S12 E14 - 11m 17s
Nature has had to come up with some crazy ways to survive harsh winters. But none are weirder than hibernation. Turns out there is more than one kind of hibernation, and studying all these ways that life slows down in the cold might help humans one day become an interplanetary species.

The Paradox of Voting
S12 E13 - 12m 40s
Political scientist Don Green joins Joe to figure out the complex psychological and social factors that motivate us to vote - or not to.

And why it’s important to vote!

Why Do We Hate Certain Sounds
S12 E12 - 16m 27s
Ever wonder why certain sounds make us cringe or even feel sick? Join Joe as he reacts to some of the most hated sounds, from nails on a chalkboard to the infamous "moist," and explores the science of why these sounds are so unbearable to so many and how they can impact our lives.

The Sun is NOT the Center of the Solar System
S12 E11 - 11m 43s
Despite what you may have heard or learned in school, the sun is NOT in fact the center of the solar system. And it won’t be until 2027… But this being a science channel, you might be thinking “What the heck is this guy talking about? Of course the sun is the center of the solar system. We’ve known that for more than 600 years.” Like most things in science, it’s not quite that simple.

Why You See Faces in Things
S12 E10 - 10m 23s
Have you ever looked at a cloud and seen a face? Or the front of a car and seen a face? Or an electrical outlet and seen a face? You definitely have. We all see faces everywhere we look thanks to a fun quirk of the human brain called visual pareidolia.

Why trees look like rivers and also blood vessels and also lightning…
S12 E9 - 10m
Why do the same, self-repeating patterns appear in trees, rivers, lightning, and even our bodies? Is there some essential, hidden rule of nature that makes these intricate designs appear all over the place? Let’s talk about fractals.

The Real (Weird) Way We See Numbers
S12 E8 - 15m 25s
Would it surprise you to learn that fish and birds count in pretty much the same way that we do? And that infants can do math? Our animal brains deal with quantities in very specific ways, from quick counts of a few dots to how we perceive larger numbers. This "number sense" impacts our psychology, history, and behavior in the most fascinating ways.

The Surprising Power of Sex in Evolution
S12 E7 - 8m 46s
We all know Charles Darwin's theory of evolution, right? Natural selection? But what about his lesser-know theory of evolution: sexual selection. Let’s talk about how animals like peacocks, whose eye-catching physical traits make them evolutionarily stronger, even though their flashy looks make them more vulnerable to predators. Hint: it’s all about the chemistry.

Computers Can Predict When You're Going to Die… Here's How
S12 E6 - 12m 54s
Predictive analytics uses math and historical data to make predictions about the future. It’s used in commerce, sports, politics, social media and tons of other places. And as it turns out, people have been using math to predict people’s death for centuries. Can it predict mine?

Can AI Help Us Talk to Whales?
S12 E5 - 21m 33s
New technology is revolutionizing how we study and protect nature. In this video, we’ll learn how artificial intelligence is being used to decode the sonic landscapes of the ocean - specifically, whale song. That’s right, there may come a day soon where AI allows us to understand and talk to whales. But some scientists are saying: the question may actually be, SHOULD we talk to whales?

Measuring the Universe With a 14-Billion Light-Year Ruler
S12 E4 - 10m 40s
Since the time of the ancient Greeks, scientists have been constructing a cosmic measuring tape to measure the universe from our own backyard all the way to its ever-expanding edge: the cosmic distance ladder. In this video, we climb that ladder and explore how each rung has revealed something new and previously unthinkable about the universe we live in.

Why the 2024 Solar Eclipse is Such a Big Deal
S12 E3 - 15m 17s
On April 8, 2024, the Moon’s shadow will fall on Earth, creating a total solar eclipse across North America, and if you have the chance to see it, you don’t want to miss it. It’s an amazing coincidence that total eclipses happen at all — and that we’re alive at a time when we can see and predict them. So join us to find out everything you need to know to watch it.
