40. Did We Start the Fire? If Not, How Long HAS It Been Burning?

Humans love fire, in the form of BBQ or combustion engines.  A raging forest fire, however, can be devastating for our flimsy wooden human houses. Why then, is it so important that we let them burn? In this episode, the Science Ladies uncover:

  • How fire has been shaping ecosystems since long before any human ever lit a match
  • The forest-dwelling pyromaniacs that thrive in the flames, and why these species need fire to survive
  • What fire really is, and how it burns
  • The science behind putting out a fire (or, “How to not burn down your kitchen”)

39. The Placebo Effect

It’s not just conjecture: placebos work. The question is… how? Why is it that many diseases and physical ailments can be cured just as well with a sugar pill as they can with clinically tested medicine? K+K examine a case of mysteriously healed Parkinson’s Disease, talk about a doctor curing chronic pain with peppermint candies, and take a look at what happens in a person’s brain when they believe they’re receiving medical treatment… but aren’t.

Yum.

 

 

 

 

 

38. The Eyes Are The Window To The Retina.

Human eyes are pretty impressive, but let’s be honest, our ocular organs don’t hold a candle to the eyes of animals like owls, mantis shrimp, cats, eagles, dragonflies, octopuses, bees, parrots, goats, chameleons… Ok, maybe human eyes aren’t all that impressive after all.

They’re eyeballs.

Today K+K discuss:

  • The anatomy of the eyeball
  • Color and light wave perception (what is a color, really?)
  • How to see with amazing precision at a distance, or at night (hint: become an owl)
  • The amazing mantis shrimp (who may not actually be as amazing as you’ve been told, but then by the end you’ll think they’re amazing again)

37. I Used to Call You On My Cellphone.

Isn’t it wonderful that we can own cellphones, use them to call our mothers and look up photos of dogs in hats and locate the Chipotle nearest to us, and we never even need to know how they work? (Spoiler alert: we’ll tell you how they work in this episode.)

Do you get it yet?

Join K+K to explore:

  • Where the your voice goes when you speak into your cell phone
  • How sound waves become light waves just to become sound waves again
  • The language of satellites and cell phones
  • Why Drake is so sad
  • What the heck Trilateration is, and how you might use it if you were a wizard

36. Human Evolution (A Brief Overview)

We humans are pretty fortunate. Our intelligence and physical features are a result of the evolutionary hand we’ve been dealt, and are what have allowed us to build an advanced society with sophisticated infrastructure.

Get it?? The HAND we’ve been dealt??

Despite what you may have learned from 2001: A Space Odyssey, genetic changes, which produce physical and behavioral changes, don’t happen overnight, propelled by the power of a giant Monolith. Adaptations like walking upright, dexterity, and large complex brains, took millions of years to develop, and required the right environmental conditions for these random genetic changes to be considered assets. Join Kira and Keera on the journey of just how, and why, our ancient primate ancestors became… us.

35. 6th Grader Questions, Part 2

In a special “Listener Question” episode of Everything is Interesting, K+K answer some excellent inquisitions, sent in by the kids from Mrs. Pace’s 6th grade class at Pleasant Valley Middle school in Vancouver, Washington. The question writers brought up some super interesting topics, and we wanted to answer them all, so we broke this one up into 2 separate episodes. On today’s show the science ladies tackle:

-How the Earth was formed
-Why the Earth’s axis is tilted
-Where Earth’s water came from
-The first plant to emerge on Earth
-The number of endangered species on Earth
-The temperature on the moons of Neptune

-Geese vs. Swift formations
-Why we have droughts
-How Magnetic Levitation works
-How much gasoline humans use
-How trees make Oxygen
-How moss reproduces

33. Bad Science Fiction Movies #2

If there’s one thing we love, its ruining movie night for everyone by informing them of all the horrible science in wonderful movies. Play along with our 2nd Bad Science Fiction Movies Quiz, and see if you can pinpoint the scientific slip-ups in Transformers, The Core, Spider Man, and The Matrix.

32. Allergies

Are you suffering from a stuffy nose? Itchy eyes? Endless sneezing? Overall-dear-god-why-won’t-it-stop-misery? It could be the flu… or it could be allergies! On today’s show, K+K explore our immune system’s response to airborne pollen, the specific mechanisms inside the body that make those of us with allergies feel so awful, and just why the immune system attacks innocent little pollen in the first place.
