TED Talks Science and Medicine TED Talks

Conventional vaccine testing is a slow, years-long process. As thousands of people continue to die each day from COVID-19, bioethicist Nir Eyal proposes a radical idea that could dramatically accelerate the vaccine development timeline: "human challenge trials," in which scientists would deliberately expose volunteers to the virus to more quickly determine a vaccine's efficacy. (This virtual conversation, hosted by head of TED Chris Anderson, was recorded June 15, 2020.)

At the intersection of precision medicine and vaccinology lies a revolutionary scientific pursuit: personalized vaccines. Infectious disease specialist Ofer Levy introduces this promising medical approach, in which tailored inoculations will enable effective immunization of the most vulnerable among us, including the young and elderly, and shares how we're now venturing into a new era of sustaining and supporting human life. (This talk contains graphic medical imagery.)

Investigative journalist Katherine Eban set out to report on a seemingly straightforward question: Are generic drugs really identical to their brand-name counterparts? The answer sparked a decade of interviews, meetings with whistleblowers, on-the-ground reporting across four continents and digging into confidential FDA documents. In this alarming talk, she takes us inside overseas manufacturing plants and exposes the fraud behind many low-cost generic medicines.

Earth, humanity and nature are inextricably interconnected. To restore us all back to health, we need to "rewild" the world, says environmental activist Kristine Tompkins. Tracing her life from Patagonia CEO to passionate conservationist, she shares how she has helped to establish national parks across millions of acres of land (and sea) in South America -- and discusses the critical role we all have to play to heal the planet. "We have a common destiny," she says. "We can flourish or we can suffer, but we're going to be doing it together."

How do doctors in the emergency room stay calm and focused amidst the chaos? Drawing on years of experience, ER doctor Darria Long shares a straightforward framework to help you take back control and feel less overwhelmed when life starts to get "crazy busy."

Some biological structures are so small that scientists can't see them with even the most powerful microscopes. That's where molecular animator and TED Fellow Janet Iwasa gets creative. Explore vast, unseen molecular worlds as she shares mesmerizing animations that imagine how they might work.
