Working with a team of physicists, Dr. Deborah Rhodes developed a new tool for tumor detection that's 3 times as effective as traditional mammograms for women with dense breast tissue. The life-saving implications are stunning. So why...

How can cities help save the future? Alex Steffen shows some cool neighborhood-based green projects that expand our access to things we want and need -- while reducing the time we spend in cars.

It's easy to take things at face value in video games. But when we take a deeper dive into the physics in The Legend of Zelda: Majora's Mask, it seems that the "MOON" might be one of those things that isn't quite what it seems. Given its...

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?

The lingerling radiation from the ancient universe still surrounds us to this day.

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!

Earth’s outer shell is made of two materials whose different densities and thicknesses give rise to two distinct “levels” on the planet’s surface.



Watch our new show Paradigms (U.S....

Can you make a black hole out of light? Learn about the strange theoretical object called the 'Kugelblitz'.

It takes light a zippy 8 minutes to reach Earth from the surface of the Sun. But how long does it take that same light to travel from the Sun's core to its surface? Oddly enough, the answer is many thousands of years. Sten Odenwald...

Roughly 85 percent of mass in the universe is "dark matter" -- mysterious material that can't be directly observed but has an immense influence on the cosmos. What exactly is this strange stuff, and what does it have to do with our...

SciShow Space takes you through perhaps the scariest part of every space mission -- re-entry. How do astronauts survive the turbulent return to Earth’s atmosphere? Math, y’all!

There's nothing wrong with having your head in the clouds

There’s one kind of planet we’ve found more often than any other in the universe so far: mini-Neptunes. Now, some scientists think they’ve figured out why there are just so many of them.

Sharks have been celebrated as powerful gods by some native cultures. And today, sharks are recognized as apex predators of the world's ocean. What is it that makes these fish worthy of our ancient legends and so successful in the seas?...

This week in space news, a new makeover for one of the Hubble Telescope's most famous images, and tips on spotting Comet Lovejoy in the night sky.

SciShow Space takes you to a distant, ancient black hole that … really shouldn’t be, and psyches you up for the Dawn spacecraft’s final approach to Ceres!

A dung beetle has a brain the size of a grain of rice, and yet it shows a tremendous amount of intelligence when it comes to rolling its food source -- animal excrement -- home. How? It all comes down to a dance.

NASA is launching a mission to send a probe into the sun, and it's the first to be named after a living scientist: Eugene Parker and the Parker Solar Probe! Astronomers have found another hot topic, and it's the hottest planet we've ever...

How do spacecraft survive the enormous heat and crushing g's of re-entry? And why don't astronauts actually land in rockets, like they do in cartoons and comic books? SciShow Space explains!

Joe Hanson went behind the scenes at the Monterey Bay Aquarium to learn about jellyfish.

The Sun is getting brighter and the planets in our solar system that are habitable are changing.

A forest planted by humans, then left to nature's own devices, typically takes at least 100 years to mature. But what if we could make the process happen ten times faster? In this short talk, eco-entrepreneur (and TED Fellow) Shubhendu...

Most of the universe is made up of dark matter, so could it form into stars and galaxies like regular matter?

Why Does Earth Have Deserts? For the same reason it has Rainforests: Hadley Cells!!!
