Bacteria are among the simplest forms of life on Earth. Each cell is identical to the one next to it, sharing the same DNA. So why do they all act so differently? Turns out, there’s a “cookbook” inside each teeny tiny bacteria cell, and every single bacteria has different ideas about the recipes it wants to make. Mary Dunlop is a biological engineer who’s a creative cook both in the kitchen and the lab - and she’s cooking up her own experiment of science discovery. Watch Mary’s “cell movie” on the blog post on our website, sciencepodcastforkids.com. It’s really cool to see! You can learn more about synthetic biology in our interview with Mary, available for Patrons who pledge at the $1/level or higher, on patreon.com/tumblepodcast.

Everybody poops. But why? To find out, science writer Mary Roach takes us on a journey into the alimentary canal - that's the tube that runs from our mouth to our rectum. Along the way, we learn about pooping in space, and how someone else's poop might one day save your life! We love all science here at Tumble, but poop science holds a special place in our hearts. We hope you enjoy this extended cut of “The Secret Life of Poop” where we learn more about why poop is not only funny, but important to our health.

The Great Pacific Garbage Patch is a vast, swirling soup of trash, twice the size of Texas. Can we ever clean it up? That’s what 8 year old Ila wants to know. She lives in Hawaii and likes to pick up trash whenever she goes to the beach. She lives closer to the garbage patch than most of us. Finding the answer to her question, led us to create one of our favorite episodes of Tumble. We talk to Jenni Brandon about how she learned about the garbage patch, what it is like to be there, and what can be done about it. We’re on summer baby break, but Season 5 is coming in Fall 2019! We rely on listener support to keep making the show. Pledge on Patreon for bonus interview episodes, birthday shoutouts, and more!

This is the last episode of Season 4, but stay tuned for our special summer lineup! We’ll be back for Season 5 in fall 2019. Why are butterflies so colorful? That’s what Zed, from The Petit Punk Podcast, wants to know. So we went on a family podcast field trip to the Museum of Natural History in Paris, where we met Zed, his mom Dana, and a butterfly scientist named Marianne Elias. Come with us as we visit the museum’s private “butterfly library,” and find out why some butterflies are toxic! Plus, we’ll learn why Marianne climbs trees when she’s not in her office.

Is there a hard edge to the solar system? This question led to a big, breakthrough discovery that changed the way we picture the solar system - and every other solar system in the universe. The Kuiper Belt is a gigantic field of small, icy objects beyond Neptune, “planet scraps” left over from the formation of the planets. For many, many years, no one believed it might exist. Until astronomers Jane Luu and David Jewitt decided to see what was out there. Jane Luu tells the story of how she helped discover the Kuiper Belt. We have an exciting announcement!
