When particle physicist John Huth was briefly lost at sea, he started to wonder how the people around the world who navigate vast oceans figured their way around. What started as an afternoon activity gone awry led him to a years-long research journey, meeting many Pacific Islanders, expert navigators, and other researchers, hoping to crack the puzzle of open ocean navigation. And the key to all of it lies in these ancient stick charts, a non-writing form of communication passed down for generations. Here's how these charts and the observations of expert navigators are teaching physics researchers all about the motion of the ocean.

Even though cleft lips and palates are really common, there's still a lot of research that needs to be done into why they form. But scientists have found a whole new line of evidence that might crack the case wide open, and it's in dog DNA. Here's the story of how the Turkish Pointer may be able to point us in the direction for understanding how and why clefts form.

Most cultures who developed metalworking technology never let the skill go to waste. But in what's now Michigan, Native Americans started making metal tools well before anyone else did, and then stopped. And the reason why this happened is hiding in the very metal that they were working: Copper. Thanks to Alexis Dahl for joining us on this episode.

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!

The James Webb Telescope just took a photo of a newly discovered exoplanet. Exciting stuff but the raw image just looks like a small, faint dot—not a fully detailed world. The question is, just how big would a telescope need to be to actually see an alien world in detail? Let’s explore diffraction, resolution, wild telescope tech, and one mind-blowing idea that could change everything.

This is the first-ever video of what we’re calling the "hermit crab caterpillar"! We’re pretty sure this strange caterpillar is a NEW SPECIES. We went to the Peruvian Amazon to see amazing things, but we never expected this :)
But that makes me wonder: What *is* a species anyway? And how do you know if you’ve found a new species?

Of all the species that humans have domesticated, dogs are our oldest animal friends. But how did a group of wolves become the furry pup at the end of the bed? New research is finally unlocking the paw-in-hand evolution of dogs and humans. In this episode we’re answering one big question: Did we domesticate dogs, or did dogs domesticate us?

Special thanks to our friends from MinuteEarth!

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.

Glacier ice is weird. It’s solid. Solid things aren’t supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? I traveled to Mendenhall Glacier in Juneau, Alaska to find out.

Special thanks to Josh Cassidy from KQED’s Deep Look for joining me in Alaska and shooting this episode! ► https://www.youtube.com/user/KQEDDeepLook

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.
