A mouse with two dads — and a new frontier for biology | Katsuhiko Hayashi

You're familiar with the story: a sperm and an egg meet to create an embryo, which has the potential to give rise to new life. But what if you could create a sperm or egg from any cell, even a single skin cell? Biologist Katsuhiko Hayashi discusses the science of in vitro gametogenesis (IVG) — an experimental technique for creating lab-made sperm or eggs out of just about any type of cell — and explores its implications for endangered species, human reproduction and more.

Why I risked my life to expose a government massacre | Anjan Sundaram

Why I risked my life to expose a government massacre | Anjan Sundaram

A war zone can pass for a mostly peaceful place when no one is watching, says investigative journalist and TED Fellow Anjan Sundaram. In this short, incisive talk, he takes us inside the conflict in the Central African Republic, where he saw the methodical preparation for ethnic cleansing, and shares a lesson about why it's important to bear witness to other people's suffering. "Ignored people in all our communities tell us something important about who we are," Sundaram says. "A witness can become precious, and their gaze most necessary, when violence passes silently, unseen and unheard." Hosted on Acast. See acast.com/privacy for more information.

The world doesn't need more nuclear weapons | Erika Gregory

Today nine nations collectively control more than 15,000 nuclear weapons, each hundreds of times more powerful than those dropped on Hiroshima and Nagasaki. We don't need more nuclear weapons; we need a new generation to face the unfinished challenge of disarmament started decades ago. Nuclear reformer Erika Gregory calls on today's rising leaders -- those born in a time without Cold War fears and duck-and-cover training -- to pursue an ambitious goal: ridding the world of nuclear weapons by 2045.

The lies we tell pregnant women | Sofia Jawed-Wessel

A better way to talk about love | Mandy Len Catron

A better way to talk about love | Mandy Len Catron

In love, we fall. We're struck, we're crushed, we swoon. We burn with passion. Love makes us crazy and makes us sick. Our hearts ache, and then they break. Talking about love in this way fundamentally shapes how we experience it, says writer Mandy Len Catron. In this talk for anyone who's ever felt crazy in love, Catron highlights a different metaphor for love that may help us find more joy -- and less suffering -- in it. Hosted on Acast.
