We have no ways to directly observe molecules and what they do -- but Drew Berry wants to change that. He demos his scientifically accurate (and entertaining!) animations that help researchers see unseeable processes within our own cells.

Juan Enriquez challenges our definition of bioenergy. Oil, coal, gas and other hydrocarbons are not chemical but biological products, based on plant matter -- and thus, growable. Our whole approach to fuel, he argues, needs to change.

What if you could take a smell selfie, a smelfie? What if you had a lipstick that caused plants to grow where you kiss? Ani Liu explores the intersection of technology and sensory perception, and her work is wedged somewhere between science, design and art. In this swift, smart talk, she shares dreams, wonderings and experiments, asking: What ha...

Natsai Audrey Chieza is a designer on a mission -- to reduce pollution in the fashion industry while creating amazing new things to wear. In her lab, she noticed that the bacteria Streptomyces coelicolor makes a striking red-purple pigment, and now she's using it to develop bold, color-fast fabric dye that cuts down on water waste and chemical r...

How can humans be so compassionate and altruistic -- and also so brutal and violent? To understand why we do what we do, neuroscientist Robert Sapolsky looks at extreme context, examining actions on timescales from seconds to millions of years before they occurred. In this fascinating talk, he shares his cutting edge research into the biology th...

How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called "spooky action at a distance" helps birds navigate, and quantum effects might explain the origin of life itself.

Designer and architect Neri Oxman is leading the search for ways in which digital fabrication technologies can interact with the biological world. Working at the intersection of computational design, additive manufacturing, materials engineering and synthetic biology, her lab is pioneering a new age of symbiosis between microorganisms, our bodie...

How exactly does gender work? It's not just about our chromosomes, says biologist Karissa Sanbonmatsu. In a visionary talk, she shares new discoveries from epigenetics, the emerging study of how DNA activity can permanently change based on social factors like trauma or diet. Learn how life experiences shape the way genes are expressed -- and wha...

Science is about discovering the wonders of how our world works. From physics to biology to neuroscience, channel your inner Mr. Wizard as you watch these talks.

Satisfy your curiosity on a cellular level with these talks that highlight the ways biology can be molded in the hands of the average, yet curious citizen.

In the early 1990s, a scandal rocked evolutionary biology: scientists discovered that songbirds -- once thought to be strictly monogamous -- engaged in what's politely called "extra-pair copulation." In this unforgettable biology lesson on animal infidelity, TED Fellow Danielle N. Lee shows how she uses hip-hop to teach science, leading the crow...

Physicist Jim Al-Khalili and co-author Johnjoe McFadden, a biologist, explore the far edges of quantum biology in their book "Life on the Edge."

Most people are irritated by the buzzing of a fly's wings. But biologist Michael Dickinson views the sound with a deep sense of wonder.

The world-changing promise of synthetic biology and gene editing has a dark side. In this far-seeing talk, author and entrepreneur Rob Reid reviews the risks of a world where more and more people have access to the tools and tech needed to create a doomsday bug that could wipe out humanity -- and suggests that it's time to take this danger serio...

Jonathan Eisen studies the ecology and evolution of microbial communities -- and their co-evolution with their hosts.

Blue whales are the largest animals on the planet, but what helps them grow to the length of a basketball court? Asha de Vos explains why the size of krill make them the ideal food for the blue whale -- it's as if the blue whale was made to eat krill (and krill was made to be eaten by the blue whale). [Directed by Cognitive Media, narrated by As...

Auke Ijspeert works at the intersection of robotics, biology and computational neuroscience.

Geraldine Hamilton builds organs and body parts on a chip -- to test new, custom cures.

Savage-Rumbaugh's work with bonobo apes, which can understand spoken language and learn tasks by watching, forces the audience to rethink how much of what a species can do is determined by biology -- and how much by cultural exposure.

John Bohannon is a scientist and writer who runs the annual Dance Your Ph.D. contest.

Drew Berry creates stunning and scientifically accurate animations to illustrate how the molecules in our cell move and interact.

Dedicated to increasing awareness about Northern Indian Ocean blue whales, Asha de Vos is also committed to inspiring the next generation of marine biologists.

Simon Berrow is a marine biologist dedicated to studying and preserving the basking shark.

Dermatologist Richard Weller wants to know: Why are Scots so sick?

Mohamed Hijri studies arbuscular mycorrhizal fungi (AMF), seeking to understand the structure, evolution and reproduction of these organisms, which form a symbiotic relationship with plant roots.

Written by the educators who created The Deep Ocean, a brief look at the key facts, tough questions and big ideas in their field. Begin this TED Study with a fascinating read that gives context and clarity to the material.

Neurologist and author Oliver Sacks brings our attention to Charles Bonnet syndrome -- when visually impaired people experience lucid hallucinations. He describes the experiences of his patients in heartwarming detail and walks us through the biology of this under-reported phenomenon.

Brazilian-born biologist Juliana Machado Ferreira wants, simply, to save the world one bird at a time. She is a TED Senior Fellow.

Amy O'Toole is a 12-year-old student who helped run a science experiment inspired by Beau Lotto's participative science approach. At age 10 she became one of the youngest people ever to publish a peer-reviewed science paper.

Genitals are the fastest-evolving organs in the animal kingdom. But why is this so? And what's the point of having decorative private parts? Menno Schilthuizen explains how the evolutionary biology of nature's nether regions uncovers a hidden world of seduction, conflict, and rivalry. [Directed by Mette Ilene Holmriis, narrated by Adrian Dannatt...
