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. Hosted on Acast. See acast.com/privacy for more information.

A printable, flexible, organic solar cell | Hannah Bürckstümmer
Unlike the solar cells you're used to seeing, organic photovoltaics are made of compounds that are dissolved in ink and can be printed and molded using simple techniques. The result is a low-weight, flexible, semi-transparent film that turns the energy of the sun into electricity. Hannah Bürckstümmer shows us how they're made -- and how could change the way we power the world. Hosted on Acast. See acast.com/privacy for more information.

What's missing in the global debate over refugees | Yasin Kakande
In the ongoing debate over refugees, we hear from everyone -- from politicians who pledge border controls to citizens who fear they'll lose their jobs -- everyone, that is, except migrants themselves. Why are they coming? Journalist and TED Fellow Yasin Kakande explains what compelled him and many others to flee their homelands, urging a more open discussion and a new perspective. Because humanity's story, he reminds us, is a story of migration: "There are no restrictions that could ever be so rigorous to stop the wave of migration that has determined our human history," he says.
