Today's show begins with a report on another blackout in Cuba -- and how the island's struggles have prompted many to leave their home country. Then, we're launching into a two-part series that examines the good, the bad, and the potentially dangerous when it comes to illicit gold mining in West Africa. We're taking you to the continent's savannah to explain how an invasive insect might've altered the diet of an apex predator. And we're having a bit of fun with cats in the snow!
