Hannah Brencher's mother always wrote her letters. So when she felt herself bottom into depression after college, she did what felt natural -- she wrote love letters and left them for strangers to find. The act has become a global initiative, The World Needs More Love Letters, which rushes handwritten letters to those in need of a boost. Hosted on Acast. See acast.com/privacy for more information.

Consider the following scenario: a highly infectious, sometimes deadly respiratory virus infects humans for the first time. It spreads rapidly worldwide, and the WHO declares a pandemic. The death toll starts to rise and everyone is asking the same question: when will the pandemic end? Alex Rosenthal details the three main strategies governments can use to contain and end a pandemic. [Directed by Visorama, narrated by Jack Cutmore-Scott, music by Bamm Bamm Wolfgang]. Hosted on Acast. See acast.com/privacy for more information.

At age 16, journalist and filmmaker Jose Antonio Vargas found out he was in the United States illegally. Since then, he’s been thinking deeply about immigration and what it means to be a US citizen -- whether it’s by birth, law or otherwise. In this powerful talk, Vargas calls for a shift in how we think about citizenship and encourages us all to reconsider our personal histories by answering three questions: Where did you come from? How did you get here? Who paid? Hosted on Acast. See acast.com/privacy for more information.

We have archives of films, newspapers, even seeds -- what if we could make one for the entire surface of the earth? Drawing on his experience mapping an ancient city in the Honduran jungle, archaeologist Chris Fisher makes the case for scanning the whole planet with LiDAR -- a technology that uses lasers shot from an airplane to map the ground -- in order to preserve our cultural and ecological heritage.

"In a world" -- our world -- movie trailers have undergone a massive evolution. The booming voice-of-God narration of the '80s and '90s has been silenced in favor of boojes and bwaas.

As kids, we all get advice from parents and teachers that seems strange, even confusing. This was crystallized one night for a young Clint Smith, who was playing with water guns in a dark parking lot with his white friends. In a heartfelt piece, the poet paints the scene of his father's furious and fearful response. Hosted on Acast. See acast.com/privacy for more information.

On this episode of ZigZag, host Manoush Zomorodi is joined by Eric Ries, who went from writing Silicon Valley's bible to building a stock market for social justice. Together, they examine why quarterly earnings reports cause anti-social behavior and how a new stock exchange in the US might present a systemic solution. As Eric says, this "will serve as inspiration to a new generation of civic entrepreneurs who will say: We don't have to take the institutions of our society as a given. We could try to build new and better ones." ZigZag, the business show about being human, is now a member of the TED family of podcasts. Listen or subscribe wherever you get your podcasts.

Nearly 400 years ago, a tiny town in Germany made a bargain with God: spare its people from the Black Plague and we'll put on a play in your honor... forever. And it worked! Now every decade, the entire town comes together to stage the play, drawing massive crowds to one of the largest religious spectacles in the world. But problematic parts of the play have been challenged, and tensions rise when a new voice tries to update a 2,000-year-old story with help from some unexpected allies. (Audio only) Hosted on Acast.

You use your brain's executive function every day -- it's how you do things like pay attention, plan ahead and control impulses. Can you improve it to change for the better? With highlights from her research on child development, cognitive scientist Sabine Doebel explores the factors that affect executive function -- and how you can use it to break bad habits and achieve your goals.

Our biases can be dangerous, even deadly — as we've seen in the cases of Michael Brown in Ferguson, Missouri, and Eric Garner, in Staten Island, New York. Diversity advocate Vernā Myers looks closely at some of the subconscious attitudes we hold toward out-groups. She makes a plea to all people: Acknowledge your biases. Then move toward, not away from, the groups that make you uncomfortable. In a funny, impassioned, important talk, she shows us how. Hosted on Acast. See acast.com/privacy for more information.

Things are pretty shocking out there right now -- record-breaking storms, deadly terror attacks, thousands of migrants disappearing beneath the waves and openly supremacist movements rising. Are we responding with the urgency that these overlapping crises demand from us? Journalist and activist Naomi Klein studies how governments use large-scale shocks to push societies backward. She shares a few propositions from "The Leap" -- a manifesto she wrote alongside indigenous elders, climate change activists, union leaders and others from different backgrounds -- which envisions a world after we've already made the transition to a clean economy and a much fairer society. "The shocking events that fill us with dread today can transform us, and they can transform the world for the better," Klein says. "But first we need to picture the world that we're fighting for. And we have to dream it up together." Hosted on Acast. See acast.com/privacy for more information.

Far-UVC light is a type of ultraviolet light that kills microbes and viruses and, crucially, seems to be safe to use around humans. Radiation scientist David Brenner describes how we could use this light to stop the spread of SARS-CoV-2, the virus responsible for COVID-19, in hospitals, nursing homes, trains and other public indoor spaces -- paving the way for a potentially game-changing tool in the fight against the coronavirus pandemic.

What does Kendrick Lamar have in common with Disney's "Moana"? They recognize our common humanity and show us how to love ourselves and one another, says writer and educator Chloé Valdary. She shares how she uses pop culture to help people develop resilience and advance social change -- and explains why cultivating love is the key to connection, healing and moving forward together.

Crisis interventions often focus on a single aspect of a big, complicated problem, failing to address the broader social and economic context. Kwame Owusu-Kesse describes how the Harlem Children’s Zone is taking a more holistic approach to the pandemic, weaving together a network of services to help communities recover and rebuild. Learn more about their comprehensive COVID-19 relief and recovery response focused on five primary areas of need -- and their plans to scale it across the US. (This ambitious plan is a part of the Audacious Project, TED’s initiative to inspire and fund global change.) Hosted on Acast. See acast.com/privacy for more information.

On July 20, 2012, a mass shooting in a movie theater of Aurora, Colorado left the town, and the nation, reeling. To many -- including Tom Teves, who lost his son in the tragedy -- the news coverage that followed focused on all the wrong things. Why did the reporting overwhelmingly fixate on the shooter rather than the lives of the victims or the heroic efforts of first responders? With urgency and measure, Teves calls for media attention that acts in the interest of the public (instead of profit) by revoking what shooters want most: infamy. Hosted on Acast.
