We're building an artificial intelligence-powered dystopia, one click at a time, says techno-sociologist Zeynep Tufekci. In an eye-opening talk, she details how the same algorithms companies like Facebook, Google and Amazon use to get...

A mini-lesson on cause and effect.

Early diagnosis of autism spectrum disorder can improve the lives of everyone affected, but the complex network of causes make it incredibly difficult to predict. At TEDxPeachtree, Ami Klin describes a new early detection method that...

We've been to the moon, we've mapped the continents, we've even been to the deepest point in the ocean -- twice. What's left for the next generation to explore? Biologist and explorer Nathan Wolfe suggests this answer: Almost everything....

Is a universal translator possible in real life? We already have many programs that claim to be able to take a word, sentence, or entire book in one language and translate it into almost any other. The reality, however, is a bit more...

It turns out that dogs are born with a lot of their ability to interact with people, and songbirds have to mute their minds to stay in sync during their quick back and forth duets.

Inventor Manu Prakash turns everyday materials into powerful scientific devices, from paper microscopes to a clever new mosquito tracker. From the TED Fellows stage, he demos Paperfuge, a hand-powered centrifuge inspired by a spinning...

You're the realm's greatest mathematician, but ever since you criticized the Emperor's tax laws, you've been locked in the dungeon. Luckily for you, one of the Emperor's governors has been convicted of paying his taxes with a counterfeit...

They say everyone has a doppelganger, but is that really true? This week we meet a young woman who found her own look-alike, and figure out how we actually recognize faces.

Variables: What are they? In the case of engineering, variables are a condition or value that can change. Sometimes we control a variable, sometimes we don't. In this episode of Crash Course Kids, Sabrina chats to us about how variables...

Which is a bigger deal to you? The discovery that there's probably more water on Jupiter's moon Ganymede than all the oceans on Earth? Or the fact that you can now help NASA find asteroids? Learn about both, then decide for yourself!

Every city has its neighborhoods, cliques and clubs, the hidden lines that join and divide people in the same town. What can we learn about cities by looking at what people share online? Starting with his own home town of Baltimore, Dave...

An analysis of samples taken from the Iceman’s stomach has revealed new details about what people were eating thousands of years ago!

One billion people worldwide are living with a disability, and too many of them are left unemployed or feeling like they need to hide their conditions due to discriminatory hiring practices, says social innovator and TED Fellow Ryan...

Oceanographer Paul Snelgrove shares the results of a ten-year project with one goal: to take a census of all the life in the oceans. He shares amazing photos of some of the surprising finds of the Census of Marine Life.

It's time to design some trials. Sometimes engineers need to figure out how to test ideas. In order to do that, we need to design trials to find failure points and see how things are going to work in the real world (with gravity, wind,...

Researchers mapped the mammoth family tree by extracting DNA from fossils. Also, scientists found some sessile animals living under Antarctica's ice shelf, and they're really cool.

Self-driving cars were just the start. What's the future of big data-driven technology and design? In a thrilling science talk, Kenneth Cukier looks at what's next for machine learning -- and human knowledge.

Fevers are one of our best weapons against infections, but they don't work like you might think.

It’s probably not a surprise that many ancient texts are a bit worn out and tattered, and that makes deciphering what they say quite a task. But with new computer tech and artificial intelligence, we are getting much clearer glimpses of...

In a neutralization reaction (or acid-base reaction) a proton is transferred from the Brinsted--Lowry acid to the Brinsted--Lowry base. Water is amphoteric and so it can serve as either an acid or a base in a neutralization reaction. ...

How many species are there on Earth? In biology, this is one of a fundamental question that we still don't have a very good answer for. Imagine if chemists didn't know all the elements of the periodic table, or if physicists didn't know...
