Maybe it’s your grandmother’s molasses cookies, the garlicky tomato sauce your spouse cooked when you were first dating, or the chicken noodle soup you made every week when your kids were little. The sights, smells and tastes of certain foods can instantly remind us of a person or transport us back to a particular time in our lives. In this episode, we’ll meet kitchen ghosts from Kentucky, hear how religion and food are intertwined, and talk about how flavor evokes emotion – from grief to joy.

Before family photos, or school pictures or Instagram, there were hand-drawn and painted portraits. Throughout the ages, portrait artists have captured expressions and personalities on canvas or paper, and those who view the picture interpret this “likeness” in their own way. We talk with a philosopher, a musician and a novelist about the role of portraits through history, and how we see ourselves —and others — through these deeply personal images.

We get the message before we’re out of training pants – when the going gets tough, look on the bright side, make lemonade out of lemons and just do it. We’re going to consider the exact opposite – the wisdom of giving up and letting go. Because sometimes, the strongest and most courageous thing you can do is walk away.

Have you ever wondered how plants find enough light and water? How they ward off attacks from predators? It turns out they’re a lot smarter than you realize. Some plants can hear a caterpillar munching on its leaves and then send out distress signals to activate their immune system. Certain flowers can trick bees into pollinating them, even when there’s no pollen. Plants also have memories. And they may even be able to see.
