Hydrothermal Activity Discovered Along The Puy de Folles Vent Field
NOAA, Schmidt Ocean Institute, and partners recently embarked on the In Search of Hydrothermal Lost Cities expedition on the Schmidt’s Research Vessel Falkor (too) to locate and observe hydrothermal vent […]
Pythia’s Oasis Has Warm liquid Spewing From The Seafloor Offering Clues To Earthquake Hazards
Editor’s note: Pythia’s Oasis is a newly-discovered seafloor seep off the coast of Oregon featuring water with a unique composition from an exceptionally deep location inside Earth. A varied ecosystem […]
Metagenome Mining And Functional Analysis Reveal Oxidized Guanine DNA Repair At The Lost City Hydrothermal Field
The GO DNA repair system protects against GC → TC mutations by finding and removing oxidized guanine. The system is mechanistically well understood but its origins are unknown. We searched […]
The Genetics Of Temperature Adaptation: How Does Life Thrive In Extreme Conditions?
The history of the Earth has been one of physical extremes—extreme atmospheric conditions, extreme chemical environments, and extreme temperatures. There was a time when the Earth was so hot all […]
Life In The Smoke Of Underwater Volcanoes
Deep down in the ocean at tectonic plate boundaries, hot fluids rise from so-called hydrothermal vents. The fluids are devoid of oxygen and contain large amounts of metals such as […]
Immense Diversity And Interdependence In High Temperature Deep-Sea Microorganism Communities
A new study by researchers at Portland State University and the University of Wisconsin finds that a rich diversity of microorganisms live in interdependent communities in high-temperature geothermal environments in […]
How Enceladus Ejects Particles From Oceans Beneath Its Surface
Although it is relatively small, Enceladus — the sixth largest of Saturn’s 83 moons — has been considered by astronomers to be one of the more compelling bodies in our […]
Deep-sea Black Carbon Comes From Hydrothermal Vents
Hydrothermal vents have been identified as a previously undiscovered source of dissolved black carbon in the oceans, furthering the understanding of the role of oceans as a carbon sink.
Prebiotic Chemistry Has Been Observed Around Shallow-Sea Vents
NASA-supported Astrobiologists have revealed that alkaline hydrothermal vents in shallow seas could have been a favorable environment for the chemistry leading up to the origin of life on the early […]
