Our immune systems aren't just critical to our physical health. It turns out they may play a big role in our mental health, as well. And learning more about how these two aspects of our health are interconnected can help us develop more...

In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

Your friendly local weather person says there's a 10% chance it will rain today, so you throw on your flip-flops and head out to enjoy a beautiful day. Next thing you know, you're running through puddles, trying to get out of a...

The Harlem Renaissance was one of the richest, most vibrant, and most culturally generative artistic periods in American history and the work that emerged from that period continues to shape the landscape of American arts and letters...

Wind is an ever increasing source of power worldwide, which means wind farms continue to be constructed. And choosing where to place those farms seems straightforward, but it might not actually be best to place the in the windiest places!

If you stick your finger in a socket, you’re in for a bad time, so how can birds perch on power lines without getting zapped?

When you think about archaeology, space technology probably isn’t the first thing that comes to mind. But from satellites to cosmic rays, archaeologists actually look to space a lot more than you might think!

In this video Paul Andersen explains how the electric field strength decreases as the square of the radius as you move away from a point charge, or a uniform distribution of charge on a sphere. This is a direct application of Coulomb's Law.

With hard work and perseverance, we can change the way we process the world, and if you’ve learned how to read, you’ve successfully re-trained an entire area of your brain!

The sounds of the rainforest include: the chirps of birds, the buzz of cicadas, the banter of gibbons. But in the background is the almost-always present sound of a chainsaw, from illegal loggers. Engineer Topher White shares a simple,...

Two proofs for the surface area of a sphere

Find out why more species live near the equator!

In this video Paul Andersen defines adaptations and explains how organisms can become better adapted to their surroundings using the process of natural selection. Specific examples of adaptations, like coat color in rock pocket mice, as...

We all know that warm air rises, but how does this scientific fact influence our weather and create those flows of air molecules that we know of as wind? In this episode of SciShow, Hank explains where wind comes from, what factors...

Waves are cool. The more we learn about waves, the more we learn about a lot of things in physics. Everything from earthquakes to music! Ropes can tell us a lot about how traveling waves work so, in this episode of Crash Course Physics,...

Paul Andersen explains how eukaryotic cells use compartmentalization to increase the surface area and level of specialization within the cell. Prokaryotic and eukaryotic cells are compared and contrasted. The role of both the mitochodria...

SciShow Space shares the latest developments from around the universe, including news about the first material ever collected from outside the solar system, and a backyard astronomers’ guide to two upcoming planetary conjunctions.

Today we’re going to explain how exchangers...exchange heat. We’ll look at concentric tubes, finned tubes, plate heat exchangers, and shell-and-tube heat exchangers. And we’ll look at some equations to help us sort through heat transfer...

Sophie Howe is the world's only future generations commissioner, a new kind of government official tasked with advocating for the interests of generations to come and holding public institutions accountable for delivering long-term...

Jane Goodall hasn't found the missing link, but she's come closer than nearly anyone else. The primatologist says the only real difference between humans and chimps is our sophisticated language. She urges us to start using it to change...

There's basically a hole in the universe -- a region where there's much less matter than there should be. And we don't know why it's there.

Around the world, there are lakes that disappear without warning. Then, even stranger, they come back! This can happen for lots of different reasons, and the fact that they vanish and reappear reveals some surprising connections.

In this video Paul Andersen explains how land is developed for human use. Urbanization has occurred through the last century as people have moved to cities in large numbers. Transportation and the arrival of the car have led to urban...

India and China have so many people today because they’re good for farming and big, but they’ve always been that way, so they’ve actually had a huge proportion of Earth’s people for thousands of years.
