How cohousing can make us happier (and live longer) | Grace Kim

Juli 24, 2017 - 14:52
Loneliness doesn't always stem from being alone. For architect Grace Kim, loneliness is a function of how socially connected we feel to the people around us -- and it's often the result of the homes we live in.

Rethink your home and how you live in it with this eye-opening talk.

Juli 20, 2017 - 14:55
The divisiveness plaguing American politics today is nothing new, says constitutional law scholar Noah Feldman. In fact, it dates back to the early days of the republic, when a dispute between Alexander Hamilton and James Madison led the two Founding Fathers to cut ties and form the country's first political parties. Join Feldman for some fascinating history of American factionalism -- and a hopeful reminder about how the Constitution has proven itself to be greater than partisanship.

How your brain hallucinates your conscious reality | Anil Seth

Juli 18, 2017 - 15:00
Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it.

Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

Climate change is real, case closed. But there's still a lot we don't understand about it, and the more we know the better chance we have to slow it down. One still-unknown factor: How might clouds play a part? There's a small hope that they could buy us some time to fix things ... or they could make global warming worse. Climate scientist Kate Marvel takes us through the science of clouds and what it might take for Earth to break its own fever.
