Play Can Turning CO2 to Stone Help Save the Planet?

Caitlin Saks and Arlo Pérez Esquivel, joined by Alex Clark, investigate how the planet naturally turns CO2 into stone, and how scientists are trying to speed up this process. Cornell University Environmental Engineer Greeshma Gadikota illustrates how you can test out carbon sequestration at home. Lamont Doherty Earth Observatory’s Angela Slagle explores scaling up CO₂-to-stone transformation.

Play Is Biodegradable Plastic Actually Possible?

The Earth is covered in plastic—and we keep making more of it. Caitlin Saks and Arlo Pérez Esquivel join chemist Malika Jeffries-EL in her Boston University lab to explore just what it takes to break down plastics. Berkeley scientist Ting Xu shows how her lab is innovating a truly biodegradable plastic that fully breaks down plastic into its constituent molecules—in nature—in a matter of WEEKS.

Play Glass Is Making Your Internet Faster

Caitlin and Arlo visit the Diablo Glass School to discover how chemistry plays an important role in glass’s versatility, and how its properties can be manipulated. Dr. Desiré Whitmore — also known as “LaserChick” — uses lasers to demonstrate how information can be transmitted through glass, and explains how that forms the basis of an ever-growing global fiber optic network.

Play This Explosive Gas is Heating our Planet. Can we Capture it?

Controlling methane leaks and emissions is crucial for controlling global climate change. Hosts Caitlin Saks and Arlo Pérez Esquivel investigate this tricky molecule by tracing it to its source, in nature and in the city. They investigate why this molecule is so efficient at heating both our homes and our planet—and how scientists are trying to stem the flow of the molecule into the atmosphere.

Play What Does Sweat Have to do with the Global Water Crisis?

Why is water so crucial to us—and to all life on Earth? Out of Our Elements hosts Caitlin Saks and Arlo Pérez Esquivel examine their sweat to understand how the molecular structure of water makes it crucial for life as we know it. They also explore how the same molecular properties that make water essential for life come with a downside, helping to explain why we are facing a global water crisis.
