Why do the same, self-repeating patterns appear in trees, rivers, lightning, and even inside our own bodies? Is there some secret, hidden rule of nature or mathematics that makes these intricate designs appear all over the place? Let’s talk about fractals.

Shows like The Walking Dead are full of hungry, mindless, surprisingly fleet-footed armies of brain-eating zombies. Could they actually exist? Are zombies real? Well, maybe if you're talking about zom-bees! This week I introduce you to some of nature's strangest mind-controlling parasites, who make zombies of the natural world. This one will make your brain tingle. That's just the awesome science, though… not a parasite. Promise!

It would be a lot easier to study the science of dreaming if we weren’t asleep every time we did it. Why do we dream? What does dreaming do for our brains? How did dreaming evolve? Here’s a look at the current theories from psychology and neuroscience.

There are some startlingly black animals out there, whether they’re in the deep ocean or in the darkest corners of the rainforest. But humans have created some stunningly black substances too, using science and engineering. So who wins, nature or humans? In this video, I go in search of the blackest black things on Earth to see what’s really the blackest… and why.

Plants are the most important source of nutrients for pretty much all of Earth's animals, and many of the planet's bacteria and fungi too. Humans like them so much that we line them up in salad bars so we can feast upon their crunchy cronch by the plate full.
But plants don't always want to be eaten, ya know? Here's a look at some of our favorite plant flavors and how they are actually a form of chemical warfare

Who built the pyramids? The colossal geometric monuments found at Giza and elsewhere in Egypt are some of Earth’s most impressive constructions. Pyramids are truly wonders of the ancient and modern world.
But when the pyramids were built, the ancient Egyptians hadn’t invented the wheel, developed bronze tools, or discovered pi. How were they able to stack two million stone blocks, each weighing more than two tons, into precise geometric alignments that would survive more than 4,000 years and capture the imaginations of explorers throughout history? They did it the same way we always have: by trial and error. The true history of the pyramids is one of experimentation and science, not magic… or aliens.

Bees and flowers have an amazingly close relationship. Flowers need bees in order to reproduce, and bees need flowers to feed their colonies. Take away one, and the other would disappear too. It begs the question: When it comes to evolution, which came first, the bees or the flowers?

I’m guessing you’re pretty familiar with ice. We use it in our drinks, slip on it, skate on it, worry about climate change melting it. But have you ever stopped to really think about this stuff? The freezing and melting of water affects so much of our world. It’s ice crystals in thunderclouds that create lightning. Ice is powerful enough crack boulders, float stones, and alter entire landscapes. Ice is such a common substance, you'd think we'd know everything about it by now. But it has some secrets and weird properties we’ve only just begun to figure out. One question about ice that's, still not totally answered, is one of the most obvious: why is ice slippery? It's a more complicated answer than it seems!

Nuclear weapons represent the darker side of E=mc^2. Science has given us the ability to understand what will happen if these weapons are ever used again… and what will happen if they are *never* used again.
