Groundwater is our hidden savings account. Learn how scientists map water-table depth using wells, satellites, and machine learning - and why shallow groundwater across large areas matters for ecosystems, contamination risk, and drought resilience.

Innovation drives economic growth - but the planet has limits. We translate “creative destruction” into Earth terms: resource booms, energy transitions, and why sustained growth only works long-term if it respects geologic and climate boundaries.

Science fiction is turning into science fact. We explore “de-extinction” efforts like woolly-mammoth traits and dire-wolf headlines - plus the ethics of altering nature, ecosystems, and what we owe to living species today.

Is Tornado Alley moving? In this episode, we analyze the geological and meteorological forces shifting the center of tornado activity from the Great Plains to the Southeast. We explore how flat sedimentary basins fuel supercells, the role of climate change in this migration, and what the rising threat means for preparedness in Kentucky and Tennessee.

Kentucky bourbon has a geologic signature. Discover how limestone-filtered water removes iron, adds key minerals for fermentation, and helps set the stage for bourbon’s smooth character.
