The Grand Canyon is super-wide and super-deep, which might make you think that the Colorado River, which carved it, is particularly old or powerful. Or at least that's what I thought.

It seems wild that some animals basically trade in their bodies for new ones during their lifetime, but it's actually really common – and it makes a lot of sense.

Many crustaceans from all sorts of starting points evolve to end up looking similar, likely due to outside pressures. That’s sort of like what happens with YouTube videos.

We've long known that animal pollination is an important way plants reproduce on land, but we're only just finding out animals also pollinate plants underwater.

The average human, in theory, eats 3 spiders a year. If you're not eating them and I'm not eating them, who is?

A world without predators. It sounds like a safer, happier world, but come on, this is science…

Most living things on Earth need oxygen to survive, but scientists discovered a species of bacteria that uses oxygen totally differently from every other organism on Earth.

Premature babies majorly benefit from skin-to-skin contact with a parent –also known as “kangaroo care”– because it reduces infections and hypothermia and increases weight gain and parental involvement.

The ancestors of gars, horseshoe crabs and coelacanths looked almost the same as their modern relatives. Darwin called species like these “living fossils'' because they seem like they are evolutionarily frozen in time. But Darwin was wrong.

Venezuela’s Lake Maracaibo is home to a legendary lightning storm that has been going on for over 500 years.

You might think the most dangerous thing that can happen at a beach is a shark attack, or that the scariest thing might be a tsunami - but instead, rip currents kill more beachgoers than all other causes combined.

As the waters warm in the deep sea around Antarctica, ecosystem-crushing crabs are able to live closer and closer to the continent.

Life in Antarctica's ocean has followed a completely different evolutionary path from other ocean life because of how cold and isolated the ocean is.

When we say a meme goes “viral,” we aren't actually saying it's making people sick. But the math behind a meme’s spread suggests it's actually a pretty spot-on analogy.

Despite the seemingly basic things we don't know about dinosaurs, we do know some surprising things – like their body temperatures.

Because of the way digestion works, human poop not only contains dangerous microbes, it also contains a wide variety of other things, many of which we could potentially put to use.

There are huge varieties of birth control methods because there are lots of different ways to disrupt the process of sperm-egg fertilization.

Plants can tell when competitors are nearby because they can see them.

We are in the Golden Age of Solar Eclipses, but only for the moment. In fact, I'd argue we're already past peak solar eclipse and it's all downhill from here.

The moon orbits the earth once per month, which means the moon is on the sun side of the earth every month. So... "why aren't there eclipses every month?" is a question we will answer in this video!

Solar eclipses don't just happen here on earth - moons of other planets also pass between those planets and the sun, resulting in various types of solar eclipses on Mars, Jupiter, Saturn, Uranus, Neptune, and even non-planets like Pluto,...

The sun rises in the east, the moon rises in the east, and the stars rise in the east... but solar eclipses, oddly, come from the west. If total eclipses are caused by the sun and the moon, why don't they behave like the sun and the moon?

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

Solar eclipses can happen anywhere on earth, but if you want to see a total eclipse, you need to go to the far north, because the Earth’s shape and orbit determine the high latitudes and eclipse hotspot.
