To save the achoque -- an exotic (and adorable) salamander found in a lake in northern Mexico -- scientists teamed up with an unexpected research partner: a group of nuns called the Sisters of the Immaculate Health. In this delightful...

"We will start inhabiting outer space," says Angelo Vermeulen, crew commander of a NASA-funded Mars simulation. "It might take 50 years or it might take 500 years, but it's going to happen." In this charming talk, the TED Senior Fellow...

Hank breaks the news to you about your brain on football, the reality behind the latest moon-base plan, and an epic win -- and fail -- in the animal kingdom.

Paul Andersen describes how cell communication is used in both single-celled and multicellular organisms. He starts by describing the symbiotic relationship between the bobtail squid and the bacteria Vibrio fisheri. He explains how...

Gene-editing tools like CRISPR enable us to program life at its most fundamental level. But this raises some pressing questions: If we can generate new species from scratch, what should we build? Should we redesign humanity as we know...

Sometimes, species end up in places we wouldn't expect, like when the same or very similar species end up on opposite parts of the globe. It's called disjunct distribution, and here are 6 ways that it can happen.

This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it!

What do beavers, termites, and prairie dogs have in common? They all change their environments! Last time we talked about how humans change their environments, but humans are animals and all animals change their environments just by...

Elon Musk's SpaceX program proposes that 100 people could be sent to colonize Mars within 10 years. What might that colony look like?

The story of sloths is one of astounding ecological variability, with some foraging in the seas, others living underground, and others still hiding from predators in towering cliffs. So why are their only living relatives in the trees?

For upside-down mirrors, super hot volcanic chimneys, and neon rocks with living microorganisms, look no further than the Guaymas Basin in the Gulf of California.

In this video Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are...

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...

Navigating territorial hippos and active minefields, TED Fellow Steve Boyes and a team of scientists have been traveling through the Okavango Delta, Africa's largest remaining wetland wilderness, to explore and protect this near-pristine...

We’ve done a surprising amount of exploration on Mars, from its atmosphere, to its surface, and miles deep into its canyons. But mapping its insides has been a quandary that we hadn’t been able to solve until last week!

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

Technology is advancing in leaps and bounds -- and so is economic inequality, says writer Chrystia Freeland. In an impassioned talk, she charts the rise of a new class of plutocrats (those who are extremely powerful because they are...

During the 2017 Project For Awesome livestream, I promised I'd make a tuatara video if we hit our fundraising goal, and I'm a man of my word! Little did I know I'd get to meet a tuatara and learn things about a 200 million year old...

This week on SciShow Space News, we’re learning more about the side effects of space travel… from mice. Plus, we explore the most luminous galaxy!

Baratunde Thurston explores the phenomenon of white Americans calling the police on black Americans who have committed the crimes of ... eating, walking or generally "living while black." In this profound, thought-provoking and often...
