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

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.

Hamilton vs. Madison and the birth of American partisanship | Noah Feldman

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

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.

Can clouds buy us more time to solve climate change? | Kate Marvel

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? They’re critical in regulating earth’s temperature, and there’s a small hope that they could buy us some time to fix things. Climate scientist Kate Marvel takes us through the science of clouds and what it might take for the earth to break its own fever.

What rivers can tell us about the earth’s history | Liz Hajek

Rivers are one of nature’s most powerful forces — they bulldoze mountains and carve up the earth, and their paths are constantly changing. Understanding how they form and how they’ll change is important for those that call their banks and deltas home. In this visual-packed talk, geoscientist Liz Hajek shows us how rocks deposited by ancient rivers can be used as a time machine to study the earth’s history, so we can figure out how to more sustainably live on it today.

Why journalists have an obligation to challenge power | Jorge Ramos

You can kick Jorge Ramos out of your press conference (as Donald Trump infamously did in 2015), but you can never silence him. A reporter for more than 30 years, Ramos believes that a journalist’s responsibility is to question and challenge those in power. In this compelling talk — which earned him a standing ovation midway through — Ramos explains why, in certain circumstances, he believes journalists must take sides.
