Now Playing: TED Radio Hour

Manipulation
We think we're the ones who control what we see, read, think and remember. But is that true? Who decides? And who should decide? This hour, TED speakers reveal just how easily we can be manipulated. Guests include design ethicist Tristan Harris, MSNBC host Ali Velshi, psychologist Elizabeth Loftus, and neuroscientist Steve Ramirez.

#443 Batteries
This week on Science for the People we take a deep dive into modern batteries: how they work now and how they might work in the future. We speak with Gerbrand Ceder from UC Berkeley, about the most commonly used batteries today, how they work, and how they could work better. And we talk with Kathryn Toghill, electrochemist from Lancaster University, about redox flow batteries and how they could help make our power grids more sustainable.
