To eliminate waste, we need to rediscover thrift | Andrew Dent

Could smartphones and cameras be our most powerful weapon for social justice? Through her organization Witness, Yvette Alberdingk Thijm is developing strategies and technologies to help activists use video to protect and defend human rights. She shares stories of the growing power of distant witnesses -- and a call to use the powerful tools at our disposal to capture incidents of injustice. Hosted on Acast.

Joel Jackson wants to reimagine transportation around the needs of the African consumer. He's designed an SUV that's rugged enough for long stretches of uneven terrain and affordable enough to be within reach of those who need it most. Learn more about the challenges of mobility and manufacturing in Africa -- and what a localized motor industry could mean for the future of the continent. Hosted on Acast.

China is a huge laboratory of innovation, says retail expert Angela Wang, and in this lab, everything takes place on people's phones. Five hundred million Chinese consumers -- the equivalent of the combined populations of the US, UK and Germany -- regularly make purchases via mobile platforms, even in brick-and-mortar stores. What will this transformation mean for the future of shopping? Learn more about the new business-as-usual, where everything is ultra-convenient, ultra-flexible and ultra-social. Hosted on Acast.

Since the widespread use of antibiotics began in the 1940s, we've tried to develop new drugs faster than bacteria can evolve -- but this strategy isn't working. Drug-resistant bacteria known as superbugs killed nearly 700,000 people last year, and by 2050 that number could be 10 million -- more than cancer kills each year. Can physics help? In a talk from the frontiers of science, radiation scientist David Brenner shares his work studying a potentially life-saving weapon: a wavelength of ultraviolet light known as far-UVC, which can kill superbugs safely, without penetrating our skin. Followed by a Q&A with TED Curator Chris Anderson. Hosted on Acast. See acast.com/privacy for more information.

Africa needs engineers, but its engineering students often end up working at auditing firms and banks. Why? Kamau Gachigi suspects it's because they don't have the spaces and materials needed to test their ideas and start businesses. To solve this problem, Gachigi started Gearbox, a makerspace and hardware accelerator that provides a rapid prototyping environment for both professionals and people with no formal engineering background. In this forward-thinking talk, he shares some of the extraordinary projects and innovations coming out of his Kenyan fab lab. Hosted on Acast. See acast.com/privacy for more information.

Space physicist Miho Janvier studies solar storms: giant clouds of particles that escape from the Sun and can disrupt life on Earth (while also producing amazing auroras). How do you study the atmosphere on the Sun, which burns at temperatures of up to around 10 million degrees Kelvin? With math! Join the TED Fellow as she shares her work trying to better understand how the Sun affects us here on Earth. Hosted on Acast. See acast.com/privacy for more information.

Joan Blades and John Gable want you to make friends with people who vote differently than you do. A pair of political opposites, the two longtime pals know the value of engaging in honest conversations with people you don't immediately agree with. Join them as they explain how to bridge the gaps in understanding between people on opposite sides of the political spectrum -- and create opportunities for mutual listening and consideration (and, maybe, lasting friendships.)

How will we live elsewhere in the galaxy? On Earth, natural resources for creating structures are abundant, but sending these materials up with us to the Moon or Mars is clunky and cost-prohibitive. Enter architect Xavier De Kestelier, who has a radical plan to use robots and space dust to 3D print our interplanetary homes. Learn more about the emerging field of space architecture with this fascinating talk about the (potentially) not-too-distant future. Hosted on Acast. See acast.com/privacy for more information.
