How we can turn the cold of outer space into a renewable resource | Aaswath Raman

What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he's developing to harness "night-sky cooling" -- a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it -- which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.

Sunday Pick: An Indigenous Mixtape from Lima, Peru

Sunday Pick: An Indigenous Mixtape from Lima, Peru

Meet Liberato Kani, a hip hop artist in Lima, Peru—or as he says, “the Andean Bronx”. At his concerts, a typical call and response you hear is "Quechua es resistencia": Quechua is resistance. Though Quechua is spoken by nearly ten million people, Peru's native language is at risk of dying off because of anti-indigenous prejudice. Liberato and other musicians like Renata Flores are here to save it—and restore a country's pride while they're at it. Want to talk more about the show? Share your favorite artist from this episode with host Saleem Reshamwala (@Kidethnic) on Twitter. This episode features music and interviews from Liberato Kani, Renata Flores, Kayfex, and Uchpa's guitarist and songwriter Marcos Maizel. Listen to more from these artists on TED's Spotify playlist, "Quechua es Resistencia.”Pindrop is produced by Jesse Baker and Eric Nuzum of Magnificent Noise for TED.

The hidden forces behind your food choices | Sarah Lake

What we eat is less about what we choose and more about what’s offered to us, says food and climate expert Sarah Lake. Unpacking how governments and companies have driven up meat consumption in the US through extensive marketing, she explains how we could employ these same forces to incentivize plant-based eating — for the sake of the planet, public health and global food security.
