The idea that depression comes from a chemical imbalance in the brain has shaped treatment for decades. Neuroscientist Lisa Monteggia shares research suggesting that’s not the whole story — and shows how a decades-old drug could upend what we thought we knew about depression, with the potential to offer relief within hours.

What if science class felt less like studying out of a textbook and more like an unforgettable field trip? From viral glitter-bomb traps to backyard engineering marvels, former-NASA-engineer-turned-YouTuber Mark Rober has spent years proving that curiosity is contagious — and that the best way to teach science is to make it impossibly fun. In conversation with TED’s Whitney Pennington Rodgers, Rober shares how play, wonder and a healthy dose of mischief can transform the way kids learn … and gives a peek inside his plan to bring magic to every classroom in America. (This conversation was part of an exclusive TED Membership event. TED Membership is the best way to support and engage with the big ideas you love from TED. To learn more, visit ted.com/membership.)
