Hold on to your butts. This episode is about… butts. The science and evolutionary history of your rear end, the down-low on your derriere, shining a little light where the sun don't shine… you get the picture. But(t) seriously, we don't talk about this all-important hole enough, and how, from an evolutionary perspective, it might be the most important orifice on your body.

There’s a lot of confusion out there about what is and isn’t a dinosaur. And you’d be forgiven for being kinda confused. Maybe paleontologists are just messing with us. Or… maybe the question of what is and isn’t a dinosaur goes deeper than we think? Well, like an intrepid fossil hunter, I set out to dig up an answer, and what I found teaches us a lesson about how hard it is to build a picture of the past when you only have a few puzzle pieces and a lot about why we classify things the way we do.

Why is the universe organized the way it is? And why is it so empty? From planets and stars to superclusters and galactic filaments, the universe’s largest structures formed because of its smallest. In this special collaboration with PHD Comics, we’ll learn how the earliest, quantumest blips seeded the structure of everything everywhere.

Uploaded 07-10-19
Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in our species’ history. But Earth’s climate has changed before. How do we know that this time we’re the cause? We know thanks to tiny bubbles of ancient atmosphere trapped in ice. #climatechange #globalwarming

Why the forest is more than the trees
SUBSCRIBE so you don’t miss a video! ►► http://bit.ly/iotbs_sub
Walk into any forest, and beneath your feet is an elaborate social network that helps make life on Earth possible. It’s called the “Wood Wide Web”, a massive and intricate network of fungi that exchange water, nutrients, and chemical signals with the plants they’re living in a symbiotic relationship with. This network of fungi is essential to the health and function of forests and to controlling climate change itself. You’re about to look at fungi in a whole new way!
