Silver put on a play for dogs - which inspired us to create Tumble’s very first dog radio theater production! Just call us “The Tumble Dog Players.” It will all make sense by the end of the episode.
This is the final episode of Tumble’s 8th season! But stay subscribed for some special treats over the summer.

Accessible Technology with Yuma Antoine Decaux
Have you listened to our most recent episode, "Hearing the Stars"? In the episode, we met Yuma Antoine Decaux, a computer engineer who’s developing accessible technology like Astreos - an astronomy app. Today, Elliot is investigating this accessibility and why it's so awesome. Tune in to learn how Yuma overcame obstacles and used creativity along the way!

Hearing the Stars
Can we hear and touch the stars, if we can’t see them? Yuma Decaux is trying to put the night sky into everyone’s hands, through technology and engineering. Find out how stargazing captured Yuma’s imagination when he was six, and how losing his sight inspired him to explore the cosmos in a whole new way - making astronomy accessible to everyone.
Astreos, Yuma’s app, is currently in Beta. That means that when you try it out, you can give Yuma feedback on how to make it better! Download it on iOs here: https://astreos.space/

Are Human Brains Special? - with Suzana Herculano-Houzel
Have you listened to our most recent episode, "Was T-Rex Smart?" In the episode, we met Dr. Suzana Herculano-Houzel, a neuroscientist who told us how brains have developed and, well, how smartness began! We learned about T-Rex brains in the main episode, but today, Elliot is wondering about human brains. Are they really that exceptional? Join us as Suzana shows us the secrets of brain science!

Was T-Rex Smart?
When did smartness begin? We’ll find out how a neuroscientist blends up brains, and cracks the case of the Tyrannosaurus Rex smarts! Suzana Herculano-Houzel helps us answer listener Penny’s question by explaining how “smartness” might not mean what you think - and how all animals have shown off their intelligence over time.

Henrietta Leavitt's Impact with Karen Masters
Have you listened to our most recent episode, "How Big Is The Universe?" In the episode, we met Karen Masters, an astronomer who told the story of Henrietta Leavitt. Henrietta made a huge impact on astronomy, so in today's interview extra, Elliot explores her influence on today's science world with Karen.
Click here to access Galaxy Zoo!

How Big is the Universe?
How big is the universe? And how do we know? It's a question that puzzled astronomers for centuries. They had no way to measure distance in space - until Henrietta Leavitt showed them how. Henrietta Leavitt was a "computer" in the 19th century, before there were computers, and she made an incredible discovery that would help change the way people thought about the universe - forever. Modern-day astronomer Karen Masters helps us tell her remarkable story.
If you like this episode, you'll love our free audio course, "Cataloging the Universe" where you'll learn much more about how Henrietta Leavitt's discovery made a big difference in astronomy - plus, you'll become a skywatcher yourself!

We're working on a special project that we'll announce in our next episode! Enjoy one of our favorite episodes while we make it ready for you.
Why and how do cats purr? That’s what Reid wants to know. It sounds like a simple question, but it leads us to a deep challenge: Can we ever understand cats? To find out, we launch a full-scale cat purr investigation. You’ll hear from a puzzled veterinarian, a scientist who studied her cat’s annoying purr, and the author of purring.org, the premier cat purr research website. It’s a purr-fect episode for everyone who’s curious about cats.
