Discover the chemical reactions that transform our world. Like one that enables us to feed billions but when reversed, is explosive. And lock-and-key molecules that put the heat in hot peppers or make deadly venoms useful to medicine.

Scientists have created virtually indestructible versions of glass, rubber, and plastic. But are they too tough? As the environmental impact of the quest for durability becomes clear, scientists seek to maintain utility but minimize harm.

Without the chemistry of photosynthesis, ozone, and a molecule called Rubisco, none of us would be here. So how did we get so lucky? To find out, host David Pogue investigates the surprising molecules that allowed life on Earth to begin, and ultimately thrive. Along the way, he finds out what we’re all made of--literally.
