Could the key to a sustainable food system already be growing in the world’s farms? Plant scientist Giles E.D. Oldroyd explores how a special quirk of soybean plants allows them to naturally partner with networks of fungi and bacteria to access essential nutrients in the air and soil — eliminating the need for synthetic fertilizers. He shows how harnessing these microscopic powerhouses could help scientists rewire crops to make their own fertilizer, reducing pollution, increasing yields and improving livelihoods for smallholder farmers. After the talk, Sherrell discuss the ways three companies are developing alternatives to synthetic fertilizers and how their efforts contribute to sustainable agriculture.

He imagines a world where anyone can create a Hollywood film, receive personalized education or communicate via hyper-realistic avatars — all in the time it takes to read a book.

Moore’s Law states that every 1 to 2 years the number of transistors that can fit on a given size computer chip will double. Thanks to this law, chips have gotten smaller, faster, more efficient, and cheaper. But today, there are four key problems that trip up this trend, potentially ending Moore’s Law and fundamentally changing how computing progresses. Sajan Saini and George Zaidan investigate. [Directed by Jeff Le Bars, JetPropulsion, narrated by Adrian Dannatt, music by Stephen LaRosa].
