There’s this idea that something happens in the human brain when we turn 25. Suddenly, we can rent a car without fees. Make rational decisions. We may even regret some of our past… indiscretions. All because we’re developed…right? Well, a recent paper in the journal Nature suggests that may not be the case. Neuroscientists found four distinct turning points in brain development across the human lifespan – and that the brain may be in its “adolescent” phase until about the age of 32. Interested in more of the science inside your brain?

In the mid-1980s, scientists published a startling finding–a giant hole in the ozone layer over Antarctica. That’s the protective shield that blocks large amounts of harmful UV radiation. And without it, the rate of cancer, cataracts and crop failure would skyrocket. Today on the show, we dive into ozone science and examine how scientists successfully sounded the alarm and solved an Antarctic mystery.Check out our episode on an Antarctic plankton mystery.

Microbes are little alchemists that perform all manner of chemical reactions. A team of microbiologists co-founded a non-profit to try to harness those abilities to solve some of the world’s big problems — from carbon capture to helping coral reefs to cleaning up waste. Recently, the team turned their attention to the microbes living in people’s homes — on and in shower heads, drip pans, and hot water heaters. These rather extreme environments may have pressured microorganisms into surviving in ways that could be advantageous to humans. Science reporter Ari Daniel takes us on a treasure hunt in miniature.This episode was produced by Hannah Chinn. It was edited by Rebecca Ramirez. Tyler Jones checked the facts.
