With candor and cunning, sex historian Kate Lister chronicles the curious journey of an ancient, honest word with innocent origins and a now-scandalous connotation in this uproarious love letter to etymology, queens, cows and all things "cunt."

DNA isn't the only builder in the biological world -- there's also a mysterious bioelectric layer directing cells to work together to grow organs, systems and bodies, says biologist Michael Levin. Sharing unforgettable and groundbreaking footage of two-headed worms, he introduces us to xenobots -- the world's first living robots, created in his lab by cracking the electrical code of cells -- and discusses what this discovery may mean for the future of medicine, the environment and even life itself. (This conversation, hosted by TED's Chris Anderson, was recorded June 2020.)

Dictionaries and grammar "rules" don't have the final word on language -- and believing they do can harm more than help, especially for the trans community. Sociolinguist Archie Crowley deconstructs three common myths around language, demonstrating how it's a fluid system that naturally evolves in the direction of inclusion.

Farmers stand at the center of the world, says Andrew Youn, cofounder of One Acre Fund, an agricultural organization that's empowering sub-Saharan farm families with the loans, seeds, fertilizer and training needed to increase crop yields and end hunger. Meet Therese Niyonsaba, a Rwandan farmer who shares how the program helped her family prosper, and learn more about One Acre Fund's goal to lead a farmer-focused green revolution and reach 6.8 million families by 2026. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

From hours-long lines and limited polling locations to confusing and discriminatory registration policies, why is it so hard to vote in the US? Voting rights expert Amber McReynolds offers a proven alternative: a new process, already happening in parts of the country, that could bring accountability, transparency and equity to the outdated and sputtering system that American democracy currently relies on.

The only thing as powerful as our grief is the love we have for those we've lost, says photographer Caroline Catlin. In this meditation on the intersection of life and death, Catlin shares how her personal journey with loss drove her to capture the elusive moments of grace and beauty that exist even in the hardest moments imaginable.

Biodesigner Natsai Audrey Chieza prototypes the future, imagining a world where people and nature can thrive together. In this wildly imaginative talk, she shares the vision behind her innovation lab, which works at the intersection of nature, technology and society to create sustainable materials and models for the future. Chieza invites us to consider what kind of world we wish for -- and what systemic changes and collaborations need to happen for it to exist.

The single most important thing for avoiding a climate disaster is cutting carbon pollution from the current 51 billion tons per year to zero, says philanthropist and technologist Bill Gates. Introducing the concept of the "green premium" -- the higher price of zero-emission products like electric cars, artificial meat or sustainable aviation fuel -- Gates identifies the breakthroughs and investments we need to reduce the cost of clean tech, decarbonize the economy and create a pathway to a clean and prosperous future for all. (This virtual conversation, hosted by TED Global curator Bruno Giussani, was recorded in March 2021.)

Higher education remains rooted in rigid, traditional structures and tracks -- and it's at risk of getting left behind in favor of expanded access, greater flexibility and tailored learning. Educator Tyler DeWitt explains how innovations in digital content and virtual reality are ushering in the future of learning, emphasizing why academia must adapt to this new reality and embrace an approach to education that works with students' needs -- not against them.

"We need to figure out how we go into conversations not looking for the victory, but the progress," says world debate champion Julia Dhar. In this practical talk, she shares three essential features of productive disagreements grounded in curiosity and purpose. The end result? Constructive conversations that sharpen your argument and strengthen your relationships.

What if we could use biology to restore our balance with nature without giving up modern creature comforts? Advocating for a new kind of environmentalism, scientist and entrepreneur Emily Leproust rethinks modern sustainability at the molecular level, using synthetic biology to create green alternatives. From lab-developed insulin and disease-resistant bananas to airplanes made of super-strong spider silk, she explains how reading and writing DNA can lead to groundbreaking innovations in health, food and materials.

When you report an emergency in the US, police, firefighters or paramedics answer the call. What if mental health professionals responded, too? Colorado State Representative Leslie Herod shares a straightforward and research-backed approach that brings heart and humanity to criminal justice rather than unnecessary fines and arrests -- and keeps crises from escalating into traumatic, or even deadly, events.

The COVID-19 pandemic changed the way we work for good. Can it also change it for the better? Consultant Patty McCord reviews four key insights employers and employees alike gleaned from their shift to working from home -- and shares how companies can use what they learned in lockdown to creatively and innovatively rethink how we do business.

How do companies like SpaceX make sudden breakthroughs on decades-old challenges? Emerging tech expert Antoine Gourévitch explains how deep tech -- a new approach to innovation that merges science, engineering and design thinking -- is unlocking solutions to problems in space exploration, biology, energy and more. As Gourévitch says: "[deep tech] is changing what was once considered impossible into something actively possible, today."

Picture your favorite place in nature. How would you feel if it disappeared tomorrow? In this love letter to the planet, social worker and environmental activist Knut Ivar Bjørlykhaug invites us to confront the deep, difficult emotions -- love, sorrow and even rage -- born from climate-driven ecological loss in order to act in service of our collective home.
