Coral reefs are fighting for their very survival these days, and scientists are looking for ways to help—including testing underwater AC systems, and 3D printing what one might describe as artificial coral cyborgs. Hosted by: Savannah...

Dams are great for humans, providing hydroelectricity and flood control. They're also horrible for the rivers they block. Here are three success stories of ecosystems that bounced back after a dam was removed. Hosted by: Savannah Geary...

One of game theory's most famous quandaries is the Tragedy of the Commons. But, through her years of research, Nobel Prize winner, Elinor Ostrom, showed us that we're not doomed to tragedy after all. Hosted by: Stefan Chin (he/him)

China's Zhangye Danxia National Geopark is home to strikingly beautiful rainbow mountains -- yes, what you're seeing is real! But the secret to this amazing sight might be something incredibly humble: dirt. Hosted by: Stefan Chin (he/him)

This lake in Canada sports a stunning summer look - spots! And the weird geology and hydrology that makes these spots is definitely worth talking about. Plus, Spotted Lake may not be the only one of its kind, and might tell us more about...

The Chocolate Hills of Bohol, Philippines are so perfectly shaped that local legends say they were crafted by giants. Geologists can't agree exactly what happened, but the answer might be as simple as limestone, water, and wind. Hosted...

It's one of the great boomer vs. millennial debates: Do you have to sort your laundry? It's tedious to pull apart lights and darks, hot water and cold water, but thanks to advancements in science, that all may be a thing of the past....
