    How your memory works -- and why forgetting is totally OK | Lisa Genova

    How your memory works -- and why forgetting is totally OK | Lisa Genova

    Have you ever misplaced something you were just holding? Completely blanked on a famous actor's name? Walked into a room and immediately forgot why? Neuroscientist Lisa Genova digs into two types of memory failures we regularly experience -- and reassures us that forgetting is totally normal. Stay tuned for a conversation with TED science curator David Biello, where Genova describes the difference between common moments of forgetting and possible signs of Alzheimer's, debunks a widespread myth about brain capacity and shares what you can do to keep your brain healthy and your memory sharp.

    The electrical blueprints that orchestrate life | Michael Levin

    The electrical blueprints that orchestrate life | Michael Levin

    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.)

    Your teeth carry secrets: centuries of history about your ancestors, from where they lived to what they ate and where they traveled. Bioarchaeologist Carolyn Freiwald traces the story of human migration across the Americas -- from Mayan royalty and Belizean buccaneers to rural Appalachian farmers -- to illustrate what ancient teeth can reveal about you.

    The promise of quantum computers | Matt Langione

    The promise of quantum computers | Matt Langione

    What if tiny microparticles could help us solve the world's biggest problems in a matter of minutes? That's the promise -- and magic -- of quantum computers, says Matt Langione. Speaking next to an actual IBM quantum computer, he explains how these machines solve complex challenges like developing vaccines and calculating financial risk in an entirely new way that's exponentially faster than the best supercomputers -- and shares why industries should prepare now for this new leap in computing.

    A stellar history of modern astronomy | Emily Levesque

    A stellar history of modern astronomy | Emily Levesque

    Astronomers once gazed upon the night sky and counted every star in the galaxy by hand. The process has evolved since then, but the thirst for celestial knowledge remains the same. Join astrophysicist Emily Levesque for an anecdote-rich jaunt through the technological history of photographing the cosmos and learn about the one constant that makes it all work: human curiosity.

    How COVID-19 human challenge trials work -- and why I volunteered | Sophie Rose

    How COVID-19 human challenge trials work -- and why I volunteered | Sophie Rose

    In April 2020, epidemiologist-in-training Sophie Rose volunteered to be infected with the virus that causes COVID-19. As a young, healthy adult, she's offering to take part in a human challenge trial, a study where participants are intentionally exposed to SARS-CoV-2 to test vaccines and gather critical data. Explaining how challenge trials could speed up the development of effective vaccines, Rose shares why volunteering was the right decision for her.
