A New Bacterial Species From A Hydrothermal Vent Throws Light On Their Evolution

by Keith Cowing

Deep-sea hydrothermal vents are hot springs on the ocean floor. Sea water penetrates into the ocean crust, becomes heated, and rises to the seafloor surface carrying dissolved nutrients. Around these […]
