Just how long could you survive on the surface of Mars without a spacesuit? Find out what it'd be like to stand on the surface of Mars, if you forgot to pack properly.

A silly poem encapsulating the ideas from the video about Euler's formula through graph theory.

In this video Paul Andersen explains the wave-particle duality discovered by scientists. In certain situations particles (like electrons and photons) display wave like properties. This phenomenon can best be explored using the double...

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.

Paul MacCready -- aircraft designer, environmentalist, and lifelong lover of flight -- talks about his long career.

Emily Graslie of the Brain Scoop is back again with some more skulls to stump Hank, and Jessi from Animal Wonders brings in Blueberry the blue-tongued skink.

Are insects the key to brain-inspired computing? Neuroscientist Frances S. Chance thinks so. In this buzzy talk, she shares examples of the incredible capabilities of insects -- like the dragonfly's deadly accurate hunting skills and the...

Today, cosmic rays are used to understand things like supernovas, but in the early 1900s, they helped us discover brand-new subatomic particles long before the first accelerators.

Scientists are working to develop personalized cancer treatments, but one obstacle in the way is figuring out how different cells react to one another.

Mathematics explains the workings of the universe, from particle physics to engineering and economics. Math is even closely related to music, and their common ground has something to do with a Rubik's Cube puzzle. Michael Staff explains...

Hank addresses a highly requested topic - liquid fluoride thorium reactors - and tells us how LFTR might be the future of energy in ... China?

Every 13 or 17 years, billions of cicadas emerge from the ground to molt, mate and die. Adult cicadas only live a few weeks above ground, but you'd be hard pressed to ignore them -- they are extremely loud! Rose Eveleth explains...

Two long-time SciComm powerhouses face off to find out if either of them retained any relevant random facts from the many, many videos they’ve each produced.

At Serious Play 2008, astrophysicist George Smoot shows stunning new images from deep-space surveys, and prods us to ponder how the cosmos -- with its giant webs of dark matter and mysterious gaping voids -- got built this way.

Hank tells us three things we probably didn't know about the Voyager 1 spacecraft.

Let's admit it: aerial photo drones and UAVs are a little creepy, and they come with big regulatory and safety problems. But aerial photos can be a powerful way of telling the truth about the world: the size of a protest, the spread of...

The amount of metal some special plants are able to take up from the soil would be toxic enough to an average plant to kill it several times over.

Over the next few episodes we're going to talk about the history of video games. Today, we're going to start with the first re-programmable computers in the 1940's. Now, these computers were serious tools. They were for codebreaking and...

Caroline Phillips cranks out tunes on a seldom-heard folk instrument: the hurdy-gurdy, a.k.a. the wheel fiddle. A searching, Basque melody follows her fun lesson on its unique anatomy and 1,000-year history.

Jia Jiang adventures boldly into a territory so many of us fear: rejection. By seeking out rejection for 100 days -- from asking a stranger to borrow $100 to requesting a "burger refill" at a restaurant -- Jiang desensitized himself to...

Hank talks about a few - maybe crazy, maybe reasonable - geoengineering schemes that some scientists have come up with in order to "fix" climate change, including designer clouds, ocean fertilization, and stratospheric shading with...

Artist Dianna Cohen shares some tough truths about plastic pollution in the ocean and in our lives -- and some thoughts on how to free ourselves from the plastic gyre.

Engineering student Péter Fankhauser demonstrates Rezero, a robot that balances on a ball. Designed and built by students, Rezero is the first ballbot made to move quickly and gracefully -- and even dance. (Could the Star Wars sphere...
