Remember the last time you used your phone and it left a nice warm spot on your face? - Is that causing cancer? Michael Aranda tells you all about the radiation on your cell phone.

It turns out that "nothing" is one of the most interesting somethings in all of physics.

Though the common ancestor of all modern birds could fly, many different bird species have independently lost their flight. Flight can have incredible benefits, especially for escaping predators, hunting and traveling long distances. But...

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...

A look at what turbulence is (in fluid flow), and a result by Kolmogorov regarding the energy cascade of turbulence.

Africa needs new energy sources to fuel its development, but the continent should invest in renewable energy instead of cheap, polluting alternatives like coal, says climate inclusion activist Chibeze Ezekiel. He tells the story of how...

In this video Paul Andersen explains how mass can be converted to energy and energy can be converted to mass. The equation E=mc2 can be used to determine the amount of energy released from nuclear processes.

Right at the beginning of the Paleozoic, there was a huge explosion of more complex life. And that’s when things started to get really interesting. This is our second installment on the history of life, but you can watch in any order you...

Imagine a distant future when humans reach beyond Earth, forge cities on planets thousands of light-years away, and maintain a galactic web of trade and transport. What would it take to make that leap? And where would we get enough...

So, the stars made the elements, we're all made of star stuff, etc. But what does all this mean? This week Emily Graslie teaches you how the formation of chemical elements in the bellies of the earliest stars made life as we know it...

This video is about how to create muons in a particle accelerator via bombardment of heavy nuclei with protons, which results in creation of charged pions (plus and minus). The pions then decay into muons and mu neutrinos, and...

Alternative energy is great, but our infrastructure isn't exactly equipped to handle it. So scientists are coming up with other ways to use it, including turning it into food.

SciShow takes you on a tour of Canada's Bay of Fundy, home of the largest tidal range in the world.

A look at what turbulence is (in fluid flow), and a result by Kolmogorov regarding the energy cascade of turbulence.

Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80° Celsius, the Sahara Desert receives about 22 million terawatt hours of energy from the Sun every year. That's well over 100 times...

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...

This video is about the original cold fusion: μ muon-catalyzed cold fusion of deuterium, tritium, hydrogen, into helium-3 and helium 4. The problems with it are the half-life of muons and the sticking of muons to alpha...

When you think of a frozen object in space, you might think of Pluto, but stars themselves actually freeze.

In 1986, a prospecting crew in southern Romania was looking for a good place to build a geothermal power plant, when they accidentally discovered one of the oddest caves of all...

In which Hank and John Green teach you about life on Earth. They won't be giving advice on how life should be lived, because this is a history series. Instead, they'll teach you about the earliest forms of life on Earth, and some of the...

Paul Andersen explains how variation is created within a cell. He starts by showing how molecular variation can increase fitness at the local level. He explains how an additional chlorophyll molecule allows plants to absorb more light...

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

This video is about using particle accelerators as part of the solar panel silicon wafer manufacturing process. The accelerators embed protons into the wafer crystals, allowing them to break and separate from the main crystal in...
