What if one of the most powerful tools for restoring your mental health, sharpening your focus, and cultivating optimism has been outside your door all along? In this episode of Blue Sky, neuroscientist Marc Berman — pioneer of the field of environmental neuroscience and author of Nature and the Mind — shares groundbreaking research on how nature literally rewires the brain.

From his path to coining "environmental neuroscience" to surprising findings about what even a simple walk in the park can do for your attention and mood, Marc reveals the science behind something we've always intuitively felt — that time in nature just makes us feel better. And now we know why.

In a world of constant digital stimulation and screen fatigue, this episode offers both a scientific framework and a simple, hopeful prescription.

What if the relentlessly negative news cycle is giving us a distorted picture of reality? In this episode of Blue Sky, Charles Kenny from the Center for Global Development makes a compelling, data-driven case that the world is truly getting better — in ways most of us rarely hear about.

From dramatic reductions in global poverty and child mortality to rising living standards across the developing world, Charles unpacks the economic evidence that challenges our collective pessimism. He explores how technological advancements and shifting global perspectives are quietly reshaping human welfare for the better — and why that story isn't getting told.

If you've ever felt overwhelmed by doom and gloom, this episode is your antidote.
