One day around 15,000 years ago, a wall of ice 2,000 feet tall and 30 miles wide suddenly broke wide open, and it unleashed the largest flood that we know of in the history of Earth. Come and hit the road with me as we search for the geologic fingerprints of the Missoula Ice Age Floods, and learn the story of one of the worst natural disasters that’s ever happened!

High fives to Nick Zentner for educating me on the geology of Eastern Washington. He makes incredible geology videos on YouTUbe:

Got a bad habit you just can’t seem to break? That’s because it’s literally wired into your brain.
Every single thought, action, and feeling changes your brain. When repeated enough times, a habit is formed. This week we’ll talk about how an advertiser in the early 1900s got half of Americans to pick up a new behavior - and make it a habit we all know today.

What have we learned from exploring Earth’s harshest locations? That pretty everywhere we look for life, we find it. From smoking hot hydrothermal vents to icy deserts, up in clouds and inside rocks, extremophiles have found a way to survive. These survivors and adapters are not only teaching us about life on Earth, but expanding the possibilities of where life can exist elsewhere.

We all breathe the same air. Literally.
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub

Take a deep breath. Smell that? It could be a little eau de Einstein. Or maybe a whiff of Cleopatra. Here's an amazing thought: every time you breathe, you could be sharing air with everyone who's ever lived. A few million of the same air molecules that enter your lungs in a lifetime also entered Albert Einstein or Marie Curie's lungs! That's some smart air.

Earth's atmosphere is big, but not as big as many people think. All the air that keeps us alive is just a thin candy shell around our planet. In this episode, echoing the words of John F. Kennedy, I'll show you the science of how we all share the same air. So let's be careful about what we're putting in it!

Are humans nature’s greatest architects? When we look elsewhere in nature, we find some pretty amazing animal architects. Species like ants, termites, prairie dogs, birds, and more have engineered some incredible structures. This week we look at how a few of these species have mastered physics to install air conditioning in their homes!

If you tried to sum up the last 150 years or so in one image, a chart of exponential growth would be a good place to start. It shows that some things change faster over time. You could apply it to life expectancy. Or compound interest. Or any number of things. But especially population growth. Back in 1798, a guy named Thomas Malthus noticed that not everything grows this way. And this caused people to worry because they were sure it would lead to massive death and starvation and famine. But that didn’t happen, thanks to something called the Green Revolution and a guy named Norman Borlaug. As we face a future population of ten billion and a world impacted by climate change, how will we do a Green Revolution 2.0? #GatesPartner

We've heard news of "peak oil" and "the end of the oil age" for years now, but we keep coming up with ways to find and pump more of it to the surface. Rising CO2 levels and the changing climate that results from burning fossil fuels mean that we should probably stop using oil sooner rather than later, though
Let's take a look at history and see how we've used different fuels, so that we might figure out when and how to make oil a thing of the past

Bees see the world in some very interesting ways
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub

To begin this video, we launched a little confetti to celebrate the fact that I am now "Dr. Joe", since I successfully defended my Ph.D. in molecular biology! Woo! But you don't have to call me "Doctor."

Anyway, spring is in the air!! We're all thawing out from winter's chill, and for bees and flowers this season is about one thing: Feeding and fertilizing. Bees are amazing social insects, and their relationship with flowers is one of nature's coolest examples of "mutualism". It got me wondering: How do bees see the world? Enjoy this look at how bees see in ultraviolet and even sense electric fields!

As more and more parents are choosing not to vaccinate their children or are vaccinating them later, diseases like measles are making a comeback. What's behind this antivax movement?

This week we look at why are people afraid of something that has saved so many lives, and the history and science of vaccines. #vaccine #antivax #measles

Crashing a car is usually not a good idea. But sometimes, it can save lives.
↓↓↓ More info and sources below ↓↓↓

No one ever wants to get in a car crash. But if you ever do, be very thankful for the engineers who crash test cars. You may have seen crash test simulations on TikTok using physics engines like BeamNG but I promise you they are nothing compared to the real thing! Join us for this DEEP dive into the physics of car crashes and the ways that engineers hack Newton's laws to keep you safe.

Head to Physics Girl for electromagnetic explosions! https://youtu.be/AXOa66-k9MA

Musical tesla coils are awesome. I went to visit Arc Attack, the legendary musical tesla coil band, to find out how they work (and to stand in between them!) I brought my friend Physics Girl along too

Step inside the Tesla coils in this 360 video: https://youtu.be/2SNcbNlbyVo

“In Our Nature” is a NEW special limited series on It’s Okay To Be Smart!
We’re on PATREON! Join the community ►► https://www.patreon.com/itsokaytobesmart
↓↓↓ More info and sources below ↓↓↓

Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living systems. In episode 4, we look at some surprising ways that species use teamwork in order to survive. Why is one African tree full of ants? Why are there birds nesting in girafe armpits? What surprising guard animal keeps an endangered butterfly larva from becoming wasp food? Welcome to the world of mutualisms and animal partnerships.

In Our Nature is a special miniseries produced by It’s Okay To Be Smart for PBS. Stay tuned for more episodes coming this summer, here on our YouTube channel!
