How urban spaces can preserve history and build community | Walter Hood
00:14:14
Can public spaces both reclaim the past and embrace the future? Landscape architect Walter Hood has explored this question over the course of an iconic career, with projects ranging from Lafayette Square Park in San Francisco to the upcoming International African American Museum in Charleston, South Carolina. In this inspiring talk packed with images of his work, Hood shares the five simple concepts that guide his approach to creating spaces that illuminate shared memories and force us to look at one another in a different way.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/i5zpON5h9lQ" height="1" width="1" alt=""/>

How cancer cells communicate -- and how we can slow them down | Hasini Jayatilaka
00:10:19
When cancer cells are closely packed together in a tumor, they're able to communicate with each other and coordinate their movement throughout the body. What if we could interrupt this process? In this accessible talk about cutting-edge science, Hasini Jayatilaka shares her work on an innovative method to stop cancer cells from communicating -- and halt their fatal ability to spread.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/-Zni3gWQOWw" height="1" width="1" alt=""/>

What a scrapyard in Ghana can teach us about innovation | DK Osseo-Asare
00:14:17
In Agbogbloshie, a community in Accra, Ghana, people descend on a scrapyard to mine electronic waste for recyclable materials. Without formal training, these urban miners often teach themselves the workings of electronics by taking them apart and putting them together again. Designer DK Osseo-Asare wondered: What would happen if we connected these self-taught techies with students and young professionals in STEAM fields? The result: a growing maker community where people engage in peer-to-peer, hands-on education, motivated by what they want to create. Learn more about how this African makerspace is pioneering a grassroots circular economy.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/QoowR5dbnCE" height="1" width="1" alt=""/>

Why I fight for the education of refugee girls (like me) | Mary Maker
00:16:47
After fleeing war-torn South Sudan as a child, Mary Maker found security and hope in the school at Kenya's Kakuma Refugee Camp. Now a teacher of young refugees herself, she sees education as an essential tool for rebuilding lives -- and empowering a generation of girls who are too often denied entrance into the classroom. "For the child of war, an education can turn their tears of loss into a passion for peace," Maker says.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/XV3DGzXBpBg" height="1" width="1" alt=""/>

The little risks you can take to increase your luck | Tina Seelig
00:11:39
Luck is rarely a lightning strike, isolated and dramatic -- it's much more like the wind, blowing constantly. Catching more of it is easy but not obvious. In this insightful talk, Stanford engineering school professor Tina Seelig shares three unexpected ways to increase your luck -- and your ability to see and seize opportunities.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/LDSYnJUnw18" height="1" width="1" alt=""/>

How teachers can help kids find their political voices | Sydney Chaffee
00:16:59
Social justice belongs in our schools, says educator Sydney Chaffee. In a bold talk, she shows how teaching students to engage in activism helps them build important academic and life skills -- and asks us to rethink how we can use education to help kids find their voices. "Teaching will always be a political act," Chaffee says. "We can't be afraid of our students' power. Their power will help them make tomorrow better."<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/DODECgRYBnQ" height="1" width="1" alt=""/>

You may be accidentally investing in cigarette companies | Bronwyn King
00:14:38
Tobacco causes more than seven million deaths every year -- and many of us are far more complicit in the problem than we realize. In a bold talk, oncologist Dr. Bronwyn King tells the story of how she uncovered the deep ties between the tobacco industry and the entire global finance sector, which invests our money in cigarette companies through big banks, insurers and pension funds. Learn how Dr. King has ignited a worldwide movement to create tobacco-free investments and how each of us can play a role in ending this epidemic.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/VVmMJlH_11o" height="1" width="1" alt=""/>

How to stop swiping and find your person on dating apps | Christina Wallace
00:05:19
Let's face it, online dating can suck. So many potential people, so much time wasted -- is it even worth it? Podcaster and entrepreneur Christina Wallace thinks so, if you do it right. In a funny, practical talk, Wallace shares how she used her MBA skill set to invent a "zero date" approach and get off swipe-based apps -- and how you can, too.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/SMz8rN8qM9Y" height="1" width="1" alt=""/>

