Stuart Firestein The pursuit of ignorance
What does real scientific work look like? As neuroscientist Stuart Firestein jokes: It looks a lot less like the scientific method and a lot more like "farting around ... in the dark." In this witty talk, Firestein gets to the heart of science as it is really practiced and suggests that we should value what we don't know — or "high-quality ignorance" — just as much as what we know.
Naomi Oreskes Why we should trust scientists
Many of the world's biggest problems require asking questions of scientists — but why should we believe what they say?

Uri Alon Why science demands a leap into the unknown
While studying for his PhD in physics, Uri Alon thought he was a failure because all his research paths led to dead ends. But, with the help of improv theater, he came to realize that there could be joy in getting lost. A call for scientists to stop thinking of research as a direct line from question to answer, but as something more creative. It's a message that will resonate, no matter what your field.
Vanessa Ruiz The spellbinding art of human anatomy
Vanessa Ruiz takes us on an illustrated journey of human anatomical art over the centuries, sharing captivating images that bring this visual science — and the contemporary artists inspired by it — to life. "Anatomical art has the power to reach far beyond the pages of a medical textbook," she says, "connecting our innermost selves with our bodies through art."
Andrew Pelling This scientist makes ears out of apples
TED Fellow Andrew Pelling is a biohacker, and nature is his hardware. His favorite materials are the simplest ones (and oftentimes he finds them in the garbage). Building on the cellulose structure that gives an apple its shape, he "grows" lifelike human ears, pioneering a process that might someday be used to repair body parts safely and cheaply. And he has some even wilder ideas to share ... "What I'm really curious about is if one day it will be possible to repair, rebuild and augment our own bodies with stuff we make in the kitchen," he says.
Laura Snyder The Philosophical Breakfast Club
In 1812, four men at Cambridge University met for breakfast. What began as an impassioned meal grew into a new scientific revolution, in which these men — who called themselves “natural philosophers” until they later coined “scientist” — introduced four major principles into scientific inquiry. Historian and philosopher Laura Snyder tells their intriguing story.
