SpaceX's plan to fly you across the globe in 30 minutes | Gwynne Shotwell

What's up at SpaceX? Engineer Gwynne Shotwell was employee number seven at Elon Musk's pioneering aerospace company and is now its president. In conversation with TED curator Chris Anderson, she discusses SpaceX's race to put people into orbit and the organization's next big project, the BFR (ask her what it stands for). The new giant rocket is designed to take humanity to Mars -- but it has another potential use: space travel for earthlings.

A Parkland teacher's homework for us all | Diane Wolk-Rogers

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."

Why it's worth listening to people you disagree with | Zachary R. Wood

We get stronger, not weaker, by engaging with ideas and people we disagree with, says Zachary R. Wood. In an important talk about finding common ground, Wood makes the case that we can build empathy and gain understanding by engaging tactfully and thoughtfully with controversial ideas and unfamiliar perspectives. "Tuning out opposing viewpoints doesn't make them go away," Wood says. "To achieve progress in the face of adversity, we need a genuine commitment to gaining a deeper understanding of humanity."

The "dead zone" of the Gulf of Mexico | Nancy Rabalais

Ocean expert Nancy Rabalais tracks the ominously named "dead zone" in the Gulf of Mexico -- where there isn't enough oxygen in the water to support life. The Gulf has the second largest dead zone in the world; on top of killing fish and crustaceans, it's also killing fisheries in these waters. Rabalais tells us about what's causing it -- and how we can reverse its harmful effects and restore one of America's natural treasures.
