Researchers have discovered an extensive hydrothermal vent system near the Greek island of Milos, revealing previously unknown activity along active fault lines. The find, made during a recent expedition, highlights the island's role as a key site for studying tectonic and volcanic processes in the Mediterranean. Depths of the vents range from 100 to 230 meters, reshaping understandings of regional geology.

Researchers have identified vast deposits of lava rubble beneath the South Atlantic Ocean that trap significant amounts of carbon dioxide over tens of millions of years. These breccia formations, formed from eroded underwater mountains, store far more CO2 than typical ocean crust samples. The discovery highlights a previously unrecognized mechanism in Earth's long-term carbon cycle.
