Jellyfish are an enigma. They have no centralized brain, but they see and feel and react to their environment in complex ways. They look simple, yet their propulsion systems are so advanced that engineers are just learning how to mimic them. They produce some of the deadliest toxins on the planet and still remain undeniably alluring. Long ignored by science, they may be a key to ecosystem stability. Juli Berwald's journey into the world of jellyfish is a personal one.

Coral reefs are a microcosm of our planet: extraordinarily diverse, deeply interconnected, and full of wonders. When they’re thriving, these fairy gardens hidden beneath the ocean’s surface burst with color and life. They sustain bountiful ecosystems and protect vulnerable coasts. Corals themselves are evolutionary marvels that build elaborate limestone formations from their collective skeletons, broker symbiotic relationships with algae, and manufacture their own fluorescent sunblock.