How AI is making it easier to diagnose disease | Pratik Shah
00:04:59
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 Fellow Pratik Shah is working on a clever system to do just that. Using an unorthodox AI approach, Shah has developed a technology that requires as few as 50 images to develop a working algorithm -- and can even use photos taken on doctors' cell phones to provide a diagnosis. Learn more about how this new way to analyze medical information could lead to earlier detection of life-threatening illnesses and bring AI-assisted diagnosis to more health care settings worldwide.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/za50rkHp_Cs" height="1" width="1" alt=""/>

Why doctors are offering free tax prep in their waiting rooms | Lucy Marcil
00:04:56
More than 90 percent of children in the US see a doctor at least once a year, which means countless hours spent in waiting rooms for parents. What if those hours could be used for something productive -- like saving money? Through her organization StreetCred, pediatrician and TED Fellow Lucy Marcil is offering free tax prep to parents right in the waiting room, reimagining what a doctor's visit can look like and helping to lift families out of poverty. Learn more about how free tax prep and guidance could be the best poverty prescription we have in the US.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/CCPn3JSK7c0" height="1" width="1" alt=""/>

Where are all the aliens? | Stephen Webb
00:13:18
The universe is incredibly old, astoundingly vast and populated by trillions of planets -- so where are all the aliens? Astronomer Stephen Webb has an explanation: we're alone in the universe. In a mind-expanding talk, he spells out the remarkable barriers a planet would need to clear in order to host an extraterrestrial civilization -- and makes a case for the beauty of our potential cosmic loneliness. "The silence of the universe is shouting, 'We're the creatures who got lucky,'" Webb says.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/Gv7sgxTTbK4" height="1" width="1" alt=""/>

What the Russian Revolution would have looked like on social media | Mikhail Zygar
00:04:49
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.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/veK27DBaze8" height="1" width="1" alt=""/>

What your smart devices know (and share) about you | Kashmir Hill and Surya Mattu
00:09:05
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.)<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/ttbCIEvichc" height="1" width="1" alt=""/>

The power of diversity within yourself | Rebeca Hwang
00:09:44
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.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/YIx3nbEAgKU" height="1" width="1" alt=""/>

The mission to create a searchable database of Earth's surface | Will Marshall
00:06:13
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."<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/iTXKP4BfJ1Y" height="1" width="1" alt=""/>

How we study the microbes living in your gut | Dan Knights
00:09:56
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.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/s09XZm_NVH0" height="1" width="1" alt=""/>

The rapid growth of the Chinese internet -- and where it's headed | Gary Liu
00:12:41
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.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/k61E27fj9GQ" height="1" width="1" alt=""/>

The agony of opioid withdrawal -- and what doctors should tell patients about it | Travis Rieder
00:14:17
The United States accounts for five percent of the world's population but consumes almost 70 percent of the total global opioid supply, creating an epidemic that has resulted in tens of thousands of deaths each year. How did we get here, and what can we do about it? In this personal talk, Travis Rieder recounts the painful, often-hidden struggle of opioid withdrawal and reveals how doctors who are quick to prescribe (and overprescribe) opioids aren't equipped with the tools to eventually get people off the meds.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/Ly4em6JGpxk" height="1" width="1" alt=""/>

The story of 'Oumuamua, the first visitor from another star system | Karen J. Meech
00:13:24
In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" -- raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/RHQAyDwHaEU" height="1" width="1" alt=""/>

The symbols of systemic racism -- and how to take away their power | Paul Rucker
00:07:01
Multidisciplinary artist and TED Fellow Paul Rucker is unstitching the legacy of systemic racism in the United States. A collector of artifacts connected to the history of slavery -- from branding irons and shackles to postcards depicting lynchings -- Rucker couldn't find an undamaged Ku Klux Klan robe for his collection, so he began making his own. The result: striking garments in non-traditional fabrics like kente cloth, camouflage and silk that confront the normalization of systemic racism in the US. "If we as a people collectively look at these objects and realize that they are part of our history, we can find a way to where they have no more power over us," Rucker says.

