Do you love fossils, adventure, and spending time in small spaces? If so, you could become an underground astronaut! Marina Elliot, Becca Peixotto, and Kenni Molopyane found this unusual job description through a Facebook ad, and landed deep inside a cave that few people can access. The team of archeologists talked to Tumble in the middle of excavating Homo Naledi, one of the biggest recent discoveries on the human family tree. Find out how they squeeze through a 7 inch gap on their daily commute, and how their work could change the way we understand early human history. 

Hear more from inside the cave with Marina, Becca, and Kenni when you pledge $1/month on <a href="http://patreon.com/tumblepodcast" rel="nofollow" target="_blank">Patreon</a>! Support Tumble and get bonus interview episodes of new episodes. 

Find out more about Homo Naledi, and how you can explore the cave in virtual reality, with resources on our blog.

The Cave of the Underground Astronauts

How do species get their scientific names? To find out, Lindsay and Marshall take a field trip behind the scenes at the Smithsonian National Museum of Natural History. That’s where we meet Chris Mah, a sea star scientist who has discovered and named over 50 new species! (You might remember him from “The Surprising Story of Sea Stars’ Sticky Feet.”) Chris shows us next season’s hottest new sea stars, shows off his amazing toy collection, and shares the secrets behind his super naming super powers. 

What would you name a new species, and why? Tell us at <a href="mailto:tumblepodcast@gmail.com" rel="nofollow" target="_blank">tumblepodcast@gmail.com</a>. 

See Marshall’s photos from our trip, including Chris’ amazing office and the giant not-so-giant sea star he shows us in the episode. It’s on our blog at sciencepodcastforkids.com.

The Superpower of the Secret Names

Who would win in a competition, a hamster or bacteria? Place your bets, because we’re going to tell the story of this epic science showdown. Danielle Tullman-Ercek is a synthetic biologist trying to find a better way to make life-saving medicine. To do it, she’s engineering a bacteria cell to compete with a medicine-making hamster cell. Listen to find out what if Danielle and her bacteria have what it takes to win. What’s a hamster cell doing making medicine, anyway?!

If you engineered your own bacteria, what would it make and why? Draw a picture and email it to us at <a href="mailto:tumblepodcast@gmail.com" rel="nofollow" target="_blank">tumblepodcast@gmail.com</a>! To learn more about synthetic biology, check out our blog.

Hamster Versus Bacteria

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! We’ve partnered with Castbox to launch Tumble Premium, a channel on the Castbox app featuring ad-free episodes and all our bonus interview episodes too! It’s $1.35/month through the app, or $16/year. You’ll be helping support the show while listening on a great podcast app! 

Don’t worry, we’ve still got the same great audio extras available on Patreon, too. This week, we have more from our interview with Jane Luu on ‘Oumuamua, the mysterious, weirdly shaped, potentially alien (yes, THAT kind of alien!) space object. Pledge at patreon.com/tumblepodcast.

The Search at Edge of the Solar System

How do cheetahs get their super speed? We talk to a cheetah scientist to find out why a spotted cat is the fastest animal on Earth. Cheetahs are literally built for speed! Anne Hilborn spent months scoping out cheetahs on the hunt in the grasslands of the Serengeti. We’ll discover how cheetahs’ incredible speed is linked to their survival - and what they do when being fast isn’t enough. ****

On our special bonus interview episode - available to our Patreon &amp; Castbox supporters - Anne shares the amazing story of how being photographed while dropping cheetah poop on herself became both her most embarrassing and her proudest moment. Photos on the blog!

The Secret to Cheetahs’ Super Speed

Meet Ana Humphrey. She hasn’t graduated from high school yet, but she’s already discovered 560 places outside our solar system where we could find hidden planets. Ana won the 2019 Regeneron Science Talent Search with her project that used a mathematical model to pinpoint locations for exoplanet search parties. But Ana’s story is more than a successful science fair project. Find out how Ana’s love for science, math, and making a difference in her community helped her become a high school astronomer!

You can hear our full interview with Ana on our Patreon and Castbox Premium channel. She has a great perspective to share on how science and math can be used to understand the world - and more on how her early concern for the environment helped lead her into space.

The Tale of the High School Astronomer

Why do seals have whiskers? Listener Karah’s question dives into the wonderful world of whisker science. Robyn Grant, a self-described “whisker biologist” shares her discoveries of how whiskers work, from training a friendly seal named Moe to making slow-mo movies of super speedy “whisking.” (You will find no cuter field of research… but if you do, tell us about it!) Listen to learn about humans’ hidden whisker muscles and find out to rank whiskers like the pros!

Why are hurricanes so powerful? Every year, monster storms develop in the Atlantic Ocean from June until November. It seems like they come out of nowhere. But scientists are working to predict them months, years, and even decades before they start. We’ll discover what makes hurricanes so destructive, and why they might become even more intense in the future. Might it have something to do with gnomes that ride on hamsters? Listen and find out!
