12. Marijuana – Part I

Today’s show is Part I of a two-part episode, all about the science of Marijuana! (Don’t worry, we live in Oregon. It’s totally legal.) Today Kira and Keera cover:

  • Human’s millennia old history with marijuana
  • The specifics of the Cannabis species
  • What THC does to your neurons to gets you high
  • Science of drug addiction

11. Science News Quiz: October 2016

On today’s episode, Kira and Keera quiz Ed Hill and XRAY guest-host Emily Gillilia on their knowledge of the latest science news. Headline questions include:

  • What is so exciting about Dione’s underground ocean?
  • Scientists want to harvest the milk of what exotic species?
  • How are silk worms making unbreakable super-silk?
  • What’s the link between risk of mortality and having a sense of humor?

10. I Can Smell Your Genes From Here

Your sense of smell plays a big part in your attraction to potential mates. When you have a physiological response of attraction towards a person, chances are it’s because you, consciously or subconsciously, enjoy the smell of their B.O.

What is the science behind the scent of attraction? And how can you use it to find your soul (smell) mate?

9. Bacteria: Friend or Foe?

Bacteria cells in and on your body outnumber the human cells by ten to one.

You are a giant, human shaped pile of bacteria.

8. Milk!

In Keera and Kira’s first episode with Jefferson Smith, host of XRAY’s Morning Show, the ladies discuss the history and science of milk. Jefferson, on the other hand, internally questions whether or not he ever wants to do another show with 2 nerdy ladies who seem to be unusually enthusiastic about the science of dairy products.

Topics include:

  • What’s happening at the molecular level when cream becomes whipped cream?
  • Why are some people lactose intolerant? What features do lactose tolerant people possess that gives them the ability to safely digest dairy?
  • Is cheese really as addictive as crack?

7. Back to School

Kids are going back to school! Which means they’re inevitably going to come home with questions about science that you may not remember the answer to because, well, you learned them a long, long time ago.

In today’s episode we cover some of the basics of chemistry, biology, and physics, and how to make science exciting for both you and your kids. We also lay out some science experiments you can do at home, and how to explain them appropriately to little kids, medium kids, and big kids.

We also make Christine throw paper airplanes around the studio. So, your welcome.

6. The Energetic Cost of Living

Your body is almost always using energy, whether you’re going hard labor, or just sleeping. Play along with our Labor Quiz to see if you know the answers to questions like:

  • True or False: When you sleep your body consumes the caloric equivalent of 1 tablespoon of ketchup.
  • Thinking requires energy, so you burn a lot more calories thinking really hard
  • Celery is a “negative calorie food,” because it takes more calories to digest celery than you absorb from eating it.
  • It takes more energy to digest a sandwich made with whole wheat bread and real cheese than one made of white bread and American cheese.

4. Science Fiction Movies, In Spaaaaace!

Science Fiction movies are great. But for us, half the fun of watching them is how blatantly they misrepresent the actual science behind their plots. Its ridiculous, it’s inaccurate, and it’s a heck of a lot of fun to pick apart.

On today’s show, we listen to a few clips from some of our favorite science fiction movies, and focus in on one of the major inaccuracies, then give you three possible reasons why it wouldn’t have happened that way. Only one of the totally-plausible sounding scientific explanations is the right one. Can you figure out which it is before the DJs? 

Quiz: “You know they got it wrong, but do you know why?”

3. Metallic or Metallica?!

Is it a metal? Or is it METAL?!? (Like, the music. You have to say it with a growl to get the joke.)  In today’s show, K+K attempt to stump the XRAY DJs with phrases that might describe an actual scientific element and its metallic properties, or might be the name of a Metallica song.

Think you know your metals? Play along!

2. The Importance of Play

In the first official episode of Everything Is Interesting as its own radio segment, Kira and Keera (we called her Kay back then!) talk about the importance of playing, both for children and adults. Video games, playing outside, puzzles, science experiments, and “adult” play, build memory and reasoning skills, dispel aggressive behavior, promote social inclusion, and contribute to many facets of healthy brain development.

Because they are so dedicated to the healthy brain development of the XRAY in the Morning DJs, Kira and Keera bring a hands-on science game, making the crew spin raw eggs in the studio to learn about inertia, density, and drunk ballerinas.
