A 2022 survey found growing numbers of Republicans and Democrats think the other side is immoral and dishonest. Psychology and neuroscience research offers tools to help bridge that divide.
The first full map of an adult fruit fly’s brain shows 50 million connections between neurons. Researchers are using the map to learn how all brains work.
Early in life, the protein Reelin helps assemble the brain. Later on, it appears to protect the organ from Alzheimer’s and other threats to memory and thinking.

We've all been there: You sit down for one episode of a reality TV show, and six hours later you're sitting guiltily on the couch, blinking the screen-induced crust off your eyeballs.
Okay. Maybe you haven't been there like our team has.

It turns out that experiencing – and studying – pleasure is not as straightforward as it might seem. And yet, pleasure is quite literally key to the survival of humanity. So today on the show, we explore the pleasure cycle: What it is, where it lives in the brain and how to have a healthier relationship with the things that make us feel good.
