Six-foot millipedes? The biggest apes ever? And a kangaroo too big to hop? These are just a few of the biggest animals of their kinds to ever exist, and they're not just big, they're WEIRD. So let's talk about why Gigantopithecus went...

Dams are great for humans, providing hydroelectricity and flood control. They're also horrible for the rivers they block. Here are three success stories of ecosystems that bounced back after a dam was removed.

If you've ever had lice, you probably think of them as a temporary annoyance. But for the salmon industry, these pesky invertebrates cause real damage. So here are some of the wildest ways that science helps us fight these...

Optimal foraging theory means that turning down food is sometimes more efficient than eating it - but even then, what’s “wasted” doesn’t necessarily go to waste.

In 2023, a whole bunch of orcas started attacking boats off the coast of Spain. Was this the first battle in an all-out interspecies war? Well, probably not. But it's a pretty neat look into how trends come and go in orca pods - like...

Most of us can only see certain wavelengths of light our entire lives. So why can salmon switch on night vision? We'll learn how they can reshape their eyes to see into the infrared.

Brit Garner, host of SciShow Psych, talks about the research she's doing in conservation genetics/genomics, and Jessi from Animal Wonders shows off an African crested porcupine!

In this week's news, Hank explains how earthworms are doing nanotechnology for us, Americans will soon be eating genetically modified salmon, the Russians are going back to space, and another reason to drink less soda.

A little over a decade ago, a neuroscientist found "significant activation" in the neural tissue of a dead fish. While it didn't prove the existence of zombie fish, it did point out a huge statistical problem.

If you’ve ever eaten it, you’ve probably noticed how flaky fish can be. Poke at it with your fork and it just falls apart — no knife required. What makes fish different from other animal protein?

What swims in rivers and the ocean and is an awesome parent? Jessi and Squeaks talk about the amazing life cycle of salmon.

Salmon make a hardcore journey upstream to their spawning grounds to reproduce, and it almost always ends with death. But some live to reproduce again, and more than once!

Pods of killer whales inhabit the waters of every major ocean on Earth. Each family is able to survive thanks mainly to one member, its most knowledgeable hunter: the grandmother. These matriarchs can live 80 years or more and their...

When the ocean changes, the planet changes -- and it all starts with microbes, says biological oceanographer Angelicque White. Backed by decades of data, White shares how scientists use these ancient microorganisms as a crucial barometer...

Scientists are beginning to notice that more and more species are missing an essential vitamin, one that is crucial for their survival.

From the starter plants in your window to giant agriculture, there's a lot of science to cover before dinner.

Should I refrigerate my eggs or keep them out on the counter? This depends on where you live, and what egg practices your country follows.

Oxygen is so essential for animals that every multicellular species we’ve ever studied has the ability to use oxygen to create energy... except one.

Fish-eating trees sound like they’re straight out of science fiction. But they’re a real thing—one that exists right here on Earth. And they show just how interconnected life on this planet is.

Mister Brown and Squeaks are learning all about different cycles, or patterns, as they get ready for summer!

After World War Two, the applications of basic discoveries in biology took off—and became big business. Today, we’ll look at the rise of Big Pharma and GMO foods. We’ll also discuss how life-science technologies fundamentally changed...

Why do salmon use Earth's magnetic field to find their birth stream, only to die after spawning? Why do caribou traverse thousands of miles? This is the dramatic story of animal migration—a tale of life, death, and the survival of future...

What do we mean when we say that Native Americans have a strong connection to the land? In this episode of Crash Course Native American History, we’ll explore how Native peoples’ long, deep history on their homelands informs their...

The role that sustainable fishing has for a healthy national food supply. The sunrise 20 miles off the coast of Washington State sheds light on the challenges ahead for a life-long commercial fisherman.
