Your cells are coated with sugars that store information and speak a secret language. What are they trying to tell us? Your blood type, for one -- and, potentially, that you have cancer. Chemical biologist Carolyn Bertozzi researches how...

A world only 2°C warmer, or 3.6°F, would be one that is much different than the world we live in today, but what does that actually look like?

Whales have a surprising and important job, says marine biologist Asha de Vos: these massive creatures are ecosystem engineers, keeping the oceans healthy and stable by ... well, by pooping, for a start. Learn from de Vos, a TED Fellow,...

Blue Origin announced a a new lunar lander, Blue Moon, that will be delivering supplies, and eventually astronauts to the lunar surface within the next 5 years, and robots like Chang’e-4 are giving us an early glimpse at what we might...

As a species, humans tend to have a bit of a fondness for mind altering substances. Is this true of other animals as well?

Mars is covered with the remnants of long-dead volcanoes, but one of them might have been alive surprisingly recently.

In this video Paul Andersen shows conceptual thinking in a mini-lesson on testing causes.

SciShow Space News gives you a whiff of comet 67P, and takes you through a record-breaking skydive from an altitude five times the height of Mount Everest.

Nature is wonderfully abundant, diverse and mysterious -- but biological research today tends to focus on only seven species, including rats, chickens, fruit flies and us. We're studying an astonishingly narrow sliver of life, says...

You might not think of volcanoes as particularly musical, but they do actually generate infrasound! And scientists may be able to use that sound to help predict when a volcano is about to erupt.

Hank delivers news of the future, with his rundown of the top space missions scheduled for 2014. Learn about upcoming launches to a nearby asteroid, a comet as it approaches the sun, and the first test flight of NASA's new Orion crew...

Many animals need sleep. But all of the threats and demands animals face don't just go away when it's time to doze. That's why a range of birds, mammals, and even humans experience some degree of asymmetrical sleep, where parts of the...

The ocean covers 70% of the planet, but humans still don’t know very much about it. In this episode, Hank discusses seven mysterious ocean topics.

You know, it's probably best to just not put snow in your mouth regardless of color.

May 23rd, 1967 could have been the beginning of the end - all thanks to the sun.

It's tricky to study the particles of our Sun because Earth’s magnetic field deflects them, but scientists have found ways to do it! They're helping us understand things like the Sun’s origin, what it's made of, and how it might affect...

Plutonium powered robot car! With a laser gun! That's (kind of) what's hurtling through space right now as part of NASA Mars Science Laboratory heads for the Red Planet. Hank walks you through this historic mission, with the help of some...

Hank gives us the skinny on three plans NASA scientists have come up with to save Earth from an asteroid impact. Hopefully we'll never have to use any of them.

NASA’s Magellan mission gave us unprecedented insight into Venus’s rocky surface, and even now, more than 25 years after the mission ended, it’s still one of our main tools for learning about our mysterious, next-door neighbor.

Humans are fascinated by shiny stuff. Not only do we find these things attractive, but we also tend to perceive them as being high quality. Well, turns out this infatuation may be related to our evolutionary relationship to water.

SciShow Space explores new theories about the timing of the development of life on Earth, and elsewhere in the universe.

Mark Shaw demos Ultra-Ever Dry, a liquid-repellent coating that acts as an astonishingly powerful shield against water and water-based materials. At the nano level, the spray covers a surface with an umbrella of air so that water bounces...

Solar tornadoes are not tornadoes, and scientists are studying a black hole with a telescope bigger than the earth!

We’ve discovered what appears to be the first known moon outside of the solar system and new models of Europa’s surface predict the presence of ice blades!
