Ancient Egyptians did lots of amazing things, from building pyramids to inventing a form of writing called hieroglyphics. They also mummified important people after they died. In this episode, we’ll explain how that process was done and why. We’ll also meet a museum curator who thinks it might be time to rethink how we study mummified people.

Plus, we’ll find out why so many things from ancient Egypt are still around, meet a biker club that loves respecting other cultures and hear an all new Mystery Sound.

Do insects see the world in slow motion? Do animals see the same rainbow we do? How do eagles see so far away?

Our listeners have a lot of questions about the way animals see the world, and this episode tackles lots of them. We'll visit a lab where scientists are observing predatory insects to find out how their brains work, we'll drop in on the Eyes Open Wider support group for animals, and give you a catchy melody that will help you remember the electromagnetic spectrum -- that's all the light that's both visible and invisible to us.

The full moon is bright, beautiful, and reappears in the sky like clockwork. Many cultures use the full moon to mark the passing of time and organize calendars around the moon’s cycle. So why does the full moon also have a reputation for causing mischief and mayhem? In this episode, we’ll learn where some of these beliefs come from and investigate whether the full moon actually does affect humans and our behavior. We’ll also hear about folklore tied to the full moon and examine how the moon’s phases work. All that plus a brand new mystery sound!

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. Plus an extra mysterious mystery sound!

Today’s episode is all about one of the most dynamite dinosaurs, the Brontosaurus! This long-necked icon has been featured in books, cartoons, movies, and even logos. But did the Brontosaurus really exist in the first place? We’ll dig into that question and uncover the history of Brontosaurus with science writer and bronto-enthusiast Riley Black. We’ll also learn about taxonomy from a ghost and catch up with Mr. Bone Jangles. Plus, a new mystery sound to discover!

Don’t forget to check out Forever Ago, where we have a companion episode to this Brontosaurus tale. It’s called The Bone Wars: A dino-discovery duel, and it’s all about two competing paleontologists, who get a little carried away.
