Modern-day Ohio is more than 600 kilometers from the ocean - yet it has thousands of ocean fossils dating back to the Ordovician, giving us a glimpse at its past under an ancient, fishless sea.

Bones are hard to digest and can be downright dangerous to eat, but some animals have evolved pretty bizarre adaptations to accommodate their crunchy, splintery diets.

When you think about the deep blue sea, you might instantly think of whales or coral reefs. But spare a thought for giant clams, the world's largest living shellfish. These incredible creatures can live to 100, grow up to four and a half...

When photographed under a 3D microscope, grains of sand appear like colorful pieces of candy and the stamens in a flower become like fantastical spires at an amusement park. Gary Greenberg reveals the thrilling details of the micro world.

It seems like birds would want to hide their eggs, but there are hundreds of species that lay blue to blue-green eggs. Thanks to some clever experiments, we’re finally starting to understand why birds might benefit from conspicuously...

Talk Show all-star Kallie Moore returns to tell us about the exciting things happening over at Eons, and Jessi stops by with not one but two poke-y guests!

What is the world's favorite fossil? Why the orthoceras of course! Hank will tell why that is in this episode of SciShow. Find out how you can get your very own orthoceras fossil.

Are parrots just good at imitating sounds or is there something else that separates them from other birds?

Despite their iridescent colors and smooth shapes, pearls are actually made of the exact same material as the craggy shell that surrounds them. Pearls, urchin spines, the shells of mussels, snails and clams, even coral— all these...

Deep in the Indian Ocean, scientists have discovered a snail whose feet are covered in iron scales, but how it builds these scales is a bit of a mystery.

Hank brings us the story of the electron and describes how reality is a kind of music, discussing electron shells and orbitals, electron configurations, ionization and electron affinities, and how all these things can be...

Several cultures portray the world as being carried on the back of a giant turtle. As it turns out, sea turtles really do house an entire world on their backs — one of microscopic organisms, that is!

You may think of single-celled organisms as being microscopically small, but these ocean dwellers are a little heftier than that.

SciShow explains what makes atoms bond (and what makes them sometimes seem promiscuous).

Antarctica wasn't always covered in kilometer thick ice sheets, in fact, scientists have spent years figuring out what turned this once lush continent into its current icy state.

In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law...

From Mendeleev’s original design to physicist-favorite “left-step” rendition, the periodic table of elements has gone through many iterations since it was first used to organize elements 150 years ago - each with its own useful insights...

In this video Paul Andersen shows how carbon dioxide in the atmosphere is causing a decrease in the pH of the oceans. The carbon dioxide combines with the water to create carbonic acid which dissociates into bicarbonate and carbonate...

Scientists often use the phrase “anatomically modern humans” to describe the point when our ancient ancestors looked like us. But when did humans become behaviorally modern?

Have you ever put a seashell up to your ear and heard a roaring sound the sounds sort of like the ocean? Is it magic? No! It's science! Jessi and Squeaks explain what's up!

Jessi and Squeaks look at some amazing creatures that they found in their garden: snails and slugs!

Island and coastal nations need to protect their waters to keep the oceans healthy. But they often have lots of debt and aren't able to prioritize ocean conservation over other needs. Mark Tercek and his team at The Nature Conservancy...

The octopus is a pretty odd animal under even the most ordinary circumstances – or ordinary by octopus standards, at least. So when folks start calling out one type of octopus as the strangest, there’s probably something special about...
