This is Your Brain on HormonesAfter reading something that said her menstrual cycle changes her brain each month, Senior Correspondent Molly Webster goes on a reporting mission to see if that’s true, and, if so, how. This journey into sex hormones and the brain involves females and males, and exacting self-experimentation. It gets into PTSD, and ends with a new twist on self-care (hint: it’s biological). And, it starts to reveal a sneaky truth: that each one of us is at the mercy of a crashing sea of chemicals inside of us – those things we call hormones. Special thanks to Emily Jacobs, Laura Pritschet, Pavel Shapturenka, and Dr. Catherine Woolley.

Bonus: Wild Animal Dads from TerrestrialsIn honor of Father's Day, here is a family friendly bonus episode from our kids' podcast Terrestrials. What does it really mean to be a dad? In the animal world, fathers have long been painted as aggressive or absent. At best providers and protectors, but certainly not caregivers. And yet for every tale of a lion or chimp dad eating its own young (yikes!), there’s another creature who tells a sweeter story. Two HUMAN dads bring us on this DADventure: Dr. Eduardo Fernandez-Duque, who has spent decades studying owl monkey dads in the forests of Argentina, and Michael Feigelson, who once worried he wasn't cut out for the softer side of parenting. They introduce us to seahorse dads who get pregnant, poison dart frog dads who give piggyback rides to their tadpoles, Darwin frogs who swallow their eggs to keep them safe, burying beetles who build "corpse cribs," jacana birds who do all the egg-sitting, and stickleback fish who construct intricate underwater nests for their young. Along the way, we learn that nature doesn’t offer just one model of fatherhood. Alongside Mother Nature... there just might be a Father Nature, too. Special thanks to the Van Leer Foundation for the support of this episode.