What if we eliminated one of the world's oldest diseases? | Caroline Harper
00:10:12
Thousands of years ago, ancient Nubians drew pictures on tomb walls of a terrible disease that turns the eyelids inside out and causes blindness. This disease, trachoma, is still a scourge in many parts of the world today -- but it's also completely preventable, says Caroline Harper. Armed with data from a global mapping project, Harper's organization Sightsavers has a plan: to focus on countries where funding gaps stand in the way of eliminating the disease and ramp up efforts where the need is most severe. Learn more about their goal of consigning trachoma to the history books -- and how you can help. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/cs6wFnDOowY" height="1" width="1" alt=""/>

How we can design timeless cities for our collective future | Vishaan Chakrabarti
00:13:13
There's a creeping sameness in many of our newest urban buildings and streetscapes, says architect Vishaan Chakrabarti. And this physical homogeneity -- the result of regulations, mass production, safety issues and cost considerations, among other factors -- has blanketed our planet in a social and psychological homogeneity, too. In this visionary talk, Chakrabarti calls for a return to designing magnetic, lyrical cities that embody their local cultures and adapt to the needs of our changing world and climate.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/iPa--27Z-Lc" height="1" width="1" alt=""/>

The nightmare videos of children's YouTube -- and what's wrong with the internet today | James Bridle
00:16:32
Writer and artist James Bridle uncovers a dark, strange corner of the internet, where unknown people or groups on YouTube hack the brains of young children in return for advertising revenue. From "surprise egg" reveals and the "Finger Family Song" to algorithmically created mashups of familiar cartoon characters in violent situations, these videos exploit and terrify young minds -- and they tell us something about where our increasingly data-driven world is headed. "We need to stop thinking about technology as a solution to all of our problems, but think of it as a guide to what those problems actually are, so we can start thinking about them properly and start to address them," Bridle says.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/dzws81n0CIo" height="1" width="1" alt=""/>

Why you should love gross science | Anna Rothschild
00:13:12
What can we learn from the slimy, smelly side of life? In this playful talk, science journalist Anna Rothschild shows us the hidden wisdom of "gross stuff" and explains why avoiding the creepy underbelly of nature, medicine and technology closes us off to important sources of knowledge about our health and the world. "When we explore the gross side of life, we find insights that we never would have thought we'd find, and we even often reveal beauty that we didn't think was there," Rothschild says.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/OL3EdMlA918" height="1" width="1" alt=""/>

How Netflix changed entertainment -- and where it's headed | Reed Hastings
00:20:51
Netflix changed the world of entertainment -- first with DVD-by-mail, then with streaming media and then again with sensational original shows like "Orange Is the New Black" and "Stranger Things" -- but not without taking its fair share of risks. In conversation with TED curator Chris Anderson, Netflix co-founder and CEO Reed Hastings discusses the company's bold internal culture, the powerful algorithm that fuels their recommendations, the $8 billion worth of content they're investing in this year and his philanthropic pursuits supporting innovative education, among much more.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/zda9wPVRBjc" height="1" width="1" alt=""/>

How we can bring mental health support to refugees | Essam Daod
00:05:26
The global refugee crisis is a mental health catastrophe, leaving millions in need of psychological support to overcome the traumas of dislocation and conflict. To undo the damage, child psychiatrist and TED Fellow Essam Daod has been working in camps, rescue boats and the shorelines of Greece and the Mediterranean Sea to help refugees (a quarter of which are children) reframe their experiences through short, powerful psychological interventions. "We can all do something to prevent this mental health catastrophe," Daod says. "We need to acknowledge that first aid is not just needed for the body, but it has also to include the mind, the soul."<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/S17jz6CjqYE" height="1" width="1" alt=""/>

