You probably know about the geomagnetic field that protects the earth from solar storms and radiation. But precision satellites have measured ANOTHER magnetic field coming from Earth, and its signals might hold the key to searching for...

The ocean is the largest ecosystem on Earth, but it's still mostly unexplored. This is partially due to the challenges of ocean exploration, like bone-crushing pressure and the need to bring your own air. But here are five ways that...

Scientists think they’ve discovered some peaks taller than Mt Everest deep beneath the earth’s crust, and this range might be the key to one of the biggest mysteries in geology!

2017 has been an eventful year, so as it comes to a close we'd like to look back at some of its most superlative science.

If you’ve heard anything about pesticides, it’s probably about how toxic they are. But they make growing food more cost-effective, so when some make it into your groceries, how bad can they be?

So what exactly do magnetic fields actually do? What would happen if they went away? Turns out, it could be catastrophic! SciShow will explain it all in this fun new episode hosted by Michael Aranda!

We’ve sent thousands of things into space over the years! Many of them just orbit the Earth, and some are flying out past the edges of the Solar System. In this episode, we present our favorite currently active space probes!

Hank's news this week informs us on a couple of crazy science experiments, updates us on some earlier topics (dangerous asteroids and ancient phallic rock art), and briefs us on a new study that seeks to find the evolutionary origins of...

Hank gets to the bottom of this "faster-than-the-speed-of-light-neutrino" kerfuffle, discusses some ancient stuff, and announces the winner of the award for worst science in a film.

The environmental impact of the foods we eat can be tricky to track. But now, researchers in the UK have developed a system to estimate the impact of 57,000 food products in the UK and Ireland! And we are gaining insights into the...

You can complain about having the longest day ever today, and here is the science to prove it!

Why is good news so rare? In a special broadcast from the TED stage, journalist Angus Hervey sheds light on some of the incredible progress humanity has made across environmental protection, public health and more in the last year,...

In 1815, Mount Tambora erupted and its emissions spread across the globe, blotting out the sun for almost an entire year. This wreaked havoc on agriculture, leading to famines all across the Northern hemisphere. It was the year without...

Is it possible for taking action on climate change to make you feel happy? Behavioral scientist Jiaying Zhao believes that's the only way we'll create lasting, sustainable change. From treat meals to feng shui fridges, she offers eight...

Jessi and Sam the Bat team up to answer your questions about space, like: How was the universe created?

Anthony and Squeaks find out how you can put telescopes in different places to help you see further away and get better pictures of things in space!

If you were looking down at the Earth from space, what would you be able to see? Do you think you would be able to see your house? What if you were super far away?

This week, Mister Brown joins Squeaks to answer a bunch more of your questions about the Earth and about our bodies!

In the early 20th century, Alfred Wegener's theory of Continental Drift laid the foundation for our modern theory of plate tectonics. And today we know something even more exciting: Pangea was only the latest in a long lineage of...

What are the planets outside our solar system like? Astrophysicist and TED Fellow Jessie Christiansen has helped find thousands of them (and counting), and the variety is more wonderful and wild than you might imagine. She shares details...

The best form of energy available to the world is energy reduction. In this video Paul Andersen explains how energy conservation and energy efficiency and be used to decrease energy during peak demand. Tiered and variable pricing, as...

In this video Paul Andersen explains how matter and energy are conserved within the Earth's system. Matter is a closed system and Energy is open to the surroundings. In natural systems steady state is maintained through feedback loops...

Welcome to the Neighborhood! Humans need a lot of things to survive (I'm sure you've noticed). We need food, water, and shelter and it takes a lot of resources to get all of those things. What are resources? In this episode of Crash...

"For all that's ever been said about climate change, we haven't heard nearly enough about the psychological impacts of living in a warming world," says science writer Britt Wray. In this quick talk, she explores how climate change is...
