First up, we examine a question that most kids ask at some point: “Where do babies come from?” Science writer Edward Dolnick walks us through how humanity discovered the answer to that question. And the story involves Leonardo Da Vinci, sea urchins, and staring at sperm under a primitive microscope.

After that: What can scientists learn from the natural world? We visit the lab of Jeff Karp, a biomedical engineer who seeks inspiration from porcupines and geckos. Take a listen to find out how investigating sea slug slime led to the development of a glue that can adhere to almost any tissue in the human body. (The glue actually just received market approval in Europe.)

Finally, humans are living longer and longer. What does that mean for our society? Andrew Scott, co-author of The 100-Year Life: Living and Working in an Age of Longevity, believes that we’re going to have to create entirely new stages* *of life.
