Chemical plants create many of the materials found in everyday items, from the shoes you wear to the car you drive to the cell phone in your pocket. But the massive carbon footprint from chemical manufacturing is leading to climate breakdown. Sustainable engineering researcher Miguel A. Modestino presents his team’s pioneering work on electrochemical engineering -- the design and implementation of new chemical reactions that source their energy directly from electricity, as opposed to fossil fuels -- and explains how it could reduce the world’s dependence on oil and gas, protect its natural treasures and keep the economy humming.

Digital creator Dylan Marron has racked up millions of views for projects like "Every Single Word" and "Sitting in Bathrooms With Trans People" -- but he's found that the flip side of success online is internet hate. Over time, he's developed an unexpected coping mechanism: calling the people who leave him insensitive comments and asking a simple question: "Why did you write that?" In a thoughtful talk about how we interact online, Marron explains how sometimes the most subversive thing you can do is actually speak with people you disagree with, not simply at them. Listen to Dylan's podcast, "Conversations With People Who Hate Me", wherever you get your podcasts. Hosted on Acast. See acast.com/privacy for more information.

In a mind-blowing talk laden with breakthrough science, he shows how his team figured out how to grow what they call brain "assembloids" -- self-organizing clumps of neural tissue derived from stem cells that have shown the ability to form circuits -- and explains how these miniature parts of the nervous system are bringing us closer to demystifying the brain.

Taking cues from soft robotics and the natural world, conceptual artist Anicka Yi builds lighter-than-air machines that roam and react like autonomous life forms. Her floating “aerobes” inspire us to think about new ways of living with machines -- and to ponder how they could evolve into living creatures. “What if our machines could be more than just our tools, and instead, a new type of companion species?” she asks.

Everyone has the right to a clean environment -- but major disparities exist when it comes to who faces the consequences of pollution. Environmental justice leader Peggy Shepard points to the disproportionate impact that hazardous environmental conditions have on Black, brown and Indigenous communities and challenges us to build a truly equitable future that turns "sacrifice zones" -- where community health is sacrificed for the sake of development -- into "green zones" that redress the legacy of pollution and harmful policies.

Plastics are everywhere -- they're in our favorite electronic devices, they package our food and insulate our homes. Today, the total mass of plastic is twice the total mass of all living organisms on the planet, and it's starting to change the processes that allow the Earth's climate system to work. Plastic pollution researcher Patricia Villarrubia-Gómez breaks down the consequences of producing all of this plastic at every stage, from fossil fuel extraction to the disposal of single-use plastics in landfills and oceans. The first step to breaking free of our plastic problem is admitting we have one. Hosted on Acast. See acast.com/privacy for more information.

On a list of the least funny topics imaginable, the global refugee crisis, border disputes and questions of citizenship are probably close to the top. And yet comedian Maeve Higgins has spent her career finding ways to make jokes about (and make sense of) the ways we draw lines across the globe. She's a stand-up comedian and writer who speaks from the point of view of an Irish immigrant in the United States. In this excerpt from How to Be a Better Human, a TED Audio Collective podcast hosted by Chris Duffy, Maeve talks about ways we can find funny and eye-opening vantage points to look at the realities and borders of the world, our place in it and how imagination and laughter can help us through tough times. We asked Chris to select a book that he thinks explores these topics more deeply, and he selected "There There" by Tommy Orange. Listen for his recommendation and why he thinks it's "like the best action movie and one of the smartest sociological and historical essays paired together." This episode is part of the TED Talks Daily summer book club, a series featuring talks and interviews to inspire your next great read. Hosted on Acast. See acast.com/privacy for more information.
