A new weapon in the fight against superbugs | David Brenner

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.

The next step in nanotechnology | George Tulevski

The next step in nanotechnology | George Tulevski

Nearly every other year the transistors that power silicon computer chip shrink in size by half and double in performance, enabling our devices to become more mobile and accessible. But what happens when these components can't get any smaller? George Tulevski researches the unseen and untapped world of nanomaterials. His current work: developing chemical processes to compel billions of carbon nanotubes to assemble themselves into the patterns needed to build circuits, much the same way natural organisms build intricate, diverse and elegant structures. Could they hold the secret to the next generation of computing?For a chance to give your own TED Talk, fill out the Idea Search Application: ted.com/ideasearch.Interested in learning more about upcoming TED events?
