Synthesizers are a very recent invention, especially when you compare them to acoustic instruments, like pianos and guitars. In this episode, we learn how these machines with keys, knobs, switches, buttons and sliders actually make sound. We’ll also travel back to the 1960’s and hear how synth pioneers like Bob Moog helped bring these sound making devices into the mainstream. Plus, we’ll check in with Suzanne Ciani, who has been using her synthesizer to create iconic sounds for movies, television and video games for over 50 years! All that plus a striking Mystery Sound and Moment of Um that answers the question: Do airplanes have a speed limit?

If habits are really stuck, we don't think much about them -- we just do them! Some habits are good (like brushing your teeth in the morning) and others are not as good (like biting your nails).

Today we find out what parts of our brains help us form habits and why it's actually super useful to not have to think so hard about everything. Gungador tries to break a bad habit, and we find out the best tips for ditching habits we want to leave behind.

Plus: A brand new mystery sound and a Moment of Um that answers the question: "How do 3D glasses work?

We’ll be back with new episodes in January. But we wanted to share another show with you that we’ve been working on: Smash Boom Best!

It’s a debate show where we take two cool things, smash them together and let you decide which one is best. Today we’re sharing with you an excerpt from a debate featuring our very own Sanden Totten: Flowers vs Rainbows

Sanden is repping team flowers and our good friend Joy Dolo, host of Forever Ago, is arguing for team rainbows.

To hear the rest of the debate, find Smash Boom Best wherever you listen to podcasts. There are over 30 debates ready for your binge listening this holiday season! Play along at home by yourself -- or with your family! You can find score sheets and other fun stuff at smashboom.org

Having a sibling is a special thing -- but, wow, can they be annoying! In this episode we’ll look at why our brothers and sisters are so good at pushing our buttons.

The flu shot changes every year. But why is the flu special, if other illnesses have much longer-lasting vaccines? This episode takes us into the world of viruses and immunity.

We released this episode about flu vaccines last year but we wanted to share it with you again since it’s flu vaccine season but also because vaccines are in the news a lot lately. Scientists are testing a bunch of vaccines for the new coronavirus right now. This episode gets into the details of how vaccines work and how they’re made.

A friendly lymphocyte fills us in on how flu shots work, and science journalist Anna Rothschild shares how vaccines started around the world. We'll hear from some virus-busting detectives to see how scientists solve the case of how to make next year’s flu shot as effective as possible. Author Maryn McKenna will stop by and drop some flu knowledge, too!

Get your ears ready for a good, thumping mystery sound, and a new Moment of Um: how do straws work?

How are mountains made? What causes an earthquake? How does hot lava come bubbling up? The answer in each case is…tectonic plates!

These are giant, moving slabs of rock covering the Earth’s surface. When they slide past or smash into each other it shakes the planet. But, they also helped shape the land we live on.

Find out how they work with an extreme cooking demonstration (you’ll never see peanut M&Ms the same way). Meet the scientist who thought long ago all the continents were smushed together in a super-continent (spoiler: he was right!). Plus an interview with a USGS scientist about what our planet might look like in a million years.

All that plus a mystery sound and a Moment of Um about stinky breath. Listen up and rock on!

In this second episode on bees (a bee-quel, you might say!) we’re taking a look at pollination: the many pollination talents of different bees, why pollination is so important, and what you can do to help wild bees! 

The tables are turned in the Mystery Sound department: our beekeeping cohosts have a sound for Menaka and Sanden to guess! And the Moment of Um answers an age-old stumper: how are alligators and crocodiles different?
