According to the fossils we've found, it turns out the T-Rex may look different than what we thought! Join Hank Green for a fascinating dive into the past, and a realistic look at what the King of the Dinosaurs was actually like. Let's...

For a long time, we could only guess what color a dinosaur might be. But in the past decade, there has been an explosion of color.

Hank gets to the bottom of this "faster-than-the-speed-of-light-neutrino" kerfuffle, discusses some ancient stuff, and announces the winner of the award for worst science in a film.

We can learn a lot from dinosaur fossils, but figuring how they behaved is a real challenge.

From wasps nests to nuclear reactors. Here are just a few clever ways archeologists figure out how old something is.

Squeaks and Mister Brown pretend to go back in time to learn more about Trilobites, using special clues from fossils! Second Grade Next Generation Science Standards Crosscutting Concepts Patterns: Observed patterns in nature guide...

Hank brings you the SciShow news of the week. Recent record high temperatures and other extreme weather events around the world are climate change in action; a new fossil of an ancient human ancestor; some disturbing discoveries about...

Hank goes from space to sex and then to motherhood, covering the SpaceX launch, a mission to the moons of Jupiter, intersexual workplace rivalries, the evolution of male homosexuality, the fossil evidence of squishy baby skulls, toddler...

In the animal kingdom, sleeping can be dangerous. Lying completely motionless and unconscious for hours at a time is just asking for trouble. There are, however, some sleepy risk-takers who spend almost all of their days snoozing.

We've found plenty of dinosaur bones all around the world, but is it possible to find any fossilized soft tissues from ancient animals?

Newly described wormlike fossils dating back over half a billion years might be our oldest ancestors, and researchers have mapped and visualized the physical structure of the microscopic communities growing on human tongues!

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

We're back in Bozeman, Montana this week talking to Amy Atwater, Collections Manager at the Museum of the Rockies. MOR has among the largest collections of North American dinosaurs in the United States. We talk to Amy about her job and...

To ring in 2021, we want to celebrate some of the greatest minds in science — folks who have contributed to our understanding of the world and in some cases saved lives along the way!

Scientists have found fossils that show life appearing on Earth much earlier than we thought. Meanwhile, could there be a new fundamental force?

Whether they're dancing, hunting, or being a pain in the nose, these new arachnid species will knock all 8 of your socks off.

Some of the biggest evolution questions finally answered.

This week, scientists discover something in a fish fossil that might give us a hand in finding our earliest land-dwelling ancestors.

We don't need a time machine to learn from the past (but let us know if you find one)! Air bubbles trapped in ice for millennia and ancient pollen grains can tell us a lot about climate shifts hundreds of thousands of years ago!

Today, penguins are found mainly in the Southern Hemisphere. But fossils have revealed giant lookalikes to these swimming birds further up north, spurring questions of how they evolved and what happened to them.

The microraptor was a four-winged carnivorous dinosaur with iridescent black feathers. But if our information about this dinosaur comes from fossils, how can we be certain about its color? Len Bloch shows how making sense of the evidence...

Dickinsonia might be the oldest known member of the animal kingdom, and the origin of birdsongs from the syrinx might be a little less mysterious.

You probably remember the T.rex's iconic roar from Jurassic Park, but it turns out that dinosaurs actually didn't sound that ferocious.
