    Ever wondered how silver journeys from ancient rock formations to the tech in your pocket? In this episode of Don't Panic Geocast, we dig deep into the fascinating world of silver—the metal that's shaped economies, inspired legends, and powers modern technology. From its formation in Earth’s crust to the precise science of extraction and refining, we’ll explore how silver’s unique properties make it indispensable in everything from solar panels to medical tools.

    This week, we dive into the fascinating world of coal—its origins, types, and the role it has played in shaping economies, past and present. We discuss coal’s formation in ancient swampy environments, the journey from mining to electricity generation, and the transition we’re witnessing as the world moves toward renewable energy sources.

    Episode 400 - "Mushroom Cloud of Salt"
    2024/11/01
    Throughout human history, certain minerals have held immense power, shaping economies, societies, and entire civilizations. In this economic rocks series, John and Shannon discuss how essential minerals like salt, gold, and coal influenced historical events and continue to impact modern geopolitics. This week we start with salt and how it is essential to many aspects of our day to day.

Fun Paper Friday This week's Fun Paper Friday features a study on the leaf-mimicking abilities of Boquila trifoliolata. The vine is capable of changing the shape and size of its leaves to resemble those of neighboring plants, potentially as a form of camouflage against herbivores. But the most surprising part? It can even mimic artificial plastic leaves. This finding challenges existing theories that leaf mimicry is driven solely by chemical signaling or genetic exchange between plants, suggesting instead that Boquila may possess a form of plant vision through specialized light-sensitive cells called “plant ocelli.” This discovery opens new possibilities for understanding plant sensory and adaptive behaviors.

    This week, we delve into the fascinating world of the ancient dwelling mounds—terps—of the northern Netherlands. These man-made mounds served as elevated homes for communities living in low-lying, flood-prone areas. Join us as we explore the geology of these mounds, why they were essential for survival, and how modern technology is used to monitor soil subsidence and preserve these unique archaeological sites.

Fun Paper Friday Summary: In this episode’s Fun Paper Friday, we discuss B.F. Skinner’s “Pigeons in a Pelican.” The paper recounts the story of "Project Pigeon," a World War II experiment that explored using pigeons to guide missiles by pecking at visual targets. Though the project faced skepticism and was never implemented in combat, it highlighted the potential of animal training and laid a foundation for behaviorist research. The study is a testament to how creative ideas can push the boundaries of science, even if they seem outlandish at first. Skinner, B. F. (1960). Pigeons in a Pelican.
