Listen in to hear what the man who makes a living from predicting the future arc of technology thinks is coming our way next -- including a specific prediction of when he thinks technology...

When we hear the word radiation, it's tempting to picture huge explosions and frightening mutations. But that's not the full story — radiation also applies to rainbows and a doctor examining an X-ray. So what is it, really, and how much should we worry about its effects? Matt Anticole describes the different types of radiation. [Directed by Tinm...

Two hundred million years ago, our mammal ancestors developed a new brain feature: the neocortex. This stamp-sized piece of tissue (wrapped around a brain the size of a walnut) is the key to what humanity has become. Now, futurist Ray Kurzweil suggests, we should get ready for the next big leap in brain power, as we tap into the computing power ...

In many ways, our memories make us who we are, helping us remember our past, learn and retain skills, and plan for the future. And for the computers that often act as extensions of ourselves, memory plays much the same role. Kanawat Senanan explains how computer memory works. [Directed by TED-Ed, narrated by Addison Anderson, music by Carlos Pal...

Prior to the mid-20th century, art restorers took a heavy-handed approach, often drastically altering paintings in the name of "improving" art. Today, they focus on keeping the original work intact with minimal intervention, and must regularly contend with past modifications. So, how is damaged artwork repaired? Noah Charney explains the painsta...

In 2012, a team of researchers set a world record, transmitting 1 petabit of data— that's 10,000 hours of high-def video— over a fifty-kilometer cable, in a second. This wasn't just any cable. It was a souped-up version of fiber optics, the hidden network that links our planet and makes the internet possible. What is fiber optics and how does it...

The founder of Sirius XM satellite radio, Martine Rothblatt now heads up a drug company that makes life-saving medicines for rare diseases (including one drug that saved her own daughter's life). Meanwhile she is working to preserve the consciousness of the woman she loves in a digital file ... and a companion robot. In an onstage conversation w...

What if technology could connect us more deeply with our surroundings instead of distracting us from the real world? With the Meta 2, an augmented reality headset that makes it possible for users to see, grab and move holograms just like physical objects, Meron Gribetz hopes to extend our senses through a more natural machine. Join Gribetz as he...

A shooting star crashes onto Earth and a hideous blob emerges. It creeps and leaps, it glides and slides. It's also unstoppable: no matter what you throw at it, it just re-grows and continues its rampage. The only way to save the planet is to cut the entire blob into precise acute triangles while it sleeps, rendering it inert. Can you stop the b...

Depression is the leading cause of disability in the world; in the United States, close to ten percent of adults struggle with the disease. But because it's a mental illness, it can be a lot harder to understand than, say, high cholesterol. Helen M. Farrell examines the symptoms and treatments of depression, and gives some tips for how you might...

Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes. But is there any way to destroy a black hole? Fabio Pacucci...

As the cofounder of Google DeepMind, Shane Legg is driving one of the greatest transformations in history: the development of artificial general intelligence (AGI). He envisions a system with human-like intelligence that would be exponentially smarter than today's AI, with limitless possibilities and applications. In conversation with head of TE...

In 2008, two 9,000-year old skeletons were found with their bones infected by an all too familiar bacterium. The ancient Greeks knew its effects as phthisis; the Incans called it chaky oncay; and today we call it tuberculosis, or TB. TB is still one of the world's most infectious killers, causing more deaths than malaria or even HIV. How has it ...

What if we could use brain waves to treat Alzheimer's? Professor and neuroscientist Li-Huei Tsai details a promising new approach to artificially stimulate gamma brain waves using light and sound therapy, to increase connectivity and synchrony and delay the onset of this deadly disease. This non-invasive therapy has already been shown to work in...

Can AI help us answer life's biggest questions? In this visionary conversation, Google DeepMind cofounder and CEO Demis Hassabis delves into the history and incredible capabilities of AI with head of TED Chris Anderson. Hassabis explains how AI models like AlphaFold — which accurately predicted the shapes of all 200 million proteins known to sci...

As COVID-19 continues to spread, the world is facing two existential threats at once: a public health emergency and an economic crisis. Political theorist Danielle Allen describes how we can ethically and democratically address both problems by scaling up "smart testing," which would track positive cases with peer-to-peer software on people's ce...

Legendary ocean researcher Sylvia Earle shares astonishing images of the ocean -- and shocking stats about its rapid decline -- as she makes her TED Prize wish: that we will join her in protecting the vital blue heart of the planet.

Barry Schwartz makes a passionate call for "practical wisdom" as an antidote to a society gone mad with bureaucracy. He argues powerfully that rules often fail us, incentives often backfire, and practical, everyday wisdom will help rebuild our world.

Daniel Kish has been blind since he was 13 months old, but has learned to "see" using a form of echolocation. He clicks his tongue and sends out flashes of sound that bounce off surfaces in the environment and return to him, helping him to construct an understanding of the space around him. In a rousing talk, Kish shows how this works -- and ask...

Sampling isn't about "hijacking nostalgia wholesale," says Mark Ronson. It's about inserting yourself into the narrative of a song while also pushing that story forward. In this mind-blowingly original talk, watch the DJ scramble 15 TED Talks into an audio-visual omelette, and trace the evolution of "La Di Da Di," Doug E. Fresh and Slick Rick's ...

MIT Media Lab founder Nicholas Negroponte takes you on a journey through the last 30 years of tech. The consummate predictor highlights interfaces and innovations he foresaw in the 1970s and 1980s that were scoffed at then but are ubiquitous today. And he leaves you with one last (absurd? brilliant?) prediction for the coming 30 years.

As humans, we can perceive less than a ten-trillionth of all light waves. "Our experience of reality," says neuroscientist David Eagleman, "is constrained by our biology." He wants to change that. His research into our brain processes has led him to create new interfaces -- such as a sensory vest -- to take in previously unseen information about...

Nuclear power: the energy crisis has even die-hard environmentalists reconsidering it. In this first-ever TED debate, Stewart Brand and Mark Z. Jacobson square off over the pros and cons. A discussion that'll make you think -- and might even change your mind.

Talking about race can be difficult. But Mellody Hobson argues that we need to do it anyway -- boldly and often. Mellody is the president of Ariel Investments, a firm that manages more than 13 billion dollars. And throughout her career and in her personal life, she's experienced just how corrosive it can be when people choose to be "color blind....

From that moment until now, he passed through at least three serious careers – which he talks about with a lot of humour. But how do they all connect? Through this extraordinary gift called life. Andrei Rosu, 41 years old, is the father of two children, has over 15 years of experience in the corporate environment, is an endurance athlete, blogge...
