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.

Sure, you can point to the geographic north pole on a globe. But getting there, even with fancy equipment like GPS, isn't so straightforward. So scientists are looking into a navigation tool some animals use naturally.

Because eclipses are powerful and frightening events, ancient cultures went to great lengths to understand eclipses, leading to remarkably accurate predictions and helping invent the science of astronomy.

Join Squeaks as he learns about some of the most colorful animals ever: poison dart frogs! Some animals are bright and colorful to warn other animals that they might be dangerous... and some are just...

As the 19th century came to a close, physicists were feeling pretty satisfied with the state of their science. The great edifice of physical theory seemed complete. A few minor experiments remained to verify everything. Little did those...

The double slit experiment radically changed the way we understand reality. Find out what the ramifications of this experiment were and how we can use it to better comprehend our universe.

Our bodies are mirror images of lobsters and other arthropods from back to belly. We've know since the early 19th century that our guts and nervous systems are inverted from theirs, but only recently has molecular biology shown us why....

In the race to survive, both predators and prey use visual tricks to get ahead. One nearly universal trick is countershading, a color pattern that helps animals erase their own shadows or blend into different backgrounds. It’s worked...

How do zebras get their stripes? How do leopards get their spots? And how do giraffes get their giraffe-shaped thingies, whatever they are called? Would you believe the answer is… math? This is the story of a WWII wartime codebreaker and...

What can we make of a design that shows up over and over in disparate cultures throughout history? Theorist Terry Moore explores "Penrose tiling" -- two shapes that fit together in infinite combinations without ever repeating -- and...

Hank introduces us to the most beautiful numbers in nature - the Fibonacci sequence.

Sleep is complicated. And there's still a lot we don't know about it, but zebrafish larvae are a surprisingly good place to look to learn more about what makes us sleepy.

Hank gets to the bottom of two studies reporting high sea ice coverage and snowmass in Antarctica in the same year that the Arctic has reported a record low of sea ice. What is going on here?

Plenty of animals have tears that moisturize their eyes. But does that mean they’re sad? Quick Questions explains!

Climate change is causing wildfire season to get worse every year. And our models of wildfires can't keep up with the things fires can do... like spawn devastating fire tornadoes.

Michael Aranda explores the purpose of zebra stripes.

Almost every human has told a lie at some point or another - but did you know that we are not the only species to do this? From dogs to cuttlefish to thornbills, these 7 animals also lie!

In which Hank celebrates the landing of the Mars Curiosity Rover, which, if you were following SciShow on Twitter, you know was pretty freaking cool. So here are the Top Five Coolest Things about the Mars Curiosity Rover!

Today on SciShow News we talk about a new research effort that is aiming to revolutionize how we treat disease. We also discuss the video where Boston Dynamics shows off it's new version of the Atlas robot by using a hockey stick to mess...

If you want to make a better hip replacement, who better to turn to than… a snake? While these hip-less creatures might seem like a weird choice for help with this particular issue, a major part of creating comfortable, long-lasting...

How is it that you can be looking at a distinct object in front of you, yet picture something entirely different in your mind? The inner workings of what’s happening in our brains to allow this is a puzzle that scientists are now...
