The mammoths fossils found on the Channel Islands off the coast of southern California are much smaller than their relatives found on the mainland. They were so small that they came to be seen as their own species. How did they get...

Back in the late Miocene epoch, there was an island--or maybe a group of islands-- in the Mediterranean Sea that was populated with fantastic giant beasts. It’s a lesson in the very strange, but very real, powers of natural selection.

In 2003, microbiologists made a huge discovery. One that would force us to reconsider a lot of what we thought we knew about the evolution of microbial life: giant viruses.

Teeth are so well preserved in the fossil record that they make the best, most informative fossils we can find, from phylogenetic studies to learning about the evolution of the human brain.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

Do you like drinking milk or chatting with your friends? Well, you can enjoy those because of the evolution happened over the past million years, and we are still evolving. Let's find out what will we be like in the future with us!

In what seems like an inefficient use of resources, these penguins always lay two eggs, but then ignore, discard, or just straight-up destroy the first one. What gives, penguins?

This week's SciShow news has Hank bringing us a primer on the science behind various illegal and illicit ways in which athletes "improve" their bodies, proof of general relativity that we can actually see, and a new way to measure how...

Today's data storage solutions have an expiration date. What's on the horizon to replace them?

There are lots of unsolved mysteries in the world of math, and many of them start off with a deceptively simple premise, like: What's the biggest couch you can slide around a 90-degree corner? Hosted by: Michael Aranda

Sometimes the males and females of a species can look really different from each other. This is pretty common in animals (think peacocks), but there are some plant species out there with extreme sexual dimorphism! And now scientists...

If you want to make particles move really fast, you have to build a particle accelerator that is really big, right? Not anymore! Hosted by: Hank Green

While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do they do that?

The size, shape, and designs of the balls used in sports are usually the results of decades or even centuries of trial and error, and the cute, dimply li'l golf ball is no different!

After visiting Sam the Bat in his family’s cave, Squeaks is learning all about the rock icicles that are growing from the ceiling and the floor in the cave!

Squeaks went on a trip to the beach, and wants to tell Mister Brown all about it! And, we can learn all about the science that formed the beach, plus a guest appearance by Grady the tardigrade to talk all about the plants and animals in...

What is the derivative of a^x? Why is e^x its own derivative? This video shows how to think about the rule for differentiating exponential functions.

Higher dimensional spheres, or hyperspheres, are counter-intuitive and almost impossible to visualize. Mathematician Kelsey Houston-Edwards explains higher dimensional spheres and how recent revelations in sphere packing have exposed...

In this video Paul Andersen explains the differences between a system and an object. Depending on the scale it often times easies to view a system as an object if the constituent parts aren't relevant to the question being asked. He...

An overview of what calculus is all about, with an emphasis on making it seem like something students could discover for themselves. The central example is that of rediscovering the formula for a circle's area, and how this is an...

What exactly are fractals? A common misconception is that they are shapes which look exactly like themselves when you zoom in. In fact, the definition has something to do with the idea of "fractal dimension".

This video is about the Schwarzschild radius of a black hole, (its "event horizon"), and how much mass and density is required to reach the point of no return where an object like a star, neutron star, red giant, etc...
