You might have heard about animals behaving oddly right before an earthquake hits. But are these reports more than just anecdotes?

Wave power hasn’t yet made a splash because it’s hard to use waves to spin turbines, and because the sea is a harsh place to build things. ___________________________________________ To learn more, start your googling with these...

The US economy has been expanding wildly for two centuries. Are we witnessing the end of growth? Economist Robert Gordon lays out 4 reasons US growth may be slowing, detailing factors like epidemic debt and growing inequality, which...

Some fish have superpowers! Zebrafish eyes can boost the color and contrast of what they see and baby whale fish are electric.

Even though they power many of our modern conveniences, batteries have a long history. Hank explains how and why these marvels work and what they've been used for over the past 2,000 years!

Having the ability to dim your lights seems like a pretty simple thing, but modern dimmer switches work in a surprisingly cool way!

Neuroscientist Greg Gage takes sophisticated equipment used to study the brain out of graduate-level labs and brings them to middle- and high-school classrooms (and, sometimes, to the TED stage.) Prepare to be amazed as he hooks up the...

Our planet has a carbon problem -- if we don't start removing carbon dioxide from the atmosphere, we'll grow hotter, faster. Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical...

We're not in a clean energy revolution; we're in a clean energy crisis, says climate policy expert Michael Shellenberger. His surprising solution: nuclear. In this passionate talk, he explains why it's time to overcome longstanding fears...

Units are a major way we describe the world around us, and by looking at the scientists some of them are named after, we can get a sense of how we’ve learned so much about our universe.

As 18th-century science and medicine brought properties of electricity to light, some Victorian doctors decided that putting sick people in a bathtub and shocking them might be a good idea.

Next stop on our tour of engineering’s major fields: electrical engineering. In this episode we’ll explore the history of telecommunications, electric power and lighting, and computers. We’ll introduce topics like magnetism, electrical...

Wind is an ever increasing source of power worldwide, which means wind farms continue to be constructed. And choosing where to place those farms seems straightforward, but it might not actually be best to place the in the windiest places!

Apparently some species of spiders can fly… and it turns out they don’t even need the wind to do it.

Hank pays tribute to some of the great scientific minds we lost in 2012, and then apologizes for some mistakes made in recent SciShow episodes.

If you stick your finger in a socket, you’re in for a bad time, so how can birds perch on power lines without getting zapped?

You know metal can get really hot, and you probably know that it can melt. But can it burn? Hank shows you how you can burn a hunk of metal like you're some kinda superhero (just be careful, please), and he explains how, in chemistry,...

Ever wonder how your finger can magically control your smartphone screen? We explain in this episode of SciShow.

Despite the rise of renewable energy, the backbone of the power grid is fossil fuels. Adapting the grid to green energy sources is more complicated than flipping a switch.

Given that Earth’s magnetic field helps protect its life-sustaining atmosphere, you might think that the stronger a planet’s magnetic field, the better. But as it turns out, some planets’ relationships with their magnetic fields are a...

There are 118 elements on the periodic table, but it seems like only a handful of them get any attention. But just because you haven't heard of an element doesn't mean that it isn't a vital part of everyday life.

Thermometers might seem like a basic instrument, but science would not be the same without them, and they helped us understand one of the most important ideas in all of science: the conservation of energy.

It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...

India has a historic opportunity to power its industrialization with clean energy -- and its energy choices will make or break the world's fight against climate change, says clean energy executive, physicist and author Varun Sivaram....
