Guest: Adam Leith Gollner.

What if we could turn sour flavors to sweet in a single nibble? In fact, you can—all you need is one bite of the miracle fruit, an experience described by Adam Leith Gollner in his recent book The Fruit Hunters. Gollner joins the show today to talk about some of the extraordinary fruits that he has discovered around the globe, as well as the mass-produced ones that we may buy in the grocery store.

Guest: Dan Koeppel.

What if Eve's apple in the Garden of Eden was actually a banana? Today on Focus, we're joined by author Dan Koeppel to talk about the history of the popular fruit, as well as the danger it is currently facing from a fast-moving blight in plantations worldwide. In the race to save this beloved snack, bananas grown in test tubes may be our last hope.
