Although gelatinous animals might seem like simple creatures, they'll probably outlast the rest of us, because being gelatinous might turn out to be the ultimate survival strategy.

I took a trip to Washington D.C. to check out some of our nation's most famous monuments. Where do they come from? From the depths of the Earth to the distant reaches of the cosmos, you'll never look at history the same way again

There are over 13,000 active seismic stations out there, producing far more data than seismologists have time to go through. So, researchers set up a showdown of humans versus machines to sift through all this information and, in the...

Every day, humans literally flush a valuable resource down the toilet: nitrogen. But there are some animals that have figured out a way to recycle the extra nitrogen in their bodies by moving it not to their livers, but to their mouths!

Hank revisits his passion for exploring the Red Planet, breaking down the two biggest challenges of sending humans to Mars: radiation and propulsion. He explains the science behind the obstacles future Mars-bound astronauts will face, as...

With our current understanding of evolutionary history and our strategy of cladistic naming, if we wanted to have both goldfish and sharks under a single group called "fish", then mammals must also be called fish....

Did you know that there were over 200 types of cows? Join Jessi and Squeaks as they discuss some cool facts about these amazing animals.

Some fish have superpowers! Zebrafish eyes can boost the color and contrast of what they see and baby whale fish are electric.

You like space exploration, and we like space exploration. So why aren't we investigating our closest to galactic neighbor, the triple star system Alpha Centauri? Is it time to give interstellar travel a shot? How would we do it? Hank...

I’t teach an old dog new tricks — but that saying might not be as trustworthy as you’d think.

What the astronauts felt when they saw earth from space changed them forever. Author and artist Benjamin Grant aims to provoke this same feeling of overwhelming scale and beauty in each of us through a series of stunning satellite images...

Learn about the history of dudes, and a new theory about deep voices in this new episode of SciShow News. You know, science... bro... stuff.

Bacteria "talk" to each other, sending chemical information to coordinate attacks. What if we could listen to what they were saying? Nanophysicist Fatima AlZahra'a Alatraktchi invented a tool to spy on bacterial chatter and translate...

In which John Green teaches you about globalization, a subject so epic, so, um, global, it requires two videos. In this video, John follows the surprisingly complex path of t-shirt as it criss-crosses the world before coming to rest on...

You may have heard about a study that found pigeons can visually recognize what printed words look like. Does that mean these birds can read?

Some experts feared we were in for a "twindemic" during the 2020-2021 flu season. That didn't happen, which might mean that there will be more people susceptible to getting sick this year.

Humans (and our pets) frequently instinctively stretch as soon as we wake up. But why? What is happening in our bodies when we stretch and yawn to wake ourselves up?

Building a perfect igloo takes cool science!

The edge of everything used to be the edge of the map. But now, thanks to what we know about astrophysics and the universe, the edge of everything might not even exist....

In this short, amazing demo, Fabian Hemmert imagines one future of the mobile phone -- a shape-shifting and weight-shifting handset that "displays" information nonvisually. It's a delightfully intuitive way to communicate.

Lice... the mere mention of them is enough to make most people all itchy. Well, get ready to get scratching, because we've compiled seven squirm-inducing lice facts on this week's List Show!

The paleo diet is becoming more popular, but research suggests its claims aren't all that scientific.

Today, our closest evolutionary relatives, the apes, live only in small pockets of Africa and Asia. But back in the Miocene epoch, apes occupied all of Europe. Why aren't there wild apes in Europe today?
