The days of diamond mining may be numbered, and lab-grown stones have become almost indistinguishable from those pulled from the earth. In this episode, we talk to the diamond dealers and growers hedging against a future in which the mines run dry.

The wars of the future will be fought in megacities around the world by soldiers connected - and possibly even augmented - by neural implants and AI. In this episode, we examine how military leaders are preparing for a radical shift in combat.

The restaurant industry is embracing automation, from robot-staffed espresso bars to fully automated burger chefs. In this episode, we explore what this means for workers, diners and--most importantly--the quality of our food.

In labs around the world, scientists are using gene-editing technology to revive species that disappeared from the face of the earth long, long ago. In this episode, we talk to the researchers working on a project straight out of science fiction.

Football-playing robots. Algorithmic umpires. Neurological performance enhancement. In this episode, we look at how science and technology are reshaping the playing field - and how these advances could benefit life beyond sports.

Agriculture is turning to automation as it grapples with growing demand and a shrinking labor force. In this episode, we meet the robots making farms more efficient.

In this episode, we watch hackers compromise voting machines and hear from technologists hoping to safeguard democracy with help from blockchain and mobile voting. Can tech protect our democratic process from foreign interference?
