Each Sunday, TED shares an episode of another podcast we think you'll love, handpicked for you… by us. Today: an episode from TED Tech. From the construction of virtual realities to the internet of things host Sherrell Dorsey guides you through the latest ideas from TED Speakers, uncovering the riveting questions that sit at the intersection of technology and society. What happens when the data-driven capabilities of AI are combined with human creativity and ingenuity? Shining a light on the opportunities this futuristic collaboration could bring to the workplace, AI expert Shervin Khodabandeh shares how to redesign companies so that people and machines can learn from each other. After Shervin's talk, hear from Sherrell on the potential promises (and pitfalls) of AI-work integration. 

When the world's problems have you weary, journalist and science fiction writer Annalee Newitz suggests a good dose of escapist fiction to refresh your perspective. Step into the whimsical world of science fiction, cosplay and "goblincore" to see how fantasy worlds help us reimagine our relationships with our communities and each other — and why the best way to solve your problems may start with escaping them.

What you experience through your senses — sight, smell, hearing, taste and touch — can impact how healthy you are and how long you live, says neurobiologist Christi Gendron. She explores how environmental cues like temperature, light and even just the sight of death have influenced the lifespan of fruit flies, suggesting your everyday perceptions may have direct repercussions on your ability to live a long, healthy life.

As climate change leads to more and more natural disasters, a group of workers is showing up at one site after another to rebuild and repair.

In the beginning of the universe, all was darkness — until the first organisms developed sight, which ushered in an explosion of life, learning and progress. AI pioneer Fei-Fei Li says a similar moment is about to happen for computers and robots. She shows how machines are gaining "spatial intelligence" — the ability to process visual data, make predictions and act upon those predictions — and shares how this could enable AI to interact with humans in the real world.
