Want to learn more about the topic in this week's video? Here are some key words/phrases to get your googling started: - Lifting Condensation Level (LCL): The altitude at which the water vapor in rising air begins to condense - Adiabatic...

The world relies on manufacturing, and manufacturing relies on heat — a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use. Energy entrepreneur John O'Donnell has figured out a...

It's a bird, it's a plane, it's a... peach emoji? The Airlander 10 is the world's biggest currently operational aircraft, and though it won't be setting any speed records, it may hold the key to greener, more sustainable commercial and...

Nuclear war is a terrifying existential threat, but we shouldn't only fear the blasts because the ensuing smoke is the real killer.

You might not think of a sea creature as helpful in the prevention of climate change, but sperm whales have been doing their part to cool the planet by doing what most animals do best: pooping.

To restrain global warming, we know we need to drastically reduce pollution. The very next step after that: using both natural and technological solutions to trap as much excess carbon dioxide from the air as possible. Enter Orca, the...

If you want to be prepared for a nuclear attack, here’s a science-based guide to help you get there.

There are a lot of nuclear weapons on Earth, so many that we often say it's enough to "destroy the world several times over." But could we? Well, that depends on what you mean. Also...no matter what you mean, probably not. The Earth is...

SciShow Space News gives you the update of the historic mission that has, for the first time ever, landed a spacecraft on the surface of a comet!

In some cartoons, the one with a bigger brain is often described as "smart," but is it true in real life?

You might not think of a sea creature as helpful in the prevention of climate change, but sperm whales have been doing their part to cool the planet by doing what most animals do best: pooping.

Denial of Service (DOS) or Distributed Denial of Service (DDOS) attacks take down servers by distracting them with meaningless traffic until basically they can't take it any more. The way we talk about the result of a software program...

We could generate a lot of usable energy from human and animal poop through greater adoption of a process for using microbes to break down poop into methane...

Canadian filmmaker Martin Villeneuve talks about "Mars et Avril," the sci-fi spectacular he made with virtually no money over a seven-year stretch. In this charming talk, he explains the various ways he overcame financial and logistical...

Hank eases our minds about the alleged bacon shortage, and informs us of some actual meat shortages we may see the effects of in the coming years.

This video is about the cycloid curves on Jupiter's moon Europa - they're ridges or valleys...

Mister Brown gets a video message from his friend, Ariel Waldman, a real scientist who went all the way to Antarctica to study life that lives under the ice!

Waste not, want not.... right? Poop, in all of its various forms throughout nature, shapes the world in ways you might not imagine. One creature's waste is another's fuel, and all over nature these leftovers help new life spring up....

Hank talks with Owl Research Institute founder Denver Holt. Then Jessi introduces the bird lovers to a pigeon. Warning: watch your ears for wing flapping into the microphone.

The extreme mass of neutron stars leads to enormous gravitational pulls, resulting in nearly perfect spheres. But those imperfections, or mountains, might be able to help us spot more neutron stars in the future! And back on Venus, more...

Blood-suckers may seem like they have it easy, but feeding on blood comes with a lot of challenges.

Because exercise isn't essential for short-term survival, we don't exercise enough, so we need to reincorporate purposeful physical activity into our lives.
