Just about every solid, liquid or gas in the world as we know it begins with reactions between individual atoms and molecules. Host David Pogue dives into the transformative world of chemical reactions, from the complex formula that produces cement to the single reaction that has allowed farmers to feed a global population by the billions — a reaction that, when reversed, unleashes the powerful chemistry of high explosives.

Glass so strong you can jump on it, rubber so tough it protects a clay pot dropped from 50 feet, endless varieties of plastic. Scientists and engineers have created virtually indestructible versions of common materials by manipulating the chains of interlocking atoms that give them strength, but have they made them too tough? Host David Pogue explores the fantastic chemistry behind the everyday materials we depend on, and how the quest for durability can be balanced with products’ environmental impact.

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 are all made of — literally.

Follow along as NASA launches the Mars 2020 Mission, perhaps the most ambitious hunt ever for signs of life on Mars. It will be the first time a rover will land in Jezero Crater, an ancient river delta that could possibly be a cradle of life. Jezero is also one of the most dangerous areas for a spacecraft to land. If the landing is successful, a solar-powered rover and a four-pound helicopter will comb the area for signs of life until 2030 and collect samples for a possible return to earth. Did life ever exist on the red planet? How would discovering evidence of it change our life here on earth?
