Neuroengineer Ed Boyden wants to know how the tiny biomolecules in our brains generate emotions, thoughts and feelings -- and he wants to find the molecular changes that lead to disorders like epilepsy and Alzheimer's. Rather than magnify these invisible structures with a microscope, he wondered: What if we physically enlarge them and make them ...

Plants behave in some oddly intelligent ways: fighting predators, maximizing food opportunities ... But can we think of them as actually having a form of intelligence of their own? Italian botanist Stefano Mancuso presents intriguing evidence.

Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he's managed to cure mice of analogs of PTSD and certain forms of blindness. On the horizon: neural prosthetics. Session host Juan ...

Say hello to the decentralized economy -- the blockchain is about to change everything. In this lucid explainer of the complex (and confusing) technology, Bettina Warburg describes how the blockchain will eliminate the need for centralized institutions like banks or governments to facilitate trade, evolving age-old models of commerce and finance...

John Bidden and his band return to the TED@UPS stage with an upbeat, reggae-inspired original performance of "Not About Me" that is sure to get you dancing.

How does a computer work? The critical components of a computer are the peripherals (including the mouse), the input/output subsystem (which controls what and how much information comes in and out), and the central processing unit (the brains), as well as human-written programs and memory. Bettina Bair walks us through the steps your computer ta...

What should a community do with its unused land? Plant food, of course. With energy and humor, Pam Warhurst tells at the TEDSalon the story of how she and a growing team of volunteers came together to turn plots of unused land into communal vegetable gardens, and to change the narrative of food in their community.

Should a cauliflower be valued and preserved like the Mona Lisa? What would it mean to us if we lost the cauliflower as a species? The world has experienced a 75 percent decrease in horticultural diversity in the past 150 years. Botanist and educator Esther Meduna explains why this is a problem and how the seed libraries popping up worldwide are...

What aspects of religion should atheists (respectfully) adopt? Alain de Botton suggests a "religion for atheists" -- call it Atheism 2.0 -- that incorporates religious forms and traditions to satisfy our human need for connection, ritual and transcendence.

Pam Warhurst cofounded Incredible Edible, an initiative in Todmorden, England dedicated to growing food locally by planting on unused land throughout the community.

Green, leafy, often delicious: Plants are all around us and make the ecosystem work. Hear from gardeners, vegetarians, designers and conservationists on the wonderful world of plants and vegetables.

Pollen goes unnoticed by most of us, except when hay fever strikes. But microscopes reveal it comes in stunning colors and shapes -- and travels remarkably well. Jonathan Drori gives an up-close glimpse of these fascinating flecks of plant courtship.

If you were a jackrabbit in the desert, you'd be glad to stumble across a cactus: the flesh of these plants is a water source for many animals. Known for their spines and succulent stems, cacti of all shapes and sizes have evolved to not just survive, but thrive, in some of the harshest desert climates on Earth. So how do they do it? Lucas C. Ma...

Alain de Botton examines our ideas of success and failure -- and questions the assumptions underlying these two judgments. Is success always earned? Is failure? He makes an eloquent, witty case to move beyond snobbery to find true pleasure in our work.

Trees talk, flowers build elaborate traps and some plants can even come back from the dead. Skeptical? These fascinating talks may just grow on you.

You’ve heard of ‘do it yourself,’ but what about ‘grow it yourself?’ Enjoy these quirky talks full of possibilities.

In this visually dazzling talk, Jonathan Drori shows the extraordinary ways flowering plants -- over a quarter million species -- have evolved to attract insects to spread their pollen: growing 'landing-strips' to guide the insects in, shining in ultraviolet, building elaborate traps, and even mimicking other insects in heat.

Bugs are one of nature's wonders. These insect-obsessed speakers talk about how ants form societies, how bees pollinate flowers, and how termites can be quite ... tasty.

After Robert Lang's talk on origami at TED2008, Bruno Bowden stepped onstage with a challenge -- he would fold one of Lang's astonishingly complicated origami figures, blindfolded, in under 2 minutes. He's accompanied by the cellist Rufus Cappadocia.

Ed Boyden is a professor of biological engineering and brain and cognitive sciences at the MIT Media Lab and the MIT McGovern Institute.

Resource inequality is one of our greatest challenges, but it's not unique to humans. Like us, mycorrhizal fungi that live in plant and tree roots strategically trade, steal and withhold resources, displaying remarkable parallels to humans in their capacity to be opportunistic (and sometimes ruthless) -- all in the absence of cognition. In a min...

Great life advice for the moment after you throw your mortarboard in the air.

Bettina Warburg is a blockchain researcher, entrepreneur and educator. A political scientist by training, she has a deep passion for the intersection of politics and technology.

An engineer with Google (he helped build Google Earth), Bruno Bowden is also an enthusiastic folder of paper.

Working at the intersection of art and science, Nirupa Rao seeks to bring alive the magic of the plant kingdom.

There's a farming crisis no one is talking about: The world is running out of phosphorus, an essential element that's a key component of DNA and the basis of cellular communication. As biologist Mohamed Hijri shows, all roads of this crisis lead back to how we farm -- with chemical fertilizers chock-full of the element, which plants are not effi...

What defines success -- and what is a failure, exactly? Readjust your expectations with these novel, refreshing perspectives on what it means to “win” and “lose”.

Artist Sam Van Aken shares the breathtaking work behind the "Tree of 40 Fruit," an ongoing series of hybridized fruit trees that grow 40 different varieties of peaches, plums, apricots, nectarines and cherries -- all on the same tree. What began as an art project to showcase beautiful, multi-hued blossoms has become a living archive of rare heir...
