Did you know that many of us have up to 4% neanderthal DNA? And that 100% of your DNA may come from outer space? No joke. The biochemistry that defined the coding system of your DNA may have happened off-world, and perhaps even long...

We may have planet-shattering asteroids to thank for the origin of life on Earth.

Where did life come from? It’s one of the biggest questions humans have ever asked — and the answer might be locked in ancient space rocks that were around before life began. To find out, NASA pulled off one of its most ambitious...

Humans may have been around for a long time, but life has existed for way longer. In this episode of Crash Course Biology, we’ll journey through deep time to uncover the history of life on Earth. We’ll explore the big, game-changing...

While Earth’s natural history has been playing out over the last few billion years, another epic planetary saga has also been unfolding right next door.

We’ve probed some 250 kilometers into Jupiter’s atmosphere, and that’s raised some new questions about the mysterious planet. And we’ve taken another important step in looking for life on Mars by using a common chemistry process for the...

Last week, NASA released some pretty cool Mars news: Curiosity found even more evidence to indicate the planet could’ve been habitable billions of years ago.

The IARC has categorized processed meat as a definite carcinogen. But how dangerous is it really? Do we finally have to give up bacon?

Fluorescent molecules are useful for a lot more than just making you look cool at your local rave. Fluorescence turns out to be a kind of chemical superpower that lets us tackle all kinds of problems, from solving crimes to saving lives!

October was bittersweet for space scientists as we said goodbye to both the Kepler Space Telescope and Dawn mission.

You might not want to sign up for the Enceladus Ice Hockey League... And some researchers have an idea that might make the Big Bang model more accurate!

From "superhabitable planets" that can potentially sustain life longer than earth to rogue planets that don't even orbit a star, we’ve talked about some strange places that could host extraterrestrial life over the last few years. Here...

Paul Andersen details the processes of photosynthesis and respiration in this video on free energy capture and storage. Autotrophs use the light reactions and the Calvin cycle to convert energy from the Sun into sugars. Autotrophs and...

SciShow Space News shares the latest developments from around the universe, including the discovery of water vapor on a new “exo-Neptune,” and cyanide found in the clouds where stars are born.

Alkanes are kind of the wallflowers of organic chemistry, but they still have important functions in the world around us. In this episode of Crash Course Organic Chemistry we’re building our knowledge of organic molecules by learning all...

Organic chemistry is pretty much everywhere! In this episode of Crash Course Organic Chemistry, we’re talking about the amazing diversity among organic molecules. We’ll learn about the origins of organic chemistry, how to write Lewis...

Scientists have made a groundbreaking discovery in a galaxy 12 billion light-years away: complex organic molecules, the basic building blocks of life. This finding, glimpsing into the universe's infancy, suggests that the fundamental...

Despite the incredible variations of life we see today, at the fundamental level, all living things contain three elements: Nucleic acids, Proteins, and lipids. These three things had to have been present in order for...

SUMMARY:

To make most complex structures in the universe like trees, and us, you need more than atoms. You need molecules. How do you go from atoms formed in the core of stars, to molecules that can lead to living...

There are 4 main types of carbon-based molecules important to life. They are the building blocks for every living organism on this planet. In this video, I will give you a quick introduction to each type with some fun examples.

Carbon-based molecules are the basis of life as we know it. Molecules like lipids, proteins, nucleic acids, and carbohydrates that make up all living things have one thing in common - carbon.

Or primordial soup, refers to the medium in which the first life on Earth may have originated.
