Humans eat a lot of different animals, but almost none of them are carnivores - why?

Australia will perpetually encounter the season opposite to the one we in the northern hemisphere will encounter, so does this means that Australia will never get a white Christmas?

Before the start of the Eocene Epoch about 56 million years ago--Antarctica was still joined to both Australia and South America. And it turns out that a lot of what we recognize about the southern hemisphere can be traced back to that...

Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

When we scan the heavens with giant telescopes we see galactic cannibalism everywhere. We see moments that appear frozen on the human timescale, but are really snapshots of the incredibly violent process of galaxy formation. This is how...

You'd think that the Northern and Southern Hemispheres would be basically symmetrical -- that since our planet is a ball, the climate, temperature, and weather patterns would be the same on top as on the bottom. But there are some...

Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

Scientists are discovering new species at the bottom of the ocean and deep in the rainforest, but there are also plenty of new animals being discovered in cities around the world!

There's an invisible force shaping our lives, affecting the weather, climate, land, economy, and just whether a flag looks majestic or not - we're talking about the wind! Today we’re going to go into the science of where the wind comes...

Today, we're going to talk about how the Earth moves, but to do that, we're going to have to go way back to the early days of the galaxy! Processes that happened before the Earth even formed have led us to the geographic patterns and...

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.

Australia will perpetually encounter the season opposite to the one we in the northern hemisphere will encounter, so does this means that Australia will never get a white Christmas?

Mars Express, one of the longest-running planetary probes ever made, was only intended to last for about two Earth years, but it's still going at 17! And it's taught us an unbelievable amount, including everything from studying its...

Earlier this month, a Chinese moon rover discovered a mysterious glittery substance at the bottom of a lunar crater. How did it get there? Also, Comet NEOWISE takes thousands of years to circle the Sun, and right now we can see it in our...

When astronomers study the universe, they’re often using telescopes that cost millions or even billions of dollars to build. Luckily for the rest of us, there are still plenty of incredible things to see in the sky with the more...

Planetary scientist Joel Levine shows some intriguing -- and puzzling -- new discoveries about Mars: craters full of ice, traces of ancient oceans, and compelling hints at the presence, sometime in the past, of life. He makes the case...

Most rocky planets have pretty consistent surface features, with a fairly even mix of mountains and basins in each hemisphere. This is NOT the case on Mars! What do scientists know about this mystery?

We're living in a brief window of time where our planet isn't frozen underneath a giant layer of glaciers. How much longer will the moderate climate that we've come to know as "normal" continue? This episode looks at how the changes in...

Dive into the science of ocean currents (including the Global Conveyor Belt current), and find out how climate change affects them. -- In 1992, a cargo ship carrying bath toys got caught in a storm. Shipping containers washed...

Today, we're going to take a closer look at how the oceans circulate by following the life of a discarded water bottle as it gets snagged in the North Pacific Garbage Patch. We'll talk about what causes the movement of water, called...

Scientists are discovering new species at the bottom of the ocean and deep in the rainforest, but there are also plenty of new animals being discovered in cities around the world!

Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

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

In this video Paul Andersen explains how the atmosphere surrounds the planet. The state of the atmosphere is climate and is affected by unequal heating, the Coriolis Effect, and the ocean. Convection cells and ENSO are discussed in...
