Mikko Hypponen: How the NSA betrayed the world's trust -- time to act


Recent events have highlighted, underlined and bolded the fact that the United States is performing blanket surveillance on any foreigner whose data passes through an American entity -- whether they are suspected of wrongdoing or not. This means that, essentially, every international user of the internet is being watched, says Mikko Hypponen. An important rant, wrapped with a plea: to find alternative solutions to using American companies for the world's information needs.

See how it works, as a paralyzed rat becomes able to run and navigate stairs.

Rodrigo Canales: The deadly genius of drug cartels

TEDSalon NY2013

Rodrigo Canales: The deadly genius of drug cartels


Up to 100,000 people died in drug-related violence in Mexico in the last 6 years. We might think this has nothing to do with us, but in fact we are all complicit, says Yale professor Rodrigo Canales in this unflinching talk that turns conventional wisdom about drug cartels on its head. The carnage is not about faceless, ignorant goons mindlessly killing each other but is rather the result of some seriously sophisticated brand management.

TEDCity2.0

Robin Nagle: What I discovered in New York City trash


New York City residents produce 11,000 tons of garbage every day. Every day! This astonishing statistic is just one of the reasons Robin Nagle started a research project with the city's Department of Sanitation. She walked the routes, operated mechanical brooms, even drove a garbage truck herself--all so she could answer a simple-sounding but complicated question: who cleans up after us?

Holly Morris: Why stay in Chernobyl? Because it's home.

TEDGlobal 2013

Holly Morris: Why stay in Chernobyl? Because it's home.


Chernobyl was the site of the world's worst nuclear accident and, for the past 27 years, the area around the plant has been known as the Exclusion Zone. And yet, a community of about 200 people live there -- almost all of them elderly women. These proud grandmas defied orders to relocate because their connection to their homeland and to their community are "forces that rival even radiation."

TEDGlobal 2013

Abha Dawesar: Life in the "digital now"


One year ago, Abha Dawesar was living in blacked-out Manhattan post-Sandy, scrounging for power to connect. As a novelist, she was struck by this metaphor: Have our lives now become fixated on the drive to digitally connect, while we miss out on what's real?

Mariana Mazzucato: Government -- investor, risk-taker, innovator

TEDGlobal 2013

Mariana Mazzucato: Government -- investor, risk-taker, innovator


Why doesn’t the government just get out of the way and let the private sector -- the “real revolutionaries” -- innovate? It’s rhetoric you hear everywhere, and Mariana Mazzucato wants to dispel it. In an energetic talk, she shows how the state -- which many see as a slow, hunkering behemoth -- is really one of our most exciting risk-takers and market-shapers.

Xavier Vilalta: Architecture at home in its community

TEDGlobal 2013

Xavier Vilalta: Architecture at home in its community


When TED Fellow Xavier Vilalta was commissioned to create a multistory shopping mall in Addis Ababa, he panicked. Other centers represented everything he hated about contemporary architecture: wasteful, glass towers requiring tons of energy whose design had absolutely nothing to do with Africa. In this charming talk, Vilalta shows how he champions an alternative approach: to harness nature, reference design tradition and create beautiful, modern, iconic buildings fit for a community.

TEDxCERN

Gian Giudice: Why our universe might exist on a knife-edge


The biggest surprise of discovering the Higgs boson? That there were no surprises. Gian Giudice talks us through a problem in theoretical physics: what if the Higgs field exists in an ultra-dense state that could mean the collapse of all atomic matter? With wit and charm, Giudice outlines a grim fate -- and why we shouldn't start worrying just yet.

Parul Sehgal: An ode to envy

TEDSalon NY2013

Parul Sehgal: An ode to envy


What is jealousy? What drives it, and why do we secretly love it? No study has ever been able to capture its “loneliness, longevity, grim thrill” -- that is, says Parul Sehgal, except for fiction. In an eloquent meditation she scours pages from literature to show how jealousy is not so different from a quest for knowledge.

Amanda Bennett: We need a heroic narrative for death


Amanda Bennett and her husband were passionate and full of life all throughout their lives together -- and up until the final days, too. Bennett gives a sweet yet powerful talk on why, for the loved ones of the dying, having hope for a happy ending shouldn't warrant a diagnosis of "denial." She calls for a more heroic narrative for death -- to match the ones we have in life.

TEDGlobal 2013

Molly Stevens: A new way to grow bone


What does it take to regrow bone in mass quantities? Typical bone regeneration -- wherein bone is taken from a patient’s hip and grafted onto damaged bone elsewhere in the body -- is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone’s innate ability to regenerate and produces vast quantities of bone tissue painlessly.

Jeff Speck: The walkable city

TEDGlobal 2013

Dambisa Moyo: Is China the new idol for emerging economies?


The developed world holds up the ideals of capitalism, democracy and political rights for all. Those in emerging markets often don't have that luxury. In this powerful talk, economist Dambisa Moyo makes the case that the west can't afford to rest on its laurels and imagine others will blindly follow. Instead, a different model, embodied by China, is increasingly appealing. A call for open-minded political and economic cooperation in the name of transforming the world.

TEDMED 2013

Gary Slutkin: Let's treat violence like a contagious disease


Physician Gary Slutkin spent a decade fighting tuberculosis, cholera and AIDS epidemics in Africa. When he returned to the United States, he thought he'd escape brutal epidemic deaths. But then he began to look more carefully at gun violence, noting that its spread followed the patterns of infectious diseases. A mind-flipping look at a problem that too many communities have accepted as a given. We've reversed the impact of so many diseases, says Slutkin, and we can do the same with violence. (Filmed at TEDMED.)

TEDGlobal 2013

Michael Porter: Why business can be good at solving social problems


Why do we turn to nonprofits, NGOs and governments to solve society's biggest problems? Michael Porter admits he's biased, as a business school professor, but he wants you to hear his case for letting business try to solve massive problems like climate change and access to water. Why? Because when business solves a problem, it makes a profit -- which lets that solution grow.

Michael Sandel: Why we shouldn't trust markets with our civic life

TEDGlobal 2013

Michael Sandel: Why we shouldn't trust markets with our civic life


In the past three decades, says Michael Sandel, the US has drifted from a market economy to a market society; it's fair to say that an American's experience of shared civic life depends on how much money they have. (Three key examples: access to education, access to justice, political influence.) In a talk and audience discussion, Sandel asks us to think honestly on this question: In our current democracy, is too much for sale?

Journalist Jason Pontin looks closely at the challenges we face to using technology effectively ... for problems that really matter.

Kelli Swazey: Life that doesn't end with death

TEDMED 2013

Kelli Swazey: Life that doesn't end with death


In Tana Toraja, weddings and births aren’t the social gatherings that knit society together. In this part of Indonesia, big, raucous funerals form the center of social life. Anthropologist Kelli Swazey takes a look at this culture, in which the bodies of dead relatives are cared for even years after they have passed. While it sounds strange to Western sensibilities, she says, this could actually be a truer reflection of the fact that relationships with loved ones don’t simply end when breathing does.
