After decades of research and billions spent in clinical trials, we still have a problem with cancer drug delivery, says biomedical engineer Elizabeth Wayne. Chemotherapy kills cancer — but it kills the rest of your body, too. Instead of using human design to fight cancer, why not use nature’s? In this quick talk, Wayne explains how her lab is creating nanoparticle treatments that bind to immune cells, your body’s first responders, to precisely target cancer cells without damaging healthy ones.

We’ve all heard that robots are going to take our jobs — but what can we do about it? Innovation expert David Lee says that we should start designing jobs that unlock our hidden talents and passions — the things we spend our weekends doing — to keep us relevant in the age of robotics. “Start asking people what problems they’re inspired to solve and what talents they want to bring to work,” Lee says. “When you invite people to be more, they can amaze us with how much more they can be.”

Known worldwide for her courage and clarity, Christiane Amanpour has spent the past three decades interviewing business, cultural and political leaders who have shaped history. In conversation with TED Curator Chris Anderson, Amanpour discusses fake news, objectivity in journalism, the leadership vacuum in global politics and more, sharing her wisdom along the way. “Be careful where you get information from,” she says. “Unless we are all engaged as global citizens who appreciate the truth, who understand science, empirical evidence and facts, then we are going to be wandering around — to a potential catastrophe.”
