In the coming years, artificial intelligence is probably going to change your life— and likely the entire world. But people have a hard time agreeing on exactly how AI will affect our society. Can we build AI systems that help us fix the...

Discover the science of how viruses can jump from one species to another and the deadly epidemics that can result from these pathogens. -- At a Maryland country fair in 2017, farmers reported feverish hogs with inflamed eyes and...

Do animals think? It's a question that has intrigued scientists for thousands of years, inspiring them to come up with different methods and criteria to measure the intelligence of animals. Bryan B Rasmussen navigates through this...

What do you get when you combine the strongest materials from the plant world with the most elastic ones from the insect kingdom? Super-performing materials that might transform ... everything. Nanobiotechnologist Oded Shoseyov walks us...

Two thirds of the population believes a myth that has been propagated for over a century: that we use only 10% of our brains. Hardly! Our neuron-dense brains have evolved to use the least amount of energy while carrying the most...

If we hope to someday live on other worlds we need to figure out where we’re gonna lay our heads at “night.” But who would have thought we could use our own bodies as ingredients for our homes?!

In this episode we looked at robots and the engineering principles of robots. We learned how robots use sensors to interpret their environment, how actuators and effectors allow a robot to manipulate the objects around it to accomplish a...

In order to truly understand differences among animal lifespans, we need to stop thinking about a specific number and start thinking about a distribution.

Some of the animals you think of as just cute grass-eating creatures might actually be more interested in chomping on your meaty bones.

Mirror neurons are a very cool part of our brains but some people are taking it way further by making claims that they are responsible for telepathy and ESP. It goes without saying that this isn’t true, but what exactly do mirror neurons...

Seventy thousand years ago, our human ancestors were insignificant animals, just minding their own business in a corner of Africa with all the other animals. But now, few would disagree that humans dominate planet Earth; we've spread to...

So we've talked a lot in this series about how computers fetch and display data, but how do they make decisions on this data? From spam filters and self-driving cars, to cutting edge medical diagnosis and real-time language translation,...

Also known as cercarial dermatitis, swimmer’s itch is more than just an annoying rash…

Over the course of her fearless career, extreme action specialist Elizabeth Streb has pushed the limits of the human body. She's jumped through broken glass, toppled from great heights and built gizmos to provide a boost along the way....

Your body is made of cells -- but how does a single cell know to become part of your nose, instead of your toes? The answer is in your body's instruction book: DNA. Joe Hanson compares DNA to detailed manual for building a person out of...

Our immune systems are generally pretty great, but sometimes they can turn on us. And for some reason, these autoimmune conditions mostly affect women.

Technology is evolving us, says Amber Case, as we become a screen-staring, button-clicking new version of homo sapiens. We now rely on "external brains" (cell phones and computers) to communicate, remember, even live out secondary lives....

It sounds like science fiction, but journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. In this provocative talk, Petranek makes the case that humans will become a spacefaring species and describes...

It might sound like a concept from science fiction, but artificial intelligence is already facilitating the development process behind some pharmaceuticals.

From the microbes in our stomachs to the ones on our teeth, we are homes to millions of unique and diverse communities which help our bodies function. Jessica Green and Karen Guillemin emphasize the importance of understanding the many...

Hank gets into the dirty details behind our lying ways - how such behavior evolved, how pathological liars are different from the rest of us, and how scientists are getting better at spotting lies in many situations.

Louise Leakey asks, "Who are we?" The question takes her to the Rift Valley in Eastern Africa, where she digs for the evolutionary origins of humankind -- and suggests a stunning new vision of our competing ancestors.

Dr. Mark Hebblewhite comes to the SciShow studio to talk to Hank about his research into ungulate herbivores and their predator-prey relationships with a variety of carnivores.

Are We Really 99% Chimp?
