It may produce creepy images with way too many dogs and eyeballs, but Google’s DeepDream program is actually a valuable window into artificial intelligence.

So last episode we talked about some basic file formats, but what we didn’t talk about is compression. Often files are way too large to be easily stored on hard drives or transferred over the Internet - the solution, unsurprisingly, is...

* Viewer discretion advised. This video includes discussion of mature topics and may be inappropriate for some audiences. We're so used to narratives out of Africa being about war, poverty and devastation, says TED Fellow Wanuri Kahiu....

We use algorithms every day for things like image searches, predictive text, and securing sensitive data. Algorithms show up all over nature, too, in places like your immune system and schools of fish, and computer scientists...

Art fair curator Touria el Glaoui is on a mission to showcase vital new art from African nations and the diaspora. She shares beautiful, inspiring, thrilling contemporary art that tells powerful stories of African identity and history --...

Imagine being able to see artwork in the greatest museums around the world without leaving your chair. Driven by his passion for art, Amit Sood tells the story of how he developed Art Project to let people do just that.

When and how did the universe begin? A global group of astronomers wants to answer that question by peering as far back in time as a large new telescope will let us see. Wendy Freedman headed the creation of the Giant Magellan Telescope,...

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of...

This year's end News episode wraps up with nothing but superlatives: the biggest, oldest, first, last, smallest and hottest developments in science from 2012.

Though we’ve been able detect thousands of exoplanets in the last few decades, we’ve now directly imaged an exoplanet that changes our whole perspective on how we think planets like Jupiter form!

Information designer Tom Wujec talks through three areas of the brain that help us understand words, images, feelings, connections. In this short talk from TEDU, he asks: How can we best engage our brains to help us better understand big...

MU69 seems to be much flatter than we thought and the Gaia space telescope can tell us where galaxies have been and, maybe, where they're going.

Blaise Aguera y Arcas leads a dazzling demo of Photosynth, software that could transform the way we look at digital images. Using still photos culled from the Web, Photosynth builds breathtaking dreamscapes and lets us navigate them.

This week in space news, a new makeover for one of the Hubble Telescope's most famous images, and tips on spotting Comet Lovejoy in the night sky.

SciShow Space News takes you to the solar system's own Death Star -- Saturn's moon Mimas, where something mysterious is going on. Plus, we share a stunning new photo from the Hubble Space Telescope that holds a few surprises!

Building sophisticated educational tools out of cheap parts, Johnny Lee demos his cool Wii Remote hacks, which turn the $40 video game controller into a digital whiteboard, a touchscreen and a head-mounted 3-D viewer.

Matt Mills and Tamara Roukaerts demonstrate Aurasma, a new augmented reality tool that can seamlessly animate the world as seen through a smartphone. Going beyond previous augmented reality, their "auras" can do everything from making a...

An overview of backpropagation, the algorithm behind how neural networks learn.

How is it that you can be looking at a distinct object in front of you, yet picture something entirely different in your mind? The inner workings of what’s happening in our brains to allow this is a puzzle that scientists are now...

Today's AI algorithms require tens of thousands of expensive medical images to detect a patient's disease. What if we could drastically reduce the amount of data needed to train an AI, making diagnoses low-cost and more effective? TED...

A lot of our knowledge of the inner solar system was gained fairly recently, and the Mariner program led the way!

Today on the SciShow Talk Show, our Technical Director Nick Jenkins stumps Hank about how many frames per second the human eye can see, and Jessi from Animal Wonders shares Hara the Harris's hawk.

An overview of what a neural network is, introduced in the context of recognizing hand-written digits.

In 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper. The location was apparently empty, and the whole endeavor was risky _ what, if anything, was going to show up? But what came back was nothing...
