The words we use to describe our emotions affect how we feel, says historian Tiffany Watt Smith, and they've often changed (sometimes very dramatically) in response to new cultural expectations and ideas.

In this fascinating talk about the history of emotions, learn more about how the language we use to describe how we feel continues to evolve -- and pick up some new words used in different cultures to capture those fleeting feelings in words.

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.
