27. Resistance Is Futile.

What goes through the mind of a bee? Does it have its own thoughts, or is being part of a hive-minded collective like being a part of the Borg?  Can an organism with swarm intelligence have a private identity, or does the community simply add each individual’s biological and technological distinctiveness to its own?

Lower your shields. Resistance is futile.

On this episode, Keera and Kira examine the decision making process in communities of bees, birds, neurons, and slime mold, and discover what life is like as part of a hive mind.

26. They’re Wet & Weird & Wild, You Make Them Come Alive…

Every now and then, Keera and Kira hang out and do stuff OTHER than talk about science. Like, sometimes they reminisce about growing up in the 90’s, and the strange toys and commercials and fashion that shaped their impressionable little minds.

That’s how K+K stumbled upon the Amazing Live SEA MONKEYS! Remember getting those eggs in the mail, and how excited you were for your microscopic primates to come alive with just a little water? Kira and Keera do!

On this episode, the Science Ladies talk about this aquatic crustacean species, Artemia salina, (Spoiler Alert: they’re not monkeys. Sorry.) as wells as where they come from, how they evolved, and why you can send them through the mail like a pack of tomato seeds. They also explore the story of Harold von Braunhut, the man who sold these little creatures as living magic tricks, and the science behind really good marketing. 

How to Make Your Own Aquatic World

On today’s Everything Is Interesting episode, we talked about Sea Monkeys (you’re welcome) and those neat little glass biospheres they live in sometimes.

The self-contained biospheres are both beautiful and amazing, because everything Sea Monkeys (spoiler alert: brine shrimp) need to survive is provided by their habitat. The shrimp, algae, and bacteria inside a self-contained biosphere complete a nutrient cycle loop, where all organisms are providing the oxygen, CO2, and nutrients that sustain the other organisms in the system.

As promised, here’s a link to some instructions on how to make your OWN aquatic biosphere.

*Note* We did not craft this document, it belongs to Anne Schultz. Thanks for letting us link to your instructions, Anne!


*Another Note*  Science Project has a glass biosphere that has been sustaining itself for the last 2 years! However, we used cherry shrimp because they require less salty water, meaning there’s more plants that will survive in a cherry shrimp habitat than in a brine shrimp habitat. If you live in Portland, OR, we happen to know that there are shrimp and plants at Pets on Broadway in NE!

25. Affairs Of The Heart (The Science Of Love)


It’s Valentines Day! So in true nerd fashion, Keera and Kira delve into the biochemistry of love. Why DO your palms get sweaty when you see the person your attracted to?

Also, they explore the heart throughout medical history. Why do we use the heart as the symbol for where love comes from, when we now know that emotions, thoughts, and sweaty palms all begin in the brain?

24. Volcanoes & Geysers & Lava, Oh My!

On today’s episode, Kira & Keera explore the immense geological forces that help to shape our planet, and then share some of the places you can go to see them, right here in our own National Parks.

Talking points:

  • LAVA!
  • The discovery of plate tectonics
  • The Cascadia Subduction Zone
  • How geysers form


On today’s episode, Kira and Keera quiz the XRAY team on the life and times of Amazing Arachnids! Can spiders get caught in their own web? Why DO spiders have 8 eyes? What would a 20 foot tall spider be like? And what would really happen if you were bitten by a radioactive spider?

The most cuddly thing on 8 legs.

Then in the last 5 minutes, we share some ways that you, the listener, can be active in our national democracy and advocate for science!

How to Be a Science Advocate

How to Be a Science Advocate: Your Guide to Standing Up For Science

Science at it’s purest is non partisan. Even when the way we use science becomes highly political, what we discover through science applies to the entire planet, and all the people living on it.

It’s not a matter of believing in it. Science just is. It’s the endless process of discovering how things work, so we can better understand the nature of the world. Even so, science and government end up intertwined.

If science matters to you, here’s a guide to to starting to influence public policy.

