Astronomers have thought for years that Earth was dry in the beginning, but a new paper suggests that Earth might have actually started out wet! And In other meteorite news, a new study of impact sites might give us new clues about...

As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team's work mass producing electrolyzers...

What we think of as 3D printing, says Joseph DeSimone, is really just 2D printing over and over ... slowly. Onstage at TED2015, he unveils a bold new technique -- inspired, yes, by Terminator 2 -- that's 25 to 100 times faster, and...

In this week's news, scientists announce that they’d made the first entirely computer-generated bacterial genome, and a new surgical procedure that does away with cuts and scars.

A visual for derivatives which generalizes more nicely to topics beyond calculus. Thinking of a function as a transformation, the derivative measure how much that function locally stretches or squishes a given region.

Diamonds are iconic, but some of them might make others a little green with envy.

Last week, the recipients of the 2017 Nobel Prizes were announced. We take a closer look at the winners of the Physiology and Chemistry Awards, whose breakthroughs change the way we study sleep, and allow us to look at microscopic...

Can we create new life out of our digital universe? Craig Venter asks. His answer is "yes" -- and pretty soon. He walks through his latest research and promises that we'll soon be able to build and boot up a synthetic chromosome. NOTE:...

Everyone dies, but what do we do with those bodies? In this episode of SciShow, Hank explores the various options, from mummification to liquefaction, and everything in between.

We don’t know what causes non-hereditary Parkinson's disease, but researchers have recently identified a gene that might help shed some light on those cases. And another paper suggests that the impact we're having on the frequency of...

Even though proteins are fundamental to life, it’s hard to predict what they look like. But two independent groups announced that they’d cracked it, and it’s all thanks to some seriously clever artificial intelligence.

Hydrothermal vents are some of the most extreme environments on the planet. But in 2000, scientists discovered a vent unlike any other, one that spews white smoke and is 10 times older. And some think it may help us understand how all...

We've talked about variables and solving problems. But how do we keep working on a problem if the first solution doesn't fix it? Trials! In this episode of Crash Course Kids, Sabrina shows us how to use Trials to figure out what the...

How many people does it take to make a cup of coffee? For many of us, all it takes is a short walk and a quick pour. But this simple staple is the result of a globe-spanning process whose cost and complexity are far greater than you...

In this video Paul Andersen explains how a spontaneous process may take either the thermodynamically controlled or the kinetic controlled pathway. If the activation energy determines the path taken then the process is under kinetic...

What if we could use brain waves to treat Alzheimer's? Professor and neuroscientist Li-Huei Tsai details a promising new approach to artificially stimulate gamma brain waves using light and sound therapy, to increase connectivity and...

Fairness is one of the quickest ways to lose or gain trust. A lot of times we assume unfair people are incompetent or opportunistic. In this episode, Evelyn chats about how we perceive fairness and what the hurdles are to being "fair" in...

Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the...

How couting in binary can solve the famous tower's of hanoi problem.

Can playing video games make you more productive? Gabe Zichermann shows how games are making kids better problem-solvers, and will make us better at everything from driving to multi-tasking.

Hank shares some developments in cancer research, from new insights into the behavior of zombie cancer cells, to a new method that uses nanotechnology to kill cancer from within.

Bananas! They've got a long trip from harvest to table, and a lot of science goes into keeping them delicious

Today we’re going to discuss how 3D graphics are created and then rendered for a 2D screen. From polygon count and meshes, to lighting and texturing, there are a lot of considerations in building the 3D objects we see in our movies and...

Hank and PhD Candidate Joanna Kreitinger discuss research being performed on dendritic cells in relation to the immune system. Later, Jessi from Animal Wonders joins to show us the emperor scorpions.
