It might feel like it was only yesterday that the Curiosity rover touched down on Mars, but in August, the rover celebrated its fifth birthday! For a kindergartener, it's made some really impressive discoveries.

This week on SciShow Space News, photos of Comet 67P and Pluto are helping us solve old mysteries and creating some new ones.

We use algorithms every day for things like image searches, predictive text, and securing sensitive data. Algorithms show up all over nature, too, in places like your immune system and schools of fish, and computer scientists...

In ancient times, wildcats were fierce carnivorous hunters. And unlike dogs, who have undergone centuries of selective breeding, modern cats are genetically very similar to ancient cats. How did these solitary, fierce predators become...

One of the most fundamental ideas in physics is that the disorder of the universe, also known as entropy, is constantly increasing. But, life’s inherent chemical makeup has been hacking the disorder of the universe for billions of years!

How can we begin to understand the way the brain works? The same way we begin to understand a city: by making a map. In this visually stunning talk, Allan Jones shows how his team is mapping which genes are turned on in each tiny region,...

Catnip! Cats roll in it, rub their cheeks on it and paw at it... but what is it about this stuff that gets our feline friends caught up in such a frenzy?

When you think of antihistamines, you're probably only thinking about getting rid of a runny nose, but we're learning that antihistamines can be used for nausea, insomnia, and even depression!

Different dogs look incredibly different - but that doesn't mean they are necessarily more diverse.

Drugs that treat heart failure are also prescribed for anxiety? What's up with that?

The constant thud underneath your feet. The constrained space. The monotony of going nowhere fast. Running on a treadmill can certainly feel like torture, but did you know it was originally used for that very purpose? Conor Heffernan...

SciShow Space takes you to the moon! Learn about the competing theories about how Earth's closest neighbor formed.

The history books are full of mysteries, some of which we're just now getting around to solving.

Paul Andersen shows you how to use Screenflow, Keynote, and Omnidazzle to make an educational screencast.

Scientists were able to get molecular information from 1.7 million years old teeth using a new method that could completely change how we study extinct organisms.

Today we’re going to talk about recommender systems which form the backbone of so much of the content we see online from video recommendations on YouTube and Netflix to ads we see on Facebook, Twitter, and well, everywhere else. We’ll...

There's a lot of talk these days about when and how we might all move to Mars. But what would it actually be like to live there? Mari Foroutan details the features of Mars that are remarkably similar to those of Earth — and those that...

Feathers might have originated tens of millions of years before we'd thought, and a 3D rendering of ankylosaur nasal passages lends new insight into how they stayed cool.

Rodney Mullen is the godfather of street skating, and in this exuberant talk he shares his love of the open skateboarding community. He shows how the unique environments skaters play in drive the creation of new tricks -- fostering...

Sometimes being in a traffic jam can feel like being stuck in a clogged pipe. And it turns out, maybe that feeling isn’t too far off. Today we look at 3 things that are remarkably unlike fluids, yet still behave in liquid-like ways.

The sun is beginning a new weather cycle, causing debate among scientists about how intense things are going to get, and elsewhere, scientists are looking into just how fluid our early universe was.

Scientists conduct some pretty cool research experiments for Mars here on Earth. These terrestrial analogues have revealed some incredible discoveries!

With two new missions set by NASA, we hope to learn so much more of the asteroids surrounding Jupiter's orbit and the origin of our moon!
