TED - Ideas worth spreading 

What the Russian Revolution would have looked like on social media | Mikhail Zygar

History is written by the victors, as the saying goes -- but what would it look like if it was written by everyone? Journalist and TED Fellow Mikhail Zygar is on a mission to show us with Project1917, a "social network for dead people" that posts the real diaries and letters of more than 3,000 people who lived during the Russian Revolution. By showing the daily thoughts of the likes of Lenin, Trotsky and many less celebrated figures, the project sheds new light on history as it once was -- and as it could have been. Learn more about this digital retelling of the past as well as Zygar's latest project about the transformative year of 1968.... läs mer »

What your smart devices know (and share) about you | Kashmir Hill and Surya Mattu

Once your smart devices can talk to you, who else are they talking to? Kashmir Hill and Surya Mattu wanted to find out -- so they outfitted Hill's apartment with 18 different internet-connected devices and built a special router to track how often they contacted their servers and see what they were reporting back. The results were surprising -- and more than a little bit creepy. Learn more about what the data from your smart devices reveals about your sleep schedule, TV binges and even your tooth-brushing habits -- and how tech companies could use it to target and profile you. (This talk contains mature language.)... läs mer »

The power of diversity within yourself | Rebeca Hwang

Rebeca Hwang has spent a lifetime juggling identities -- Korean heritage, Argentinian upbringing, education in the United States -- and for a long time she had difficulty finding a place in the world to call home. Yet along with these challenges came a pivotal realization: that a diverse background is a distinct advantage in today's globalized world. In this personal talk, Hwang reveals the endless benefits of embracing our complex identities -- and shares her hopes for creating a world where identities aren't used to alienate but to bring people together instead.... läs mer »

The mission to create a searchable database of Earth's surface | Will Marshall

What if you could search the surface of the Earth the same way you search the internet? Will Marshall and his team at Planet use the world's largest fleet of satellites to image the entire Earth every day. Now they're moving on to a new project: using AI to index all the objects on the planet over time -- which could make ships, trees, houses and everything else on Earth searchable, the same way you search Google. He shares a vision for how this database can become a living record of the immense physical changes happening across the globe. "You can't fix what you can't see," Marshall says. "We want to give people the tools to see change and take action."... läs mer »

A new way to monitor vital signs (that can see through walls) | Dina Katabi

At MIT, Dina Katabi and her team are working on a bold new way to monitor patients' vital signs in a hospital (or even at home), without wearables or bulky, beeping devices. Bonus: it can see through walls. In a mind-blowing talk and demo, Katabi previews a system that captures the reflections of signals like Wi-Fi as they bounce off people, creating a reliable record of vitals for healthcare workers and patients. And in a brief Q&A with TED curator Helen Walters, Katabi discusses safeguards being put in place to prevent people from using this tech to monitor somebody without their consent.... läs mer »

How to build synthetic DNA and send it across the internet | Dan Gibson

Biologist Dan Gibson edits and programs DNA, just like coders program a computer. But his "code" creates life, giving scientists the power to convert digital information into biological material like proteins and vaccines. Now he's on to a new project: "biological transportation," which holds the promise of beaming new medicines across the globe over the internet. Learn more about how this technology could change the way we respond to disease outbreaks and enable us to download personalized prescriptions in our homes.... läs mer »

How we study the microbes living in your gut | Dan Knights

There are about a hundred trillion microbes living inside your gut -- protecting you from infection, aiding digestion and regulating your immune system. As our bodies have adapted to life in modern society, we've started to lose some of our normal microbes; at the same time, diseases linked to a loss of diversity in microbiome are skyrocketing in developed nations. Computational microbiologist Dan Knights shares some intriguing discoveries about the differences in the microbiomes of people in developing countries compared to the US, and how they might affect our health. Learn more about the world of microbes living inside you -- and the work being done to create tools to restore and replenish them.... läs mer »

How farming could employ Africa's young workforce -- and help build peace | Kola Masha

The rapid growth of the Chinese internet -- and where it's headed | Gary Liu

The Chinese internet has grown at a staggering pace -- it now has more users than the combined populations of the US, UK, Russia, Germany, France and Canada. Even with its imperfections, the lives of once-forgotten populations have been irrevocably elevated because of it, says South China Morning Post CEO Gary Liu. In a fascinating talk, Liu details how the tech industry in China has developed -- from the innovative, like AI-optimized train travel, to the dystopian, like a social credit rating that both rewards and restricts citizens.... läs mer »

A new way to remove CO2 from the atmosphere | Jennifer Wilcox

Our planet has a carbon problem -- if we don't start removing carbon dioxide from the atmosphere, we'll grow hotter, faster. Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical reactions that capture and reuse CO2 in much the same way trees do ... but at a vast scale. This detailed talk reviews both the promise and the pitfalls.... läs mer »

The tiny creature that secretly powers the planet | Penny Chisholm

Oceanographer Penny Chisholm introduces us to an amazing little being: Prochlorococcus, the most abundant photosynthetic species on the planet. A marine microbe that has existed for millions of years, Prochlorococcus wasn't discovered until the mid-1980s -- but its ancient genetic code may hold clues to how we can reduce our dependence on fossil fuels.... läs mer »