1) Know what legislation is being proposed, and pay close attention to which ones directly impact the scientific community.

  • Legislation moving through Congress is listed here:


  • The American Geophysical Union has compiled a list of which legislation and congressional actions will affect science research and climate change:


2) Know who your representatives are, and tell them what you think. Call them. Write them. Even better, if you can, show up in person and go to the town hall meetings they hold and speak up.

  • If you live in Portland, Oregon, your representatives are:
    • Earl Blumenauer: 202-225-4811
    • Jeff Merkley: 202-224-3753
    • Ron Wyden: 202-224-5244

These ideas have been compiled by Science Project, but partially submitted by community members. This document can and will change over time, as more Citizen Action Ideas come to light. For best results, use frequently! And share!

22. Solar POWER!

Today, Kira and Keera talk about the incredible power of that fiery ball in the sky, the sun! how we clever humans have devised the technology to harness it.

We also answer some of your burning questions (get it?), like:

  • What is nuclear fusion?
  • How does old dead plant matter become fossil fuels?
  • How do photo-voltaic cells capture sun energy?
  • What is artificial photosynthesis, and how do we make it happen?

Hot Pie On A Cold Day

On last week’s episode, we tried to tackle one of our listener-submitted questions about cold and winter. Specifically:

Why does hot food smell so good as the odors waft out windows on a cold crisp winter day?  Does the cold change the smells to make them stronger?

We didn’t have time to answer this one on the air, but we understand the burning desire for knowledge only quenched by evidence-based scientific data, and we didn’t want to leave you hanging. So here’s what we found:


Actually, it probably has more to do with how your brain perceives these smells than it does with the cold day having any affect on those smells.

When you get a whiff of garlic, what you’re smelling are these sulfur-based molecules in the garlic that evaporate into the air at very low temperatures. We call them volatile organic compounds, because they go from being a solid to being a vapor with very little impetus. This is why you can smell garlic that’s just sitting on your counter.

As the temperature of the air drops outside, these volatile organic compounds known as odors, slow down, and there are generally less of them floating about in the ambient air.  So there just isn’t as much to smell out there in winter, and what is out there isn’t nearly as potent.

Increasing heat increases the chance of the molecules escaping into the air, so as you say, cook the garlic, the odor increases. The hotter the air, the faster and farther the odor molecules can travel.  Additionally, increasing humidity traps these odor molecules and allows them to linger.

To help explain this better, imagine conditions opposite to what it’s like outside right now: a hot humid summer day. Ah, the lovely smell of an overflowing garbage can in the park on this staunchy afternoon. It’s pretty gross isn’t it? And powerful. That’s because odors intensify as the heat increases and as the humidity goes up, and conversely lose their intensity as the air gets cooler and drier.  

Our sense of smell dulls in the cold as well. Neurons called olfactory receptors line your nasal cavity, and are coated in a layer of mucus. Millions and millions of them. Each receptor is tuned to a specific odor molecule. So say, when a molecule of coffee wafts up to your nose, it binds to an olfactory receptor specific to receive and identify it.

The binding triggers the olfactory receptors to send electrical signals that are passed along to the brain, letting you know a sweet sweet hit of caffeine is nearby. When exposed to cold air, these olfactory receptors apparently “bury themselves” a little deeper, and become less sensitive.
So if food smells stronger and better in the winter, you’re probably just perceiving the smell of hot food to be more intense.  Since there are generally less odors just floating around in the winter to get in the way, wouldn’t the odor of the food just sort of…. stands out more.

21. Snowflakes

A raging ice storm has had most everyone in Portland trapped indoors, with nothing to do but listen to old episodes of Everything Is Interesting.  Visions of snowflakes dancing in their heads, K+K the science questions they dreamed up about cold weather, and the way snow forms.

They also asked listeners what snow questions they had been pondering, and got some pretty good ones! So here’s the answers!
