Ready for some mystery? This Smash Boom Battle takes on two famous places: the Bermuda Triangle and Loch Ness. Which is cooler? Is it the Bermuda Triangle -- a puzzling patch of ocean where ships, planes and plenty of people are said to have disappeared? Or is it Loch Ness -- a Scottish lake best known for spooky sightings of a long-necked creature? Listen to hear what our judge decides and then head over to smashboom.org to share your opinion with us!

What’s in your water, and how did it get there? Clean water is a must, but modern living can put a lot of bad stuff in it. Road salt, fertilizer, dog doo-doo, heavy metals - how do these things get in our water? Why should we care? And how can we tell if our water is healthy? In this episode we hitch a ride on the water cycle with a pair of water drops. We learn about what caused the Flint water crisis. And we hear about one young girl’s award-winning idea for a faster way to test lead in water - spoiler alert - it involves carbon nanotubes! This is the first in a series of water-related episodes we’re working on over the next few months. We hope it makes a splash with you!

The near 24-hour-cycle that keeps us on track is conducted by the suprachiasmatic nucleus. It’s a tiny part of our brains, but it’s super, super important.

In this episode we ponder some big questions from Brains On listeners about the vastness of space.

A few weeks ago, we got two emails that were so similar and so intriguing we had no choice but to investigate.

There are all kinds of volcanoes all over the world, but how are they formed? And how do they erupt? To find out, we’ll travel to the center of the Earth, and we’ll meet a NASA robot that’s going on a very special volcano mission.

You know those beeps in old NASA recordings? They’re called Quindar tones. This episode explains them and talks to a couple musicians who incorporate archival, NASA recordings into their songs.

In this episode we learn about Mars’ ancient past, meet an architect hoping to build cities there and we hear from Mars itself, thanks to the planet’s video blog, of course.

There are some basic ingredients to make thunderstorms and tornadoes. We’ll find out what they are – and how to observe these powerful and amazing storms safely.

To help us understand sunburns, we’re going deep into the skin to look at cells, molecules and electrons.

It’s time for the next Brains On debate! This intense matchup brings us to the depths of darkness, under the water and beyond our earth’s atmosphere. Who will prevail?

Our planet needs some carbon dioxide, but cars are pumping more into the atmosphere than our carbon cycle can handle. We’ll explore what all this carbon means for our planet. And we talk to a scientist who is working to change how we fuel our cars, so we can cut back on all this carbon dioxide.

If you’ve ever been the ocean, you’ve tasted that salt. But where does it come from? And why aren’t lakes and rivers salty too? A sea shanty is probably the best way to explain, right?

Fossil dating is a lot like eating a delicious ice cream cake. Well, sort of. We find out how scientists look at the rock and elements AROUND a fossil to figure out its age. Plus: We talk to a scientist who studied one of the coolest fossils discovered recently: a dinosaur tail trapped in amber, complete with feathers!

We don’t know much about the long life of a sea turtle, since it’s mostly spent in the ocean. When they do come ashore to lay their eggs, we know the babies use the moon and stars to guide them back to sea. But what happens when hotels and houses and streetlights compete for their attention?

The desert is hot, dry and deadly. But plenty of plants and animals thrive there. How do they do it? We’ll learn the tricks trees, bats and roadrunners use to make it in Joshua Tree National Park in California.

When an avalanche happens at the Great Sand Dunes in Colorado, it sounds like the sand is singing. Huh? How? Why? We learn about the special sand and the specific conditions that make this acoustic phenomenon possible.
