Conservation biologist Tim Shields sees urgency in the field and finds that traditional conservation practices are lacking when it comes to saving desert tortoise populations from ravens. He goes rogue, employing an arsenal of lasers, exploding model turtles, drones and desert rovers as a means of protecting the tortoise's dwindling numbers.

Biologist Joanne Chory is undertaking the final mission of her lauded career: supercharging crop plants to sequester carbon deep into Earth's soil, with the goal of cutting the pace of climate change in half. But she’s racing the two ticking clocks of ecological collapse and her own advancing Parkinson’s disease.

Eric Sun found out he had a brain tumor and a year to live. Instead of experimental treatments, he decided to attempt to master the violin.

Memory care pioneers build a replica 1950s town, challenging Alzheimer's care norms while families desperately await a breakthrough.
