Why do teenagers sometimes make outrageous, risky choices? Do they suddenly become reckless, or are they just going through a natural phase? To find out, Kashfia Rahman -- winner of the Intel International Science and Engineering Fair (and a Harvard freshman) -- designed and conducted an experiment to test how high school students respond to and get used to risk, and how it changes their still-developing brains. What she discovered about risk and decision-making could change how we think about why teens do what they do. Hosted on Acast. See acast.com/privacy for more information.

In a world deeply divided, how do we have hard conversations with nuance, curiosity, respect? Veteran reporter Eve Pearlman introduces "dialogue journalism": a project where journalists go to the heart of social and political divides to support discussions between people who disagree. See what happened when a group that would have never otherwise met -- 25 liberals from California and 25 conservatives from Alabama -- gathered to talk about contentious issues. "Real connection across difference: this is a salve that our democracy sorely needs," Pearlman says. Hosted on Acast. See acast.com/privacy for more information.

Every minute, 20 people are newly displaced by climate change, economic crisis and political instability, according to the UNHCR. How can we help them overcome the barriers to starting new lives? TED Resident Muhammed Idris is leading a team of technologists, researchers and refugees to develop Atar, the first-ever AI-powered virtual advocate that guides displaced people through resettlement, helping restore their rights and dignity. "Getting access to the right resources and information can be the difference between life and death," Idris says. Hosted on Acast. See acast.com/privacy for more information.

Diane Wolk-Rogers teaches history at Marjory Stoneman Douglas High School in Parkland, Florida, site of a horrific school shooting on Valentine's Day 2018. How can we end this senseless violence? In a stirring talk, Wolk-Rogers offers three ways Americans can move forward to create more safety and responsibility around guns -- and invites people to come up with their own answers, too. Above all, she asks us to take a cue from the student activists at her school, survivors whose work for change has moved millions to action. "They shouldn't have to do this on their own," Wolk-Rogers says. "They're asking you to get involved." Hosted on Acast. See acast.com/privacy for more information.

Neuroscientist and pediatrician Kimberly Noble is leading the Baby's First Years study: the first-ever randomized study of how family income changes children's cognitive, emotional and brain development. She wants to find out: Can we help kids in poverty simply by giving families more money? "The brain is not destiny," Noble says. "And if a child's brain can be changed, then anything is possible."
