Meet the "Row-bot," a robot that cleans up pollution and generates the electricity needed to power itself by swallowing dirty water. Roboticist Jonathan Rossiter explains how this special swimming machine, which uses a microbial fuel...

Being able to use human feces as fertilizer could be really helpful for human colonies on other planets. It could also be useful for human colonies on THIS planet! And who doesn’t love recycling!?

It's all about the SUPER TINY in this episode of Crash Course: History of Science. In it, Hank Green talks about germ theory, John Snow (the other one), pasteurization, and why following our senses isn't always the worst idea.

Bees are quite beneficial little critters: pollinating flowers, making honey, and also...helping corpses decompose.

People who live near the equator use more spices per recipe than people who live far from the equator. But that isn't for the reason you think. Spices and other plant ingredients have special powers that make them a truly magical superfood!

SciShow takes you inside the site of the world's worst nuclear disaster to show you how, nearly 30 years later, life has adapted and persisted.

There's a lake so deadly that anything that goes for a swim gets pickled. Yet there's a thriving ecosystem literally living on the edge, which might give astrobiologists a hint at how life could thrive on other worlds.

Each day, the animal kingdom produces roughly enough poop to match the volume of water pouring over Victoria Falls. So why isn't the planet covered in the stuff? You can thank the humble dung beetle for eating up the excess. Eleanor...

In 2010, 30 billion dollars worth of fruits and vegetables were wasted by American retailers and shoppers, in part because of cosmetic problems and perceived spoilage. But what are these spots, anyway, and are they okay to eat? Elizabeth...

Some science to go along with that board of cheese at the party.

You may not realize it, but your body is like a fortress, designed to defend you from tiny foreign invaders known as pathogens. This seemingly small world is actually super diverse, and sometimes super dangerous too. That’s why in this...

Do you really need a daily shower to stay clean, or is it doing more harm than good? Some scientists have recommendations based on what we know about our skin , and what might be living on top of it.

Forests don't have to be far-flung nature reserves, isolated from human life. Instead, we can grow them right where we are -- even in cities. eco-entrepreneur and TED Fellow Shubhendu Sharma grows ultra-dense, biodiverse mini-forests of...

You know about fossils, but what other secrets are lurking in the ground beneath our feet?

While we have long known about the existence of microbes - the tiny bacteria, fungi and archaea that live all around, on and in us - our full relationship has become one of the hottest topics for research only in recent years. That's the...

The microcosmos is home to many unusual partnerships. Life is, after all, just relationships, each of which build upon one another like strokes of paint in an epic tableau of ecology, epidemics, and yogurt?

One thing we’ve heard from many of you is that this show is your sleep show, that soothing bit of media you put on when you need to slow down your brain and drift off. We take that as a huge compliment. It’s nice to know we can be a...