Technology that knows what you're feeling | Poppy Crum
00:12:42
What happens when technology knows more about us than we do? Poppy Crum studies how we express emotions -- and she suggests the end of the poker face is near, as new tech makes it easy to see the signals that give away how we're feeling. In a talk and demo, she shows how "empathetic technology" can read physical signals like body temperature and the chemical composition of our breath to inform on our emotional state. For better or for worse. "If we recognize the power of becoming technological empaths, we get this opportunity where technology can help us bridge the emotional and cognitive divide," Crum says.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/V49G5BVSWD0" height="1" width="1" alt=""/>

The surprising science of alpha males | Frans de Waal
00:15:54
In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/UocfRyUm8xo" height="1" width="1" alt=""/>

Can home cooking change the world? | Gastón Acurio
00:13:25
When Gastón Acurio started his now world-famous restaurant Astrid & Gastón in the 1990s, no one suspected that he would elevate the Peruvian home-cooking he grew up with to haute cuisine. Nearly thirty years and a storied career later, the chef wants the rest of us to embrace our culinary roots and transform the world with the meals we prepare each day.

Four billion years of evolution in six minutes | Prosanta Chakrabarty
00:05:41
Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we're a small part of a complex, four-billion-year process -- and not the end of the line. "We're not the goal of evolution," Chakrabarty says. "Think of us all as young leaves on this ancient and gigantic tree of life -- connected by invisible branches not just to each other, but to our extinct relatives and our evolutionary ancestors."<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/XBIvLOzwuug" height="1" width="1" alt=""/>

How I'm bringing queer pride to my rural village | Katlego Kolanyane-Kesupile
00:05:49
In a poetic, personal talk, TED Fellow Katlego Kolanyane-Kesupile examines the connection between her modern queer lifestyle and her childhood upbringing in a rural village in Botswana. "In a time where being brown, queer, African and seen as worthy of space means being everything but rural, I fear that we're erasing the very struggles that got us to where we are now," she says. "Indigenizing my queerness means bridging the many exceptional parts of myself."<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/Rt5BLnhRFNg" height="1" width="1" alt=""/>

The incredible potential of flexible, soft robots | Giada Gerboni
00:09:27
Robots are designed for speed and precision -- but their rigidity has often limited how they're used. In this illuminating talk, biomedical engineer Giada Gerboni shares the latest developments in "soft robotics," an emerging field that aims to create nimble machines that imitate nature, like a robotic octopus. Learn more about how these flexible structures could play a critical role in surgery, medicine and our daily lives.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/sMIwhZHMJg0" height="1" width="1" alt=""/>

How to get empowered, not overpowered, by AI | Max Tegmark
00:17:15
Many artificial intelligence researchers expect AI to outsmart humans at all tasks and jobs within decades, enabling a future where we're restricted only by the laws of physics, not the limits of our intelligence. MIT physicist and AI researcher Max Tegmark separates the real opportunities and threats from the myths, describing the concrete steps we should take today to ensure that AI ends up being the best -- rather than worst -- thing to ever happen to humanity.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/3bwA-dso14M" height="1" width="1" alt=""/>

What we'll learn about the brain in the next century | Sam Rodriques
00:13:31
In this imaginative talk, neuroengineer Sam Rodriques takes us on a thrilling tour of the next 100 years in brain science. He envisions strange (and sometimes frightening) innovations that may be the key to understanding and treating brain disease -- like lasers that drill tiny holes in our skulls and allow probes to study the electrical activity of our neurons.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/dkQ5ycMD19I" height="1" width="1" alt=""/>

Why the secret to success is setting the right goals | John Doerr
00:11:51
Our leaders and institutions are failing us, but it's not always because they're bad or unethical, says venture capitalist John Doerr -- often, it's simply because they're leading us toward the wrong objectives. In this practical talk, Doerr shows us how we can get back on track with "Objectives and Key Results," or OKRs -- a goal-setting system that's been employed by the likes of Google, Intel and Bono to set and execute on audacious goals. Learn more about how setting the right goals can mean the difference between success and failure -- and how we can use OKRs to hold our leaders and ourselves accountable.<img src="http://feeds.feedburner.com/~r/TEDTalks_video/~4/kqAeKU6-XUA" height="1" width="1" alt=""/>
