    "prose": "The Soviet nuclear submarine K-278 Komsomolets sank in 1989 in the Norwegian Sea southwest of Bear Island and now lies at about 1,680 meters depth, carrying a reactor and two torpedoes with atomic warheads. [^1]\n\nAdvances in understanding the nature of these systems at the time of life's origins demand renewed scrutiny. [^2]\n\nBecause the ancient oceans were sulfate- and sulfide-poor and serpentinizing systems contain little sulfur, sulfide would have been virtually absent from ancient Lost City-type vents. [^3]\n\nThe evaluation presented challenges currently formulated alkaline vent hypotheses for the origin of life and demands a reappraisal of the potential for life beyond Earth. [^4]\n\nAccording to a PNAS study, concentrations of strontium-90 and cesium-137 found near the K-278 Komsomolets wreck are up to 800,000 times higher than normal values in the area. [^5]\n\nJustin Gwynn, the lead researcher of the Komsomolets study, told Spanish newspaper El País that no weapons-grade plutonium was found in water and sediment samples collected near the submarine's hull.
