What kinds of stories move us to act? To answer this question, creative technologist Heidi Boisvert is measuring how people's brains and bodies unconsciously respond to different media. She shows how she's using this data to determine the specific narrative ingredients that inspire empathy and justice -- and spark large-scale social change.
Ever wondered how your smartphone works? Take a journey down to the atomic level with scientist Cathy Mulzer, who reveals how almost every component of our high-powered devices exists thanks to chemists -- and not the Silicon Valley entrepreneurs that come to most people's minds. As she puts it: "Chemistry is the hero of electronic communications."
In this glimpse into our technological future, cryptographer Craig Costello discusses the world-altering potential of quantum computers, which could shatter the limits set by today's machines -- and give code breakers a master key to the digital world. See how Costello and his fellow cryptographers are racing to reinvent encryption and secure the internet.
Social media has become our new home. Can we build it better? Taking design cues from urban planners and social scientists, technologist Eli Pariser shows how the problems we're encountering on digital platforms aren't all that new -- and shares how, by following the model of thriving towns and cities, we can create trustworthy online communities.
Millions of images and videos are uploaded to the internet each day, yet we rarely see shocking and disturbing content in our social media feeds. Who's keeping the internet "clean" for us? In this eye-opening talk, documentarians Hans Block and Moritz Riesewieck take us inside the shadowy world of online content moderators -- the people contracted by major platforms like Facebook, Twitter and Google to rid the internet of toxic material. Learn more about the psychological impact of this kind of work -- and how "digital cleaning" influences what all of us see and think.
Energy poverty, or the lack of access to electricity and other basic energy services, affects nearly two-thirds of Sub-Saharan Africa. As the region's population continues to increase, so will the need to build a new energy system to grow with it, says Rose M. Mutiso. In a bold talk, she discusses how a balanced mix of solutions like solar, wind farms, geothermal power and modern grids could create a high-energy future for Africa -- providing reliable electricity, creating jobs and raising incomes.
How can we stop the spread of misleading, sometimes dangerous content while maintaining an internet with freedom of expression at its core? Misinformation expert Claire Wardle explores the new challenges of our polluted online environment and maps out a plan to transform the internet into a place of trust -- with the help everyday users. "Together, let's rebuild our information commons," she says.
The danger of artificial intelligence isn't that it's going to rebel against us, but that it's going to do exactly what we ask it to do, says AI researcher Janelle Shane. Sharing the weird, sometimes alarming antics of AI algorithms as they try to solve human problems -- like creating new ice cream flavors or recognizing cars on the road -- Shane shows why AI doesn't yet measure up to real brains.
Nearly 800 million people worldwide depend on cassava for survival -- but this critical food source is under attack by entirely preventable viruses, says computational biologist and TED Senior Fellow Laura Boykin. She takes us to the farms in East Africa where she's working with a diverse team of scientists to help farmers keep their crops healthy using a portable DNA lab and mini supercomputer that can identify viruses in hours, instead of months.
A full third of the world's population -- 2.6 billion people -- play video games, plugging into massive networks of interaction that have opened up opportunities well beyond entertainment. In a talk about the future of the medium, entrepreneur Herman Narula makes the case for a new understanding of gaming -- one that includes the power to create new worlds, connect people and shape the economy.
To study a system as complex as the entire universe, astrophysicists need to be experts at extracting simple solutions from large data sets. What else could they do with this expertise? In an interdisciplinary talk, TED Fellow and astrophysicist Federica Bianco explains how she uses astrophysical data analysis to solve urban and social problems -- as well as stellar mysteries.
The use of deepfake technology to manipulate video and audio for malicious purposes -- whether it's to stoke violence or defame politicians and journalists -- is becoming a real threat. As these tools become more accessible and their products more realistic, how will they shape what we believe about the world? In a portentous talk, law professor Danielle Citron reveals how deepfakes magnify our distrust -- and suggests approaches to safeguarding the truth.
Taking design cues from origami, robotician Jamie Paik and her team created "robogamis": folding robots made out super-thin materials that can reshape and transform themselves. In this talk and tech demo, Paik shows how robogamis could adapt to achieve a variety of tasks on earth (or in space) and demonstrates how they roll, jump, catapult like a slingshot and even pulse like a beating heart.
Glenn Cantave uses technology to highlight narratives of the oppressed. In a tour of immersive visual projects, he shares his work with the team at Movers and Shakers NYC, a coalition that executes direct action and advocacy campaigns for marginalized communities using virtual reality, augmented reality and the creative arts.
What would it take to settle Mars? In a talk about the future of space exploration, Lynn Rothschild reviews the immense challenges to living elsewhere in the universe and proposes some bold, creative solutions to making a home off planet Earth -- like "growing" houses out of fungi or using bacteria to help generate electricity.
Humans have been studying the stars for thousands of years, but astrophysicist Juna Kollmeier is on a special mission: creating the most detailed 3-D maps of the universe ever made. Journey across the cosmos as she shares her team's work on the Sloan Digital Sky Survey, imaging millions of stars, black holes and galaxies in unprecedented detail. If we maintain our pace, she says, we can map every large galaxy in the observable universe by 2060. "We've gone from arranging clamshells to general relativity in a few thousand years," she says. "If we hang on 40 more, we can map all the galaxies."
TED Fellow and astronomer Erika Hamden leads the team building FIREBall, a telescope that hangs from a giant balloon at the very edge of space and looks for clues about how stars are created. She takes us inside the roller-coaster, decade-long journey to get the telescope from an idea into orbit -- and shows how failure is inevitable when you're pushing the limits of knowledge.
Try talking to yourself without opening your mouth, by simply saying words internally. What if you could search the internet like that -- and get an answer back? In the first live public demo of his new technology, TED Fellow Arnav Kapur introduces AlterEgo: a wearable AI device with the potential to let you silently talk to and get information from a computer system, like a voice inside your head. Learn more about how the device works and the far-reaching implications of this new kind of human-computer interaction.
In an astonishing talk and tech demo, software researcher Doug Roble debuts "DigiDoug": a real-time, 3-D, digital rendering of his likeness that's accurate down to the scale of pores and wrinkles. Powered by an inertial motion capture suit, deep neural networks and enormous amounts of data, DigiDoug renders the real Doug's emotions (and even how his blood flows and eyelashes move) in striking detail. Learn more about how this exciting tech was built -- and its applications in movies, virtual assistants and beyond.
Designer Ivan Poupyrev wants to integrate technology into everyday objects to make them more useful and fun -- like a jacket you can use to answer phone calls or a houseplant you can play like a keyboard. In a talk and tech demo, he lays out his vision for a physical world that's more deeply connected to the internet and shows how, with a little collaboration, we can get there. Unveiled in this talk: Poupyrev announces that his newest device, Jacquard, is now publicly available for all designers to use.

Fascinating talk, a great insight to a very likely future of digital storage. It amazes me how scientists and engineers can come up with ludicrous ideas like this and make them a reality The human race are absolutely pioneers and pushing the limits of evolution with the technological age. Its both exciting and scary to see what's next
