58. Sauer Power! (The Joys of Fermenting Cabbage)

So you’re ready to take the big leap, and start fermenting your own vegetables at home. Congratulations! This is an important time in any person’s life, and K+K want to make sure you have the support you need. In this episode, you’ll learn:

  • A fast, easy, and SAFE method for making sauerkraut
  • How to acquire good bacteria in your sauerkraut jar, without inviting in the pathogenic (a.k.a. icky) kind
  • What a “fermenting bacteria” is, and how they work their ferment-y magic
  • The epic-micro bacterial drama that plays out while you wait for your cabbage to become tangy, delicious, shelf-stable sauerkraut

57. Qualitative Analysis of a Dank Nug – Revisiting Weed Science

Back when they were young, nervous, and pressed for on-air time, Kira & Keera did an episode of Everything of Interesting about the science of cannabis and its constituent chemicals. Today they revisit the subject, armed with a lot more knowledge and far more confidence.

In this episode, K+K cover the difference between Indica & Sativa, how THC and CBD affect your brain, and whether or not nature wants us to get high.

56. The Science Behind Old Wives Tales

An apple a day keeps the doctor away.  Red sky in the morning, sailors take warning.  What can i say, sometimes its just easier to follow advice when it’s delivered in a rhyme scheme.

On today’s show, K+K & guest host Emily Gilliland explore some of the more modern Old Wives Tales, and discuss the science behind why they are or aren’t true.

55. Telepathy & Other Fun Party Tricks You Can Do With A Computer In Your Brain!

Have you ever moved things with your mind? How about communicated a thought telepathically, from your brain, directly to someone else’s brain?

If you’ve used Brain-Computer Interface technology, (or if you’re a Jedi) the answer is probably… yes! But if there were wires and a computer involved, does that count as true telepathic or telekenetic abilities? And will they let you into Jedi Academy with something like this on your head?

Keera Lindenberg & Joel Murphy, and the hat that sucks up brainwaves.

Thank you so much to Joel Murphy from OpenBCI for explaining the ins and outs of Brain Computer Interface, and for reading Keera’s brainwaves!

54. Artisanal Bug Soup – the Life of Carnivorous Plants

Science Fact or Science Fiction (the quiz game™) is back! On today’s episode, K+K test Keiren Bond on her carnivorous plant knowledge, with questions like:

  • Can a Venus Fly Trap count?
  • Would any plant eat bugs if you mushed them into an artisanal organic soup?
  • Would a pitcher plant prefer to eat a Montane Tree Shrew, or its poop?
“Today’s my day, I can just feel it!”

53. Black Holes Part 2 – Slow Motion Somersaults in Space

In part 2 of their exploration of these space oddities, K+K talk to guest host Emily Gilliland about what would happen if our sun spontaneously imploded, how anyone falling into a black hole would turn into spaghetti, and what it means to exist in time, but not in space. They even attempt to explain how, to an observer moving faster, time (literally!) moves slower, by making Emily do (proverbial) back-flips in space.

If you can’t tell which way is up, are you ALWAYS mid-somersault?

52. Black Holes 1 – Infinite Gumballs in the Frosting of Spacetime

Have you ever been falling into a black hole and thought, “how did this infinite curve in spacetime even get here, anyway?” Well, the next time you’re hurdling towards the infinitely dense Singularity, which exists only in time but not in space and is possibly a hole in the 4-dimensional universe, you can listen to this episode!

Objects in spacetime, or gumballs in frosting? YOU decide!

In Part 1 of their journey through outer space, K+K explore how Black Holes are formed, discuss the recent detection of their gravitational waves, and interview Isaac Newton and Albert Einstein about light, gravity, and the fluffy pink frosting of spacetime.

 

51. The First Life on Earth

It’s 4.5 billion years ago. The Earth is a hot, bubbling sphere of lava  & hostile gases. And then suddenly… THERE IS LIFE!

But how did this first Earthly organism show up on our planet? And who was (s)he? A Giant Virus? An archaea cell?

Meet your Great, Great, Great, Great, Great, Great, Great, Great Grandmother, Luca. 

If our earliest ancestor was indeed, as research suggests, a simple strand of chemicals that randomly happened to smush together in the perfect shape for fabricating its own decedents (also strands of chemicals) floating in a swamp of primordial ooze that was randomly struck by lightning… how did it evolve into the extremely complex multi-cellular plants and animals that exist today?

50. Hibernation: sleep ’til the pizza trees bloom

We’ve all been there: winter gets dark and cold, and the urge to curl up in bed and sleep through the harshest of seasons grows strong.  Unfortunately, if that’s how you tried to cope, you’d go from cold as a stone, to stone cold dead. Human biology just isn’t cut out for the task. Bears on the other hand, are masters of hibernation.

With the help of guest host David Zimelis, K + K show you why hibernation is more than just a snooze, and explore the incredible things bears do that allow them to curl up for months on end without food, water, or bathroom breaks (yikes!).
