Tornadoes are the most violent storms on Earth, with wind velocities that can exceed 200 miles per hour. How do these terrifying cyclones form? Meteorologist James Spann sheds light on the lifespan of tornadoes as they go from supercell...

To hopefully put your mind more at ease, Hank is here to talk about the work that goes into designing and building ICBMs.

Designing skin for robots was out of reach for a long time, but last week, scientists announced they successfully made the first autonomous robot with full-body skin!

In some arid parts of the world, people cool off by drinking hot beverages. Can a hot drink on a hot day really cool you down?

This week scientists invented futuristic technologies that sound made up by Hollywood’s spy movies, and we might be able to have infrared supervision without goggles...soon.

Mercury is the closest planet to the sun. It has no atmosphere and is, as such, covered in craters. It's also incredibly hot but, surprisingly, has water ice hiding beneath its surface.

It requires a certain attitude to brave the elements of Antarctica. Luckily, the Antarctic midge has a set of adaptations that fit the bill.

Most fish are pretty sluggish in the cold. But the Pacific bluefin tuna is one of the fastest apex predators in the frigid Pacific ocean. Their physiology has adapted to help them retain more of the heat their bodies produce, except when...

Chemical plants create many of the materials found in everyday items, from the shoes you wear to the car you drive to the cell phone in your pocket. But the massive carbon footprint from chemical manufacturing is leading to climate...

You need it, you love it, you probably live on it: it's land! But have you ever thought about where land even comes from?

SciShow News explains the latest climate weirdness, and why the Global Warming Hiatus wasn’t really what it sounded like. Plus, see how humans have harnessed the climbing power of the gecko!

What's more exciting than a spaceship? A spaceship on Fiya! NASA plans on playing with fire. Caitlin Hofmeister explains in this episode of SciShow Space!

The sun is obviously a big factor in the earth's weather, but changes in the solar cycle don't always affect our climate in straightforward ways.

We didn't understand how our bodies processed pain until recently. From hot peppers to slamming your hand in a drawer, recent research suggests that pain from various sources can be processed in a surprisingly similar way.

Is it better to walk or run when it's cold out? If you run, then you have to deal with wind, wind chill, etc, but your body generates more heat. If you stay still, standing or walking slowly, you don't generate as much heat, but don't...

You’ve seen dogs pant, but do you know why they do it? And is it true that dogs can’t sweat? Quick Questions has the answers!

These days it seems almost trivial to cool atoms down to near absolute zero temperatures in a lab, but what is the lowest possible naturally occurring air temperature on this planet?

This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it! This video is about how life arose and what its main function or purpose in the...

You might consider humans or beavers to be the best engineers on the planet, but these 5 other animals go to great lengths to put our houses and dams to shame. Chapters SOCIABLE WEAVER 0:38 GREAT BOWERBIRD 2:13 PUFFERFISH 3:39 4 ORIENTAL...

A world only 2°C warmer, or 3.6°F, would be one that is much different than the world we live in today, but what does that actually look like?

Sperm count in Western countries has been dropping for over a hundred years, and scientists have some ideas as to what’s behind this swimmer shortage.

A placebo can only work if someone (or something) believes it will. So how can animals be fooled by the placebo effect?

It's so obvious that it's practically proverbial: you can't unboil an egg. But actually, it turns out that you can -- sort of. Eleanor Nelsen explains the process by which mechanical energy can undo what thermal energy has done.

Hank delivers news of the future, with his rundown of the top space missions scheduled for 2014. Learn about upcoming launches to a nearby asteroid, a comet as it approaches the sun, and the first test flight of NASA's new Orion crew...
