Large clumps of wasps can occasionally be found on the tops of tall structures, and although you probably still don’t want to mess with them, these aren’t angry swarms—they’re actually super chill parties.

Many animals use the same five senses as we do, but these creatures take that beyond the next level.

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...

A marathoner needs a lot of energy to make their long distance treks, and this is no different for migratory birds. But how are these marathon flyers getting that energy from the mud they’re slurping off of beaches along the way?

Hanging out in the trees of Central and South America are some frogs with pretty unusual coloration. Which is to say, parts of them have no color at all. Their bellies are completely see-through!

Most of us don’t really give fish scales a second thought, but for some fish, the scales of others can make for a tasty snack.

The laws of thermodynamics are cornerstones of physics - but one of them is more breakable than it appears. Hosted by: Olivia Gordon

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!

While viruses can be deadly and completely wreak havoc on humanity, they can also sometimes change our world for the better. Join Hank Green for a new episode of SciShow and learn the truth about the viruses that have shaped humanity...

There's a lot we don't understand about autism spectrum disorder, but this week scientists announced that they may have found a link between the disorder and elevated hormone levels.

The Five Stages of Grief show up in media everywhere from The Simpsons to Robot Chicken, but scientists have long been working on better ways to think about grief.

You might have heard that one year in a dog’s life is equivalent to seven in a human’s. But it turns out that the real ratio is both higher AND lower—depending on your dog’s current age.

We here at SciShow know of two things that can help you get through this flu season: a flu shot, and watching this video. Make sure you do both! Hosted by: Hank Green

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.

Scientific discovery often dabbles in the extreme, challenging and exceeding what we think of as "possible." And this year's discoveries were no different! We present to you three scientific discoveries made this year that set out to...

Different fuels create different types of fires, and each one needs to be extinguished using a specific strategy. Do you know which class of extinguisher is needed for different fires? Hosted by: Michael Aranda

This weird-looking creature has been mistaken for a lot of things, including a whale placenta and a sea monster as well as a garbage bag. And less often, it’s recognized for what it is: a jellyfish!

There’s still a lot of work to be done before HIV is cured, but this week scientists reported the second-ever case of full HIV remission in a patient.

Taking photos used to require technical knowledge and time in a lab, but now we have electronic devices in our pockets that do all of the work for us. How do these miracle devices do it? Hosted by: Olivia Gordon

While you might hear the name John Snow and think of dragons and unfruitful endings. There was a real life physician whose efforts saved lives and built the foundation for modern epidemiology.

A new healing gel helped mice regrow brain tissue after a stroke, and scientists suspect someone out there is producing a bunch of ozone-destroying CFCs in defiance of an international agreement! Hosted by: Hank Green

Paleontologists think they've solved part of the mystery of the Cleveland-Lloyd Dinosaur Quarry, a dense bed of Jurassic dinosaur fossils. Also, electron microscope images reveal new, mucus-drenched info about the tubelip wrasse.

3 billion base pairs is a pretty typical genome size for organisms like us, but there are a few plants and animals with genomes so huge they completely blow this number out of the water. Hosted by: Olivia Gordon

The cell nucleus is crucial to multicellular life, so you think science would have a good idea how it evolved. The truth is, we don't, but Scientists do have some theories, including invading giant viruses!
