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.

Today we're talking about the biggest snakes that ever lived -- like anacondas, pythons, and Titanoboa -- and how they evolved to be so big in the first place.<b<br/>r/>

You may have heard of the Hobbits -- no, not the Tolkien ones. Our cousins, Homo floresiensis! But have you ever wondered why this enigmatic mini species was so little? Let's talk about the decades of research into what made the...

Identical twins may look exactly alike, but they differ in some pretty weird ways. In this List Show, we'll explore five of them. <b<br/>r/>

In this episode of Crash Course Biology, we’ll learn about the ways population genetics reveals how groups of living things evolve—by comparing genetic similarities and differences. We’ll discover the most genetically diverse species of...

Crocodiles, and birds, and dinosaurs—oh my! While classifying organisms is nothing new, phylogeny— or, grouping organisms by their evolutionary relationships—is helping us see life in a whole new light. In this episode of Crash Course...

As the political parties square off over numerous issues, many Americans are seeking ways to overcome division and distrust within their communities to address the issues that matter most to them. A program in Rhode Island is trying to...

Many crustaceans from all sorts of starting points evolve to end up looking similar, likely due to outside pressures. That’s sort of like what happens with YouTube videos.

Solar eclipses don't just happen here on earth - moons of other planets also pass between those planets and the sun, resulting in various types of solar eclipses on Mars, Jupiter, Saturn, Uranus, Neptune, and even non-planets like Pluto,...

While many researchers are focusing on finding a difference in brains of people with dyslexia, some new research suggests it might not just be in their brains, but in their eyes.

How Big Is The Sun?

SciShow Space takes you to the moon! Learn about the competing theories about how Earth's closest neighbor formed.

Every species on Earth has a fingerprint - whether or not they have fingers at all.

If a tree falls in space, and it's frequency is modulated by multiple octaves and digitized, does it make a sound?

While dinosaurs were dominating the land, the metriorhynchids were thriving in the seas. But taking that plunge wasn’t easy because it takes a very special set of traits to fully dedicate yourself to life at sea.

These relatives of ours lived in Eurasia for more than 300,000 years. They were expert toolmakers, using materials like stone, wood, and animal bone. They were also skilled hunters and foragers, and may even have created cave art. So...

Maybe it’s a little self-centered that we can be pretty focused on the DNA that we got from Neanderthals – but we shouldn’t forget that gene flow goes both ways.

The tree of life you learned in school is wrong, even if you just graduated. We like to sort eukaryotes into big kingdoms or supergroups, but scientists can't agree what those groups should be. Here's why that's a good thing.

For us terrestrial animals, sneezing is a regular part of life involving the movement of a lot of air. But animals that live underwater and don't breathe air like we do also sneeze. Sea sponges, corals, and hagfish use their snot to...

Plants don't make caffeine just for us, so what DO they make it for?

Today on SciShow we bring you a cool humanoid diving robot and insight into the evolution of the venus flytrap.

Time Magazine has called it "the most horrible drug in the world," and last month, it hit the US. Because seriously, why would you take a drug that rots your flesh, bones, and brain?! Hank Green discusses the science behind the street...

Sleep is complicated. And there's still a lot we don't know about it, but zebrafish larvae are a surprisingly good place to look to learn more about what makes us sleepy.

We're taught to be cool around strange dogs because they smell fear, and that might be true, but your fear is probably freaking them out too!
