We've been using lab rats for over a hundred years, and they've been part of some of the biggest medical breakthroughs ever. But what comes next? From organs on a chip to computer simulations, here are some of the ways that science...

In the history of space travel, there are a few famous animal astronauts (or cosmonauts), like Laika the dog and Ham the chimpanzee. But you might not have heard of Félicette, who in 1963 became the first -- and so far only -- cat to...

Today, rats are often regarded as the most successful invasive species in the world. The most common species of rat scurried onto the scene roughly 1 to 3 million years ago in Asia. There, they craftily survived Earth’s most recent ice...

Epigenetics: Why Inheritance Is Weirder Than We Thought

Do We Have to Get Old and Die?

Scientists have recently discovered the cells responsible for a deer's amazing ability to regrow antlers in just a few months. It may be the key to healing human wounds and broken bones faster.

If you've ever watched an animal sleep and wondered what they're dreaming about, science has the answers.

Platypuses are so funny, it looks like someone made them up as a joke. But they're real animals! Join Jessi and Squeaks to learn about how amazing platypuses really are!

SciShow’s hot take: Peppers don’t produce that spicy goodness for the reason you think!

Bivalves—animals like mussels, clams and oysters—might be a more familiar sight in a restaurant than a lab. But it turns out that studying them might help us learn more about our own health.

A lot of our videos include the disclaimer "Mice aren't people." But why do we keep saying this, and if rodent studies aren't effective, why do we keep using them?

Drugging animals may seem like a bad idea, but you'd be shocked to learn what it can teach scientists about disease, biology & animal behavior! Join us for a new animal-focused episode of SciShow, hosted by the one and only Hank Green!

Hank tells us some of the surprising things that could be causing or contributing to the obesity epidemic.

Humans are pretty good at destroying things. Like habitats, animal populations... you catch my drift. But, there have been a few species that humans have helped bring back from the brink of extinction.

Check out Ms. Spider Hat and five other new species scientists have discovered and classified in the last year!

Many animals use the same five senses as we do, but these creatures take that beyond the next level.

Guest Dr. Angie Luis is here to tell Hank about what happens when wildlife spreads diseases to humans—as we know from history, it can get ugly. Joining them is Jessi, who brings some wildlife that's totally unproblematic! Learn more...

In this episode of Crash Course Psychology, Hank talks about how we learn by observation... and how that can mean beating the tar out of an inanimate clown named Bobo. -- Table of Contents Limitations of Classical and Operant...
