What if we could use the power of DNA to create a sustainable, circular economy? In a talk about breakthrough science, synthetic biologist Jason W. Chin describes his team's work rewriting the genetic blueprint of cells to create a...

Things have been getting more and more complicated here in Crash Course Organic Chemistry, and as we deal with more complex molecules, parts of molecules we don’t want to react will start reacting along with the parts that we do....

In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The...

In this video Paul Andersen explains the final AP Biology practice on connecting knowledge. The video begins with an introduction to interdisciplinary studies and how science is changing over time. He describes differences of scale in...

In this video Paul Andersen explains the importance of intermolecular forces in chemistry. Intermolecular forces exist between dipoles (like hydrogen bonds), between dipoles and induced dipoles (like Ar and HCl) and between induced...

There's a massive cloud in the center of our galaxy, and it's full of alcohol. Party in the Milky Way! But how did it get there? And what does it have to do with the search for life elsewhere in the universe? SciShow Space explains!

This video is about the difference between complexity and entropy, and how complex things like life can arise from disorder. Thanks to Google Making and Science for supporting this series, and to Sean Carroll for...

Dr. Orion Berryman talks with Hank about the cool chemistry going on in his lab, and Jessi from Animal Wonders brings in Prickle the Hedgehog!

Have you ever panicked before a drug test because you just ate a poppy seed muffin? Check out this episode to see if there’s really something to worry about with poppy seeds.

In 1985, scientists discovered that 60 carbon atoms could join up to form one big soccer ball shape: a buckyball! It's a strange little molecule.

And thus begins the most revolutionary biology course in history. Come and learn about covalent, ionic, and hydrogen bonds. What about electron orbitals, the octet rule, and what does it all have to do with a mad man named Gilbert...

This Nobel Prize season, dive into the world of the super small for physics and chemistry. It's where the nanocars roam and phase transitions get really weird.

Scientists have been turning to the animal world for inspiration for a long time, including for medicines. And many different types of animals have been responsible for this inspiration, including sharks, spiders, and... roadkill.

Raindrops and snowflakes generally start to form around something else in the air, like a speck of dust, but sometimes that something else is bacteria.

In this video Michael Aranda explains what the Leidenfrost Effect is, and how it can cause liquid to 'levitate'.

The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let's journey back to the...

In 1990, an experiment conceived by Carl Sagan was performed using using the Galileo spacecraft. The purpose? To detect life on a planet based on measurements by a space probe. The experiment was successful, and abundant life was...

"If you live in the northern hemisphere, there's a decent chance you're in a winter wonderland right now. Settle in with a hot drink for this winter compilation and learn about some of the interesting things that make winter wondrous!

What do astronomers look for when they study exoplanets for signs of alien life? Hank explains how space telescopes are already yielding tantalizing clues of what other worlds might hold -- including water! -- and how the next generation...

Our various secretions - from tears to earwax - can tell us more about our bodies than you might think!

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...

Hank clarifies the misconceptions about Chagus disease, discusses a couple of interesting celestial events - one that happened in the past and one that will happen in the distant future, and sheds more light on the benefits of sexual...
