Satellites Map a 5,000-Mile Sargassum Belt Hidden Across the Atlantic
Space-based sensors have revealed the Great Atlantic Sargassum Belt in full for the first time — a continuous, living structure spanning more than 5,000 miles across the tropical Atlantic that no ship survey could ever perceive as a whole.
Colombia’s Three Colliding Tectonic Plates Made the Chocó Quake Inevitable
A magnitude 7.4 earthquake killed at least 169–280 people in Chocó, Colombia — and geologists say the science behind it was inevitable. Colombia sits where the Nazca, South American, and Caribbean plates all converge, creating one of the Western Hemisphere's most dangerous seismic zones.
Why Rivers Are Running Dry Decades Before Hydrology Models Predicted
Three interacting mechanisms — atmospheric moisture demand, severed groundwater buffers, and soil moisture debt — are draining rivers like the Rio Grande and Colorado decades ahead of what hydrological models forecast, forcing researchers to revise core water cycle assumptions.
Ancient Amazon Civilization May Have Held 3 Million People, LiDAR Reveals
Airborne laser scanning is dismantling the long-held idea that the Amazon was too poor to sustain large societies, uncovering planned cities and engineered landscapes that may have supported millions before European contact.
A New Frog Species Hid Undetected in NYC — and It’s Probably Not Alone
A new leopard frog species evaded science for decades on Staten Island because it looked identical to known relatives — and researchers now suspect undescribed insects and other organisms are hiding across New York City's neighborhoods.
Biggest Earthquake Ever: How Valdivia’s 9.5 Killed People 10,000 Miles Away
The 1960 Valdivia earthquake registered magnitude 9.5, the highest ever recorded, and unleashed a tsunami that traveled nearly 10,000 miles to kill people in Hawaii, Japan, and the Philippines. Here's the geology and scale behind history's most powerful seismic event.Load More
