How to see (and stop) deforestation from space | Tasso Azevedo

How to see (and stop) deforestation from space | Tasso Azevedo

Nearly 20 trees are cut down every second in the Amazon rainforest, as authorities struggle to monitor millions of acres and stop illegal clear-cutting. But land reformer Tasso Azevedo and his team at MapBiomas have changed the game, transforming satellite imagery into precise, real-time maps that make every clear-cut visible — and every actor accountable. Learn how they're helping slash deforestation in the Amazon, proving that transparency is a forest's strongest defense. (This ambitious idea is part of The Audacious Project, TED’s initiative to inspire and fund global change.)

To solve old problems, study new species | Alejandro Sánchez Alvarado

To solve old problems, study new species | Alejandro Sánchez Alvarado

Nature is wonderfully abundant, diverse and mysterious -- but biological research today tends to focus on only seven species, including rats, chickens, fruit flies and us. We're studying an astonishingly narrow sliver of life, says biologist Alejandro Sánchez Alvarado, and hoping it'll be enough to solve the oldest, most challenging problems in science, like cancer. In this visually captivating talk, Alvarado calls on us to interrogate the unknown and shows us the remarkable discoveries that surface when we do. Hosted on Acast.

The next step in nanotechnology | George Tulevski

The next step in nanotechnology | George Tulevski

Nearly every other year the transistors that power silicon computer chip shrink in size by half and double in performance, enabling our devices to become more mobile and accessible. But what happens when these components can't get any smaller? George Tulevski researches the unseen and untapped world of nanomaterials. His current work: developing chemical processes to compel billions of carbon nanotubes to assemble themselves into the patterns needed to build circuits, much the same way natural organisms build intricate, diverse and elegant structures. Could they hold the secret to the next generation of computing? Hosted on Acast. See acast.com/privacy for more information.
