Making a faster plane takes more than building better engines and structures. To go supersonic, engineers had to solve hundreds of problems -- including ditching one of the biggest assumptions in aerodynamics!

Hank tells us the stories of three experiments in biology that, with creativity and luck, changed science & the world with it in their work to solve the mysteries of the universe.

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

We know these glaciers are already on the way out, so we need to find out whether we can bulk them back up again. For that, we turn to the glaciers’ past – and a lot of penguin bones.

Potato spindle tuber disease wasn't a life-or-death situation, but it led to the discovery of viroids: infectious, replicating bits of RNA

A true "Renaissance Man", inventor, artist & scholar Leonardo da Vinci was one of the most diversely talented individuals of all time. His "unquenchable curiosity" led him to make discoveries and inventions that were beyond his time, not...

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.

Two YouTube musicians battle it out to see who shall sing a song of victory.

Featuring Emily of The Brain Scoop ( / thebrainscoop ) and Cas the Arctic Fox! We decided it would be cool to have guests come into the studio and talk about science with Hank.

Hank interviews Administrator Gina McCarthy of the United States Environmental Protection Agency. They discuss getting people to care about climate change, the EPA's goals going into the United Nations Climate Change Conference, and the...

Can scientists actually make discoveries by licking things? Believe it or not, they can. Join Hank Green and learn the surprising amount of discoveries made by scientists....and their tongues.

A lot of robots are developed to physically replicate our actions and behavior, like a bipedal, balanced walk, a large range of motion, and the ability to perceive and interact with the environment. But, maybe not to your surprise,...

It's taken the work of many programmers to turn computers into something we carry in our pockets, and here are five (technically 10!) that we think you should be aware of.

What is the science behind doppelgängers? In this fun episode of SciShow, two bespectacled science YouTubers enter, one bespectacled science YouTuber leaves ... because while they may look suspiciously alike, Joe Hanson has his own...

Looking at a map, you would never know that North America once almost ripped itself in half. But 1.1 billion years ago, it tried to - and had it succeeded, there would now be an ocean where Lake Superior is!

The toughest, most dominant canine gets the resources and respect - or at least that's the idea that caught on culturally. Turns out, that's not necessarily how it works.

The Internet is older than you might think!

The equator is a clear and accurate line around Earth that makes measuring latitude a precise science, but when it came to figuring out how to do that with longitude, British sailors were at a loss. Until they devised a competition....

Long before we had cameras scientists still needed visual documentation—enter the science illustrator!

The group of bacteria known as Chlamydiae doesn't do much to endear itself to us since these bacteria can cause a variety of illnesses. But it turns out that we may have Chlamydiae to thank for life as we know it!

Science, while often the result of a stroke of genius, can just as easily be a stroke of extraordinarily good luck. Mendel’s work just happened to be a mix of the two.

This week, researches published a genetic analysis of the 11,500-year-old remains of a baby found in Alaska, near where the first Americans crossed the Bering land bridge. That analysis has answered some lingering questions about human...

Hank brings us some late-breaking news from the genus Homo - a team of scientists has sequenced the genome of the Denisova hominin, the latest member to be added to the human family tree.

Indigo may be a very vague and unnecessary color, but it has an interesting history that involves some plants, turmoil, and Isaac Newton's interest in the number seven. Hosted by: Hank Green
